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 I9100G. 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)
For I9100G, go to origi_app folder and delete apk and odex files of Maps, PhoneSky and VoiceSearch.
Select option 3 in Main menu (Deodex /system/app)
Once its done, select option 4 in Main menu (Deodex /system/framework)
DONE!!
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.

Building Kernel
Okay. Let's learn how to build kernel for our I9100G. 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 I9100G (Download HERE. Go to Mobile->Mobile Phone-> Select I9100G 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-I9100G_Kernel.tar.gz to /home/<your_name>/build_kernel/
Folder structure: /home/<your_name>/build_kernel/GT-I9100G_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).
I am providing my initramfs HERE. (You can use it as it is or modify it. But give credits to me. )
Extract the downloaded zip and copy it to /home/<your_name>/build_kernel/
Folder structure: /home/<your_name>/build_kernel/initramfs
Now the entire setup is ready. Let's start modifying kernel configuration.
Setting up kernel config:
Go to /home/<your_name>/build_kernel/GT-I9100G_Kernel/arch/arm/configs folder.
Copy t1_defconfig file and paste it in kernel root folder (/home/<your_name>/build_kernel/GT-I9100G_Kernel/).
Rename t1_defconfig to .config in kernel root folder.
Now open Makefile which is in your kernel root folder(/home/<your_name>/build_kernel/GT-I9100G_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="-I9100G-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:
Open terminal.
Go to path /home/<your_name>/build_kernel/GT-I9100G_Kernel/
Type make.
THAT'S ALL. YOUR zImage is ready and is available in /home/<your_name>/build_kernel/GT-I9100G_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 I9100G_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??
<b>Getting the system dump from the device:
</b>
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.
<b>Deodexing app and framework folders:
</b>
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.
<b>Creating various mods by modifying framework and system files
</b>
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 I9100G. 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.
<b>Modifying build.prop and adding tweaks
</b>
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
<b>
Making META-INF folder and writing an updater-script (edify scripting)
</b>
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-I9100G 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.
<b>Signing the ROM and making a flashable zip
</b>
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-I9100G. TESTED.
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.
For porting ROMs, refer THIS tutorial. (thanks and credits to ayushrox)
Give me your feedback so that I can improve this tutorial. And post here about how your custom ROM making went. All the best.

After deodexing, did you push deodexed app and framework folder back onto device? (third section of deodex post). If done, then you can apply themes to it, use apks of other roms and so on.

Building kernel section updated
Hi,
Building kernel updated in 3rd post. Start building your own kernel.
I developed a flashable zip to help configure dual boot. Zip is designed to be independent of ROM type, version and install method, whether by flashable zip, cloning primary ROM to SD, or in general copying a ROM system image to SD.
Then I overhauled this thread...
Config-Dual-Boot-v1.0-signed.zip: http://www.mediafire.com/?edgat0koyp7d33l
Backs up /sdcard[-ext]/Boot (if it exists) to /sdcard[-ext]/Boot.bak
Creates Boot/ROM1 and Boot/ROM2 directory paths under /sdcard[-ext]
Installs Script Manager on ROM1 and ROM2
Contains shell script “copy-boot.sh” to copy ROM boot partition to boot image file
Contains shell script “boot-rom.sh” to switch to boot ROM2 from ROM1 and vice versa
The updated “boot-rom.sh” script now features generic boot image directory names: Boot/ROM1 and Boot/ROM2, and automatically captures the SD Boot directory path (/sdcard for CM ROMs and /sdcard-ext for Blur ROMs).
Instructions:
1. Boot to ROM1 (emmc)
2. Reboot to CWM and flash: http://www.mediafire.com/?edgat0koyp7d33l . Doing so will backup any existing Boot directory under /sdcard[-ext] and push a new Boot directory containing empty subdirectories ROM1 and ROM2 and two shell scripts: copy-boot.sh (copy boot partition to image file) and boot-rom.sh (boot switcher).
In the following steps, the shell (sh) commands can be run using ADB (Android SDK Platform Tools), Terminal Emulator, Script Manager or other suitable app.
3. Reboot to ROM1
4. Enter: “sh /sdcard[-ext]/Boot/copy-boot.sh”. This detects which ROM is running, ROM1 in this case, and copies its boot image to /sdcard[-ext]/Boot/ROM1
5. Configure Script Manager to execute “sh boot-rom.sh 2” which enables booting to ROM2. But do not run this command until ROM2 “boot.img” is in place. We'll do that now.
6. Reboot to fastboot and connect phone to computer.
7. Enter: “fastboot flash boot boot.img” where boot.img is a boot image file modified to host ROM2 on SD. Please see my Auto-Modify Boot Image thread.
8. Enter: “fastboot reboot"
9. Enter: “sh /sdcard[-ext]/Boot/copy-boot.sh” as in step 4.
10. Configure Script Manager to execute “sh boot-rom.sh 1” which enables booting to ROM1.
More on configuring Script Manager:
Go to Settings > More > Advanced Options > Config > Home Directory. Set home directory to /sdcard/Boot. Then while still in SManager, navigate to /sdcard/Boot and press boot-rom.sh to configure. Valid arguments are:
Code:
blank: Reboot to current ROM
1: Reboot to ROM1 (emmc)
2: Reboot to ROM2 (SD)
3: Reboot to recovery
Press the “Su” box to run as root (note green symbol) and press “Save” at top right. Then press “Run” at top left to launch boot-rom.sh and reboot to the other ROM.
Place shortcut to Script Manager on home screen.
If all goes well, you can now boot ROM2 from ROM1 and vice versa with just a few screen taps.
This procedure was tested working with Neutrino V2.8 EE (CM) on emmc and NottachTrix 1.3.1 ATT (Blur) on SD.

Thanks a lot dude! Im going to try this!
how do you install two roms at the same time? i thought this was showing how to do that but im confused. how do you change the cwm zip installers to .img?
edit:: sorry i thought this was the other thread showing how to install a dual boot system but in fact its how to configure it to boot into them easier. sorry for the mixup ill defiantly read over your 1st thread
Note: Joker recommended as a refinement to place all apps in sdcard to keep apps common to both builds. Good idea.

Does this mean that across both on CM7 and CM9, the same apps will be installed? And if you install a new app, it will be seen in both CM7 and CM9?
And is data for apps accessible as well for both CM7 and CM9? So saving a data file with CM9 for example will be saved in /data and when I boot back into CM7, the same data I saved from CM9 will be there in CM7?
Lastly, did you manage to get that dalvik cache thingy working?
That's a lot of questions, but I hope you understand what I'm trying to say.
If it is, then WOW!

Thanks for the good questions. I haven't yet considered Joker's tip in detail as I spent most of yesterday writing this thread, researching other related topics (and watching Downton Abbey with my beloved wife ). But off the top, I assume that if a given app works on both ROMs, theoretically there should not be a problem hosting it and its corresponding data on the kitchen table (sdcard).
I guess one of the challenging questions is: Are there certain apps for which data should be kept separate to enable ROM-specific customization?
I just updated my thread with this...
"Alternatively (and actually preferred), you can extract the contents of this zip: http://www.mediafire.com/?0kdp4qvy6fv71kp to /sdcard. It makes ROM selections generic, and also fixes a problem with boot-rom.sh (Android shell apparently does not like trailing spaces in script files.) Then drop your boot.img files into /sdcard/Boot/ROM1 and ROM2 and you're good to go."
Cheers.

Then I overhauled this thread...
P990 ROM Converter
from New BootLoader to Old and vice versa
Actually this tool is Tonyp’s idea. All credits to him.
He asked me if I am interested in making a script and automating the rom porting from one bootloader to the other and he assisted me with all the changes that need to be done.
Due to different EOL (end of line) termination in text files between UNIX-Linux (LF) and windows (CRLF), I had to make bash (linux) scripts necessarily. The good thing is that the tool can be used in both windows and linux systems.Installation:
Download and extract the attached ROM-Converter-tools.zip package anywhere you like.
Download and extract in the same folder, a newer ROM-Converter-scripts.zip if exists.
For Windows systems only:
Install Cygwin following the instructions below:
Download setup-x86.exe from here http://cygwin.com/install.html
Attention!! Even if you are running x64 windows system install the x86 version. DO NOT install the x64 cygwin version because two binaries (mkbootfs.exe & mkbootimg.exe used to pack boot.img do not work properly).
Run the setup-x86.exe, when the list of packages is shown make sure you add the following:
Expand Archive and select zip & unzip to be installed
Expand Utils and select cpio to be installed
Expand Perl and select ‘perl: Larry Wall’s Practical..’ and perl_vendor to be installed
(If you are already using cygwin run setup again and add the above packages to be installed.)
For Linux systems only:
Download the attached linux-mkboot-binaries.zip (mkbootfs, mkbootimg), extract them in tool folder and remove the windows ones (mkbootfs.exe, mkbootimg.exe).How to use it:
Put the source ROM.zip(s) in the 'source_zips' folder (otherwise you’ll be prompted to drag n’ drop it in terminal)
Open Cygwin. Type cd (leave a space after cd) and type /cygdrive/c/dir1/dir2/../ROM-Converter-tools
where “c/dir1/dir2/../ROM-Converter-tools” is the full path of the folder you extracted the convert-tool package (e.g C:\dir1\dir2\..\ROM-Converter-tools) and press enter.
In case of long pathname, instead of typing the whole of it, use one of the following tips to easily change to tool's path.
Tip#1: After you type cd , drag n’ drop from windows explorer into cygwin terminal, the folder "ROM-Converter-tools" and it wiil automatically be converted to ‘/cygdrive/c/dir1/dir2/../ROM-Converter-tools’ press enter and that’s it.
Tip#2: After cd /cygdrive/c/ type the 1st one or two letters of the next subdir and autocomplete it's name with TAB.
Type one of these commands in cygwin terminal:
Code:
./convert_rom.sh -stepmode #--> starts in step-mode for debugging purposes
./convert_rom.sh #--> runs unattended (with no pauses).
What it does:
The scripts use as input the 'files2convert.txt' which contains all possible files needed to be converted.
This is for compatibility purposes to support as many roms as possible and for future changes.
files2convert.txt
Code:
/ramdisk/fstab.star
/ramdisk/fstab.p990
/ramdisk/init.cm.rc
/ramdisk/init.cm-star.rc

/system/etc/vold.fstab
/system/bin/setup-recovery
/system/bin/check_sdcard.sh
/META-INF/com/google/android/updater-script
More files can easily be added for conversion if needed.
The converter:
Extracts source ROM zip
Unpacks the boot.img
Reads the above files, replacing partitions' mount points, among some othe things, for the selected bootloader
Replaces the kernel image for the selected bootloader
Builds new boot.img
Creates new converted ROM zip
Under 'kernels' folder there are already included the two latest Kowalski kernel images (zImage) for old & new BL and its modules.
You can add more kernels and you’ll be prompted to choose the desired one when converting a ROM (if more than one is found ).
Read how to do this:
kernels folder contains all kernel images (zImage), kernel modules and any other file the kernel needs.
for each kernel there are:
file(s) named: prefix-KernelName[-ver].zImage
folder(s) named: [prefix-]KernelName[-ver]Kernel
where:
prefix must be oldbl or newbl (depending on which bootloader this kernel is for.
KernelName[-ver] is whatever you like [and optionaly its version].
zImage is the extension of the kernel image.
How to maintain kernels folder
A. Update existing kernels
Download the desired kernel package and open it.
Replace its kernel zIamge in kernels folder
Extract its modules and any other file needed and replace all existing ones
B. Add kernels
Download the kernel package and open it.
Find the zImage inside package and extract it into kernels
Rename it this format: prefix-KernelName[-ver].zImage
Create a folder named: prefix-KernelName[-ver]. It will be used to keep kernel's modules and other files needed. If this kernel is released for both bootloaders and its modules are identicaly on both bootloaders (like the existing kowalski one) then name the folder only KernelName[-ver] (without prefix).
Inside this [prefix-]KernelName[-ver] folder create a subdir tree lib\modules
Extract in lib\modules all kernel's modules from kernel package.
If any other file is needed by kernel then create it's subdir tree (assuming that [prefix-]KernelName is the system folder of the kernel package) and extract it there.
Attention: Current version will hopefully work on CM-based ROMs.
Stock based ROMs need more files to be changed, but they are not included yet, because I don't have the whole info needed.
Hopefully @rugglez or someone else will be willing to help.
Till then avoid converting stock-based roms, (or if you do try, then after converting replace the boot.img in converted rom and "system/lib/modules/*" at least with a working boot.img and modules from another stock-based rom, for this bootloader of course. This could work but I am not the expert to say)
ChangeLog:
Version 1.0 Aug 23, 2013
- The two convert2xxx_bl.sh scripts are now integrated into one script convert_rom.sh.
- The new convert_rom.sh also accepts an optional switch [-stepmode].
Code:
./convert_rom.sh -stepmode #--> starts in step-mode for debugging purposes
./convert_rom.sh #--> runs unattended (with no pauses).
- A technique added to preserve whitespaces in converted lines. So converted files keep margins and whitespaces of the source ones.
- Script checks whether source rom is a newbl or an oldbl one, displays an error message if rom is not for the expected bootloader and exits.
Version 0.3b Aug 23, 2013
-a typo fixed in converting scripts
Version 0.2b Aug 23, 2013
-liblgeril.so is also replaced with the one for the oldbl or newbl accordingly.
-A forced removal (switch -f) added when removing files and dirs just in case.
-Converted ROM name will be built automatically from the source name suffixed by -oldbl or -newbl accordingly. (If source rom's name contains 'newbl' or 'oldbl' it will be substituted by 'oldbl' or 'newbl' accordingly)
-Converted ROMs are now created under 'converted_roms' folder.
-Converting to oldbl: Files 'check_sdcard.sh' and 'lgdrm.img' are being removed if exist (as they are not used)
-Converting to newbl: Charger dependent images are also copied in ramdisk (not only the charger binary).
-Kernel modules will also be replaced with the ones coming with specific kernel image.
-Kowalski Kernel images & modules, in kernels folder, are replaced with latest ones dated:2013072013. (it was my fault, the previous ones were downloaded from "releases" download folder and were dated 20230303)
-Some changes in display messages.
Version 0.1b Aug 19, 2013
-1st beta version
I really don't want to have all of the credits.
While it's been my idea to create such a script and I provided the input on what needs to be changed by the script, I couldn't have done it on my own.
I both lack the skills(!) and time.
Steve would say:
Anyways, don't leech. If this helps someone, donations are appreciated:

Hi my friend,
First of all sorry again for deleted post(s)..
and thank you.
The "typo" is corrected. Actually it was not a typo but I have noticed that it happens when pasting text from another editor.
Which ROM did you try to convert?
battery charge script cannot be opened error??? On which step did it happen?
I don't try to open any battery charge script
Did you add any file in "files2convert.txt"?
Very interesting tool.
Last july 7th I asked you if this were possibile and didn't have any reply. Now I'm happy that Tonyp convinced you.

I just converted Avatar-3.1 from old to new. No errors at all.
I don't like the write-protected error: rm: remove write-protected regular file `out/ramdisk/charger'
So it tries after that to remove the out directory but of course it's not empty.
Well,
Remove out directory manually and try again from the beginning..
After step 5, Before you continue to next step try to remove the whole out directory manually again.
Try also to give your account full control to the converter's folder.
This problem seems to he a windows security permission issue. Are you an administrator on the system you use?
-------------------------------------------------------------------
Stock based ROMs need more files to be changed, but they are not included yet, because I don't have the whole info needed.
Hope @rugglez or someone else will be willing to help.
Till then avoid converting stock-based roms,( or after converting replace the boot.img in converted rom with a working boot.img from another stock-based rom for the same bootloader of course. This may work)
Try ONLY CM-based roms.
I forgot to write it in OP. I'll do it asap.

Okay, I just used the converter on Win8 x64 to create an oldbl version of my CM10.2 ROM.
I have uploaded the resulting zip here: http://tonyp.basketbuild.com/index.php?dir=main/CM-10.2/oldbl-untested-builds/
It is untested - so do a backup!
I will post the steps I took, this might help some people who never worked with tools like this.
Please try it out with different ROMs - and if the resulting zips work a) post that here and b) share the zip in the respective threads for others to use
If you have any erros post the complete cygwin output here.
To get it do a right-click into the cygwin window, then press Enter - it's now copied into the clipboard!
Okay, off we go:
Preparation (one time only):
Downloaded cygwin. and install it
The path C:/cygwin is perfecly fine.
Just press Next until you get to the paket selection, then use the searchbox to quickly get to the tools needed:
(just click once on it, the first checkbox will get checked. The second one is for the sourcecode, you don't need that).
- zip (Archive)
- unzip (Archive)
- cpio (Utils)
- perl: Larry Wall’s Practical (perl) (you might have to open "perl" and look for it manually)
- perl_vendor (perl)
Downlaod the zip attached at the OP, extract it.
I extracted it to C:/temp/ROM-Converter-tools/
done
ROM conversion:
Open the Cygwin Terminal (either in the start menu or execute the Cygwin.bat at C:/cygwin/)
Put the ROM zip into the source_zips folder
Type:
Code:
cd /cygdrive/c/temp/ROM-Converter-tools
Needs to get adapted to your path if you extracted the ROM-Converter-tools somewhere else.
My path is: C:/temp/ROM-Converter-tools/
(Hint: after /cygdrive/c/ autocompletion with TAB will work!)
I didn't try the drag&drop tip of spyrosk.
Type:
Code:
./convert2old_bl.sh
(or convert2new_bl of course if you're going the other direction)
Follow the instructions on the screen,
As it's still in the debug mode you need to press [enter] a couple times.
This will change in the future.
Done, your converted ROM will be in the out_oldbl or out_newbl folder.
do this tool work with CM7

Hummmmm, I tried experimenting, and it happened to me the same as the partner "SREEPRAJAY"! ...
Here are the errors I had during the experiments (three files *. pdf);
Hrmph.
Was running the latest CM 10.1 nightly. Rooted, old bootloader, CWM Recovery 6.0.3.1.
Made a Nandroid backup. Wiped everything from recovery, factory reset, flashed this :
http://tonyp.basketbuild.com/download.php?file=main/CM-10.2/cm-10.2-20130821-UNOFFICIAL-p990.zip
According to CWM all flashed and well. I rebooted.
Phone's bricked, won't even boot to recovery, gets stuck in the LG logo. Ouch. Halp ?

I know ! ( NEVER flash anything as soon as you wake up without checking twice, kids. )
I saw the one for old bootloader for the 20th, moved up a directory, happily flashed the one for the 21th... and for the NEW bootloader.
Don't have access to a laptop to tinker and won't for a few days. Sigh.

No, and it never will.
GB relies on the old bootloader. It would be a lot of work to make it compatible, which isn't worth the trouble at all.

Ah that's a shame. spyrosk needs to have a look at that when he gets some free time.
You did a full wipe didn't you?
If you did it sound like an error in the fstab.

Your partitions are borked and you will have to use nvflash.
I'm sorry about that although I don't really know how you came to the idea to try the untested oldbl builds when you got no PC around to recover.
This could have even happened with the correct rom - again, it is completely untested.

I did the full wipe (I checked: I used the ext4 full wipe zip by dr4go for the old bootloader, as I usually do, using CWM 5.0.2.8)
Let's get some custom ROM tweaking going on for our 6s!
Ahead of my own MoDaCo Custom ROM for the 6, which is coming soon, I've created a custom ROM starter template for anyone who wants to have a go. It's a bit different.
Basically, this ROM template will let you create your own custom ROM VERY easily. Easier than ever before. All you have to do is...
download my ROM template zip
make the changes to the system of your phone just as you'd like them for your custom ROM
run some commands on your device via ADB
add the resulting files to the template zip
That's it! No messaging around with install scripts, no rebuilding anything complex, just mod - and go!
Preparation
ONLY if you are completing the process for the first time, you need to set up a file on your microSD card - so launch and ADB shell and type the following commands...
Code:
touch /sdcard/exclude
echo app > /sdcard/exclude
echo priv-app >> /sdcard/exclude
ROM build
Once you have your system up and running how you want it, and you're ready to distribute it (just the system and cust dirs mind, it won't pull the data dir, so your personal data is safe), reboot to recovery, launch an ADB shell and type the following commands:
Code:
mount /system
tar -X /sdcard/exclude -zcvpf /sdcard/system.therest.tar.gz /system/
tar -zcvpf /sdcard/system.apps.tar.gz /system/app /system/priv-app
mount /cust
tar -zcvpf /sdcard/cust.tar.gz /cust
You'll then end up with 3 new files on your SD card - system.apps.tar.gz (which is apps and priv-apps from system), system.therest.tar.gz (which, as the name suggests, is the rest of the system partition!) and cust.tar.gz with is the cust partition contents.
Update the template zip with these 3 files and that's it. It's ready to distribute for people to flash via TWRP! If you have updated the boot image, you'll need to replace that too, the easiest way is to do a TWRP backup then pull that file from the SD card and drop it into the template zip as boot.img. That's really it!
I hope this inspires a few people to start playing around with custom ROMs for the 6.. more cool things coming soon!
Oh and the all important template file...
DOWNLOAD - r1-customromtemplate-honor-6-h60l04-mogolia-b820.zip [MEGA]
NOTE: You should not flash a template ROM onto a different version base ROM. You should always ensure you have a stock dload ROM to restore to if needed. Use at your own risk!
P
I'm not familiar with rom developement but I was told that custom roms were impossible for Honor 6. So is it now fully possible ?
Has huawei changed their policy about sources ?
Only stock based ROMs. Source is still very limited.

Thanks for your work.
One of the things I missed most since moving to Oreo and Pie on the Note 4 has been trying out the new ROMs without having to mess with my daily driver setup. After a ton of research and some training on building ROMs from source, I was finally able to make Android Pie boot from any slot on Dualboot patcher. *
What you need?
* An Android Pie ROM
* Android Image Kitchen (AIK)
* modified device tree binary (dtb)
* a text editor
* RAR or some other zip file manager.
Instructions
1) Download and extract AIK from https://forum.xda-developers.com/showthread.php?t=2073775
2) extract the boot.IMG from your ROM to the same folder where you extracted AIK.
3) unpack the boot image using the unpackimg.sh script. This will create a split_img folder and a ramdisk folder.
4) go to the split_img folder and delete boot.img_dt (or boot.img_dtb depending on which version of AIK you are using).
5) copy the attached dtb.img file to the split_img folder and rename it to the original file name (boot.img_dt or boot.img_dtb)
6) go to the ramdisk folder and edit fstab.qcom. change this line:
/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,barrier=1 wait,recoveryonly
To this:
/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,barrier=1,discard wait
7) still in the ramdisk folder, modify init.qcom.rc. change this line **:
mount_all fstab.qcom
To this:
mount_all /fstab.qcom
8) go back to the AIK folder and run repacking.sh. this will create a file called image_new.img.
9) rename image_new.img to boot.img
10) replace the boot.img in your ROM zip file with the new one you just created.
Now you can use DualBoot Patcher to patch the ROM file for any slot and flash the patched file.
Just a few extra notes here:
* I only built these images for Android Pie for Snapdragon Note 4 devices. Make sure you use the the correct file for your device.
** in step 7, I noticed that some ROMs have an earlymount flag. You must delete that flag, otherwise the phone reboots to download mode.
***If anyone has any ideas to make this a flashable process, let me know. I would push these change upstream, but I don't know know enough about Git to do that. And, I don't know if the other devs want these changes.
Ok, so that was the manual way, but these changes can also be added to the kernel and boot image files at the time you build your ROM. Here is where you make the changes:
In the kernel, go to the dts sources. The file to modify is this one:
kernel/samsung/apq8084/arch/arm/boot/dts/qcom/aps8084.dtsi
Find this section and delete it:
Code:
system {
compatible = "android,system";
dev = "/dev/block/platform/msm_sdcc.1/by-name/system";
type = "ext4";
mnt_flags = "ro,barrier=1,discard";
fsmgr_flags = "wait";
status = "ok";
};
In the boot image, there are 2 files to modify.
1) device/samsung/trlte-common/rootdir/etc/fstab.qcom
Change this line:
Code:
/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,barrier=1 wait,recoveryonly
to this:
Code:
/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,barrier=1,discard wait
2) device/samsung/trlte-common/rootdir/etc/init.qcom.rc
Change this line:
Code:
mount_all fstab.qcom
to this:
Code:
mount_all /fstab.qcom
That's it. Build the ROM and it will be compatible with DualBoot Patcher. Since those are common files across the TRLTE, TBLTE and DUOS devices, all of those builds will be compatible with dualboot patcher.
So, one more thing. There are limitations to what you can install with DualBoot Patcher. Most things are easy to get around, though.
1) Flashable zip's that use Aroma installer might not change their behavior after being patched, and might install to your primary ROM slot anyway. Just something to be aware of.
2) Any flashable zip that has a custom script for updater-binary will fail to flash after being patched. For example, all the MicroG installers that I know of use custom scripts instead of the real updater-binary.
3) you cannot install a patched Magisk zip. But, you can install the Magisk Manager in your ROM, tap the install button (and the next install button that shows up), choose "Select and Patch a file", then choose the boot image from the Multiboot folder on your internal storage (/sdcard). It will patch the boot image and leave a file called "magisk_patched.img" in your Download folder on the internal storage (/sdcard). Use TWRP to flash this file to your boot partition, then reboot. Open DualBoot Patcher, tap the 3-dot button next to the ROM name, and tap "Set Kernel" to replace the saved boot image with the Magisk patched boot image. Note: if you accidentally
4) Magisk doesn't do much. You can use it to grant superuser permissions, but modules only work on the primary ROM.
5) custom kernels probably include their own dtb files. Flashpoint is an example of this. You may have to update the zip to remove the existing dtb file and add one of the files attached to OP. Make sure you rename it to match the original name in the zip file.
I set up my primary ROM per the above instructions, installed it, and I am trying to get my secondary rom installed. Do I need to set it up the same way (it is a 7.1.2 rom). When I patch it (7.1.2) through Dual Boot and try to flash it I get the following error.... " Failed to create temporary image /raw/data/.system.img.tmp" and it fails to flash. I've tried setting it both as secondary and in slot 1.... Any help would be appreciated... Hopefully I am just missing something simple.

What Rom are you trying to flash? Do you have enough space available on system or cache to flash that Rom? If not, try patching it for a data slot instead.
