htc one failed to start up again after system update
so I installed the new system update for my htc one. And ever since then it has not been starting up again it will not start up or just start up to a point and then go *gray*. I have tried charging of course and have pressed the power and volume button until I got the Hboot menu but nothing there works. Neither does plugging it into the computer. I am very frustrated right now, anyone have any Ideas as to what I could do to make my phone work again?
