What i tried so far
1. There are files is efs folder but not .nv_data file. I deleted efs folder from root of the phone and I changed nv_data.bak into .nv_data and followed the procedure of renaming that into nv_data.bin and so on but no luck
2. I tried efs professional tool but problem in creating archive .
3. I tried more than three stocks rom but no luck.
and than i thought it may be due to network lock issue but the personalizationb tab shows like this
so help me out
