What is responsible is the network as it sounds like the have blacklisted your handset to make it work again you will need to change the imei number.

If phone receive calls probably is blacklisted.

Ok man ,

1 ) You must clean Antenna contact .
2) If u have the same problem , change the PA (power amplifier)

100% tested many times, Good luck.
