It does all the standard plain-vanilla Android things very well. Cyanogenmod 11 has been fiddled with and tweaked for months, and it’s in the position where Cyanogenmod 10 (Jelly Bean) was when I originally wrote the guide: stable, dependable, and more or less reliable. But if you actually depend on your Nook HD as your day-to-day Android tablet, there’s nothing at all wrong with Kit Kat. It would probably be best to try it only if you have a better Android tablet for everyday use and wouldn’t feel bad about messing up your Nook HD.

So, if you should want to see how well Lollipop works on this older hardware, by all means, feel free. However, a new version of it dropped yesterday, and after installing it, it seems to work a lot better now. Mini-Update (Sep 30, 2015): I’ve been trying out Lollipop on my own Nook HD for a couple of weeks now, and it was originally very sluggish-almost unusably so. The version of Nook HD Lollipop that just came out seems to be by a new tinkerer, and it’s very early days. I gather the person who did the last Nook HD version of Cyanogenmod stopped fiddling with it after Cyanogenmod 11, Kit Kat, which is why the Nook HD has gone so long without an edition of Cyanogenmod 12 Lollipop. New versions of it for older hardware nobody even makes anymore, like the Nook HD, are very much an open-source do-it-yourself project for tinkerers who feel like messing with it. Cyanogenmod is basically the shade-tree Linux distro version of Android, right down to having founded a commercial company that is doing its own weird and wacky things for newer hardware. That being said, the new update is a bit unstable and bleeding-edge. There’s now a Nook HD version of Lollipop Cyanogenmod available. Well, the good news for you is, now you don’t have to stop with Kit Kat. Even well after Barnes & Noble has moved on to completely different tablets, it seems there are still a lot of people out there who want to know how to upgrade their old Nook HDs to Cyanogenmod. But even over a year later, we still see it pop up regularly in our top-visited statistics from day to day. Update (Sep 15, 2015): When I first set out to write out this guide, I had no idea it would turn into one of our most evergreen articles.
