SGS III have JB 4.1.1 (I9300XXDLI8) ROM/baseband, rooted with CF-Root/TWRP.
I was running the above ROM with some sort of (probably) Soft unlocking done by a local mobile repair shop. Anyway, recently I decided to try out one of the custom ROM i.e. Omega 32.1 (JB 4.1.1) and before proceeding any further I made a full backup on SD card with TWRP.
I downloaded and flashed Omega 32.1, thinking that I can always go back if something doesn’t work out. Anyway, long and the short of it, when I restored my S3 through TWRP restore, I found out that it isn’t connecting with my mobile network i.e. Warid Tel with the error “Not Registered on Network”.
By the way I also happen to have the factory unlock code for this SGS3, but unfortunately all the USSD codes I've tried to enter it, doesn't work.
Although, I guess I can take it back and get it re-unlocked again, but that isn’t going to allow me to install custom roms.
Can anyone guide me how to fix this situation, any tips, help, will be highly appreciated.
