I successfully rooted my Nook Tablet and installed CM 7. However I foolishly applied a zip update that was not compatible and now I'm stuck in a boot loop.
My CWM bootable SD card refuses to work no matter what. I've followed the steps exactly as stated :
1. Using GParted on Ubuntu
2. I selected No-Free space preceding partition while partitioning
3. 50MB
4. FAT 32
5. Boot and LBA flags
6. Copied files
I don't know what to do to to make it work. I've tried all sorts of minor variations in partitioning the card but nothing appears to make the SD card work.
Can someone please help me?
Use Adam Outler's Ubuntu recovery image. He provides step by step instructions on how to unzip the image and transfer it onto the sd card. Have to use linux so if your on a Windows pc, then go grab you a cd or usb bootable copy of Ubuntu. The restoration process takes a while and seems like it hangs in spots but have patience. It takes somewhere around 20 minutes for it to complete but in the end you will be back on stock 1.4.0, safe and sound....Good Luck.
Alright well, I managed to get CWM working. Apparently my SD Card was just fine - I just needed to make sure the NT was plugged into a computer at the same time.
Now my question is : how do I get things working again? I had previously thought that I could simply flash CM 7 again and this would fix the issue, but now I realize that for some reason CWM only read from the 50MB partition from which it booted. Changing the SD card after booting into CWM doesn't work either.
So what do I do? Thanks again..
Nevermind. What I did was pushed the recovery to the internal card so that I didn't need the SD card to boot into recovery. I then reformatted my card and dumped the CM7 zip onto it. Then reflashed CM7. Voila.

Glad to read you got it working.
Just wanted to comment on the above.
You can boot the SD version of cwm then remove the SD card. This is exactly how I installed CM7 That I'm currently running.
It didn't take the first time as cwm didn't read my SD. But after a repartition of the SD csrdz no problems.

I actually tried taking the SD card out, reformatting it and then trying to get it to read but for some reason CWM just doesn't do it. Maybe I should have tried a few more times...

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.

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.

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)?

Ouch...I don't have access to a Windows machine at the moment and so won't be able to debug the issue for a while. If anyone else has had any success / failures on Windows, please confirm by replying in this thread.
Alternatively, I guess you could always reboot your machine into a Linux LiveCD for now...

I tried the Win32 application on Windows 7 X64. Then on Linux Mint 12 KDE using the command line.
Hello, I am new to this forum, but have been reading a lot of the information regarding running CM7 on a Nook Color. Thank you to everyone that has been kind enough to share their knowledge about this.
I am pretty new to the thought of running the Android platform on my Nook. My main goal is to be able to use the Nook Color for more than what the B&N operating system will allow. I would like to be able to use it to take notes in business meetings, using an external keyboard, and maybe have a little more functionality for email.
I am having trouble getting the generic sd card image burned to my micro sd card. I have downloaded the image from verygreen's thread. I have tried using Winimage and Windisk32 to burn the image, and have had limited success. My card is a Sandisk, class 4, 8GB card.
I did get the image burned once, and got the CM7 7.2.0 encore zip file copied, and there was a hangup in the booting process. I believe the error message was incomplete image, or something similar.
I have reformatted the sd card numerous times (using sdformatter), and have tried both imaging programs to try to re-burn the image back to the card, and I get a write successful alert, but I cannot see any files on the card. Windows explorer says that the card is empty, and that thee is only 115MB of storage available, so something is happening.
I thought that maybe the files were hidden, so I copied the CM7 zip file over, and put it in the Nook Color. The NC booted up into the B&N home screen.
As a side note, I would like to be able to, if it is possible, to boot into a menu, and select whether I wanted to boot into the B&N platform, or the Android platform.
Any suggestions that you can provide will be greatly appreciated.
Have a great day.
After succesfully burning and running the img from iamafanof.wordpress jellybean-android-4-3-for-nook-tablet. I decided I wanted to have more control over partition size etc and load a ROM from an SD card instead.
So I followed or at least thought I followed the instructions here. iamafanof.wordpress how-to-guide-bootable-cm7cm9cm10-sdcard-for-nook-tablet. However, I thought I was creating a bootable SD card with the ROM on it, but I installed the ROM on the internal nook memory by mistake. The nook tablet runs CM10 well.
The issue is I intended to be able to switch from CM10 on the SD card to the Nook OS like I could originally with the SD card img I mentioned previously. I cannot get the Nook Tablet 8gb to boot from the SD card. I only get CyanaBoot with the options to boot internet or boot internal recovery. The recovery options does nothing and the internal boot takes me into CM10. The SD options are greyed out. I have tried probably 5 different SD boot images including 2 that I know have worked previously. Also tried 3 different SD cards 2 of which I know worked previously. I am powering completely off and then plugging in USB to turn back on as described through the forum. I have tried using the Nook Recovery and it goes through the steps it looks as if it restoring to original state, but it only restores CM10 to original state.
My question is how to I get my Nook to boot to SD or can I somehow use my working CM10 ROM to get things restored to original NOOK OS. My goal is to wipe the Nook clean and go back to original state and then correctly create a CM10 SD boot card. I am a newbie to the Nook, but feel like I have explored all of the most easy to find options on the this forum to fix this.
I have no idea what you were trying to do and what went wrong (because what you say doesn't make sense).
Anyway... Try using the repart.img to get back to stock.
http://forum.xda-developers.com/showthread.php?t=1663836
Instruction in the link I provided is very detailed. Short version: Downolad the 1.42 recovery, unzip and burn an sd-card with the repart.img you will find in the extracted folder. Boot to that sd-card and a restore process will start. After a while (a few minutes?) a green checkmark hopefully appears. Pop out the card and the Tablet will reboot and finish the process and you're back to stock 1.4.0 or something like that.
Iamafanof has ready-made sd images oc both CM10 and CM10.1. Use one of those. Don't overcomplicate things. Use one of them! (Not that I get why you couldn't stay with the one you were running already... That's kind of what doesnät make sense to me.)

Sorry for not being clear. After I accidentally installed CM10 internally on the nook I can no longer boot from an SD card. I have tried your guide and at least 5 others now. I follow the steps to a T. I have made 3 working SD boot cards for the Nook prior to installing CM10 internally. I understand the process. I have 3 different SD cards and none of which make a bootable SD card. Somehow now that CM10 is installed and the cyanaboot comes up on reboot with the options to boot internal or boot internal recovery. The SD options are greyed out. No matter how many different SD cards I use and boot instructions I follow. It will not read the SD card on boot. It does read it fine once the OS boots. I do not currently have gapps installed. So even If i wanted to keep the internal CM10 install I still need to be able to boot from SD to install gapps.

Instead of rebooting while in CM, have you tried to boot off SD from power-off state and by inserting a powered USB cable?

Yes. That is the method I am using. power down. Insert USB. Nook powers up. Cyanotboot Menu comes up. SD boot options are not available. At this point I am ok with just having CM10 on it, but I really need to get the google apps loaded onto the Nook. It simply will not boot from SD or recognize the SD card during boot. It does recognize from within the android OS and on my Windows machine. It shows Nook as an external device and I can access the SD card that way. It just will not boot from the SD card.
Just confirm: you've tried Succulent's pre-made CM10.x SD image (suc as cm_acclaim_10.2.0-RC0_13OCT2013_HD_SDC_IMG.7z from http://iamafanof.wordpress.com/2013...id-4-3-for-nook-tablet-imgsdc-boot-09aug2013/ -- unpack it with 7-zip then write the image to SD with win32diskimager) and it didn't boot either?
FWIW, you can find some info/pointers on making bootable SDcard from http://forum.xda-developers.com/showpost.php?p=36685310&postcount=1 and http://forum.xda-developers.com/showpost.php?p=37515697&postcount=31.
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
