I moved the original files to the GSU folder in sdcard and then hitted restore, but didnt seem to do the trick
I have 4 files, csc_backup.tar efs_backup.zip, efs_backup.tar and efs_img_backup.tar, all given by GSU
csc_backup is about 6kb
efs_backup about 8mb
efs_backup.tar about 66.3 kb
and efs_img_backup.tar 291 kb
Im freaking out, I think I may have lost my imei, but I did those backups when I had imei
EDIT: I tried moving all of efs folder from efs_backup.RAR to system, but now GSU says "cant read nv data"
EDIT2: I moved from 4.1.2 to 4.3 back to 4.1.2 and maybe that was the problem. But I still have the original EFS v1 files.
