Please note that this version does not include F2FS support yet. I'm still working on that
Prerequisites: you must have another version of TWRP or CWM already installed on your ovation (Nook HD+) to flash this. If you are still on the stock B&N ROM then you need to get a micro-SD card and follow one of the other guides and experiment with installing CM on the Nook.
Why flash this ? Well, for now if you already have TWRP 126.96.36.199 or 188.8.131.52 from succulent's builds, this one isn't going to provide much more functionality. It does handle exFAT-formatted SD cards, but so does succulent's (that is no accident ) But every so often someone wants to know where to go to get TWRP for ovation on XDA, so here ya go I'm also going to provide some help in building this thing for yourself.
