So it's been a long sad story so far...
I have tried numerous different things, ranging from flashing the stock image for lollipop and marshmallow, and then installing nethunter, and so far, it works for a little while but then the tablet starts to become unstable, with "Unfortunately, XXXXX has stopped" which makes the tablet eventually reboot, and sometimes go into a boot loop.
Anyone else seen similar behavior?
Thanks!
