I appreciate the offer, but unfortunately I have a Nook HD. I'm using the hummingbird version of that same Lineage build. It seems like it works fine without GAPPS thus far except for this storage issue.

I've tried wiping and reflashing the ROM and it still says I have 0 bytes free in the included files app. Trying to download anything with the included browser just crashes the browser, but I can install apks via an SD card, F droid, etc. just fine.

I can't see any folders when I plug the tablet into my PC either. I can open "Shared Internal Storage" just fine but nothing is there and I can't write to it.

If the ROM has been proven to work well for others, perhaps I made a error while installing? I followed OP'S guide (From a stock install) exactly, so I'm not sure what I could've messed up.
The issue you're facing is most likely an "internal storage" issue. A partition was most likely corrupted at some point during the flashing of something. That's why you can install onto the internal partition, but not from it; remember, TWRP is installed onto the "recovery" partition but if the main partition is already corrupted, all you're doing is going in circles wiping and flashing from something that is already corrupted . This issue hasn't happened to me on my Nook HD+, but it did happen on a rooted Nexus 6 with a Custom ROM, as well as a rooted Note 4 with a Custom ROM I had in the past. Only returning both phones to factory stock; to restore every partition to it's default state, and then installing the Custom ROM again fixed those issues for me. If you don't have the stock Nook HD zip to return the Nook HD to Barnes & Noble's stock OS, I'm sure I can find it somewhere on an old hard drive I have; I did have a Nook HD at some point in my life, but the Nook HD+ was a lot better for reading Manga so I got rid of my 7 inch Nook. If that still doesn't work, maybe you should try expanding the /system partition with REPIT; maybe the Nook HD doesn't work well without Gapps and they're necessary for the functionality of the LineageOS ROM on the HD version, who knows.

If that is the case, why can I install apks and why does my storage correctly show up in settings? Very frustrating stuff.
i just flashed LineageOS to my NookHD and had the same issue with a different apk, im not sure what the cause is other apps install just fine its strange, i will try to find out the issue

If you could upload the original OS zip, I would greatly appreciate it. I kinda jumped into this without making any backups because I didn't have anything valuable on the stock OS.

Is the process for going back to stock the same as flashing the custom ROM? (Wipe everything and then flash the zip?) Would that be all I have to do to correct any corrupted partitions?

On a side note, I did change the partitions by following that Github guide to install GAPPS initially, but changed them back to stock using the same method after I couldn't get GAPPS to work without crashing.

I presume it is possible that this internal storage issue could also be the reason GAPPS won't work.

The process for going back to stock is just like clean flashing a LineageOS or Gapps zip, that's it. This stock zip will not even make the Nook HD work as far as being able to login to your Nook HD's Barnes & Noble account. I saved this zip file before the newest Barnes & Noble zip update was released; that one update fixed the ability for people to login to their Barnes & noble account since this one was outdated, but I don't have that newest one. It will restore your Nook to factory stock nonetheless which is what you want; not because that might be your problem, but it's better to be sure once and for all whether your partitions are corrupted right now or it has something to do with the REPIT /system partition situation. Who knows, maybe the motherboard fried and it has nothing to do with anything.

Thanks! I'll give it a shot when I get home, and then I'll try Lineage again.

Ok, so I was able to successfully flash back to stock and that booted up just fine.

Followed the guide again from the beginning and suffered the same exact issues both with GAPPS and with the inaccessible storage. Going to try the AOSP ROM and see if it has the same issues. :/

EDIT: The included internet browser on the AOSP ROM also crashes whenever I try to download anything. Same behavior. I'm about to chuck this thing out the window.

Using another device copy the .apk's you want to your SD card, insert the SD card in your Nook, open the "Downloads" app, in the hamburger menu select your SD card, now install your .apk's and see if you have any issues.

Try a Marshmallow ROM. I remember those didn't have the Gapps size issue, so if one of those ROMs works with Gapps, then it has to be a /system partition resize issue. There's no way you should be able to go back to stock and re-flash ROMs with a damaged motherboard. Aside from all that, the only other common denominator would be the TWRP image you're installing on the Nook. You could try a different one but that's a stretch. I wish I still had my Nook HD so I could try more things. That tablet is worth saving if only for that 1,440x900 pixel resolution screen; it was ahead of its time. Well, good luck.

Finally got the darn thing working. I had tried "aosp_hummingbird-ota-N2G48H.181223" that I got from another thread, and that one had the same issues as the Lineage build from OP's post for me. I just flashed "aosp_hummingbird-7.1.2-20181227-1604" from this thread and now the storage issue appears to be gone. I haven't tried flashing it with GAPPS yet. I appreciate you guys trying to save my sanity.

I'm glad you got it working. Now you have everything you need; a stock ROM, a custom ROM, and knowledge on how to resize the /system partition. You should be able to get the Nook HD exactly as you want it.

I was running stock and had my HD+ sitting a drawer for a while. I now want to set it up with chrome in my kitchen to pull up recipes. I decided I should start clean so I did a factory reset but now it just boot loops to TWRP. I figure I'll reflash, but the download links for stock and LOS14 don't work anymore. Can anyone connect me?
Here the step you need to follow to get LineageOS back up and running:

• Grab the "lnos_ovation-ota.zip" from post #3,

• Grab Google apps from https://opengapps.org
For the options choose the following
Platform = ARM
Android = 7.1
Variant = whichever one you want (i recommend "pico")


• Download the attached files below,

• move the downloaded files to your microSD card, insert it in your NookHD+ and boot to TWRP,

• now start by doing a "advanced wipe" select everything execpt your SD card,

• Now choose "install" and select: "delete-backup-of-stock-rom-hummingbird-ovation.zip"
(That deletes a backup of your stock ROM, you need that space for Gapps)

• the next to install is:
"lanchon-repit-20170115-factory=32M-system=1G-cache=32M+wipe-data=max-ovation.zip"
(this file resizes some partitions which you need to do in order to be able to get Gapps installed)
(this file may take a long time and CANNOT be interrupted)

now install the ROM (lnos_ovation-ota.zip) & Gapps, reboot and you should be good to go

The storage issue only pop up while installing the GAPPS.

I had managed to flash the lnos 7.1.2 and had observed the following:

a. The tablet [nook hd hummingbird] now have to permanently plug into a power source, otherwise it will shut down.
a1. All apps when launched would be 180 degrees rotated ...

b. I encounter the storage issue while installing the gapps. I had deleted the partition [and my earlier backup, that's a grave mistake] and had failed to extend the partition [error encounter while flashing the zip]

c. If I removed the power, the tablet will shut down unexpectedly and the tablet won't be able to recover. I had to flash the lnos rom again.

d. If I plug a proper shutdown tablet into my Ubuntu desktop, the tablet won't boot, and continuously loop.

e. Now I remove the unable to boot tablet and plug into power source, the tablet will boot to twrp 3.0.1 recovery. The tablet recovers after power to system.

f. As I had deleted the partitions, I am now unable to flash back to 4.4.2, and I am stuck with this 7.1.2.

g. I hate the trouble of having to always plug the tablet to a power source [even if it is 100% charged] and unable to connect to my ubuntu desktop, and without the GAPPS.

h. I am hoping someone to help me to install the TWRP 3.1.1 img and to perform the partition extension again.

i. I hope my observation on having to permanently plug the table to a power source is not a bug in the lnos 7.1.2

Thanks

Any suggestion how i can get back to 4.4.2?

twrp-3.1.1-0-hummingbird.img

How can I flash a img in TWRP or CWM recovery? Both allow only zip flash.
To flash the Twrp .img:

• boot i to Twrp,

•Chose "Install" now in the bottom right corner there is a install image button (as shown in the picture)

•click that now find were you have the .img stored and it should now be appear.

NoFileName_0_1.jpg




a. The tablet [nook hd hummingbird] now have to permanently plug into a power source, otherwise it will shut down.
a1. All apps when launched would be 180 degrees rotated ..
a. Well this isnt good, it might have something to do with you not running Twrp 3.1.1.0, once you get that installed (following the instructions left above) do a advanced wipe again reflash the ROM, let it complete first boot then try to unplug it.

a1. This is because the ROM developer messed up the rotation setting, go to Settings > Display > When device is rotated, or Settings > Accessibility > Auto rotate screen,

Because the rotation settings are messed up some apps will launch at 180 degrees unless you lock rotation while using that app.


b. I encounter the storage issue while installing the gapps. I had deleted the partition [and my earlier backup, that's a grave mistake] and had failed to extend the partition [error encounter while flashing the zip]
If your willing try this:

• Get the partition extending file onto youe SD card,

• boot to twrp,

• do a advanced wipe

• now try to flash the file from your SD card

Also what was the error when changing the partitions?



c. If I removed the power, the tablet will shut down unexpectedly and the tablet won't be able to recover. I had to flash the lnos rom again.

d. If I plug a proper shutdown tablet into my Ubuntu desktop, the tablet won't boot, and continuously loop.

e. Now I remove the unable to boot tablet and plug into power source, the tablet will boot to twrp 3.0.1 recovery. The tablet recovers after power to system.

f. As I had deleted the partitions, I am now unable to flash back to 4.4.2, and I am stuck with this 7.1.2.

i. I hope my observation on having to permanently plug the table to a power source is not a bug in the lnos 7.1.2

Thanks

Any suggestion how i can get back to 4.4.2?
c. you can try flashing Aosp or Cyanogenmod (i suggest Aosp over Cyanogenmod) and seeing if that resolves your issue,

This also you mean you have a bad battery, you can replace them, but bewarned i tryed and my Nook HD wouldnt take the new one, (but others have done it)


d. This is probably a bug of Twrp 3.0.1-0 let me know if this continues after upgrading to 3.1.1.0


f. If you really want to get back to 4.4.2 there might be copy's of the stock ROM or Cyanogenmod here on XDA but i dont have the links, also dont give up quite yet i might be able to work through some of these problems


g & i. This is definitely a unique issue but assume this isnt a hardware issue im sure we can find the soultion,

Managed to flash the TWRP 3.1.1 img, I shall continue the remaining. Thanks.

Just an update on updating the rom on my nook hd hummingbird.

a. I had successfully flashed the TWRP 3.1.1 recovery.
b. From TWRP 3.1.1 recovery, I had done a total wipe [all checked except sdcard]
c. I had flashed lnos rom. Booted up successfully. Whilst the fully charged nook will again shut down when I unplug the power cable.
d. I had again done a total wipe[all checked except sdcard]
e. However I flashed cm rom instead. Again my fully charged nook will still shut down when I unplug the power cable.

I had for once successfully flashed the gapps together with the cm rom [need not perform any partition resize]


However one problem I would like to feedback regarding the cm rom:
1. The file manager [comes with the cm rom] won't install any apk in my sdcard. I can install the apk only when I am using another file manager [i had downloaded the ez file manager from play store]


And thanks Falcon342 for his prompt response to my my query.

I honestly believe this issue with the Nook refusing to stay on unless plugged in is a battery issue, i cant think of anything in the ROM's that could possibly cause this,
(i have the Nook HD Hummingbird and dont have this issue)

Glad you were able to get Gapps up and running, but it is a bit strange considering CM is the biggest ROM out of the three,

i havent messed around with CM to much, but in my brief testing i dont remember having any problems with CM's file manager, im not sure how to fix this issue,

if you would like i can walk you through how to remove it so its not taking up space/resources,

No problem.

No problem.



I had downloaded the gapps from:

And that's 79282kB
However from opengapps [same for arm, 7.1, pico], the file size is 171748kB. That's likely why with this gapps, no partition resize is needed.


Yes please advise how i can remove whatever apps so as to save space and resources.


I had earlier deleted the partition using [delete-backup-of-stock-rom-hummingbird-ovation], and had failed [lanchon-repit-20170115-factory=32M-system=1G-cache=32M+wipe-data=max-hummingbird].



Now that I had the TWRP 7.1.1, I would try the delete and extend partition again. And followed by flashing the lnos and the smaller size GAPPS. Hopefully that would resolve the power or file manager issues that I had observed earlier.

    How to install Aosp 7.1.2, LineageOS 14.1 or Cyanogenmod 14.1 (Android 7.1.1)
    on a NookHD or NookHD+


    Code:
    • I am not responsible for bricked devices, dead SD cards, thermonuclear war,  or you getting fired because the alarm app failed.
    • If you have any concerns about features included please do some research before flashing anything!
    • YOU and YOU ALONE are choosing to make these modifications.




    Cyanogenmod builds are available but Not recommended because it hasnt been updated since December 2016)
    This guide works for the NookHD (Hummingbird) & NookHD+ (Ovation) Files for the NookHD+ (Ovation) can be found in post #2
    It has been reported that the Nook's are picky on which SD cards will work with this "method", if you have issues try formatting the SD card, if that doesnt work try other SD cards.




    Known Bugs & Issues:

    Nook HD (Hummingbird)


    AOSP:




    • When you enable Wifi it wont auto connect, how to fix this:

    turn off wifi, turn on wifi (wait to see if it auto connects) forget your network, connect to your network, repeat steps until wifi auto connects.



    • Restarting your Nook will boot into Twrp, Solution: use the Power off option instead





    • Using the "Power Off" option in power menu will just Restart the Nook instead of powering off, Solution: reboot into TWRP and choose "Power Off"



    LineageOS:



    • one random .apk file (the .apk seems to be different for each person) will refuse to install due to "lack of storage" theres no known workaround.



    • Using the "Power Off" option in power menu will just Restart the Nook instead of powering off, Solution: reboot into TWRP and choose "Power Off"


    • Screen mirroring using "scrcpy" may cause the device to freeze and require a force shutdown by holding the power button


    Cyanogenmod:
    • Theres no known bugs or issues



    NookHD+ (Ovation)

    Nothing has been reported yet, if you find any bugs please report them & any possible soultions





    What's needed:

    your Nook HD or NookHD+ (make sure it's charged before doing this)
    A micro SD card (its recommended to use 16GB+ micro SD card)
    A micro SD adapter (only needed if your computer doesnt have a MicroSD card slot)
    A computer




    Step 1:
    Obtain the files

    download Win32 disk imager, it can be found here
    (Ignore the other files)




    The next files for the Nook HD are at the end of this post, for the Nook HD+ see post #2:
    (If the files i provided stop working check out the sources)

    Now is the time you need to pick your ROM:

    (NookHD hummingbird)

    aosp_hummingbird-7.1.2-20181227-1604.zip is the Aosp ROM

    cm_hummingbird-ota-NMF26Q.161222.zip is Cyanogenmod

    lnos_hummingbird-ota-NJH47F.181223.zip is LineageOS

    (NookHD+ Ovation)

    aosp_ovation-ota-N2G48H.181223.zip,

    lnos_ovation-ota-NJH47F.181223.zip,

    cm_ovation-ota-NMF26Q.161222.zip,




    Other needed files:

    (NookHD hummingbird)

    NookHD-bootable-CWM-6027-for-emmc-stock-4GB-rev3-(02.03.13).zip is the recovery that is used on the SD card,

    twrp-3.0.1-0-hummingbird.zip is the verison of Twrp that is used just to get twrp installed on your Nook, its updated later in the guide with this one:

    twrp-3.1.1-0-hummingbird.img is the verison that will be used permanently
    (later versions have issues, bugs or wont boot)

    (NookHD+ Ovation)

    emmc-cwm-early3.1.img.gz,

    twrp-3.0.1-0-ovation.zip,

    twrp-3.1.1-0-ovation.img,



    Gapps aka Google play store/services (optional)

    You can download Gapps from https://opengapps.org/
    If you don't know what to to do choose these options:
    Platform: ARM
    Android: 7.1
    Variant: Pico
    (If you have issues you might need to download a older version)


    To install Gapps you will need two extra files:

    (Note: DO NOT change the file names of the two files, the file names are important)


    For Nook HD (Hummingbird) grab:

    lanchon-repit-20170115-factory=32M-system=1G-cache=32M+wipe-data=max-hummingbird.zip


    For Nook HD+ (Ovation) grab:

    lanchon-repit-20170115-factory=32M-system=1G-cache=32M+wipe-data=max-ovation.zip


    For both the Nook HD & Nook HD+ grab:
    delete-backup-of-stock-rom-hummingbird-ovation.zip


    (Note: these files are needed for a additional step you will have to take to get Gapps installed, the extra step is explained later on)





    Step 2:
    Extract this file:

    (NookHD) NookHD-bootable-CWM-6027-for-emmc-stock-4GB-rev3-(02.03.13).zip

    (NookHD+) emmc-cwm-early3.1.img.gz

    (its 3.8GB extracted to make sure you have space on your computer and it might take a few minutes)
    After extracting it you should get a .img file



    Step 3:

    install win32 disk imager (if your on Mac or Linux you might need to find alternative software) then run it, insert your SD using using a adapter or native micro SD slot, now you should be presented with something like this
    2017-02-26_13-39-01.jpg

    Under "device" you will see a drive letter make sure its set to your micro SD and Not anything else (you can check the drive letter of your micro SD card using your file manager)

    Now under "image file" choose the .img file from step 2 then click "write",

    This will Erase anything on your microSD card so make sure you get your files off of it before proceeding,

    after that's done drag and drop the:
    ROM, Twrp zip file & Twrp .img file, and optionally Gapps and the extra files needed to install Gapps
    onto the micro SD card using your file manager,
    after you copied the files eject the micro SD card from the computer.



    Step 4 (installation)

    Power off your Nook HD, then insert your micro SD into the microSD card slot,
    now hold the power and "n" button at the same time once the screen comes on let go of the power button keep holding the "n" button until you see this screen
    wp_20160803_10_48_17_pro1.jpg


    Once you see Cyanoboot let go of the "n" button and wait until it boots into the recovery once it gets past the cyanoboot screen you should see this screen:
    wp_20160803_10_53_00_pro1.jpg



    (Use volume buttons to go up and down, power button to back out 1 menu, "n" button to select highlighted option)

    now select install zip, navigate to "external sd" now install the Twrp zip file (3.0.1.0)

    once that's done back out the first menu remove your microSD card
    (Removing your microSD card won't force shutdown the nook)

    after your microSD card is removed select "Reboot system now"
    if asked about disabling stock recovery select Yes, if asked about root select No,
    (you can get root later if you want)


    once your nook turns on again hold the power button until it turns back off, once off hold power and "n" button let go of power when nook turns on then let go of "n" button when "Cyanoboot" appears

    (If your nook doesn't want to turn on when holding the key combo:

    Hold the power button, The second the screen turns on let go of the power button & hold the "n" button, keep holding the "n" button for five seconds after the "Cyanoboot" screen appears)


    Now you should boot into Twrp, once in Twrp insert your microSD card

    (until you format the SD card you will need to remove it when rebooting or else you will reboot into the recovery on the microSD card)
    (Note: it is recommended to choose the Power Off option in Twrp instead of Reboot because then you can safely remove your microSD card when the device is powered off then reinsert it when back into Twrp)
    (after you have completed this guide & formated the SD card disregard this note)

    Now select "install" (Twrp uses touch screen)
    then navigate to "external sd" now in the bottom right you will see "install image" button select that,

    Now select the Twrp .img (3.1.1.0) on the "swipe to install" screen you will see 2 options "recovery" and "boot" select recovery then swipe to install,

    (if it failed to install back out to the main menu select "reboot" then "power off" once you nook is off go back into twrp using the key combo then try installing the Twrp .img file again)

    once the Twrp .img file is installed back out to the main menu now select "reboot" then "power off" then get back into Twrp using the key combo,

    Now it is time to do a "advanced wipe" from the main menu select "wipe" then "advanced wipe" now select the following:

    "Dalvik/ART cache"
    "System"
    "Data"
    "Internal Storage" (optional)
    "Cache"
    (DO NOT select microSD card or else you will lose the files you need)

    After selecting all of the things listed above (NOT microSD)
    "Swipe To Wipe" and wait until it finishes,


    ==========================================================================
    The section below is for instructions on how to make the nessasary changes to install Gapps, Skip it if you dont want Gapps.
    ==========================================================================


    If you choose to install Gapps you will need to resize some partitions which is explained below,
    In the event that something goes wrong and you dont know how to fix this process going wrong ask for support, or visit this Github Repository and see if they have the answer.


    How to resize the partitions to allow the installation of Gapps:


    • Delete backup of the stock ROM

    There is a backup of the Stock ROM that needs to be deleted to free up some space

    On Twrp's homescreen go to "install", now find:

    delete-backup-of-stock-rom-hummingbird-ovation.zip

    and install it,




    • Resizing the partitions to allow Gapps installation

    Now it is time to resize the partitions,

    On Twrp's homescreen select "install", find:

    lanchon-repit-20170115-factory=32M-system=1G-cache=32M+wipe-data=max-_____.zip

    And install it,

    Note: because this file is resizing partitions it may take a while, i recommend plugging in your charging cable and leaving it alone,
    DO NOT interrupt this process, Stopping this process could courrpt the "/data" partition,
    If the file fails due to a issue with mounting partitions it should make a copy of the file in "/tmp" and suggest flashing it from there, try the file in "/tmp" if this is a issue.


    (Note: Wiping the partitions will Not restore the partitions back to default)


    ============================End of Gapps Guide==============================



    Once that finishes back out the main menu and select "install" navigate to "external sd" then select your ROM and if you want Gapps select "add more zips" then select the Gapps zip,


    Now Swipe to install, after your ROM & Gapps (if you chose to install Gapps) is installed remove your microSD card then select "Reboot"

    after that it should boot into your new Custom ROM, give it 5-10 minutes for first boot,
    Now your done! Enjoy your new Custom ROM.



    If something is to ever happen and you are unable to access Twrp or your ROM, follow these steps:
    • follow Step 3 again,
    • after following Step 3 boot to your SD card,
    • install the Twrp .zip again,
    • once Twrp is reinstalled remove the SD card and reboot to Twrp,
    • in Twrp insert the SD card, install Twrp .img (3.1.1.0), remove SD card & reboot back into Twrp,
    (Skip the next steps if your ROM is still working)
    • once your back in Twrp, insert the SD card,
    • advanced wipe everything, (except the SD card), flash your ROM (and optionally) Gapps, then remove the SD card & Reboot.



    Note: on boot your Nook will show the Nook "splash screen" then the Cyanoboot "splash screen" then your ROM "splash screen" this is normal dont worry about it.

    (You can now format the mircoSD card used for this install process)

    Finally got the darn thing working. I had tried "aosp_hummingbird-ota-N2G48H.181223" that I got from another thread, and that one had the same issues as the Lineage build from OP's post for me. I just flashed "aosp_hummingbird-7.1.2-20181227-1604" from this thread and now the storage issue appears to be gone. I haven't tried flashing it with GAPPS yet. I appreciate you guys trying to save my sanity.
    I'm glad you got it working. Now you have everything you need; a stock ROM, a custom ROM, and knowledge on how to resize the /system partition. You should be able to get the Nook HD exactly as you want it.

    Thank you Merazomo! Is this process just to expand the partition then install Gapps or is it a complete install of lineage os plus expansion of the partition? Thanks again :).
    I've only had to do it once given there aren't any newer ROMs out there for the Nook HD+; therefore, I haven't done it again since the first time I did it, so I don't know if the zip can be installed without any consequences to your current LineageOS ROM. I did it when I already had a rooted Android Nougat ROM installed on my Nook, so it seems all that zip file does is expand/resize and move around partitions to make enough room to be able to install Gapps. In theory, nothing "should" change from your current setup; I can't confirm it though. Backup everything you have right now and give it a go if you want. There's another zip file in the guide to return all the partitions to their stock default layout in case anything goes wrong. Again, for me all the zip file did was increase the /system partition leaving my Nougat ROM intact but I've only done it once.

    I also tried to install Gapps at the same time but it would let me. I tried to install PICO as you suggested. I believe the message I got was that there wasn't enough space on my Nook. Is there another version of gapps that you can recommend? And the steps to install post rooting my Nook? I did a factory reset prior to converting my Nook so surprised when I got this message. As always your help is greatly appreciated :)
    That issue was very common with later versions of Nougat. The problem is the /system partition; it's not large enough for Gapps. You have to use this guide to make it work: https://github.com/Lanchon/REPIT/issues/59. This zip file expands the /system partition to 1GB so that you don't have to struggle installing Gapps due to size limitations. Just follow the links in the guide for downloading the proper zip file. It should be named "lanchon-repit-20170115-factory=same-system=1G-cache=112M+wipe-data=same-ovation.zip" or something like that. That zip file has to be flashed/executed from the internal /tmp location at TWRP; it won't work if you flash it from a MicroSD card, it has to be moved using the: advanced > file manager > copy > /tmp at TWRP first, before being flashed from the /tmp location. It took me many tries to get it right as it wasn't something I had to do on my Nook HD+ when using Marshmallow. It takes a while to flash, but afterwards you should have enough space at the /system partition to install any Gapps file you want. You should probably give that guide a read before trying anything though.
