Black screen, keeps vibrating w/ power cable
I replaced the power button flex cable on an iPhone 5 because the button was not working anymore. I put the whole thing back together, but it won't turn on anymore. Nothing happens when I hold the power button.
When I put the phone on the charger, it starts vibrating every few seconds but doesn't turn on. When I connect it to my computer, the computer does recognize the phone, but the phone keeps vibrating and won't turn on. I had a spare battery, so I tried replacing that, with the same result. Does anyone have any idea what's up?
Is dit een goede vraag?
