[Q] will restore work?
Stock firmware N7100DXDLK5
Will restoring first full backup work to get back efs.
I was on N7100DXDMF2 when I made my first backup.
Eventually was advised by DR.Ketan to make a efs backup which I did but lost all saved files on pc.
However I had kept the full backup on my usb pendrive minus the efs backup.
After a long time on 4.1.2 I wanted to try out 4.4 kitkat at which time the imei/sn/service state and the mobile
network state were all intact.
Then tried out SupremeBean 4.3 and I think it was still okay since I had made some calls using said rom.
Then I opted to go back to 4.1.2 and all hell broke loose.
Lost mobile net.state/service state.Imei number 0049.....and the sn is different.
Do I need to flash back the original firmware i.e. N7100DXDMF2,Root,download a custom recovery like TWRP and use the old backup file.
Funny thing is, I could not find that firmware anywhere.And the stock recovery is being stubborn of not allowing other recovery to overwrite.
Maybe this has been answered a 100 times over but I think situations differ.Why, cos I still have a corrupted imei number and a serial number which is not far off from the original.
Any aid be much appreciated.
