Phone is stuck in the middle of booting up, on the "Droid" screen, just past the encryption password screen. Pressing and holding the power button re-boots, but it just gets stuck in the same spot. I cannot figure out how to factory reset the phone since it is neither "off" nor fully "on". All the other forums I've found suggest removing the battery, but this phone does not have a removable battery. How can I get past this stuck screen? If I can't do that, how can I factory reset the phone? I have not installed any custom ROMs or anything like that...
