I had to perform a hard reset of my tablet. After booting up, the Google sign in screen appears. This is where I can login as a current user or create an account. There are 2 Google accounts that I've tried to use. Each time I use one and press NEXT, the tablet freezes up. I've also tried creating an account. When I enter the info and press NEXT, the tablet freezes up. I've tried resetting the tablet both while it is running and off, with same result.
It is an Android tablet. After I reset the tablet, it searches for software updates, so I believe it's up to date. Lollipop 5.0.1
After resetting the tablet, Google won't allow me to sign in with either of my accounts, or even by creating one -- it just freezes. I must reboot the tablet every time. If I skip the Google stuff, I can access the tablet, including using Chrome browser.
