Step : 1

Installing the JAVA JDK, Cygwin and Setting up the Kitchen

Before you do anything install the java jdk

 

->Download and extract the cygwin_packages.zip

>Run the set up(make sure there is no previous cygwin installation)<From Net>

Or

->Download the kitchen from above. Then, extract the kitchen's .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:\cygwin\home\Kabeer\kitchen

NOTE!! If your user folder contains spaces (e.g. C:\cygwin\home\Kabeer Khan\kitchen), then the kitchen will not function properly. Instead, copy it under C:\cygwin\home\Kabeer\kitchen.

<Note : Kabeer is User name of PC, You need yours>

>Now your ready to run the kitchen type:
those who have their kitchen like this C:\cygwin\home\Kabeer\kitchen use these commands given below

cd kitchen(enter)

 ./menu(enter)

You will see look like this

Step 2

Download Recovertool zip File Here : Download Now

After Download Extract Recoverytool.zip file

Copy folder recoverytool to C:\cygwin\home\Kabeer\recoverytool

And Don’t touch red circle file and folder

And copy your recovery.img file in C:\cygwin\home\Kabeer\recoverytool Folder

Now Click Cygwin.exe file and type command

cd recoverytool

Step 3

Step 3.1 : Extract recovery's ramdisk (type command in Cygwin Terminal)

./split_bootimg.pl recovery.img> output.txt

Step 3.2 : Extract the contents of the ramdisk with (type command in Cygwin Terminal)

./unpack-bootimg.pl recovery.img

Step 3.3 : Edit the Ramdisk:

Type in Cygwin  terminal below command           

mkdir ramdisk

cd ramdisk

gzip -dc ../recovery.img-ramdisk.gz | cpio -i

cd ..

         <After this command you see ramdisk folder in recoverytool folder>

Step  4

lift the security default.prop

Original source code

ro.secure=1

ro.allow.mock.location=0

ro.debuggable=0

persist.service.adb.enable=0

Changed source code

ro.secure=0

ro.allow.mock.location=1

ro.debuggable=1

persist.service.adb.enable=1

Note : Change anything you want in ramdisk folder because ramdisk folder is recovery.img

Step  4.1

Pack-up Ramdisk

Type in Cygwin terminal :

./mkbootfs ./ramdisk | gzip > ramdisk-new.gz

<After this command you see ramdisk-new.gz file in recovery tool folder>

Step 5

Repack to IMG

Type in Cygwin terminal :

./mkbootimg --cmdline ‘mem=256M console=ttyS1,115200n8 init=/init mtdparts=sprd-nand:256k(spl),512k(2ndbl),256k(params),512k(vmjaluna),10m(modem),3840k(fixnv),

3840k(backupfixnv),5120k(dsp),3840k(runtimenv),10m(boot),10m(recovery),

100m(system),340m(userdata),10m(cache),256k(misc),1m(boot_logo),1m(fastboot_logo),

3840k(productinfo),512k(kpanic)’  --pagesize 2048 --kernel recovery.img-kernel --ramdisk ramdisk-new.gz -o recovery-new.img
