[Nook HD, HD+ Android Development] verygreen:
I decided to start a new thread for 10.1 development on Nook HD+.

Starting with 5/30 build there is a new sdcard layout, so you will need to redo your sdcard from scratch if you were running anything different. See at the bottom of the post for historic info on legacy sdcard builds.

Installation instructions:

- Grab cwm early7.1, gunzip and write to your sdcard using dd under Linux/MacOS or WinImage under Windows. Minimum supported size is 2G. Sandisk Class 4 is best recommended, Sandisk U1/Class10 (you can tell them by being red and gray in color) are NOT recommended,

- Download latest CM sdcard build you want to install, currently latest is: cm-10.1-20130904-UNOFFICIAL-ovation-sdcard.zip

- Download other files you might want to flash.

- Place the install files you downloaded onto the Nook (or you can do adb push later in cwm).

- Insert sdcard that you wrote cwm image to into your powered off Nook.

- Turn on the Nook. CWM interface should load.

- In cwm navigate to install zip from sdcard. -> install from internal storage. (use volume buttons to navigate, home button to select, power button to go one menu level up).

- Choose your files to install and install them.

- When done installing, press power button a couple of times to get to the initial menu and then select reboot option.

- Nook should now reboot into CM10.1 that you can enjoy.

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).

Known issues:

- Nook app reports incompatible in market (workaround1: just sideload it ; workaround2: change ro.product.device to nookhdplus in build.prop) - this is because B&N blacklists ovation platform for the app. Revert back once done, as otherwise you'll lose sound.

- Certain sdcards still remain unstable.

- In Android File Transfer "Internal memory" refers to sdcard and "sdcard" refers to Internal nook storage. This is not a bug and is intentional.

- (original binary was lost due to operator error, so now this binary points to 5/31 release)

Legacy sdcard build info:

Anyway, installation instructions are basically the same as in CM10 thread, just need to use different installation binary.

You might want to use cwm early4 while you are at it too.

Installation on top of CM10 is not recommended.

Please report on whatever problems you happen to meet that I do not already know about.

Sound and video seem to be working.

Binary snapshot from 05/05

- DRM probably does not work.

- internal storage is presented in a strange way in mtp, reason is yet unknown.

- BT Audio does not work

Binary snapshot from 04/24:

- same as 4/22 with "phone mode" disabled.

Binary snapshot from 04/22:

- bt does not work

- probably many other problems that I did not get to see yet?

Binary snapshot from 01/07:

- Bluetooth does not work

- Mic input is very faint

- sleep/battery life is not great, but the system is doing memsleep, it's just seem to be waking out pretty frequently for things like wifi (like every couple minutes, overall I lost ~14% battery in 8 hours on battery overnight on the first test, so definitely nothing to brag about.

- Old familiar notification bar at the bottom does not really work either, so it's a phone-looking top notification bar for now (seems to be upstream problem so far).

- Initial boot animation is distorted - just ignore it.

- Sometimes (usually after update in cwm) boot fails due to a crash in hwc, manifests itself as dimmed bootloader splash or garbage on the screen - just reboot and it'll come back.
