I rooted the thing back in Dec. 2012 when I bought it, and I haven't done anything to the OS since then, so I'm running whatever I found here at that time. Huh. Do I have to revert to stock in order to re-root with one of the new OS's? And, er, how do I reflash the gApps?
Sorry for the stupid questions, this is my first-and-only Android device. And might be my last. Or I may take the stupid NT back to stock and just use it to read, and buy a real tablet now that they've come down to a decent price.
