HI
I'm a g. mini user and i wanna install cm 7.2. I have tried take a efs file backup with efs pro but I've failed. How can I get a backup? :crying:
efs backup is not required for installing cm7
if you have an operator specific phone then you will need the backup else you don't need
I never ever backed up efs folder ...
Is there any chance to restore it in recovery or any ?

Hi
After doing a nandroid backup with TWRP 3.0.0.0 for all partitions including EFS when trying to restore after booting up my device it I get an "invalid IMEI" error.
Looking inside the EFS folder I can see that most files are missing and only a default nv_data.bin has been created.
Is there another method to mount the efs.mtd.win file and copy his contents?
Or perhaps another method to restore it or at least understand why it's not restoring properly?
Thanks for any hint.
