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
full-fledged ROM developer.
ROM development normally
involves work from the ground
up and involves time , research
and patience .

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..

[GUIDE][MOD][KERNEL] Change Bootsplash Image

DISCLAIMER NOTE: I AND XDA IS NOT TO BE HELD RESPONSIBLE FOR ANY DAMAGES THAT YOUR PHONE MIGHT INCUR DURING THIS PROCESS, I HAVE TESTED IT IN MY BEST KNOWLEDGE TO WORK FOR OUR DEVICE BUT JUST TO BE SURE, PLEASE PERFORM ALL NECESSARY BACKUPS FOR THE PHONE TO PREVENT ANY DATA LOSS, IF YOU HAVE THE NEED TO DISAGREE AND/OR FAIL TO COMPLY JUST DON'T FLASH IT AND GET ON WITH YOUR LIVES

This is for editing the bootsplash: the image wich is displayed while kernel is loaded.
For example in Samsung devices is the image which comes between Samsung Logo and bootanimation.
This change is made in kernel, so if you want to include this in your ROM you must include the edited kernel with it.
Pre-requisites:
1.-Android Image Kitchen (DOWNOLAD)(THREAD)
2.-edit image on windows Tool modified by me (DOWNLOAD)(thanks to championswimmer for this)
3.-I recommend Photoshop or similar software for image editing (GIMP or Paint are ok)
4.-I recommend to enable the file extension visualization in Windows.
Let's start!
1.-Take the boot.img of the kernel that you want to use
2.-Extract Android Image Kitchen
3.-Extract edit-image-windows.zip
4.-Put boot.img in Android Image Kitchen folder
5.-Now go to cmd and navigate to Android Image Kitchen folder
6.-Type:
Code:
unpackimg boot.img
7.-Now open windows explorer and navigate to *\Android Image Kitchen\ramdisk, look for a *.rle file and copy it. Rebember the name of the .rle file, you'll need it later.
8.-Paste the rle on edit-image-windows folder
9.- Open cmd, navigate to edit-image-windows folder and type:
Code:
rle2png nameoftthrle.rle 000x000
Where I wrote nameoftthrle.rle write the name of your rle and where I wrote 000x000 write your phone's resolution.
Example: for me, I have a GT-S6500D wich has a 320x480 resolution and the name of my rle is GT-S6500.rle so I must write:
Code:
rle2png GT-S6500.rle 320x480
10.- Open the .png file which is now on edit-image-windows folder with your image edition sowtware (I recommend Photoshop) and made the changes you want. In my phone, is only displayed on black and white, so it's useless to enable color mode.
11.-When you finished editing go again to cmd and write:
Code:
png2rle nameofttherle.png
Where I wrote nameoftthrle.rle write the name of your png.
Example:
Code:
png2rle GT-S6500.rle.png
12.-Now you'll have a file called nameofyourrle.rle.png.rle witch is the modified rle
13.-Go to *\Android Image Kitchen\ramdisk and replace the rle with the new one witch is modified.
14.-Now go to cmd, navigate to Android Image Kitchen folder, and type:
Code:
repackimg
15.-Done! rename the image-new.img to boot.img and flash it!

Nice work, wonder if it work on window64

You can now edit/split a ramdisk on your phone now. Apktool on android has boot.img/ramdisk editing functionality. And a whole bunch of others....
Download apktool on android from here:
http://code.google.com/p/apktool/downloads/list
Make sure you download the correct zip file for your phone... And the updated apk. Follow the installation guide the developer has posted.
Before you split the boot.img make sure you're running apktool on an ext4 filesystem. Move the boot.img to /cache/subfolder our something like that.... then you shouldn't have a problem.
EDIT:
If your ROM has SElinux integrated, make sure it's set to permissive before splitting the image file or you'll get sh-applet error.
Go into terminal emulator and type:
su
setenforce 0
Happy editing

I prefer using pc, mobile isn't good for image editing and boot.img is kernel, so just a little pediting will be a brick for sure.

and on x32 sys? it didnt worked for me. bootloop. anyway doing for the 2nd time now
Edit- it did worked. many thanks

So how do you put a modified kernel in a rom zip? I built a rom from source, and want to change the uninstalled kernel to my own. P.S I have a tool that does this and creates a flashable zip for you, if anyone wants it.

Great work!!!
Tried it on my SONY... - perfect! :good:
Thank you very much

Can you use an .elf or .sin file instead of .img?

I'm on cm12.1 and there aren't any rle files

im also on cm12.1 an no rle file

By using these tools Can I able to change my boot splash ( ASUS Boot logo) in my asus zenfone 5 ? If not, then please guide me so that i can change my ASUS BOOT LOGO with custom made boot logo.
Thanks in advance?

I can't help myself but this work looks very similar to @DooMLoRD work - even the script is almost the same. Only resolution variable added....

Steps 5 and 6 go together.
Extract the LIB folder of BASE ROM to anywhere you want. Then copy and replace the bolded files below to the PORT ROMs LIB folder.

[DEV] sdat2img 1.1 - img2sdat 1.7 ◦ Unpack/re-pack android DAT files

Introduction
You probably know already that starting from Android 5.x (Lollipop) compiled roms (aosp,cm,stock) are not compressed anymore the way they used to be on previous android versions. On previous versions all content inside /system folder that has to be extracted within our device was either uncompressed (simple /system folder inside our flashable zip) or compressed in a system.img file, which it is a ext4 compressed file; both of these, anyway, were readable and we could see all system files (app,framework, etc).
The problem comes in >=5.0 versions, this method is not used anymore. Why? Because roms started to be always larger, so it is necessary to compress them even more.
What does new Android zips (full roms, but also otas) contain?
New Android flashable zips are made this way:
boot.img (kernel)
file_contexts (selinux related)
META-INF (folder containing scripts)
system.new.dat (compressed /system partition)
system.patch.dat (for OTAs)
system.transfer.list (see explanation below)​
What does updater-script contains then?
The updater-script uses a brand new function: block_image_update(), this method basically decompresses necessary files inside the device. Let's study it.
From google git source code, if we go inside the new file /bootable/recovery/updater/blockimg.c, we find at the end of it the registration of the function block_image_update() as the method BlockImageUpdateFn() which starts at line 254. Here finally we find all information we need to know about the decompression of the .dat file(s). First file we analyze is system.transfer.list which Google tells us:
The transfer list is a text file containing commands to transfer data from one place to another on the target partition.
Click to expand...
Click to collapse
But what each line means?:
First line is the version number of the transfer list; 1 for android 5.0.x, 2 for android 5.1.x, 3 for android 6.0.x, 4 for android 7.x/8.x
Second line is the total number of blocks being written
Third line is how many stash entries are needed simultaneously (only on versions >= 2)
Fourth line is the maximum number of blocks that will be stashed simultaneously (only on versions >= 2)
Fifth line and subsequent lines are all individual transfer commands.
Click to expand...
Click to collapse
Ok, but how to decompress the system.new.dat file?
All instructions are below. sdat2img, rimg2sdat and img2sdat binaries are involved. Please read carefully step by step.
NOTE for OTAs
If you are looking on decompressing system.patch.dat file or .p files, therefore reproduce the patching system on your PC, check imgpatchtools out by @erfanoabdi.
You can use/modify these files and/or include them in your work as long as proper credits and a link to this thread are given.
If you have questions or problems write here
Are you building from source and want to revert to the old flashing method without DAT files?

Ubuntu
Ubuntu 64-bit - Guide
Step 1 - Decompressing = DAT (sparse data) -> EXT4 (raw image)
We're now using sdat2img binary, the usage is very simple (make sure you have python 2.7+ installed):
./sdat2img.py <transfer_list> <system_new_file> [system_img]​- <transfer_list> = input, system.transfer.list from rom zip
- <system_new_file> = input, system.new.dat from rom zip
- [system_img] = output ext4 raw image file
and a quick example:
./sdat2img.py system.transfer.list system.new.dat system.img​by running this command you will get as output the file my_new_system.img which is the raw ext4 image.​
Step 2 - Decompress EXT4 (raw image) -> OUTPUT folder -> Compress EXT4 (raw image)
Now we need to mount or ext4 raw image into an output folder so we can see apks/jars etc.
To do this we need to type this command:
sudo mount -t ext4 -o loop system.img output/​As you can see there is a new folder called output which we can edit/modify/delete your files (not able to? see here)
Now we need to compress it back to a raw ext4 image, to do this we need the make_ext4fs binary. Make sure you have the file_contexts file (taken from the Rom zip) inside the make_ext4fs path. Then type this (got issues? see here)
./make_ext4fs -T 0 -S file_contexts -l 1073741824 -a system system_new.img output/​You will get the new raw ext4 image called 'system_new.img' ready for the next step.​
Step 3 - Converting = EXT4 (raw image) -> IMG (sparse image)
Now we need to convert the ext4 raw image into a sparse image. For this you need img2simg binary you can find here (thx to @A.S._id).
The usage is simple:
img2simg <raw_image_file> <sparse_image_file>​Pretty self-explanatory, the output will be a new sparse image (.img).​
Step 4 - Converting = IMG (sparse image) -> DAT (sparse data)
Now we need the img2sdat binary, the usage is very simple (make sure you have python 2.7+ installed):
./img2sdat.py <system_img>​- <system_img> = name of input sparse image file (from step 3)
As you can see the output is composed by system.transfer.list, (system.patch.dat) & system.new.dat, ready to be replaced inside your Rom zip.​

We're now using sdat2img.py binary, the usage is very simple (make sure you have python 3.x installed):
sdat2img.py <transfer_list> <system_new_file> <system_ext4>​- <transfer_list> = input, system.transfer.list from rom zip
- <system_new_file> = input, system.new.dat from rom zip
- <system_ext4> = output ext4 raw image file
and a quick example:
sdat2img.py system.transfer.list system.new.dat system.img​by running this command you will get as output the file my_new_system.img which is the raw ext4 image.​
Step 2 - Decompress EXT4 (raw image) -> OUTPUT folder -> Compress EXT4 (raw image)
Now you should either move to Ubuntu x64/x86 or follow the 2nd step from the Ubuntu guide on cygwin 32 bit.​
Step 3 - Converting = EXT4 (raw image) -> IMG (sparse image)
Now we need to convert the ext4 raw image into a sparse image. For this you need img2simg binary you can find here (thx to @A.S._id).
The usage is simple:
img2simg.exe <raw_image_file> <sparse_image_file>​Pretty self-explanatory, the output will be a new sparse image (.img).​
Step 4 - Converting = IMG (sparse image) -> DAT (sparse data)
Now we need the img2sdat binary, the usage is very simple (make sure you have python 2.7+ installed):
img2sdat.py <system_img>​- <system_img> = name of input sparse image file (from step 3)
As you can see the output is composed by system.transfer.list, (system.patch.dat) & system.new.dat, ready to be replaced inside your Rom zip.​

i don't think so, though you can install ubuntu in a virtual machine as 64-bit and decompress there without problems.

Confirmed.
Works perfectly..
Thanks a lot! This will save a lot of time theming.. (pulling the system, settings, framework without having to flash the rom first)
Oh, just for s&g's i extracted ("decompiled") the system.new file, the files (app, prive-app, framework, media, etc) all got placed on my desktop -- i deleted the system.new file from the rom -- i then placed the folders and files that got extracted and placed them in the rom -- i flashed it -- it booted! lol.. didnt think it would... but anyways, there's that.
For those who want to try:
--- > its basically self explanatory.
- once downloaded (the link above) extract the contents from the zip (i just went ahead and extracted to my desktop)
- right click the linux penguin
- run as administrator - the window will pop up
- go to file > open image > find your system.new image (should already be extracted from the rom and placed on your desktop)
- click open
- you should now see your image (or path) in the windows -- double click them (i doubled clicked both the right and left side)
- now you should be able to see all the folders
---> if you want to extract those folders
- just go up to the top
- click save and choose an extraction (i chose Desktop)
Hoped i helped -- any questions or confusion, dont be shy to ask -- i probably went too fast, idk lol
Enjoy!

I can't get this to work at all. I'm using Win 7 Pro and I've actually used this app before with stock Nexus 7 factory images and it worked fine.. What file did you actually download? I d/l 2 different versions, one was beta 2.0 and the other was a zip that said 2.2.71 but the about on the exe says 2.1, which is the version I've been using for quite a while.
With the beta 2.0, there's not even an option to open a file and with the 2.1, it errors out every time. After opening system.new.dat image and double clicking, it just hangs and the program stops responding. If I try clicking on it and selecting save, it allows me to select a folder to save it in but I just get a dialog box that says saving files and then hangs at 24% every time, finally crashing with a Microsoft C++ runtime error.
Oh btw, you didn't go too fast LOL, this is really a simple app to use but it's just not working for me with these block image files. Maybe I'm missing something but it's got me scratching my head. :laugh: If you have any ideas, I'm all ears.

i downloaded the 2006-8-26 apparently -- didnt even look at that date either LOL

EDIT: Ok, i lied.. i just checked my trash.. i did download the lastest release .zip .. the 2271..

@webdroidmt @Incredible_Culp Download from here lol: http://sourceforge.net/projects/ext2read/

Maybe something with my PC setup or Win 7 because the 2006-8-26 version doesn't even give me an option for opening a file image. It actually loads up looking like an incomplete application, it's also a very small filesize. Did you just d/l the ext2explore exe, or did you also d/l ext2read2 beta zip?
