The new version I flashed was the same as the old as i found it with the CSC N7100BTUEMK2 on sam mobile.
I checked the IMEI and it says 00499010640000 in status menu which is different from the one under the battery.
I did not perform a backup of anything as I was not worried about losing any data.
Any ideas what has happened to it and how to get the IMEI correct again?
I understand this is something to do with an efs file but in what way it has become faulty from flashing the same rom I cannot decipher
Any help much appreciated!
