Issues getting CWM mod to work with Nook Tablet - Barnes & Noble Nook Tablet

Hello all. I am trying to root my Barnes&Noble Nook Tablet (model bntv250a, 8gb, It's the tablet, not a color, hd, etc.). I've tried multiple guides from Indirects to Walters, etc. here on the forum as well as several youtube guides and I can't seem to get clock work rom manager running on the device off of my sd card (micro sd hc I 8gb class 4). So before I tear all the hair out of my scalp I was hoping someone on the forum could give me a hand. Please hurry. I can still use some hair spray and make it into a comb over but I'm slowly losing blood from the lacerations in my skull.
To be more specific the issue occurs after I have formatted the sd card, copied the flash img to it using windows file explorer. When I try to boot it it come to a black screen. When the card is removed it reboots too a screen asking if I want to restore the device to factory settings

See section "Making a Bootable Recovery SDcard" at http://forum.xda-developers.com/nook-tablet/general. If you choose to use a pre-made image you need to use a disk-image writer program such as win32diskimager to write (aka "burn") the .img image file to your SDcard, rather than use windows "copy" command to copy the .img file to the SDcard.

I think this is a consequence of your NT experiencing too many failed boots.

Restore Internal SD Card from zip ROM streak 5

Hello friends, how are you?
I'm from Portugal, and i have one nice strek 5 working great.
But i have another two, that don't boot, it stuck on delll Logo.
i think another my friends try to root or update, and fail.
it don't make any fast boot or streak mod.
so i disassemble to read its sd card.
because i'm using windows, so i install DiskInternalls Linux Reader to have acess to sd card files.
When mounted, its show two volumes, "Linux Ext Volume 1" and "Linux Ext Volume 2"
the firs one have 244 Mbs, and the other one have 1.65Gb
the small one have two folders, lost+found, recovery and a lot of jpeg files in root folder.
the second one, that have 1.65Gb, have a lot od folders and semms a lot of a zipped rom image.
Its possible just decompress and copy to the volume?
Thanks
If you format the card and put it back in the streak, it should set it up automatically. However, you will lose anything on it this way.
Ok. i will try..
but, it don't need to write some data in "boot area" ?
I'm asking that, becouse i download 3 roms, all ziped, but easy to see files, i also download streak mod, and has only one img file, it can't be unzipped..
my firts idea, was copy streak boot files, to card, but i can't acess it..
My assumption, and it is only an assumption, is there is some sort of actual rom memory on the phone that holds the lowest levels of the operating system. Maybe fastboot and the recovery menu, but not recovery itself. The rom actually resides on the internal sd card. When I put in my freshly formatted sd card, I simply rebooted the phone and I don't remember if it was automatic, or I had to confirm it, but the streak partitioned/formatted/whatever the internal sd card itself. I then flashed a recovery and a rom.
Hello.
like you said, i have insert a new sd card, but formated in FAT, i think thats the problem.
I try to load Linux Live CD, and format in ext2/3.
or try to copy rom directly file to sd card.
You think might work?
***EDIT***
I have format the card, and i have inserted into sreak and turn it on..
How much time is preparing the new card ?
and how i know that is ready to reboot?
thanks
I have created an image of my inner SD Card right after a factory reset.
Download Here
I created this using Clonezilla, you should be able to use Clonezilla to restore it. It is an image of the entire sd card. You need to unzip the downloaded file to use it.
Note: I am running DSC_Rom, which is Gingerbread based. I don't think it makes a difference.

Root for Nook Tablet 8GB (w/ Android Market)

[Updated 3/4/12] Add flashable SD card image
[Updated 3/5/12] Update instructions to include tethering
[Updated 4/16/12] Add compatibility warning (as suggested by lavero.burgos) and answers to common questions
Sorry for posting this here -- this is the first time I'm posting on xda-developers and I'm not allowed to post in the dev section.
Root for Nook Tablet 8GB (w/ Android Market)​
So ever since I bought the 8GB Nook Tablet last week I've been checking this forum daily to see whether there's a root method that I could use to sideload apps etc.. But it seems that no current root method for the 8GB tablet existed, and I even came across a video showing that none of the current root methods for the 16GB version works on the 8GB.
So when I saw bauwks's updated 2nduboot that allows booting from an SD card, I started poking around to see if I could use that to root the tablet. While bauwks's kernel and ramdisk cannot boot into the stock Nook userland on the 8GB version (it reboots right after the "READ FOREVER" screen), they do allow me to boot into Android's init process, and that's enough to root the tablet and install Android Market. Basically, what I did was package the files I needed as well as a small installer script into bauwks's boot.img.
The result (root + Android market) is demonstrated in this video.
Compatibility
This method is for rooting the stock firmware version 1.4.2 that is shipped with the Nook Table 8GB when you buy one from B&N. It is not supposed to be used with other ROMs such as CM7, nor the Nook Tablet 16GB.
Included
- Root (su + Superuser.apk)
- Android market
Options
There are two equivalent ways to apply this root method.
1. The first, and easier method is to burn an image to your SD card.
2. The second method is to partition and format your SD card and copy over the files yourself. This latter is more complicated than you think as the SD card must be partitioned and formatted in a very particular (and peculiar) way for it to boot.
Instructions for option 1 - burning a pre-built microSD card image
0. Before you proceed, know that THIS IS EXPERIMENTAL SOFTWARE THAT PROBABLY VOIDS YOUR WARRANTY AND MAY PERMANENTLY OR TEMPORARILY BRICK YOUR TABLET. Even though it worked for me, it may not work for you, and worse, it is quite possible that it could cause your tablet to boot-loop or die. I AM NOT RESPONSIBLE FOR ANY POSSIBLE DAMAGES TO YOUR TABLET / ANYTHING ELSE CAUSED BY THIS METHOD. BY USING IT YOU AGREE TO ASSUME ALL RESPONSIBILITY FOR YOUR ACTIONS.
1. You need a microSD card. The image itself is ~55MB, which means any card above 64MB will work. Backup anything you have on that SD card because THIS WILL ERASE ALL DATA ON YOUR microSD CARD.
2. Download this image. MD5: 1a4f5cb32f09d3003b11aa782fe9566f
3. Burn downloaded image to microSD card. This page explains how to burn an image on Linux, Mac and Windows. Ignore the Nook Color-specific stuff, don't download the Nookie Froyo image, and replace in the instructions the nookie froyo image with the image you've just downloaded. THIS WILL ERASE ALL DATA ON YOUR microSD CARD.
4. Turn off the tablet.
5. Put the microSD card with the burnt image into the tablet.
6. Connect tablet to computer using a USB cable. The tablet should boot up on its own; if not, press the power button to power on.
7. After the initial black screen with the "n" logo, you should see a brown box in the middle of a white screen. (If you do not, your tablet is not booting off the microSD card and you probably did something wrong.) After you hit the "READ FOREVER" screen, WAIT ABOUT TWO MINUTES. Even though nothing changes on the screen, a script is copying over root and Google stuff onto the /system partition.
8. After two minutes, hold down on the power button until the tablet turns off.
9. Take out the microSD card and power on again.
Instructions for option 2 - manual setup
0. Before you proceed, know that THIS IS EXPERIMENTAL SOFTWARE THAT PROBABLY VOIDS YOUR WARRANTY AND MAY PERMANENTLY OR TEMPORARILY BRICK YOUR TABLET. Even though it worked for me, it may not work for you, and worse, it is quite possible that it could cause your tablet to boot-loop or die. I AM NOT RESPONSIBLE FOR ANY POSSIBLE DAMAGES TO YOUR TABLET / ANYTHING ELSE CAUSED BY THIS METHOD. BY USING IT YOU AGREE TO ASSUME ALL RESPONSIBILITY FOR YOUR ACTIONS.
1. Create a 50MB vfat partition with boot and lda flags set, as explained in this video. I followed the instructions on the page referred to by the video at the very beginning.
2. Download this zip file, and extract contents to root of the 50MB microSD card partition.
3. Turn off the tablet.
4. Put the microSD card with the burnt image into the tablet.
5. Connect tablet to computer using a USB cable. The tablet should boot up on its own; if not, press the power button to power on.
6. After the initial black screen with the "n" logo, you should see a brown box in the middle of a white screen. (If you do not, your tablet is not booting off the microSD card and you probably did something wrong.) After you hit the "READ FOREVER" screen, WAIT ABOUT TWO MINUTES. Even though nothing changes on the screen, a script is copying over root and Google stuff onto the /system partition.
7. After two minutes, hold down on the power button until the tablet turns off.
8. Take out the microSD card and power on again.
After Rooting
You will not see any visible difference in the interface when the tablet powers back on, nor will your firmware version change, but you should now be rooted. To launch the Android / Play Market, do the following: "n" -> Search -> hit top-left button on screen -> select "apps" -> type "market" in search bar -> select "Market". For a step-by-step guide on other things you'd probably want to do after you root (e.g., installing 3rd-party .apks, making the "n" button start a custom launcher), check out this thread by RevenantOne.
Common Questions / Problems
Here are some of the common issues people have run into according to this thread. Read this through if you have a question or problem before posting it!
1. Am I rooted? / I did everything correctly, but nothing changed after I reboot!
If you saw a brown box and then the "READ FOREVER" screen, you are already rooted. There will not be any visible differences in the interface / software version. To launch the Android / Play Market, do the following: "n" -> Search -> hit top-left button on screen -> select "apps" -> type "market" in search bar -> select "Market". Check out this thread by RevenantOne for other things you probably want to do after you root.​
2. I don't see the brown box screen; instead the tablet just boots up normally.
There are a number of possibilities:
a. Some people have had better luck combining the files from this method with a root image for the 16GB tablet. Theoretically this could work for everyone, so make sure you do try this one out if your tablet refuses to boot (i.e., you don't see the brown box). Instructions can be found in post #131.
b. Your microSD card may be incompatible. As strange as it may seem, people have posted on this thread that certain microSD cards will simply not work. It appears to be somewhat random which cards work and which don't, so you might have to try out several cards from a different brand or with a different size before you find one that does work.​
3. How to restore the microSD card back to its normal capacity from 50mb?
According to user Ashfire[/B], simply formatting the SD card through the Nook Tablet ("n" -> Settings -> Device Info -> SD Card -> Unmount SD card -> Erase SD card) should suffice to reclaim the normal capacity of your card. Otherwise you can use any disk partitioning tool for your OS to re-partition the card.​
Disclaimer
Again, this is experimental software. That it worked for me does not mean it will work for you, or that it won't brick your tablet. I am not responsible for any possible damages resulting from using this method.

My 8GB NT doesn't boot with your files on my SD.
I have been struggling to get any sort of alternate boot-up working...
I can boot to Cyanoboot (which is useless as I haven't gotten any boot.img to load from it), or... I can get into CWM Recovery with two specific flashing_boot.img and boot.img files.
Nothing else boots properly... the tablet either:
A) Sits there doing nothing with the SD card in the slot
or
B) Boots into Bauwks' Box, and after a couple seconds it reboots.
Your files are (A)... no boot at all.
is it stupid to ask what happens if I just place the extracted file directly onto the nook?

The most likely reason is that you didn't create the boot partition correctly. I had the same symptoms at first, but then I decided to follow the instructions in the linked video to the letter (the instructions are also at omappedia.org/wiki/SD_Configuration), including setting the cylinder count and all that, and I was able to boot everything.
To verify, I just deleted all the partitions on my SD card, formatted it normally using the tablet itself, and copied over the files. The tablet refused to boot; the screen remained black. I re-partition it and format it using the instructions linked above, copy over the files and the tablet boots into the rooting script again.

thanks, seems to work like a charm. couple force closes on twitter for some reason. market accessible, unfortunately the one program i need (HSTOUCH) gets hung up at launch. oh well. progress is good though, great work!
Thank you for posting this, especially your video showing how it looks on the 8GB NT. Where I get lost is at step #1 - the video showing how to create the 50MB vfat partition.
If it weren't for that, which makes my head spin, I'd be more comfortable going for the 8GB NT and tackling this.

Yeah, that bit is quite confusing. To alleviate that I've created a pre-built microSD card image that you can directly burn to your microSD card without having to go through the weird partitioning and formatting. I've updated the original post with the link and instructions.

Used the SD image, and it didn't work. Boots up fine both times, but I have no market.
Edit: After watching your video, should I see the box image when using the image? Because that never showed up.

If you do not see the box, the tablet is not booting from the SD card. Can you elaborate on exactly what you're doing to burn the image to your SD card (i.e., which OS you're using and if OS X or Linux the exact command you're running)?

Unable to boot from CWM SD card after resize - is this normal?

I want to install CM7 internal rom but fail to boot from SD after I increase the card space to full capacity. The screen remains black for 20-30 seconds after plugging the cable. And then it will bypass the CWM and launch directly to rooted OS. However, I cannot place the ROM without resizing the card space.
One more question: is it safe to remove the SD card after the system is booted into CWM mode?
Any advice to install CM7 will be much appreciated
Thanks in advanced.

I had the same issue with a few cwm image files. Finally found the cwm files in zip format. Then I just copied them to the root of a blank SD card. I will try to zip them and upload them somewhere tomorrow. Its nice to have an 8gb cwm card.
Thanks guys. Yes a 8gb CWM image will be useful. Anyway, I just copy the CM7 beta zip file to the device internal memory and get it installed. Despite some technical errors (like google play not working), CM7 runs fine basically.
Ugh. Managed to trash my partitions and spent the most of the night learning a crash course of adb. Got things back to normal now. Will try to find my SD stuff tomorrow! Sorry for the delay!

EDIT! --
Right, so FINALLY got my NT back to proper working order.
I'm pretty sure I downloaded this file FROM these forums, however, a few searches turned up nothing, so I dropboxed them.
Here
Format your SD card, giving yourself the full partition to work with. Then unzip that file, and copy the contents (4 items, 1 folder) to the ROOT of the SD card.
That will make your SD card bootable, and acutomatically load the CWM recovery stuff. From there, you can backup your NT's current config.
Also, RE: your Google Play issue, you need to install the proper Gapps for your ROM,
To do that, click HERE then go down to the bottom of the first post, that's Veronica, and she rocks. I've learned more from her about all this stuff than most anyone else, and we've never talked.
ANYHOW. Go to the bottom of her post, and see her "My XDA FTP" link? Click that ( I didnt want to direct link it without her permission).
In there, you'll see a folder called gapps, navigate to there, and down load the gapps-gb-20110828... zip file. Copy that to your shiny, new CWM recovery SD card, and then boot from it, "install zip from SD card" "choose zip" choose that zip file, install it, and you'll have access to the google play (after market updates automatically) and all the other google features!

[SOLVED] Nook Tablet 8GB SD Recovery 6.x.x

I don't normally do this I just lurk around for my questions but this time I really give up. I have done plenty of work with 16 gb stuff, but never 8 GB nook, trying to install CM 10.2 on a friend's 8GB Tablet, the issue is I cannot seem to find an img for clockworkmod I can just burn to an SD card, lavero.burgos guide requires CWM to already be installed into the internal recovery, but what if I take a clean nook out of the box, are there no CWM images I can burn straight to the SD version 6.x.x and after?
The other method seems to be the one where you create the partitions manually. Which is fine and all, and my device is obviously doing something, but it locks up on the cattonbox and doesn't continue on to CWM. Things I have tried:
1. putting in MLO first after freshly creating 0x0c partition (yes its active) and then the other files for custom SD-recovery
2. replacing the recovery in lavero burgos zip with the cwm_6012.img file, renaming it recovery.img
3. also tried renaming the file instead to boot.img that some guy recommended
4. have tried another sd, rinse, repeat
All the "SD" burnable images are either invalid, or have no partition information. The custom SD method has some sort of issue. I do plug in the cable. The problem isn't getting it to recognize the SD card as a bootable media, the problem is getting to go into CWM, I'm all out of wit, it's been two days man, basically:
HELP?
EDIT: Just tried cwm_6033.img; no dice. These images are supposed to be 8GB Friendly I believe. I don't understand what gives
EDIT 2: Great. I wasted some freaking space on the forum. Sorry guys. Use cwm_6033, rename boot.img, and hold "N" when the trash box comes up. Yay

[Q] nook is bricked, still response to root format

hello guys,
i am a new android user and it is second time for me to root/flash room, my nook tablet was rooted and when i tried to flash cm 10.2, tablet won't boot from sd card, so i press n + power bottom(as someone said it can help tablet go to cwm recovery 6.0) i believe i hold 10-15 second, and i accidentally replease one of the bottom, n or power, i am not sure.. so my nook become as brick. every time i turn it on, it says i need to reboot again, if doesn't work i need to contact to nook customer service.
now, i have used two method so far, ubantu and cwm recovery, they seem not working at all(the tablet won't let me in to cmw v6.x when it was not bricked),and i tried the last one and only one that was use repary.img to recover(which is newest method in 2012,i am not sure if there a way way other than this) repart.img won't unzipped on my computer, my computer is win7 64 bit,the zip said,"unexpected ending of this archive"
what that mean?it means i am only one cannot unzipped the file in that thread.
by the way, i can still go to cwm 5.0 for my root-format sd card, but not the recovery sd card or anything else, HELP!!! it has been whole day!

Hi,
you need a clean copy of the repart.image.

the repart.img sd card has been the most dependable way for me to reset any nook tablet , 8 or 16gb to stock.
I'd say get the latest copy of the img file, and burn it to a CLASS 4 Sandisk card
my experience is higher or lower class cards are often not as good for booting from NOOK tablets
if you erased the /system folder accidentally and di not reinstall an operating system, then the tablet will try to boot into recovery
if you erased the /factory partition accidentally, then even with a good recovery partition, the recovery will fail
