iPhone 4s start problems. The display stays black after the battery change.
Hi,
I've got iPhone 4s start problems (iOS8.1.3).
The display stays black after the battery change.
While loading it vibrates every 5 seconds.
I can see the iPhone on iTunes and i can reset it there.
But the screen is still black. I also proved the cable contacts.
Do you have any idea what could be wrong?
iPhone 4S, iOS 8.1.3
