I have little knowledge on how to get this rom working. If someone would like to take over then start a new thread. On top of this, it's currently unclear the state of the Ubuntu Touch project as a whole.
Welcome to Ubuntu Touch for Nook HD
Ubuntu Touch is a project from Canonical that aims to create a mobile, touch friendly, unique operating system.
I DO NOT claim to know what I'm doing, half the time I do not, lol.
Installing/flashing anything discussed in this thread is at your own risk. Things break, code is never 100% perfect, I'm not responsible if your device is bricked.
Thanks to user ShotSkydiver we have a Hummingbird build! I will post install details later once I get this up on my device.
