I'm in need of some help. I replaced the digitizer and Screen as one new unit on my wife's LG G2. At first it worked except the microphone wouldn't work and the proximity sensor was an issue. I found the proximity sensor gasket still in the old phone, disassembled, re-assembled with the gasket. And now it won't boot. It's gets to the LG screen and turns off. When I plug it in to the computer or charger, it just repeats the cycle,…turns on, gets to the "LG" screen, then turns off again, and continues to repeat.
