If I disconnect the “antenna flex cable”, this thing: Then the phone works perfectly. It charges and connects to the computer. I’ve cleaned this thing out thoroughly, cleaned the contacts, re-seated it multiple times. Yet, it will not work. I also can’t find much information on it. What does it do? Seems to be some component of the WiFi, yet the WiFi works perfectly on the phone with it disconnected. UPDATE: The phone would get real hot real quick even with this thing disconnected. Looks like the camera is heating up real quick real hot. Even when I replace it, it is quite hot.
