iPhone still not powering on (before and after battery replacement)
So I recently acquired an Iphone 3gs that did not power on. I do work for apple as an IOS technician, strictly firmware troubleshooting, so naturally proceeded through all the standard troubleshooting steps, home and power for 30 seconds plugged into usb-PC/Wall. After attempting the power reset I tried leaving it plugged in for awhile just to see if it was a drained battery. Cleaned the dock connector, tried different cables, etc etc etc.
A passed time of mine is replacing batteries and screens so I went ahead and broke it down and popped in a new battery. Still nada. Left it plugged in over night and the charger isn't getting warm at all. Kinda running out of ideas... I've narrowed it down to either the power IC or the dock itself. Thing about it is I can't really find any definitive way to determine if its either or outside of the fact I can't get any juice to it.
So, I was hoping somebody might be able to point me in the right direction or is it just a crap shoot with this sort of thing?
Is this a good question?
