view full story

http://forum.xda-developers.com – Hi, I have a GT-I9100 SG II with no efs folder backed up. I flashed the ROM once. however the IMEI has now changed to generic 00499. When checked there is no .nv_data file present in the efs folder. Nor there is a nv_data.bin.bak file present for restoration. I also tried to go on the stock firmware and re-rooted the phone, however still same IMEI number. All functions work well. even I am able to make calls and receive it. However somewhere I checked that normally nv_data.bin.md5 is used to verify the checksum of nv_data.bin and dump all the information in nv.log files. Whe (HowTos)
