After installing April 2020 OTA update, my phone is showing no network connection. Everything else on this phone is functioning excellent. Both SIM cards and IMEI are appropriately recognized. I have tried all kind of reset offered by phone but without any success. The last straw was to try hard (factory) reset, but no solution. I have research any possible discussion on the Net but none has solved my problem. It seems to me that the modem process or its driver have turned zombie.
Model: SM-G950FD Any suggestion would be highly appreciated.
Here is the result that was found at hard reset screen, which I have found very common after the android 9 update but I am not sure if just this courses my problem:
#fail to open recovery_cause(No such file or directory)#

2. Check network operator settings Settings > Connections > Mobile networks > Network operators > Select automatically > OK > Registered on network.
Note: We recommend to set device network operators as LTE/3G/2G (auto connect) mode.

if you have read my post properly and completely. I have already mentioned I have tried everything including hard resets but nothing helped. The problem occurred after installing OTA update.
