[Nook HD, HD+ Android Development] verygreen:
By popular demand, I am bringing to you CM10.1 that you can install into Nook's internal ROM.

Note, this version totally overwrites your ROM, so back up everything important before proceeding. This is not a dual-boot solution as before, you do loose B&N ROM for good after installing this.

This is work in progress, yadda yadda.

Simplified instructions if instructions below don't work for you or you cannot follow them.

Get emmc-cwm-early2.1.img.gz, gunzip and write it to an sdcard of at least 1G in size (all content on that card will be lost).

Download CWM recovery (text) or TWRP recovery (gui) zip if you want internal recovery to be replaced with CM one (if you don't know what is it about, then you need ONE of these).

Also download latest binary zip from CM nightlies: http://download.cyanogenmod.com/?device=ovation

Add all these files + whatever other packages you might need right away on to the sdcard.

Boot from that sdcard, and install recovery (if desired) and the cm10.1 binary and whatever else you put there.

Erase /data (During initial install only. this is important to avoid crashes on bootup! Naturally, make sure you have copies of whatever important info from there).

unmount /sdcard and remove the card from the Nook. You might need to use this sdcard for your recovery needs in the future should EMMC content become badly damaged, so probably a good idea to have a copy of it somewhere.

Congrats, now on reboot you'll get into cm10.1 on your Nook HD+.

When you need to get into recovery, you can either do "reboot to recovery" in reboot menu (need to enable that in settings) or reboot the nook, and when you see original nook boot logo, press and hold power + home buttons for about 4 seconds.

If you plan to use USB Host feature, you will need a gender changer, as B&N decided not to release a special cable so far. The control to enable USBHost is in quick settings panel (slide down in the top right corner of the screen to bring it up). (QS controls are not available in CM nightly builds so you'll need to install the switcher app for now if you need it).

Known problems:

- Nook app reports incompatible in market (workaround1: just sideload it ; workaround2: change ro.product.device to nookhdplus in build.prop) - This is because they specifically blacklist Nooks! Note that workaround #2 will actually kill your sound, so revert back when you are done.

- Certain sdcards still remain unstable.

- Google Earth crashes when pressing "my location" button (but works fine otherwise).

Useful apps:

Overall loudness and volume control app: NookHDVolumeAdjuster-1.apk

Touch screen sensitivity control: NookTouchscreenSensitivityAdjuster-4.apk (backup link)

USB host control (not really needed, as you can use Quick Settings panel): USBHostSwitcher.apk
