Ditto. As mentioned in the second post, some older versions work while the most recent do not. I recently had my little SIM-less KitKat phone I use as an mp3/audio book player trashed by an update of the Google app (of all things). Took me awhile to track down and fix the issue with an older version--now set to NOT update.

Edit: if you locate a working version please let me know so I can add the info to the second post.

i found my nook tablet lying around after a long time.. It is rooted but with the orginal Nook OS.. Will be able to flash Android 7.0 using the above method?

Also, what is the SOT you are getting with this ROM on Nook Tablet?

Cheers!!!!
[Barnes & Noble Nook Tablet] nmyshkin:
Yes, assuming it's a 16 GB model.

SOT?

Edit: Aha. I learned something today :) ScreenOnTime is about 8% on my tablet. As a disclaimer, I do not like screens that are bright enough to bore a hole in your retina, so YMMV

As a temporary solution, I installed another calendar (Day By Day) on my Tablet. It works well by itself, but doesn't want to sync with Google Calendar. I checked Google Calendar on my PC and nothing has been lost and nothing has been synced. The more important calendar location for now is my Tablet. Day By Day's widget works fine so I can see what's coming up over the next couple of days. So it's O.K., for now.

I'm looking for prior versions of the Google Calendar app at the link shown above, but I haven't loaded any of the APKs on my Tablet yet. I did set Playstore to not auto-update, as recommended. If I find a "good" prior version, I'll post it here. maybe someone will beat me to it.
[Barnes & Noble Nook Tablet] mac4rfree:
Even I tried to install the LNOS to nook tablet.. Even I faced the same issue.. So I logged in to recovery and mounted the system.

And then I selected Advanced.. File manager.. But when I tried to copy/move the /system/media to sdcard. Its throwing an error.

Can u help me out here.

Cheers!!!
[Barnes & Noble Nook Tablet] mikeataol:
I never have an actual sdcard in the unit....

in TWRP , mount system, then in file manager I copy / move /system/media to /emmc (internal storage.....)
[Barnes & Noble Nook Tablet] nsfgp:
I never copied it back. I think I deleted the directory after some try and the copy to the SDcard probably had to some issue too. Don't think you need those stuff in there. So try again to remove it and see if you can proceed with the GAPPS install.

Good luck.
[Barnes & Noble Nook Tablet] jglen490:
O.K., I've tried but no calendar that is supposed to sync with Google calendar works on this platform I have Moto G (2nd Gen) running Marshmallow (6.0) and it syncs and everything runs smoothly. Since this Nook Tablet doesn't properly handle a calendar sync with this version of Nougat (7.0), even after trying a couple different apps and different versions of Google Cal, it's time to go look for the old CM 10 related files and reinstall. Nice try, and otherwise a great experience, but it doesn't quite meet expectations.

Thanks for your efforts!
[Barnes & Noble Nook Tablet] nmyshkin:
It may be that the pico GApps package is missing something that cannot be obtained from a PlayStore download. I guess you could try the next step up (nano?). I remember reading at the opengapps site about the various options and there seemed to be the implication that some things would not work if you chose one of the smaller packages. Just a thought.

Edit: I take that back. A visit to the opengapps site reveals that the calendar sync is supposed to be part of the pico package.

Edit-Edit: OK, so I just made one change and then installed Google Calendar. I was able to create an event which showed up when I accessed the calendar on my PC and while there I created another event which showed up when I reopened the app on my tablet. I've never used GC before, so maybe I'm missing something, but....

Here's the change: look at /data/system/sync/accounts.xml. There should be a line somewhere for the account you want and Google Calendar. On mine the "enabled" option said "false". Now I changed it to " true" before installing the app. Not sure if it matters when the change is made.
[Barnes & Noble Nook Tablet] jglen490:
O.K., I'll check into that before I nuke 7.0 :good:

I'll update tomorrow after the Tablet recharges - and I do, too ;)
[Barnes & Noble Nook Tablet] jglen490:
So I tried getting to that file, but I couldn't. I checked to see if phh superuser was installed, and it looked like I forgot to do that step. So I went to the Playstore to download, and the download failed " Can't Install App". I went through the troubleshooting steps, but found nothing that would impede the download. Is there another app I can install to gain superuser permissions?
[Barnes & Noble Nook Tablet] mikeataol:
to get superuser, this must be flashed from recovery

addonsu-phh-arm-new.zip (796.6 KB) attached

(from [MENTION=4473900]amaces[/MENTION] box folder) https://notredame.app.box.com/s/26a4bygh9vbaw7jjq08xr5evomvaw5ww

and the apk then installed in Android (attached)

Superuser_1.0.3.3.apk (1,017.4 KB)
[Barnes & Noble Nook Tablet] nmyshkin:
Is this new because of a change in the apk itself? If so, I should update the first post instructions :eek:
[Barnes & Noble Nook Tablet] mikeataol:
I don't know if it's "required" to flash the new supersu zip file.... I'm just in the habit of doing it I guess
[Barnes & Noble Nook Tablet] jglen490:
Well addonsu-phh-arm-new.zip flashed from recovery, but Superuser_1.0.3.3.apk would not install. Error says it conflicts with an existing package by the same name. Using Total Commander I searched for anything with "superuser", but the only things that came up was the apk I was trying to install.

---------- Post added at 11:40 PM ---------- Previous post was at 11:17 PM ----------

And one other thing. I tried to go to /data/system/sync/accounts.xml, however there was nothing below /data - no files, no folders.
[Barnes & Noble Nook Tablet] mikeataol:
are there any "superuser" apps in your app drawer?

you are running the aosp rom from the original post?

whatever file manager you are using needs root

the built in one needs to be started in "root mode" or in ES file explorer flip the switch to enable root mode.

/data is on "device", not to be confused with the one in "internal storage"

aside from all this, in "accounts" google account /sync settings ... is calendar in there on your google account?
[Barnes & Noble Nook Tablet] jglen490:
I went back and re-started the process. I found my install SD card, made some notes about what was installed, plugged in the card, and started at step 3 of nmyshkin's instructions. Between the install aosp_acclaim-ota-NBD90Z.161020.zip step and the install appropriate opengapps zip step I flashed addonsu-phh-arm-new.zip, then pico gapps. Then I signed into the installation and setup wifi and whatever else came next.

I noticed that the SD card icon was still showing at the top of the screen, so hit that and set it up as file transfer, which let me explore the card. I hit the icon for the Super user apk and it installed! So I did the setup on the app.

Now I'm re-installing the rest of the apps I had an hour ago. As soon a as I get Google Cal installed, I'll try the sync process - which is what stared this whole mess in the first place!

Thank for pointing out where /data is - there are a few "/data" folders. Check back with you.

Just installed Google Calendar. It immediately synced, and didn't crash on refresh.
[Barnes & Noble Nook Tablet] nmyshkin:
Yipee!
[Barnes & Noble Nook Tablet] jglen490:
Yep, me too!! It continues to work just fine after the re-install. Thanks much guys!

:D :good:
[Barnes & Noble Nook Tablet] reubdog30:
Hello, I have a Nook tablet and I've downloaded all the requisite files listed in the post. However when I go to upload the aosp acclaim zip it tells me that it cannot be uploaded because this is an encore device. Is there anyway to rectify this?
[Barnes & Noble Nook Tablet] mikeataol:
HI,

The NOOK encore isn't the Nook tablet.

it's the predecessor to the Acclaim, the NOOK "Color"

it looks similar, but has much different hardware.
[Barnes & Noble Nook Tablet] reubdog30:
So is there anyway to update the Nook Encore? Or should I just go head and get a Nook color or HD to jailbreak? I was just trying to not have to buy a new smaller tablet lol.
[Barnes & Noble Nook Tablet] mikeataol:
I think the latest good rom for the Color is CM11, but I haven't used the Color in a long time.

You can build an SD card based KitKat for the Color pretty easily , to gauge what it's like

see: https://iamafanof.wordpress.com/201...oid-4-4-2-for-nook-color-22dec2013/#more-1861

You might have some difficulty getting the downloads for anything Cyanogenmod based as they are dfunct, but that SDCard version will at least get you on something closer to modern....

EDIT: so even that SDcard file isn't downloadable anymore , as it was hosted on goo.im which is also defunct

I looked and don't have a copy of it...

You might read around in the Color forum to see whats available.

https://xdaforums.com/nook-color

Edit2: I do have an SDCard version of CM11 for encore if you need one.... but I would recommend you poke around in the Color forum
[Barnes & Noble Nook Tablet] nmyshkin:
I believe [MENTION=4190710]drmarble[/MENTION] has worked up CM13 and Lineage ROMs for the Nook Color, both experimental and neither capable of supporting GApps.
[Barnes & Noble Nook Tablet] MarekAlons0:
Im have a doubt

I'm confused, this rom works for nook tablet bntv250a?

or only works for nook tablet 7'
[Barnes & Noble Nook Tablet] nmyshkin:
This ROM is intended for BNTV250 (no "a"), the 16 GB model. It is definitely NOT for the Nook 7.

The ROM will run on a BNTV250a but not with GApps. I've been working with an 8 gb tablet for a few weeks now, trying approaches for ROMs past CM11--including PlayStore access. Stay tuned for a new post.

Edit: See https://xdaforums.com/nook-tablet/general/how-to-cm-11-8-gb-nook-tablet-bntv250a-t3667555 for a method to obtain PlayStore access without GApps as well as an evaluation of post-CM11 ROMs for the BNTV250a
[Barnes & Noble Nook Tablet] komedol:
I did all that except step 3.f. - [(Optional] Select Advanced Wipe, Repair or Change file system; select "data" (only) and change file system from ext4s to f2fs (supposedly a faster format--if you decide to undo all this, you should probably reformat "data" to ext4s)).

After I'm done, still no superuser app in the drawer, so I tried:

1. Installing that superuser 1.0.3.3 apk - it says App not installed - package conflicts with an existing package by the same name

2. Installing SuperSU from Google Play - it can be installed but when running it says "SU Binary occupied"

3. Installing phh's SuperUser - it says "Can't install app"

So I tried installing Root Checker and Titanium Backup from Google Play to check whether I have root access, and those apps say I don't. But when I installed Solid Explorer, I have access to Root.

Now I'm confused. Is my NT properly rooted? Because I want to install Titanium Backup and without Root the app won't work.

Thanks.
[Barnes & Noble Nook Tablet] nmyshkin:
So there are different opinions about this. When I did my installation I followed the instructions as given (3f does not matter for your purposes). That means I installed the me.phh.superuser.1033.apk from the PlayStore after a first boot. That was all I had to do for root. The app appeared in the drawer and I was able to configure as desired.

Here's where I point out that this is a kind of unique ROM. It lacks the shutdown bug that affects all others and for some reason it disappeared from [MENTION=4473900]amaces[/MENTION] folders not long after it appeared. Some people say that you need to flash the addonsu-phh-arm.zip from https://notredame.app.box.com/s/26a4bygh9vbaw7jjq08xr5evomvaw5ww/file/185013260718 first (while you are flashing the ROM and GApps) and then install the me.phh.superuser.1033.apk from the PlayStore. This is certainly true about current AOSP ROMs, but it's not what I did.

So...if you're having trouble, you might try flashing the zip and then installing the app. I hope that sorts it out for you and I'm sorry it didn't behave the first time around :(
[Barnes & Noble Nook Tablet] komedol:
No worries, thanks to you I finally got the root working. So I backup the NT, clean wiped it, then re-flashed the ROM + addonsu-phh-arm.zip + GApps (while in between "recycling" the TWRP - in reference to your magisk post), after it's all done I installed the superuser.apk, and voila it works! Many, many thanks for your guidance and help :good:

bad boot image magic

Hello,

I know this is an old topic but I recently acquired a nook tablet 16gb and wanted to root it so I found this guide and followed it to the "T". Upon booting up i get an error in red: "bad boot image magic". Does anyone know why and how to correct this? Thanks in advance.
[Barnes & Noble Nook Tablet] nmyshkin:
Is that the only error you got through the entire process, i.e., trying for first boot?

This unfortunately exceeds my technical know-how but if I had to guess I would say that maybe one or more of the 3 original cyanoboot files used to prepare the SD card needs to be checked and the process repeated. Unfortunately. I've done a search on the forum for this error message but nothing useful turned up. Can you boot into recovery (hold down the "n" button as soon as the message appears at the bottom of the cyanoboot screen)?

Edit: another thought. You say you "recently acquired" the tablet. Was it running stock when you got it?
[Barnes & Noble Nook Tablet] lostdongle:
Thanks for the reply. Yeah as soon as it boots into the boot loader, it throws up that error and pressing "N" does nothing. Prior to trying this I did a factory wipe on the system so it was completely stock.
[Barnes & Noble Nook Tablet] nmyshkin:
Did you do the change from ext4s to f2fs for the data partition (

only

)? If you inadvertently changed the format for any other partition I could see a problem there. TWRP on a touch screen is so squirrely it's easy to get something you don't really want.

Obviously, if all else fails you prepare the SD card again and give it another try. I had issues when I flashed CM 10.2.1 long ago and had to redo it several times before the device would behave. If you try this and there is still no joy then I suggest a post with the title of the error message. Hopefully someone who understands will spot it. I wish I could be of more specific help :(
[Barnes & Noble Nook Tablet] ShapeShifter499:
I just did this and nearly pulled my hair out over making the SD card. Tried three different cards with different speeds. Turns out setting the patition's boot flag made it work, I did this with fdisk in Linux. Make sure the boot flag in enabled if anyone is trying to make a boot SD for the first time.
[Barnes & Noble Nook Tablet] KenithO:
Thanks for the tip!!! May be reason mine did Not work!!!

Any suggestions how to set the partition's boot flag using Windows?
[Barnes & Noble Nook Tablet] ShapeShifter499:
Attach your SD card to the PC. Bring up "Disk Management" and find the partition that represents your SD card, it should have only one partition and it should be formatted Fat (aka Fat32). Right click the partition and select "Mark Partition as Active", make sure to click yes to any warning screens. Safely eject the SD card and try again. Please let me know if this works for you.

You might have to type into the search of your desktop and search for 'diskmgmt.msc'

Or go to 'run' and type in 'diskmgmt.msc'

Or if you're on Windows 10, right clicking the start menu icon (the windows logo) should bring up a menu that has the "Disk Management" option.
[Barnes & Noble Nook Tablet] nmyshkin:
Or, if you are using Mini Partition Wizard to set up the card from the get-go, you can set the Active flag from its menu. Just don't forget that when you do things with MPW, nothing actually happens until to tell it to. You just build up a list of stuff you want done and none of it happens until you finally say "go".
[Barnes & Noble Nook Tablet] nmyshkin:
Thanks!

Thank you to the kind anonymous member who gifted me with a month Ad-free :)

I'm glad you found the instructions at the beginning of this thread helpful.
[Barnes & Noble Nook Tablet] komedol:
Thanks to OP, I've managed to install AOSP 7.0 on my 16GB Nook Tablet. But now I have this really annoying problem: dead/unresponsive screen on top and bottom of the screen in portrait mode. So when I try accessing navigation bar or notifications bar in potrait mode, the screen is unresponsive.

Reading this (http://bishoptec.com/2012/06/how-to-un-brick-a-nook-tablet-8gb-or-16gb/ - in the comments section), it may be related to the "multi-touch bug". Hoping that it's true and it's not hardware-related issue, I tried to:

1. Clean re-flashed AOSP 7.0 (factory reset, wipe everything, then following the OP guide in the 1st page) - didn't work, still have this problem. When I accessed the touchscreen firmare flashing app, it says "current firmare: cerror detecting flashing denied" and I can't access anything.

2. Re-flash the original firmware from B&N - didn't work either; the touchscreen is completely dead after installing it

Now I ran out of ideas. Is there anything else I can do to fix the deadscreen problem?
[Barnes & Noble Nook Tablet] LKJEFoi234:
Excellent guide, OP. Does anyone know how long the "android" screen goes during the first boot? It's been booting for an hour so far. Thanks.

Edit: I ended up re-doing steps e. to n. in OP, selecing 'wipe dalvik/cache' after each install though. Then it ended up booting properly after a couple minutes.
[Barnes & Noble Nook Tablet] nmyshkin:
I'm glad that worked out for you. On some days it seems like there's far more art than science to this process, almost as if each device retains some vestige of what's been done to it before and so is in some way unique.
[Barnes & Noble Nook Tablet] LKJEFoi234:
Latest Stable Magisk Working Great

Thanks so much again, nmyshkin. Really liking using the Nook with this. I couldn't get the PHH SuperUser app to pop up for 'granting superuser access' even though I installed it from F-Droid (couldn't find it in Play Store). Also the addonsu-phh-arm.zip file link is gone since I downloaded it a few days ago. I ended up flashing the latest Magisk + manager, and it's working great. Thank you for an excellent guide.
[Barnes & Noble Nook Tablet] KnightRid:
Hi, I was trying the guide here to get this old Nook Tablet running to use it just as a control unit for the google home units I bought and I keep getting an error when trying to install the twrp 3.0.2 zip - it just says E:Unable to mount '/bootdata' and never lets me reboot into it. I have tried 7 times now and even manually tried to mount the bootdata but every attempt gives the same error. I have searched to no avail (one person said they rebooted and removed the sdcard and then it worked but I even tried that before posting to no avail lol)

Does anyone have any idea what I am doing wrong?

Is it just TWRP being stubborn with the sdcard?

I did do the backup to the sdcard (step 3b optional but recommended) but I am wondering if I should have used the internal to hold the backup rather than the sdcard. I think I will wipe everything and start fresh on the sdcard and try to back it up to the internal rather than the sdcard just to see what happens.

Update 6-25-2019 - Try 2 (Lets see if I click the POST REPLY button again and delete everything so I have to redo a third time) - Ok, did not matter about backup it is doing the same thing. I tried 6 more times and still that exact error. I thought I would be able to find information on that error online but it doesnt seem to be a very popular one. I will try and find another micro sd card around here somewhere to try and see if that is the problem. Using a Sandisk Ultra 16gb since I figured Sandisk would cause no problems....
[Barnes & Noble Nook Tablet] saq-xda:
I was able to do this with the unlegacy Android build. It was a bit of a blind crawl - I used the repartition script then formatted and installed the UA build, but in the latest versions I didn't have space for even Pico. Turns out the install was putting in a smaller-than-partition sized filesystem and using TWRP's "resize partition" (found in wipe/advanced wipe) on /system bumped it back up to the bigger 14.1 size and, after a restart, allowed me to flash gapps nano.

What I have had ongoing problems with is the touchscreen not working right in TWRP 3.0.2. Doesnt register touches sometimes or registers multiple/long touches. Keyboard/shell is practically unusable because of it unless I plug in to ADB or Fastboot. Ah well, UA is on and I shouldn't have to use it too much, right?
[Barnes & Noble Nook Tablet] nmyshkin:
TWRP 3.0.2.....UGH. Yes, miserable touch-screen madness. If only there were a CWM recovery version available for this level of OS.
[Barnes & Noble Nook Tablet] saq-xda:
It's something peculiar to the Nook touchscreen (and don't know if it extends to the HD or not). I have an Amazon Tate and Samsung Galaxy Pro Mondrian with TWRP and it works just fine on those.
[Barnes & Noble Nook Tablet] 1337haXXor:
I have 2 identical nooks I'm working on. One completed fine and had no issues (though I had to use Pico GApps), but the other one has a peculiar issue: the volume + and - buttons won't scroll on the boot menu, so I have no way of getting into the various recoveries... Any solution?

EDIT: Well, booting into the device normally has made me realize that the volume keys just plain don't work.. Dang, is there no other way to navigate the boot menu? Via adb or something?
[Barnes & Noble Nook Tablet] nmyshkin:
It sounds to me like you are either SOL or maybe need to try one of the rescues back to stock. If it's a true hardware issue, returning to stock will not solve it. Otherwise, it's a way back into the process with a clean slate. Are are you referring to stock when you say "booting normally"?
[Barnes & Noble Nook Tablet] pokemonrocks9:
I keep having an issue during install during the Gapps part. I keep getting error 70 even with the pico opengapps. Ive tried running the resize in twrp as well. Any advice here?
[Barnes & Noble Nook Tablet] nmyshkin:
Following the instructions exactly as written (with all the extra reboots, etc.) I never had any trouble with pico GApps. Are you sure you are working with a 16 GB model? Have you done any partition resizing in the past?
[Barnes & Noble Nook Tablet] pokemonrocks9:
It is the 16 GB model and honestly it may have been repartitioned maybe at some point before I got it. The system section is about 600mb with 200ish mb free before Gapps install. I ended up installing the Amazon app store as a placeholder.
[Barnes & Noble Nook Tablet] nmyshkin:
I'll have to fire mine up tomorrow and check those numbers. You could do a microG number instead. The device should have enough resources to run the actual PlayStore app with microG. No purchased apps, though.

Or maybe it is not repartioned. When I got mine I took it to B&N to have them repartition the device, but I think that was for the user area, not system.
[Barnes & Noble Nook Tablet] pokemonrocks9:
I'll give it a shot. Much appreciated.
[Barnes & Noble Nook Tablet] nmyshkin:
I'm not sure this is going to be helpful except to suggest that something is not right--which you already suspect.

I did a busybox df /system and it shows 617 MB for the partition, with 486 MB used (79%). That's with the pico GApps install. I don't think I really have a lot of other custom system apps, so what's there is from the ROM itself as well a GApps.

Busybox df /data shows that partition at 5.9 GB with about 77% used.

Like I say, not helpful except to suggest there should be plenty of room.
[Barnes & Noble Nook Tablet] pokemonrocks9:
Yeah definitely odd. The only difference I can think of is the many year newer version of Pico or mine has something odd in it's system files causing issues. I appreciate you looking into it though.
