boot loops upon reboot, NC 1.2, MN root - Nook Color Q&A, Help & Troubleshooting

I have a NC 1.2. I am able to root using a CWM 3.0.2.8 Msd card with Manual Nooter no problem. The problem occurs when I shut it off and then reboot. It gets to the part where the words "Nook Color" start scrolling across the screen. "Nook Color" completes one time successfully and when it starts scrolling again, it stops halfway through the first "o" in "Color", and just repeats indefinitely. The only thing I could do is completely reset, eight failed boots. At first I thought it may be an older version of CWM on my Msd card so I made a new one with v. 3.0.2.8 and rooted successfully, but first time I shut it off and rebooted, it happened again. I am thinking only thing to do is never turn it off. Any ideas would be greatly appreciated.

What version MN are you using? You’re not wiping anything when you flash MN, right?

Are you saying that after you flash MN, you remove the SD card, it will fully boot up into the OS, then when you turn off the device and try to turn it back on, it will then not boot up? Or, are you saying that after you flash MN, you remove the SD card, and then the device fails to boot?
It sounds to me like you are wiping the system before you flash MN, but until I get the answers to the above questions, I can’t say for sure. MN is a add on pack for the stock OS, not a full rom, so you don’t wipe before you flash.

I have latest version of MN. I do not wipe anything. I boot into CWM and install MN with a msd card. Upon successful installation of MN, I remove msd card and reboot successfully that one time into a rooted NC. I can use Gmail app, download and install from both Android and Amazon markets. However, if I power down completely and reboot, it loops as explained in my OP.

Are you updating Adobe Flash? You can't directly update Adobe Flash from the Nook Color. The most common issues that will cause a boot loop on a NC after having a fully working device, are installing the wrong kernel, and updating Adobe Flash from the Market. If you updated Adobe Flash, download the attached file, and flash with CWM. The file should delete the old flash player, and install the updated one. This should give you a working device again. If it does work for you, please report back here so others will know what the fix it.

I have updated Flash Player from the Market after rooting. If I remember correctly, I've powered down after rooting and installing numerous apps, including Flash, and rebooted . Maybe that's the culprit. I have not installed a different kernel. I'll go ahead and install the attached zip, with much thanks, but I don't know if I want to power off and reboot, for fear of dreaded boot loop.
Ok, I installed Flash Fix and rebooted, and the same boot loop is occurring. Looks like time to reset and reroot, and for now, never turn it off.

I just realized that I missed a step in the install script for that file, that is why it did not work for you. Yes, adobe flash is your problem. To update Adobe Flash on the nook color, you have to uninstall the old version, and then install the new adobe flash.

For all future references, I have attached the working Adobe Flash fix file. It includes flash version 10.3.186.3, that was released today. It has been tested to work, and you can allow auto-update in the market without future problems.

Ok, thanks, I will reluctantly give this a try when I get home from work.
Edit: Ok, now. I'm trying to uninstall Flash Player and having difficulties. It doesn't show up in the app drawer, so I go to Market to see if there is an uninstall option, but there is only an update option, so I updated, and then uninstalled to see if that would work, but it still showed up in "my apps", in market. I opened up app drawer and selected manage apps and found it, but selecting the uninstall button does nothing. I then tried installing Titanium Backup and after installing, Titanium Backup won't open and doesn't even show up in my app drawer. So, I'm a little stymied now. Unsure what to do next

Titanium Backup is going to be your best bet to do the uninstall process. When you selected update Flash from the market, then went and uninstalled it, you were only uninstalling the update. If TB installed, then it should show up in the app drawer of Zeam launcher. You can go into the market, and select to open it from there. Sometime it will not open on first attempt, because it is trying to ask you to give it root permission. If you still have trouble with it not opening, then uninstall it, and try to install it again. You can also open up the “Superuser” app to make sure that it has not been denied root permission.

TB definitely didn't appear in Zeam app drawer. I'm charging now and give it another shot in a bit.
Edit: Success. I got TB installed. I made a stupid error. I only installed the paid app, not the free also. I got Flash uninstalled and installed your Flash Fix.zip with numerous reboots with no boot loops.

Same here. Big thanks to GMPower! (My first post here, now I can use the Thanks button!)

Total noob question. This is my first time rooting. I got the root to work fine but updated Flash before finding out about the loop. I'm not sure what I'm supposed to do to fix this problem. OP in this thread said he reinstalled MN 4.6.16 via bootable SD with CWM and could get his nook to boot up. I tried that and rebooted but I'm still getting stuck in the loop.
Do I need to wipe my nook before reapplying MN?

Use the zip file in post #7 (in this thread). Drop it onto the same SD card you used to load MN 4.6.16. Put the SD card in and it'll boot to CWM....then flash that zip file the same way you flashed MN. Then, power off the NC, remove the CWM SD card and put in your regular SD and turn the NC back on. That should be it...no more boot loop.

I've got the same issue as the thread started and I downloaded the zip from post 7 and flashed it just like I flashed MN, but it's still boot looping. It gets a bit farther into the "Nook Color" logo but keeps repeating.

Boot Loops NC 1.3

This problem started for me on Rooted 1.3. October 5th, Applied this fix.
Thanks GMPOWER

I figure I will explain my problem in more detail. I am working with my girlfriend's Nook trying to get it rooted. The first time I did she had 1.2 stock and I rooted it successfully. She updated flash not knowing that it would cause a boot loop. I had no idea how to fix it so she set it back to factory settings and procedded to update to 1.3 to see if that would solve the boot loop. I rooted it again and it started boot looping again. I found this thread and the flash fix. I flashed it onto the Nook and it fixed the loop problem.
Well she found out that the marketplace has limited visibility with 1.3 and wanted to go back to 1.2 to have her full visibility back. So she factory reset it again, I rooted it again and it started boot looping again. This time though the fix from post 7 isn't helping. I flash it and then reboot and it loads the "Nook Color" logo once fully and then stops and starts it over again and gets stuck at "Nook Col".
Is there anyone who might be able to help me with what the problem is, or am I gonna have to reset it back to stock, use Titanium Backup to remove flash and then use the zip from post 7? I know that it's not a root problem because I successfully rooted my mom's Nook before my girlfriends and her's is working fine.

Followed your instructions and my problem solved, many thanks!

[Q] Can you help a brother out?

I will post the long version here, mainly because I have nothing better to do.
Here is the situation. I bought a NC about 6 months ago. I rooted it using Auto Nooter. I have no idea what ROM I installed to be honest. I'm very much a novice at this. And I'm quite stupid to boot, I might add. It has worked relatively ok since then. The ROM seemed a bit buggy and I had some initial troubles with constant reboots, in addition to some basic things not working and way bogging the thing down, but in general it was ok. I haven't used it much since unless I was traveling.
Today....I was traveling. Traveling to BFE. As such, I decided to bust out my trusty NC and download a new book while I was waiting for my flight. I did so, and something went a bit haywire. It seems that somehow, without prompting, the device has restored itself to the stock B&N ROM (1.1 maybe?). Yet - the Android OS is still there. For example I can click on my task manager app in the lower left corner of the homescreen and it shows that all of my apps are running and I can even switch to them. But my homescreen is defaulted to the B&N one showing my eBooks and I can't figure out how to get my Android launcher back. I have tried to reboot and it does the Droid boot up but reverts to the same B&N home screen.
I was thinking about trying to update to a new ROM since it had been awhile and I figured there must be something better/more stable out there now - Honeycomb or whatever. I guess this is the kick in the ass that I needed.
So now here I sit in a hotel room in BFE. There are no restaurants open past 9. There are no bars. There IS a Super Wal Mart but I think I'm gonna pass on that.
I figured I would look into this. Where to start? Should I re-set this thing to stock and then just pick a new ROM and re-root? Can I do any of this without having a SD card slot in my laptop - just using a USB cable? Will I lose any eBooks that I downloaded?
I await your sage advice.
rooting actually means gaining super user access to the current android rom. B&N, i believe is Froyo, so you did not install any rom so to speak. you were probably just rooted.
I think the issue is with the launcher and not that it is back to stock. What happens when you long press on the home screen?
If you plan to do anything, you will definitely need an sd card reader.
If you autonootered, then you were running stock, but rooted. With a custom launcher replacing the stock launcher, it sounds like.
At any rate, you were probably hit with the automatic update to B&N 1.2 (which is Android 2.2, iirc.) You almost certainly aren't rooted anymore, but it may allow you to run any apps that you already had downloaded, just from the stock app launcher.
When you get an SD card reader, you can check out Manual Nootering. It's basically the same as the old Auto Nooter, but for B&N 1.2. If you change the rom entirely (install CM7) or just run a different rom from an SD card, you'll avoid having B&N overwrite your root access in the future.
Thanks for the responses. I believe that you are correct. I actually was running 1.0.0. I used auto-nooter to root the thing and had it working with a custom launcher. I don't think it updated to 1.2. In fact I know that it didn't update to 1.2. I am trying to get it to do that right now.
I would like to install a new ROM or root or do something after it updates to 1.2 so that I have access to the Android market. What is my best way to do this? Should I just root again from 1.2? Should I install this CM7?
Can you help me understand the differences? Thanks again.
I could Super Wal Mart tonight for a SD card reader if I'm feeling frisky.
I've got all kinds of problems.
I went to update to 1.2 from 1.0. I removed my SD card and erased and deregistered device. I booted it back up and it thinks it's a phone. I put the 1.2 file in the root drive via USB, as I have read over and over that the thing should recognize the 1.2 file and reboot itself. It's not working. I erased and deregistered again. same deal.
Any advice?
I'd do a full factory reset, then try the update to 1.2 again.
A couple of things about the 1.2 update -- do not unzip the update file or rename it. Just drop it as-is into the nook. And make sure to eject the nook from your computer and unplug it.
Thank you aka. I got it to take. I am now at 1.2. Now back to square 1(.2). Any help on this?

ETA: lol, congratulations! I guess just skip to that link at the end.
I'd agree with akaCat that you should do a factory reset, BUT you can only do that if you still have the stock recovery utility, and it seems possible that you do not. Try to get the NC to reset by interrupting the boot 8 times. If it doesn't work, you may have installed ClockworkMod Recovery on your Nook Color in place of the stock recovery utility. You may have done so while rooting, or later from the ROM Manager app, perhaps even by accident.
Have you attempted to boot to recovery by holding down "n" while you power on the device, and continuing to hold power + n for about six seconds (1-one-thousand, 2-one-thousand, etc), then releasing both? If so, do you get a factory reset dialog (series of yes/no options) or a longer menu including items like "mounting and storage" and "flash zip from sd card?" If you get the longer menu, then that's ClockworkMod Recovery, and neither the 8-failed-boots-reset nor the automatic update are going to work.
If you do have ClockworkMod Recovery, don't do anything yet. Hopefully somewhere on the screen it tells you the version number, in the format 3.0.x.x. Just let us know that version number and power off the NC.
If you still have the stock recovery utility, then do the factory reset, boot into the stock OS, connect USB, drop the update file straight on the Nook (not in any folders), safely remove the NC from your PC, and let it sit. Hopefully it will reboot itself.
If not, the next step is probably going to involve preparing a bootable ClockworkMod SD and manually installing a CWM-compatible version of the update, or of a different ROM. This article may help you wrap your head around the different options: http://quinxy.com/guides/how-to-pick-your-nook-color-operating-system-and-install-options/
ETA: lol, congratulations! I guess just skip to that link at the end.
Thank you, Tao. I seem to be a bit stuck, though.
I'm at 1.2 stock. I was able to reformat and erase my sd card. I went to load the .gz image onto the card (for CM7, per instructions here http://forum.xda-developers.com/showthread.php?t=1000957) and I also loaded the nightly build. Then inserted card into NC and booted. Nothing.
Any idea what I'm doing wrong? Should I unzip either file?
One thing that might/might not matter....when I went to eject the SD card from my PC, I wasn't given that option so I just pulled it.
One more thing.....the instructions at the link above instruct you to "write the image to your SD card" but then go on to say "eject the SD card" and then further "insert the uSD card into your computer"
Huh?? Isn't it all on the same card? Why do I need two different cards? What am I missing?
This blog breaks down the same process a little more step-by-step, with videos: http://www.anamardoll.com/2011/04/ereader-running-cm7-firmware-on-nook.html
You can skip the long preamble down to "Ready? Let's get started."
You do need to unzip the disk image, and write it to the SD using a program like Win32DiskImager or WinImage. It's also definitely a good idea to safely eject the SD card from your PC.
Hi Tao and others. Thanks again for all of your help. I'm almost there!
I followed this Ana chick's directions and I have CM7 booting up. I am now at the stage where I am trying to boot up in recovery mode so I can get the google apps and wifi thing going. I can't get it to work! I am holding down the "n"/home button and then the power button and it keeps booting up with CM7. I've tried it probably 20 times. Any help? Thanks!
Can someone also tell me how to access the book I just purchased and was in the middle of reading? Do I have to go somewhere and re-download?

I should add that though I can get CM7 to boot, I never get "The Power of Reading". It's just kind of a flash.
That's all normal--verygreen had to make a new uboot, which no longer shows "The Power of Reading" and also flies through a recovery boot so fast you could miss it. If gapps didn't install, just make sure the .zip is still in the boot partition and keep trying. I'm pretty sure holding power > reboot > recovery boot works now from within CM7, but I would go into Settings>Accounts and try to sign in to Google before assuming it didn't install.
If the book was a B&N purchase, once you have the market working, just install the Nook app and sign into your account, and you should be able to re-d/l the book, possibly even still synced to where you left off.
Thank you so much Tao and others. Up and running with CM7. Any additional mods I should be messing with?
btw, you can also boot into recovery through rom manager, its easier.

Easier than holding power a sec, poking "Reboot," then "Reboot to Recovery?"
Really, it's about the same either way, depending how handy ROM manager is on your system.

How to avoid the nook boot loop problem before or after Adobe auto-updates

Update 20111117: Updated .zip file to Adobe Flash 11.1 and AIR 3.1.
Update 20111020: Updated .zip file to reinstall Flash and AIR, previous version didn't properly fix AIR.
Steps I used to update Adobe Flash (to version 11.0) and AIR (version 3.0) so it doesn't update automatically and thus get me back into the boot loop cycle (again):
Go to Titanium Backup ( Pro )
You need to uninstall with this since these are system apps
Buy a Pro key and keep it on your SD card root, since this app will save your bacon
Uninstall Adobe AIR and Adobe Flash Player from Titanium Backup
It will warn you that you are uninstalling a system app, that's OK
I think that is why the update through Market isn't working
Open Market, Install Adobe Air (3.1.0.488 as of this post) and Adobe Flash Player (version 11.1 11.1.102.59 as of this post)
Nook seems to be working after several reboots. Also, note that Adobe updated their apps. After following the procedure above, I was able to update via Market without any problems with bootlooping.
Obviously, the above steps only work BEFORE Adobe gets auto-updated and you get in the boot loop cycle. If you are already in the boot loop cycle, download this file (Updated link, should work better this time):
FlashPlayer11.1_AIR3.1_Update_Fix_20111117
and install it using a ClockworkMod Recovery SD card.
Get a ClockworkMod Recovery SD card
http://forum.xda-developers.com/showthread.php?p=11987469
Put the zip from the above post on the SD card
Reboot your Nook with the SD card inserted
Install from Zip, Select zip from SD card, select the flash update
This basically will uninstall flash and air as system apps and install as a user apps. This is based on the zip from GMPOWER which updated flash to 10.3, which worked for some but not others, perhaps because it didn't touch Air:
http://forum.xda-developers.com/showpost.php?p=16526691&postcount=7
Also note, I have been through several cycles of restoring backups, restoring to factory, re-rooting, etc. this last week, so I was getting very annoyed and cautious. I think I was able narrow it down to just the Adobe updates causing my problems. I have been able to update ROM Manager, Superuser, and just about everything else with updates; and besides the Adobe updates, everthing worked, and I don't currently have a boot loop problem.
Note, I didn't update Superuser or ROM Manager until after I applied the above updates to Flash and AIR. After several reboots, my Nook is still working fine.
For those of you who are still having trouble getting your Nook back, and the attached zip doesn't work for you, you can do the following. Using the instructions on this site, I got my Nook back up and running to factory new condition:
http://mrm3.net/nook-color-recover-any-bricked-device/
(Quick method at top, not older methods below; instructions slimmed down from several posts here at XDA, updated for stock 1.2) also here on XDA:
http://forum.xda-developers.com/showthread.php?t=914690 (original restore to stock post)
http://forum.xda-developers.com/showthread.php?t=1050520 (update for stock rom 1.2)
Then, I registered my Nook (again).
At this point, I could have tried to update to 1.3, but my patience was a bit low, so I didn't go for it. If you do, be sure to follow the appropriate ManualNooter instructions here:
http://forum.xda-developers.com/showthread.php?t=1054027
Since I was still on Stock 1.2, I rooted using ManualNooter 4.6.16
(while in CMR, after running ManualNooter, I also applied update-Froyo1.2-dalingrin-OC-emmc-090111.zip, and that seemed to work without a hitch)
Then I reinstalled all the other apps I wanted on my Nook,
=== BUT DID NOT YET UPDATE ADOBE FLASH OR AIR ===
Flashed ClockworkMod Recovery, updated a lot of my apps using Market and Amazon Appstore, restored data and other apps from Titanium Backup,
Then I made a full backup of my Nook using CMR. (still booting normal, running fast and clean)
After confirming my Nook was as I wanted it, and that I had a good backup, I did the steps at the top of this post to update Adobe Flash and AIR.
After confirming that was working, and getting another backup on my SD. I then did the updates to ROM Manager and Superuser. It seemed like those updates happened at the same time as the boot loop, so I was cautious. My Nook is still working well without boot loops as of yet.
Results:
Kernel: Stock 1.2
Rooted with: ManualNooter 4.6.16
Additional Mods:
update-Froyo1.2-dalingrin-OC-emmc-090111.zip,
ClockworkMod Recovery 3.2.0.1,
ROM Manager 4.5.0.1, Titanium Backup 4.5.2,
Adobe Flash 11.1, Adobe AIR 3.1 (uninstalled system app, reinstalled via Market, updated via Market)
[Update Zip] CMR zip to update Flash Player and Air
I updated the original post with a link to the zip to fix the FlashPlayer and Air apps. I had intended to post it here, but since I'm new, I can't link externally in a reply.
Please let me know if there are any problems with the zip and I will get it updated. It worked on my Nook.
I updated the zip file 20111020 to fix a problem with the AIR reinstall.
Wow, thank you so much for this! I wish I had known this on the weekend when I was gong crazy trying to figure out why I was getting bootloops over and over. I can't seem to give you thanks though (probably because I never post, just lurk).
So far I haven't done the uninstall/re-install with TB. I am just making sure my Adobe air and Flash don't update, and when Air did I went into Nook Color Tools and uninstalled the update to set it back to what it was originally. That worked but it is a pain if it keeps happening. I will try the TB to uninsall the programs.
I too did a update on ROM Manager and Superuser (and a binary update), and all is still well. No bootloops. I hold my breath though every time my NC gets to the "color" part until the N appears and it all disolves.
thanks for this!!! this was really getting very frustrating.
Well while I would like to report that the flash fix worked, it didn't. It was already on the boot loop so I installed the update with a flashed SD card and nothing. Still stuck in a boot loop. At this point I am just about ready to give up on this device being a fully functional tablet.
Thanks for this information. My nc is currently in a bootloop and won't load CWR. It shuts off before getting to that point (my bootloop is adobe air related). None of the restore to stock via SD card have worked for me. I'm now looking at ADB options, the post you referenced with the fix has some instructions for that. Did you use the ADB or the SD card instructions? I was actually rooted with CM7 before the bootloop.
Thanks,

I realized that my zip was not working to uninstall and reinstall Air properly. Try the updated zip file in the post.

I used the SD card instructions. Unless you have done something strange to your nook (not sure what), it should always boot from the SD card first, so you should never have problems booting into CMR from an SD card.
If the link in the original post doesn't work for you to get a CMR SD card, try the instructions here:
http://mrm3.net/nook-color-updated-clockwork-recovery-bootable-sd/
If you have a newer Nook, you may need to repartition your Nook's internal memory and use CMR version 3.2.0.1. See details here (this guy just condenses the instructions you can find on various posts on XDA, and tries to keep it up-to-date)
http://mrm3.net/nook-color-how-to-blue-dot-nook-color/
Also note that I updated the zip file in the post to correctly uninstall and reinstall Flash. I re=bootlooped my nook, and after applying the new zip, my nook was working.
Just an update....
I wanted to let U guys know that I had updated Adobe Flash, Air and Super Users and this has worked for me. I also went to double check the versions of both Flash an Air and they are the newest versions!? I still went to uncheck the "Update Automatically" setting in the market for them both just in case for future updates for the time being. Back up and Running! Thanks Again to ALL involved who put contributions to this
This may have worked for me
I tried the updated fix posted here, and the Nook booted properly. Thank you for this fix; I hope it continues to work for me.
I will have to locate the automated back up mentioned here (Titanium), and I will see how this works. I had been leaving my Nook on at all times to avoid the reboot until I turned it off yesterday, forgetting that I did not want to do that.
Awesome post.
So...after all this is said and done and I manage to get a restore image to load and actually boot, now the library doesn't sync and the shop won't load and I get error messages such as " internal error exception executing the command ". It is like the B&N servers are confused. Any ideas about that?
I'm having the boot loop issue and neither the zip nor the 1.2 restore work to get past it. Does anyone have any ideas?
Thanks!!!! You are my new best friend. XD I ended up reflashing several times before I found this post. Followed the instructions and my Nook is happily running Android again without reinstalling (again!). I thank you. My Nook thanks you. And the Angry Birds who would have had to start from scratch thank you.
Thank you! It appears to work now. I've restarted a few times with success!
Took me about an hour to find this thead. I knew there would be an easier fix than starting from scratch. The zip worked on my rooted 1.2
Thanks! Keep up the good work
Thanks! That worked for me.

From my previous searches, it seems the boot loop is usually caused by either an incompatible installation of Adobe flash, or an incompatible kernel (central part of the ROM). Hopefully the OP zip will fix the first, but I'm not sure of another way to fix the second, other than reflashing and rerooting. How far in the reflash/reroot process do you get before it boot loops again?

Hmm, haven't seen that error. I'm not sure whether its related to the same problem. It sounds like you might need to re-register your nook with B&N. I'm not sure if you can do this without restoring to stock. Not much help, sorry.
I can't post a reply to this ([NC][1.2][1.3] ManualNooter 4.6.16) thread yet - Still new to these forums... I was one of the many in that thread who had installed ManualNooter 4.6.16 on Nook Stock 1.3 only to end up with a boot loop.
Wish I had found this thread last week - would have saved me a lot of headaches!
It's okay though - every boot loop is another opportunity to learn something new.
Thanks much for the easy walkthrough and I hope others find their way here too.
Just saw another new update for Flash & Air .. released yesterday I believe. Has anyone try them yet ? Just don't want to was my time getting into a boot loop again by updating it.

Stuck in the CW recovery screen, tried everything.

I searched everywhere, but can't find the same problem as mine. I am stuck in the CW recovery screen, after rebooting times after times.
I have been updating the CM9 nightly for a while, didn't have any problem. But when I tried to flash 02-17 nightly, I messed up and in the middle of the install (flash), I hold the power forcing to reboot. Now, it keeps going loop back to the CW recovery screen every time I tried to reboot.

I tried to reinstall the whole thing with the boot-able sdcard, but didn't work. please help! someone?
I tried to wipe, reformatted the system, data, cash, boot. Still stack at the cw recovery screen. Help...
I love my nook and have a road trip coming up. It will be nice to watch a kid movie to keep the kids entertained.
Had you flashed CmWR into eMMC?
Check the ROM information on /dev/block/mmcblk0p2.... this sounds a LOT like the problem 12paq had...
http://forum.xda-developers.com/showthread.php?t=1495913
@Dizzyden, thanks for the tip.
I did repartition to 1g/5g awhile back. I am not sure where to start. 12paq tried many things, which one was the solution? Your rombackup.zip?
Many thanks....
@votinh
what do you mean? I am not using the N&O apps or OS. Pure CM9, therefore I guess it is flashed in eMMC. If not, please advice.

Finally, with the help from the good people of this forum, I was able to restore back to B&N, and reflash CM9 from there.
Thank to you all.
Yesterday my nook color was working great. Today I turned the screen on and it hung. Now I'm having the above problem with it hanging at clockwork recovery.
I've got CM7.1 stable on there running from emmc.

Install the google drivers for adb... if you are in CWR adb is enabled... just have to get the drivers loaded on your computer.

It may be that your "boot to recovery" flag is set, and if so, it will always boot to that until it is cleared. When the cyanogenmod logo comes up hold the n button until the boot menu comes up. Then choose boot to emmc. If it works, go to ROM Manager and flash a new CWM Recovery to emmc.
Welcome to the nightmare I lived last week. Don't worry I woke up, was able to fully recover and forget the dream ever occurred.
I to tried to reformat to 1gb/5gb and ended up in the same boot loop.. If you are in the same spot I was, your boot partition got wiped out. And you may notice EMMC is gone.
After much searching I came across a file... Looking....Looking...Looking...
..........................Ah yes here it is. Here is what worked for me.
1. Boot to recovery (Should be easy at this point)
2. Format System, Data, and Cache.
3. Install the attached Zip file. (RecoveryFix.zip), this should recreate the Boot partition and fix the EMMC.
4. Reboot to recovery
5. Install favorite Rom or restore from backup.
6. Reboot to test.
Again this is what finally worked for me, and I went through a lot of trial and error to get there. I am guessing at your situation being exactly the same as mine.
PS. Ignore my since of humor if you need to.

Nook wont boot up

Hey, i'm new. Just made this account to get help with my nook. Anyway i'll just tell you all what happened because i don't know much about it.
There's two problems i have with it. 1 - Can't sync my google account and 2 - Can't get past the boot animation, keeps re-booting
BTW just got the nook color second hand yesterday, he said it had Android 2.2? on it, not too sure. He also said he did a factory reset on it, hence me trying to link my google account etc. As of right now, i'm not sure if it is rooted or has a ROM? or anything, i just want it going again.
Problem 1 - It was going fine and I was setting it up with the android start up thingy on the screen, but no matter what I tried I couldn't sync my google account with it to get on the android store. I could go on the internet and gmail etc fine, just nothing that needed a google account synced. I tried the usual fix of signing into YouTube using the gmail account but this still didn't link the device to my google account.
Problem 2 - Just last night when I was reading a book on it, it shut off randomly, I thought thats odd because it was like half battery, so I plugged it in via usb. Now whenever I plug it in to usb. It reboots and reboots and reboots. It shows the touch the future of reading logo, then a grey n, then the screen flashes yellow for a split second. It goes to a screen saying it is installing a new software update, but would cut out part way through and re-start the reboot loop. When i unplug it from the power it shuts off and wont turn on. I tried a factory reset and this started, but when it finished 'clearing data' it cut out and restarted the boot loop. As i'm typing it's next to me continuously re-booting.
Please help!! I'm a noob and need guidance haha.
But seriously thanks to anyone who helps

It could be trying to do a self repair of / rom and failing. Read about that in my tips thread linked in my signature. Look at item A12.

Make yourself a bootable CWM card as in my item A10. Then you can flash whatever you want. A new stock 1.4.3 as I said in A12 or partition repairs as I said in my partition repair thread. Or CM roms. Or the romrestore repair zip. Lots of possibilities.

So I make the CWM card. If i flash the stock 1.4.3 is that how it comes originally? Then can i root it from there, then CM7 etc? And is that all compatible with the 1.1 version? sorry for all the questions. and thanks so much! Any ideas on syncing a google account once i get it going?
Cheers
If you want to run stock, flash the 1.4.3 zip that I linked to. It is B&N's lastest version of stock (newer than 1.1) that I modified so it can be flashed with CWM. Then go to Manual Nooter 5.02.19. That will root you and allow you to install other apps.
Or if you want CM, just flash the version you want followed by the appropriate gapps zip. You do not need to update stock first, just flash away.
It is a good idea when switching types of roms to wipe first. You can flash my format 5,6,7 zip to wipe if you want.
Edit: After rereading your first post, you must get out of your bootloop before you can run anything. Just flashing a new rom may not fix it. If it does, great, but you may need to flash some repair zips first. And if you wipe, that may fix your Google login issues.

Sorry for my noobness but what does flash and wipe mean? Never done this before. I just got an sd card reader thing so i can write things on it with win32 disk imager. So to get out of the boot loop i have to flash? a repair zip? I had a look on the help post of yours, would 'NookColor-emmc-stockrecovery-CWM5504asAlt.zip' work? and do i write the whole zip file on the sd card without extracting anything? then what would i do? just turn it on? sorry once again you're a huge help
The first thing you do is unzip the file cwm-5.5.0.4-bootable_SD.zip. That will give a file about 200MB in size with a .img file name. Use win32diskimager to burn that .img file to your SD. Then that card can be used to copy (flash) things to your internal memory to either fix it or put new roms on it. If you put that card in the nook and boot up from a powered off state, the CWM program should start. You can use that to put new things on your internal memory.
Wipe means to format or erase things. Sometimes it is important to wipe what is already there before you try to put new things on.
Given your description of the problem, I would burn the CWM to SD, copy the zip named romrestore-CWMflashable.zip to the SD with your PC, put the SD in the nook, boot and the CWM menu should come up. Select "install zip from SD" and hit the n button. Then select "choose zip from SD" and hit n. Then scroll to the file you copied and hit n. Confirm the choice and CWM will begin it's thing. Watch for error messages. If it completes successfully, power off and remove the SD and see if it will boot. If it does boot successfully, you just repaired it. If it did not repair it, go to my partition repair thread and try some of those repair zips using the same technique.
If you were successful with the repairs, you can use the CWM SD to flash new roms to internal memory (stock or CM). Don't forget to wipe first if you do. An easy, surefire way to wipe is to flash my format 5-6-7 zip on my tips thread.
FIXED! Thanks so much. Gonna root now and then install cm7 or something haha, thanks again for your patience!

[Q] Eyeballer mostly working, Gapps not working

I installed CM9 Eyeballer the other day on my NC. It pretty much works, but if I go into the web browser or any other factory-installed app, hitting the "N" button takes me back to the factory-installed home screen, and I can't find any way to get back to the Android home screen, short of rebooting the device. Is this normal?
Also, I flashed Gapps using gapps-20120429-ics-signed.zip, and the only Google App that appears is Play Store -- I was able to sign in, but the next screen gave me a "Server Error," and that's all it's done since. I verified the md5sum, and also tried again to install it. No change. Is there some version conflict, or something like that?
Edit: did not install CM9, after all. I now have.
What is the 'factory installed home screen'? You mean stock? That is not possible if you installed CM9 over the top of stock on emmc. Can you explain a little more how you installed it and what you mean.
Well...
I followed the directions as closely as I could: create a recovery chip, copy over the zip file (manualnooter-5.08.20-apps2sd.zip), reboot, install from zip file, install Manual Nooter, flash update-Froyo1.2-dalingrin-OC-emmc-090111.zip, install Gapps, reboot again. As far as I could tell, my results were consistent with the directions, up until the symptoms I described. For example, the splash (smash) screen is right, and the rainbow-y thing, and so on.
This partial success is even more frustrating than a total failure.

Your original post said you installed CM9. You did not. You just rooted your stock rom. You might want to edit the title of the post to 'Manual Nooter installed properly, Gapps not working. Then take that CM9 Eyeballer statement out of the text in the first post and you might get some proper responses from folks.
Sure enough.

Ah... I was under the impression that Eyeballer was a version name of CM9. None of the sets of instructions I read made it clear to me that wasn't the case.
I ended up doing a factory reset, then reinstalling everything. The picture is far rosier now -- it finally looks the way I pictured!
Thanks!

Eyeballer does build a version of CM9. But that has nothing to do with what you did. You ran Manual Nooter, which is a tool to root your stock installation. CM9 is a completely different version of Android than stock is. And when you install CM9, your stock is completely removed and replaced by CM9.
You do not have CM9 installed, you have just rooted your stock rom.
Anyway, I'm glad you got it working.
Edit: I see you modified your original post to say you did later install CM9.
[ROM][NC] Unofficial CM9 Nightly builds - with/without OpenGL
I don't have enough posts in XDA to post in the (goo dot gl/vPJcM) actual ROM thread so I'm hoping someone will see it here.
After installing the CM7 ROM a long time ago. they Nook wasn't able to boot into CWM. I can only access the recovery using a bootable SD card. That may or may not matter.
Yesterday I installed both the 3 SEP OpenGL and 4 SEP versions of Eyeballers CM9 ROM along with GAPPS. In both versions I cannot get bast the Setup Wizard since it "unfortunately Closed" every time I "touch the Android".
I did install the ROM w/o GAPPS as a temporary fix but will need to eventually access the Play Store.
I did notice that CWM still wont boot into recovery and the Cyanoboot won't either. Cyanoboot takes me to what appears to be a stock Nook screen claiming that an install has failed and that I should power on/off or contact customer service.
Does anybody have any suggestions?
Thanks!

You do not have CWM installed on internal memory (emmc). That message you are getting means you still have the stock recovery there. You need to flash a CWM to emmc using your bootable CWM card. Look in my tips thread linked in my signature. Look at item A8 and the subheading 'to fix a corrupted or missing recovery on emmc'.
I don't know how to solve your other problem with gapps, other than to do a factory reset with CWM.
From what I can tell, Eyeballer is mostly drinking.

Success! errr..sort of.
Prior to flashing gapps I was able to reboot into CWM. Thank you so much for your help!
Still having the same issue with setup manager after factory reset and wipe of all cache.
If anyone has a work around or another suggestions for CM9 on the NC I'd much appreciate it.
Thanks again.
