one of the screw hold breaks and I can't turn on the phone
My iphone 6 has a long time problem with the display, some time it turns on when I pressed the power/home button but some time it doesn’t, while the sound and touch id all still works normally, so I suspected that it’s just a loosen cable problem.
So I opened the phone and unplug and replug the cables, but then I broke one of the screw holes when I try to put back everything, and now I can’t turn on my phone. Some searching shows that the screw hole that I broke was responsible for the power supply. How do I fix this?
