Thanks for your response. Sorry for my ignorance. These files will be very helpful, but if my nook is at stock now? I thought I needed the full .rar file to root from stock. I suppose I can root CM 12.1 the use amaces files on that. I thought I was taking a short cut. I guess not.
To root amaces' LNOS ROM, just flash the addonsu-xx.y-arm-zip file at https://notredame.app.box.com/s/26a4bygh9vbaw7jjq08xr5evomvaw5ww.
I can burn the .img file to the SD card using the method you've explained. But can I still return to stock? My main concern is that I want to make sure I have the ability to do so.
While in SD-card recovery, if you make a full back up of your stock ROM (onto the SD-card) before flashing custom ROM/GApps, then you should be able to boot into SD-card and restore stock ROM from this full backup.

Alternatively, you can go back to stock ROM using the leapinlar's stock ROM & recovery files at https://forum.xda-developers.com/showthread.php?t=2062613. (You should check and make sure that the link to his files are still live).

No need to root stock since the Nook HD will boot from an SD card.

Once you boot to recovery on the SD card you can access the whole tablet to back and/or flash.

I never rooted stock on my tablet.

In ran CM11 from the SD card for years before finally installing to emmc and moving to LN14.

If a SD install of LN14 ever existed I'd still be runing from SD.

I was able to root the stock to Android 7. But now I want to make sure I can go back. I now have Android 7 on there. But, I would like to be able to just take the SD card out and there the stock is. I'm just not really following on how it's done I guess. How did you do it? Can it be done with Android 7? It's not my first time doing this, like when I did CM11, I was able to use leapinlar's post to get back. But the SD card removal method would be so much easier, once it was set up. Plus, my husband would feel better if he could keep stock on his HD+, but have the option of a better system. Here's what I did do.

I know I'm way overthinking this, but, I guess it's what I know. Using my un-rooted stock Nook HD:

First I'm using this link file and extracting it, then dragging the MLO (first) to the SD card. Then I copy the other files that were unzipped.

Then I'm dragging Android 7 CM to the SD card still zipped.

Lastly I'm dragging the gapps 7.1-pico file down to the SD card along with any other zips that I might find useful, such as Unknown Sources and also TWRP 2.5 .rar zipped file.

Properly ejected from my laptop, I put the SD card into my powered down Nook HD and fire her up. I backed up and restored the system to the external_sd. Did a factory wipe and reset, then I flashed my zips. Yadda yadda, and I now have Android 7.1.1. Otherwise classic old school procedure, but no stock... :\ Any tips on what I might do to do what you did to get stock to stay?

First, you seem to be under the impression that the 7.1 OS is running from the SD card. That is not correct. The TWRP wipe/flash process removes stock entirely from your Nook's innards and substitutes Android 7.1. You should remove the SD card when the process is complete and put it somewhere safe. If you want to use an SD card to store data, etc., you need an additional one. The card you used to flash 7.1 is just for backing up, restoring, flashing new OS, etc.

If I understand you correctly you want to be able to boot into stock or 7.1 at will (from the SD card?). Such a thing is not possible. You can only have one operating system at a time and it's

internal. If you want stock, you will need to go into TWRP, wipe out your 7.1 and restore the stock backup. If you want to go back to 7.1, you will have to repeat the procedure, wiping out stock and reflashing 7.1 (presumably from a backup). This is no way to live :eek:

Is there some reason you desperately want access to stock? Do you have a bunch of B&N purchased books you want to access? If that's the case, you can just install the Nook app on your 7.1 system, sign in, and all your books will be there. The only other advantage of stock I can think of is a working HDMI port, but if that's the issue you can install a CM 12.1 or CM 13 build that will still preserve that function and will be just as functional as 7.1

So why do you need/want stock so much?

To accomplish what you want requires a ROM build that was compiled to run off an SD card. The most recent version of Android OS for which there were such SD-based builds was v4.4.x (KitKat) dated circa 2013/2014 -- see https://forum.xda-developers.com/showthread.php?t=2583952 or https://iamafanof.wordpress.com/2013/12/20/cm11-0-kitkat-android-4-4-2-for-nook-hd-xx-20dec2013/.

Thanks ST Dog, I knew I had been able to do it once. It was Kitkat. Sorry for the long posts.

I have apps in the Barnes & Nobel App store that I have paid for that I don't want to pay for again in Google, mainly. Still trying to figure out if it's possible to sideload them. So far I haven't been able to find a reliable APK that has them. I was able to do get it all set up so that I can go back to stock reliably. I can't, for the life of me, use TWRP or CWM to go back to stock (via backup or using the plain stock files) when the recovery program is on the internal memory. Doing it from the bootable SD card works like a charm however and I'm pretty satisfied with my comfort with that method. But there's a part of me that is a little OCD as to why it doesn't work on the internal recovery program. Whatev' I guess. As long as there aren't any drawbacks for the internal recovery program not being able to boot it back to stock. Maybe it will help people for me to share how to do it on here now that I've figured it out. Just afraid it might be redundant.

Don't think there's much hope to get from the B&N store to newer ROM.
Unless you can fond a version if the B&M app stone app that works on 3rd party ROMs. I don't recall ever seeing anything like that, not even for CM10.

K'd just bite the bullet and forget/repurchase those apps.

Stick with the N ROM you like.

I think there was an option at option point to run the B&N ROM from an SD card. If you can find the thread/files that night help you.

I'm not sure I understand your question, but it sounds like you want to install Nougat the hard way; by starting from Stock.

I can't help you with this, but please be aware that installing Nougat as provided by @amaces has never been easier. Following are the steps:

1. Download these files for Nook HD+ (Ovation)

sdcard-reco-ovation.img.xz, lnos_ovation-ota-NJH47F.171021.zip, twrp-3.0.1-0-ovation.zip

Or these files for Nook HD (Hummingbird)

sdcard-reco-hummingbird.img.xz, lnos_hummingbird-ota-NJH47F.171021.zip, twrp-3.0.1-0-hummingbird.zip

2. Download the current ARM 7.1 pico file and its MD5 checksum from. Since we're cramming a lot into limited storage, you might want to prepare ato include with your installation.

3. Use the - - - .img.xz file to build a bootable microSD card, using a card at least 1 gB capacity (I prefer 8 gB). This file is a compressed image that when decompressed and written onto the microSD card will make it bootable to TWRP. If you use a Linux desktop computer for this, use the archive manager to do the whole job with one click. If you are Windows-oriented you will have to first decompress it, then install the decompressed image onto the card. Sorry, I've never done this and can't provide instructions.

4. When the bootable microSD card is ready, drag and drop or otherwise copy the Inos, TWRP, and gapps zip files, the gapps MD5 file, and the gapps-config file onto it.

5. Eject the microSD card, mount it in your Nook, and power up. It will boot to TWRP. Follow the usual wipe and install procedure for zip files from the microSD card. The preferred order is Inos ---, TWRP---, and gapps---.

6. Post a reply to this post to let us all know how it worked for you.


Hi,

Sorry, I'm new to this, and would like to ask a few questions, if you don't mind. Forgive me if slip into idiocy at any point. :D

I have a Nook HD+, still with ROM it came with, or "stock" as I believe it's called, and I'm just debating whether to try installing CM12.1, as instructed in the first post of this thread, or jump straight to trying this, as I know CM12.1's getting a little long in the tooth, I think, based on Android 5 (5.1?).

Can I use this technique to go straight from stock to "Nougat", or is there an interim step? Is this just as easy as installing CM12.1, or would you recommend should I stick to the first post if I'm a "N00b"?

You say this will install Nougat on my Nook. Is it the standard version of Nougat, or is it the LineagoOS port/variant? (which, incidentally, I don't have any issue with, and might even prefer)

"Download the current ARM 7.1 pico file" that's the standard ARM version I need, not ARM64, isn't it? (I'm not exactly sure if the Nook has a 32 or 64bit chip in it, to be honest :eek:)

Thanks for any help.

You can go straight to N.
The files mentioned in the post you quoted are for Lineage.
The Nook CPU is 32bit.

Is there anyone still reading this thread? :)

NOOK HD+ Question

: Does the HDMI-out function work in ANY recent builds?

I ask because I remember hearing the HDMI adapter wasn't working in Android7/CM14 but it was working in Android5.1/CM12.1

Did install Android 7, but even slimmed-down gaps-pico
was not able to get flashed.
Now thinking about resizing partitions, is it possible ?

It's possible. I recall steps being mentioned here on XDA in the past.

Look for repit
