I decided a few weeks back to hard mod my device, I did so and when I went to put battery in, I accidentally put it in backwards because the case wasn't on to guide it the right way. Anyways I was recommended to change my daughter board. So I replaced my daughter board and now its doing something else. The light comes on, and stays on for about 2 seconds, then the screens flicker on for like 1 millisecond and there is a slight popping sound from the speakers, and then it shuts itself off. I've tried opening the device slowly and still nothing, can you tell me whats wrong now?
