    clean properly your unit, wash it and let it dry, reheat network parts, if still no signal change parts like, network ic or PA.

    Hi, u have hot air on hand? Hot air is used by technicians in a service center, if you have the knowledge to use it just set the settings of air and heat put flux on the part and heat it for 10 to 20 seconds, but if not, its not recommended for you, you may burn other parts or you may damage other parts or the board itself that will result in a condemned phone.
