Debian Squeeze on GT540

Hi,
I start this thread to speak about natively running Debian Squeeze on LG Optimus GT540.
I have put somme script to bootstrap complete installation on sdcard on :
poivron.org/~jimpulse/swift
Please read README first.
Kernel is 2.6.29 from lge source with minors modifications :
* lge source don't compile properly ( this is not what is distribute as binnary ?GPL violation? ).
* Framebuffer console on startup.
* Software refreshing enable.
* Race condition on mddi register function when using software refresher
* Inkernel command line.
* ext3fs
Kernel debian packages are in swift/kernel
the boot image is in swift/boot and is reconstruct at end of bootstrap.
Lxde environement with matchbox-window-manager and matchbox-keyboard is working fine for me.
Slim is used as display manager in autologin mode.
Freesmartphone is installed but not configured (TODO)
Wifi (4325) is working but module is not loaded on startup. The firmware is from lge source distribution but is the same as on binary distribution.
Bluetooth (?4325?) is not working. (blueman need dpkg --configure at first startup). (TODO)
Enjoy.

i got: You don't have permission to access /~jimpulse/swift/README on this server.

You don't have permission to access /~jimpulse/swift/README on this server.
Says when i try to open README file

Sory, I"m noob !
Now, It's working.

I didnt understand how it's booting. What should i do. Just flash boot.img to recovery then boot from it? Is it enough or what should i do can you write it step by step?

Hi,
You must install debian on first partition of your sdcard.
The partition must be ext2 or ext3 formated (preferably ext3).
The script 'bootstrap.sh' is make for that, you have to be root to use it.
the card must be mounted with suid,dev,exec .
you must have installed somme packages on your host, read README file.

hi there,
so its something like a dual boot ?
something like this http://forum.xda-developers.com/showthread.php?t=1408824.

Hi,
It is not dualboot by itself.
It is just a scritp to install Debian Squeeze armel on sdcard and build a boot image.
More explanation :
!!! Please, dont run the script if your dont understand what it do !!!
You have to edit the script to match your preference :
ROOT=<the target directory where to install to>
ROOTDEV=<Name of the device were your phone will look to find root filesystem>
This script is tested only on Ubuntu oneiric but should work on other debian-like distros.
You can format your sdcard like this : sudo mkfs.ext3 -L swift /dev/XXX
where XXX is the device file corresponding to the partition you want to format. You can figure out that by looking at kernel message after inserting the sdcard : dmesg
Eject and reinsert the card to mount the new filesystem.
Remount the filesystem with apropriate options : sudo mount -o remount,exec,suid,dev /media/swift (or wherether your filesystem is mounted).
So, change ROOT= variable as ROOT=/media/swift (or whatether ...)
and ROOTDEV=/dev/mmcblk0p1 (for the first partition of the sdcard)
Then run in the swift/ directory : sudo ./bootstrap.sh
If all is right, it take aprox 4 hours on my [email protected] to download and install everything.
After installation, you have choice to flash the boot rom (eg : sudo fastboot flash recovery /media/swift/boot/boot.img-2.6.29-swift) or to use it as chroot environnement from android.

I have done it for one time but it didn't boot So im gonna do it again tomorrow. I dont have time today

I'm always having problem with the script. Now im starting again. I hope it will done this time... And can you use a .35 kernel for this?

Hi,
I'm planning to include .35 kernel, but I dont know which one to use. I've start a thread to ask people there preferences. Kernel need minor modification to have frame buffer console working.
If you have probleme with the script, post last few line of output and I will try to help.

I have the mismatch size problem with the one of xorg-bla-bla packages By the way Mikegapinski's kernel is good to work i think.
Edit:
And does this make a problem?
pre-installing dpkg
warning, in file '/var/lib/dpkg/status' near line 3 package 'dpkg':
missing description
warning, in file '/var/lib/dpkg/status' near line 3 package 'dpkg':
missing maintainer
Click to expand...
Click to collapse

These two warning are not a problem, these are only because dpkg/status is not complete before installing dpkg. It's a bootstrap edge effect (dpkg need dpkg to be installed).
If the script don't run until the end, you should have a phase number given at end of output. You can skip already ran phase by passing a phase number as parameter to the script.
The xserver-xorg-core problem is about dependencies against all video driver. So I mangle the control file to remove these dependencies. Perhaps this can fail if debian repo version has changed.

Now i have bootedup but how can iload the wifi module now?

Hi,
The default password for root is root .
There is no sudo preinstalled so use su.
Firmware and nvram settings are in /etc/wl as for android names rte.bin and nvram.txt .
You have to pass parameters at load time :
modprobe wireless firmware_path=/etc/wl/rtecdc.bin nvram_path=/etc/wl/nvram.txt
or put this in /etc/modprobe.d/wireless.conf :
alias wlan0 wireless
options wireless firmware_path=/etc/wl/rtecdc.bin nvram_path=/etc/wl/nvram.txt
Wicd is not working correctly so you have to configure by hand
(iwconfig and ifconfig) or edit /etc/network/interfaces. (view debian administration guide for that).
I will update the script tomorrow to add a configuration file for modprobe and an alias to wlan0.

Thanks for these and how can i access the command line from my computer?

Hi,
Sorry, but I've forget to put openssh on package list. I'he also froget to add debian repo to sources.list .
Edit /etc/apt/sources.list with nano or vi and add a line with :
deb http://ftp.debian.org/debian/ squeeze main
then run apt-get update
You have to use the lxde terminal to configure wireless and install openssh-server (apt-get install openssh-server).
After that, you will be able to connect with ssh (ssh [email protected]<IP ADDRESS>) from your computer.
adbd is not working and need some tweak to work with debian.

Jim

Hi,
I've update bootstrap.sh :
* openssh-server and openssh-client are installed per default
* sources.list is now created durring bootstrap with same repo that the bootstrap process used.
* modprobe is configured to pass correct parameters to wireless module. There is also ans alias wlan0 ponting to wireless.
* network/interfaces is update to have the loopback interface configured at boottime. The configuration for wlan0 must be tweak for your network (essid, dhcp or static ...) .
Now, I'm working on 2.6.35 from wingrime and hope to publish it next week.

Yeah i wonder it too. I is so good to have debian on my phone. It'll be more usable with a touchscreen gui. It doesn't lag more. I think you should change the keyboard to a bigger. And we should can rotate screen. At least with running a sh file from terminal By the way you're great! I think this is gonna be awesome for our phones...

[GUIDE] Compile CWM Recovery

Hi. I am creating this guide because i did not find any particular functional guide with details.
You must be running a 64 or 32 bit version of Ubuntu. Please note that i wont be going in the details on how to setup a build environment and sync sources as there are many guides for that.
Step 1 :
Install the required packages
Step 2 :
Setup the build environment and sync the sources for the required CWM. CWM source comes bundled with the CyanogenMod source.
Code:
CWM 5 - Gingerbread
CWM 6 - Jellybean
Step 3 :
Now we come to the actuall compiling part. Make sure you have synced the latest source using the "repo sync" command.
Change directory to your source.
Issue this command :
Code:
make -j4 otatools
Step 3.5 :
Do this step if your device is not officially supported by CM10.
Using terminal emulator on your device, issue the command
Code:
dump_image boot /sdcard/boot.img
This will dump the boot image to your sdcard. Transfer it to your home directory.
To build Android from source for a new device, you need to set up a board config and its makefiles. This is generally a long and tedious process. Luckily, if you are only building recovery, it is a lot easier. From the root of your Android source directory (assuming you've run envsetup.sh), run the following (substituting names appropriately):
Code:
build/tools/device/mkvendor.sh device_manufacturer_name device_name /your/path/to/the/boot.img
For example if you are having the Samsung Galaxy Ace device, the command will go as follows :
Code:
build/tools/device/mkvendor.sh Samsung cooper ~/boot.img
Please note that Cooper is the device name. Only use "~/boot.img" if you have the boot image in your home directory. Or else please specify the correct path.
You will receive the confirmation "Done!" if everything worked. The mkvendor.sh script will also have created the following directory in your Android source tree:
manufacturer_name/device_name
Step 3.5 ends here.
Step 4 :
Now that you have the device config ready, proceed.
Type the following code in your terminal in the source directory.
Code:
. build/envsetup.sh
This will setup the build environment for you to work.
Now launch the command
Code:
lunch full_device_name-eng
This will set the build system up to build for your new device. Open up the directory in a file explorer or IDE. You should have the following files: AndroidBoard.mk, AndroidProducts.mk, BoardConfig.mk, device_.mk, kernel, system.prop, recovery.fstab, and vendorsetup.sh.
The two files you are interested in are recovery.fstab and kernel. The kernel in that directory is the stock one that was extracted from the boot.img that was provided earlier. For the most part, recovery.fstab will work on most devices that have mtd, emmc, or otherwise named partitions. But if not, recovery.fstab will need to be tweaked to support mounts and their mount points. For example, if your /sdcard mount is /dev/block/mmcblk1p1, you would need the following lines in your BoardConfig.mk
/sdcard vfat /dev/block/mmcblk1p1
Once the recovery.fstab has been properly setup, you can proceed to the next step.
Step 5 :
Now we build the actual recovery.
Code:
make -j4 recoveryimage
This command builds the recovery image
You can use the command
Code:
make -j4 recoveryzip
to make a fakeflash recovery i.e. a temporary recovery to test out on the actual device.
Your recovery can then be found at "your_source_directory/OUT/target/product/device/recovery.img" and the temporary fakeflash zip in the utilities folder at the same location.
If everything works out well, you will have a working recovery.
Once you have working builds, notify "koush", on Github and he can build official releases and add ROM Manager support!
------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Some tips :
If you want to compile CWM 6, sync the jellybean branch using the command :
Code:
repo init -u git://github.com/CyanogenMod/android.git -b jellybean
repo sync
If you want to compile CWM 6 on a 32 bit system, you need to sync THIS source too. Instructions are given in the readme.
Run "make clobber" between builds if you change the BoardConfig.mk, or the change will not get picked up.

Koush for this guide.

Nice.
Will come in handy

Excellent guide!
Thanks!

I will try on my Motorola PRO+, wish me luck

any ideeas how i can make the recovery font smaller? i read somewhere that i have to edit ui.c file, but what syntax? thanks

thank you for this
i will try to compile this
i tried before using koush online builder but the cwm has bugs.

Okay, I'm problly stupid, but.
repo init -u git://github.com/CyanogenMod/android.git -b jellybean
seems to work fine, but
repo sync does this:
Code:
fatal: '../CyanogenMod/android_abi_cpp.git' does not appear to be a git repository
fatal: The remote end hung up unexpectedly
error: Cannot fetch CyanogenMod/android_abi_cpp
What did I screw up, or not have prepared correctly?
I have built AOSP and currently build kernels on this box, so I know git and all that is setup correctly.

Hey guys, i present to you a new updated version of CyanogenMod Recovery a.k.a CWM 6.0.1.3. The current version that we use is 5.0.2.6
Edit : As you guys know, i bricked my ace while trying to get CWM working. The bootloader is lost. So there is no way i can get it working back. This is the end of developing for me for now atleast. I will have to replace the motherboard or get a new device. Any dev wanting to take over the project, please feel free. Contact me for help and i will try my best. But if you use my sources, please give credits to me and TeamCooper.
My sources are here.
Edit : You can refer my guide on compiling a recovery here.

now afraid to do it on my own

So you copy pasted a guide (and linked it in the end), and then you say you can't find any other guide.
Orelly?

Can jou tell a bit more about run "envsetup.sh"thats what i mis in this guide and the original guide. and most other guides.
The file "dump_image" needs to be placed on the phone. Can be put on the sd of the phone and than place on a place you like.(Folder bin/xbin ore some other) Use terminal on the phone. (any from google store play) cd to the dir the dump_image is than run the command.
How do i find the device name for my phone/tablet. I know the name of the tablet i bought.. But still. samsung ace hase device name cooper? Where did you find it?
Thx by the way. This guide is a bit more clear than the original.

the device name is in build.prop

dump_image would be on the phone, it was for MTD devices now a days ytou want to use DD on mmcblk devices

i solved the font problem, you need to edit the Anndroid.mk from bootable/recovery, but now i got messed up Graphics in the recovery and i cannot boot back into the OS. ideeas? thanks
PS: i think that the graphics.c may be the problem. but for booting, i really have no clue.

This will give you a non touch version of CWM
Any idea if the touch modifications are also available opensource to modify code?

Not yet. But finding it. Once I get it working, will add it to the op.

Thx for the answar on my question.:good:
I have a nother question:silly: For example, my recovery.fstab hase: /sdcard mount is /dev/block/mmcblk1p1

Porting to a new "unknown" device
Hi folks. I`m trying to start to develop some stuff to an chinese tablet and, of course, my first need is the cmw ...
Then. I only can have it using the fakeflash method(locked bootloader). My problem that it`s kinda new stuff to me.
I have some files built by utkanos to start the job. But now I dont know where to go to ...
Theere appears do be no documentation in what files in what folders I have to edit/add to get it fully functional.
When i flash the zip and the cwm load there`s no partition table. It loads a lot of errors on the screen saying no /dev/block* ...
I little help will be much appreciated here. Even just a start point .. anything that can help!

wifi turning itself off, driver not being loaded.

Edit: Considering all the complex processes that I've done, I'm willing to do some series of steps again with the gathered knowledge, but I still need some guidance.
Actual status: Losing my mind (not fixed)
Here's the info of my current problem:
I have a XT1563, cid12 (cl)
Working perfectly until android 6.0 OTA. After restart, in the wifi screen loading bar is constantly present and switches itself off after a couple of seconds of activated. Network list is empty, mac address appears as 02:00:00:00:00:00 in wifi details and status of the phone.
Sent it to support and they 'updated the software', when I got it back wifi was working, but when I installed sd and sim cards back it stopped working.
The most relevant logcat message that appears to be the main one is from WifiStateMachine:
Code:
WifiStateMachine: Fail to set up pno, want false now false
WifiStateMachine: Failed to load driver
Things I've done
Most of this steps have been tried with clean installs and removing sd/sim cards
Network Reset
Factory Reset
Flash different stock roms (currently on 6.0.1 MPD24.107-52)
Flashed ultra kernel R2, R3 and squid kernels 14, 15, 15 oc, 15b
Used twrp 2.8.7 and 3.0.0-r2
Used rsd to flash official firmware for my carrier (RETLA-ENTEL_6.0_MPD24.65-25.1)
Flashed CM 12 and CM 13 unofficial
Installed SuperSU and Busybox
Changed owners and permits in persist/
Copied new persist from different sources
Hex edited .bin file in persist/
downloaded WCNSS_wlan_dictionary.dat and put it in persist to comply with symlink in prima/
fastboot oem install [2 of my carriers; entel, claro]
Replaced WCNSS files in persist with the ones available the motorola repo
Copied WCNSS factory file to prima/ folder
Copied WCNSS_qcom_cfg.ini to /data/misc/wifi
went crazy with 776 permissions
Even after flashing stock with RSDLite, bootloader show the modified status as 3 when I think it should be 2. This has led me to think that something is in the file system that android does not like but is not being fixed by RSD nor clean wipes.
From what I understand, the only thing that could be surviving full flashes and wipes are contents in persist/ and modifications to the root of the system, like busybox and superSU. I've not been able to find any way of cleaning the root of the phone and I imagine that's really dangerous.
TL;DR Wifi driver is not loading, persist folder is ok and clean flash does not fix it.
Possibly relevant logcat entries:
E WifiService: Invoking mWifiStateMachine.setWifiEnable
D WifiStateMachine: setting operational mode to 1
E WifiHW : User build,dont Start logging service.
E WifiService: Invoking mWifiStateMachine.setWifiEnabled
E WifiStateMachine: Failed to load driver
D WifiStateMachine: setWifiState: unknown state
Info for nerds:
Source code of WifiStateMachine.java containing the error message:
Code:
public boolean processMessage(Message message) {
switch (message.what) {
case CMD_START_SUPPLICANT:
[B]if (mWifiNative.loadDriver())[/B] {
// Code for loading supplicant
} else {
loge("Failed to load driver");
}
break;
# More code
}
}
WifiNative.java cointains the class being instantiated where the evaluation calls a empty abstract method:
Code:
public native static boolean loadDriver();
I'm having problems for identifying where this class is being extended for this method to actually do something. If anyone knows please leave a comment.

Wifi problems and fixes
I've still not found a solution for myself, but I figured I still can give some tips for people with problems, especially considering how confusing is to get information about this.
This is a work in progress. I would gladly receive corrections and new info.
Before anything, do a backup. Even if your wifi does not work, it can save you from a lot of problems. Remember to backup the persist folder, a lot of automated recoveries don't make a backup of that folders because it's supposed to survive flashes but there's ways in which you can do it by mistake. It also helps a lot with bug hunting.
Things you should have already tried:
Plane mode on, reboot, wifi on and plane mode off
Network settings reset in android and reboot
Rebooted to safemode (longpress in power off when turning phone off]
Factory reset in android
Removal of SD and SIM cards
Factory reset in recovery
Flash Stock ROM in RDSlite
Unlock bootloader
Activate developer mode and set usb debug on
Installed custom recovery
Clean Flash stock ROM trough fastboot
Flash custom Kernels
Things you need:
adb and fastboot
usb drivers for the phone
Optional Text editor that preserves text format (avoid notepad and MS word)
Optional Busybox for extended commands in android shell (root required)
Optional If you're in windows and want to mess with adb: A decent console to work with.
Option A: cash with cmder
Install cmder
Install NodeJs
Install cash tipping in cmd npm install cash-global -g (after NodeJs)
Option B: babun
http://babun.github.io/
optional Open text editor for easy copy-paste of long paths and commands
optional Hex editor if you want to edit .bin files. I use XVI32
Useful console commands (In windows you need one of the optional shells described above)
List files and folders
Code:
ls -la [path to list]
Find file/folder in linux (and android shell)
Code:
find / -iname '*[word you're looking]*'
* are 'wildcards', they allow for matching any text (or no text at all)
you can add, before -iname, -type f (for files) or -type d (for folders)
Symlink
It's an alternative of copying files. this allows you to simulate having a file in two different places, but really all paint to one. Modifications in this source are going to affect all the links, so it's easier to configure. Android does this a lot.
Code:
ln -s [path to] [from]
Copy files and folders
Code:
cp [-R if you want to move folders] [path to source] [path to target]
logcat for essential wifi messages (short-colored) If someone know more, please let me know
Code:
adb logcat -v brief -v color WifiSerice:V WifiHW:V WifiStateMachine:V FileUtils:V QSEECOMAPI:V *:S
change owners and permissions
the flag -R makes the command work for files and subfolders
Code:
chown user:group [path to file or folder]
chmod [num of user][num of group][num of all] [path to file or folder] [SIZE="2"](e.g. chmod 660 /persist/WCNSS_qcom_wlan_nv.bin)[/SIZE]
grep
This one is awesome; It's for filtering the results of any command, so you can use it for filtering.
Code:
[command you want to filter] | grep -i [term you're looking for]
For example, [adb logcat] gives you a huge list of messages, but [adb logcat | grep -i wifi] gives you just the lines that contain 'wifi'
From my experience, this are the common folders related to wifi configs:
Code:
/persist/
/system/etc/firmware/wlan/prima/
/system/etc/wifi/
/data/misc/wifi/
Command list for do a full clean flash:
please note that system.img_sparsechunk can vary in number according to ROM, but I've put 9 in here because failed commands don't write to phone
note: fastboot flash partition gpt.bin works perfectly when used first, but for me it's failing when I erase system and boot first.
Code:
fastboot erase system -w
fastboot erase boot

Important: Every time you flash, do a clean wipe. In fastboot this usually means using erase system -w and erase boot before flashing.
Be aware that for getting the logcat your phone must be booted to android OS.
Be aware that for copying and modifying important files you must access the phone's shell either in recovery mode or switching to root with the command (su) that's only accesible if you're rooted.
Ok. If you made it this far you're probably losing your mind. To debug this, especially if you're going to post asking for help, get the catlog of your phone and/or a precise description to look for clues to your problem (I have a command ready for you above).
Here's some common solutions I've found while trying to solve my own problem: (Credits to the authors of the solutions)
Bad permissions/users
These appear to be correct or usable permissions for relevant files. Consider that there's a lot of fragmentation in this info so they might be wrong.
Confirmation of these would be great:
Code:
-rwxrwx--- wifi wifi /system/etc/wifi
-rw-rw---- wifi wifi /system/etc/wifi/wpa_supplicant.conf
-rwxrwx--- wifi wifi /data/misc/wifi
-rwxrwx--- wifi wifi /data/misc/wifi/sockets
-rw-rw---- wifi wifi /data/misc/wifi/wpa_supplicant.conf
-rw-rw---- system:wifi /data/misc/wifi/WCNSS_qcom_cfg.ini
-rw-rw---- wifi wifi WCNSS_qcom_wlan_nv.bin
-rw-rw---- root root WCNSS_wlan_dictionary.dat
-rwxrwx--- is 770, -rw-rw---- is 660
Is reported in some places that the parent folder of wpa_supplicant.conf should be -rw-rw---- wifi wifi
Missing or badly configured wpa_supplicant.conf
The solution is place a new copy of the file in the correct folders. If someone has a 'oficial' source or more info let me know
I remember reading that some people had success deleting the file so the SO rebuilds it. Do it to your discretion and remember to backup
Missing WCNSS files
These files are essential and must be in the correct paths for wifi drivers to load.
There's a lot of different sources for this files, but from my experiencie they don't change a lot (last commits are more than one year old).

In there you can find backups to get the folders, restore them to /persist/ and check permissions.
Bad MAC address in WCNSS_qcom_wlan_nv.bin
Sometimes the file WCNSS_qcom_wlan_nv.bin needs to be updated with the correct mac address.
Since it's a .bin file, it cannot be changed with a text editor. You need to use a hex editor (XVI32 link is in 'things you need' above).
The mac address starts at 'A' (since is hex) or, more simply, after 10 'cells'. Be aware that in this editor changes get 'inserted' instead of modified, so you have to delete the initial 6 addresses of the old mac.
Put the file back, and check permissions. There's two copies of this file: one in /persist/ and another in /system/etc/firmware/wlan/prima/ change one or both according with your situation
Some logcat messages and details about them
For getting more messages about wifiHW you need a userdebug build like CyanogenMod. Stock roms don't log wifiHW.
Code:
WifiStateMachine: failed to load driver
WCNSS_qcom_cfg.ini and/or WCNSS_cfg.dat is missing somewhere. In my case this was missing from /system/etc/wifi.
Code:
wcnss_service: CAL file not found
This refers to the calibration file. The source of wcnss-service.c defines this file as "WCNSS_qcom_wlan_cal.bin" in the path "/data/misc/wifi/WCNSS_qcom_wlan_cal.bin". however, source show that CAL file is not used if the factory file is present. Source in link gives this address '"/data/misc/wifi/WCN_FACTORY" which is weird because from posts in xda this file has the name "CNSS_qcom_wlan_factory_nv.bin" I'll update if I have more info

Thank you for your answer!
I'll make the edit in the file but I'll take a while to report back on the results because it's already too late in here.
Considering this, would it make sense for a nonmatching mac address show up as 02:00:00:00:00 in the wifi details screen?

Yes, your Mac address is fine, just checked I also have the same
try this and report if its working
1. Put the phone into airplane mode.
2. Restart the phone.
3. Turn on WiFi.
4. Connect to the WiFi network.
5. Turn off airplane mode.

I have tried the modifications to no avail.
Steps I did:
get the wifi mac address from the recovery logs
adb pull the files on recovery with persist mounted
hex edited the lines taken from the screenshot on your second link (Both _factory_nv.bin and _nv.bin
adb pushed lines back to mounted persist on recovery
cleaned data/cache/dalvik
rebooted to system
Is there something in the /data/ folder that could be causing the issue? Now both files show back at -rw-r--r-- permissions with root:root owner. I'll try again without wiping data this time and post the report.

I have tried the steps in that topic, copying the exact same files in /persist and /prima. Problem still persists
From that topic I've learned that at flash time the files from persist are taken out and sent to system folders. I will try to reflash now with the new files and permissions set up

After the actions of my last post and before the new flash, I scanned the results of adb logcat *: D | grep Wifi
Here are some entries that could be of interest:

I've fully flashed the device with RSD and problem still persist.
Eager to hear some more ideas.

I noticed that in system/etc/firmware/prima, adding to the files I copied, there's one symlink: WCNSS_wlan_dictionary.dat -> /persist/WCNSS_wlan_dictionary.dat
This file is not present in my persist folder (nor the rest of the files in the phone, based on adb shell find . -name WCNSS_wlan_dictionary.dat). I imagine this could clearly cause a problem with the wifi driver looking for a file that does not exist.
Someone has a reliable source where I could get this file? I can try to delete it to see if the SO tries to rebuild something, but I would prefer the safest option first.

have you tried flashing back stock recovery then do a factory reset from there?

copy WCNSS_qcom_wlan_factory_nv.bin to your SD card. Use your filemanger to copy this file to /prima. Reboot
Activate wi-fi, the you'll find your mac adress under Settings > About Phone > Status > Wi-fi MAC Adress
Open WCNSS_qcom_wlan_factory_nv.bin on your phone or PC with a hex editor and type your mac adress inside that file and save it.
File attached just remove .txt
The file is from xt1562

Thank you for the file and the instructions. I've checked the diff with 3 different sources:
Meninblack007 - vendor
huawei_msm8916
google android source code
All match, so I'll asume this is a universal file without modifications.
Moving this file to persist/ folder made no difference
I've also tried taking the files from motorola official github repo, copy them to persist/ and flash. Without success this far.
I'll send factory_nv.bin to prima folder and report back

flash the firmware through rsd lite, lock the bootloader and take it again to service center.
I am out of ideas and also Google searches.. I'll keep looking and report if I find anything else.

Considering all the changes I've done, it was a good idea to try again.
I've tried the last release of squid kernel, since the dev of ultra kernel recommended this one for 6.0.1.
Installed the kernel, wiped cache/dalvik and rebooted without success. Logcat is still showing failure at loading drivers.
The main problem I'm having is that the failure point is not correctly specified, so now I'll try to dig deeper into logcats to see if I pinpoint the source of the issue. If anyone can let me know about some complementary logs, I would be super grateful.

I've installed CM to have a userdebug build, in order to debug more in detail thanks to the logs of wifiHW.
After fixing an error of missing WCNSS_qcom_cfg.ini in /system/etc/wifi (Copied from prima folder) I've came across this error appearing persistently:
Code:
wcnss_service: Failed to open /dev/wcnss_ctrl : Bad address
I've looked around but there's no info of how could I deal with this. I will dig around a little more but if someone has a tip I would gladly hear

[GUIDE]How to extract /system from Samsung S7 OTA/FW in Windows without a Phone

This is a complete working guide on how to extract the /system partition from a Samsung S7 FW/OTA package using Windows (This is the same package one might flash to their phone with ODIN.) You can get this FW/OTA package from sites like Samsung-Firmware.org & SamMobile.com. It is very likely this works (or parts of it duct-taped together ) on other Phone models,etc, but I vouch that this guide works on the Samsung S7. Please chime in if it works on other models & brands!
Intro:
I found a LOT of guides similar to this, but couldn't get any to work with the Samsung S7 packages! And there are MANY different versions of the tools I mention below, many not working! So be sure to use the tool versions I post below. Over much time, it was a tiny step with each new attempt until I finally got it...& wanted to share!
Purpose:
Why would anyone want to do this? If you're reading this thread and don't know the answer to that, then I'm confused But I'll answer anyway - What is the purpose of this thread?
You would want to do this because you're a ROM Developer and don't want to have to go through the time & trouble of installing an OTA, then do a dd/cat to get the system image, etc. (With this method you don't even need a phone, just a PC!)
You are using a custom ROM, but want a stock app; for example the custom ROM you're using has the Google Dialer/Phone app builtin, but you prefer the stock Samsung Phone. Doing the steps outlined here will yield a "system" folder in Windows that you can simply navigate to /system/app or /system/priv-app and copy over the apk to your phone and install it! (via ADB or phone File manager app, etc). Obviously not all apks will work. Or maybe you want the libraries from another phone OTA package in order for an apk to work, and so on...
You are just curious what's in the /system partition for an OTA package!
Tools:
7-Zip
LZ4
simg2img: "Clone or download"->Download ZIP
Ext2Explore (Same as Ext2Read)
Guide:
Download FW/OTA (TMB-G930TUVU4CRI2.zip) from SamMobile website (or whereever)
Use 7zip to extract TMB-G930TUVU4CRI2.zip to a folder
Use 7zip to extract AP_G930TUVU4CRI2*.tar.md5 to a folder (ignore "There is no correct record at end of archive" error)
Use lz4 to extract system.img.ext4.lz4 -> system.img.ext4
lz4 system.img.ext4.lz4​
Extract simg2img_win-master.zip -> \simg2img_win-master\
Copy system.img.ext4 to \simg2img_win-master\ folder
Rename system.img.ext4 -> system.img
Use simg2img_win-master to convert system.img -> system.ext4.img
Double-click convert.bat (or run in cmd prmpt) (This will take a few minutes)​
Create new folder to save contents in, eg: "C:\System"
Use ext2explore to mount system.ext4.img: Open ext2explore->File->Open Image->Select system.ext4.img
Click Save icon->Save to your new folder, eg: "C:\System"
Wait for it to extract. Once complete, enjoy!

Just happened to see this thread.
Dropping in the let you know for linux just do this
Code:
simg2img system.img.ext4 system.img
mkdir system
sudo mount -t ext4 system.img system/
Of course all work is done in the current working directory.
You can just copy whatever you want from this mounted loop device of the system.img or whatever.
This is what i do because it seems to be the fastest in terms of work.
Hope it helps. I prefer all android work on linux

HU - Allwinner T8 Core - Asottu - How to resign the partition updated in a firmware

Hello,
Because of sound issue (volume of radio stays always over waze despite any settings) and ADB issue (impossible to authorize my HU though wifi, can't copy the laptop public key into the HU adb directory), I've decided to customize the firmware of my HU.
To do this, I catched an official firmware from my provider (V9.4.1_20190829.100539_AKW1-FD).
Content of the zip archive is:
- c23c0812-a146-11e9-948a-6f966dc3faf9 (0, 1, 2)
- c1434ea2-a146-11e9-8113-67e2f4bd95ae
- c5759110-a146-11e9-a26c-c7232518a533
A check on the different files gives me,
file c1434ea2-a146-11e9-8113-67e2f4bd95ae ==> that's data
file c23c0812-a146-11e9-948a-6f966dc3faf9 ==> that's a filesystem using ext2 (so I can mount it, but it's splited in 3 parts)
file c5759110-a146-11e9-a26c-c7232518a533 ==> that's a filesystem using ext2 (and the boot partition)
- First propblem (sound volume issue):
Now to make my changes I need to mount the partition:
sudo mount -t auto -o loop c5759110-a146-11e9-a26c-c7232518a533 img/
Then I changed in the file /etc/audio_policy_volumes_drc.xml (in the endpoint used to mount the partition) and save the following:
<volume stream="AUDIO_STREAM_NOTIFICATION" deviceCategory="DEVICE_CATEGORY_SPEAKER">
<point>0,-2400</point>
<point>33,-1600</point>
<point>66,-800</point>
<point>100,0</point>
</volume>
like that, the attenuation in Millibels of Notification (used by Waze) is not so hard as AUDIO_STREAM_MUSIC is defined
Now, release this partition (sudo umount img/)
- Second problem (adb key directory not writtable)
Because the file c23c0812-a146-11e9-948a-6f966dc3faf9 is the partition splited into 3 parts, I need to rebuild the whole partition:
cat c23c0812-a146-11e9-948a-6f966dc3faf9* >c23c0812-a146-11e9-948a-6f966dc3faf9
Now I have the partition able to be mounted
sudo mount -t auto -o loop c23c0812-a146-11e9-948a-6f966dc3faf9 img/
Then I updated the init script init.usb.rc (in the endpoint used to mount the partition) and save the following:
mkdir /data/misc/adb 777 system shell
Then I will be able to copy a adb_key into this directory (using a terminal on my HU) and link with my laptop
Now, release this partition (sudo umount img/) and split it again:
split -b 400m c23c0812-a146-11e9-948a-6f966dc3faf9
You will have several files (xaa,xab,xac), you have to rename:
xaa --> c23c0812-a146-11e9-948a-6f966dc3faf9.0
xab --> c23c0812-a146-11e9-948a-6f966dc3faf9.1
xac --> c23c0812-a146-11e9-948a-6f966dc3faf9.2
Looks like a charm but I'm facing against the signature of the files updated (if I use directly theses files my HU does not care about them)
Does someone know how the sign the files again ?
Thank you for your help

no one has changed content of the firmware and sign it again ? please

Nobody knows how to repack the ext2 partitions to android ?
My HU do take care of the partition upgraded, so I assume it has detected something despite the partitions are still readable... Checksum ? Signature ?
