view story

http://forum.xda-developers.com – Hi friends I was using stock firmware and recovery. I was wanted to use cm10.1. So when I went to recovery and tried to wipe data my phone took so much time it was not responding. After that I removed battery and tried to start the phone it was not starting only boot screen appearing. Than I again tried to wipe data through cwm recovery and the result was same. What can I do now??? (HowTos)
