Help me please, I rooted this device trying to make it better, then decided to send it back. Because I wanted it without the root when I sent it back, I went into Z4root 1.3.0 and pressed the Unroot button, then it said that the device was completely unrooted. I then proceeded into resetting it back to factory settings to get rid of any extra files, but now it wont respond! It's stuck at the unlock screen. The time still changes, so it's not like it's frozen, but I can't unlock it because it wont react to anything touching it. I'm really scared because I have to send this back, and now it is being unresponsive. Help please! Thanks.
