[Q] how to flash from AOSP builded images?

Hello!
Im currently trying to build a vannila froyo 2.2 rom from the source! How do i flash the images when im ready? Is there something like fastboot on the g1 or htc magic?

I haven't had the time to try to build myself, but wouldn't you be better off starting with the Samsung open source for your carrier/model rather than trying to figure out all the changes you'd need to make to get AOSP to run on the Tab?

Erhh - Samsung open source only contains the kernel. You need the rest of Android, which is what the AOSP is for!

Dave

Don't know about the others, but the one for the SCH-I800 on VZW is not just the kernel. All of the things like the custom notification bar/settings for white and black levels, et cetera, go well beyond vanilla android in the Tab. I haven't gone through the platform.tar, but it has notices about stuff for, TouchWiz, et cetera (now whether it can actually run as built directly from what they've made available all bets are off, I know a direct compile of the kernel code didn't work for me, but I haven't had time to do more than a simple straight attempt to build and may have screwed something simple up). It's around 85MB for the DJ11 code for Verizon.
Edit: I'd understand if you needed most of it from AOSP though for a full build, and stand corrected.

And how do i flash the created system.img and data.img? The kernel will be in the zImage format as im going to build the kernel from samsung's opensource files!

You don't. Samsung uses different partition layout and formats.
Use the Samsung tar files to overlay over AOSP as described in their readme file.

Ah ok! Thank you

from Readme file:
How to build:
< Kernel >
1. Unzip SPH-P100_Kernel.tar.
( You can find SPH-P100_Kernel.tar in the same directory with this README.txt . )
2. Refer another "README.txt" in the tar file to build the kernel source code.
< Platform >
* NOTICE *
Galaxy Tab is launched in many countries, including Europe and North Amarica.
S/W is almost the same but there are some differences between the European version(GT-P1000) and the US Sprint version(SPH-P100).
The open source codes to be open here are only the differences.
1. Get Android open source code:
: version info - Android froyo 2.2 (android-cts-2.2_r2)
( Download site : http://source.android.com )
2. Get GT-P1000 open source code
: GT-P1000_OpenSource.zip
( Download site : http://opensource.samsung.com )
Unzip it, then you will see the file GT-P1000_Platform.tar.bz2 which includes the platform source code.
3. Overwrite GT-P1000 Platform OpenSource to the Android open source.
4. Get SPH-P100 open source code:
: SPH-P100_OpenSource.zip
( Download site : http://opensource.samsung.com , version info : DJ14 )
5. Overwrite SPH-P100_Platform_DJ14 OpenSource to the Android + GT-P1000(European) Platform open source code.
6. Overwrite the Platform source code that comes from the Sprint version(SPH-P100_Platform_DJ30).
7. Do "make"

If I understand correct. (for the kernel at least) You could just take a package like monks then swap out the zImage and *.ko files for the samsung ones. resign the zip. Then flash it from the clockworkmod recovery.

I believe we need repo init -b android-cts-2.2_r2 ... and overlay the Samsung tar contents on top of it.

[Q] help build cp210x.ko on Iconia A500 3.2.1

Hi,
I really need the cp210x.ko module, but I couldn't successfully build it properly for my Iconia A500 with 3.2.1 and 2.6.36.3+ kernel.. I get the following when I tried insmod my cp210x.ko build using ubuntu cross compiler approach:
cp210x: version magic '2.6.36.3+ preempt mod_unload ARMv5 ' should be '2.6.36.3+ SMP preempt mod_unload ARMv7 '
A little search showed that I need to build it in ARMv7, and need to set the kernel config to build SMP kernel. In this thread I saw a few modules offered but couldn't post reply as a new xda-developers user, so I post here. My A500 has already been rooted via the su (version 3) method posted few days ago.
Please help me build the cp201x.ko module - I am kinda stuck..
Bill

Bill,
Might I suggest you look at loading one of the many custom ROM's that will have what you want? If you are rooted, then install CWM (ACER Recovery from the marketplace) which should allow you to load custom ROM's. In order to load the cp201x.ko module you'd have to recompile the kernel and people doing this type of work normally are building custom ROM's.
Anyway, just my 2¢

Thanks for the advice. I am testing Thor ROM at the moment. Cool..
From what I can read and see within various ROMs /system/lib/modules, very few (out of total possible) kernel modules made it to these custom ROMs - mostly to get game controller to work, extra filesystems, or networking protocols. USB-to-serial modules are rare and certainly my search didn't turn up cp210x.
Cross-compiling the kernel source on Gentoo is mentioned to be better supported then ubuntu, due to its crossdev toolkit, as I'm trying to figure out how to specify target ARMv7 instead of ARMv5 I'm defaulting to when cross compiling from Ubuntu's arm-linux-gnueabi-*
I'm wondering if various nice ROM cooks have releases of their modified kernel source - or might be willing to help me build the just the cp210x as a .ko module, e.g. in the .config, "CONFIG_USB_SERIAL_CP210X=m" - I've found a post few months ago where a successful build and insertion of cp210x module was done but he had some problems when initiating communication on it - I fear the worst but hope for the best, and would like to try that myself as I've successfully talked to my device through the cp210x module on Linux.
Or, if any tips on how to build kernel (just the modules really) properly e.g. As Thor's ROM version number hints at need for some custom and virtualized build environment, I'm looking for the quick and dirty solution if cooking ROMs/kernel/ko's has steep learning curve..
Any help much appreciated!
Bill

It looks like I was speeding down the the wrong track last few days
Apparently the /proc/config.z copied off the a500 device was missing something - and how strange that is - so I had to enable SMP and choose Tegra 2 ARM processor using "make menuconfig" to get the vermagic on the build module (e.g. modinfo after successful make modules) to show ARMv7 and SMP, build from my Ubuntu cross-compiling setup. I haven't tested this new cp210x.ko on a500 yet (as it's currently running one of the customized ROMs that has different EXTRAVERSION/vermagic to the stock Acer kernel source version 2.6.36.3 that I'm based on.
I think it'd be really wonderful if various Android kernel and kernel module makers release their kernel config, sync'ed to each ROM or kernel release, so people like me may independently build special purpose kernel modules with more efficiency and accuracy (to target their customized kernel), and we can recontribute back to to a growing list of tested and working modules for corresponding devices.
Bill

Hmm... Silly. It looks like Thor's ROM already has cp210x build-in, not as a loadable module but compiled in. My device is reported to attach to ttyUSB0! How nice
Thanks!
Bill

For those who are interested, the cp210x.ko module build using latest mentioned approach, e.g. modified kernel config.z, generate module that appear to insert correctly into lightspeed and taboonay roms (neither has this USB-to-serial module) - with a little modification of the EXTRAVERSION variable in the Makefile.
Bill

CP210x and GT-P7500
Has anyone got CP210x module working with Samsung Tab GT-P7500? My problem is that the connected USB-device doesn't create node dev/ttyUSB*. I have spent lot of time trying to figure this one out.
I have tried 1) Manually compiling the linux kernel that has cp210x support as a module. After compiling the module I tried insmoding the cp210x.ko to a running kernel, but even though it seemed to load and unload all right, it did not give me the wanted results. It does not create device node /dev/ttyUSB*. I have also tried modifying ueventd.rc for adding this row, but I am guessing it is only relevant for permissions after the node is created.
Also 2) loading cyanogenmod 10 (which should have cp210x support) to tablet but it doesnot create the desired /dev/ttyUSB* node. I can see device file under dev/bus/usb/001/ but the node does not exist.
I am going to try making needed files for building custom kernel and inserting to tablet. However, I have 0 experience on this, I think it can be tough one.
Any help would be welcome, thanks.

[GUIDE] How to build AOSP kernel from source S4 Mini (i9195 & i9190)

Welcome to Kernel build guide.
WITH THIS METHOD YOU WILL GET installable zip for your kernel.
My english is not best but i think you all will understand this guide . I write this guide because i dont own S4 Mini anymore and unfortunally i cant build kernels or roms anymore for s4 mini.
this is my kernel build method. you will have everything (tools) for build a kernel for s4 mini device. if you have questions, then ask it here. this kernel method is working only aosp based kernel (not tested for tw kernel but it may also work but you need ramdisk of tw kernel)
be sure you have packages installed for build something like this, or edit or clone a github source. look at cm kernel build guides.
1. Download build-s4-mini-kernel.zip [here]
extract it to root of your user directory (my is /home/proxuser/)
2. We need toolchain 4.7.4 by Christopher83 original thread [here]
download
arm-unknown-linux-gnueabi-linaro_4.7.4-2013.07-build_2013_07_12.tar.bz2
extract arm-unknown-linux-gnueabi-linaro_4.7.4-2013.07 folder to toolchains folder (home/yourusername/toolchains) and name it linaro_4.7.4
Download Build scripts from my source here
download:
- abooteur_3g.img
- abooteur_lte.img
- build_all.sh
- build_eur_3g.sh
- build_eur_lte.sh
- build_master.sh
- mkbootfs
- mkbootimg
and put them to your kernel folder "root folder of your kernel".
if you want clone a kernel source: example CyanogenMod's cm-10.2 kernel then
open Terminal, and be in user root folder /home/yourusername (just open terminal and your there)
Code:
git clone https://github.com/CyanogenMod/android_kernel_samsung_msm8930-common.git -b cm-10.2
if you want clone my Kartal kernel then
Code:
git clone https://github.com/proxuser/kartal.git -b master
it will named "if you cloned cyanogenmod kernel android_kernel_samsung_msm8930-common" if you clone my kernel then it will named "kartal"
you can rename kernel folder, its not problem.
if you want change of kernel name(example kartal), then go yourkernel/arch/arm/configs/kartal_defconfig and edit CONFIG_LOCALVERSION="-Kartal" change only "Kartal" for your kernel's name. if you want change defconfig example "kartal_defconfig" to "yourkernel_defconfig" then you need change it in build_master.sh too that it builds with your config file.
if you downloaded your kernel source and your build tools are there then lets start
Open terminal
type
Code:
cd yourkernelfolder
for build both phones i9195 & i9190
Code:
./build_all.sh
if it denies access for build_all.sh then type
Code:
chmod 777 build_all.sh
you can give all files access with this command.
for build i9195
Code:
./build_eur_lte.sh
for build i9190
Code:
./build_eur_3g.sh
finally it will start building. it will done within 4-5 min. depend your pc speed.
after it builds succesfully, your kernel will be in your /home/yourusername/Packages/ folder
IF YOU WANT add new changes from CM or other kernel to your kernel
then open Terminal
cd yourkernelfolder
git remote add CyanogenMod https://github.com/CyanogenMod/android_kernel_samsung_msm8930-common.git
git fetch CyanogenMod
this will fetch CyanogenMod kernel changes but it will not apply to your kernel. you will add changes step by step yourself. copy commits SHA from CyanogenMod kernel and
open Terminal
Code:
git cherry-pick 2108e6c3109ae126590a81876145a1f17d6771b5
if you get success on pick a commit then you will get a message like this
Code:
[email protected]:~/kernel$ git cherry-pick a41564437a0eb910d0347d274456f3f0116c3c77

if you get an error like this
Code:

error: could not apply 63ee354... ARM: 7809/1: perf: fix event validation for software group leaders
hint: after resolving the conflicts, mark the corrected paths
hint: with 'git add <paths>' or 'git rm <paths>'
hint: and commit the result with 'git commit'
thats mean it is not applied to your files. just type "git status" to see what files are not modified.
then type: git reset --hard for go to your last commit.
this will make changes of error commit back.
Work always with git because with this way you can save a lot your changes and you can restore anything anytime.

Srry wrong topik..

I have built your kernel successfully, but after flashing the .zip the device is stuck on the "Samsung Galaxy S4mini" Bootscreen.
I tested it with the this two roms:
- cm-10.2-20131102-SNAPSHOT-M1-serranoltexx
- CARBON-JB-UNOFFICIAL-20131026-1327-serranoltexx
Do you have any idea why it's not working?
Edit: I used arcos source and it is working fine now

@junkyde
Can't get the stock kartal kernel to build.
What for OS are you running in your virtual box? ubuntu? 86x or 64x?
Did you install any other buildtools?

there isn't a stock kartal kernel. kartal kernel is aosp. I am using Linux Mint 15 in a 64bit version on Virtual Box.
Ps: I had also my troubles with ubuntu x86 and x64, thats why I switched.

Got it working under Ubuntu 12.04 64bit.
Had some troubles because mkboofs and mkbootimg could not be found.
After installing : "sudo apt-get install ia32-libs" everything was fine
Now I will try to compile the 10,1 kernel from source, lets see how that goes..

Yes I know, that this is required, when you are working with a 64bit system. But I couldn't get this installed in Ubuntu. On Mint everything worked fine. But I am glad you made it

@junkyde
After some trial and error I've succesfully compiled the cm 10.1 kernel.
Can you give me any direction on how to compile the custom liblights?
Do I need to download the full cm 10.1 source?

I used proxusers tutorial on how to build carbon rom. Downloaded full rom, modified lights.c and compiled whole rom.

Can someone build a kernel for the i257m
It would be nice if there was some kernel mods for this. especially just a near stock one with insecure root permissions.

yes you need custom liblights for BLN, but since I have compiled them already, you can use the one from inside the .zip of my kernel.

Forgot to add, I'm downloaded the cyanogenmod kernel from build 10.1 since that's the cyanogenmod version I use and for the one I need to make this mod, could this be the cause of the problem? Googling it seems that the kernel version you use may need a specific toolchain version.

I'm not using kartal but the one downloaded from cm. Thought the instructions were generic and the script took into account wether you had downloaded the kernel from cm or kartal :/, I did go inside the directory with all the defconfig files, how do I know which one should I point it to on cm-10.1 kernel?
Regarding the lights.c then I just have to include that library on the same directory you put it in your kernel AND add the changes you pointed to here http://forum.xda-developers.com/showpost.php?p=49958578&postcount=215 and I would be set?

[KERNEL][ICS/AOSP] Electron Kernel [-O3][SM~4.9.3]

Just gonna keep this short for you guys. This device is pretty old, and really there isnt much development going on. I dont have the time to work on a lollipop port, nor do I really care enough to try. That being said, I've mixed NUK3RN3L and StarKissed into one kernel, and have added a **** ton of optimizations. The full changes can be seen in my source code HERE. Lets squeeze what optimizations we can out!
Code:
ifdef USE
export DISCLAIMER="Use at your own risk, I'm not responsible for any mishaps or damage"
else
export YOUR_LOSS="You're missing out!"
endif
Major Changes(simplified for non devs):
Improved Memory Managment
Improved Overall performance
Updated from GCC-4.4 to SM-4.9.3(Toolchain)

Well, no. But mine hasnt changed either despite it being correctly flashed. Im pretty sure its just a problem with the ROM not detecting the change in kernel. You can download trickster mod or a similar app to check from there.

I downloaded Trickster and it says the kernel is "Linux version 3.0.16nuk3l ([email protected]) (gcc version 4.4.3 (GCC) ) #3 PREEMPT Fri Jul 12"
Is that what it should say or something else? What does your's say?
Edit: I just reflashed the kernel. Same reading on Trickster. I'm beginning to think that it might be the ROM not displaying the kernel name. I'm running NuSenseRom Reborn 6.0. I THINK I noticed a difference but it might just be a placebo effect. Hahah.

I think it did take. My battery charged in 1/2 the time it normally takes.

happy new year 2015
hmm..what feature on this kernel?
thanks you for post new stuff here btw

Just discovered that WiFi is broken. Says "error" in main settings menu after attempting to turn on the service.

Device Tree, Kernel, Vendor for TB-8504f?

Looking for the Device Tree, Kernel, and Vendor for this tablet.
I am just learning. Is there a process for getting these from an existing tablet?
Thank you!
Darran

I found the device tree for the a similar tablet here:
https://github.com/Matshias/twrp_android_device_tb_8504x

Someone on reddit told me this:
If you can find something with similar specs and the same processor you can try adapting it to your device. The Samsung Note 4 and the S5 use the same sources with some minor adjustments. I've had good luck getting some kernel sources from Samsung just by contacting them and asking, but they're the only brand I have any experience with.
For vendor files you can try TheMuppets found here: https://github.com/TheMuppets
Or you can try to extract them yourself using this guide- https://wiki.lineageos.org/extracting_blobs_from_zips.html
Best of luck to you.

Device tree and vendor are not the problem. Kernel source code is the thing that is required. Was going to buy tab4 10 but won't if lenovo is not willing to release the kernel source. I've repeatedly asked them to do so in the forums but they never reply. Maybe try mailing lenovo support and see if that helps...

thank you - do you know if they have a dev support e-mail or is it the standard support e-mail?

Your kernel sources are already available. Its included in the kernel of Tab 4 8 Plus.

Some things will match others need to be modified as per the non plus model. Vendor files can be extracted from the device and the device tree can be set up by referencing the plus model since they are not too different. As per the kernel try prebuilt first and see if it boots

Tab4 8 plus has snapdragon 625. Go to gsmarena and search by snapdragon 425 and you'll get a few devices then go from there and see if they have a custom rom. If they do then find the device tree for that device from github and modify it as required. For vendor extract it from the device. There are quite a few tutorials on xda. As for kernel download the one provided by lenovo for tab4 8 plus (it'll work for non plus model as well). As for defconfig extract it from boot.img again there are tutorials available.
I'll probably try to get los running on the tab4 10 later

https://github.com/redmidevs/android_device_xiaomi_rolex
I looked through muppets and didn't find any vendor files for the TB-850 or any TB devices. Will work on extracting the vendor files and getting them up on muppets. Can I use the extract-files.sh file from lineage to extract the vendor files for the TB-850?

A good choice. Vendor files should be from the same device like device tree.
Use this one:
https://github.com/redmidevs/android_vendor_xiaomi_rolex/tree/lineage-15.1
You need just the camera blobs blobs from your device. But you can do this later.
More important are the firmware files because those are unique for every device.
Replace thos files with the one on your device:
https://github.com/redmidevs/androi...tree/lineage-15.1/proprietary/vendor/firmware
I suggest you to build Lineage15.1 first. The kernel works with Android 8.1.

Thank you for the guidance - looking to give this a try today

I know this is not the place to ask but I haven't gotten any response from the places I was supposed to ask so bear with me
I'm building los 16 for lenovo tab4 10
I've setup the the device tree and vendor and am using prebuilt kernel but while building it stops at 69% with the following error

Soooo any ideas ???

Here are the repositories I am setting up
https://github.com/darran-kelinske-fivestars/android_device_lenovo_tb8504f
https://github.com/darran-kelinske-fivestars/android_vendor_lenovo_tb8504f
https://github.com/darran-kelinske-fivestars/android_kernel_lenovo_tb8504f

tb8504 kernel looks like can be built with this config https://github.com/HighwayStar/andr...rm64/configs/msm8937_p3588_pcb-perf_defconfig Changes after splitting can be intergrated in 8953 kernel from lenovo-devs org.
vendor blobs and common device tree can be used from here https://github.com/lenovo-devs only some hals has to be renamed or replaced with ones name msm8937 instead of msm8953
