@chongns u suggested to format data,cache,dalvik cache and system but there was one more option in mounts and storage (i.e.mount emmc and format emmc)should i have formatted that emmc also.and what was imp of the post u sugested before.

i also formated emmc but its of no use the apps are still force closing and data is not getting wiped.

sometimes after flashing and using the mobile for a while sometimes it goes into kernel upload panic mode.what is kernel panic upload mode and what causes it and how can i not get such a message.please help

i also tried to install miui v4 but it gives the same problem as as remics and cm9 it shows "Encryption unsuccessful"

I would said u having the partition corrupted. So it is wise send it service center than you corrupt it more further

http://forum.xda-developers.com/show....php?t=1736118

it have similar problem with you, you can have a look

after flashing value pack update for india it shows
E:failed to mount /data(No such file or directory) what does it mean and how to make it usable it is not working.please help

Are u facing a random reboot then you get to 'encryption unsuccessful' screen? Then a reboot would get you back to normal state? I solved this by flashing the value pack via mobile odin pro with ever root. I flashed the latest one by prezket
