try to rehot U103 and all of the component elements next to it from this schematic cause maybe the solder is dry for some component elements that can't transfer electricity properly so some fonctions can't work for your phone

roloseamerica, the question about unlocking is an important one but also cause your username is .......america. are u base in united states and phone from outside aka Europe? if latter is yea it might not have the necessary frequency support for 3g in your area
