Default [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:
 

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

Thanks for this though.

Verygreen, I am interested how this boots without sdcard as before the expliot worked because B&N left dev code to boot a kernel from sd card.

What exploit is used to boot from internal since sdcard isn't used.

Also I don't think cm10 is needed really.

I think its best to put the work into cm10.1 as its the latest platform and try bring that up to the same stage as cm10.

Wow, thank you once again verygreen! Thank you so much for your efforts!

I'm just wondering, does this overwrite the stock ROM, this no dual boot? Also, are there any performance differences?

Regardless, appreciate your efforts once again!

Is the reboot to 99% problem solved ? This is the biggest issue to me.

Same method as Bauwks, B&N forgot to fix it, they fixed some other possible vectors only.
I was holding to this knowledge hoping that it would be useful on next B&N reader, but it does not look like they'll release another omap-based one, so no need to keep suffering anymore.
So here's hope whatever they release next, the debugging code will remain in place

Yes, this does overwrite stock ROM, so no dualboot.
While it's possible to perform some hair-splitting by putting multiple kernels into boot partition, that's quite a bit of hassle + all the /data splitting, so I decided to not go that way, at least yet.

There are performance differences. I did not perform any real studies, but I was shocked at how fast the install phase in cwm works compared to sdcard.

Yes, it is solved by removing the ROM, so nothing is left there that could complain about cards with too many partitions

Default Awesome

I've gotten this loaded up this morning, haven't done a whole lot with it as of yet, but it did boot right up

I have noticed one thing that is not working correctly, specifically the sd card. It's reported as not mounted.

Yes, I was just going to post that. Verygreen forgot to change the vold.fstab file from the sdcard version to emmc version.

Go to /system/etc/ and edit the vold.fstab file to say "/storage/sdcard1 auto" instead of "/storage/sdcard1 5". Just change the 5 to an auto. Then reboot and it should be ok.

It's always the small things that gets forgotten, sigh.
I knew I needed to update that, but did not find it at 4am. Now it's in my tree, so next version will have it fixed.

Also need a better way to write sdcard image, I guess, without uploading a whole gig or so of zeros which will get slow. I tried to put in some shortcuts to minimize the write area, but failed so far. Since everything is in the same partition, changing stuff on the fly is hard.
Perhaps a solution where we only use sdcard as means to do initial bootstrap and write correct recovery and use /data/media as the actual sdcard would be better after all.

Default Follow up question

Could one of you guys explain a method of going back to stock from this? What I mean, is it possible to install Leapinlar's version 2.1 back to the emmc using the recovery used to install this emmc-based CM 10.1? If you suggest that we backup before installing this ROM does that mean that we can use that backup to restore the stock we have on emmc now back to emmc if this were not to work out well?
