Efs partition on my tablet Samsung GT-P7100 (Tab 10.1v) damaged. Now I have IMEI - Unknown and Baseband - Unknown. I too have a file backup efs_backup.tar.gz
, which made early in the program GalaxSimUnlock
. I restored my efs partition perfectly using this backup file efs_backup.tar.gz
and program GalaxSimUnlock
. I see correct IMEI and Baseband values. But after reboot my tablet efs folder is empty again and I have again my IMEI - Unknown and Baseband - Unknown. Can anyone help me with this problem please?
