Ive been having a very similar situation with a couple infuse mobos i have, but just similar in terms of charging. If i put an already charged battery on the t959v it will turn on and work just fine. It even recognizes the debbuging mode. In fact after i changed the charging port i applied the unbrickable mod to the mobo and it worked perfectly. But still, battery wont charged. The infuse mobos wont turn on they just get stock in a bootloop. So please if someone knows about some schematic made for this phone or knows the route for those 5volts please help me... I would like to at least check the closest pins where those 5volts are supposed to go before giving up with that phone.
