I'm already hip-deep in the process, so this thread is a bit late to do me any good ;) However, one thing I found along the way over in leap's CWM tools thread did make this process faster and easier: you don't have to "burn" a CWM card for the HD/HD+. Apparently the new Nooks' hardware is less picky than older models about what it will boot:

I just extracted the files from verygreen's CWM image. It's a lot faster than burning an image, and especially saved me time because I used leap's CWM to root so I could make a Titanium Backup of stock and then swapped in the files from verygreen's CWM for the CM10.1 install. Maybe verygreen's would have worked for both, but it was no trouble swapping out the files.
[Nook HD, HD+ General] leapinlar:
I don't understand what you want. Do you want CM10.1 on internal memory or do you want CM10.1 on SD? You already now have CM10.1 on internal memory.

If you have a bootable SD in the slot, it should always boot to the SD.

So please tell me what you want.

Got it to write to the SD successfully so thank you for getting me that far. Problem now is that the 32GB nook won't boot from the SD. Maybe some things just aren't meant to be.
[Nook HD, HD+ General] MHRX:
EDIT: Problem solved! Tried the same method again and third time was the charm. I must have had a corrupt download since my wifi was being spotty.
[Nook HD, HD+ General] PiCASSiMO:
I do want to point out that it doesn't always boot from the SD card. In fact, I couldn't get it started with a new 8GB Sandisk Class 4 that I've created using emmc-cwm-early2.1.img.gz. Holding down the power button for a few seconds or longer just gave me a blank screen. As if the battery was dead. Connecting to the wall charger and repeating the process did not help either. It's as if the option to boot from the SD card doesn't exist anymore.

Going back to my original question:

Can I install a newer/cleaner bootloader/recovery? If so, how do I do that? Remembering that I'm still a big noob for this Nook HD+ rooting, I'm assuming that the Cyogenmod bootloader (spinning circle on boot-up) is associated with the same CWM-based Recovery v6.0.2.3 or HD+ SD Hybrid?

And a new question:

I'm looking closer at my About Tablet settings and I'm finding that something is wrong. I see a 20130512 date of my CM mod, which I clearly remember flashing this afternoon cm-10.1-20130706-UNOFFICIAL-ovation-emmc.zip. Is this the old CM10.1 that I've flashed and never erased each time I thought I did the proper deletion and then flashing of the new ROM? See attached screenshot

Thank you.
[Nook HD, HD+ General] leapinlar:
I will try to take this one at a time.

That failure to boot to an SD on the HD+ is a well known problem. It happens with some of the newer devices. I cannot tell you much about it other than it seems to be dependent on the specific device and specific SD's and how the SD is prepared. You can read a lot about it in many threads.

That second issue about the spinning logo. It is the boot animation for CM10.1 itself, not part of the recovery or bootloader. So every version of CM10.1 is going to have that spinning logo whether installed on sd or hybrid or emmc. So I am still not sure what you want with this issue. Are you wanting a new recovery on emmc?

And the last issue about the version dates. Do you have your SD plugged in when booting to get this version date in the screen shot? It may be that the SD is booting to your old hybrid install.

And how are you flashing the emmc version? Is it completing successfully?

[Nook HD, HD+ General] PiCASSiMO:
Well, this is interesting. I've attempted to remove that old 16GB hybrid SD card and try to boot it without any card. And suddenly I get a new TWRP recovery showing up on my screen instead of the old CWM HD+ SD Hybrid. So I decided to flash the 07/06 ROM from evergreen along with GAAPS and voila, I'm running the latest and greatest without the SD card.

So from what I could tell is that the new 8GB verygreen SD card I've made yesterday (per his instructions) was somehow pre-loaded onto the internal memory (emmc) as you call it and then it waited until the 16GB hybrid was removed. I guess that in terms of boot priority, it will take the SD card over the emmc.

At the moment, I can't complain. So far it runs pretty decent except the only hick-up I got was the background screw-up that was shown the usual green leaf instead of the background I've chosen. I'll stick with this setup for the time being, reformat the 16GB card for storage purposes on the Nook HD.

I would like to quickly ask 2-questions:

1. If a new ROM update comes along, can I simply flash the update over the current setup without having to delete everything?

2. When backing up in the TWRP recovery, I have multiple options as to what I can back-up. I decided to use the default checked items, excluding the recovery and a few others. If I decided to flash a different ROM, say CarbonROM, is there a way to copy only the applications I've preloaded from the earlier 07/06 evergreen ROM? Or that's not possible and I need to start from scratch each time I try out a new ROM?

Thank you again for being patient with my Nook noobiness.
[Nook HD, HD+ General] pdx1138:
YES, but be aware that once you do an update instead of a format/erase clean install some or all of your apps

might point to an alias when browsing for files from then on.

so if you were to change your notification sound in email (for example) the file browser will look like

it's pointing to: storage/emulated/0 instead of /sdcard/

they are the same thing and just an alias having to do with multi-user aspect of jellybean.

I just got off the phone with "Samsung" apparently lol the person on the phone slipped up when speaking. Anyways, I will be returning mine for a full refund when the shipping label arrives.

Honestly this is kinda silly praying that a magical SD card will magically force the device to boot from SD card. Really wish there was a sure-fire way to reboot from SD card via ADB or something.

Thanks to everyone who offered to help though and congrats to everyone who got it to work
[Nook HD, HD+ General] leapinlar:
There is a way. If you can get ADB working on stock, just insert the SD and give the ADB shell command 'reboot'. It will then do a warm reboot which is sometimes more successful than a cold reboot which is when you try from the power off position.

[Nook HD, HD+ General] :
ADB isn't too hard usually. Had plenty of luck using it before. Maybe I'll write a python script to automate the reboot then when I get home for one last ditch effort.

Hardware acceleration working?

I did a quick search of this thread (and Google) and came up empty, so apologies if this has already been asked. Is hardware acceleration working (both for HD video decode and OpenGL)? I used CM a long time ago on a Nook Color. Initially it didn't support hardware acceleration at all, and when the OpenGL builds started to appear they were flaky. I got rid of that device long ago so it might have all been ironed out eventually. Is hardware acceleration working properly on the HD+ with CM 10.1 (or newer)? That's probably the only thing that's a potential roadblock from me buying one as another toy now that they are stupid cheap.

Help

i am having the same problem, could you please explain in more detail what you did to solve the problem?

many thanks, phil
[Nook HD, HD+ General] merchant2112:
np i think it was because of the way i formatted the sd card after clearing the 4gb partion.

the first time i did it i simply used diskpart and the delete part command on the selected sd card partition.

the 2nd time i deleted it i selected the sd card, then selected the 4gb partition then deleted it then ran a clean disk command. then formatted the sd carf back to 29gb. fat 32. i think the first time i left some partion tabe crap behind because the card came up as sdcard1 in the nook.

i just re flashed cwr back to the nook hd and it now backs up to the sd card. (as /sdcard not /sdcard1

i like cwr better

diskpart is the fdisk of windows commands should look something like this

diskpart enter

list disk

then

select disk (number of the sdcard )

then

List Part

then

delete part (#)

then make sure you still have the sd card selected

select disk (number)

then clean (enter) it will give a prompt /warning

then you can format the card as normal

use diskmanager create a simple volume format.....fat 32 ect....

then the nook should see it as sdcard and not /sdcard1

or that worked for me anyway

cm10.1 is nice but ill give carbon a try see how i like it

anyone got the nook app apk so it can be sideloaded. cant seem to find it anywhere
[Nook HD, HD+ General] bpaulien:
Hmmm. I wonder if that's what's wrong with my CWM (and TWRP) being unable to mount the SDcard.

One question, do you know if you were able to write to the SD card or copy files to it using an Android file manager? I ask because I'm able to see the card and copy to it from within CM10.1 but can't mount it from recovery.

I may try the steps laid out above, and see if that helps my problem as well.
[Nook HD, HD+ General] merchant2112:
ya i was able to do everything to the card outside of the recovery programs. in windows and in cryogenmod. i think the recovery programs are hard coded to look for /sdcard and not /sdcard1 (or what ever the card mounts as on your system.) you may be able to just fully wipe the card re format it and then go right into recovery and it will see it correctly. after i cleaned it i noticed that the card came up as /sdcard and not /sdcard1

i did do one more thing that may have had something to do with it to....but i dont think it did as it flrmated the internal data card....

i had found a article that talked about formatting /data so i did that and re-flashed cry 10.1 emm but i don't think that did anything. i have seen old boot records mess up the way disk partions are detected so i would try simply cleaning the disk first witch clears out all config info on the mbr

[Nook HD, HD+ General] merchant2112:
if you followed the directions to backup before flashing you should be able to restore the original backup, in cwr go to restore and then select the oldest backup. that should have been the one you made before flashing.

if you did not back it up then search the forum for original stock zip files ive seen a few out their simply wipe wipe wipe and then flash the stock zip.

if you flashed the custom recovery file you will need to find an oe recovery file as well. and flash that.

look around the android dev section those files are out their ive seen them look for posts about restoring to default or stock roms.....

How to restore to stock ROM

I have looked everywhere, but I can't find out information as to how to restore the HD+ back to the factory ROM. I need to return it to Amazon because the screen is flickering when it's plugged in and I don't want to get "caught" with the Jelly Bean OS I put on it.

Can someone direct me to to how it's done. I did do the backup of the factory ROM as recommended, but I have no idea how to use these files to restore it. Nothing I've tried so far has worked.

Thanks.
[Nook HD, HD+ General] leapinlar:
What I mean is copy the backup files to internal memory (where you took it from originally, see Q18 in FAQ). Connect the USB cable to your PC and select 'internal sd' and copy them there. Then go to CWM and select 'backup and restore' and select 'restore from internal memory'.

Or alternately, when you tried to copy the backup files to SD from your computer, what folder did you put them in? They should be put in /clockworkmod/backup.

Two issues: first, there is nothing called "internal sd" when you plug it in, so I just put the files on the root of the device. But there's also nothing called "restore from internal memory" on my screen. I tried restore, but that didn't work, I tried advanced restore, too.

These instructions don't work for me.
[Nook HD, HD+ General] leapinlar:
Are you booting to CWM or TWRP? In CWM there should be additional choices, one of which is 'restore from internal sdcard'.

But if you just want to take it back to stock, look in my HD/HD+ CWM thread linked in my signature and look at items 5 and 6. One links the plain stock 2.1.0 zip and another links restore stock recovery. Flash those two with your bootable CWM SD. Then do a factory reset and you will be totally stock.

[Nook HD, HD+ General] leapinlar:
That means your original backup files somehow got messed up in copying between devices. At least one file is corrupted or missing.

Edit: if you just want stock back, see my last post.

Sent from my Nook HD+ running CM10.1 on emmc.
[Nook HD, HD+ General] e.mote:
The backup files (presumably from CWM if you used the guide) should be in the correct folder structure, the top of which is \clockworkmod, ie \clockworkmod should be at the root of the SD card directory. The entire folder structure is \clockworkmod\backup\backup_name\.

Read the FAQ to see where CWM looks for its backup in Nook's internal storage (hint: it's easier to use the SD card).

Assuming that CWM is installed as the boot recovery software, it should see the backup files by default (which is on the SD card). Once you restore the stock backup, it will also restore the stock recovery, replacing CWM.

I'll probably put a restore section into the FAQ some time later.

>MD5 mismatch

CWM backups generate MD5 hash, which is used to check for backup integrity. MD5 mismatch means the backup is corrupted. Check any other copy that you may have.
[Nook HD, HD+ General] dave421:
Ok, seems to be going now. I had the wrong folder structure and didn't realize it until you posted that. Oops.

Sent from my Nook HD+ Running CM 10.1 from emmc
[Nook HD, HD+ General] dave421:
If the files are on your computer, transfer them to your SD card. If your card is blank, you want a folder called clockworkmod. Inside it, you want one called backup. Put your backup folder (mine is called 2013-07-01.14.57.32, yours will be similar but whatever date you did this originally). The file structure on your SD card should be clockworkmod/backup/2013-07-01.14.57.32/ with the files inside that last folder (boot, cache.ext4.tar, recovery, etc.).

Put the SD card in, select Recovery, and you should be good to go. Hope that helps since it seems you're having similar problems to what I was having.

>I looked at the FAQ but I don't see thepath in the \data folder on my HD+ which it says should be there.

Actually you don't need to know where it is. If you had saved the backup to internal storage, then CWM will automatically find the files when you select the 'restore from internal...' option (rather than just 'restore').

If you had saved the backup to SD card (and then probably copied onto your PC), copy the backup files back onto the SD card along with the requisite folder structure mentioned previously. Then, in CWM, select the plain 'restore' option and it will look for the backup on the SD card.

You are right, if you flash the plain stock 2.1.0, you do not have to flash the stock recovery restore zip. Plain stock 2.1.0 will put stock recovery back. It is only if you are restoring a CWM or TWRP stock backup that you need to flash the stock recovery restore zip also.

Hardware acceleration...

Picked up a 32GB HD+ yesterday so I thought I'd answer my own question. Hardware acceleration seems to be working fine. The rare 1.5:1 aspect ratio seems to trip up some games like I feared it would (e.g. Zombie Smash), but the CM install is painless. Stock 4.2.2. on my Nexus 7 still seems a little more fluid in UI transitions, but for $180 this becomes a pretty nice Android tablet considering it has 32GB (+ 64GB microSDXC capability).
