Cannot register on network even after flashing successfully later

I am dealing with very serious problem with my phone. I was trying to flash stock ROM using fastboot. It failed, and start showing no sim card, empty IMEI, and no wifi either. I am finally able to fix it by flashing the modem partition, but still SIM cannot register to network.

When I go to manual network selection page, it search for them sucessfully too.

I am noticing two issues there:

A) It cannot register on any network

B) It don't list any 4G network.

How do I fix it. My phone is Lenovo P2.
