Chosen Solution
a car run over my xiaomi pocophone f1, i replaced the screen(and frame) and then for few minutes anything seemed to be ok, but then i lost signal and had no network and cellular connection(the network sometimes works for a while and sometimes not). this IS NOT a software problem, and i’m pretty certain that this problem caused by damaged hardware. i opened the phone and inside everything looks fine and fully connected(antenna etc), but maybe my eyes are wrong. any suggestion what piece of damaged hardware can cause to no network from time to time?
If you opened and the Antenna Cables and Connections are good, Probably is a Problem with you BaseBand, check if your Phone has IMEI. Check BaseBand Chip area in the Motherboard looking for damaged components.
