Where to begin...
So I based my install off of this YouTube Video: youtube.com/watch?v=88qRbLLEAPQ and after I got done following everything to the T, I was not able to format /data. I feel this may be my problem. After doing all the steps minus that one I tried to install CM7 and it would boot the second time around in CM7 (Something I read was common). IT would get the the skateboard screen and then it would just stay there with the arrow continuously looping around and around. I let if sit for quite some time before I had to power it off.
I called up my buddy who told me I would more then likely have to install it manually with the Android Developer tools (Or whatever he called it). I did not have those tools so I kept poking around online. I found that sometimes the SD card caused problems so I bought a new 4Gb class 4 card. This was not the issue.
I poked around alittle more in CWR and I accidentally formatted /boot. The unit froze up so I restarted it. It booted into CWR just fine and after trying to wipe the /system, /data (Still not working) and /cache and rebooting, it has now just turned to a black screen that I can't even boot from a card.
Now before I just cash in on my protection plan, What can I do to get this running again? I hate having a paper weight sitting on my desk..
Thank you so much!
tl;dr, Tried to install CM7, can't format /data, tried new card and re installing, accidentally formatted /boot and now it won't boot at all.
Honestly, I can't watch Youtube at work so I am clueless what instructions you are following.
1. What version of your NC? 1.2? 1.1? 1.0?
2. What version of CwMR?
3. You tried to install CM7 in the eMMC or uSD?
I don't know which Nc it is... I just got it 2 weeks ago today.
I do believe that the cwr was 3.0.0.3 or something like that... it was supposedly the newest.
and it was the latest stable version of CM7.
My problem now is that my computer has totally crashed and it won't start in safe mode even. I am fairly sure it has something to do with having the files on my computer.. I just have to get that part figured out, then I can get the rest of it working..
Latest CW is 3.2.0.1 if I recall.
I know when I leave my imaged microsd card in my adapter on the laptop that the laptop won't boot. You don't have the card in an adapter on the system do you?
Also, I assume you are trying to install CM7 to internal memory?
You have to use CWR v. 3.2.0.1. Earlier versions will not wipe/clear everything. Do that and you should be ok....
If it has been around 2 weeks ago, then it most likely be v1.2 which you need CwMR v3.2.0.1, which reportedly fixes the format /data issue.
Give it a try again.
Ok, got the Nook to boot back to the Nook software. Won't get past the loading screen, but atleast it is booting..
I got my computer working finally after booting in Safe mode and deleting all the zip files and images from the computer. So now I am back to a clean slate.
Where do I get CWR 3.2.0.1? And then where do I get the CM7 latest release? I feel like I should be listening to you guys rather then listening to the YouTube video.. It was nice to see things happen on there, But it did not work for me.
Thank you guys SOOO much for having this forum and the "How to fix the black screen" tutorial! I would be lost without it!
I'm stuck on a friend's nook.
I've flashed mine about 100 times no problem.
I've put cyanogen on two other nooks no problem.
I'm doing something wrong with this one I guess.
I have a bootable CWM micro SD and I can boot to it no problem, I'm trying to flash the latest nightly.
What I did up to now was flash the repartition data and reformat data zips.
Then I formated system, data and cache.
Then I flashed cyanogen.
I got it to load cyanogen one time!
But when I rebooted I could never get it to load again.
Since then I have formatted the boot and flashed a few different boot fix files.
I'm stumped.
When I boot it now it goes to the green Cyanogen mod banner, than a second later it says 'loading' under that, then it goes to a black screen. I have to hold the power button down for 15-20 seconds after that to shut it off.
So I have a nook that I can boot to CWM v3.2.0.1 from a micro SD card.
What steps should I take to get this thing working again?
What I did up to now was flash the repartition data and reformat data zips.

That wasn't really necessary with CWR 3.2.0.1. I would say drop a copy of the stock 1.3 ROM on the SD card, boot up and start all over wiping data, system, cache and Davlik and then install the stock .zip. That will get you back to the very beginning. Stock full ROM is here: http://dl.dropbox.com/u/30572895/Nook_Color/update-nc-stock-1.3.zip

Tried that, Now I get 'Read Forever' then a quarter second of the 'N' screen that is Grey then turns a sort of washed out in orange color for a half second, then a message screen that says: 'Install Failed' over a picture of a nook with a red exclamation mark on the screen and 'Please power OFF and back ON again. If you continue to have issues please contact Customer Support or visit www.nookcolor.com/support' Then the device turns itself off.
I had gotten that screen a couple of times leading up to this. Got rid of it by flashing some boot fix files or something.
Something is wrong with the loader or some boot data or something I don't know about.
Can anyone give a step by step on how to take a Nook down to a clean slate then build it back up so I can boot Cyanogen nightly?
I can Boot off a micro SD into Clockwork Recovery.
Those were the steps I took to restore and deregister a Nook recently before returning it for a replacement. However, I never messed with the partitions. Someone familiar with the partition structure will hopefully chime in.
Bump having the same issues. Just started today.
Mine works if I leave it charging, As soon as I unplug it..it turns off.

First tried to install final CM7.1.0 over nightly. Followed instructions here on Opening page Nook Color Android Development thread for this and then tried step-by-step Maurice Mongeon - Nook Color: updated Clockwork Recovery Bootable SD page. I left a similiar comment to this post at his page. Scroll up to see his instructions.
http://mrm3.net/nook-color-how-to-install-cyanogenmod-7-1/#comment-1069
From his site: Everything good from ROM Manager making sure latest CWR 3.2.0.1 until reboot into recovery. Get dark purple-black screen, have to power+n force it into internal CWR 3.2.0.1. Gets through Install from sdcard complete. Mounts and Storage > format /cache > Yes – Format gives me Error Formatting /cache!.
If I try format /system… it hangs. Reboot into CWR again it hangs again at Formatting /system… No way to format system, data, cache from Mounts and Storage to boot into clean new ROM!
I can use – wipe cache partition and – advanced > Wipe Dalvik Cache instead afted installing – update-cm-7.1.0-encore-signed.zip (correct checksum) from sd-card. Everything goes OK except it boots back into CyanogenMod-7-08192011-NIGHTLY-encore.
Restoring previous Nandroid from internal CWR or SD CWR also hangs at restoring /system. What should I do? Can not update or get it back to original 1.3 ROM either? Lockups and errors in Mounts and Storage formats stop me! Tried suggestions in this thread using the boot SD version of ClockworksMod Recovery, none of them seem to work. Anybody have any suggestions as to what to do next?
@ Izord and lschroeder.
If you guys absolutely cannot get it going with CM7, I then suggest trying to get back to the original, stock ROM.
If you had formatted /boot, then I cannot help since I never did mine so I don't know for sure but if not, you should be able to bring the NC back in the original stage.

I can not get to stock ROM either, format/system... hangs and I have to hard reboot.
Question for anybody: Can I use ADB or adbWireless to help get around the format/system... error and install CM7.1.0 or Stock 1.3?
Sorry to resurrect an old thread but this is the only place I've found that describes my problem. I'm experiencing the exact same thing with my Nook Color and followed the exact same suggestions without success.
Was this ever resolved? What finally made it work?
This is exactly what is happening to me. I've already posted my problem to another thread but I thought I would comment here in case this thread finds a resolution.
BTW, my thread is http://forum.xda-developers.com/showthread.php?t=1578127
OK, so I wasn´t paying much attention and instead of formatting the system, I formatted the boot of my Nook. After that my Nook wouldn´t boot into EMMC CM7 nor EMMC CWM.
After creating a bootable sd-card I manage to get the EMMC CWM going but, no matter what ROM I tried, or what I wiped, I can´t boot on CM7.
I tried reading every guide and post that would suggest a solution to my Nook but every time i try to download something that is supposed to work I get a broken link. I even try to go back to stock but I cant find a working link for that either.
Anyway, I dont want to go back to stock. I want to get the CM7 going again.
Can anyone help me here?
I got it working again!!!
So, in a overtime hail mary moment, i got it working again. Thank you, xawen!!
Here is how I did it:
I downloaded the "RecoveryFix_3.0.2.8.zip" file from xawen´s post (http://forum.xda-developers.com/showthread.php?t=958748) and install it with the bootable sd-card CWM I had created.
After that, I removed the sd-card and reboot.
This time the Nook showed the "Touch the future of reading" screen (not the Cyanogen screen) and entered into EMMC CWM. I install the "update-cm-7.2.0-RC1-encore-signed.zip" file and reboot. I didn´t wipe anything this time (because I had wiped everything over and over again so I bother).
After the cyanogen screen everything went black and I waited. It took a while, but then, all of a sudden, that little blue fellow showed up. It had never made me happier!
I hope this can help someone else.
Hello,
I was running one of the CM9 nightlies and decided to try one of eyeballer's with OpenGL, and was able to make the switch without any problems, but after a while wanted to go to a non-openGL build and after flashing it my Nook won't boot past the loading screen.
I have a 1GB card with CMW which I'm able to boot to, I've tried wiping data, format boot and format system and reinstalling one of the builds that had previously worked, but still get stuck on Cyanoboot's loading screen. Even tried going back down to CM7 to see if that helped, but stuck on that loading screen as well.
What am I missing here? I've formatted boot, system, cache, data, everything, but the issue persists.
Any suggestions as to how I can make my Nook come back to live.

Well, for one thing, never format boot.
After trying cm7, you still get cyanoboot? It should have changed to the green cyanogenmod logo. If not then your flashes are not working.

After flashing CM7 I get the green boot screen, but my Nook also gets stuck on that loading screen.
When flashing CM9 I can press the ''N'' button and scroll the available boot methods, but when I choose one I get stuck on loading again.
So on both CMs I'm getting stucked on ''loading'', which started to happen on Monday after going from one of the openGL builds to the latest non-openGL build.

Ok, that means that CWM is putting the boot files on the boot partition since they change CM7 vs CM9.
Which version is your CWM on the SD?
You can't boot to anything, not even emmc recovery? Or you just can't boot to 'normal'? Do you even have emmc recovery installed? If you don't, get the first file on this post and flash it with your CWM card. You may be in a recovery bootloop, without a recovery.

Thank you leapinlar, seems like it was me having an old CWM on my boot card that wasn't helping me, installed the recovery zip and manage to boot into that from cyanoboot's loading screen and reflashed and managed to boot my Nook.
I'm still intrigue as to how this happened, do you think that when switching between openGL and non-openGL the boot partition got corrupted or something? I've been flashing many roms for almost a year and had never had this issue happen to me before.
Thanks a million for taking time to help me, you're a life saver.

It's possible your recovery somehow got corrupted during the flash. If that happens, it does not clear the recovery boot flag and it keeps trying to boot to recovery and it can't because it is corrupted. And it just bootloops forever.
Also, make sure your CWM bootable card is a recent version. If you have a newer nook and an old CWM and you try to clear data, it fails and you have a mess.
Hi, I am totally new at this but I been having a nook color for over a year now and been running CM7 on it for the longest time. Tonight I wanted to put CM9 on and for whatever I did now I just can't seem to get pass the Cyanoboot screen. Doesnt matter what I do it just gives me a blank screen and stays there. What do I gotta do to fix it or get rid of this cyanoboot and back to CWM so i can re flash everything. Any help would be great. Thanks

Try flashing latest CM7 then CM9 over the top. Might want to format Data and wipe caches in between.

Try using my bootable CWM card in my tips thread in my signature. It works fine under ordinary circumstances, but I have been wanting someone to try it to see if it gets you out of that bootloop.
Edit: Just a question out of curiosity. When you finished flashing that new ROM with your CWM, were you able to reboot from CWM normally using the menu choice? Or was there some lockup or something where you had to reboot from CWM by hard powering off?

I believe i had to powering off. I'm sorry but I didnt quite understand what you told me to do with the bootable CWM. I am fairly new to all this flashing ROMS crap. If u can explain it a lil bit better that would be greatly appreciated.

Just follow the directions in the thread to make the card. Then put it in the nook and try booting. If it boots to CWM, just use it to flash like DizzyDen said. And when you exit, use the menu to choose re-boot.
PS, the hard powering off caused the problem. CWM was not able to clear the recovery flag and you ended up in a recovery bootloop. Let me know if my card boots.

Thank YOU for testing my card and proving that gets you out of the recovery bootloop you were in.
You need to take one more step. You need to put a new CWM back on your internal memory so it is there ready for the next time you want to install a ROM. If you go back to my tips thread, there is a link to a new flashable CWM zip (version 5.5.0.4) that can be put on your internal memory. The link is in item B1. Just download that zip file, then boot one more time to my bootable CWM card and install that zip. You should not need my card anymore after that unless you get in a bootloop again.
I've had something similar going on. I believe my nook has been using the EMMC to boot. It was on CM7. I grabbed the latest open GL CM9 because I plan on giving this to my parents. I wanted them to be able to use the TWC TV/DVR app which only works on ICS. I am stuck in a loop where it keeps going to recovery and neither flashing cm9 again nor recovering to an old back up is working. Is the recovery SD card the suggested method for fixing this? I'm not stuck in a loop but I am stuck and having to go into recovery every boot.
For awhile, the N menu gave me both EMMC and SD card boot options. Now it only has EMMC ones.

You could try the new CWM SD. Just make sure when you finish using CWM to exit from that by using the 'reboot' choice in the menu. Do not just hard power off.

So slap the image on a clean SD card and boot up from it. After it's done and I hit reboot, what would I do to get back to CM7 or CM9? I haven't had to do something like this yet. Any time I've had issues, I've been lucky enough to go back to a saved clockwork backup and restore things back to how they should be

First thing I would try is just to exit the new CWM via the menu to see if it gets you out of the bootloop. Retry booting without the SD in. If it will still only boot to recovery, I would again boot to my CWM and flash the new recovery to emmc. Next I would try to restore your old nandroid backup with the new CWM. If none of that works, flash a new CM to emmc with the new CWM.
Nook color running Racks triple boot via micro SD card. Micro SD card is a Sandisk 8GB class 4 card.
Was previously running fine for many months with the 2/2/12 roms. I would run CM7 99% of the time and I would get a random reboot here and there, but otherwise very stable.
A couple days ago, I had a random crash and tried to reboot CM7. I could get passed the boot loader screen, but then would have a continuous boot loop with the blue android symbol.
Thinking something was corrupted with the rom, I booted to recovery and tried flashed the rom along with gapps. Still boot looping.
I booted to CM9, and was able to run. So I downloaded the latest CM7 and CM9 roms for Racks triple boot. Flashed both along with the gapps and CM9 fix. Apparently I got lucky and was able to boot into CM7.... once. Thinking everything was OK, I went on with my life and ran the new CM7 happily.
Now, a few days later, I've tried to reboot and I'm back at the same boot loop with the arrow spiraling around the a blue skateboarding android. Note, in that short time that I was running the newest Racks triple boot CM7 rom, I did not run a backup, so, I'm basically out of luck with recovery via CWM.
I've flashed the 2/2/12 rom as well as the latest rom to see if either would work again. nothing... still boot looping... for hours now.
Any suggestions other than wiping the SD clean and starting with a fresh install?
Thanks all.
~mike
Bump...
Been a bit, no responses yet. Anyone have any ideas?
Thanks,
~mike
I think the fresh install will help since you already tried partial reinstalling the roms.

Nook Color stuck in load screen
I have a nook with CM7 installed on it. was going return my nook to stock to give it to my little sister, but when i went to install the stock stuff back on it got stuck in a loop. It won't boot from an uSD card with clockwork on it and when I tried the 7 hard boot in a row trick, it didn't do anything. Did i really brick the thing? or can it be recovered?

You are in a recovery bootloop with no recovery installed. Go to my tips thread linked in my signature. Read item A8. You need to make and use my special bootable CWM SD (select the 'larger' image). Then if you want to return to stock, read item A15.
