Not sure of those of you who are familiar with the Barnes and Noble nook HD Plus reader. It was and is a good buy with excellent resolution. Only problem was the Barnes and Noble iOS that came with it. They did offer Android as well but the device after a while seemed to constantly reboot without notice. I discovered a link where you could get rid of the Barnes and Noble iOS and put on Android lollipop. I did it I am completely satisfied just thought I would share. Here is the link below if anyone is interested How to install Android 5.1 on a NOOK HD or NOOK HD+ - Liliputing
Cool deal, now all I have to do is think about rooting it, but is that really something I need to do?
You should be fine. Is the 12.1build stable? I'm still using 10.2.1; I tried 11 but had to reinstall the older version as it just rebooted continuously.
