Fantastic write up.

Everything went flawlessly.

I notice that my device is no longer rooted. Is there a relatively quick way to re-root now that I've completed all the steps in your original post?

Thanks for such a well written guide!!
[Nook HD, HD+ General] digixmax:
Root is built into this ROM and can be enabled in Settings->"Developer Options", but because of a current bug you'd need to enable it, then disable it, then re-enable it again.
[Nook HD, HD+ General] bozzchem:
Let's just say that you effin

:highfive:

Problem solved.
[Nook HD, HD+ General] bozzchem:
Sorry, double post........
[Nook HD, HD+ General] bozzchem:
After getting root access as described above in post #9, I installed SuperSU and SuperSU Pro from Play.

Once the binary updated and I rebooted, I was stuck in a bootloop. I had to reflash the entire process to get the HD+ operational again.

Is this normal? Did I miss something? Does SuperSU not work with this ROM?

I see that the ROM has "Privacy Guard" which looks to be a form of superuser. Ti backup isn't happy with the stock SU and would prefer I install SuperSU. I would love to install SuperSU but don't want to reflash from scratch again.

Any tips/help would be greatly appreciated!
[Nook HD, HD+ General] digixmax:
I believe the "Manage root access" menu in Settings->"Developer options" is meant to eliminate the need for root-access-management apps.
[Nook HD, HD+ General] michealm1979:
I don't see that option after flashing aosp_ovation-ota-NOF26W.170226.zip

Do I need to reflash, and let CWM fix for root?
[Nook HD, HD+ General] digixmax:
Did you not see "Manage root access" under Settings->"Developer options", or not see "Developer options" itself?
[Nook HD, HD+ General] michealm1979:
I don't see Manage Root Access.
[Nook HD, HD+ General] digixmax:
Apparently "Manage root access" is only available on LN ROM.

For AOSP ROM it looks like you still need to install SuperSU, see https://xdaforums.com/showpost.php?p=71063379&postcount=1647.
[Nook HD, HD+ General] RoundSparrow:
Thank you for the work on this. Mine is HD Plus.. Only problem I'm having after upgrade is the unit ignores "Power off" and seems to turn itself on after about 30 seconds of black screen and boots back up. Battery is at 100%, and I disconnected the USB cable, nothing is connected. Anyone else seen this?
[Nook HD, HD+ General] digixmax:
I am running lnos_ovation-ota-NOF26W.170226 and have not seen this problem with this build as well as the previous build.

Did you do a "wipe /data & factory reset" before flashing the ROM/GApps zip files?

Also, this thread which has a much larger set of reader might be a better place to post and get help with questions like yours.
[Nook HD, HD+ General] RoundSparrow:
I did it on two systems, one is 16GB the other 32GB. The one that keeps turning back on was one was upgraded from CM11 (32GB), the other was virgin Nook OS . Yes, I did wipe /data and factory reset, formatted cache, etc.
[Nook HD, HD+ General] ntice:
Yes, my HD+ does that also.
[Nook HD, HD+ General] RoundSparrow:
Thanks for conforming it. I have two units, both HD+. One was 16GB and still on stock B&N before I converted it to LN14.1 2 days ago. The other was 32GB model CM11 converted years back, and now converted to LN14.1 - and it's the one that kept powering on. I let it sit for 6 hours and checked on it - and then it got worse - it was completely stuck at the Nook turn on screen. Cold-started it at least a dozen times, failed. I finally was able to get it to boot into SD Card recovery after about 12 tries. (this same 16GB SD Card worked fine in loading the 16GB HD+). I formatted EVERYTHING, including data, and did a fresh install of LN14.1 / gapps / etc. After a few hours,it got stuck on the Nook turn-on screen again. I guess the MMC on this one is just dead. I don't think it's worth wasting more than the 4 hours I put into it this week, time to retire it. The screens on these are really nice, but the flash memory has always been garbage buggy.
[Nook HD, HD+ General] veilicor:
My dad got a new tablet and gave me his old Nook HD yesterday. It's a pretty old device but a surprisingly nice screen! I installed the latest LN ROM from the page in the OP. I'm also having the issue where the device automatically powers on after powering it off. It's not too big of an issue and I have found the ROM to be totally usable despite this. Big thanks to the developer putting these out!
[Nook HD, HD+ General] neoage:
Is there any fix to the auto power on issue, or is this something we have to deal with? Not complaining, just wondering if there's anything anyone out there has done that has helped them with it.
[Nook HD, HD+ General] digixmax:
There have been reports of this issue of the "power off" menu option behaving as a "reboot", but I myself have not encountered it. You should post your question on the Nougat development thread so as to maximize chance of getting answer.
[Nook HD, HD+ General] webman2k:
So, by the time I got to this thread, the versions of the rooms have been updated compared to those listed in the OP.

I found that flashing either Lineage or Aosp versions along with the latest pico gapps resulted in a successful install, but setup wizard crashing each time. I fixed all installed app by itself, set it up, then went back and flashed pico gapps. That worked without issue.

My only other issue was with launcher3 and browser that comes with this build on Aosp. Browser crashed when attempting to download anything, but easily replaced with Chrome. Launcher is missing settings, choosing wallpaper crashes it, and the search bar doesn't do anything (does something else need to be installed to make the search bar work?). I replaced with Nova to fix those issues without a problem.

Other than that, it's definitely less smooth than the aging cm11-12 rooms, but it's nice to have the modern system on here. Impressed that it runs at all. Great job to the devs. Just wanted to share my experience.
[Nook HD, HD+ General] FoxForceFive:
Just thought I'd post here to potentially help anyone struggling the way I was installing this.

I tried to use this because I couldn't install the new TWRP using the existing CWM as per the other thread.

However, I got the process crashes during setup. I tried the clean actions three times using three different SD cards, each time making sure I didn't install the Gapps file, still, it wouldn't let me through the setup.

I then tried to just install the LN14.1 zip file, & again it crashed, this time I spotted that the clock was shown in the top right-hand corner. I pulled down on that corner & it showed me settings icons, including wifi. I went into network settings through that & set up wifi. Pressed back & it took me to setup, however, I could now go through the 'set up from cloud' option, which didn't crash.

From there I simply added google account & selected don't install any existing apps or backups etc.

Setup then completed. As soon as that was done I powered down, popped the sd recovery card back in & installed TWRP recovery, rebooted again, then installed Gapps.

Took sd card out, rebooted again, & voila, a fully working up to date LN14.1 at last.

It could be something very specific to my device/setup, but just in case it's not, figured I'd post here to potentially help others with the same thing. My thanks to Amaces for putting in so much hard work, & to digixmax for doing such great simple & easy to follow instructions. If these instructions could cause further issues for anyone, let me know & I'll delete it.
[Nook HD, HD+ General] ST Dog:
Step 8 in the first post states to setup wifi.

How were you doing it before, when having problems/crashes, if not through settings?
[Nook HD, HD+ General] FoxForceFive:
It wouldn't let me past the set up new device option & I couldn't get into the settings page using that trick at all, just wouldn't respond to swipe or touches anywhere.

It did let me in the install from cloud options but obv without Internet couldn't go any further.
[Nook HD, HD+ General] ST Dog:
The way you got into settings (from the notification bar) is what the first post meant.

It was the same with another ROM I used on one of my devices (I forget now which).

I see the post was edited and the steps renumbered.

This part. At that stage the only way to set up wifi is through the notification bar.
[Nook HD, HD+ General] digixmax:
In the past (up to and include the 01/04 build), the "first-time" (i.e., after a clean flash/install) setup process as a first step would automatically open a WiFi network setup menu. It now appears that with recent builds (post 01/04 build) one now have to manually bring up the WiFi network setup menu using the setting icon on the notification bar.
[Nook HD, HD+ General] bru20:
Did you read my post on page 1? If you are having the same issue as me, selecting the Nook's "Power Off" option doesn't work, the tablet powers back on.

You have to long hold the power button and the tablet will power off and stay off.

root bntv600 LOS14.1

I'm looking at the settings>developer options>root access

There are two options to root

"disabled" and

"ADB Only"

The default status on root in the window says "Apps and Root" when I click one of the options I'm given after clicking on the option to root and the only option is "ADB" does that mean my nook hd+ is rooted? I don't understand the difference
[Nook HD, HD+ General] digixmax:
The developer has changed the Root setup in the most recent builds -- see https://xdaforums.com/showpost.php?p=72059916&postcount=1873 as referenced in my updated OP.
[Nook HD, HD+ General] yaocihuatl:
I actually found your FAQ in a google search just since I'mma noob I had to figure out some terms in the directions. I ended up getting stuck on setup with LNOS14.1 (your unofficial download) had to drag down on the screen when it kept telling me that the setup was being interrupted and then after setting up wifi to allow the cloud to finish the install I lost wifi completely. This all happened after my first and second attempts at root. I ended up downloading the LNOS root file and it worked , got my wifi back after doing wipe/dalvik and going through it all again hahaha but it's all up and running, just some odd disconnects with netflix which is what I use my nook hd+ for the most. So thanks man, I'm learning and your work saved my nook! Can't wait to see what LNOS does with the promised official release too
[Nook HD, HD+ General] Tzul:
Same problem here. I didn't try the restore from cloud option, because I wanted the tablet to stay offline for the moment. Luckily I know a few Android internals that help to get around this issue with the Setup Wizard. The wizard sets some flags, which you can do manually. After the Nook has booted and shows the Setup Wizard, simply connect it to your PC via USB, and start an ADB shell on the PC (luckily, USB debugging appears to be enabled by default, otherwise ADB wouldn't work).

Then, in the ADB shell, enter these commands:

settings put global device_provisioned 1
settings put secure user_setup_complete 1
settings --cm put secure cm_setup_wizard_completed 1

The last one obviously is a CM/LineageOS-specific setting, not sure if it's needed. Anyway, after entering this, the Setup Wizard will think it has run already, and can be bypassed by crashing it or rebooting.

Hope that helps some people.
[Nook HD, HD+ General] ChennaiBoi:
Upgraded from old CM 11 ROM. The old ROM was very sluggish and hence I wasnt even using the tablet for almost an year. Wanted to try Magzter and I thought why not give this ROM a try as the HD+ screen is excellent for reading.

Followed all the steps and voila I have been reading Magzter non stop for the past 3 hours. Have got about 3.5 hours of SOT and currently battery is @ 40%. So SOT seems good. Thank you for giving new life to my 3.5 old year tablet. :) Wifi works fine. Haven't encountered any bug yet.
[Nook HD, HD+ General] michealm1979:
Latest experimental build seems to have an issue with root, root checker as well as several other apps like Lucky Patcher are reporting no root, and only root options showing in developer is Off, And ADB. It says ADB and Apps before you tap it, but after tap only shows what I referred to above. Is there any fix, I tried flashing the root fix from Lineage, but it fails when I try to flash it.
[Nook HD, HD+ General] digixmax:
Did you install addonsu-14.1-arm.zip from amaces' portal https://notredame.app.box.com/s/26a4bygh9vbaw7jjq08xr5evomvaw5ww?

See the note re: enabling root at the end of my OP of this thread.
[Nook HD, HD+ General] michealm1979:
Completely forgot to flash it, had it on my SD but forgot to flash it, I feel like an idiot ... lol:good:

Well I tried flashing it, after I got home from work, and for this:

Same as using the zip from the LN website.
[Nook HD, HD+ General] nux7osx:
Hi,

Seems like I'm having some weird and difficult issues updating my Nook HD+ with either 5/20 Rom builds of both AOSP and LN. Firstly I cannot boot into TWRP 3.0.1.0 recovery, so I have to use CWM's recovery off my SD card. Once in CWM's recovery image, I can format my system, and install all the ZIP files: TWRP, AOSP Rom, OpenGapps. But once I reboot, I cannot boot off the system, I get stuck at the Cyanoboot splash screen. So I'm stuck there.

Also, I cannot install the latest LN Rom, system reboots in the middle of the install.

I did notice that I do see one error when using CWM's recovery, I cannot mount or unmount, or format the \Data folder.... other than that I get no error messages.

Any ideas?
[Nook HD, HD+ General] digixmax:
Did you check to see if root access for apps is enabled and shows up in Settings->Developer Options->Root Access?

I got similar error messages when flashing the add-on zip file but root access for apps works.
[Nook HD, HD+ General] digixmax:
You can't use the older CWM to flash new AOSP7.x/LN14.x ROMs.

To boot into TWRP, hold down the N button while pressing power button to power on the Nook, then release it a second or two after the Cyanoboot Universal Bootloader screen appears.
[Nook HD, HD+ General] edsib1:
Thanks for this. My nook hd+ kept crashing in setup on the screen after ticking the location box - and this workaround works a treat. This rom is great. Android 7 gives this 4year old tablet a real performance boost and coupled with the still good screen equals a very nice tablet for casual use.
[Nook HD, HD+ General] Shepard4:
Never mind it's a exact step by step. Worked perfectly! Thank you for making a easy guide to follow.
[Nook HD, HD+ General] sacto7:
My HD+ also does that even when I had the CWN installed. Think that I found a solution(?) that stops the restarts after the 1st restart. After the 1st restart I just press the power button, the boot menu(?) flashes & shutdowns down.

Will try the other way next time of holding down the button until some time after the boot menu appears.....

Also found that the led light didn't change from amber to green after the HD+ was fully charged.......
[Nook HD, HD+ General] bru20:
Just finished installing on my HD+, about three months after doing it on my HD. Everything seemed to go just fine. Have had the HD+ for so long I lost a bunch of apps, mostly from Amazon's free app of the day era. I can try reinstalling but the apps are so old I'm not sure how many will work. But now I have a tablet that actually will function, the HD+ with the stock ROM was almost unusable at its end.

It powers off the same as my HD. Have to long hold the power button, after the power off prompt comes and goes it shuts off fine.

So thanks again for the great tutorial. I do have a related question that maybe someone can help with. I have one more HD, brand new in box. I might as well install this and have another nice tablet. IIRC when I power it on for the first time it does a bunch of updates, I have to register it with B&N, etc. Any way to just go right to this? If I have the SD card in when I power it up for the first time, can I just go straight to this install?
[Nook HD, HD+ General] digixmax:
Once you reinstall the Amazon app and login, you should be able to find all your old free apps on your "Amazon cloud", with indication if they have new updates.

Yes, the HD should boot straight to your bootable SD card.
[Nook HD, HD+ General] MoltarRocks:
I had this problem the other day...

I'm new to posting in the forum but recently bought a Nook HD+ off eBay and decided to join. The issue you may have is the SD card itself. When I first loaded one up, it didn't work. Then I realized it was old - really old - I think like a class 2 or 4. So, I found a newer one that's a 16GB class 10. That did the trick. Give it a try and see what happens. I've been happily using mine for a few days now.
[Nook HD, HD+ General] digixmax:
To boot into the TWRP recovery you have to press and hold the Home button, then press and hold the Power button until after the CyanoBoot Universal Bootloader screen comes on, then release both buttons.

The old CWM recovery is not compatible with new AOSP/LN ROMs & GApps, you need to use new TWRP to flash them.
[Nook HD, HD+ General] Shepard4:
I have had my nook for a while now. But I am having a very sluggish and lagging tablet. And also sometime the rotation glitches and I have to press all over the screen to stop the screen tear. I know the nook hd+ is a old tablet, but I thought it would of been a little more quicker with Android 7.1.2 14.1-20170609.

Maybe it's my version I'm running.

Is marshmallow more stable and quicker then nougat?

Also if it is, where can I find older version of lineage?

One last question, if I was to downgrade my OS, would it be the same process as the first time I installed lineage following this guide?

Thanks in advance,
[Nook HD, HD+ General] digixmax:
I have the same experience with the current (0706) and most recent builds typically after the Nook just came out of idle/sleep.

Older builds are located at https://notredame.app.box.com/s/26a...e&sortDirection=desc&pageSize=20&pageNumber=0.

You might want to try the older Nougat build 01/04 (https://notredame.app.box.com/s/26a...e&sortDirection=desc&pageSize=20&pageNumber=1).

To downgrade, download the ROM and GApps zip files to your Nook, reboot to the internal TWRP recovery to do a "wipe & factory reset" and then flash the zip files.

To avoid the hassle of reinstalling Apps in potential future downgrades you should do a complete system+data backup of any build you deem good/stable.
[Nook HD, HD+ General] Shepard4:
Thank you for a detail reply. I will try that older version of Nougat then. Just wondering you said to boot to TWRP and wipe and factory reset. But do I use my SD card recovery with TWRP?
[Nook HD, HD+ General] digixmax:
Assuming that you had flashed/installed TWRP recovery onto your Nook (step #6 in my guide in the OP) you can simply reboot into it and use it in place of the SD-card TWRP recovery.
[Nook HD, HD+ General] Shepard4:
I am trying to restore it back to it's factory setting, I want the nook to be like when I first got it. I loaded the bootable sd card and then I did a wipe and then I did restore. After that I removed the sd card and pressed reboot system. Now the Nook is stuck on the Nook logo and it's keeps going there. I pressed the home bottom and it took me to TWRP without having a sd card. I thought I removed all traces of TWRP from the Nook, but I did not. I know I must be doing something wrong.

Please how do I restore the Nook to how it was when I took it from the box?

Update-

Nevermind I read your post in the beginning and read on how to restore.
[Nook HD, HD+ General] fuzzychicken:
Just wondering if I HAVE to use TWRP. I have CWM v6.0.4.6 installed and running CM11.xx (which is a PITA to use).

I have downloaded CM-flashable TWRP, but would love to know if must use it or CWM will work just fine.

If I have to use CM-flashable TWRP, I assume the installation procedure is just routine, select the zip through install option.
[Nook HD, HD+ General] digixmax:
CWM v6.0.4.6 is not compatible with LN14.x (nor CM12/13/14).

Yes.

Since your Nook is running CM11 you might want to consider using the procedure posted at https://xdaforums.com/nook-hd/general/how-to-updating-nook-hd-internal-emmc-t3562818. A benefit of using SD-based installation/upgrade is to be able to backup your current ROM & Apps onto SD for ease in reverting back if need be.

Beware that a few people seemed to have run into issues with installing the most recent LN builds, hence if you run into the same issue you might consider trying the older build dated 01/07.
[Nook HD, HD+ General] fuzzychicken:
Thanks mate, for your quick answer.

I was so impatient that I went ahead and flashed TWRP file that you linked and it worked flawlessly. If that impatience wasn't enough, I went ahead and flashed ROM and Gapps as well. Since my stars were good, that went well too. It was DW's tablet, so showed her and she was happy to see a quick response from the nook.

So all went well. Thanks for your contribution.
[Nook HD, HD+ General] mattyyey:
So good its amost an unbricking guide!

I've just picked my semi-bricked nook (ovation) up after several months.... From what I remember I broke Gapps removing stuff, then flashed the wrong recovery. boot loop o joy lmfao Anyway then I followed this guide (as it uses boot from sd-card with links) to unbrick it. plain simple clear and concise. Thanks alot. :) :victory:
[Nook HD, HD+ General] bru20:
Longshot but I am wondering if anyone who has modded their Nooks with this has installed the Vudu app and been able to log in to their account? Vudu app installs seemingly fine from the Play Store on both my HD and HD+ with 7.1.2 but I can't log in to my account on either. I get "login failed" on both. Vudu can't figure it out.

The Vudu app works fine on my phone which is Android 5.1.1. My login info is correct and I can log in to the Vudu website while on the tablets, just not the Vudu app. I don't use a VPN and I am on my home WiFi so there shouldn't be an IP blocking issue. Very puzzling.
[Nook HD, HD+ General] ST Dog:
I don't think I've tried the app on the LN14 tablet. I will in a bit.
[Nook HD, HD+ General] ST Dog:
Same here with my HD+ and LN14.1.

Tried Vudu login and Walmart login. Both fail, no other error messages.

Someone needs a log to see if any errors are flagged.
[Nook HD, HD+ General] bru20:
Thanks for checking. I'm always relieved when its not just me with an error but based on my conversation with Vudu and my limited knowledge of the situation I'm not very hopeful it gets resolved. What incompatibility could there be with what is a now generic Android tablet running a current version of the OS and the Vudu Android app? Makes no sense to me.
[Nook HD, HD+ General] ST Dog:
My guess is something in Google's SafetyNet that LOS is tripping.
[Nook HD, HD+ General] bru20:
That's a bummer. Vudu's line is the app isn't compatible with the hardware on the HD/HD+, which I don't think is true. Huge Vudu library and can't watch it on my tablets :( (I can watch it through their website with a Flash enabled mobile browser but not what I was hoping for).
[Nook HD, HD+ General] ST Dog:
Pretty sure it has worked fine on my HD on CM11 for quite a while. So I don't think it's the hardware.

It's installed, but I seldom use it. Screen too small ;) Even my laptop has a better screen and better sound.

Weird that the app launches (though I installed from a backup) and the login fails. That's not typical of a hardware issue.
[Nook HD, HD+ General] bru20:
That's my thought, not a hardware issue. My wife was travelling and I wanted her to be able to watch some movies. A tablet screen is small (the HD+ is pretty large as tablets go, no?) but its nice to have the option when mobile.

If I was more proficient I'd install CM11 to see if the Vudu app does work, as I'm sure everything else would be just fine for my needs as compared to LN14.1 Having installed 14.1 successfully on two tablets I don't want to push my luck.
