Finally I have compiled a CWM RECOVERY 5.0.2.8 for KARBONN A21

AND IT IS FULLY WORKING

Pre-Requisites : Rooted Karbonn A21


Steps to flash the CWM Recovery :-
1. Download the zip from here or here
2. Extract the zip in a folder.
3. Copy the recovery.img to the ROOT o f the SDCARD. ( Root means not in ANY FOLDER )
4. Open any terminal emulator in your phone. You can try this
5. Type following commands :
su
dd if=/dev/block/mmcblk0p16 of=/sdcard/mmcblk0p16.backup bs=4096
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p16 bs=4096


The Recovery is flashed
Use the combination to enter the CWM RECOVERY.


Known Bugs :

Unable to go back[/B]


Thanks to : 1. I, me and Myself for taking the initiative and trying
2. altruist101 for the Stock Recovery
3. Cyanogen-mod for the sources
4. ankitmishra0411 for being a tester

For making it fully working someone has to come on chat.
I cannot correct it if no one is interested to have a CWM RECOVERY.
