Phone works, but doesn't charge nor communicates with iTunes
Hey all, I purchased a faulty 4s 64Gb in beautiful conditions inside out. Wouldn't turn on thus I swapped battery and seen it booting to desktop and seems to work fine. Unfortunatly the Pc doesn't see it at all, although I tried with different cables, working fine with other iPhones. Charging is the second problem; it seems to charge briefly for a second then disconnetcs. I replaced the dock with a surely working one but it didn't make a change. It seems there's nothing left but the logic board. Anyone got some suggestion before I trash it ? Thanks in advance for help.
Is this a good question?
