OK, So I've gotten to breaking down and recompiling those pesky .dex files, but I've run into a new problem.
This is a noob question, I'm sure, but .so files look like unformatted, binary files. How do I open then, edit them, etc? I need to read whats going on in my libs. :-(
Are these X11? I'm running ubuntu 10.04 x64 - so those could be difficult.
ie - unreliable 64 bit support.
$ sudo ln -s /usr/lib32/libX11.so.6 /usr/lib32/libX11.so

They're native library files, so platform specific machine code I imagine. Look for an ARM disassembler. I'm not familiar with linux internals, so don't know how you find the entry points, but it obviously will be widely documented. Is it impossible to obtain the source code? Assuming most are written in C/C++, reverse engineering from the machine code is not something I'd describe as a pleasant experience. If the source was well written assembly language & not too big, it can be almost enjoyable I guess. But then TBH walking through a randomly selected programmer's source, let alone object, files scares me, in a Tim Burton inspired bad trip kinda way. If you can find the source, it will be an order of magnitude less painful.
Try IDA Decompiler, it should disassemble all so files!
Most of the libs are open source in the aosp. Some are proprietary blobs with the only solution to them being reverse engineering.
.so disassembly
i know how to disassemble it
you will need orion's easy apk disassembler and apk manager
i've tested it once and it worked, but there´s a problem, i dont know how to re-assemble
1- rename the file .so to .apk like "libtestlib.so" to "libtestlib.apk"
2- put in the folder "place-apk-here-for-modding" of apk manager
3- open script.bat (or something like this) from Apk manager
4- use extract apk option
in the beggining my images inside the lib was corrupted so i used step 5 to fix
5- use option optimise images inside to fix images
6- go to project folder and copy classes.dex file to the root of easy apk disassembler's folder
7- open EasyApkDisassembler.EN.bat and use the "DISASSEMBLY a classes.dex with smali" option
8- give a name to the folder (like "libtestlib")
9- it will create a folder (like "out_libtestlib") with the disassembled files

Hi all,
In this thread, I will try to share the knowledge I have on deodexing, making custom ROMs, modifying initramfs, building kernel and much more.
Please check the below posts for each of these tutorials.
Hope this opens doors to many new ROM and Kernel developers.
NOTE: THESE TUTORIALS ARE WRITTEN FOR GT-I9100. WILL NOT WORK ON OTHER DEVICES. I DON'T TAKE ANY RESPONSIBILITY IF YOU MESS UP AND BRICK YOUR DEVICE OR ANYTHING ELSE. USE AT YOUR OWN RISK.
Deodexing Stock Rom
For GINGERBREAD ROMS:
What you need to have:
xUltimate v2.3.3 - you can download it HERE (Thanks and Credits to Xeudoxus for this awesome app)
Rooted kernel with busybox
JDK installed on your Windows system
If adb is not available in your windows PC, in xUltimate folder open "jar" folder. You'll find adb there.
Extract stock app & framework folders and Deodex:
Connect your device to computer.
Start xUltimate (double-click on Main.exe)
Select option 1. (Pull /system/app)
Once option is done, select option 2. (Pull /system/framework)
In the same folder, now you'll see two new folders (origi_app, origi_frame)
Select option 3 in Main menu (Deodex /system/app)
Once its done, select option 4 in Main menu (Deodex /system/framework)
DONE!!
NOTE: If any apk/odex gives issues while deodexing, remove that corresponding apk and odex from origi_app folder and deodex again. (Mostly the apps which can be downloaded from play store might give errors.. ex: Maps, Voice search etc.)
Now you'll see two new folders done_app and done_frame.
Push deodexed app and framework to device:
Connect your device to PC in USB debugging mode.
Copy done_app and done_frame folders to root of sdcard (/sdcard).
Open Windows command prompt and type the below commands.
Code:
[LIST]
[*]adb shell
[*]su
[*]stop
[*]mount -o remount,rw /dev/block/mmcblk0p9 /system
[*]rm /system/app/*.odex
[*]rm /system/framework/*.odex
[*]busybox cp /sdcard/done_app/* /system/app/
[*]busybox cp /sdcard/done_frame/* /system/framework/
[*]chmod 644 /system/app/*
[*]chmod 644 /system/framework/*
[*]mount -o remount,ro /dev/block/mmcblk0p9 /system
[*]sync
[*]reboot recovery
[/LIST]
In Recovery, Wipe Cache and Wipe Data/Factory reset.
Reboot.
Now you've deodexed app and framework.
For ICS ROMS:
For ICS Roms, the process is quite easy. (Thanks and Credits to jaydvn.)
Download the attached zip file.
Extract it on your windows PC.
Copy your /system/app to _app folder
Copy your /system/framework to _framework folder.
Run AutoDEOToolMain.bat
Follow the instructions.
deodexed jars and apks will be found in deodexed_APK and deodexed_JAR.
Push deodexed app and framework to device:
Connect your device to PC in USB debugging mode.
Copy deodexed_APK and deodexed_JAR folders to root of sdcard (/sdcard).
Open Windows command prompt and type the below commands.
Code:
[LIST]
[*]adb shell
[*]su
[*]stop
[*]mount -o remount,rw /dev/block/mmcblk0p9 /system
[*]rm /system/app/*.odex
[*]rm /system/framework/*.odex
[*]busybox cp /sdcard/deodexed_APK/* /system/app/
[*]busybox cp /sdcard/deodexed_JAR/* /system/framework/
[*]chmod 644 /system/app/*
[*]chmod 644 /system/framework/*
[*]mount -o remount,ro /dev/block/mmcblk0p9 /system
[*]sync
[*]reboot recovery
[/LIST]
In Recovery, Wipe Cache and Wipe Data/Factory reset.
Reboot.
Done.
Enjoy.
Building kernel
Okay. Let's learn how to build kernel for GT-I9100. There are many ways to build. I am just presenting here the way I build and make kernel.
NOTE 1: Follow the instructions exactly.
NOTE 2: Kernel is opensource. If you make any changes to it, you're expected to share your source. (Usually people share it over github )
NOTE 3: FLASHING KERNEL IS RISKY AND DANGEROUS. BE CAREFUL. BUILD AND FLASH ON YOUR OWN RISK.
What you need to have:
Ubuntu 10.04 and above (I use 10.04 )
ARM tool chain (Download HERE. Click on IA32 GNU/Linux TAR under Advanced Packages)
Samsung's opensource kernel for GT-I9100 (Download HERE. Go to Mobile->Mobile Phone-> Select I9100 (update 3 for Gingerbread and update 4 for ICS) and download the zip)
Setting up toolchain:
Extract the tar you downloaded(Suggestion: Extract to one folder where you can have everything. In my case /home/superatmos/build_kernel).
After extracting, you'll see a folder named arm-2010q1. Inside there will be many folders (ex. bin, lib and so on.)
Folder structure will be: /home/<your_name>/build_kernel/arm-2010q1
Setting up kernel:
Extract the zip you've downloaded from samsung's opensource.
You'll find two zips.
Extract GT-I9100_Kernel.tar.gz to /home/<your_name>/build_kernel/
Folder structure: /home/<your_name>/build_kernel/GT-I9100_Kernel
Setting up initramfs:
Samsung's zImage is divided into two parts: Opensource kernel (which you downloaded from samsung's website) and initramfs (which is root file system to boot up the device).
You can extract initramfs from your zImage using the below mentioned links (Credits and Thanks to Chenglu) Original Thread: HERE
To extract initramfs from Gingerbread zImage: HERE
To extract initramfs from ICS zImage: HERE
Folder structure: /home/<your_name>/build_kernel/initramfs
Now the entire setup is ready. Let's start modifying kernel configuration.
Setting up kernel config:
For Gingerbread:
Go to /home/<your_name>/build_kernel/GT-I9100_Kernel/arch/arm/configs folder.
Copy c1_rev02_defconfig file and paste it in kernel root folder (/home/<your_name>/build_kernel/GT-I9100_Kernel/).
Rename c1_rev02_defconfig to .config in kernel root folder.
Now open Makefile which is in your kernel root folder(/home/<your_name>/build_kernel/GT-I9100_Kernel/).
Modify the below lines (I guess line 195 and 196).
For ICS:
Go to /home/<your_name>/build_kernel/GT-I9100_Kernel/arch/arm/configs folder.
Copy u1_defconfig file and paste it in kernel root folder (/home/<your_name>/build_kernel/GT-I9100_Kernel/).
Rename u1_defconfig to .config in kernel root folder.
Now open Makefile which is in your kernel root folder(/home/<your_name>/build_kernel/GT-I9100_Kernel/).
Modify the below lines (I guess line 195 and 196).
Code:
ARCH ?= arm
CROSS_COMPILE ?= /home/<your_name>/build_kernel/arm-2010q1/bin/arm-none-linux-gnueabi-
Save and close.
Modifying kernel configuration:
Now open .config file(which you renamed). If its not seen, it might be hidden. Go to View->Show hidden files and there you go.
Do the below things:
Adding local version:
Change CONFIG_LOCALVERSION=" " to anything you like. I add this way:
CONFIG_LOCALVERSION="-I9100-superatmos"
Adding initramfs path:
You need to let kernel know the path from which it needs to take initramfs.
Change CONFIG_INITRAMFS_SOURCE=" " to ../initramfs (In this tutorial it's the path. If you had copied anywhere else, give the path properly).
Enough for now. Once you get experience, you can modify many configurations as per your liking and save. This configuration can be changed by GUI too with the command make menuconfig.
The Important part: Building the kernel:
For Gingerbread:
Open terminal.
Go to path /home/<your_name>/build_kernel/GT-I9100_Kernel/
Type make.
For ICS:
Open terminal.
Go to path /home/<your_name>/build_kernel/GT-I9100_Kernel/
Type export USE_SEC_FIPS_MODE=true
Type make.
THAT'S ALL. YOUR zImage is ready and is available in /home/<your_name>/build_kernel/GT-I9100_Kernel/arch/arm/boot/zImage.
Install the zImage on the device:
Go to the path where zImage is present and type the below line in command line.
Code:
tar cvf I9100_kernel.tar zImage
Flash the tar using odin.
DONE. CONGRATULATIONS. NOW YOU'VE YOUR OWN KERNEL.
Give me your feedback so that I can improve this tutorial. And post here about how your build went. All the best.
Making custom ROM
Let's move on to make a custom ROM.
Inputs/Feedback/Suggestions are more than welcome. Lets improve this tutorial together for the betterment of the android community.
Steps involved in making a custom ROM:
Getting the system dump from the device.
Deodexing app and framework folders.
Creating various mods by modifying framework and system files.
Modifying build.prop and adding tweaks.
Making META-INF folder and writing an updater-script (edify scripting).
Signing the ROM and making a flashable zip.
Folder Structure:
Before going forward, let's follow the below structure folder to make the tutorial more understandable.
Let our ROM name be CustomROM. The folder structure will be C:\Users\<your name>\CustomROM.
Let's move step by step. Are you ready??
Getting the system dump from the device
Click to expand...
Click to collapse
Make sure USB debugging is ON and connect your device to the PC.
Open command prompt on your windows PC and go to CustomROM folder path.
Type adb devices. You should be able to see the device detected. (If not check environmental variables whether adb is in system path or not. If not present, add the adb path.)
Type the below command to get the dump of system folder.
Code:
adb pull /system system/
Now inside the folder CustomROM, you should be able to see system folder with many folders like app, etc, framework etc inside.
Done with first step.
Deodexing app and framework folders
Click to expand...
Click to collapse
Look HERE how to deodex app and framework folders. Copy the app and framework folders to xUltimate folder, rename them to origi_app and origi_frame and follow the given link to deodex.
NOTE: After deodexing, merge origi_app folder with app folder under C:\Users\<your name>\CustomROM\system\app and origi_frame with framework folder under C:\Users\<your name>\CustomROM\system\framework.
Creating various mods by modifying framework and system files
Click to expand...
Click to collapse
Okay. This the section where your hardwork, innovation and talent comes in. You can use the mods available already, create your own mods, port various mods from other devices and so on.
Below is a list of various mods which can be ported on to GT-I9100. All the credits go these respective thread owners. Thanks to them.
Lidroid 14 toggle mod
Extended power menu with/without header
CRT Off Animation & SIP Over LTE/HSPA
Swipe to remove notifications
NOTE: Let me know more mods with links so that I can add here.
Modifying build.prop and adding tweaks
Click to expand...
Click to collapse
Okay. This is one of those files where you name your ROM(to be visible in settings. ) and add many tweaks.
To name your ROM (to be visible in settings), change the below code.
Code:
ro.build.display.id=CustomROM v1.0
Check the below links for many other tweaks. All credits go to respective thread owners. Thanks to them.
build.prop tweaks by TheFrankenstain
build.prop tweaks by dhlalit11
Making META-INF folder and writing an updater-script (edify scripting)
Click to expand...
Click to collapse
Once you're done with all the modifications, mods and additions, its time to create META-INF folder and make the updater script. Once the user flashes the ROM zip, this is the script that runs and does everything written inside the script. PLEASE BE CAREFUL WITH THIS. TAKE REFERENCE FROM OTHER (SAME DEVICE) ROMS' UPDATER-SCRIPT. (In this case, take reference from other GT-I9100 roms.)
Check the below links for tutorial and how-to on writing edify script and making updater script. All credits go to respective owners of the threads. Thanks to them.
Edify Scripting, Making Flashable ZIPs, ZIP Signing & Key Creation
Edify Scripting Notes
How to Write an Updater-Script with Edify Code
Edify Installation Script Syntax's
NOTE: system folders path, boot/kernel partition path, modem partition path and so on are COMPLETELY DIFFERENT for DIFFERENT DEVICES. Check the partitions for your device properly, carefully and then work on updater-script. TAKE HELP OR REFERENCE FROM OTHER ROM DEVELOPERS FOR YOUR DEVICE.
Lets move on to last step. Making a signing and making a flashable zip.
Signing the ROM and making a flashable zip
Click to expand...
Click to collapse
Make sure, now you should be able to find two folders (META-INF and system) inside C:\Users\<your name>\CustomROM.
Check in THIS thread for test signing your ROM. It WORKS with GT-I9100.
or Check THIS thread to create your own signing key and certificate.
Now you're done with making a custom ROM. Hope to see more custom ROMs from many users.
Give me your feedback so that I can improve this tutorial. And post here about how your custom ROM making went. All the best.

You're quite fast Updated Deodexing and Building kernel section..
Great thread Superatmos. I'll definately have a go at this.
Quick question ? Am i right in assuming that although your tutorial says to connect your device this line from xUltimate seperceeds that ?
"Alright xUltimate has been updated to v2 What this means is that you do not need your phone connect to your computer to deodex. So you can just manually place the .odex files in (\origi_frame\) and (\origi_app\) and it will deodex. You can also transfer the .odex files from your phone like the last version."
where do I get the zImage to extract the initramfs from? I can't seem to find the zImage on my phone or in the source anywhere.
Great
Very useful.. Added to my favorite.
Thank's man, i'll read that

Connect your device to the PC and double click Main.exe inside xUltimate folder. Follow the instructions you see from then. Its quite self explanatory.
If you already have origi_app and origi_frame folders, then just double click on Main Skip.bat.

Use ktool (available on market.. compatible with I9100) and click on Dump current kernel. You'll find it on sdcard.
One more way is when you download firmware from sammobile.com, just extract the file and you'll find zImage inside it.
Nice thread,
I m waiting from long time.
Thanks for your work.

I wanted to put this here as an FYI for anyone having trouble getting RemixOS to load from a Windows NTFS drive...
I was having trouble with this until I found that my "RemixOS" folder (that the OSs was being installed into) was a compressed folder. It had gotten created that way by the RemixOS installer. Note that Windows (in my case Windows 10) will sometimes create a new folder as a "compressed" folder, even if not requested to. (Perhaps it does this if there is less than a certain percentage of disk space.) The UEFI boot routines (that load RemixOS on EFI BIOS systems) do not handle compressed NTFS folders/files well. Once I decompressed these folders/files, RemixOS booted.

Hello once again my name is Cat Stevens and I have done it again you should check out my previous posts. But let's stick with the task at hand. I have been trying to upgrade the graphics for a while now and thanks to Android Kitchen I have been able to unpack and repack ramdisks and initrd.images as well. First you need libGLESv3.so you need to unpack system image of Android x86_64 7.1 with Remix Tools and you will find it in the lib64 folder. Then you need to get Android Kitchen and cygwin for Windows 32 bit is OK. Then copy the contents of the android win tools folder and paste them into the cygwin bin folder. Read the commands when you download the Android Image Kitchen. Unpack the ramdisk.img and you have access to the root of RemixOS. In notepad open init.x86.rc and go to line 11 and will see # export EGL_DRIVERS egl_dri2. Then add to the end of the line drm libGL /system/Lib/egl/libGLES_mesa.so /system/egl/libGLESv3.so eglIs&Lt:Resource>:Linked EGL_RENDER_BUFFER EGLDisplay . It's a long line and remember the path in the line because that is where you will need to install your libs. Then alter what ever else you want to the default.prop and repack your ramdisk. When you repack your left with a cpio.gz file you need to use mv command. This is the command mv ramdisk.cpio.gz ramdisk.img. Then you are done. Take care my friends if someone has a ADB binary for 6.0.1 let me know I want to get the VNC going.
Well somebody shut down my ramdisk hack it doesn't work anymore. Next I would like to thank the folks at Bliss ROMS for their hard work Electric Juses creative name. This is a MOD for RemixOS Hacked. I recommend installing Mount Image File and EXT4 driver for Windows. It gives you true ROOT! First download and extract Bliss ROMS x86_64 iso then mount your system image. Copy media_codecs and ffmpeg xmls. You will find them in the etc folder and paste them to your etc folder in Remix OS. Then go back to Bliss and open the vendor folder and copy bin, lib and lib64 folders and paste them to your usr folder in Remix. Then to tie it all together open notepad++ and create a text file you will save as userinit.txt. Then rename it to userinit no extension. This is the script.
#!/system/bin/sh
/system/usr/bin/rtk_attach
Their is the script now paste it to etc/init.d folder in Remix OS system image. Then go to the build.prop file and change persist.sys.disp_density=240 then change ro.sf.lcd_density=240. Unmount the image and boot Remix OS it will take a little bit longer than usual to boot but you will notice the difference with the display and audio. KILLZ! I recommend you should check out SET TV it's a APK file and for$20.00 US a month you get 500 channels and here is the kicker you can install it on three devices anyways I figured it out thanks again to Bliss ROMS and this will truly make your Android x86 system image The Green Machine!
This is your battery view when your device is turned off and plugged in.
This thread is Made for the S5 specifically (though these images can be used if rescaled to the right size.
The file can be known as Battery_scale.PNG
The file can be Located at. /res/images/charger
The file is a Multi surface image. Basically a zip png
To extract All the ".PNG" files use. https://github.com/Aaahh/Battery-Images-Replacer
Thanks to @Aaahh for making this a lot easier

Battery-Images-Replacer (forums.oneplus.net/threads/battery-charging-image-replacer.186460) is a way to easily change the battery boot animation. You can use Aaahh provided images or change them and make your own flashable zip. There are 2 problems in that solution, first it is directed to a specific platform (oneplus) and second, it does not work in Marshmallow (CM13).
I figured out a way to make Battery-Images-Replacer to work in Android 6 (Marshmallow) and problably in 5 (Lollipop). Just stating that I'm using CM13 in a Galaxy S3 (i9300) phone, but the code is the same one Aaahh provided with two minor changes:
The battery_?.png and battery_charge files are deprecared in 6.0, and replaced by battery_scale.png (multi surface image) with mandatory 6 frames (hardcoded in Android). To make Battery-Images-Replacer work with previous Android versions, the deprecated files are kept; and
The block device in anykernel.sh file needs to be generalized to work in i9300 (my case) and maybe others, so it was replaced at line 9 with: block=`find /dev/block/platform -name BOOT`;
Warning: be shure to do the 2nd step above, or the flashing will not work, but also, you may brick your phone!!!
But the catch is the creation of the new battery_scale.png file. In this case, we have the 6 single surface images (battery_?.png files) and want to make a "Multi Surface Image" file compliant with Android 6.0.
I made the following script (create_multi_surface_image.sh) that convert multiple PNG to a single "Multi Surface Image", you just need to change the FILES and SCALEFILE variables if needed. This script uses ImageMagick, exiftool and pngcrush to do the job. Just run the script where the battery_?.png files are.
create_multi_surface_image.sh
Once the battery_scale.png is created, you need to copy it to the Battery-Images-Replacer-ak-opo-anykernel/charger/ directory if you didn't run the script there. Go to the base directory (Battery-Images-Replacer-ak-opo-anykernel) and run "zip -r ../Battery-Images-Replacer.zip ." and you should get the flashable zip file at the parent directory.
Now transfer the zip file to your phone (adb push, usb file transfer, etc) and make shure that the file is available to TWRP ou CWM. Boot into recovery and flash the zip file. Turn off the phone and start charging. Enjoy your new battery animation.
I will attach the battery_surface.png file if you just want the final result using the source files (battery_?.png) provided by Aaahh and available at github.com/Aaahh/Battery-Images-Replacer.
Thanks Aaahh for the great job!
And what you have waited for
