first step is to clean the PCB used lacquer thinner to clean for about 30 minutes ..... after cleaning make sure phone is dry using hot air then .... check the phone if there a response in power supply using 4vdc ....if phone is not shorted try to connect it with JAF ...check if phone can connect with the BOX....

jut do that trick first do not make any HW action like reheating this or doing that....
