I was following the "Idiots Guide 2.0 guide Install Android on HP Touchpad" (sorry I can't link since I'm a new user but I don't think that part is super important anyway). I didn't get very far. When I restarted the device and was supposed to hold the "Up" volume arrow, I accidentally hit the "down" arrow. Now my device won't turn on or respond to any buttons. What the hell did I do?
