I highly doubt you did anything to it to make that happen, although its always a possibility. I had something like this happen to me, it wouldnt turn on for some damn reason, tried all you did, battery pulls, charging, etc, and it finally decided to turn on, and it never had the problem again. Id just keep trying everything you can think possible, maybe try going into recovery? (hold power and volume up/down) if you can get to that for some reason and it still wont boot after trying it, maybe you can stock it through recovery.

 

no problem. I was bored and creeping the forums, wanted to do something
