iPhone 4 won´t turn on after proximity sensor replacement
I replace a proximity sensor on a iphone 4 and after that it won't turn on. I tyed to install a new one and it won't turn on too. When I plug to charger it vibrate twice in loop untill I unplug charger. I tryed to dissasemble to know if something wasn't correctly connected but I didn't find nothing wrong. Someone knows what to do? Thank you
Is this a good question?
