Changed power button flex cable. phone wont turn on now.
So I was changing the power button flex cable on an I Phone 4 because the power button wasn't working as it wasn't clicking, nor was it even press able. So I changed it and all that, now nothing will turn on. I plugged the phone in to a charger and it was vibrating and making some noises, but the screen was dead. Nothing at all, not the apple logo, nothing. I tried a new screen, still nothing. I feel like the board just went bad.
Is this a good question?
