So I had cracked the screen on my vivid and ordered a new one from amazon to try and replace it. The process went pretty well except one of the flex wires (the one under the screen, beneath the lcd) looks like it got cut somehow. When I put my phone back together the lcd lit up for a couple seconds and vibrated and kept doing that over and over. So, a couple questions. What is the wire under the lcd for? And would that keep my phone from starting up? And if not, what else could it be? If anyone has any input it would be appreciated. Thanks!
