Hi belfastraven,

Thanks!

I installed the SD as a portable device (the first option).

I was coming from the CM12.1.1, I did almost the same as you other than using the nano gapp. After seeing you are using on the File Manager, I now use the Root access for the Fx manager and now it copies.

How do you enable the root to the Fille Manager that comes with it.

TIA.
[Nook HD, HD+ Android Development] belfastraven:
For a while [MENTION=4473900]amaces[/MENTION] was not building the roms with a built in root. This is the first time in a while that the root option has showed up in "developer options" on the marshmallow or cm13 roms. I am not sure whether it works or not--when it was working you sometimes had to set it to "none", then back to "apps" or "apps and adb". One wy to try would be to uninstall supersu and try to use the built in root, but that seems like too much trouble right now, since superSU is working very well:)

I am very happy with the recent aosp build with the newest kernel. Only an occasional lag opening something but I learned to be patient after touching a link. I am going to stick with it. It's much easier to update going forward than going back and forth between older versions and this one. I do miss some of the CM stuff and hope that can work out, but for now, this build works just fine.

Deep sleep?

My 12/13 build (and 12/11 as well) doesn't enter deep sleep and rests at 800 MHz.

Anybody notice this on the amaces's builds?
[Nook HD, HD+ Android Development] captainw1990:
Thank you that worked perfectly.

I tried to install aosp_hummingbird-ota-NDE63P.161106.zip on my Nook HD, but I got error 7. I did flash TWRP 3.0.2-0 from the TWRP devices page. Any ideas? I did a factory reset before I tried to flash the ROM.
[Nook HD, HD+ Android Development] Nevermindthelabel:
You try the one from the experimental folder?
[Nook HD, HD+ Android Development] vinceweis:
^ like he said. You need the TWRP version from experimental with the 3.4 in the name.
[Nook HD, HD+ Android Development] sega dude:
I flashed the recovery from the experimental folder and the ROM flashed just fine. I thought I should mention that the screen in the recovery was upside down. I had to turn the device so that the n button was on top instead of on bottom. The android boot animation was also upside down in the same way. Once it booted up into the setup wizard, I was able to rotate the screen to the correct orientation.
[Nook HD, HD+ Android Development] ipdev:
I've been watching the thread for comments, not sure if it's related but, my test ovation touch screen stopped responding. cm 1030 and twrp -N were the last running. (Rotation didn't work at the time.)

Even a flash back to nook os (cwm backup) didn't fix it. May just have been it's time.

(R.I.P. my good friend.. I wish fastboot worked on these.)

(I have flashed this device so many times in the last six months, you could call it a strobe light.) I've tried a few things and just realized this afternoon I never took one of these apart. (Where the hell is my T4 screwdriver? )

So before I buy a new screen / digitizer, and hopefully bring my HD9+ back from the dead, anyone have an idea to try?
[Nook HD, HD+ Android Development] ieatabiscuit:
Maybe, just maybe, if you flash back to full stock, and do the factory reset from the stock recovery (like when dealing with the battery issue I've beaten to death in the past) it can help? I had a problem with mine acting like the power button was held down indefinitely. In the end, it may be a hardware issue, seems they have some weird firmware that gets botched that nobody knows about? I have all the parts for a good working ovation, but the thing acts like you are holding the power button down. Tghe older a nook gets, the more curious it acts. I love my ovation, but I really wish is didn't act like my kids at times.
[Nook HD, HD+ Android Development] ipdev:
Ha. :laugh: I agree and thank you. You reminded me of something I didn't try yet.

As for factory reset I did. I'm not sure if it was in this thread (or even xda for that matter.) but all I get is the option to factory reset from the boot screen. (Press the home key "n" to factory reset.) Since power, volume and "n" keys are all I have to work with. I thought ovation had an actual recovery menu.

As for what you reminded of, I have not used in a long time, I have an afn cm sdcard image somewhere in my backup archive. (It also contains an old version of nook os..) ;)

I'll try to find that, if I get touch running from sdcard then there may still be hope.
[Nook HD, HD+ Android Development] acr123:
Could someone explain exactly what buttons to press , etc how to do this when in TWRP . I see the mount option but can not figure what to do to see a list of the apks to delete.

thanks,

Al
[Nook HD, HD+ Android Development] belfastraven:
When system is mounted, you can go into advanced options/file manager and look at /system/app , for example, and what you want to delete. Really, if you are not familiar with doing this, you would be much safer using a .gapps-config file. It's just a text file which can list apps you want to remove. You can leave it in the directory from which you usually install gapps, and it will get automatically used every time you install a new gapps. You won't t have to do any messing with the system.

See:

It's very possible that one of the ribbon cables has come loose--heat, dirt, moisture whatever. It is not a big deal to take the nook apart. You need a little piece of plastic to pry off the "bumper" around the screen on the front of the device and then your screwdriver. I assume you have already tried very thoroughly cleaning the screen, including underneath the edgeeof the screen surround. . Is it possible that rotation got turned off in the display settings? Rotation is controlled by the accelerimeter sensor, as opposed to the touch panel.. FWIW

As I near my 10th startup trying to flash the experimental TWRP 3.0.2.0, with my brand new SanDisk Class 4 16GB. I have a stock Nook HD+ 32GB. I have used the Win32 Disk Imager (Run as Administrator) to write the image to the card. It needs asking if some error is not being made.

Power cord in/out (for startup only)?

Screen rotated to a particular position?

Should any buttons be held during startup?

Should the Nook first be factory reset?

Does the card need to be re-written if the root install doesn't succeed (it boots into the stock Nook login screen)?

Should the TWRP screen appear before or after the original black-screen Nook stock logos? Before/After the white Nook stock %s?

Any other suggestions? Thanks in advance.
[Nook HD, HD+ Android Development] ajislav:
I think you are much more likely to succeed if you use the older tried CWM than the experimental..

I.e. stock -> CWM -> TWRP
[Nook HD, HD+ Android Development] belfastraven:
Could you please clarify exactly how you have made your bootable sd card. I understand that you formatted it in windows (not clear if you have to mark it bootable--I've been doing this in linux lately), but it's not clear to me what you wrote on it. The SDcard need several files on it to make it boot the nook, they a re available in a few places here. You should have these files on the card before you can copy the roms or internal recovery images onto it.

When you boot from the sdcard, you should insert the sdcard into the nook while it is off. Then just turn it on. You may have to try a few times. When the card boots from recovery, if you use amaces version of the software or mine, you will get a message saying hold the "nook" key to get amenu. You don't need to do that, since the default will be a 3.0.x TWRP recovery

Can you confirm for me that you have made the sdcard? I can help you find the files if you have not.
[Nook HD, HD+ Android Development] mikeataol:
Hi , You have to go to mounts first and mount system.... then you'll see the apps, priv-apps and all other system folders
[Nook HD, HD+ Android Development] acr123:
When I go to mount in TWRP I can select system as partition to mount. However there is no slider to swipe to do this. The 3 choices that I can tap on are: mount usb storage, select storage or disable mtp.

Is there something I am not doing??

Just installed the newest CM rom OP's experimental folder on Nook HD+. How long should initial boot take? I'm at about 10 minutes now. Is something wrong or should I just wait some more?

Edit: frustrating - tried the AOSP as well, same. Just boots forever. If I don't flash the Pico Gapps (it gives no errors when flashing when I do flash it), then it will boot, but I have no wifi. Not sure what I'm doing wrong.

Coming from CM11 M12 build.

(from the experimental on box)

was written to an SD card via Win32 Imager. I have tried 3.0.1.0 and 2.8.7.5 with no results. I had previously formatted FAT32 and marked active, I do not believe there is a difference if an imager is used as the image should have the correct attributes. Other files were not added, my understanding was the image is all that is needed to boot. It would appear I am mistaken. What is needed beyond the CM and GApps ZIPs? I did ask this question and didn't receive a response a while ago, apologies for the confusion.

Using:

and

ARM->7.1->Pico from OpenGApps.org (currently v. 11/11/16).

Not to throw another curve ball, something is not right with the size with even the Pico GApps if I am keeping up? Shelve this if the above is too far off of what should have been done. T. I. A.
[Nook HD, HD+ Android Development] belfastraven:
Ok, I see what the problem is. I apologize if I am being to "simple" here, but want to make sure you understand.

On your PC, you can run windows from an internal drive, but you can also normally run windows from a USB drive IF you set up the drive properly. It's the same with the nook. What you have done is just copy the files that you would use to install to INTERNAL storage to your sd card. those are the files that you would use the SDcard version of TWRP to install into internal storage, but you have not yet set up the sd card. It's just as if you copied some files to a USB drive that you wanted to use on your PC, but hadn'tintalled windows on it.

So,

reformat you SDcard in windows. Download this zip (for ovation, right?) Get this zip and unzip it on your pc.

https://www.androidfilehost.com/?fid=24459283995300762

Unzip the zip and write the files to your sdcard, making sure that you write the MLO file first. The order of the rest of the files doesn't matter. Then you can copy the files that you want to install to the card, too. the (rom and img files you have).

From the nook being off, insert he SDcard and turn it on. As I said, you may have to try more than once, but your 16G Sandisk type 4 card is really the best card for "booting" from an sd card. The nook doesn't have a problem just "reading" from or "writing" to, most other cards, it's the booting that it is fussy about :)

Before we go any further, let me know that that works. OK?

---------- Post added at 02:43 PM ---------- Previous post was at 02:39 PM ----------

It does take a while to boot. I, too, have found that I couldn't boot if I installed gapps, and that I dfidn't have WiFi after boot. However, If you install the rom, and reboot after installation is finished you will have WiFi,, and it is then possible to install gapps.. You may then have to reboot again to get WiFi. Once you have Wifi and are not installing a rom and gapps WiFi does stay the way you have set it. It seems that when installing roms or gapps, somehow the mac address does not get picked up properly.
[Nook HD, HD+ Android Development] mmnspeed:
I installed gapps before first boot and it worked.It took a really long to e to boot though.So long that I felt I should flash once again.I used pico gapps.The latest ones,don't remember exact date of release.WiFi is also working fine.
[Nook HD, HD+ Android Development] twisteroid:
Flashed TWRP 3.0.2.0, CM14 and OpenGAPPs pico on my HD+. Glad to see shutdown work on first try! VPN service still doesn't seem to work, though.
[Nook HD, HD+ Android Development] mmnspeed:
I had a question.Does usb OTG work on these builds of nook HD+.I did see a video on YouTube perhaps some years back.Didn't give it a try.I could get a female-female USB adapter and try it.

Hangs booting any twrp version

Ovation - has been on pretty much all of amaces cm12+ builds over time

Had the hang on reboot others have mentioned with the 11/6 Nougat build. Followed the instructions from belfastraven (thanks much!) to create a bootable recovery. It boots fine and I can start cwm w/out trouble. I can flash any of the twrp versions but if I boot into twrp either locally or on the recovery sd it hangs on the twrp splash screen. That screen seems to reset every 30 seconds or so.

In cwm If I select "clear data/reset" it returns an error (?because data is f2fs?).

Had same results with my old cwm recovery sd from when I originally rooted it back in cm11?

Not sure what my next steps should be. Should I flash one of the real old romsw/cwm?

Twrp - hangs on splash screen (2.8.7.5 - 3.0.2)

Cwm - runs but gives error when trying to flash more recent roms and/or reset device.

Any ideas appreciated!
[Nook HD, HD+ Android Development] belfastraven:
Yes, USB_OTG using verygreen's app will work on the N/cm14 roms IF they are running the 3.0 kernel. The cm_hummingbird rom from 11/9 is running the 3.0 kernel and USB_OTG works fine, using that app .(the USB host switcher app--its built into the rom right now).

I am trying to get it working on the 3.4 kernel: the USB drivers are quite different and I haven't yet been successful. We have to "force" USB host on, since our weird connector doesn't do it for us. :)
[Nook HD, HD+ Android Development] Tight Git:
I had the same issue and flashed CM11, once that was installed reflashed TWRP then reinstalled nougat and everything is working fine again.
[Nook HD, HD+ Android Development] lorddunlow:
That worked. Who would have thought you had to reboot in between each step? Actually had to reboot twice after flashing Gapps Pico. So weird.

I have it up and running.

Offtopic, but does anyone know why the Vudu app still says my device doesn't support HDX? The app/website just list Lollipop or higher as the only requirement. Oh well. Nougat is running great so far.
[Nook HD, HD+ Android Development] corhsin:
Success, first attempt. I now have a 16 and a 32 HD+ I am trying to get this right with. Where to go from here.

On a side note, I am technically minded when it comes to Windows machines. I understand the concept of MBR/EFI, I just didn't see other options in the experimental or ovation folder to lead in believing something was missing and it is a bit difficult to understand why the reco file is in the obsolete folder if needed. When I asked with no responses, I went with what I felt best. Granted, the reco file is based on 3.0.0.0 which is outdated. Apologies again for making this more difficult than it should be, the school of thought is it is always best just seeking the cleanest start and the most reliable cutting-edge experience, to save from exactly this sort of thing coupled with having to track down some difficult bug because of some leftover file from eight dirty installs ago. The assistance is appreciated.
[Nook HD, HD+ Android Development] prsa01:
Thanks, how far did you go with cm11 and which one did you use? I flashed the most recent cm11 nightly and tried to immediately go into twrp. Same result. Then booted into cm11 but it came up with an error about encryption.

Now when I attempt to boot into either cm11 or the recovery sd it goes immediately into twrp, ignoring the hold "n" for menu. Not having much time to test right now. Will setup a regular cwm recovery sd w/cm11 on it and go from there.

Thanks again, it seems to be getting me closer
[Nook HD, HD+ Android Development] belfastraven:
Just a question--are you running and encrypted device? I never had the problems with TWRP that you have seen, but I'm wondering whether either encryption or (for want of a better technical explanation :) ) something "weird" has happened to your data partition. If you have good backups, I would try making sure you have the rom and TWRP you want to flash on your dc card and FORMATTING data, if you can through the cwm recovery. (It doesn't matter if it will only format to ext4, you can reformat it later to f2fs. )
[Nook HD, HD+ Android Development] prsa01:
No, I have never set it up as encrypted.

If/when I am able to get back into cwm I'll try to format data.

Thanks for all your help. Both you and amaces are helping keep this old tech alive. If we could just get another gig of mem into it somehow it would still be a great tab
[Nook HD, HD+ Android Development] belfastraven:
Ok, great. I know that it is often difficult to wade through/search hundreds and sometimes thousands of posts in these forums. If you read the first post, you will see that a while back someone wrote a very detailed description for how to install the 12.1 roms, and also that amaces explained that he was building for himself, but trying to help those who wanted to use these roms. People really do try to help one another here, but with all of the differences in backgrounds, languages, computer knowledge, erc. It's amazing that we can communicate at all. :) ANd of course, we are all "volunteers"

If you care about being able to restore the contents of you nook to its present state if things don't work out I would do a full backup: Boot with the sdcard to TWRP 3, and go to Backup, then backup at least system and data to the SDcard. That way, you can totally wipe the internal storage if it becomes necessary.

Then, to start out with, using that TWRP 3, I would flash the recovery img file which you have chosen to the internal recovery partition. (you find these options under the INSTALL menu) I would then copy the rom zip file to interal storage. Then, power off the nook. Remove the sdcard and boot to the intenral recovery (using the power and nook buttons. ) The internal TWRP should come up. You can use it to do a factory reset from the WIPE menu. Then you can go back to INSTALL and INSTALL the rom that you have written to your personal internal storage (which does not get wiped when you do a factory reset in TWRP). If you get compaints about system during the installation, you may need to wipe system and try again. Then, reboot the system into system. You should be up on the new rom. That first boot may take quite a while. Let me know how it goes...
[Nook HD, HD+ Android Development] TRS_80:
I've read through most of the Nougat update comments and have only seen one post about the 3.0.2.0 3.4M TWRP install turning the screen upside down ( -180degrees) as default. I've tried 3-4 times ,full wipe / reinstall.... same thing. Even went as far to wipe / format / rescue sdcard. When I go to settings>display>rotation settings and check 180 it will zero to the "n" and is useable. After every reboot nook logo/ cyanoboot universalboot loader are zeroed, but droid head boot is upsidedown and everything thereafter that sets back to system default -180 , i.e lockscreen, SU# app screen, TWRP itself. I flash any earlier TWRP....back to normal. Is there a file I can edit?

Also, having root problems. I thought I only had to install SU# from googleplay as this ROM flash retained ( had built in) root. Binaries won't update trying either normal or TWRP option. I've since flashed several versions in TWRP during several wipe flash tests. Still can't get proper root even though root checkers are saying I have root. Now I'm reading Nougat can be finicky with root. Anyone else having problems? What am I missing?

Other then that...wifi seems good, like the new tweaks to android...seems smooth. Haven't had a chance to use BT or observe long battery life.

TL: DR TWRP 3.0.2.0 3.4M fix for Nougat is defaulting my screen to -180. Root problems for me

[MENTION=5672278]belfastraven[/MENTION] Thanks for all of the help, I have the two packages installed. Two errors during installing

FWIW. HD+ Start to finish:

Format SD Card FAT32 and Active. Better card is <=16GB and <=Class 4.

Unzip the 'reco' file to an sd card, MLO FILE MUST BE WRIITEN FIRST.

Copy the ovation build and ARM 7.1 Pico GApps.

Boot the card. Backup then Wipe the device.

Format data and cache F2FS?

Install->IMG TWRP 3.0.2.0 to recovery partition.

Reboot

Install build CM Ovation 110916.

Reboot and boot. It takes a while.

Reboot.

Get back into recovery. In a perfect world, shut down then hold Nook while booting and select recovery. Everywhere else, if you don't get options with Nook held. break Nook on desk corner or enable developer options.

Protip: In Settings->About Tablet, Press Build Date 7 times to enable Developer Options. You can enable a shutdown option for Boot to Recovery.

Install GApps 110716.

Reboot and boot. It takes a while.

Have no wifi. Search forum for wifi and read dozens of posts about not waiting long enough, not rebooting, soft rebooting or etc., none of which result in wifi.

Try combinations of location setting, safe mode, bluetooth, wiping network information, wiping, resetting, installing and rebooting, different file systems while reciting "it is an experimental, be patient, someone must have figured this thing out and the answer is close."

Tears, then XDA.
[Nook HD, HD+ Android Development] rtarv321:
You need to setup WiFi after you install the build. In other words, after you reboot from installing build, go through the setup until you have completed the process. You should have WiFi. Also set the developer option (advanced boot menu & root). Reboot to recovery & install gapps. The directions are listed a few posts back. Good luck
[Nook HD, HD+ Android Development] corhsin:
I was just altering the post. I have attempted that, every boot into CM the MAC is 02 and it searches indefinitely (being minutes or hours). Finishing setup, the wifi is slashed (disabled) and when entering wifi settings it is 'turning wi-fi on,' or just no information with the bar moving, indefinitely if the nob is off, moved to on, or frozen off.. I have several other devices using the router and power-cycled it to be sure. Can't get the HD+ to see the router it was using with vanilla. Nonetheless thank you for the suggestions.

Edit: I might have missed something, where is rooting? I searched root and didn't see anything that doesn't require a wifi connection.

Edit 2: NM found in 1155: enable root for apps and adb

you might flip it on and off once and then go back and flip it again, that's a common problem in CM....

It was already on. Toggled it twice to be sure, no luck and after looking over the last 30 pages I am giving it up until someone can figure something out.
[Nook HD, HD+ Android Development] rtarv321:
Are you sure that you are setting up WiFi BEFORE you install the gapps pkg. I experienced the same issue as you with WiFi when I installed nougat using the same instructions that I have used with previous versions. I remember in the past the instructions were to always install the build & gapps in recovery together before rebooting. I hope this helps. I am a noob, & probably not explaining things as good as the experts. There are a great group of guys here that have worked very hard to provide builds & instructions for us. I could never thank them enough!
