Good day dear Gents, speccialy to Mr. Nmyshkin,

Thanks for all these shares for the article with B&N NOOK Tablet. Few days ago I took out from the old carton box my Tablet BNTV250, which was with Software Ver.1.4.3 and after official upgrade from the B&N web was updated to 1.4.4 and it turned out that nothing is working as years ago. B&N support team responded that they don't support this BNTV250 with more updates.

Going through all provided information here I was little shaken with the proper steps & sequences in precise details whch need to be followed with fresh update of all links for download. In order to avoid my troubles, could you please describe with copy/paste step by step what need to be followed and how to flash my original ROM in such way not to break something... what is required one by one PLEASE. I need to wake up my sweet baby old NOOK BNTV250 Tablet /not COLOR/ and to use it properly as best possible option with the most reliable and steady ROM... Is that ROM still CM 11? with 5 thumbs up?

Please, if there is some chance to provide all programs & software as attachments or with fresh links and info for easy way to follow, PLEASE!!!

I was going through so many youtube videos with broken links and old information and I really hope here I could be able to rise up my head from this hard waking up my Tablet process. Highly appreciate your support and time for sharing.

Best & kind regards to ALL!

First issue: are you saying that the 1.4.4 update failed to give you a working tablet?

Or were you just not happy with the old B&N interface?

Um...I thought that's what the first post is all about, a step-by-step procedure for installing a custom ROM. All of the links are current, AFAIK. The ROM choice is up to you. CM11 works great but you will have security issues with some internet sites and maybe some apps. I'm running CM13 on the BNTV250a and AOSP 7.0 on the BNTV250. If you have the 8 GB model (BNTV250a), CM13 is as far as you can go and there is a little instability.

Again, everything you need is properly linked in post #1. If you don't understand a particular step or are having trouble with it, then ask a specific question.

Hola: Thanks for your prompt response!

First issue: are you saying that the 1.4.4 update failed to give you a working tablet?

=Tablet is working, but not as usual before, without possibility to download from B&N web and many webs not working due to security issues....

Or were you just not happy with the old B&N interface?

=Not happy :( YouTube web is not loading requiring Android 4.0 or above...

on other webs:

The following problem I experienced after upgrading to last update ver. 1.4.4 for my Nook Tablet, Model: BNTV250

Data connectivity problem - "A secure sonnection could not be established"

In App Settings-Social-Manage your Accounts - "Updating, Please Wait..." and turning the circle for long time witout any success
[Barnes & Noble Nook Tablet] nmyshkin:
Right. And that is why--unless you are just going to use the tablet as a reader--most people will flash a custom ROM with an Android version higher than 2.3!

If you want to use YouTube, you're not going to be happy with CM11 (Android 4.42). The app will not run properly on KitKat. You might be able to use something like NewPipe (which I like), but I haven't tried it with CM11. Actually you may have issues with YouTube on many of the ROMs, especially if you have the BNTV250a. That's why people have been developing apps like NewPipe (there are several others out there).

OK. So you need to flash a custom ROM. Go back to post #2 and decide which ROM listed there will be best for you. If you have a BNTV250 (no "a") then any of the ROMs listed there will run OK, but I would still not recommend GApps beyond CM 11. It's just too greedy for a piece of hardware designed to run Android 2.3.

After you decide on a ROM to try, go back to post #1 and Look at the general procedure. You'll need to prepare a bootable microSD card to do the flashing (and potential backups) and you'll need to decide whether/how you'll use microG or GApps. All the steps are there. It's a mistake to read the entire set of instructions at once. You'll just overload. Take one step at a time and ask questions along the way if you need to.

Good day dear senior Nmyshkin, thanks for your support.

All day this web site was under transitional process and access was limited without authorization to write & post comments... As attachment is the printscreen. All day I was rooming around the web and youtube playing with "win32diskimager-1.0.0-install" & "CWM-6.0.4.7-cooper" as faster and more comfortable way following the video explanations from youtube, but no luck or any success :(

Your file of CM 13 whch I decided to use, because you stated that you hold the same in your Nook was downloaded as *.zip but not as *.img image file... It was far away from me to get described steps in post #1 Looking at the general procedure... Is there some chance to share a video or more detailed explanation, sorry for my total misery :(((

What is the difference between BNTV250 and BNTV250a? I see mine Model number is: BNTV250 on the screen in About Yr Nook... All day was my lost in action :(
[Barnes & Noble Nook Tablet] nmyshkin:
You need to prepare a microSD card for flashing/booting recovery mode and ROMs, (perhaps) GApps, etc. You can't do

anything

without that. Have you done this:

If not, which part is giving you a problem?
[Barnes & Noble Nook Tablet] aykov77:
==Right, microSD 16GB class (4) & another one 1GB as spare if needed... CM 13 as you stated in your NOOK, that is your preferred ROM in use

==almost everything :( no idea where to install, on my PC or inside of my Nook... point 3... 4... is not easy as CM in image file with TWRP or CWM which is better than TWRP, even win32diskimage
[Barnes & Noble Nook Tablet] nmyshkin:
You keep talking about win32diskimager. I do not see that mentioned anywhere in these two steps:

As for CWM vs. TWRP, you need

both

. The oldest CWM is used initially to get the new recovery (TWRP for CM 13) onto the internals of the device. Once that is done, you use the internal (emmc) recovery (TWRP) to flash the ROM. Jut make sure you get the version of TWRP I gave for CM 13.

But...first you need to get the card prepared. No win32diskimager anywhere in that.

Edit: also, BNTV250 is the 16 gb model You could install AOSP 7.0 without problems. Separate thread on that just below this one in the forum. Card preparation is the same except for TWRP version.
[Barnes & Noble Nook Tablet] aykov77:
==Right, microSD 16GB class (4) & another one 1GB as spare if needed... CM 13 as you stated in your NOOK, that is your preferred ROM holding in your Nook BNTV250a... what is the difference between 250 & 250a? 250a is 8GB, 250 is 16 GB? Mine Nook is only 1.07 GB, where is the so called 16 GB tablet bntv250???

==almost everything :( no idea which program where to install to create proper and good micro SD card... on my PC or inside of my Nook... point 3... 4... is not easy as CM in image file with TW o
[Barnes & Noble Nook Tablet] aykov77:
nmyshkin said:

basic instructions for creating an SD card that will allow you to try out these procedures. The excellent instructions by @digixmax here will get you started with the SD card. You need to follow steps 1-2 to prepare the card, although the version of TWRP you use will depend on the ROM you want to try out (see second post for links).

===== The excellent instructions by @digixmax here are having very bad feedbacks where not reliable response was coming from different users... :( It will be more easy I think if all reliable programs are in one place with proper instructions whish program to be installed on Win 10 PC, on microSD card, how and in what sequence... For you all is very clear and obvious doing this for many years, why no video clip in youtube what to to in proper sequence with all available software and applications... all such clics are either with brokel links, old version apps, missing CM13 and so on... working with imagination to think what to to with no success...
[Barnes & Noble Nook Tablet] aykov77:
Using a disk partition tool (such as MiniTool Partition Wizard Home Edition) create on SD card a Primary FAT32 partition, and set the partition ID type for the partition to 0x0C FAT32 LBA and set its Active flag. Once this is done, the partition should appear as a (read/write accessible) drive under Windows

=======

MiniTool Partition Wizard Home Edition I need to search in the internet, no link... and should install on Win10? ... 0x0C FAT32 LBA and set its Active flag.... where to be set ths partition... No clue at all :( ... This is a lot of information with is not in one place with many comments from different user for good or bad success... I'm really embarrassed... :(

2. Obtain and copy to the SD card the following files:

first MLO, then next u-boot.bin and flashing_boot.img in succulent_boot.zip obtained from https://www.mediafire.com/folder/xjwc1a482a6ll/Nook_Tablet

TWRP (TeamWin Recovery Project) version 2.6.3.0 or later, e.g., openrecovery-twrp-2.6.3.1-acclaim-sdcard.img from http://techerrata.com/browse/twrp2/acclaim, rename it to recovery.img before copying to SD card.

the flashable_CWM_6.0.4.5_chrmhoffmann.zip zip file from https://www.mediafire.com/folder/xjwc1a482a6ll/Nook_Tablet which contains the CWM recovery v0.2 provided by Chris Hoffmann (in the first post of the XDA Official CM11 thread http://xdaforums.com/showthread.php?t=2560827).

the zip file of CM11 ROM build of your choice from http://download.cyanogenmod.org/?device=acclaim (see http://www.cyanogenmod.org/blog/cm-11-m4-post-release-items for considerations in choosing nightlies vs. snapshot/stable builds).

the zip file of the Gapps package corresponding to CM11 – e.g., from http://wiki.cyanogenmod.org/w/Google_App

==================

so many links, complicaions and lost in brain functionality :( cray, crazy, crazy..... just for simple thing as creation of a microSD card...
[Barnes & Noble Nook Tablet] nmyshkin:
I'm not sure why you thought this would be a one-step process which anyone could do just by clicking on a link or watching a video. It's not. I was once where you are (sort of) and I had to learn by asking questions and trying (not always succeeding).

You just need to slow down. It's pretty clear you are not going to get this done in one hour.

Here is a link for MiniTool Partition Wizard: https://www.mediafire.com/file/0dax0o5yj7epxjz/pw102-free.exe/file

This is an older version (so don't update it no matter what it says). Newer versions lack the ability to set the proper things.

Install this on a Windows PC. I will prepare some images tomorrow to guide you through the set-up of the card. I'm shutting down for the day now.
[Barnes & Noble Nook Tablet] aykov77:
Could you attach please here the proper versions of both as you said CWM is used initially to get the new recovery and TWRP for CM 13, where to install and how to use, please. Many videos in YouT showing full flash & root of BNTV250 in 10 minutes time, but not with CM13 and with all links for download are broken... old reader is not supported by actual links :(... It was so easy to see some video with info & links, but no chance...

You said "You could install AOSP 7.0 without problems", why I need this when I'm going to use CM13?

Thanks Bro!
[Barnes & Noble Nook Tablet] aykov77:
You said to use the internal (emmc) recovery ... from where to get this and where to install???

(TWRP) to flash the ROM, same query ?
[Barnes & Noble Nook Tablet] aykov77:
Thanks, link was OK, file already installed on PC. Waiting for your guidance!
[Barnes & Noble Nook Tablet] nmyshkin:
0. STOP looking at stupid YouTube videos! They are all out of date and are just confusing you and getting you all hyped-up. Just follow my lead.

"1. Using a disk partition tool (such as MiniTool Partition Wizard Home Edition) create on SD card a Primary FAT32 partition, and set the partition ID type for the partition to 0x0C FAT32 LBA and set its Active flag. Once this is done, the partition should appear as a (read/write accessible) drive under Windows"

Translation:

a. format one of your 16 gb SD cards with Windows (see screenshot below). Just use the defaults. That should give you a clean card with FAT32 formatting.

b. Open MiniTool Partition Wizard (see screenshot below). When the program initializes you should see your SDcard at the bottom part of the screen and (probably) the single partition on it will already be Primary and Active (see screenshot below). So you only need to set the partition ID type.

c. Right-click on the description line of the SD card (line where the "Primary" and "Active" are). You will get a context menu. Select "partition ID type" (see screenshot below). If the defaults that come up don't match "0x0C FAT32 LBA" then use the small drop-down menu to select that option (see screenshot below).

d. Any time you use MTPW, none of the changes you make actually happen until you click on the big checkmark at the upper left corner of the screen (see screenshot below). So do that, wait for the changes to be confirmed and then quit the program.

When you have this done correctly, we'll go on to the next step.

Advice: making the card correctly is the MOST important step. A bad card will never work and will lead to endless tail-chasing and frustration, so take your time and follow the directions exactly.
[Barnes & Noble Nook Tablet] aykov77:
ALL Done! Ready for next. Thanks!
[Barnes & Noble Nook Tablet] nmyshkin:
Translation:

a. Download the following zip: https://www.mediafire.com/file/yv2pqev1akl8bfg/succulent_boot.zip/file

Extract

only

MLO, u-boot.bin and flashing_boot.img. Discard the rest. Copy these three files to the prepared SD card,

one at a time

,

in the order given

(don't just drag all three over as a group)

b. Download SD-card TWRP 2.8.6: https://dl.twrp.me/acclaim/twrp-2.8.6.0-acclaim-sdcard.img

Rename the file to "recovery.img" and copy to the prepared SD card.

c. Download the flashable TWRP 2.8.6: https://dl.twrp.me/acclaim/twrp-2.8.6.0-acclaim.img

Copy the file to the prepared SD card.

d. Download the CM 13 ROM zip: https://archive.org/download/cmarchive_snapshots/cm-13.0-20160819-SNAPSHOT-ZNH5YAO0IN-acclaim.zip

Copy the file to the prepared SD card.

e. (in preparation for microG) Download Xposed for Marshmallow: https://web.archive.org/web/2020110.../framework/sdk23/arm/xposed-v89-sdk23-arm.zip

Copy the file to the prepared SDcard

Optional:

If you will want to use Location services, you will need a flashable maps.zip. Download and copy to the prepare SD card.

That should complete the necessary contents of the SD card.

It would help for the next steps if I knew how much

you

know about setting up Android devices. For example, do know how to allow for the installation of apps from "unknown sources"? Do you know how to enable USB debugging or enable Developer Settings? Stuff like that.

Let me know when you're done preparing the SD card.
[Barnes & Noble Nook Tablet] aykov77:
===>Done!

===>Do you mean the surrounded in red circle in the attached print screen? if Yes, DONE!

===>Which one is the "flashable TWRP 2.8.6" among all links in the print screen???
[Barnes & Noble Nook Tablet] aykov77:
===>Done!

===>Done!

===>Done! "Location services" for what is this about, do I need it? or can be skipped?

===>No idea how much +I+know about setting up Android devices.

I think I know how to allow for the installation of apps from "unknown sources"?

===> That was somewhere inside of the settings, I could be able to find where to do alloing...

Do you know how to enable USB debugging or enable Developer Settings?

===> Here not so sure :(

===> Please, check present content of the transfered files available on the microSD card as per all above instructions

This is the TWRP you are missing: https://dl.twrp.me/acclaim/twrp-2.8.6.0-acclaim.img

Do

not

rename this one, just copy it to the card.

More tomorrow.

Thanks Bro, as long as you are aside doesn't matter how long it will take to wake up the ghost of my old Nook....
[Barnes & Noble Nook Tablet] nmyshkin:
You're good to go. More later this morning.
[Barnes & Noble Nook Tablet] aykov77:
===> Happy end to go :) for next.

What about CWM, not for use?
[Barnes & Noble Nook Tablet] nmyshkin:
Oh, oops.

I'm sorry. Glad you caught me. Download CWM and copy it to the SD card. You can delete the twrp-2.8.6.0-acclaim.img from the card.

Sorry for the delay. I've been busier today than I thought. Also trying to figure out a way to do screen caps in TWRP, but no-go, so it will be bad camera shots when I get there.
[Barnes & Noble Nook Tablet] aykov77:
===> Done! R u sure given link for CWM as "flashable_CWM_6.0.4.5_chrmhoffmann" is better than "flashable_CWM_6.0.4.8_chrmhoffmann", which one as version is better?

I have them both, see the attachment.

No probs bro, weekend is the private days for pleasure and emotions, whenever u have time, will be waiting for u!

Final content in SD card as attachment.
[Barnes & Noble Nook Tablet] aykov77:
==> Hi, thank you for entire comprehensive explanation for all about in small details, but I stucked up in the first section.

==> Here came the problem, all I did was as decribed, even to avoid troubles, I turned on the Nook with power cord inside to avoid troubles.

As an attachement is the print screen from the Boot Menu, where as active are only 1), 2) & 0). All other numberes are not active in faded out color, so "SDC Recovery" is inactive :(

After powering down & removing the power cord, I powered up again and the following message in red appeared "booti: bad boot imagemagic (in memory)" under in blue letters "(SDC) Loading Boot...". After powering down and turn on again same Boot Menu with 1), 2) & 0) only as active :(

What to do ?
[Barnes & Noble Nook Tablet] nmyshkin:
At the moment, I have no idea. There may be something wrong with one or more of the files on the card, or the card itself.

Humor me. Download a new copy of https://www.mediafire.com/folder/xjwc1a482a6ll/Nook_Tablet. Extract MLO, uboot-bin, and flashing_boot.img again and copy them over to the SD card once more, overwriting the old copies.

Be sure to eject the card properly from your PC, don't just yank it out. Try it again in the tablet (leave out the power cord for now).

Report.
[Barnes & Noble Nook Tablet] aykov77:
==> Do you mean this file:

https://www.mediafire.com/file/yv2pqev1akl8bfg/succulent_boot.zip/file as attached on the print screen?

==> All done as described, now with or without power cable in Power Button does not start the E-Book, not functional with SD card inside... :( After taking SD card out is booting straight to B&N v.1.4.4 :( same as in the beginning...
[Barnes & Noble Nook Tablet] nmyshkin:
Yes, sorry about the link. I must be losing it.

Well....the card is defective. You have two choices:

1. Reformat the card with your PC and do the whole card-building thing again.

2. Choose a different card and try the whole thing again. Some cards just don't work. Nobody knows why.

There is the chance that some files are corrupt, but I think that is low, unless you frequently have issues with downloaded files being corrupt.

The only other thing I can think of is to make an image of my working card and have you download and burn that to one of your cards. I have no idea if that will even work. Best to try again making your own card.
[Barnes & Noble Nook Tablet] aykov77:
==> I did with 2 different SDcards + one more time with the same one which I used initially. Every time is same with all 3x SD cards...

Again as active are only 1), 2) & 0). "SDC Recovery" is inactive :( I tried with & without power cord, all was done properly... :(

==> Same was with another 2x SD cards :(

==> Never been a problem with downloadings... May be the links are not fresh, or files inside are currupted itself...

==> That sounds good, as long as you advise best program to be used for image creation/burning... What do you think if you send all files in a *.rar/zip file, please refer to attached printscreen if used files are accurate as you described, I think was following properly your instructions.

==> Definitely I need to wake up my sleeping E-Book to spend time again in reading as scrolling the web...

Thank you very much for your kind support, effort and time!!!

I'm waiting for your emergency wake up alarm for this old Nook Book :)
[Barnes & Noble Nook Tablet] nmyshkin:
Your file list looks fine. There must be some issue with the card(s).

I have spent way too much time trying to dust off skills that were never very sharp, creating an image file of a cyanoboot SD card. This worked when I wrote the image to a clean card and then copied on the various recovery and ROM files. So the card image only contains MLO, u-boot.bin and flashing_boot.img.

The problem is that so far I have only been able to get the image size down to 100 MB. This is ridiculous for less than 1KB of files. I just don't know enough about the dd utility. I've been looking stuff up, but so far, nada.

I could upload a 100MB image file but would rather not. It will take me awhile to upload such a file and I'm running out of room on my Mediafire account so....

I'll try again tomorrow and if I can't get the size any smaller I'll just upload the 100 MB file. There is no guarantee this will work for you. If there is some issue with your cards (are they really slow, like class 2?) nothing I do from this end is going to solve the problem.
[Barnes & Noble Nook Tablet] aykov77:
Hi, could you check please all 4 micro SD cards I was in use as a photo here attached. Even the last one 32GB Samsung when I tried to change partition type ID to : 0x0C FAT32 LBA, this card was itself such type, with all I tried same, even with inserting the cards inside of the Nook to do formating by Nook and than changing the type with uploading then all files but even that way no success :(

Even I tried with "flashable_CWM_6.0.4.8_chrmhoffmann" in stead of "flashable_CWM_6.0.4.5_chrmhoffmann", even with "twrp-2.8.6.0-acclaim" in stead of "flashable_CWM_6.0.4.5_chrmhoffmann"... nothing changed, same ... only 1), 2) & 0) remained active...

Do you think all four SD cards are not appropriate? I really need to solve this problem with my Nook and to use CM13.

Do you think if you do an archive file with all files in your micro SD card and I transfer to mine will be ok, why should we go with burning image file...

Another issue is: whance I remove any of the SD card from the Nook, after powering on automatically is loading the original Noor Version 1.4.4, not CM starting mode...

Hope there is some way to use it with CM13, otherwise is not so useful device :(

Thanks you so much for your strong support and resistance!
[Barnes & Noble Nook Tablet] aykov77:
Hi, another attempt with different micro SD card 8 GB, see the attachments, same result... only 1), 2) & 0) remained active... :(

Do you think the problem is still in the SD card? Non one of all 5 is working, could be problem with the files may be??? not sure, only guessing...
