Hi all, so i've been searching information on this case for more than an year, I just generally gave up solving it and just ****ed it but now I still want to try. The problem: I try to connect my iPhone 4 to computer trough a usb cable, it reconnects every 2 seconds, but is charging. What I know for sure: It's not the cable - I have tried 3 different cables. It's not the iPhone settings - it connects to my laptop and my office PC right away, not reconnecting even once. What I've tried and didn't work: - Reinstalling the Apple driver - Uninstalling the Apple driver - Reinstalling iTunes - Uninstalling iTunes - Resetting iPhone Location & Privacy settings - Resetting iPhone Network settings - Turning airplane mode on while connecting - Pushing usb gently till it connects, not through the whole way in - Turning PC off, unplugging all cables, pushing the boot button for 1 minute, switching it back on Something curious to know: My sister got iPhon6 and she tried to connect it to her PC. It was doing the same thing! And guess what? We have the same motherboards of our desktop PC and we ordered them from the same service. She said she solved it by blowing hard into the usb port. It didn't solve mine tough. If anyone thinks he can solve this, please go ahead. I gave up and just transfer my files trough my laptop. But it would be really nice If I could use my desktop PC too.
