Create your Own Custom ROM an easy way


This tutorial is specially for
  • Newcomers to the world of Android 
  • People who want to create their own ROM but unable to do so as it is going over the head 
  • People who did not had any encounters with Programming
  • Even Experienced One 
  • dsixda for his ultimate kitchen
  • lokeshsaini who is the original writer i have just modified it and simplified for better understanding
  • Neroyoung -For his video tutorials
  • If i left any ones name PM me 
Tools Required : (Report me dead links please)
  • Java JDK Download Link-For Installing Cygwin
    Quote:
    (Note: Do not install Cygwin before the JDK!!
  • Android Kitchen Official Thread
  • Cygwin Link-Linux Terminal on Windows
  • Apktool/Apkmanager
  • Notepad++-For editing .xml files
  • 7-Zip-Handy tool

Part 1: Installing the JAVA JDK, Cygwin and Setting up the Kitchen.
*Before you do anything install the java jdk*
]

INSTRUCTIONS

->Download and extract the cygwin_packages.zip
-
>Run the set up(make sure there is no previous cygwin installation)

->when it shows all the package names, go to the top and select "all default" until it changes to "all install" (you must click on the arrows)


->Download the kitchen from above. Then, extract the kitchens .zip file to a folder under your home account. Rename the dsixda-android-kitchen-*** folder to just "kitchen". In Cygwin, this folder would depend on what was set for your Cygwin install directory, e.g. C:cygwinhomeJohnkitchen

NOTE!! If your user folder contains spaces (e.g. C:cygwinhomeJohn Smithkitchen), then the kitchen will not function properly. Instead, copy it under C:cygwinhomekitchen.

->Now your ready to run the kitchen type:
those who have their kitchen like this C:cygwinhomeJohnkitchen use these commands given below
Code:
cd kitchen(enter)
 ./menu(enter)
those who have their kitchen like this C:cygwinhomekitchen use these commands given below.

Part 2: Setting up a working folder

THERE ARE TWO METHODS FOR THIS.
1. WHEN YOU HAVE BASE ROM AVAILABLE.
2. WHEN YOU DONT HAVE BASE ROM.

FIRST METHOD -



->First our folder structure should look like this:
Code:
cygwin folder/home/your user name/kitchen
-> Inside the kitchen it should look like this:


-> Now we need a rom to work on, for KarbonnA5 users i will recommend this rom by ME only  but you can use any rom.

-> Just Place the original rom zip in the original_update folder inside the kitchen.
run the cygwin.exe again type:
Code:
cd kitchen(enter)
./menu(enter)
-> Now enter option 1, enter again. You should see your rom listed, choose and enter
you will be asked about changing the working folders name, at this point it makes no difference so just continue.

congratulations you have a working folder!!!



Second METHOD -it is almost like ROM Dumping works on any device!

Quote:
-> FIRST MAKE A WORKING FOLDER IN CYGWIN FOLDER
IT SHOULD LOOK LIKE THIS
cygwin folder/home/your user name/kitchen/WORKING_(your rom name)
NOTE: FOR THIS MEETHOD WE NEED 3 FILES AND FOLDERS TO BE PLACED IN WORKING FOLDER.
1. META-INF FOLDER - GET THIS FROM DOWNLOAD FILES LIST IN FIRST POST
2. SYSTEM FOLDER - TUTORIAL BELOW
3. BOOT.IMG - TUTORIAL BELOW

2. getting system folder
(NOTE - Rooted phone required!!)

This is universal method and can be done easily using terminal emulator.
For this simply download Terminal Emulator from Android Market.
we need freshly flashed device here. OTHERWISE YOU WILL HAVE LOT OF JUNK FILES.
Open it and type:

Code:
su
 tar -c system/* >> sdcard/system.tar
This will copy all your /system folder to your SDcard with name System.tar
This will take some time to finish so be patient.
After its done you should have a tar file in your /sdcard named system.tar
You can extract it using Winrar or 7zip software. But yes this will have huge size , as it has other useless folders so you will have to delete them. After extracting this system.tar file you will get following folders (Similar one)

Quote:
/etc
/fonts
/framework
/lib
/lost-found
/media
/sd
/usr
/xbin
build.prop
-> Now simply delete the folders marked in red color and its done.Dont worry if you dont have folders with red colors above,we dont need them.
And the final files that we will have in our system folders will be

Quote:
/app
/bin
/etc
/fonts
/framework
/lib
/media
/semc
/usr
/xbin
build.prop
NOW COPY THIS system FOLDER TO WORKING FOLDER

Quote:
3. getting boot.img

Here we have 2 options
1. stock boot.img from stock rom - simple kernel which we get in brand new mobile.
2. custom boot.img from custom kernel - kernel which are modified for overclock or other features

1. getting stock boot.img from stock rom.
extract your stock rom with winrar or 7zip. you will see boot.img there. copy it to working folder

2. getting custom boot.img from custom kernel.
download any custom kernel which is only for your device.
extract it with winrar or 7zip and copy boot.img to working folder
NOTE: many of new devices have kernel.bin and other files instead of boot.img so skip this part if your device dont have it...
Part 3 :Change/modify/update rom

[QUOTE]
  • Quote:
    YOU CAN MODIFY YOUR ROM IN TWO STEPS:
  • MODIFY USING ANDROID KITCHEN - for basic modification.
  • MODIFY MANUALLY. - for advanced modification.
Quote:

2. MODIFYING MANUALLY.

Check this Guide for some MODs like center clock,CRT animation, ics and jelly bean style mods etc...
[LIST][*]Adding/removing applications
1. Go to the working folder where you extracted your rom, inside you will find:
 OR 
2. Then go to "system/app" inside this folder you will find all the rom applications(apks) you may also find some in the data folder if your rom has this folder.
3. Copy, replace, and change any app(apk) be carefull if you dont know what the apk is do not delete!!
LIST OF APPS YOU CAN DELETE - HERE OR HERE
If you can not find some apps in this guide then try opening all those app in your phone and see app name and icon or move those apps from system/app to sdcard and see what is not working...
[*]Adding new boot animation
android kitchen doesnt works for my Karbonn A5 . So we need a different method.
1) Download and extract the bootanimation and samsungani file from Custom Booting.zip attached in first post.
2) Put them in the /system/bin folder and replace the existing files there
3) Now download any boot animation, and rename the bootanimation to “sanim.zip”.
4) Now, navigate to /system/media and replace the “ODEanim” with “sanim.zip”
You are done with the bootanimation change

[*]Edit the gps script for your country/location
1. In the workingfolder/system/etc/ you will find a file named gps.conf, you can
edit this file with notepad++ or even word.
2. using the right gps script in this file can speed up gps lock, you can
find some from angeldeath, download extract and replace the gps.conf.

[*]Adding ringtones :
  • Take your ringtone file...it should be in .ogg format..If not then convert it to .ogg..
  • Locate to the folder system>media>audio>ringtones>
  • Copy and paste your .ogg files here in ringtones folder..
  • You can also change notifications, alarm and UI tones like this..
[*]Changing the Fonts :
  • Take your desired font.ttf file and rename it as DroidSans.ttf..
  • Locate to the folder system>fonts>
  • Now, replace the file DroidSans.ttf with your desired DoridSans.ttf...
  • To change the lock screen clock font...replace the Clocktopia.ttf with your desired one..(rename first)..

build.prop tweaks!!
check this or this or this post for build.prop
NOTE: EDIT BUILD.PROP WITH NOTEPAD++. SIMPLE NOTEPAD WILL CORRUPT THE FILE.

Last but the not the least: repackage the rom

  • AFTER YOU HAVE DONE ALL CHANGE/MODIFICATION YOU WANTED OPEN CYGWIN AGAIN AND TYPE
    now convert update script to updater script(in option 23)
  • now lets edit updater script(optional)

    the updater-script basically tells CWM what steps to take during the installation(flashing rom).
    If you dont have any experience please dont edit anything other than what is in this simple tutorial.

    TO EDIT UPDATER SCRIPT -
    1.Go to META-INF/com/google/android
    2.Open the updater-scrip file with Notepad++
    3.Any text that would appear during the CWM install should be in this format :

    Code:
    ui_print("Put your text in HERE");
    Add your text start at top and save,
    then replace with new updater-scrip
