Development thread for Linux on the HTC HD2
PLEASE READ THE FAQ BEFORE POSTING QUESTIONS
Introduction:
To run any Linux based user space on a device -this includes android, debian, ubuntu, openembedded, etc- you need a working Linux kernel.
This thread discusses the development on Linux kernel and user space on the HTC HD2.
All android ports to windows phones are based on the efforts of porting the Linux kernel to these devices. This is what all the porting is about. Nobody is porting Google Android to these phones. It works already.
Contributing:
This is not a secret club. All source code and development information is publicly available. Everybody who is willing to contribute is free to join the development process.
People working on porting Linux to HD2:
You can donate to the developers putting a lot of time into this Linux kernel port.
(putting together android files (=>making "roms") is not the porting)

working flashlight
ppp stability
usb stability (works with windows7 now)
fixed usb host mode kernel
working backlight control in normal Linux distros
working WiFi master (access point) mode: enables tethering (you might need to update firmware files. )
09/05/2010 We have been working on a new kernel base for the HD2 for few days now. Markinus started the initiative by introducing our present HD2 specific changes in the EVO4G release kernel source code. Right now the htc-msm-2.6.32 branch is still more advanced. We might create an autobuild for the EVO4G base kernel in case it will be superior at some point.
Builds
Global notes:
*None of the current releases will touch your internal flash. After restart you are back in the usual winmo.
*When Linux is booted, windoes mobile is shutdown abruptly. Although this is very rare it can cause some data loss. Please save your work and make frequent backups!
*You need at least a 2.08 radio rom version installed on your HD2. If yu have an older version you might not be able to boot Linux.

Click here to view autobuild history (archived dated zImages and modules)
Most recent zImage (Linux kernel image)
zImage-htcleo-latest
The Linux kernel is the core element of your operating system. It contains most of the drivers. It is supplied in form of a compressed (gzipped) executable binary Image. Along with an initial rootfilesystem aka initrd it is loaded into memory and executed by the bootlaoder HaRET.
Most recent Linux kernel modules to match zImage-htcleo-latest (has bcm4329.ko)
modules-htcleo-latest.tgz
Kernel modules are drivers that are not included in the zImage. They go seperately in .ko files. bcm4329.ko holds the wifi driver and tun.ko is needed for tunneling. For android use you must extract the modules.tgz file, search for the .ko files you need and copy them into /system/lib/modules/ directory. See FAQ for how to copy files into your android install.
HaRET (bootloader)
HaRET.exe
The haret bootloader is used to start Linux according to the instructions it reads from the file default.txt . If HaRET sees a file called startup.txt it will use this instead and boot Linux directly without any prompt.
startup.txt (bootloader/HaRET configuration - auto updated to match latest GIT kernel)
startup.txt
NOTE: This example configuration only holds the parameters critical to booting with latest GIT. Ask the person supplying you with 'roms' for additional parameters needed. See FAQ section for more detail on parameters.
Android
Please browse the main HD2 Android forum for various recent builds.
It is always important to install a recent kernel. See post #3 for how to.

INSTALLING NEW LINUX KERNEL (zImage) AND MODULES (.ko files)
Three Things to know about the Linux kernel
1) The Linux kernel is the center of your of your operating system. Its core is seated in the kernel image (zImage file - the z means it is compressed). It contains most of the drivers.
2) Some drivers go external via Linux kernel modules (.ko files). E.g. in the HTC HD2 Linux kernel, the WiFi module is supplied as bcm4329.ko
3) The kernel image and kernel modules are made to match. They need to have the exact same version. This means if you pick a random .ko file things might go wrong => Find always up to date kernel image and matching modules here
Editing startup.txt
1) The following lines are needed in startup.txt to make GIT kernels work in any build !
set mtype 2524
set ramaddr 0x11800000
set ramsize 0x1E400000
set initrd_offset 0x00a00000
set kernel zImage
<ADDITIONAL PARAMTERS GO HERE!!!!!!!!1 Remove this line.>

Click to collapse
2)Additionally you need to specify the following. Those parameters are dependent on the build you use. Look them up in your present startup.txt
*Initial ram disk filename (set initrd initrd.gz)
*Command line paramters (set cmdline "foo=bar google=android" )

Installing the latest Linux kernel image (zImage)
1) Download the latest Linux kernel image (right click, save file as)
1a)for Google Android
1b) for classical GNU/Linux based distros (Ubuntu, openemebdded, meego, maemo etc)
Be aware these build links are dynamic and will be updated once the Linux kernel source code is updated. See here for static links
2) Rename the file to zImage
3) Overwrite your old zImage file with the newly obtained zImage file

Click to collapse
Installing the matching Linux kernel modules (.ko files)
1) Download the latest Linux kernel modules to match your kernel image
1a) for classical GNU/Linux based distros (Ubuntu...)
1b) for Google Android
2) Install the modules...
2a) in GNU/Linux
As root run
cd /
tar xvf /path/to/modules-htcleo-usbhost-latest.tgz
Click to expand...
Click to collapse
2b) For Google Android...
extract the modules-htcleo-latest.tgz file
you will notice it contains a directory structure.
example for module locations within modules-htcleo-latest.tgz :
WiFI module:
lib/modules/2.6.32.9-38151-g827fa85/kernel/drivers/net/wireless/bcm4329_204/bcm4329.ko
Network tunneling module:
lib/modules/2.6.32.9-38151-g827fa85/kernel/drivers/net/tun.ko
Yet Another Flash Filesystem module:
lib/modules/2.6.32.9-38151-g827fa85/kernel/fs/yaffs2/yaffs.ko
Basically you want to copy all .ko files you need into /system/lib/modules directory
Learn 3 Methods to do so detailed in the following:
memin1857 said:
Three different methods for replacing bcm4329.ko (which makes wifi work) Method B seems to be the best.
Easiest: (uses winmo, does not use third party app or commands)
A) (MAY ONLY WORK FOR SHUBCRAFT BUILD) Under winmo, create a folder named root inside your Android folder in your sdcard. This folder named root will be the actual root when Android boots up.
For example:
Create this folder structure under winmo:
STORAGE CARD\Android\root\system\lib\modules
and copy the bcm4329.ko file in it. It will look like this:
STORAGE CARD\Android\root\system\lib\modules\bcm4329.ko
Boot Android and the file gets copied to the protected Android file system. (/system/lib/modules)
If you do this from within Android, reboot to take effect.
B) Start a Terminal Emulator within Android. (Install a terminal emulator from market if not already installed) Copy bcm4329.ko to sdcard root beforehand. Filename has to be all lowercase. Enter these commands:
su
mount -o rw,remount /system
cp /sdcard/bcm4329.ko /system/lib/modules
you should get no response and wifi should work immediately.
you may want to make system readonly again with command
mount -o remount r /system
Delete old bcm4329.ko file if it exists at /sdcard/Android/root/system/lib/modules or it will come back on next reboot.
C) Use a third party app like Root Explorer, Droid Explorer, Root Manager, ES File Explorer and copy the bcm4239.ko file to /system/lib/modules which is mounted in read-write (RW) mode.
(DROID EXPLORER RUNS FROM WINDOWS XP/VISTA/7 and uses adb. No reboot required. Others run from within Android)
You can do A, B OR C. You don't need to do them all. Method A had only been tested in shubcraft v1.2b build.
As a fourth way you can use adb command that comes with android sdk. install usb drivers from within android sdk and connect your hd2 with usb debugging enabled. commands are same with terminal just put adb in front of it and run from folder adb is in.
If you copy an incorrect version of bcm4329.ko that is not matched to your zImage kernel wifi will say error and not work.
You can also WAIT for a new build that properly includes these files already to come out.
You can get bcm4329.ko file from http://oe.netripper.com/files/htcleo_autobuild/modules-htcleo-latest.tgz
Open the tgz file with winrar or similar program. The bcm4329.ko file is under lib\modules\2.32.xxxx\kernel\drivers\net\wireless\bcmxxx

GENERAL FAQ
*Some Roms are reported to work better with Android than other Roms. Duttys Roms seem to have the robot voice problem on calls. Miri's WM6.5 v17 Roms and NRGz Energy Roms seem to work best and have fewer problems.
* With some old radio rom versions it is impossible to boot Linux. Make sure you install a 2.08 + Radio. known working Radios are 2.10.50.08_2 and 2.12.50.02_2
* With the working Linux kernel any kind of Linux based userspace can be used on hd2. This includes google android and any other Linux distribution.
* This is a work in progress! Lots of stuff is still missing. Check http://htc-linux.org/wiki/index.php?title=Leo/Status for current state of affairs
* We know about most available sources of Linux kernel code for the snapdragon devices. It is not necessary to point to evo, bravo, nexus etc.
ANDROID TIPS AND HELP
No Sound in Android: Make sure you run clrad.exe BEFORE running the haret.exe file to boot Android. When you run it, it will not do anything but it does run.
Mobile Internet isnt working on TMOUS HD2: T-Mous users have to manually enter the APN for the mobile internet to work. Go into Network, Mobile Networks, APN. If the APN screen is blank press the Windows button and choose "Add APN" from the menu that pops up. Enter the following, Name: epc.tmobile.com, APN: epc.tmobile.com. Leave the rest blank. Then press with Windows button again and save. Your mobile internet will now work.
Setting up APN (Access Point Name) for Wireless Internet (other than TMOUS): Get your settings from *HERE* then on Android goto Settings, Wireless & Networks, Mobile Networks, Access Point Names. If bank press the Windows Button, New APN and enter your details.
For those having issues with WiFi turning on and off: Go to Settings>Wireless and Networks>Wi-Fi settings>Advanced(Windows key)>WiFi sleep policy> Select Never
Green Screen when booting into Android: Pull out and reinsert the battery, restart the phone and try again.
Phone gets stuck when loading Android (progresses very slow or stuck in the same postion for several minutes): Pull out and reinsert the battery. Delete all references to Android from your storage card including the cache folders and any folders Android created. Then copy the downloaded files back to the ROOT of your storage card or where you are supposed to place them (including the AndroidApps and media folders if you have them). Soft reset your device and run the clrad and haret files within 30 seconds of WinMo loading or use a program such as JMZ's Bootloader.
Sleep of Death (not coming out of sleep): Update your Linux kernel image and modules as instructed above, then restart your phone and restart Android. If you keep getting Sleep of Death with the newest Linux kernel image and Linux kernel modules files then reformat your storage card with FAT32 and start over again. Always make sure you run the latest Linux kernel image and modules.
How to install .apk files on Android: Copy the .apk file to your storage card that you want to install. (see kernel guide for android file copying howto) Load Android and run 'Linda File Manager' from the programs list, then browse to 'SD Card' (complete action using Linda File Manager if asked) and then to the folder where you put the .apk file. Note: To see more information on the screen minimise the keyboard, then click 'view' and select 'details'. Once you have found your .apk file click on it then tick 'Use by default for this action' and select 'package installer'. Now just follow the onscreen instructions to install your program. OR you can copy the .apk files to the AndroidApps folder in the ROOT of your Storage Card and they should auto install when Android loads (most of the time).
Battery isn’t charging in Android: Install the latest Linux kernel image and Linux kernel modules as detailed above.
Excessive Power Consumption: Remember that all these builds are still in beta version and not complete. Alot of things are still being ironed out.
Programs and system functions not working (such as Video camera, Bluetooth, Keyboard backlight on sleep, etc): Install the latest Linux kernel image and Linux kernel modules as detailed above.
No Ringtones or Notifications in setup (in DarkStone's Builds): Download the following file http://gamesquare.co.uk/media.zip (copy the link into your browsers address bar or it wont download). Extract the 'media' folder (make sure the folder has sub folders with the sounds inside those) to the root of your SD card. Now go to Settings, Sound and Display, Phone Ringtone or Notification Sound and they should be there.
What is a zImage? zImage is a Linux kernel binary image. It is the core of your operating system containing most of the drivers. The prepended z means that it is compressed with the gzip algorithm, making it smaller than the non compressed Image file.
Can I use more multiple zImage files at the same time? No. Your phone can only execute one Linux kernel at a time. HaRET.exe (the bootloader) reads the kernel filename from startup.txt - You can maintain multiple zImage files on your phone but chose only one via startup.txt
How do I change the background wallpaper? Hold your finger on the screen and select Wallapers from the popup list.
How do I change the settings? Press the Start Menu button on your phone (middle hardware button) to bring up the menu, then select the bottom middle button (settings or preferences depending on your Android build).
I cant update an app thats pre-installed (i.e. facebook or twitter): Download Root Explorer from the Market, then open it and browse to the 'system, app' folder. Delete the apk file of the app you want to update then try downloading and installing it again.
If you are trying out a TEST build of Android then you SHOULD have a basic level of intelligence (laughs quietly to self) so PLEASE use your brain and try to work things out for yourself before posting a question.

USEFUL ANDROID INFORMATION
1. The difference between Desire Builds and Froyo Builds (thanks to memin1857)
Desire build is ripped from an HTC Desire. It is Android version 2.1 (Eclair)
Froyo build is ripped from a Nexus One. It is Android version 2.2 (Froyo)
Froyo is a newer and much faster Android version. It is currently only available on Nexus one officially. Other newer phones will get it eventually.
HTC Sense is the user interface on top of Android. Desire builds have it already. It can be disabled for standard Android interface.
2. Importing WM Contacts into Android (thanks to brownman)
You need PIM Backup, a computer with internet access and a Gmail account.
1. Open PIM Backup on your Windows Mobile device. Select the Backup action and unselect everything but contacts, then hit Next.
2. At the "Select backup filename and folder" screen, unselect the "compress backup" and "binary backup" options, then hit Next.
3. Transfer the BACKUP.PIB file that you just made from your phone to your computer. Change the extension from .PIB to .RAR, then extract the file.
4. The extracted file should be BACKUP.CSC. Simply change the extension to .CSV and import the file to your gmail account. All your contacts can now be imported to your phone through gmail - just follow the instructions given in the phone's contact menu.
or activesync with google http://www.google.com/support/mobile/bin/answer.py?hl=en&answer=138636
3. Putting a Shortcut button on HTC Sense, etc to start Linux (in order to boot Android, Ubuntu, etc)
1. Make sure you have your Android build copied to your Storage Card as instructed earlier in this FAQ
2. Install mskip's Android Loader from *HERE* and install to DEVICE Memory
3. Add a Shortcut Button to your Sense, Mobile Shell or other Today Screen Plugin
4. Click on the button to start Android loading
4. Adding languages to Android Operating SystemBU

Den nye HTC Evo kan jo nærmest ikke sammenlignes med HTC HD2. Andet batteri, HDMI udgang, større kamera, front kamera osv osv. Så nej.

Short version @English:
No. - The Evo has different hardware.
Alright, i booted the image... and the flashlight turned on for a sec, then everything turned black... thats it right?
i had to swap the default.txt to get haret to boot :/
This is only somewhat related, but nonetheless should make people less hesitant about trying android if and when we have a working ROM.
I talked to TMobile (US), and, while you cannot use an Android device on a Smartphone plan (which is what the HD2 uses), you can switch back and forth, more or less at will, between Android and Smartphone data plans. Knowing this will certainly come in handy when actually trying to connect to the internet.
Personally, I just purchased the HD2, and after using a G1 with Android for a year and a half, I feel like I am going to puke. Why is Winmo such a confusing mess? For some reason I thought it was a mature operating system, but it feels much less polished and stable than Android. Back to the store with it until linux is cracked!
should i sell my nexus one or the htc hd2? hopfully we see android on this thing and i might consider keeping the htc hd2....what u guys think? keep or sell? the hd2 screen makes my nexus one look silly...ha
ok a bit further on .. I managed to find a working (ahem) config for usbnet .. i have managed to ping my leo from my linux box and managed to get a telnet prompt .. The telnet does not fully let me in due to lack of job control i think but for now this is cool ..
Markinus is working on refining this work and making the config default so we can all benefit without the pain ..
for now if you want to see (well my brain dumps and some other output ...

and try the Image, root filesystem and default.txt (and dot-config if your kernel compile inclined)
The shell is crashy and not useful yet ...

Not as far as i have heard ..
i've a questino though @ devs. you said that the kernel is the difficult part... and after that we can easily get linux etc on it? even maemo ?.. since it's based on linux
just wanted to drop in and say hi. unfortunately there's no news yet regarding the freeze problem.
that video is just a joke. some VNC client as they say on the site. as you can see he has winmo screenlock ^^
once we have the kernel problem fixed of course you can run maemo on the hd2.
edit: btw, any datasheet news ?
It's kinda quiet in here since the recent news about WP7S.
Thanx for the update DCordes, can you put into perspective on where about you guys are then?
Is Linux booting?
If so, how is it running?
What hardware are you having problems with?
What hardware is working?
Do you have a projected ET for having Android on the HD2? Even if not finalised, but maybe first Boot?
Thanx
Keep up the good work guys (DCordes, Netripper, Markinus, CR2, Tidsk and the rest of the guys)
Seg
it's actually all in the first post. we have that problem with the kernel freezing and we don't know why yet. that's the big show stopper right now.
except for that the overall situation looks very good! sd card and even usb host is working already ^^
Hi from France,
No idea about the kernel freeze problem ... What should happen after SD card driver being loaded ?
About the multitouch datasheet, I've been searching for it for 2 days, I didn't find anything. I just asked Elan about the release date of this. Waiting for reply ...
Thanks for your work

for me it crashes after init is executed (initrd or extracted to mmc, no difference) or when rootdelay is added in cmdline.

thanks I'm very curiious if somebody will get a reply when I tried the same thing for an aptina camera module they never answered.
with usb host working it's actually not so critical. we could use usb mouse or keyboard until we have a working leo ts driver.

I can't speak for the other devs but I personally never said such things.
Well, the guys that are really actively working on this are written in the first post.
Anyway, Tigerzen, Cass_VM and me, we're working on this with more relax, but we're only active testers and rarely we've helped in the kernel development (if we have).
There are many things working now, but what we really need is a datasheet for our Elan digitizer(/controller) for developing a driver for our touchscreen.
Hoping the best....

Updated 03/14/2012 FrankenTAB v1.1.0
FrankenTAB aims to pick up where the gtab-devs left off with the Froyo based VEGAn-TAB 1.00 b5.1.1 (our v001a is a direct port of b5.1.1 to BL 1.2 with a clemsyn kernel). The current build is a heavily modified Brilliant Corners 1.3.1 base (advanced version of VEGAn-TAB 1.00 b5.1.1), with an overclockable (1.6ghz) & undervoltable kernel from the Clemsyn universal Froyo Skype Fix.
1) This MOD is based on Roebeets' Brilliant Corners ROM for the GTablet. See the description for Brilliant Corners for more info.
2) I am using the latest kernel and WIFI drivers (Skype/SOD/PPP fixes) from Clemsyn, all thanks for the speed of this ROM should go to him.... not me. This ROM is overclockable (to 1.6Ghz) and undervoltable via SetCPU (Get it from XDA if you are a member, or from the market if you want to support the developer)
3) Jcp171, Cobey, and Sharpe351 have been a huge help to me with FrankenTAB. Much thanks goes out to them for their continued help and support.
4) I got the blessing from GoJimi to include the newest version of VTL Launcher in our rom (v1.7.5 - This is NOT on the market yet). I would suggest that you drop in over at http://vegantab.gojimi.com/ to see what's going on with the OFFICIAL VEGAn-TAB ROM, which is based on GINGERBREAD, and show your support for further development of VTL Launcher by purchasing the release version from the Android Market or via a donation on the VT-Labs / VEGAn-TAB website.
INSTALLATION NOTES:
Before attempting to install this ROM, please understand how to use NVFlash (Roebeets thread) to restore your system should something go wrong.
You will ABSOLUTELY need to do a data wipe / factory reset with CWM BEFORE install. I also recommend formatting your sdcard and wiping the dalvik cache before install. my current procedure is:
1) NVFlash to version a 1.2 bootloader base image including CWM
2) Perform my wipes in CWM (data / cache / Dalvik / Format SD)
3) Mount the Tablet via USB from inside CWM / Copy all the needed files to the tablet
4) Install the Rom in CWM
5) Reboot
In more extreme cases a tougher wipe may be necessary:
0) MAKE BACKUPS OF WHAT YOU WANT TO KEEP
1) boot into CWM and format your sd card to 4096/0 then back to 2048/0 (this has cleared some of the problems for some people)
2) format dalvik cache
2a) -skip this step the first time you try, but it may end up being necessary- NVFlash back to a stock 1.2 setup that includes NVFlash (if you are on windows, I posted my NVFlash folder link (HERE) that has a few batch files for stock or CWM recovery)
3) wipe data / factory reset (in CWM)
4) -my method- format /system & /data (by doing this, it basically makes blank, formatted partitions)
4a) wipe dalvik cache again! especially if you let your system fully boot after the NVFlash - CLEAR THAT CRAP OUTTA THERE!!!
5) mount usb and copy over the zip file to the root of your internal sd card (which should be empty after part 1 - if not repeat step 1)
6) install zip from sd card
7) Reboot.
MAJOR RELEASE NOTE: The version 1.1.0 release is a full installation package with a completely new base. As such, please make a backup of your data just in case a full wipe becomes necessary during your upgrade process. I highly recommend a fresh start, but since we are upgrading the kernel, a wipe of the dalvik cache is mandatory at the very least.
APPLICATION COMPATIBILITY: KNOWN ISSUES as of release v1.1.0
(Thanks to Jcp171, Cobey, and EVERYONE for helping work through the app testing):
General Apps:
1. Market: Working properly with the standard market fix... slightly limited before the fix.
2. Skype: working. I have been using it for a while now and it seems to work like a champ.
E-mail:
1. Default E-mail: Works great, but being a non-Gingerbread ROM, Secure Corporate E-Mail setups may not work (Mine does not because of lack of appropriate security suppprt)
File Managers:
1. ES File Manager: Ran fine, was able to give file manager root. UPDATE: You can just long-press the STAR icon to get to the root directory. (THANKS bdds13!)
2. iFileManager: Works fine, but is just a basic file manager. For root access use ES file explorer or root explorer.
Utilities:
1. Anreboot: Fine for reboots, but DO NOT USE THIS TO REBOOT INTO RECOVERY. It will likely only ever reboot into recovery forcing you to NVFlash the device to get it working again.
Games:
1. Plants Vs Zombies: (Doesn't work)Loaded and got all the way into the first level but quickly crashed. Will crash at some point either loading or trying to play. At the most it's extremely unstable...
2. Gem Spinner II: Not functional
3. Game compatibility with several games improved (Cut the rope now works) by removing the undervolt and returning voltages to default levels (still at 1.6ghz). May vary tab to tab... (Note: Even lowering the speed to 1ghz did not change Plants vs Zombies or Gem Spinners non-functional statuses...)
Any other apps we tested worked. Please let us know if you find an app with a problem and we can make sure to confirm the issue to help Pix out.

Clemsyn has asked us to test his latest kernel build for froyo with SOD protection, Skype fix, and PPP support. Grab the download and let the testing begin. If it goes well I will incorporate it into the v1.1.0 release of FrankenTAB. UPDATE 02/08/2012 - This will be the new default kernel in the v1.1.0 release - all tests confirm this to be an excellent release from clemsyn.
Grab FrankenTABv001a from HERE
- v001a is based on VeganTAB 5.1.1 just ported to the 1.2 BL with clemsyns kernel and a market update. (Still seems to be fairly popular - I will continue to support v001a as best I can for those looking for the classic VEGAN experience on the 1.2 boot loader.)
SCREENSHOTS:
Work is coming along good on v1.0.2. I hope to have a release ready this weekend. This release will be very minor tweaks to some icons and graphics that were not receiving a lot of love from the community, along with some tweaks to the build prop.
In the next phase of testing I will be looking at kernel options including support for ppp in the default kernel, along with the possibility of an optional kernel or kernels. (will be v1.1.0)
Anyone that wants to test v1.0.2 I have uploaded a testers update HERE please be detailed in reporting any problems or new successes that are found.
Cool does camera or google talk work with camera?
Is this the full ? : FrankenTABv100.zip or is it this one FrankenTABv100RC1-full-install.zip
Thanks cant wait to try it
P.s Oh NVM i see its 2.2 none of the new Google apps will work thanks
Version 100 is the latest full file. version 100rc1 is the older release candidate.
no PPP support
Same like other ROM with clemsyn kernel
I try to use pppd (pppd /dev/rfcomm0 call xxx) but got message below
pppd: This system lacks kernel support for PPP. This could be because
the PPP kernel module could not be loaded, or because PPP was not
included in the kernel configuration. If PPP was included as a
module, try `/sbin/modprobe -v ppp'. If that fails, check that
ppp.o exists in /lib/modules/`uname -r`/net.
See README.linux file in the ppp distribution for more details.
Any chance to compile kernel with PPP support ??
I can ask clem to compile me a custom kernel, but it may take a lil while. I had planned to ask for something custom from him anyway so I will toss that in too. I will post an update in the second post when I hear from him, so keep an eye out.
I have been running this since 1.0.0 and love it. This is the ROM I have settled on. After trying Gingerbread and HC, I came back to Froyo for estability and speed. Love the icons on the status bar (Home, back, menu). All acceleration works including HD video. Like I said, very smooth and stable. All the games also work with it.
Netflix, Flash, Skype work.
Just loaded up over flashback, no problems here. Running so great!!!
Sent from my SGH-T959 using xda premium
Excellent ROM
Love it!
I love it!
Are you considering changing the icons to ICS themed icons?
I may look into it for a future release, but right now I have to post the update (v1.0.2 is live) and try to confirm that, with the new kernel that clemsyn compiled for us, SOD issues are solved and SKYPE IS WORKING PROPERLY!!
watch the OP in the next few mins for the updates and details!!

why the hell i can't boot any rom , after installing flashback 10.3 ?!
You should NVFlash back to stock, and then try to install. Thats the best help I can give with the information you have provided.
Good luck. If that doesnt do the trick, let us know and we can try to work through it.

So far the ROM is great. I came from brilliant corners. My only issue is sometimes with flash, it's all blocky and distorted like a messed up NES cartridge.sound is fine.i fix it by full screening the flash video or changing the resolution, then back. Also, is there a DSP manager, or sound booster working in this ROM (for speakers, not headphones?) Thanks
Wifi can sleep when screen turns off?
Using 1.02 update, I notice also wifi never goes to sleep eventhough
I have setup wifi sleep when screen turn of in wifi sleep policy
Anybody experience the same?

Hi,
I did some experimenting with getting kernel serial console output on SGSII I9100 without soldering, or even disasembling the device. And seems I succeeded .
So, for anyone interested, here are the details.
First, two warnings:
- you will loose access to CWM recovery! ODIN still usable though.
- no access to bootloader output, only kernel logging available
Now the steps:
enable UART PDA
Flash original samsung ROM (changes in service mode settings in cyanogenmod are not permanent for some reason, I haven't tried other ROMs)
Enter service mode by dialing *#7284#, select UART mode PDA (default is modem. No need to change USB mode to PDA, leave it as is).
Configure, build and flash the kernel
get your kernel command line using dmesg right after boot
modify the console parameter to console=ttySAC2,115200
configure your kernel with this command line (CONFIG_CMDLINE). In my case, the commandline used was:
Code:
loglevel=4 console=ttySAC2,115200 sec_debug.enable=0 sec_debug.enable_user=0 c1_watchdog.sec_pet=5 [email protected] s3cfb.bootloaderfb=0x5ec00000 ld9040.get_lcdtype=0x2 consoleblank=0 lpj=3981312 vmalloc=144m
set force override parameters passed by the bootloader (CONFIG_CMDLINE_FORCE=y)
build the kernel
build your ROM of choice (I have used cyanogenmod) with this new kernel
flash
power off the device, connect "standard" Samsung UART cable - microUSB with 523K resistor to ID pin, 3.3V to RS232 level converter
Now the phone should start and you should see kernel boot messages on connected terminal emulator.
Open questions:
Why UART switch changes are not permanent from cyanogenmod? Is this i known bug?
How to change bootloader parameters from within linux? E.g. kernel command line options... Does anyone know where are the persistent settings of the bootloader stored?
This information is mainly collected from many sources here on this forum, thanks to all of you for publishing your findings. I take credit only for putting all this information together and spending a lot of time trying it out . Also, I take no responsibility for any bricked devices, make sure you know what you are doing, before you start following my steps.
Hope this helps anyone .

The only reason I see for this is kernel. Are you using CM7 or CM9 ?
What did you use as UART cable? Do you have a microUSB to RJ45 + Z3X, or some homemade all-in-one ?
I am using CM7.2RC0 KANG, updated yesterday. Kernel also latest git, home built. But I remember having this problem with "official" nightly builds as well.
For cable, I have my own micro USB with id pin on break out cable, so I can switch resistors, and home made level shifter made from a MAX chip, that connected via stock USB to serial to the PC.

More details on this? - is that what changes UART PDA?
For the kernel cmdline side of things - I have never found any way to override the kernel cmdline in a controllable manner. The bootloader has a fixed commandline, and it makes changes to it depending on what buttons are pressed (which is why you can't enter CWM via the button combos if you force the cmdline) However, if you're working with a custom kernel, you can just go find the handler for the console= option and force it to always be ttySAC2 regardless of what is passed in the source. This won't work for custom kernels. (Wait... neither will the OP's approach either, sorry - not enough caffeine yet.)
If there's another cmdline option you want enabled, you can overload one of the ones that is in use, and have it trigger other handlers (but those have to have their parameters hardcoded) - such as how garyd9 caused ramconsole setup to be triggered by the loglevel cmdline parameter at https://github.com/garyd9/linux_kernel_GT-P6210/commit/d796ac86dcff1eeda19d7638315dcf6fe3978318. If you're wondering why he did this to enable ramconsole - in the I777 and GT-P6210 source drops, ramconsole support seems to be improved compared to the I9100 source drops - it requires little to no extra patching AND it's controllable by the kernel cmdline - while that's normally an improvement, it's a pain in the ass if you can't change the bootloader to add the ramconsole cmdline parameters.

Never heard of this file before, now took a look and it looks very interesting. I will investigate this option further, thanks for the hint.

For the kernel cmdline side of things - I have never found any way to override the kernel cmdline in a controllable manner. The bootloader has a fixed commandline, and it makes changes to it depending on what buttons are pressed (which is why you can't enter CWM via the button combos if you force the cmdline) However, if you're working with a custom kernel, you can just go find the handler for the console= option and force it to always be ttySAC2 regardless of what is passed in the source.

Yes, I agree that your approach is also usable. Advantage of your way is that you are not loosing CWM and such. Mine is that it's without ugly hacks in the kernel ;-).
Ultimate goal would be to modify the bootloader parameters, so kernel recompilation is not needed at all, but not sure it is possible - thats my next direction of research .

Sorry, not following you here. Custom kernel - you mean kernels compiled by third party, which we can't modify? Well, not sure you need a log for kernel you can't modify, maybe for bug reporting to original author? If the kernel works, you can get most of the log using dmesg... And I am not interested in binary-only kernels...
Entropy512 said:
If there's another cmdline option you want enabled, you can overload one of the ones that is in use, and have it trigger other handlers (but those have to have their parameters hardcoded) - such as how garyd9 caused ramconsole setup to be triggered by the loglevel cmdline parameter at github.com commit d796ac86dcff1eeda19d7638315dcf6fe3978318. If you're wondering why he did this to enable ramconsole - in the I777 and GT-P6210 source drops, ramconsole support seems to be improved compared to the I9100 source drops - it requires little to no extra patching AND it's controllable by the kernel cmdline - while that's normally an improvement, it's a pain in the ass if you can't change the bootloader to add the ramconsole cmdline parameters.

Maybe that's a better solution for a kernel distributed to users and such. What I was trying to achieve is to have serial log of a booting kernel so you can troubleshoot kernel which does not boot, or which hard-locks or oops. AFAIK, ram console is useless in such cases (correct me if I am wrong, I have very little experience with ram console).
As far as I am interested, the description above does exactly what I need .

That was a brainfart - meant it won't work with stock kernels!
The ramconsole approach was just meant as an example - but instead of hooking loglevel to do ramconsole stuff, you could hook it to do other stuff. Of course here, since there's already a serial cmdline entry but it's just wrong, it's easy to just override.
As an example, I abused the "overload the loglevel handler" trick to try and enable profiling. (However, profiling didn't let me get any info on which interrupt handler is eating our IRQ time on suspend/resume.)
Just for reference, here is the cable I am using. There is a stock prolific PL-2303 based USB to serial converter (the grey cable), then a RS232 to 3.3V TTL level shifter (home made, built into the DB9 conector), and then there is a stock micro USB cable. The connection between these two is on this connector for easy re-configuration, as I am using the level shifter for other purposes as well.
The micro USB cable is stock microUSB to USB-A, but I cut off one end to connect it to the level shifter, and I have also cut the micro USB conector to connect a cable to the ID pin. That one and ground are on the blue/white cable, for easy resistor switching.
Except for the ID resistor (523K according to the table, some 507K in my case), all electronic parts are SMD .
A good source for USB-to-TTL/LVTTL cables is FTDI - they sell FT232-based cables. Adafruit is a good vendor for these in the USA.
Just noticed you can get bootloader output by booting the phone and shortly pressing Volume Down (shortly so that it doesn't boot into Download mode). I did it by accident and saw some Samsung PBL logging on my screen.

Cool. If you can get the bootloader prompt, we are maybe a step closer to being able to even unbrick phones .
So far, I was not able to reproduce this, can you, please, describe better the steps? Also, what version of bootloader do you use?
I did it once by accident, I haven't retried. Basically when I booted phone I mistakenly pressed the Volume Down button with the Power button, but not long enough to make it boot in download mode.
I'm not sure which bootloader I'm running, I think it is some LPx one (if flashing KI4 PDA doesn't overwrite it).
Here's the log of it:
http://pastie.org/3544766
Following up on Odia's hint (thanks ), I decoded the structure of the params.blk file and wrote an utility to deal with it. The file contains parameters normally visible in SBL. With this utility, you can manipulate then from within normally booted phone.
Run it without parameters, it will display current values for all parameters. With parameter name (case insensitive), it will display just that one parameter, run it with param name and value, it will set the new value.
WARNING: no checking on validity of the values is done. If you brick or fry your phone, I take no responsibility and it is your brick!
Put the utility somewhere where you can execute it, e.g. /data. Then to set e.g. a kernel command line to start logging on console, issue:
sblparam command_line "loglevel=4 console=ttySAC2,115200"
From my experiments it looks like the SWITCH_SEL parameter is ignored by the HW, at least I haven't observed any real effect. But you can change the UART switch by modifying a file next to the param.blk, /mnt/.lfs/sw_sel. It contains an ASCII number, by default 1. That is modem uart. Change it to 3 to get PDA uart connected, by e.g. "echo -n 3 > /mnt/.lfs/sw_sel".
Please, be careful about files in /mnt/.lfs, the j4fs is a strange filesystem. You can create files there, but you can't delete them. If you grow a file, you can't trim it back down. I tried longer numbers in sw_sel, and I broke the output completely, and I had to restore the whole .lfs partititon from backup (which reminds me - do a backup first , e.g. with dd).
Now there is no need to flash samsung firmware or compile custom kernel to get kernel console anymore! .
EPIC WIN!!!
This is going to be very nice.
This is amazingly cool!!! Maybe we can get even more...

My kernel finally boots
Seems like I get everytime the bootloader output by booting the phone with Power + Vol Down while having UART cable plugged in, then releasing the buttons when log starts to appear to make it not go into Download mode.

Hmmm, must be really something with your kernel. I was not able to get any bootloader messages, and my unit always turn on as soon as I insert the cable.
AFAIK, the resistor is "read" and attach interrupt asserted by the FSA9280 switch. So it looks like your kernel "programs" the switch not to wake up the CPU? Maybe the switch has interrupt assert masked out? I will check the switch sources, when I get some time, maybe I find something interesting...

I'm wondering if maybe he uses a different resistor value than you do. If I recall, there were multiple values that could trigger UART mode.
The difference in behavior being seen goes earlier in the boot process than kernel boot.

No, he does not (apart from the fact that no two resistors are exactly the same ;-) ). I know, because I made both cables ;-).
Moreover, I tried couple of different resistor values, and found none which would not trigger the boot on my unit. You can get e.g. car mode active together with UART with slightly different resistor, but AFAIK, you can not prevent the boot trigger.

Yes, for sure. But don't forget that "turning off" the phone does not mean all ICs in the phone are really powered off. E.g. the switch IC is, AFAIK, always on (unless you pull the battery). So you can set the interrupt mask in the switch and then turn off the main CPU. When UART cable is detected by the switch, it uses the mask to trigger or not trigger interrupt to the CPU.
Which brings another idea - XpLoDWilD, can you, please, try pulling out the battery, put it back and then connect the cable? The switch does not have any means of persistent storage, according to the spec sheet, so if there is no hidden easter egg, then the cable should trigger boot in this case, I believe.
Rom (Ice Cream Sandwich):
A Near stock image, modified for a clean root, busybox install
ezAcer_AV041_A500_1.31.00_WW_GEN1_RootBusybox_S.zip
(MD5: 7e9fe5642b6e082fb4382288337d8dfa)
The long overdue update to my previous Honeycomb rom
==~== Requirements ==~==
This rom requires the unlocked ICS bootloader, I also recommend my A500 Public Recovery, however all recoverys patched for the new bootloader ought to allow installation of the rom.
Bootloader install instructions are: here thanks to civato. Note for step 4 simply ensure my update zip above is either in on the device instead of the ones listed. Note instructions below before actually flashing the rom.
Additional information can be found at Skrilax_CZ's bootloader development thread here
And my A500 Public Recovery development thread here
==~== Installing ==~==
Once you have the new bootloader and ICS recovery installed (again preferably the A500 Public Recovery but any ought to work)
Cleaning your tablet:
If you are attempting to upgrade the tablet without wiping (and there is no need to wipe if you are currently running my acer7.014.14 rooted image
Select "cleanup tab" in the main menu of the A500 Public Recovery
(If you are using another recovery, select the options for a. Wipe Cache, b. Wipe Dalvik Cache, and c. Fix Permissions)
Install the rom:
Select "install zip from sdcard" and navigate to ezAcer_AV041_A500_1.31.00_WW_GEN1_RootBusybox_S.zip
Thats it
==~== Root ==~==
Applications are granted Superuser access from ChainsDD's Superuser.apk as usual (a request asking you will appear when an application requests root, and permissions granted before the upgrade may still be active post upgrade)
adb shell: ADB by default will not have root access here you have the following options:
> if you run 'adb root' all adb operations will have root until reboot (aka 'adb shell' and 'adb remount')
> If you have a non-root 'adb shell' you can switch to root with the 'su' command
> If you wish to restore the permanent adb root on boot add the following line to the build.prop 'service.adb.root=1' this will force the old behavior of root always via adb without using the 'adb root' command.
This change has been made as its a little more secure, (However obviously still lets anyone with access to the USB port access to all the tablets data)
==~== Features ==~==
This rom is intended for users that wish a nearly stock system configuration, however either need root and busybox, or enjoy conducting more advanced tasks at the command line and wish a smooth root experience.
In addition some other small mini-fixes have been applied to the image in hope of a smooth experience.
Here is a list of the features and changes in the rom
Modified ADB to allow adb root to operate without changing the production build properties
Kernel patched to allow system remount
Busybox built from CM9 source tree and integrated into the rom
runparts (ie /system/etc/init.d functionality)
GPS lto fix thanks to waydownsouth
FDUpdater (ie system update) removed to not be prompt for an update you can't install.. if you want it the original app is in the system folder of the update.zip, (FDUpdater.apk) its not odexed so install normally)
Kernel modules md4.ko sha512_generic.ko and cifs.ko added to the rom (md4/sha512 is loaded on boot via an init.d script, users of cifs need to check the "Load cifs module" option in CifsManager.
Added Superuser
DHCP Infinite Lease bugfix (why has google not fixed this) applied as a patch to the framework.odex
Rom is still odexed (and I re-odexed the one changed odex for the DHCP patch)
Developers wanting more details or the source to anything I changed can see this detailed modification guide: http://pastebin.com/ApUjMDJ7
Note to anyone wishing to make a modification to the rom they are flashing, everything in the system folder of the update.zip is unchanged from the original rom. (when flashed the system is patched and augmented via various files and tools in the custom directory, also the boot image is pre-patched)
==~== Extras and Addons ==~==
** Overclocked test kernel: See my ezT20 kernel here (previously OCTestV3 here
(kernel last updated June 18th 2012)
** Disk IO enhancement: significantly increase diskio scores, and make the table slightly more responsive when reading/writing to flash: On this post

==~== Tips and Tricks ==~==
This section is where I try to explain how to get the most of your tablet, and solutions to common complaints due to changes between versions.
-----) Rom "Bloat" (------
First half of what people call rom bloat is not quite true, (there is such a thing, and problems related to it)
Our tablets have 590MB system partition, a 97MB vendor partition, a 1GB cache partition, and the rest of your tablets space in a data partition (mine is 27GB, but if you have a smaller tablet model it will be less) All roms will have currently the same split between the partitions.
Its only that last partition that contains your data, the system/vendor partitions are by default read only, and the cache partition is temporary data.
System apps are on the two read only partitions, thus removing them for the most part will not cause more data to be available to your apps. Also this is storage space so having more "free" will not speed up your device (well as long as we are not too close to full.. and this rom is not)
Most of these apps play nice, they don't run unless you select them thus you can ignore they are on your tablet and all will be just as fast as if they were never installed
There is however one *Problem* Applications pre-installed that run constantly in the background that you the user are not interested in.
Solution: Freezing apps
* Goto Settings-> Apps-> All
* For any of the following that you do not use:
> Photo Browser 3D
> SocialJogger
> Acer Media
Select the app,
Choose Disable
Clear Data
If you use the app, obviously keep it enabled, also you can return to this screen and re-enable the app.
-----) Screen flickering/brightness oddities (------
I have had some brightness issues initially, simple fix was to go into settings->display->brightness uncheck auto bightness, lower the meter, and re-check auto brightness
-----) Sluggish system (------
Make sure on first boot you give the system some time (2h/3h after upgrading or re-installing where there is a large collection of media on the tablet) before measuring speed, as the system may be still sorting/indexing tablet data and will speed up when done.
Also while apps are installing the system may behave slower (if you have many market updates happening in the background)
Otherwise check running processes in settings to see if anything may be slowing down your tablet in the background (Settings -> Apps -> Running)

Overclocked kernel [May 23rd 2012]
(wow I think we can hear crickets in here..)
Anyway using the now released source code from acer, and richardtrip's OC patches from HC I now have an overclocked kernel.
As of V3 I also have the voltage controls patched up from richardtrip's kernel.
[size=+2]AcerOCTestV3_S.zip[/size]
MD5: 6907e7585fedf534261cc8ebe23d824a
Instructions are simple: flash from recovery
Links to the github source and other information on the AcerOCTest kernels is in this related notecard
While I've only tested it on this rom, the installer is using koush's anykernel logic (or one of my own flavors of that logic anyway) and thus this ought to cleanly install on any rom based on the stock ICS kernel regardless of the tweaks the rom creator may have added.)
Also I've not had much time to test so let me know if there are issues
----
List of all versions:
V3 - AcerOCTestV3_S.zip (md5: 6907e7585fedf534261cc8ebe23d824a) May 23rd 2012
V2 - AcerOCTestV2_S.zip (md5: da01a90dda3916ec55ebb62bbb1164f1) May 22rd 2012
V1 - no public binary (caused reboots on tablet sleep)
Just tried the OC kernel on Civato's latest rom and it does work. Can't go over 1.2ghz without a reboot, but that extra bit of speed is nice.

what dosn't work? >1.2ghz or flashing it on Civato's rom
the rom ought to work, it extracts the current boot.img, swaps the zImage (leaves the ramdisk) and swaps the modules in /system/lib/modules.
as for the speed.. your device is intended for 1.0ghz any thing extra is a bonus.. the kernel thus boots at 1.0
edit: although I'll look into it some may be a new verification in the updated kernel. the tegra2 OC logic is much more complicated than the msm logic I'm used to on the HTC dream.. I'm more worried about reboot-on-wake bugs I had in earlier revisions

looking closer its a but..
So now I have two OC tests I've made.. the first one I didn't publish because while it could go > 1.2 it crashed when you put the tab to sleep. (at least when USB wasn't connected)
This one crashes when you go over 1.2.
maybe if a combine them I can get something that works...
Perhaps a slight voltage bump is needed to get beyond 1.2? In either case, 1.2ghz feels leaps and bounds faster than 1ghz using this rom. I'm starting to feel like we don't even need cyanogenmod 9 for the a500.

No.. well maybe but you not getting that far.. its a kernel BUG condition, meaning some code found some invalid input and refused to process it, instead triggered a reboot.. looking at the diff of mycode and the code in the CM thread.. no logic is different so i'll need to poke min/max rail voltages. (still sorting out all the voltages and CPU speeds.. the dream had it all in one large table .. here it seems spread out in various places between two files..)
(I'll also try to include the voltage manipulation patches just making sure things are stable first thus 1.2ghz is a better testing speed for me than trying to Max my device)
As for CM..it seems to have many interesting features.. but at some point I'm not sure its direction matches my interests.. (maybe its just become too much of a kitchen sink i don't know, that or too much now in aosp) I'm sure to look at it but probably start an aosp build with cherrypicked features I like.. until then this tweaked ics rom will need to do.
Fyi I haven't had a single issue on your kernel.
Been waiting on this! Thanks ezterry.

Well next version will have voltage controls and working higher overclock speeds
(just ironing out some minor issues with the voltage control)
Some side info and feedback I get from some users that are on ICS bootloader and still getting SoD
I made a boot.img with in the "boot.img-ramdisk" / postboot.sh = I deleted the following line
"echo 7> /sys/module/wakelock/parameters/debug_mask" and it solves the SoD problem some still have when they are on ICS bootloader.
Just had a other pm today confirming it worked.
And I'm testing your modules and OC zImage with this modded in the boot.img-ramdisk (and my other tweaks) and I don't get any SoD , screen off , back on no problem.
Also confirming 1200 is max , over that it will reboot.
Ezterry,
Thanks!
very nice kernel, I flashed the 'civato' version to avoid SOD ...
Works nicely in 1.2 Ghz...
Btw, the old "No-Frills CPU control" apk doesn't apply the upper 1.2 Ghz frequency at Boot as asked.
Do you know another tool working to apply OC at boot?
(I'm using Civato's last version of flexreaper ROM)

.. I think this solution has nothing to do with the debug variable and everything to do with *forcing* the user to install a ICS kernel and stop messing around with the HC kernel they had earlier. (since you are installing a new boot.img)
So says the code anyway. If you want to prove it wrong after the crash + quick reboot get your users to dump the last_kmsg and output of dmesg so we can actually debug what is going on.. well unless its just the wrong kernel
But if the "obecalp" works to get some your users to install the right thing and so they fix there own problem.. so be it.
--
I have to inform users of my rom its no longer my rom if they install one of your (or anyone else's) full boot images and not to complain of any resulting bugs here.. If anyone with this rom has a SoD (none reported yet.. but I block installation on the old HC bootloader) let us know if you have such an issue. (just want to add if the full boot image was modified from the one in this rom, and intended for users of this rom that isn't an issue.. the issue is when its for another rom)
Its a bit different when you flash my update on another rom, since I only swap the kernel and leave the ramdisk as is, (by unpacking and repacking the boot.img) the rom designers changes stay intact.. well unless they had a kernel module that I've not included.. but even then we will need to re-build that module)
and you can test this after boot enter terminal and run echo '3> /sys/module/wakelock/parameters/debug_mask' that is the default.
(If it is disabled it just won't print the list of wakelocks to the kernel log on suspend..)

Hopefully fixed the max speed bug, and added in the voltage controls.
Not much else yet has changed. but seems stable.
Its the same anykernel package as last time so it should cleanly swap the kernel (leaving the previous ram disk) for any ICS stock kernel based rom.
(Is there one app out there that actually knows how to successfully set *both* cores frequency and set voltage on boot, without giving the world access to the /sys files [so a malicious app cant overclock+fry the device or under clock it so it feels painfully slow]... soon I'll just write an init.d script for myself to echo the values directly into the kernel settings /rant)
I use setcpu.

I don't like that he (and has always) granted global write permissions to the /sys/ files controlling the CPU/Voltage settings .. and it was acting flaky on voltage settings on boot.
Voltage Control looked good until a verification in /sys indicated if left the second CPU core at 1GHz
Now poking system tuner/system tuner pro.. many interesting features. Not sure they quite understand use root to write the value.. or set the file to your own ownership..
*ANYWAY*
you can check these yourself manually at the command line/adb shell:
CPU0: /sys/devices/system/cpu/cpu0/cpufreq
CPU1: /sys/devices/system/cpu/cpu1/cpufreq
current status of the voltages is in the readonly: frequency_voltage_table
list readonly of available frequencies is: scaling_available_frequencies
list readonly of available governors: scaling_available_governors
the current min frequency: scaling_min_freq
the current max frequenct: scaling_max_freq
the current cpu governor: scaling_governor
the current undervolt levels (negative values are over volting): UV_mV_table
UV_mV_table is in the same order as frequency_voltage_table, and if written to with the same number of values will update the voltage levels.
I got a question , why :
sha512_generic.ko = what does this do ?
modules.order = why does it need to know the order ?

The UNOFFICIAL LineageOS 17.1 T550 ROM
BACKUP YOUR DATA AND OLD ROM BEFORE trying my rom.
Let me be clear, I have the SM-P550, NOT the SM-T550.
So I built a SM-P550 rom which is almost the same as the SM-T550 except the "P" stands for Pen.
I believe my P550 rom with minor modifications will work on the T550, but I have no T550 to test it on. I believe it will work because I have used virsys T550 rom on my P550 and it works, but the X-axis touch is inverted.
So I built SM-P550 with code to fix the X-axis touch inverted problem and it's one of line code. If I leave that one line of code out, then the X-axis will be correct for the T550. I have tested my 17.1 T550 rom on my P550 and it works, but again with the X-axis inverted. Just remember I don't have a T550 to test it on so you may run into bootloops, stuck at boot animation, etc.
If you are NOT an expert in using fastboot, adb, odin, heimdall, twrp, DO NOT attempt this ROM. You must know how to use these tools to revert back to your old rom. I'm not a Windows user so do not expect any help from me. My main OS is Lubuntu 20.04 LTS and all my roms are built on this platform.
If you are new to flashing custom roms, do NOT attempt this.
If you need your tablet for work and something important, do NOT flash this rom. This rom could result in a bricked device or boot loop or non booting device or you not being able to revert back to your old rom.
Again, the T550 rom that I built does boot and function on my P550, but I have no T550 to verify.
BACKUP YOUR DATA AND OLD ROM BEFORE trying my rom.
The rom has the latest monthly 2021 security patches.

What doesn't work
1. LineageOS FM Radio app does not work. The P550 and T550 don't have the LTE chipset for it to work.
2. The stock Jelly browser crashes a lot. Use a different browser. There's lots of better options that are more stable and reliable than the built in Jelly browser.
3. Home screen text may look fuzzy.
Text on home screen looks funny/fuzzy. This only seems to affect the home screen and nowhere else. I have seen the same problem on the SM-T350, SM-T560NU, SM-P550 and Nexus 7 2013.
Problem is with stock trebuchet launcher and/or its fonts. I tried rootless pixel launcher from fdroid as a quick and simple test and see no problems with home screen text. Rootless pixel uses a different font though. A future LineageOS update could resolve the problem?
FAQ - I spent hundreds of hours building this rom. The least you can do is spend a few minutes reading everything before posting.
Q1) Why are you releasing a ROM for a tablet that you do not own?
A1) I don't own the SM-T550, but have the SM-P550. I also build roms for the SM-T350 and SM-T560NU. All these platforms use the same msm8916 code base. As such, all my work from the SM-T350, SM-T560NU and SM-P550 could possibly benefit SM-T550 users. For one P550 owner, there are probably twenty T550 owners.
Q2) What if my app, xyz, doesn't work?
A2) I won't answer questions regarding why your app doesn't work. If your app, whatever it is, doesn't work, then go back to your old rom. It's difficult enough building and maintaining these roms. Remember, I'm an unpaid volunteer making a rom for free for your benefit, not mine as I don't even have the T550.
Q3) Your rom is laggy and buggy.
A3) If you find the above, then go back to your old rom. There's only so much software can do on a 2015 budget level tablet. Remember a budget tablet will have the slower SoC/CPU and less DRAM than a top of the line model. Your tablet will also run slower when you use gapps (google apps). You can run a lot of software without using gapps. Research newpipe, microg, youtube vanced, aurora store etc.
Q4) What TWRP should I use?
A4) Use 3.4.0.0. Get it at
Download TWRP for gt510wifi
Download TWRP Open Recovery for gt510wifi
dl.twrp.me
Q5) Why should I use this rom?
A5) You don't. I only offer it because I have built the SM-P550 and it was an easy change to make a SM-T550 rom. If you don't like this rom, then don't use it. Yes, it's that simple.
Q6) Can you build SM-T555 (LTE) or a crDroid version of the SM-T550?
A6) No. All the source code is open source and my changes are in the repo diff file. You can use these two with the roomservice.xml to build your own rom.
Q7) Will you offer monthly updates with security patches?
A7) That all depends on if I continue to have high speed Internet and on the reaction of the posts in this thread. If people are going to complain, then I have NO incentive to make an update. Remember, I don't have the T550 so I get zero benefit from making this rom for myself.
Q8) Can you help me? I'm a newbie. Can you provide step by step instructions?
A8) There are lots of tutorials, videos, etc on how to flash roms. Do your own research.
Q9) Can I report a bug with respect to the rom?
A9) Yes, but you need to supply a) how to recreate it b) a logcat c) a github commit showing how it was fixed. Even then, if I don't have the means to recreate it, I won't be working on it.
Q10) Can I build this rom? Where are the source and kernel source files?
A10) Yes. The kernel source files are at
Samsung MSM8916 Devices
Samsung MSM8916 Devices has 68 repositories available. Follow their code on GitHub.
github.com
aala27 - Repositories
aala27 has 7 repositories available. Follow their code on GitHub.

Q11) Okay, I understand the consequences and that this is beta rom and willing to take the risks outlined, now where can I find the rom?

Hi rretiredtab
I have a T550 with the latest virsys image 16.0 from March 2020.
It is more or less stable, but I think, it will be always slowlier. Empty dalvic and cache does not help.
I'm ready for a new challenge. If I can help you, please let me know.
Best regards
Schaagi
Hi retiredtab,
I ready to try this rom

My 16.0 rom for the SM-P550 is based on virsys repos. However, I was only able to make 2 builds using his repos before a LineageOS update in Sept 2020 caused it to get stuck at the boot animation.
Then I tried virsys 17.1 repo and it too gets stuck at the boot animation. I know virsys built crDroid Android 10 rom and uploaded it sometime June 2020, but his Android 10 repos on github are dated March 2020 so whatever patches he did to get crDroid working isn't on github.
I don't know if 17.1 will be faster than 16.0. The 17.1 builds, by default, use an overclocked CPU and GPU in the kernel code. However, I don't know if you will see any real world differences in performance from the overclocking.
In addition, I don't know if virsys March 16.0 March 2020 is overclocked or not. You can always download an utility like CPUinfo at
CPU Info | F-Droid - Free and Open Source Android App Repository
Information about device hardware and software
f-droid.org
to see if the CPU is running at 1.2Ghz or 1.6Ghz (overclocked).
@Schaagi and @Simone101, please let me know if the T550 ROM boots or not after you have installed it. I'm pretty sure it will, but would like to know ASAP.
Then, afterwards, you can let me know how it works over a 24 to 48 hour period. I'm interested to see if it randomly reboots or crashes.
As for speed and performance, just remember it's a 5 year old entry level tablet and unless LineageOS is written in assembler language, it will never match a top of the line model tablet.
Thank you.
I've installed your image as clean-install. It boots !!!
At the beginning of the setup process there is a bluetooth error, that repeats after every new boot.
First installation without opengapps -ok
Second one with opengapps - ok
Restore Data from previous image - ok
As next I will try to install magisk.
Wow, good job. I will check it for the next days and give feedback later.
Best regards

Can you provide a screenshot of the error please?
I haven't seen the bluetooth error before on my SM-P550 and I reboot my SM-P550 a lot because I'm always flashing new builds.
I don't use bluetooth at all, but when I turn it on, I can see my neighbor's 65 inch TV. Also, I can pair two tablets together using bluetooth.
Meanwhile I have installed Magisk 21.1 and it works too
I've attached 2 screenshots from Bluetooth error.

The above is why we need BETA testers.
Okay, I ran into the bluetooth error problem on the SM-T350 and it was due to a missing bluetooth library.
In my SM-T350, I have
Code:
# RT 17.1 copy bluetooth file otherwise bluetooth keeps crashing
PRODUCT_COPY_FILES += \
vendor/samsung/msm8916-common/proprietary/vendor/lib/libbtnv.so:$(TARGET_COPY_OUT_VENDOR)/lib/libbtnv.so
Those 3 lines of code are not in the T550 build. It's easy to add and I can create another BETA build. It's building right now and probably be done in the next 2 hours or so.
If you want to add the libbtnv.so file yourself, here are the instructions
1) Boot into TWRP 3.4.0.0.
2) Click Mount. Choose System.
3) On your computer, goto
proprietary_vendor_samsung/libbtnv.so at lineage-17.1 · Galaxy-MSM8916/proprietary_vendor_samsung
proprietary_vendor_samsung. Contribute to Galaxy-MSM8916/proprietary_vendor_samsung development by creating an account on GitHub.
github.com
4) Click download.
5) Goto the directory where the libbtnv.so is saved.
6) Plug in microusb cable to tablet.
7) Then use adb to push the file using the command
Code:
$ adb push libbtnv.so /system/vendor/lib/libbtnv.so
libbtnv.so: 1 file pushed, 0 skipped. 48.5 MB/s (16128 bytes in 0.000s)
8) Check to make sure file was pushed.
Code:
$ adb shell ls -al /system/vendor/lib/libbtnv.so
-rw-r--r-- 1 root root 16128 Dec 19 21:24 /system/vendor/lib/libbtnv.so
9) Reboot into system and bluetooth error should be gone.
OR
Just wait until my next build is done to get rid of the bluetooth errors. I'm confident the error is due to the missing bluetooth library file.
I will send you and Simone101 a PM when the new build is done.
The new BETA build is finished, but having problems uploading to host server right now. I will try again in a couple of hours to upload. I will PM when I get it uploaded.
I've installed the new image and bluetooth error has gone.But I'didn't test the functionality of bluetooth at the moment.
Will check more in detail and inform you about the results. Thank you.

Schaagi

I want to test your ROM , where I can download it.
At the moment I use the cdroid 10 by virsys
My CPU runs at performance mode with 1600 MHz.

Over at the T550 thread, it seems that some people who are using crDroid 10 are reporting
1) camera not working
2) brightness not working
3) browser crash (that's you)
#1 and #2 work on my build. As for #3, if you are using the built in Jelly browser, I have noticed that if you open more than 4 windows, it crashes sometimes.
While not perfect, I found that smartcookieweb app works better than Jelly.

The Brave browser seems to work the most reliable. You can use Aurora store to download it from play store or try downloading brave apk somewhere.
On a daily basis, I use smartcookieweb as it has built in adblocker and suits my daily browsing needs.
@retiredtab
Both cameras works on Cdroid for me.
Yes, browsers crashes after some times, I use opera mini.
Bluetooth works for, tested sending and recive images.
GPS is not working, will try it again next time.
Magisk 21 works.
WiFi works.
Hi retiredtab,
Nice to see that anybody has try to give us an update for this fossile
Please let me knoe where can I download and test your build.
regards,

GPS is not working
Click to expand...

No need to retest GPS. I already know what's wrong. This is the same problem I had with the T350.
The T550 build is missing the commands
Code:
# GPS
PRODUCT_COPY_FILES += \
vendor/samsung/msm8916-common/proprietary/lib/libloc_api_v02.so:$(TARGET_COPY_OUT_VENDOR)/lib/libloc_api_v02.so \
vendor/samsung/msm8916-common/proprietary/lib/libloc_ds_api.so:$(TARGET_COPY_OUT_VENDOR)/lib/libloc_ds_api.so
Now I did test the T550 build on my P550, but it looks like when I made the final image, some of my scripts or commits didn't get copied, like the above, over when I initially changed some P550 naming/parameters to T550.
Some background. I had only 1 hard drive for the P550 and T550 code. I did test bluetooth and gps on my P550 and both work.
After I tested everything, I then later split the P550 onto one hard drive and the T550 to another so I wouldn't get confused when compiling and making changes. I suspect now that I forgot to copy over my T350 script to fix gps and bluetooth onto the new T550 drive.
To fix gps without having to re-download another 440MB file,
1) Boot into TWRP 3.4.0.0.
2) Click Mount. Choose System.
3) On your computer, goto
proprietary_vendor_samsung/libloc_ds_api.so at lineage-17.1 · Galaxy-MSM8916/proprietary_vendor_samsung
proprietary_vendor_samsung. Contribute to Galaxy-MSM8916/proprietary_vendor_samsung development by creating an account on GitHub.

4) Download both files above (libloc_ds_api.so and libloc_api_v02.so).
5) Goto the directory where both are saved.
6) Plug in microusb cable to tablet.
7) Then use adb to push the file using the command
Code:
$adb push libloc_api_v02.so /system/vendor/lib/libloc_api_v02.so
libloc_api_v02.so: 1 file pushed, 0 skipped. 7.6 MB/s (116316 bytes in 0.015s)
$adb push libloc_ds_api.so /system/vendor/lib/libloc_ds_api.so
libloc_ds_api.so: 1 file pushed, 0 skipped. 29.5 MB/s (26132 bytes in 0.001s)
8) Check that both files exist.
$adb shell ls -al /system/vendor/lib/libloc_api_v02.so
-rw-r--r-- 1 root root 116316 Dec 7 2020 /system/vendor/lib/libloc_api_v02.so
$adb shell ls -al /system/vendor/lib/libloc_ds_api.so
-rw-r--r-- 1 root root 26132 Dec 7 2020 /system/vendor/lib/libloc_ds_api.so
9) Reboot into system and GPS should be work now.
I'm making a new BETA image again and before I upload it, I will retest everything again on my P550. It's a bit awkard as everything is mapped backwards on the X-axis.
I'll post here when it's up.
Well it was around 1AM in the morning when I saw the gps not working post and now it's 2:13AM. I'm just waiting for the last 5 minutes of my new build, but the host server is having major problems right now.
So I'm going to sleep and will try uploading the new image tomorrow after I retest everything with the P550 running the T550 image. Everything will be mapped backwards for me on the X-axis while testing.
Dec 21 BETA build up. Androidfilehost is having major problems so I put it up on sourceforge.net. No way I could go to sleep with this hanging over my head. It's 2:30AM. Now I'm going to sleep in tomorrow.
Dec 21 build has gps fix.
Ooh i want really like to test!
