In case if you have flashed latest SuperMan-Rom V1.5.1 using TWRP 2.0.3-0, Then you may lost IMEI, baseband etc, You can’t even able to make or receive any calls. Baseband version is ‘Unknown’ and IMEI & IMEISV (slot 1 & slot2 ) are ‘Unknown’ too.
Caution:
You have to remember that do not use the wrong Samsung ROM in case you have use the wrong country origin from here then you may lost your network permanently. I always suggest to make a FFS backup before placing any ROM into your Samsung device. You need to make EFS backup before rooting your device.
