[Nook HD, HD+ General] DavidA2:
Thanks for the helpful instructions. I understand the whole process much better. However, I am getting even more of an education (about installing Android) than I wanted.

I have completed all the steps except for installing the Google Apps (gapps). I tried the gapps from the location you recommended and got ...

E: Error in /external_sd/tk_gapps-modular-pico-5.1.1-20150920-signed.zip

(Status 6)

Installation aborted.

Since that, I have tried probably 10 different gapps packages (from this download site and others). ALL OF THEM get the exact same error. I have researched "Status 6" errors, and most seem to indicate malformed "updater_script" files. The updater_script file in all of these gapps packages is just a one line "comment" that says "# Dummy file; update-binary is a shell script." Just to be sure though, I did check the that the file was formatted correctly (with only LF at the end of each line) and it is. I also verified that the "update-binary" file was also formatted the same way.

The rest of the install worked correctly, and my Nook HD+ will boot. But, obviously, I don't have any Google apps (including no Google Play so I can't load anything else).

I have tried wiping the device again, and doing the install over. I get the same results.

I have wiped the device again, and tried a different install of CM. I get the same results.

I have not tried a different version of TWRP. Should I?

I am at a loss right now. Any help would be appreciated.

CM12.1 (amaces build) Blues

I have been using amaces cm12.1 builds for some time, the latest being the much lauded 10/18 build that everyone seems to be running. I had success with that build, but noticed that many processes were slower than in cm11.x. But I liked the features of Lollipop and so I stuck with it, bad battery life and all.

Then I tried updating to his newest build, 12/18, and it was a rude awakening. Every process slowed to a crawl, apps crashed right and left, and the HD+ became unusable - throw it through the wall unusable. Big fail for me. (And no, I don't have logs to show what happened - I just want a usable Nook).

So, naturally, I flashed back to 10/18 hoping the Nook would be restored at least to the level I had expected. No go. It was just as bad. And I didn't want to have to do a full wipe/install - I had already gone through that too many times (just getting Titanium Backup to work properly restoring all my files was enough to send me around the bend).

So I returned to KitKat - the latest nightly - and I couldn't be happier. It is slick, it is fast and the battery life is terrific. This is a mature build that is perfect for the hardware in the Nook. Sure, pushing the envelope is interesting, and I supposed exciting for the developer, but for me, the average user who just wants a Nook that works, the bleeding edge is too painful.

I can now see why CM hasn't adopted official cm12.x for the Nook HD/HD+ - it just ain't going to fly, perhaps ever.

And that's my two-cents worth.
[Nook HD, HD+ General] digixmax:
Have you tried Open GApps package at http://opengapps.org/#?

Also which version of TWRP did you use?
[Nook HD, HD+ General] lmacmil:
Based on your experience, I decided not to install CM12.1 and instead flashed CM11 11/22 nightly. So far so good. I may try 12.1 eventually but for now the 11/22 nightly seems like an improvement over CM11 M12, based on what I've done so far.
[Nook HD, HD+ General] Latiosman:
I follow the process and everything was great after that. I was even using internet, youtube, etc... no prob

That was a few days ago. Today I grabbed again my nook hd+, and it didnt turn on. I though it was because of the battery, so I charged it.

After a few hours, I wanted to turn it on, and it is not working.

The only thing you can see is the little light next to the usb cable, it stays green for a few seconds, then orange, then off, and thats all.

After many many tries I got just one screen: the one that notifies you that there is no battery. But it does not show up the nook welcome screen, neither the cyanogenmod screen. nothing.

I already tried to plug it to another socket, another adapter... but nothing.

Am I the only one with this problem?

It is so weird coz it worked really good after doing the whole process thing.

P.S: I cant even access the recovery by pressing both buttons at same time.

I thought that maybe the problem is that it does not charge. but thats awkard, coz before installing everything with the instructions, I charged it 100%. but I dont know now
[Nook HD, HD+ General] dbrons:
No, you're not alone. My hd+ started doing the same. I had installed 12.1 a while back and all seemed a big improvement from cm10. But it would restart when I tried to shut down, so I'd press the button again and hold and it would shut off.

Well, I started to notice it would not start up after sitting for a couple days despite being well charged when shut down. I'd plug it in to the charger and the lights would act funny as you described. But after an hour or so it would start up.

I just bought a new tablet, a Samsung s2 9.7 which is great so I don't really need the hd+ anymore. I decided, just today to go back to stock. I found my old microsd card for cm10 that has my original back up on it and went back to stock. The tablet seems to start, shut down, and charge normally. It does seem slow to me but that's partly due to getting used to my new tablet.

[Nook HD, HD+ General] zspeciman:
It appears that the unofficial CM13 Marshmallow is out there and is stable. Will there be a guide on how to install that as well?
[Nook HD, HD+ General] digixmax:
The process for a device running stock ROM should be basically the same as posted in the OP, you just need to get compatible copy of TWRP recovery (usually in the same developer-hosted folder as the ROM zip file), Open GPApps package, and (optionally) SuperSU.

If your device is currently already running CM10/11/12, you should be able to upgrade without requiring an external SDcard (unless you want to do a nandroid backup of your current ROM and Apps to SD for ease in rollback): just use your CWM/TWRP recovery to flash the new TWRP recovery then reboot into the new recovery to wipe /data and flash the new ROM, GApps, and SuperSU zip files.
[Nook HD, HD+ General] IndyRoadie:
Thank you so much for this Tutorial. I have been putting off doing a perm root and was booting CM10 off an sdcard. After reading this I went for it. It was easy.

However, it seems that CWM and the latest CM12 roms don't get along. I had to boot into TWRP instead, then everything was smooth sailing after that.
[Nook HD, HD+ General] rs899:
OK, I previously successfully got 2 Nook HDs (hummingbird) on CM12.1 using Pete's guide for the clueless (like me).

When I attempted to flash a different virgin hummingbird straight to Marshmallow (using TWRP 2.8.7.5, the latest CM13 , and nano Gapps) I got this:

Mount: failed to mount /dev/block/bootdevice/by-name/system at/system: No such file or directory.

What do I do now?

Also, how do I get SuperSU on afterwards? Where is this file available for download?

Thanks in advance for helping a noob...
[Nook HD, HD+ General] digixmax:
I'd suggest you try the older version TWRP-2.8.7.4.

Flash the UPDATE-SuperSU-v2.46.zip file from https://download.chainfire.eu/696/supersu/
[Nook HD, HD+ General] rs899:
Yes, but before the failed to mount ROM message TWRP 2.8.7.5 supposedly did install correctly. However, I can't seem to boot into it as much as I have tried to (and I have done it on the other 2 nooks). If the new TWRP is there will the older version overwrite it?
[Nook HD, HD+ General] digixmax:
How did you try to boot into it?

Yes.
[Nook HD, HD+ General] rs899:
As advised , I used the older version of TWRP and finally was able to reboot into it (most likely my fault). I installed the latest CM MM file and rebooted. It seemed to work well for the couple of minutes I played with it. The trouble started when I went back into TWRP and flashed open nano Gapps and SuperSu. They flashed OK and then when MM booted I kept getting "unfortunately setup wizard has stopped" or "google play services" or "clock" and I couldn't clear the popups. I figured that it was an issue with the Gapps, so I tried open pico Gapps. Now it just loops between the ugly android bootup head and constantly "updating android apps".

Where do I go now?
[Nook HD, HD+ General] digixmax:
Which version of GApps did you try?

It should be a MM-compatible version -- e.g., ARM-6.0-xxx from http://opengapps.org/.
[Nook HD, HD+ General] rs899:
I used open gapps arm 6.0 pico 20160106 for marshmallow. I see some issues in the mm thread of bootlooping but nothing exactly like this. The tab heats up pretty badly if i let it churn for a half hour while it says it is optimizing apps.
[Nook HD, HD+ General] rs899:
I finally got CM MM to work by clearing cache in TWRP. No issues after a couple of hours. Maybe battery drain is worse (its not supposed to be that way in mm) but as this is a new-to-me HD , it may be hardware.
[Nook HD, HD+ General] Rammr:
Nook not responding at all

I have a Nook HD+, and I'm positive I've followed Pete's directions word-for-word, but I've tried with two different SD cards and nothing seems to work. With one card, the tablet would turn back on but never acknowledge that there was even a card inside of it, and with this second card, the tablet won't even turn on. I've reformatted the second card a few times and nothing seems to be making a difference. I don't think I'm a dumb person, but given how much effort I've put into this, I'm starting to think I have to rethink how I think about myself.

I don't know if there's anything anyone can do, but can anyone help?
[Nook HD, HD+ General] digixmax:
See the notes in last paragraph of http://xdaforums.com/showpost.php?p=51043572&postcount=1 for info/pointers on potential causes for failure in creating bootable SD card.

Also, if you're using a SD card of size >= 32GB, keep the size of the boot partition to <= 16GB.
[Nook HD, HD+ General] Rammr:
Yaaaaassssss!!!!!! This! I had a 32 gig card but reset the partition to 8, and it instantly booted to CWM! I've been working on this since Saturday, ready to self immolate. Thank you wonderful i'net stranger.
[Nook HD, HD+ General] Rammr:
My last question: this is my first time successfully rooting a device, and I don't entirely understand why I might want to upgrade, or alternatively, how to tell if an upgrade is worth getting and if it's compatible with what's in this guide. Any feedback on that front?
[Nook HD, HD+ General] digixmax:
I'd suggest that you browse the XDA Development threads (e.g., http://xdaforums.com/nook-hd/development/unofficial-cm12-1-nook-hd-hd-2015-04-08-t3078260) and Q&A threads to get a sense of any potential feature or performance improvements -- or issues -- a new build or release has, so as to decide whether it's worth upgrading.
[Nook HD, HD+ General] theoneandonlybrooks:
Just started this process last night. I do have a small amount of experience with roms and what not, I ran custom roms on some past phones. Great writeup. The link in the pdf that goes to a Notre Dame box has two CWM roms, neither of which match the document. I used the one that was most recently updated, which turned out to be 13. Also, the second two links to gapps are dead, but that didn't matter because I needed gapps for 6.0. After some googling, I found the download links at opengapps.org, downloaded them for ARM and marshmallow, did the nano package which flashed fine, then I took the option to clear dalvik/cache, but after rebooting I ended up with the same problem as a previous poster, where it said setup had stopped or something like that. After reading his post, went back into TWRP, did the standard wipe option, and now it works great so far. Early impression is that I should've done this a long time ago. Wow, it's like a new tablet. Thanks for the info!

One weird issue I just found thought, when I go to Google Play, there is no Nook app, and I do primarily use this as a reader so that is a problem. Has B&N just not updated their app to marshmallow yet or what? Anybody? Is there any where I can get the app to sideload it? I have it on my Moto X which is on 5.1, but I want it back on the big screen.
[Nook HD, HD+ General] digixmax:
The issue is not Marshmallow specific -- it applies to CM11 as well.

I'd suggest that you try 1Mobile Market in lieu of Google Play.
[Nook HD, HD+ General] theoneandonlybrooks:
Does B&N block it or something?
[Nook HD, HD+ General] theoneandonlybrooks:
Tried 1mobile, got it downloaded, works great. Thanks.
[Nook HD, HD+ General] digixmax:
I have had this same issue with other apps besides the Nook Reader app, so it's hard to tell what/whose policy cause Google Play to deem them incompatible with the a device whereas alternate App stores such as 1MobileMarket do not.
[Nook HD, HD+ General] theoneandonlybrooks:
I did find the 1mobile app to be very annoying, it kept popping up alerts about apps I downloaded from the play store and created notifications I couldn't swipe about apps it thought I wanted. So I uninstalled it, so far Nook was the only app I wanted that I had to use it for.
[Nook HD, HD+ General] digixmax:
1Mobile Market didn't use to be so intrusively "diligent", but nowadays I do the same thing you do: uninstalling it after I get the app I need, until the next time ...
[Nook HD, HD+ General] theoneandonlybrooks:
I was worried it might be like the Amazon app store way back when. IIRC you had to have the store installed for apps from it to work.
[Nook HD, HD+ General] PeteInSequim:
Well, maybe so. I certainly would like to try it, as would most of my local fellow NOOK users.

First I must finish some other projects, then figure out how to do the installation. Might be a while.
[Nook HD, HD+ General] IndyRoadie:
I followed the guide, with the above changes. Then ran a backup of CM12. Then Wiped, and Installed CM13 and the appropriate gapps. Viola.

Works like a charm. Only problem I have is I can't get TiBU to see CM13 as rooted.
[Nook HD, HD+ General] digixmax:
Did you also flash/install SuperSU?
[Nook HD, HD+ General] IndyRoadie:
Yep. First thing I tried. :(
[Nook HD, HD+ General] yaymartinez:
Cm13 worth the upgrade from 12.1?

Is it worth the upgrade? And sorry to sound dumb, but I want to know how to flash CM13 through TWRP? My nook's currently running 12.1. Thank you. I'm not much of a techie so I'm having a hard time understanding jargons used here :(
[Nook HD, HD+ General] PeteInSequim:
Sorry I can't help with this decision; haven't yet tried it myself.

I would expect no problem using one of [MENTION=4473900]amaces[/MENTION] releases, providing you can find a suitable GApps package to go with it. The open-gapps provider has added a hint to the Android 6.0 package about a needed ROM patch. I haven't yet figured out what this actually means.

Please let us know if you try, and how it works out.
[Nook HD, HD+ General] IndyRoadie:
There is a cm13 thread in the Development Forum. I have installed it and it works well. The only complaint I have is Titanium Backup will not recognize root. Not sure if that is a rom or APP issue
[Nook HD, HD+ General] PeteInSequim:
What GApps package did you use? If open-gapps, could you please tell us what is meant by the "ROM patch" hint that it presents?
[Nook HD, HD+ General] IndyRoadie:
I used Open Gapps 6.0 nano. Not sure what ROM patch means. If you check out the CM13 thread, it might be discussed there
[Nook HD, HD+ General] theoneandonlybrooks:
I used CM14 from the Notre Dame filebox link in this tutorial and then gapps from opengapps, no patch, works fine. If you go to their site, just pick ARM, 6.0 for CM14, and then you can pick which package. I think I did micro or nano. I was starting from stock os though, not upgrading from previous CM version.

---------- Post added at 10:44 AM ---------- Previous post was at 10:16 AM ----------

One other question...

So this is my first time running CM. If I try to watch something on Google Play Movies, I get an error saying it failed to fetch certificate. Is this a CM or root issue? I know at least at one point in time Google Pay didn't (maybe still doesn') work with root, and I think Google Play Movies didn't either, but I thought at least the movie app was updated to work with root. My Moto X DE has the bootloader unlocked and su is active and Play Movies works fine with that. I thought it might be my wifi at home, so I switched the phone to wifi and it still worked.

Any have any thoughts?
[Nook HD, HD+ General] theoneandonlybrooks:
Also, YouTube doesn't work. I also tried tethering to my phone and it didn't help. Additionally, I tried to install twrp manager and it stays I don't have root. I tried to install both SuperSU and the old superuser. SuperSU says it can't update binaries, old superuser just crashes. Is there a setting in cyanogenmod I need to change?
[Nook HD, HD+ General] TeamKilo:
Thanks for the shutdown tip, was driving me mad!
[Nook HD, HD+ General] PeteInSequim:
Are you referring to the unwanted restarts after shutdown? This problem is being investigated. No solution yet, but there is hope.
[Nook HD, HD+ General] coursemyhorse:
Thanks for this guide. When I followed this guide a few weeks ago though, the only available package I could see on the links was actually marshmallow and cynaogen 13. I used this instead and have found a few bugs, but I am not sure if these are related to cynaogen 13 generally, or cynaogen 13 with the Nook HD+.

1: Bluetooth does not work. It will not pair with anything and just hang. EDIT: Scrap that. Only seems to not pair with my car stereo. No other device has issues with it though.

2: Sometimes it goes into a mode where if you swipe to unlock, it will unlock but then the screen goes instantly black. Then you are back to trying to unlock it again and the loop continues.

3: Google search bar is not drawn correctly on home screen. Some of it is cut off.

4: When you shutdown, more often than not, the Nook restarts straight away and will not stay powered down.

5: A weird bug, where the screen keeps flickering bright then less bright like something is wrong with the brightness settings and it fluctuates.

Do any of these issues occur for anyone else? Are they not present on 12.1 or 11?
[Nook HD, HD+ General] IndyRoadie:
Are you using the 02/08/2016 build of CM13? I had the same problems you are having on a previous version, but once I updated to the latest version they went away. So far it has been almost flawless for me
[Nook HD, HD+ General] Skrilrex:

Thanks for the great guide!
[Nook HD, HD+ General] TeamKilo:
Hey guys, I'm trying to use the ps4 remote play app on the nook, but I need root to connect the controller. Is there a dummies guide to root this Rom?
[Nook HD, HD+ General] IndyRoadie:
If you have this ROM on your Nook, it is already rooted.

If not, this IS the guide
[Nook HD, HD+ General] digixmax:
Unlike previous CM10 and CM11, CM12.x when freshly installed does not have root enabled by default.

You can root it by using recovery to flash UPDATE-SuperSU-v2.46 (available at https://download.chainfire.eu/696/SuperSU/).
[Nook HD, HD+ General] fvshaggy:
I installed this and now my Wifi doesn't work. Everything was backed up. Is there something that I can do to get wifi running?
[Nook HD, HD+ General] digixmax:
Did you do a "wipe /data & factory reset" before flashing the new CM12 and GApps?
[Nook HD, HD+ General] fvshaggy:
I followed the instructions and did the wipe/data & factory reset. I am guessing that I missed something along the way but I followed the instructions.
[Nook HD, HD+ General] ipdev:
I normally format/system & format/data (Under Mounts and Storage) along with wipe cache & dalvik cache (under advanced.) before I install. I use cwm boot sd to install TWRP only. After install I wipe cache, dalvik & wipe data / factory reset & power off. (No to root.) Swap sd card with my normal one and boot into twrp, continue installing from there.

(Forgot mention, you need cm, gapps & what ever else you want, on the normal sd card.)
[Nook HD, HD+ General] fvshaggy:
Should I go ahead and reinstall again?

Thanks for any help.
[Nook HD, HD+ General] ipdev:
Might as well wipe, and reinstall again if is not right.

When all else fails I restore it back to nook os. (cwm backup like the guide shows you.)

I wipe everything, restore my nook os backup, wipe everything again, then reboot into nook os. Go into settings and factory wipe it from there. (Deregister maybe?) Its been deregistered before so it just wipes all and reboots to Welcome to you nook!

Then you can start fresh with the cwm boot sd card & page 10 of the guide.
[Nook HD, HD+ General] baytee:
Qstn on "twrp can leave your system partition unmodified"

Thanks for the steps Pete. I followed them but adjusted them slightly as I'm installing CM11 latest nightly instead of CM12, since I've read quite a few bad reviews about performance with certain things when running CM12 on nook hd+ I may update down the road to CM12 but am a bit nervous right now. See comments at the end of this article (article about Nook Tablet, but comments talk about HD+ and CM11/12) :

http://www.androidpolice.com/2016/01/15/still-rocking-a-nook-tablet-you-can-now-jazz-it-up-with-a-cyanogenmod-13-nightly/

One thing though, when first booting TWRP (before installing Gapps), I get the message "twrp can leave your system partition unmodified to make it easier for you to take official updates. TWRP will be unable to prevent the stock ROM from replacing TWRP.....etc. with a choice to Allow Modifications or Keep Read Only." What do you advise? Though being able to "easier take official updates" sounds nice, the part about stock ROM replacing TWRP doesn't sound nice. How will updates work anyways? Will my Nook just update as needed either automatically or by prompting me? Or do I need to repeat your whole process to update?
[Nook HD, HD+ General] Borghi:
I just tried installing last night and my wifi was not working either. It kept searching for a wifi location but never found any (yes I have working wifi). I did wipe the device before installing CM. Did you ever get this fixed??
[Nook HD, HD+ General] KnownDominance:
Hey, I am having the same problem with Wi-Fi not working. Does anyone have a fix for this?
[Nook HD, HD+ General] ipdev:
In Startup Wizard, I had to add network. (I have to manually enter network since it's hidden.) If it didn't connect within a few seconds, I added it again and was connected. After that every now and then I would have to turn off WiFi and turn back on. Once in a while I would have to forget network and add new. (I assumed it was a dhcp renew / release error.)

You can try to manually add your WiFi and see if it works.

I have been running cm13 (or asop) builds for the last few months. (Thankfully WiFi hasn't been too much of an issue.)
[Nook HD, HD+ General] woldranger:
First of all, a big thank you to all the guys helping keeping these Nooks up and running!

I'm not new to installing custom ROM's but I've never done any modding on a Nook. I bought the HD= for my Mother a couple of years ago but the stock OS is garbage and it only gets used for watching movies now so I'd like to breathe some new life into it. My main consideration for adding a ROM is stability because, if something goes wrong when I'm not around, my (retired) Mother won't have a clue. So I was wondering, would you guys recommend sticking with CM12.1 or moving up to CM13 as it's going to have more support?
[Nook HD, HD+ General] digixmax:
For stability I'd suggest you consider CM11.
[Nook HD, HD+ General] fvshaggy:
I haven't been able to figure it out yet. I reinstalled but it did nothing again. Good luck to you!
[Nook HD, HD+ General] KnownDominance:
Damn, I also can't figure out how to flash the Gapps package because TWRP won't launch
