[NookHD+] CM10.1 native emmc install Now part of CM Nightlies

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:

New snapshot cm-10.1-20130603-UNOFFICIAL-ovation-emmc.zip
Changes:
- Rebased on CM10.1-RC4 source
- returned proximity sensor permisison, to see if it was responsible for some app incompatibility.
- Forced USB Host support.

Forced USB host does not require a special (yet unreleased) B&N OTG cable, but rather is a software hack. You WILL need a gender-changer (female-female USB adapter like this).
To enable usbhost support, plug whatever is it youplan to work with, start USBHostSwitcher and flip the switch into "On", sign under the button should read "enabled". (Sorry, I know this is awfully looking piece of software, but UI is definitely not my trade, neither are android app. If there is somebody who can show me how to integrate this into the status bar or other such central location, that would be excellent).

Both self-powered and external powered modes are working. To enable external powered mode, connect the power first, then enable forced USB host mode.

Note about usb flash storage: these would only automount if you plug one directly, or if you plug into first port of usb hub, other ports would not automount (and I have not found a way to automount usb storage in port-independent way).

New binary drop cm-10.1-20130615-UNOFFICIAL-ovation-emmc.zip

Changes:
- Added WiFi Direct
- Apple magic mouse now works.
- BT reverse tethering (i.e. using your cellphone's internet over BT) is now working
- /sdcard now points to primary storage on the Nook, fixing a bunch of broken apps.
- headphones are now louder too.

New snapshot: cm-10.1-20130612-UNOFFICIAL-ovation-emmc.zip
- Fixed HDMI audio out
- Added USB audio out
- Upstream fix for navbar settings crash is in.

Well, here's a small experimental build to see if boosting default clock helps any lag issues.
cm-10.1-20130626-UNOFFICIAL-ovation-emmc.zip

Changes:
- Default io sheduler: deadline (cfq kind of does not make sense for nvram type devices in my view).
- When screen is on, cpu idles at 800Mhz instead of 400MHz, on input it boosts to 1.1Ghz for a short 80ms. (screen off is still at 400MHz)
- added nls_utf8 into default kernel config: for people outside of US that need it (both for vfat and cifs).
- Updated sgx blobs to the latest - I do not see any changes from it (i.e. beach buggy still crashes), but who knows what might be affected.

So points of testing: see if battery drainage with screen on becomes much worse than it was before
battery drainage with screen off should not really change.
graphics should not become any worse.

no io performance degradation (not that I think there should be any, but still).
