I tried flash using lot of different roms it' didn't helped.I had an issue recently where my efs was corrupted (my IMEI said unknown). I did not have a backup but a flash of the stock ROM from Samsung using Odin solved my issue. If that didn't work I was going to try a tool called EFS professional that might help you also.
