Hey all! I got this tablet about a couple of months ago and today, it was kind of jumpy acting so I turned the power off and turned it back on. Well, it won't turn back on! It just keeps saying Nextbook and trying to load =/ I tried holding the power button and volume button and it hasn't done anything thus far =/ it will charge, etc still. Has no cracks, scratches, etc! I have no idea why it will not work and would love for it to work again! What can I do?
