[Q] My NC lasted all of one day.

Well day one is over and I think I might have the first bricked NC. I used CWR to flash this ROM:
http://forum.xda-developers.com/showthread.php?t=932211
I kept getting a keyboard input error and it never worked correctly. I've been reading nonstop through the forum and now my NC won't turn on.
I look through the thread again, only to find out that it is locked and in red letters it now says "just keep away from the SDcard formatting option in settings." Anyone want to guess what I did before I read that? Yup, I formatted the SD card through settings.
It says to use a certain file to flash boot again but I have no idea how to do that if the thing won't even turn on. Does anyone have any suggestions? I can't post in the thread because it is locked.
MY NOOK IS ALIVE AGAIN!!!!!!!!
Not sure what all I did but it's up and running again. I started with the partition file mentioned in the closed thread. I then did a full restore to 1.0. This then lead me to a boot loop with the grey N screen. From there I re-rooted and it almost loaded. After that I did the power +N button and it reinstalled 1.0 for me. I have since rooted the NC and am leaving it as is until Cyanogen comes out with their ROM.

you made a big mistake by starting off with that flash to emmc rom. You should have started with rooting the original firmware.
Try this to get back to stock.http://forum.xda-developers.com/showthread.php?t=931720
If this doesnt work use my fool proof guide here:

I rooted the NC using Huskermania's video on YouTube. I should have left well enough alone but seeing all the videos of 2.2, I wanted it as well.
Thanks you for the link. I plan to follow every step later in the day, after get some rest and relieve some stress. My only worry is, will the Nook turn on after I pop in the SD card and how long do I hold the power button before I give up?
I'm familiar with rooting and flashing phones, I am currently running CM-6.1 on an Evo and a Hero without any problems. Before that I messed with everything from the PPC-6601 to the TREO 800W.

try this:

maybe it's like the root sd and you just need to let it run without any on screen indicators. you could pm him and see if he can offer any help.
good luck.

So I've read through everything and when I installed the SDK I had issues with my PC and getting the drivers to load. I didn't install them and went straight to flashing it, so no matter which guide I followed the driver install failed.
I'm now on a Mac and I'm installing the SDK. Any advice on how to take me from step #11 and on.? I can't seem to be able to find the Windows button fo some reason.

hi -- assuming you still need help, this CWR bootable SD saved me many times.
download this file (I think you may already have it)
http://dl.dropbox.com/u/2248236/froyo-eMMC-0.2.img
so open terminal in your mac and insert the microSD card into an sdcardreader or adapter. If you want to be extra safe open Disk Utility in the Utilities folder in Applications and erase the SD card.
then in terminal:
$ diskutil list
(figure out which /dev/disk# is the sd card)
$ diskutil unmountDisk /dev/disk#
$ dd if=/path/to/that/img/file/froyo-eMMC-0.2.img of=/dev/disk# bs=1m
(then wait an inordinate amount of time when terminal won't tell you anything and you think it is not doing anything... for it to image the sd card)
when it is done, it will tell you XXXXXX files in 0 files out
remove that SD from your computer and put it back in -- it should show up in finder as "Boot" and check to make sure a "restore to 1.0.1 zip" is on it -- if not, let me know, and I'll link you that file as well. You can just copy over that zip to the newly imaged SD card if it isn't there.
once you've got that SD card imaged with the complete-restore-1.0.1.zip on it as well, make sure your nook is unplugged and powered off -- I assume, just hold down the power button for like 10 seconds just to be safe. Put the microSD into the microSD slot and plug the nook into the computer -- that tells it to boot from SD.
you should enter Clockworkrecovery at which point you need to navigate the program with the vol up vol down power and home buttons (power is back, home is select) and go to the mount option and reformat system, then data, then boot. It always freezes on me after reformatting boot, so just power off and back on and it should return to CWM. Then go through the steps to flash that recovery zip that is on the sd card! Make sure you select "select zip from SD card" and you should be good to go.
good luck.

[Q] I have done the impossible, bricked the color nook

I received the color nook a couple of days ago, got the home wifi connected, registered to B&N, updated to 1.1, rooted it easily with autonooter and added some apps. All good. But I decided I needed to delete some apps, and couldnt do so without a file management system of sorts. So, I followed the directions on this youtube
(I also used this guy's work for the root) and all went according to plan. Until I rebooted and tried to register. I am stuck on the reregister, it spins and spins and goes nowhere. My computer wont recognise it as a nook, let alone a drive so I cant even sideload the update. My wifi is fine. I have rebooted with the 8 times method many many times. Nada.
I did see elsewhere that when unrooting you should unroot first, and then deregister and wipe clean. This is the opposite of what the youtube said to do. I see on the postings that several others have had the same problem but huskermania has not responded. hellpppp

So it's not re-registering? I've never experienced that. You for sure haven't bricked it, as it got that far.
Try this:
1) Download the 128mb bootable CWR. (http://legacyschool.us.to/nookdev/clockwork/cwm_128mb.tar.gz)
(Credit: thecubed)
2) Burn it to a 2GB+ card using Win32DiskImager.
(Disk imager download: http://launchpad.net/win32-image-writer/0.1/0.1/+download/win32diskimager-RELEASE-0.1-r15-win32.zip )
3) Download the stock 1.1.0 firmware here: http://www.barnesandnoble.com/u/nookcolor-support-software-update/379002520/?cds2Pid=35758#2
4) Drag the .zip you downloaded from B&N onto the SD card.
5) Turn off the Nook
6) Insert the SD Card
7) Turn on the Nook. It should boot into recovery automatically.
8) Install from .zip
9) Select the stock 1.1.0 firmware.
After it is done installing, remove the SD from the Nook and reboot. You should now be in stock 1.1.0. (And able to register.)

Oh gosh, after five hours of frustration, this fixed it!
the nook devs came to my rescue, I cant post links yet as I am a newbie!
Thankyou thankyou thankyou!
huskermania, your rooting the nook youtube was brilliant, but I see lots of others had this problem using the unroot youtube. I will post the fixit on that too, I am not allowed to post it here until I am an oldie.

What did they tell you to do? How did you fix it?

Didn't even see that. =P Avoids having to go to 1.0.1 and then updating to 1.1.0

I have been a little stressed by all this, I spent three hours last night trying to fix it, and then another two this morning. The bottom line was doing this:
1. With the NOOKcolor powered off hold down the n button (home) and Power Button until the NOOKcolor powers on.
2. You will be prompted with a Factory Reset dialog.
Press POWER key to Exit
Press HOME key to continue
3. Press n button (home).
4. You will be prompted to confirm.
Press POWER key to Exit
Press HOME key to continue
5. Press n button (home).
6. A Clearing Data dialog will show. NOOKcolor will reboot automatically once complete.
I was thinking that I could use your method woot, and was about to do this when it all came good using the method. I love the root, and will do it again. I have no idea what went wrong for me, and a few others by the looks.
Thankyou once again both of you, and maybe my thread might help others. I had done so many google searches, 8 turn offs, etc etc and nothing would do it for me.

How do you get it to boot from the SD card when the power button isn't doing it? I can push on the power button all day long and nothing at all is happening.
Edit: Never mind, it suddenly decided that it wanted to work. I think I might have a faulty power button.

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:
http://forum.xda-developers.com/showthread.php?t=922870
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?

Sorry. But if the boot partition is corrupt these files wont suffice. You'll need to flash my boot repartiton zip..
Sent from my HTC Desire using XDA App

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.
DS

Anyone know why I would not able to run a ROM?

I have tried SD and EMMC. *I have reset to factory no luck. I was able to run CWR and Auto.nooter.3.0.0
When I start up the SD or EMMC, it gets all the way to the luck screen. The Android system shows on the top and the Sdcard is trying to load, then it says it is safe to remove Sdcard. Then it turns off. The last thing I did was load Phiremod on SD like was posted in [ROM][CM7] size-agnostic sd-card image and CM7 installer SD card, glgehman post #178. Any ideas how to fix this.

If you are trying to run roms off an SD card, good luck. It appears it will only work right with certian sd cards. search the forums for suggestions on cards. I have a few patriot sd card's mostly class 4, and although they booted, the os was unstable and buggy. I eventually just bit the bullet and went with an EMMC Rom. First i tried the dual boot as i was afraid to lose the stock os. that lasted a few days till i realized how awesome cm7 is.
its pretty easy to install. Download one of the CWR 3.0.1.0 SD images. and place it on a small sd card. (one of these will work fine http://forum.xda-developers.com/showpost.php?p=11999569&postcount=4)
Turn on your nook with the SD Card in. It will boot to CWR 3.0.1.0
Download the rom of your choice for me its cm7. (http://mirror.teamdouche.net/?device=encore) Put this on a different sd card (i cant find a way to do it on the same sd card)
once booted remove the bootable sd card, put in the sdcard with cm7/nookie froyo ect. browse threw cwm (volume buttons up and down, N button enter. Power Button back) arrow down to "install zip from SD card." then select "choose zip from sdcard" then select the zip for CM7. then arrow down to yes and it will install, this will take about 5 min.
then go back to main menu, select "wipe data/factory reset" and go to yes.
Go back to main menu, select "wipe cache partition" and select yes
then go back to main menu, select Advanced, then select "wipe dalvik cache" and select yes. This will most likely lock up CWM it will return to the menu but it wont be responsive.
From this point hold the power button until the device is powered off. make sore your cwm sd card is not in your nook, and power it back on. you should see the CM7 Logo.
Once booted into cm7 setup your wireless, your google accounts, ect. put in a clean sd card (the card you used for installing cm7 is fine) launch rom manager, and install cwm 3.0.1.0 to your device (so you wont need to use the bootable sd card any more)
once you install this reboot into cwm from rom manager. Download cwmr_3.0.1.0.zip from http://forum.xda-developers.com/showthread.php?t=971197 and install this zip just like you did cm7. This will upgrade your cwm kernel to the ext4 compatible kernel.
from here your done, you can go back into the rom, or install the below package in CWM
i suggest installing google apps. http://wiki.cyanogenmod.com/index.php?title=Gapps#Google_Apps
installing dalingrin's over clocked kernel http://forum.xda-developers.com/showthread.php?t=925451
and installing the hard key editor http://forum.xda-developers.com/showthread.php?t=965023
Most of this guide is for cm7, but you can modify if you want to do something different. keep in mind this will wipe everything off your device.
when you upgrade to a new cm7 nightly all you have to wipe is dvalik cache, keeping all your settings/apps in tact.
Hope this helps.
Please note im not responsible if you break your device following these steps. These are the steps i followed to install cm7 on a friends nook. You might be able to cut out some steps or condense these steps to get it done faster.

As far as auto nooter and the stock os.. I always felt like i did not know if it was working. follow the steps exactly. when you plug it in to your pc, you should hear your machine recognize it. at that point just let it go. you wont see much. it should eventually boot. then remove the sd card. and you should be rooted.

I have cards that were working, now no ROM works even on the EMMC. I have used these ROMS before with out any problems now I am unable to use them. I can only use Auto-Nooter. The cards (5 of them) are Sandisk all worded before.

can you elaborate on what you mean by not working? what steps are you following? what is it doing/not doing. have you installed cwm to the internal memory? have you updated the kernel?ect it sounds like what you need to do is boot of an cwm sd, and wipe everything and start from scratch. i have not had to do this.

[Guide] Rooting the NC, Installing Custom ROMs, Re-partitioning, etc.

Rooting the NC, Installing Custom ROMs, Re-partitioning, dual-booting, un-bricking, burning SD cards, Theming, etc for the Nook Color!
This guide is aimed to help anyone (from Newbs to old Android veterans) to get their fancy new Nook Color up and running to their liking. Note that most of this was cooked by ROM devs, not me. So go ahead and thank them for it.
Re-partitioning the Blue-dot NC​
You may have purchased a new Nook Color, and looked on the box and said "Huh. I wonder what the blue sticker is there for?" Well, everyone should go check in their boxes right now. The blue-dot Nook Color's give you 5 GB for apps (like anyone could fill that much space up! Normal apps are between 50 KB and 1 MB) and only *gasp* 1 GB for your own data. (Books, Movies, etc). This also messes up everything to do with rooting and flashing ROMs. If you don't have a sticker, you don't need to follow this part of the guide. Skip to rooting. To those who do, to go back to the classic Nook Color partitions, you must flash a package through CWM. Todo this, you will need a microSD card. A cheap 1 GB will work. Once you have the microSD, download this to your computer. Then simply follow these instructions to burn an SD card:
Windows Instructions:
1. Download Win32DiskImager.
2. Insert the microSD card into your computer. You will need a microSD card USB adapter for this. DO NOT USE THE NOOK COLOR FOR THIS! Open up Win32DiskImager for Windows. Then in Win32DiskImager select your sd card. Make sure to have a backup of it as this erases it.
3. Select the file to write and browse for the downloaded CWM image from earlier. Select it and then OK. Hit Write. Once it says it's done, your Done!
Mac Users (If you are on Linux you'll know what these mean on Linux because anyone who runs Linux has a knowledge on computers)
1. Open up Terminal & Disk Utility
2. In Disk Utility, select your sd card on the side pane and then hit Command+I. Somewhere in the popup there should be something like "disk3" or "disk5". If you get "disk5s2" read it as "disk5". Take note of the number, not the "disk" part.
3. Go back to Terminal. Type:
Code:
diskutil unmountDisk /dev/diskX
Replace X with the number you got from earlier.
Then
Code:
sudo dd if=xx of=/dev/rdiskX bs=1m
Replace xx by dragging in the downloaded file into Terminal. replace X with the number from earlier. Here is a sample command:
Code:
sudo dd if=/Users/Steve/Downloads/cwm.img of=/dev/rdisk6 bs=1m
<-- Note that there is no space between the = and the path to the file.
It will then prompt you for a password, the Admin password. Type it in (I'm assuming you know it, if not ask your parents and tell them this is important) Nothing will show that you are typing, to be secure, but it will type. Then hit enter. Wait until until you see the username on the left again. Done!
-For both Windows and Mac users-
Once that is finished, eject the sd card from the computer. Put it in your Nook Color. Turn off and Turn on the Nook Color. You *SHOULD* see a Loading screen. If not try the instructions again. Then you will be greeted with a yellow+black screen. Take the sd card out and hit the home button. It should reboot the Nook. If not, hold the power button until it does. Put the sd card back in your computer. Then download this and put it on the sd card. Put the sd card back in the Nook and then reboot the Nook. Again, loading and then yellow+black screen. This time use the Volume- to move down the menu, and select "Install zip from sd card" Hit the home button there and then select "Choose zip from sd card" using the home button. Find the zip you downloaded and put on the sd card. Select that, then select "yes". It will flash that and then you will be back to the menu. Hit the power button and then select "reboot system". Now you should be ready to get on with the rest of the guide.
Rooting the Nook Color (Stock)​
Everyone want to do whatever they want with the Nook Color. They want to copy files, install Android apps, get a better browser, etc. The only snag is that B&N doesn't let you do that by stripping the Android OS of most of it's features, making it a trivial eBook Reader OS. Well, Mr. Root is here to change that. Now enough of that stuff, let's root your new Nook!
1. You must know the OS version of your Nook Color. Todo that, hit the arrow at the bottom and touch Settings. Go to "Device info" and then select "About Your Nookcolor" Under software version you should see a number. For most, it will be 1.2. If it is anything under that, go ahead and upgrade your Nook using the official B&N method:
The ver1.2.0 update is available over the next week as an automatic download that will roll out to NOOK Color customers connected to Wi-Fi®; or to get the software update right now, follow the instructions above for manual download. (Don't manual update. It's a pain.)
If your NOOK Color is registered and has Wi-Fi® connectivity (Wi-Fi® should be turned ON and connected to a hotspot), your device will be updated over the next week.
The process will take 4-5 minutes for a manual download (depending on your Internet connection). You should NOT turn your NOOK Color off while the new software is being downloaded. Once the software update is completed, your NOOK Color will automatically restart and display the Home screen. The software update will preserve your personal settings, including your registered account information, content, display settings, and Wi-Fi® settings.
Once you have 1.2.0 on your Nook Color, simply follow these steps to burn a CWM sd card:
(Note that if you already have one from re-partitioning the Nook Color you still must repeat these steps.)
1. Get an microSD card for your Nook. This should be a backup sd card to restore the Nook in case of failure. I recommend any cheap 2 GB one. Dependent on your sd size, download the correct image here Use the 1st set of links, not the 1gb image at the bottom. Download that and then follow these instructions to make a CWM sd card:
Windows Instructions:
1. Download Win32DiskImager.
2. Insert the microSD card into your computer. You will need a microSD card USB adapter for this. DO NOT USE THE NOOK COLOR FOR THIS! Open up Win32DiskImager for Windows. Then in Win32DiskImager select your sd card. Make sure to have a backup of it as this erases it.
3. Select the file to write and browse for the downloaded CWM image from earlier. Select it and then OK. Hit Write. Once it says it's done, your Done!
Mac Users (If you are on Linux you'll know what these mean on Linux because anyone who runs Linux has a knowledge on computers)
1. Open up Terminal & Disk Utility
2. In Disk Utility, select your sd card on the side pane and then hit Command+I. Somewhere in the popup there should be something like "disk3" or "disk5". If you get "disk5s2" read it as "disk5". Take note of the number, not the "disk" part.
3. Go back to Terminal. Type:
Code:
diskutil unmountDisk /dev/diskX
Replace X with the number you got from earlier.
Then
Code:
sudo dd if=xx of=/dev/rdiskX bs=1m
Replace xx by dragging in the downloaded file into Terminal. replace X with the number from earlier. Here is a sample command:
Code:
sudo dd if=/Users/Steve/Downloads/cwm.img of=/dev/rdisk6 bs=1m
<-- Note that there is no space between the = and the path to the file.
It will then prompt you for a password, the Admin password. Type it in (I'm assuming you know it, if not ask your parents and tell them this is important) Nothing will show that you are typing, to be secure, but it will type. Then hit enter. Wait until until you see the username on the left again. Done!
-For both Windows and Mac users-
Once that is finished, eject the sd card from the computer. Put it in your Nook Color. Turn off and Turn on the Nook Color. You *SHOULD* see a Loading screen. If not try the instructions again. Then you will be greeted with a yellow+black screen. Take the sd card out and hit the home button. I should reboot the Nook. If not, hold the power button until it does. Put the sd card back in your computer. Then download this zip and put it on the sd card. Put the sd card back in the Nook and then reboot the Nook. Again, loading and then yellow+black screen. This time use the Volume- to move down the menu, and select "Install zip from sd card" Hit the home button there and then select "Choose zip from sd card" using the home button. Find the zip you downloaded and put on the sd card. Select that, then select "yes". It will flash that and then you will be back to the menu. Hit the power button and then select "reboot system". Your finished! The nook will boot and as soon as you unlock you will see a white box with 3 options. Tick the check box at the bottom and hit "Zeam Launcher" Now hit the icon with white dots at the bottom and you should see the root apps+the normal Nook apps. Open up the market and download anything you want to! Because you can!
Installing a Custom ROM​
Well, once your Nook is rooted, you might wanna change the ROM to a better, more Android experience. In this case you will need a CWM sd card. Use the instructions above for rooting but at the when downloading the zip to your sd card download one of the ROM zips below:
CM7 - An Android 2.3 Gingerbread experience with countless optimizations to make it awesome. Highly supported, extremely HQ ROM. Download the latest here.
Phiremod Nook - A custom ROM based off of CM7. Anything that works on CM7 will work here. Pretty awesome, good support. Here.
Nookie Froyo - A Stock Froyo experience with customizations. Old, minimal support, not really used. Umm.. Download.
Nookie Comb - Very old, Honeycomb themed, unused, old. Very old. Download.
Honeycomb SDK Build 10 - Honeycomb, optimized for tabs, but slow and unsupported. Pretty old. I cannot find a download.
Honeycomb SDK Build 11 - Honeycomb, really optimized for tabs, slow, and a pretty unsupported. Download.
MIUI - Awesome in my opinion. REALLY REALLY Optimized for tabs, awesome UI, great, awesome, supported, great, awesome, sweet, should flash it. Download as of the latest version at this time of writing.
For CM7, HC, and the Nookie builds you must download this after flashing the ROM and flash that too. It will get Market.
Dualbooting CM7 and Stock 1.2​
0. Make a CWM sd card using these instructions.
1. Download CM7 to your sd card. I recommend the latest version from here. Also, if you would like to overclock download this. Lastly, if you would like to remap Volume + and - to Menu and Back, download this too. Also, your gonna want (duh) have a copy of Nook Color Stock 1.2. This one is the best in my opinion. Also, if you would like to root Stock 1.2, get this. Now get gapps from here. Almost! Download thishere. And now the multiuboot! Grr... this is tiring... but lasties! Get it here. Put ALL the files you downloaded on your SD Card.
1. Boot into CWM. Go into Backup+Restore and create a backup. Then go into Mounts+Storage and unmount the sd card. Put in an MicroSD reader in your computer. Navigate to /sdcard/clockworkmod/ and find the backup. Copy it to your computer. You can now delete it from the SD Card. Put the SD Card back in the nook. Go into Mounts+Storage and hit "Mount sd card" Now from the same place, wipe system, data, and cache. Now go to the root menu (hit the power button once). Hit "Install zip from sd card" then "Choose zip from sd card" Select prep.dualboot.zip. Then redo the choose zip Select your downloaded 1.2 Zip. It should be called "update_nc_stock_1.2_keepcwm.zip" Flash that. Now wait for it to install. Reboot your Nook. It will boot and will ask you to setup the Nook. Set it up but if you don't have wifi, follow these instructions. After setting up, boot back into CWM using your sd card.
2. Now Choose the zip from sd again, but select ManualNooter. That will take one minute to flash. Reboot again. Make sure your root is setup. To confirm, download an app from the market. Any app.
3. Once that is done, boot back into CWM. Flash the zip "eclair-to-dualboot-0.2.zip" It will duplicate Stock 1.2 to the Second partition. Now go into Mounts+Storage, and wipe system+data+cache. Now choose zip again, but this time pick CM7. Then Choose again, pick GAPPS. Then anything else, like that KeysMod or OC kernel. Now flash Multi-Uboot-0.3.zip. Now reboot without holding anything. It should boot CM7. Reboot, but this time hold the home button. BAM! Stock 1.2. Hope it worked for ya!
To those whom it doesn't work:

So after talking to iKingBlack via PM, I tried it again yesterday. And here is the exact sequence of events in case it helps anyone.
Install removal script for dual boot found in these forums
Install stock 1.2 from the link mentioned in OP
Boot 1.2 and register the device
Sleep 7.5 hours and then chat with iKingBlack
Install manual nooter, then the apk enabler
Boot 1.2 to check root access
(no boot from now on)
Install prep dual boot
Install eclair to dual boot
Format system, data and cache
Install CM7 nightly
Install gapps
Install multi boot
Reboot holding N and check stock works as it used to
Reboot normally, check CM7 works and set it up
Since then I have used both partitions successfully.

Unbricking a "not booting" Nook Color​@RileyGrant has done a great job on this so I will quote him:
RileyGrant said:
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:
http://forum.xda-developers.com/showthread.php?t=922870
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.

Burning a bootable CM7 or custom ROM sd card​
People want to burn an sd card to boot cm7 and then take the sd out to use stock os. This doesn't void the warranty, just don't forget to take the sd card out before running off to B&N.
Here you go:
Download this. Thanks @verygreen for this image. Unpack it into a .img.
Use the instructions for burning an sd card above for rooting the nook color but this time the if= should be this downloaded image. Then download the latest version of CM7. Download the latest here. Put the zip on the sd card. Put the sd card in the Nook. Turn it off then on again. You should see progress installing. Once that is finished, you're done! Reboot and it should boot cm7. To get Market, follow these instructions:
verygreen said:
How to install market and gapps:
After you have booted into the CM7 on SD card for the first time and set up wifi access (important!)
Go to http://wiki.cyanogenmod.com/index.php?title=Latest_Version and at the end there is a table with various google apps versions. Get the one suitable for your cyanogen version (CM7 is the latest for now). The file is named gapps-....zip
shutdown your nook and take the SD card out, insert it into your computer.
Copy the gapps-... file to the SD card on the first partition (titled boot) without changing the file name.
Insert the uSD card back into the NOOK and boot into "Recovery mode" (hold nook N key and then press and hold power until the "Loading..." message appears and then disappears with screen going blank. Release power button, then press it again and hold for ~5 seconds, the bootloader "Loading..." message should be on the screen for three seconds or so before you release power button, keep holding N button until screen blanks again. If the screen went off while you were holding the power key, that means you were holding it for too long).
Alternatively if you do not want to fight the timing, boot normally into Android, then from desktop hold power key until a poweroff menu appears, In the poweroff menu choose "reboot", in the next menu choose "recovery" and press "OK". The nook would reboot straight into recovery.
How to update to a new build:
put the new build you want to try on the first partition. (the name must be update-cm-*.zip or cm_encore_full*.zip or just update-*.zip)
Boot from the SDcard in the recovery mode (see above) and the new snapshot would be installed.
The partition layout would be preserved, filesystems are NOT reformatted, so your data should be safe.
Installing other stuff:
Booting in recovery mode would install all files that are named "update-..." and end with .zip The files would then be deleted! Most of the packages should work, but I only tested a subset and not entire syntax of updater script is implemented. Certainly format and delete are not implemented.

Again thanks to @verygreen for the GAPPS install.
Theming your Nook Color
Many people want to theme it to their liking. There are many different themes, but to get one you must perform a search. Type the theme you want followed by "cm7 theme chooser", because CM7 uses a special kind of theme loader. Once you have downloaded it, you need to put the .APK on your Nook. Pretty easy. First, on the Nook, goto Settings>Applications and tick Allow non Market Installs. On Stock OS, use Nook Color Tools to tick the check box. Then, eject the sd card from the Nook and put it in your computer. Copy the apk to the sd card and put the sd back in the Nook. Download ES Explorer from the market. You can navigate your sd card using it. Find the apk and tap it. Hit install. Now open up the app "Theme Chooser". You should see your theme. Select and apply. Done!
Backing Up and Restoring, Coming Soon!

Please help! I followed the instructions and the last thing you said to do was select "reboot system". I did that and am stuck at a black screen with the Nook "n" in the middle and a tiny message at the bottom of the screen that says: "Contains Reader Mobile technology by Adobe Systems Incorporated."
After about 5 minutes I ejected the SD card and then powered off and repowered back on. I'm still stuck at the same screen.
Did I do something wrong? What do I need to do to fix this?

NM, I solved the problem by rebooting back into CWM, choosing factory reset/restore. Then I could reboot. I then rebooted to CWM and flashed the 1GB partition zip again. Then I pulled the sdcard out before rebooting. This time it booted up okay. I think the repartition happened correctly, but I'm not sure how to tell.

awesome! My gf just got one.. this will help a lot once i start modding it..
couple questions.. if i install a custom rom on it.. how big of a difference is the stock 1.2 experience as an ereader .. compared to just having the nook app on cm7 as the ereader app or something? and how does battery life compare?

Any custom Rom will provide better experience and battery life
