I want backup my /efs partition to avoid mistakes if i flash new ROMs on my phone and I did read in the forums that some guys lost there IMEI number etc. because the /efs partition was deleted after flashed a new ROM. So now I want do a /efs backup to avoid this. But EFS Professional show the wrong partition of my /efs partition. It show mmcblk0p9 but DiskInfo show mmcblk0p11 (and i believe that mmcblk0p11 is correct).
I also did backup my efs via TWRP.
I have cyanogenmod 11 installed. Maybe CM11 cause this problem or have EFS pro a bug? I really want backup my /efs guys and I hope you can help me
Some infos about my phone :
Model number : GT-I8190
Cyanogenmod 11 installed
Baseband : I8190XXAMG4
Busybox version : 1.22.1
Problem solved : I made a efs backup via Terminal Emulator with success and it's much faster and it backup correctly than efs pro. Thanks to @tys0n for this trick
