To build a custom ROM extract the source code from the ics.tar.gz file (I would recommend using a program like 7-Zip). Once you have done that take the System folder that should be in the source code you extracted, create a new folder called MyROM, and put the source code for the System folder in the MyROM folder. Next extract the boot.img file for your ROM by extracting the boot partition of your stock ROM, and place it in the MyROM folder. Third, take a working META-INF folder that contains the standard Android update-binary, and a working updater script for your device, and place the META-INF folder in the MyROM folder. Once you have the System folder, Boot.img file, and META-INF folder in the MyROM folder, use 7-Zip to create a zip file containing the MyROM folder. After this flash the .zip file you created in recovery and you should have a custom. First off, for building a custom kernel if you extract the kernel source from the kernel.tar.gz file using 7-Zip, there should be a read-me or other type of documentation describing how to compile the kernel source code you downloaded. If there isn't any documentation I recommend taking a look at this guide on building your first kernel. While these are just a general outline of what you have to do, if you have any questions feel free to ask .

I should clarify that the source does not always include the /system folder sometimes companies will provide this and other times they won't. The other way to get the /system folder is to use adb and pull the system folder with a command similar to:
Code:
adb pull /system
Also this is just one example of a procedure that could be used to build a custom ROM from the stock ROM that originally ships with the phone. The procedure for building Cyanogenmod for example or another AOSP based ROM would be very different.

So glad to see this thread. Mine is an alcatel pop 4 5051d. After extracting, i saw a .com file of about 650mb in size. Please, what do i do from here? d file: https://drive.google.com/uc?export=download&confirm=zM0d&id=0Byi69Jpw2ZDtcTFBX0FzMXBkajg

Hi all,
I am trying compile and build custom ROM from android source for nexus s.
In the custom ROM for example crespo.zip we have three files inside
*META-INF
*system
*boot.img
I have compiled a android from source , but i don't known which files are needed in "out" directory to make a zip file. i googled and found tools to extract boot.img file and repack it . I don't known what are the steps to follow to create a META-INF folder.
i already rooted my phone and able to install custom ROM .zip downloaded from cynogenmod.
But how to built our own custom ROM
Can anyone give the steps to follow after compiling android from source

Requirement to make a custom rom
*java jdk installed on your pc
*windows xp or 7.
*package given in download section
Who is this kitchen for ?
Those who are brand new to
creating custom ROMs and
want an easy place to start
learning
Those who just want to modify
shipped ROMs or someone
else's custom ROMs to their
liking
Those who are confused by all
those scripts and complex
commands required for
building and extracting
This is NOT a tool to
automatically turn you into a

Kitchen setup guide
setting up android kitchen
1.download all the three link and unzip kitchen.rar and cywin package.
2.open cywin_package then open folder Now, you can see 3 icons, a read-
me,a setup, and a folder. Choose
the setup. Here You will choose
install from local directory. Next,
Navigate to the the folder of
extraction of cygwin and choose
the folder Cygwin_packages inside
the cygwin extraction folder. Wait
for some time. Then, You will come
across a list of file. Click the 2-
circle-arrows,untill, it displays
“install”
After the procedure is complete,
run the batch file cygwin.bat . Now, minimise
it and copy kitchen folder,
Keep it in some location where you have installed your cygwin package open home/ajay-Pc(in my case this is administrator name of my pc)kitchen
Now, open the batch file window
and type
cd C:\Kitchen
Wait for some time and then when
the location the changed, type
./menu

now minimize the batch file and extract official rom and open pda there you will find system.img then extract it using magic iso or flash
the official stock rom using odin the take a nandroid backup u will get system.rfs.tar in your sd card extract it using magic iso then make a folder in called rom and open it. again create a folder called system and copy all data from system.rfs.tar which u have extracted(do drag and dropping).
Now copy meta-inf of any stock rom and copy and kernel to rom folder.
Now you will get two folder and one file in your rom folder zip the folder content and copy the file where you have installed cygwin/home/ajay/kitchen/original update folder.
now open command shell which you have minimized 1st create working folder then add root permission,deodex your rom.
and at last press 99 to build your rom..
note-if it ask you to change updater script to update script change it but dont forget to change it back to updater script.now you will get your rom in output folder copy it to your sd card flash it if error occur unzip the zip file and delete meta-inf and boot.img and again copy meta-inf of any rom and kernel to it and zip it..again flash the rom..

first off if this is a wrong place than sorry but ....i wanted to know how to add device support to the kitchen?? my device is GT-S6012 galaxy music duos) rooted .......does it use yaffs file system..........if anybody could suggest me a method ...........i also want to know the procedure to port cm or any othe custom rom as i am using the stock rom right now .....any help would be appreciated !!!! :good:
omkar333 said:
WARNING: If your device is not listed in post #1 of this thread, and it does NOT use a 'YAFFS'-based filesystem (e.g. usually only low-end devices use YAFFS), do not attempt to flash a ROM that you built with this kitchen. Instead, you must do the following if your device is NOT listed:
Create a file under the kitchen's /tools/edify_defs folder, with the name being the same as the value of ro.product.device (found in your device's /system/build.prop file).
If the stock ROM images for your device contain the recovery.img file, extract its files from the kitchen menu: Advanced --> Tools for boot image --> Extract from boot.img/recovery.img in any folder. Then, open up its ramdisk folder, and look for /system/etc/recovery.fstab or /etc/recovery.fstab or similar FSTAB file location. Open this file to find the mount points.
See the template file in the edify_defs folder to see how to set the mount points inside the file you created. Look at the other files in that folder for examples on how to do it.
NOTE: This method does not guarantee your device will work with your custom ROM, however. Some devices may require more steps than just the edify_defs file, but the procedure is outside the scope of this FAQ. Ask around in the XDA sub-forum for your device if you need further help.

[Guide]1-Minute Porting
1-minute Porting Guide(mediatek)
I will explain below the 1-min porting technique.If you understand whole thing then you can port a Rom in 1-mins=60sec....
But You need to setup few things which are quiet easy.
Four Things Needed:-
1)7zip (usually everyone of you have it)
2) Notepad ++( usually everyone of you have it)
3)unpack Scripts- Get From Here and click Here For Thread Link
4)Install latest Pearl From Here.
Now learn Using Unpack Script and setting Up ONE-TIME things:-
1)install Cygwin(linux terminal) (for setting up cygwin see my full guide to port rom here)
2)exrtact the Downloaded script under Home/Your_username/script directory of Cygwin.Here you have to make manually "script" folder then extract.
3)Now open your stock rom and get boot.img and put into unpack scripts folder under cygwin directory.
4)open cygwin and type" cd script " abd hit Enter.Now use this command to extract boot.img:-
Code:
./unpack-MT65xx.pl boot.img
5)Now Copy boot.img-kernel.img and boot.img-ramdisk to a separate folder for future use.And delete boot.img ,boot.img-kernel.img and boot.img-ramdisk to make folder clean for next use.
Start 1-min Porting:-
1)Open the Rom you wanna port with 7zip.(1sec)
2)Now drag and drop boot.img to scripts folder.Use this code to unpack-(6sec)
Code:
./unpack-MT65xx.pl boot.img
3)Now copy and replace boot.img-kernel.img by stock one which you extracted earlier and saved in seperate folder.(10sec)
4)now repack it by this command-(1sec)
Code:
./repack-MT65xx.pl -boot boot.img-kernel.img boot.img-ramdisk new-boot.img
5)Now yoy will get a new-boot.img file under scripts folder.Copy it somewhere else and rename it to only boot.img.Then drag drop boot.img to PORT Rom zip.(18sec)
6)Keep 7Zip opened and drag drop system/etc/firmware and replace from stock rom.(25sec)
7)Drag drop and replace whole System/lib/hw and system/lib/modules from stock rom.(32sec)
8)Now drag drop and replace full system/vendor folder and system/usr/keylayout/gereric.kl file from stock. (1sec)
9)Drag and drop build.prop to anywhere in PC and add below line-(38sec)
Code:
ro.sf.lcd_density=xxx
10)Put value of your screen dpi in place of xxx..(40sec)
11)Drag and put back build.prop in Port Rom zip.Flash it and check it.(45sec)

Ow nice guy, but this is for rom or for app or for rom and apps?
HELLO GUYS AND GALS WE HAVE NOW NOUGAT IN OUR HANDS GETTING PRETTY STABLE BUT THERE ARE PEOPLE WILLING TO PORT NOUGAT TO THEIR PHONES SO HERE I AM WITH A GUIDE THAT I MADE MYSELF WITH HELP OF @mshoaib7 TO PORT NOUGAT ROMS FOR LENOVO A6000 THIS GUIDE CAN BE USED FOR OTHER SNAPDRAGON DEVICES
LETS START
BASICS---
YOU CAN ONLY USE 7.0 AS BASE FOR 7.0 ROMS AND 7.1.1 AS BASE FOR 7.1.1 ROMS
YOU NEED TO HAVE ATLEAST ONE FULLY FUNCTIONAL NOUGAT ROM THAT YOU CAN USE AS BASE
THE PROCESSOR OF BOTH THE PHONES SHOULD BE SAME
SAME GOES WITH GPU AND SCREEN SIZE
THE ROM OF YOUR PHONE IS CALLED BASE ROM
THE ROM THAT YOU WANT FROM OTHER PHONE TO YOUR PHONE IS CALLED PORT ROM
ITS HARD TO MAKE IT NOOBFRIENDLY:silly::silly::silly::silly:
REQS---
1] AUTO TOOL UNPACK REPACK TO EXTRACT SYSTEM.NEW.DAT FROM HERE
https://forum.xda-developers.com/general/general/tool-auto-tool-unpack-repack-rom-t3278393
2] WINDOWS PC
3]NOTEPAD++
4]TIME AND PATIENCE
LETS START NOW---
1] EXTRACT YOUR BASE ROM AND PORT ROM TO DIFFERENT FOLDERS
2]YOU MAY GET SYSTEM.NEW.DAT IN BOTH ROMS IF YOU GET THAT USE AUTO TOOL TO EXTRACT THEM
3]NOW GO TO PORT ROM FOLDER AND DELETE META-INF, FILE CONTEXTS, RECOVERY, SUPERSU OR ANY OTHER FOLDERS PRESENT
DONT DELETE BOOT.IMG AND SYSTEM FOLDER
4] COPY META-INF AND RECOVERY FOLDER FROM BASE TO PORT ROM AT THE SAME LOCATION FROM WHERE YOU DELETED THEM
5] OPEN SYSTEM FOLDERS IN BOTH ROMS
6]DELETE BIN, ETC, TTS, ADDON.D, USR, XBIN AND recovery-from-boot.p FROM PORT ROMS FOLDER
COPY THE ABOVE FOLDERS AND FILES FROM BASE TO PORT ROM AFTER DELETING IN PORT ROMS FOLDER
7]OPEN LIB FOLDERS IN BOTH ROMS AND COPY AND REPLACE /DRM
/HW, /SOUNDFX FOLDERS FROM BASE TO PORT
8] COPY THE FOLLOWING LIB FILES FROM BASE TO PORT LIB FOLDER
LIBGLES*, LIBMM*, LIBHARDWARELEGACY, LIBRIL, LIBRILUTILS, libwcnss_qmi, LIBCAMERA*
9] NOW OPEN /VENDORS/LIB IN BOTH ROM FOLDERS AND REPLACE FROM BASE TO PORT ALL THE FILES NAMED WITH
libacutator*, libchromatix*, libmmcamera*, libril*,liboemcamera, libimscamera
10]NOW RENAME BUILD.PROP OF PORT ROM TO SOMETHING ELSE AND COPY YOUR BASE BUILD.PROP IN SYSTEM FOLDER OF PORT ROM AND OPEN BOTH OF THEM AND REPLACE THE ROMS NAME, ITS VERSION AND STUFF FROM PORT TO BASE BUILD.PROP AND SAVE IT AND DELETE THE PORT BUILD.PROP
NOW THE BOOTIMG PART----
USE THIS TO EXTRACT BOOTIMG---
http://www.mediafire.com/download/815a86r7ay5dh8r/bootimg.zip
EXTRACT THE ABOVE ZIP AND CUT AND MOVE YOUR PORT BOOTIMG TO THIS FOLDER
NOW IN this folder press SHIFT+RIGHT CLICK AND SELECT OPEN COMMAND WINDOWS HERE AND TYPE IN CMD-
bootimg.exe --unpack-bootimg boot.img
your port BOOTIMG WILL BE EXTRACTED NOW DELETE EVERTHING EXCEPT BOOTIMG.EXE AND INITRD FOLDER
NOW RENAME THIS INITRD FOLDER TO "PORT BOOTIMG"
SIMILARLY EXTRACT YOUR BASE BOOTIMG BUT DONT DELETE ANYTHING THIS TIME NOW GO TO THE PORT BOOTIMG FOLDER AND CUT init.environ.rc AND PASTE IT IN INITRD FOLDER OF BASE BOOTIMG
AFTER REPLACING THAT FILE RUN THIS COMMAND
bootimg.exe --repack-bootimg
YOU WILL GET BOOT-NEW.IMG
CUT IT AND PASTE IT IN YOUR PORT ROMS FOLDER AND RENAME IT TO boot.img
NOW SELECT ALL THE FOLDERS IN PORT ROMS FOLDER
INCLUDING META-INF, SYSTEM, BOOT.IMG, FILECONTEXTS, AND OTHER FOLDERS IF PRESENT AND ZIP IT AND FLASH IT VIA TWRP
NOTE---YOUR BASE ROM SHOULD NOT BE COMPRESSED IN FORM OF SYSTEM.NEW.DAT OR YOU WILL HAVE TO CREATE A NEW UPDATER-SCRIPT
I AM SURE THIS GUIDE WILL WORK FOR SD410, SD210 DEVICES
COMMENT IF YOU FACE ANY PROBLEMS
IT WAS A LONG GUIDE:silly:
ENJOY
it is good but it will create ril bug.

Great for ones who want to learn porting.
Sent from my Lenovo A6000 using XDA-Developers Legacy app
Thanks a lot brother. I got some question .
1. Can I take any A6000/+ Nougat ROM as base ?
2. Most of the ROMs available for A6000 doesn't come with system.new.dat file. So we don't need to extract anything ?
3. But if port ROM has system.new.dat file then we have to extract it first ?
