Phone was rooted and running 4.1.2 rom.
I flashed rom with official kitkat update N7100XXUFND3.
After flash, I had no service, and couldn't switch on WI-FI.
I rooted the using thread from smeet.somaiya and it went great.
Now phone is rooted, but I still same issue.
I didn't loose my IMEA after flash, and I have efs folde backup. i tried to restore it, bit still no service.
i live in Serbia.
Does anybody have some idea how to solve this problem??
