Hard reset doesn't work. Not charging & not responding to Itunes.
Iphone 4 went dead on battery level: 65%. Hard reset: not responding. Charged for hours but Iphone doesn't charge, not dissipating any heat, no noise. Connect to Itunes: Itunes doesn't recognised and not communicating with Iphone. Cleaned both 40 pin socket and jack. Tried putting the phone to DFU mode but not responding. Please help. I last backup the phone was 6 months ago.
Is this a good question?
