I've recently factory reseted my Touchpad and removed CyanogenMod. All was good, and I was at the initial setup screen for WebOS. However, I never actually went through the setup and when I went back to the tablet hours later it shut off. It was fully charged. I try booting it up, and now it gets stuck at the HP logo and never loads passed that. What can I do? I've tried holding the power button and middle button, and a few different variations, but no luck.
