If you have an EFS backup, use it. If not take it to a service centre. Corrupted EFS is pretty hard to repair otherwise.

i went to service centre but they said motherboard needs to be replaced even though phone is working fine

just odin flash with the same firmware that u used previously and it will come back. Then if you wanna go back, just root, install Fireflash from playstore and flash old firmware without modem.

i have flashed the same firmware but it works for just a week after that it becomes unstable and i rarely receive network. I dont wanna root my phone
