Dummies Guide to Fixing 'My Nook Won't Boot'

First off, I need to address credit where credit is due. All credit goes out to Samuelhalff, Nootered, thecubed, iomonster, Decad3nce and anyone else involved with any of the methods I will mention.
As always, everything in this guide is completely at your own risk, I am not responsible for you messing up your device further nor am I responsible in the event that your Nook Color explodes and kills your cat, grandma, etc.
The Fatal Black Screen:
This is the issue where your Nook "refuses to boot up" usually after running Froyo (or possibly HC) off of your internal memory. This is usually caused by, but is not limited too, formatting your sdcard from within Froyo (or versions of HC prior to the flashable zip).
99.99% of the time, this does not mean your Nook is bricked in any way, what simply happened is your boot partition has become corrupted. For you newbies out there, the boot partition is what allows your Nook Color to turn on. The boot partition contains the instructions for what your Nook Color needs to do in order to start up and run.
The Fix:
Thanks to the guys that developed this neat toy, the Nook is set to boot from the sdcard before booting from the internal memory. What this means is, your nook will first search for a boot partition on the sdcard before searching for a boot partition on your Nook's internal memory. Because of this, we are able to boot and run OS software directly from the SDcard. This is how we will be fixing your "bricked" Nook Color.
First visit this link:

Download either the Rootpack, or the Clockwork Recovery image (1gb).
Next visit this link and download the 1.0.0 or 1.0.1 restore to stock files:
http://forum.xda-developers.com/showthread.php?t=914690
From this link you should also download the very last zip on the page. It is titled-flashable boot repartition zip. or something of the like. If you followed all these steps and still nothing, I would recommend flashing this as it can fix a completely screwed boot partition.
If you wish to instead restore to a pre-rooted 1.1, visit this link:
http://forum.xda-developers.com/showthread.php?t=932145
Once you have the either version of the bootable Clockwork Recovery (Rootpack or normal standard Clockwork Recovery) and a software version you would like to restore to, you must write your clockwork recovery to an sdcard to make it bootable in the Nook.
In order to do this, you must use Win32DiskImager on Windows or the command line on Mac and Linux. Follow theses instructions for writing the file to an sdcard (substitute the Clockwork file in place of Nooter):
http://nookdevs.com/NookColor_Rooting
Once the image is done writing, open up your sdcard on your computer and copy whichever restore to stock zip you choose earlier onto the card.
Now with your Nook Color unplugged from the computer, insert the sdcard and plug the Nook into the computer. Your screen should flash to life. After a short loading screen you will see a menu, using the volume keys, you are able to navigate up and down. Navigate down to the menu item that reads "mounts and storage." Navigate down and press "Format Data" then "Yes." Next do the same thing except format system. Using the power button to go back to a previous menu, return to the "mounts and storage" menu, make sure the sdcard is mounted. (If your sdcard is mounted, you will see the option to 'unmount /sdcard'. If it is not mounted you will see 'mount /sdcard'. In this case you would want to press the 'mount /sdcard' option in order to mount it. Again using the power button as the back button, navigate back to the main menu. You will see a menu item that reads "Install zip from sdcard." Select it. Now select 'choose zip from sdcard.' Now pick the zip you placed on the sdcard earlier. Scroll down to the 'Yes' option and select it. Clockwork Recovery will begin flashing the stock image to your internal memory. After a few minutes, the process should complete and you will see a message that says 'Done. Installation Complete.' From here you should remove your sdcard and navigate back to the main menu. Select the 'Reboot Now' option.
Note: Sometimes after you see the 'Done. Installation Complete.' message, Clockwork will freeze up and you will be unable to navigate back to the main menu in order to reboot. If this is the case do a hard reboot (hold the power button for 15 or so seconds so the screen turns off, then hold the power button again till it turns on).
Congratulations, you've unbricked your bricked Nook Color
TO EVERYONE STILL HAVING PROBLEMS AFTER THIS, YOU MAY/SHOULD FLASH SAMUELHALFF'S REPARTITION ZIP MENTIONED EARLIER. (LOOK UP A FEW LINES, SAME LINK AS THE 1.0.0 AND 1.0.1 RESTORE TO STOCK ZIPS)
UPDATE:
IF YOUR STILL HAVING PROBLEMS, USE THIS LINK TO INSTALL 3.0.1.0 ON INTERNAL EMMC AND THEN BOOT TO IT.
http://forum.xda-developers.com/showthread.php?t=958748
note: to do this, you need to be able to atleast boot to the N screen.
MORE UPDATE:
This link has an updated bootable CWM version on it with ext4 support. Write this to your sdcard, format /system and /data and flash CM7.

So I was doing the 'restore to stock' method earlier today and accidentely reformatted my boot partition is there a fix for this or am I completely hosed now?

Not hosed at all, all you did was format the internal boot partition. When you insert the sdcard and turn the power on, your Nook will find the boot partition on the Clockwork Recovery sd card and boot to that, enabling you to do a full restore.

Well then there may be something more wrong with my nook. I have performed this 3 times and I am still just stuck at a blank black screen.

Are you sure you wrote the image to the sdcard right? Have you plugged in your nook and let it sit for a while? The Nook does have a pretty strange way of running its battery completely dead. What OS were you running before you went to restore to stock?

Hi, thanks for putting this topic up and of course full credit goes to everyone who's been so helpful replying to bricked NC posts.
After 4 days of searching and trying to revive my bricked NC (tried the conventional 8 reboots, power+n methods), I believe I have a unique situation where I:
1) Can't load 128MB/1GB CWR SD ('loading' word appears, then black screen of death appears)
--tested a variation of power + n + up/down arrows (for 2-3mins or more)
--used PC USB / AC to turn device on
--used a Sandisk 256MB/2GB/4GB-CL4 and Transcend 8GB-CL6 uSDs
--used Win7, Ubuntu, EASEUS Partition Master, SD Formatter and another Android device to format the uSDs
--burned the .img using both Win32DiskImager and WinImage
2) Can't load any Froyo/HC SD roms (same results as above)
--same conditions as above
--plus tried every available version of NookieFroyo/HC out there
3) Can't access ADB at any given point. devmgmt.msc does not show any hardware with any VID of 2080. When the NC is powered on by USB, windows detects it and chimes, but that connection disconnects instantly.
Simply put, how it happened was:
OOBE -> BN 1.01 -> Autonooter -> block OTA -> Root + gApps > Rom Mgr'd CWR into eMMC -> HC v4 SD -> gApps -> manual su -> dalingrin's 1.1ghz oc kernel -> reboot success > checking on symlinks -> sudden auto-reboot to stock -> reboot done -> HC loads ok -> blacks out, unable to reboot anymore.
Has anyone else encountered this scenario? In my searches I've not come across anyone with this failure. Is it possible that my CPU has fried due to the OC to 1.1?
P.S. Sam, not able to try your methods as I'm not able to even boot anything from the SD.

I'mm in the same boat (nook) tried everything here as well as a similar guide on androidtablets and nothing. I can't boot at all. No power on, just a black screen. Any help at all would be welcome.

The second link in your original post has a link to it as part of step 5.

It took a couple times of me re-writing the CWR image before I could get it to boot. Now I have it booting into CWR but when I flash the 1.0.1 recovery the nook refuses to boot. Any ideas?
edit: I am removing the micro SD before I reboot
edit 2: sam's repartition boot FTW....I think

How about a dummies guide to the dummies guide for the dummies?
Or, better, WTF! ITS BRICKED!
Already did all the things suggested. Twice. Purchased last Nook Color from Best Buy yesterday, brought it home, charged it to 100%, played with it and ran Auto-Nooter 2.12.25. When I plugged in the cable to boot, it came up with the battery low-wait 15min screen. (Battery was at 100%) Tried again, same thing. Re-flashed Auto-Nooter and tried again, black screen. Nothing. Bricked. What I do get is a black screen with a flash of backlight every 20 seconds or so. Tried to re flash Auto-Nooter and boot, nothing.
Today same story, just wasted 5 hours trying: Auto-Nooter, Clockwork Recovery image, Nookie-Froyo, complete restore-1.0.1.......nothing brings up any life in the nook.
Suggestions? (Ready to return......)

Cant boot to SD
I am running the HC v4 flashed rom and I have tried numerous .img files. It is like it doest see the boot image I just created and boots into Honeycomb everytime? Any thoughts or help please sorry I am a noob.

After spending the better part of four hours trying to solve a fatal error with my reverted-to-stock NC, I ran across the fix for the problem.
First of all, the problem: After diagnosing a bad NC USB cable that was causing USB device mounting issues within Windows, I began to encounter a fatal error modal dialog that stated, "Your NOOKcolor encountered a problem that requires a system restart" at the home screen. No matter what I did in terms of formatting & re-imaging, the message remained. In an effort to fix it, I decided to restore to stock 1.1 using a bootable CWR SD image. After following the instructions to the letter, including formatting /System and /Data after shooting the stock 1.1 image onto the NC, the message persisted. I then attempted to back-rev to 1.01 and 1.0, with similar results.
I suspect that what happened to me was that during the process of diagnosing the USB cable issues, I booted from a uSD card that had AutoNooter 3.0 on it, and interrupted the process mid-stream, thus causing data or partition corruption. I'm not a Nook expert, so I'm not certain of this, but based on my general experience level, that's what it 'felt' like.
How did I finally recover? As a last step to the standard revert-to-stock process, after rebooting from CWR, I used a three-finger salute to reset the device. It was only after I did this that the fatal error disappeared.
Just thought that I'd post this in case anyone has a similar experience and is desperate for something else to try.

[Q] Is my Nook Bricked beyond all hope

I was reading this thread [RECOVERY] Monster RootPack 0.7 / Clockwork Recovery 3.0.0.5 SD (1.1 Compatible!). But, since I am new to this forum I couldn't post there. I hope this is the right place to ask for help.
I upgraded my NC to 1.1.0 successfully. I put Autonooter 3.0.0 on a MicroSD card. With my NC off, I inserted the card and then plugged the NC into my PC. I got a black screen for over 5 minutes. It looked like nothing was happening, so, I disconnected the NC, removed the SD card and tired to turn the NC on. No joy, it won't turn on and won't boot at all. I think my Nook is bricked. Any ideas what went wrong?
I've read some other threads about similar problems. It seems there is a fix to get it back to stock (1.1.0). I hope the Recovery thread I mentioned above is where the answer lies. But, I'm a bit confused and don't want to make any more mistakes. I only have one 4GB SD card at my disposal right now.
My questions are as follows:
1. Is my NC bricked beyond hope of recovery?
2. If I follow the procedures in this post can I get it to boot from the sd card even though it won't turn on at all?
3. What is the difference between the Rootpack and the Clockwork Recovery Image?
4. This is the confusing part. Should I download the RootPack? Or, should I download a bootable Clockwork SD card (128mb, 1gb, 2gb, 4gb, 8gb)
5. Since I only have a 4GB card, what should I choose?
6. Should I opt for 1.0.1, or 1.1.0 where it was still working.
7. Can I get all of this on one 4GB card?
8. Is there anything else I should be weary of before starting this procedure?
If i have posted this in the wrong place, I am sorry. But, I hope someone can clear things up for me. Thanks.

This is the right place to ask general questions.
1. Most certainly not.
2. Yes, using a bootable CWR SD is the way to go.
3. Totally different. The Rootpack is the name given to a package that helps you root your Nook. CWR image is a recovery image. That means you can boot to this recovery utility and apply changes to you NC (like repairing stuff, making backups, etc.).
4. An image will adapt to the drive. If you have a 4GB SD and burn (dd) a 1GB image to it, your SD will suddenly present itself as a 1GB SD. If you format it with the right tool, your SD will be 4GB again. So don't panick, if it says 1GB after burning, it's jut "adapted to the image". You haven't lost any disk space.
5. 1GB would be enough, but you can go up to 4GB image with a 4GB.. It could sometimes be a problem to apply an image which is the exact same size as the drive. I would use th 1GB, which is plenty for what you are going to do.
6. That's up to you. Both should work.
7. Yes.
8. Just read threads exhaustively before attempting anything..
So what you need to do is read threads about this CWR Bootable img to learn how to burn it to your SD.
Then, find the appropriate .zip files to flash (apply) (1.1 recovery and 1.0.1 are available in dev section.
Copy them to root of SD.
Boot with the SD Card and apply zip files from SD.
If your NC should still have problems booting, you can also apply a boot repair zip file, that you will find on my Nook Color restore to stock tread in dev..
Sam

His Rootpack wont work on 1.1.0 You should have seen that in his instructions. It will only block 1.1.0 and fake it. You need to see this thread to fix your nook. It is 100% NOT bricked, just messed up atm. You can fix it tho. Read here:
http://forum.xda-developers.com/showthread.php?t=949699

Thanks for thr quick reponse Sam. I'm at work now, but will be able to use your suggestions later this afternoon\tonight. So, if I get a 1gb CWR image on my 4gb sd card, plus the 1.1.0 zip file and put it in the root of the sd card, the Nook should boot up even though I can't turn it on now? How long typacally will it take to boot up? What should I expect to see?
I will post results after I try the procedure. Thanks again!!

Thanks Thiboi69. I have printed out the instructions from the link you sent and will follow them to the T. I'll post results later.

It will work. I have never heard of a 100%bricked NookColor to date. And I have read 1,000's of posts here over the past 4 months. IT is just your boot partition that is messed up and B&N made it check the sdcard first for a Boot partition, then fall back to eMMC. Thank you B&N !!!

I downloaded all the files, wrote them to my sd card, and put it in the Nook. When I connected the Nook to my pc, I got a messaage the the battery was too low to turn on. So, I took the sd card out, and put the Nook on charge. After a while, it turned on, booted up and when I checked my OS, I found that I had
version 1.1.0. Apparently, my attempt to root with autonooter 3, never got installed, partially or completely. And, my battery probably got to low to turn the nook on. So, I didn't need to use CWR after all. I apologize to all who have tried to help me. But, all replies were good and contained useful info.
Now, my question is: Should I try to use Autonooter 3 again, or is there an easier
(more foolproof) way to root v1.1.0?

I just got a nook last night with the sole intention of hacking it - and did so in a matter of minutes. Autonooter couldnt be easier! When you get to the part of putting the SD card in the nook and connecting it to USB to make it boot, just plug it in and go get a cup of coffee. Don't unplug or touch anything until it boots up by itself. At 1st I thought it wasn't doing anything as I didn't see a clockwork mod screen come up or anything, but just be patient and it'll tell you when it's done. Just make sure it's pretty well charged when you do it - mine was about 80% or so.
Honestly after less than a day of the rooted stock 2.1 Eclair OS, I'm ready to drop a fully customized Froyo or Gingerbread image on this thing. Autonooter it 1st and run it for a few days 1st and see what you think. I'm still learning the ins and outs of tinkering with this thing, but so far it seems much easier than the Epic and Moment I've been beating on. Seems pretty well unbrickable too thanks to the boot to SD 1st option B&N baked into this puppy.

Joe, I would recommend downloading the 1gb rootpack image and a restore to stock file. Make your bootable clockwork recovery image, place the resotre to stock file on the sdcard, turn your nook off, insert the sdcard, power on and flash the file. All this info and more can be found in my thread here:

Thanks for your suggestion Riley, please take a look at my post # 7 above. Seemd my NC
had a low battery. When I charged it, all was ok. It booted up and I was back in 1.1.0.
But, I just now tried autonooter 3.0.0 again. When I pluged thr NC inyo my PC, I got some sort or warning message. I hit cancel and waited a few minutes. The message came up again. It said the device was not recognized. I unplugged, removed the card, and my fully charged NV won't turn on. And, windows explorer can not read the sd card. This is basically what happened yesterday to cause my panic. The sd card had all the files befor I inserted it into the NC. Now, it's unreadable and I can't turn on or boot the NC again.
Is it autonooter 3.0.0, or the card, or the Nook, or me?????

One correction to post # 10. I can read the sd card in windows explorer. But my NC won't turn on.

With sd card out of the Nook, I get a "Welcome to the Found New Hardware Wizzard"
What does this tell anyone about the condition of my Nook?

I am having a problem and don't really know what to do. When I start my NC its stops at the N screen and goes no further. I've tried a lot of the different ways to get it back to stock with no luck. When I try to write CWM to my SD card with win32 it either doesn't have enough room to put the stock file on the zip with it or when I open the SD card it says the card needs to be formatted. The file is a tr.gz or something like that is there a step between that I am missing or just download the CWM and write to SD using win32? I also tried adb with no luck. I am very new to rooting so any super dumbed down instructions would be greatly appreciated.

You can put the rom image to a separate SD card. Just swap it after you boot up from cwr. I did it before for flashing froyo to emmc.

Have you followed the restore-to-stock procedure outlined in this thread?
http://forum.xda-developers.com/showthread.php?t=914690

Just a noobish advise!
After configure everything and become accustomed to some of the NC behaviors this should not matter, but I remember at my first attempts at rooting the NC, using a Win7 PC was much easier than using Win XP or iOS devices. Might fix your 'not recognized' problems, sd card recognition and formatting problems etc.

It has CWM on it. I can get it to recovery but it will not recognize the SD or not mount it and I go to mount it in the menu and it says something like can not mount SD card so I have been trying to do the CWM SD burn but I keep getting the above errors I am on a vista computer so I will try it on my windows 7 one and see how that goes. And the different SD card one I will try that as well after work thank you for the help.

Nook Won't Boot After Formatting SD Card

My Boot will not boot no matter what I do. I encountered this issue after flashing to phiremod v4, which worked beautifully until I decided to free up some storage space on my SD card and format it through the Nook. The next time I tried to boot, I got the dreaded black screen.
I've burned Clockwork Recovery (4gb v .7) onto the SD card and copied the Nook Color V1.1.0_r2 rom (found here http://forum.xda-developers.com/showthread.php?t=932145). From there, I formatted the data, system, and cache, then installed the rom from the SD card. Everything went through smoothly, until I rebooted the Nook (with the SD card out). Nothing happens! The Nook simply will not reboot without the SD card inserted. Even if it boots (with the SD card) it just sends me back to Clockwork Recovery.
I also tried recovering the Nook through ADB (using the steps found here http://mrm3.net/2011/01/24/113/). I install everything, but I cannot locate the ADB device in the device manager. I've even used the .bat file to auto installs ADB, but it is still not found in the device manager.
I've read that it is nearly impossible to brick a Nook, but I'm not sure what else to try. I'm a Android noob, so please bear with me. TIA!

Fairly certain I read about a bug with formatting the SD card on the NC, that it would format the internal memory instead. I would imagine you will need to flash a new image to the internal memory (should be stock image floating around here somewhere).

No worries, you are most likely NOT bricked. There are hundreds of posts about people thinking they bricked their device.
First thing is first, IF YOU READ THE POST IT SPECIFICALLY STATES DO NOT FORMAT THE SDCARD USING THE NOOK AS IT WIPES THE /BOOT
My suggestion to you is do some research on XDA there are PLENTY of posts about "unbricking" your device.
I have only seen 1 nook be bricked, and it was hardly bricked because it could be booted from an SDCard.
Try following the instructions here to return back to the stock OS:

Yeah, I realize that was a big no no. I am unable to perform any of the steps in the link you provided because my nook doesn't even reach the 'Welcome to the future of reading' screen. Also, I can't try method 2 because ADP is not working properly.
I should mention that I also tried samuelhalff's first method to no avail. Any other ideas?

So you CAN boot from an SDCard correct? Only way to boot again is to flash the boot file...

Yes, I can boot (to Clockwork Recovery) if the SD card is inserted and the power cord is inserted and I hold the power button for 10 seconds. If I install a rom from the SD card, doesn't it flash the boot file? If not, how do I flash the boot file?

I know you said you tried Sams method, I would re-read how to flash his boot repartition file found on his froyo on emmc thread

Here's the link to the boot file. I did the same thing not long ago (formatted SD from within CM7) and I fixed it by flashing this file to repartition the boot.
It's the last link in the OP of this thread (repartition-boot-with-stock.zip):

If that doesn't work, he has a couple of restore to stock methods in that thread as well.

YES! This did it! I missed this link somehow. Many thanks to all that helped.

Ok, now I'm stuck on the screen that says "Contains Reader Mobile technology by Adobe Systems Incorporated". Did this happen to you C Dippa? I'm going to try a reset and see if that helps.

Nope...it just booted up, may have taken a little longer.
Any luck with it?

Yeah, I had to do the 8 failed boot attempts to bypass that screen, then re-root. Now, I'm all set! Phiremod is installed again.

Glad to have helped! Happy nooting!

[Q] Nook Color Won't Boot-Been trying stuff

I have a Nook Color that was running the Cyanogenmod nightlies. After shutting it down, it would not boot again.
Since it still boots into recovery, I tried reflashing cyanogenmod, a recovery zipp that was supposed to restore the boot partition, dding boot.img and system.img to the internal memory, a total wipe of every partition, flashing with the latest version of clockwork, along with .7, the stuff mentioned here http://forum.xda-developers.com/showthread.php?t=949699, and flashing "nook color return to stock".
Although all flashes completed successfully, the device still won't boot without the sd card. Is there a method I'm missing?

Been in the same boat myself as well as many others. I found that to get it to boot correctly again do this. Use this link (http://forum.xda-developers.com/showthread.php?t=914690) and downlaod the "Remove CWR" file, you'll also want to download the repartition-boot-with-stock.zip which is the last link in the OP right under the Remove CWR link. Once you download each file copy them to a bootable sdcard. Then pop the bootable card into the nook and power it up to into CWR off the sdcard. After that install the Remove CWR zip first, then follow up by installing the repartition-boot-with-stock.zip. Once all is said and done power the Nook off by holding the power button in. take the sdcard out and then power it on. Odds are it will get stuck again but you should be stuck on the N screen. If so power it off and then put your bootable sdcard back in the device so you can start fresh reinstalling CM7 & gapps.

If you repartition boot, cwr will be removed in the process. No need for the second file..

In theory it should and you are totally right on but I've personally seen it where even after repartitioning the boot it still will not boot correctly for whatever reason. That said personally I've found it just as easy to take the extra step to make sure it gets cleared up as it takes a matter of a couple extra seconds to do it.

Thanks, I'll try that.

Followed instructions exactly, but the thing still won't boot. I must have F'd up my /boot partition pretty badly.
Edit: Wiped every single partition and cache, then flashed, now it works. Thanks guys

I am having this same problem and have a question about the options to fix it. I have CM7 stable on my NC and it worked untill I formatted the SD card and rebooted.. now it just gets stuck at "touch the future of reading" screen.
Is it possible to remove CWM without harming the CM7 install? and still be able to boot to CM7?

need help, nook is all messed up--solved

I use the SD card method to have the nook boot into CM7 and when the SD card is pulled, the nook would be stock to be used by my kids. But I think I messed things up and can't restore. Here is what I have done:
1- I tried to update the stock version to 1.3 manually from B&N website but soon realized I could not. It seems like when in CM7, I had tried to flash CWM recovery (which was not needed and is pretty buggy in SD card method for nook). Now the recovery in emmc appears to be CWM.
2-for some stupid reason when I got into CMM recovery, I formatted boot, system,data and cache (not sure if I did boot also or not). My thinking was to flash a stock image and be fixed. But I am now stuck.
Is there a way to go back to stock on the nook? I am still able to boot into SD card and CM7 nightly. Oh ya, I use Linux Ubuntu not windows. TIA

Sounds like you should get the system back to stock before proceeding any further.
Follow the instruction here: http://www.nookdevs.com/NookColor_UnRooting

The problem is that I get into the CWM recovery and not given the reset option following the options on that page. Any idea?
I think my problem is that I'm not really rooted in true sense since I was running off the SD card. Maybe I shoudl root properly, then unroot?

I did kind of the same thing once. I made an Sd card image with CWM on another sd card -- basically as if you are going to install CM7 to emmc. However, once you get to the point where you would flash Cm7, use the stock zip ROM. It will install that to emmc so it will be back to normal. You should then be good to go.

If you follow the instructions you should be left with an unrooted initialized stock Nook Color. Register your account. Then you can wait for the NC to download the 1.3 update, or side load it. Once that is installed you have an unrooted 1.3 stock system.
From there you can try your CM7 card. Don't forget to remove your SD card at the very beginning since like a PC the NC will try to boot off the SD card if it is present.

when I follow the instruction, I am not given the factory reset option. I am stuck at the n screen. It flashed the read forever but then stuck at the n screen. Do I have to wait longer than 5 minutes?

None of this is mine, I owe it ALL to the threads mentioned below.
So as in many posts on XDA say, it's almost impossible to brick the Nook. What a great device. I had to format my SD card to use it to "un-brick" my nook but it was done. I Mainly used the info here http://forum.xda-developers.com/showthread.php?t=949699
Burnt a bootable CWM image onto my SD card. It took a while doing it with dd in Linux. I'm sure it's the same in Windows or Mac. It took about 20-30 minutes. It also took a while to unzip/extract the img file from the downloaded file. Be patient
Then used the CWM recovery remover file from http://forum.xda-developers.com/showthread.php?t=914690 to remove my CWM recovery and used the 1.0.1 file from same thread to flash the stock image onto the nook.
Once the SD card is ready, just drop those files in the root of the sd card. It should have 4 other files in it to boot into CWM recovery from the sd card and let you use the menus to flash those two zip files. It took a while but it's all in those threads. Thanks to the members. Now lets see if I can go up to 1.3 and then root it again.
you also need to do this
