I've spent about 20 hours total trying to unbrick my nook color.
It started when I was (happily) running CM7, but I wanted to have HC preview 4 to use at times, so I decided to dual boot it. I went in to dual boot it, and it had an error. So I flashed the remove dual boot zip to reset it, then I went looking for an answer. I find that it looks like my media partition somehow got corrupt, so I go into ADB to see if I can get that working. From within adb I run "adb reboot recovery", and then it never turned on. Freaking out, I searched for an answer. I got it booting into CWM on SD, and Nookie Froyo SD. I've tried all the unbricking methods, even the advanced one that requires DDing boot.img and system.img. I got into adb from recovery and found that my partition table - I had none. So I find out how to fix that, and I do. Fixed it properly infact, looked exactly like it should. So then I go and DD boot.img and system.img, remove the SD, unplug from power, and try to boot into recovery, no luck. Tried a normal boot, no luck. I've done this multiple times. I think it has something to do with the boot partition, I verified it had contained the proper files(u-boot.bin, uImage, etc.), it was marked as bootable, but it wasn't booting.
I held down the power button for 25 minutes just to confirm without a doubt it wasn't(I watched a show while waiting, unfortunately it was my figure holding it down, not tape).
Nothing I tried fixed it.
I think I may have been one of the first to "actually" brick my nook.
Any tips on what I can do to try to unbrick it? Ask me questions, have me acquire data, I don't care.
I have access to adb in recovery, and adb connected wirelessly via nookie froyo sd bootable(for some reason it won't let me use adb via usb).
I apologize if this is in the wrong section.
Also, before you go saying that this is pretty much a repost of other threads, I looked at multiple threads with people trying to fix their nook, threads with 60 pages, read all of them. No one had a problem like mine.
If you are willing to put CM7 on the internal memory, follow the instructions here: http://mrm3.net/nook-color-how-to-install-cyanogenmod-nightlies/
Make your you use the latest version of CWR (v3.2.0.1) Once you have everything working properly, reformat the card to use as storage. Better, keep it as is in case you ever have to preform a new installation and buy a new card for storage. You will need one to properly use CM7 to full advantage.

I was hoping doing what you said would work - but it didn't.
I follow this guide(http://mrm3.net/nook-color-how-to-blue-dot-nook-color/) to get the partitions reformatted properly then installed it.
Glad the site still was able to help you with your issue....
It didn't help. I already followed that guide. Their is one like it here.

Since you said "trying to unbrick" then why not try to reverse back to the original state before installing/running any other ROMs

Go to my youtube page.
Download my ROM by clicking more on my description.
Extract and burn to a SD card with WinImage or something.
Seems like you need to fix your boot partition. Hold the power button down for 15 seconds with no USB plug in the nook. Put your recovery SD in the nook and hold power for 5 seconds you should boot to the SD card. Flash the “repartition-boot_emmc-800mhz-stock.zip” if you want the 800 MHz stock kernel and reboot the nook. If you want the 1.1 GHz Kernel flashed then use “repartition-boot_emmc-1.1ghz-froyo_setboot.zip”.
Once you flash that go ahead and flash my rom just for ****s and giggles to see if you can boot into it. Enjoy. Let me know if I helped.
If this doesnt work you can always DD your way to a new partition. Example below but lets do what I put up top first.
dd if=/dev/block/mmcblk0p1 of=/sdcard/xe.nook.color-froyo-v2.2-boot.img
dd if=/dev/block/mmcblk0p6 of=/sdcard/xe.nook.color-froyo-v2.2-data.img
dd if=/dev/block/mmcblk0p5 of=/sdcard/xe.nook.color-froyo-v2.2-system.img
Well, I'm already processing a return... But if I run across this problem on my new nook, I'll try that.

Return it and try CM7 normally installed to EMMC. Dont **** around with dual boots and all this other crap
When you get your new one in, and if you decide to put CM7 on EMMC, just leave it as CM7 alone.
Shame you sent it back before we could work it out, I was looking forward to trying to fix this - but I can imagine just how frustrated you have been with it and I don't blame you. Probably at the end of your rope and in your place, if I could have gotten B&N to exchange it, I would have too.
Because the Nook Color boots from the SD first, you can always just install whatever else you want to play with to a MicroSD card and run it that way.
Verygreens sd card prep thread is a fantastic first step in this regard. (click "SD Install" in my sig to get to it)
I personally still have my Nook Color stock on EMMC (with B&N official updates) and run my CM7 and other installs from the sdcard. Just make sure it is a SanDisk card and you'll be good to go. (also links in my sig to find out why SanDisk if you're curious)
The benefit to running from the sd-install, especially on possibly unstable ROMS, is that if it doesn't work you simply remove the card to get your device back - instead of having to run recovery on your device.
The latest stable release of CM7 is absolutely fantastic on the Nook Color, and i'd highly recommend it as your daily driver.

I wanted something on the emmc, and my microsd card is to slow to consider booting from it. I'll probably get a better one or just use my current one, and install honeycomb on that.

I had CM7 as my normal install, I just wanted to try honeycomb and my sd card was to slow to consider booting from it.
There's an image around these forums somewhere that lets you dual-boot Phiremod and HC preview on the SD (you just flash it to the SD and go).
It's always safer to play with SD new boots, since you won't hurt your EMMC installs.
With that really said -- the HC previews on the NC are ... not really worth playing. There's no hardware acceleration - so that are abysmally slow. Really bad. You'll try swiping the home screen and go "ugh, back to CM7".
Quite honestly, there's nothing better for us than CM7 on SD or EMMC. Phiremod is just candycoating on CM7 anyhow - and nobody's ever come up with a ROM for us that isn't just fiddling around with a base CM7 or a themed layer on top of it.
What we get from our CM7-Encore installs is pretty much what we want. Theme it all you like - but in reality, nothing else beats it.

...what are your thoughts on making the sd cards with my linux(mint 14) laptop ...am I grasping for straws??
ok so after 3 days of trying, i keep getting stuck on a boot-loop I am asking for some help.
before I begin, I have successfully rooted and installed cm7 on 2 nooks that came factory 1.2,I have searched google and these forums but can't find anything with my specific needs.
I have followed the directions on this thread to a tee:
http://forum.xda-developers.com/showthread.php?t=1054027
i am using a bootable cwm card (2GB) (cwm version 3.0.2.8)
after installing ManualNooter-4-5-18.zip then ManualNooter-4-6-16.zip I remove the sd card and reboot and I get a boot-loop with the "n color" screen animation. It has not booted successfully yet.
I have already used the 8 failed boots method to restore to factory and re-registered the nook.
Then I redid everything again and im back at the boot-loop.
any ideas
i do not have an answer but this answers my question of whether I want to run manual nooter on my 1.3 or try cm7. the cm7 steps seems more intimidating
Well i tried several more times last night with no luck. Then i got brave and just wiped everything (data,system,cache,dalvick) then flashed cm7 and gapps straight from my cwm boot card. I somehow
Ended up with a fully functional nook. App market works. Rebooted several times to be sure. I even tried usb host with my homemade adapter. Mouse, keyboard, and sandisk cruzer all work splendidly thru a powered hub.
My only mistake was i cant find my backup of stock 1.3 rom. Is there one floating around?
Sent from my LG-VM670 using Tapatalk
If I'm understanding correctly, you're trying to go from CM to 1.3, correct?
From what you've described, I suspect Clockworkmod 3.0.2.8 is your problem. If you look carefully as you format /data in preparation for reloading the BN 1.3 firmware, I think you'll see that the format is actually failing. That version of CWM doesn't handle the partitions correctly.
You want 3.2.0.1. See the edits at the top of this thread: http://forum.xda-developers.com/showthread.php?t=987735
If you're already on CM7.1, you probably have the correct version of CWM installed. You can save yourself a step by formatting the /data and /system partitions using that, then continuing on with the rest of the procedure for restoring BN 1.3. I went through all this myself a few days ago while preparing to go to BN 1.4.1.
I forgot to mention in my last post that i realized i was using the wrong cwm image and i burned another card with cwm 3.2.01.
I was still getting a boot-loop so i wiped everything and went straight to cm7.

I didn't read your post correctly.
I had a stock nook that i want to install cm7 on. Not the other way around. I asked about a stock 1.3 file just in case i need to do a restore. The nook is done. Its running cm7 just fine and i have given it back to my friend.
I really need to get myself one :-(
I usually mess around with my sons but he's at his mothers for the weekend with it. After christmas im getting one. Dont know if it'll be a color or a nook tablet but im getting one for sure!
Sent from my LG-VM670 using Tapatalk
If you intended to install CM7 from beginning, then why you wasted time messing around with ManualNooter?
Im still rather new to working on nooks. I thought that it was required to use manual nooter first. Im still not sure.
Can someone clarify for mr. If i just bought a nook and i want cm7 on it, whats the best procedure?

The only boot loop issue I'm aware of is related to Adobe AIR and Flash. The fix is to uninstall them and then reinstall from Market.

I hope you do use Windows at some points.
Let's put it this way.
You bought a PC with Windows XP pre-installed, get home, you don't want XP, so you install Windows 7 on the PC. You just whack the XP.
Same theory applied here, B&N shipped their NC out with the original stock ROM, which is Froyo-based OS. You want to install CM7, which is Gingerbread-OS ROM. You just whack the stock and install CM7.
oh I get it know. so its pretty easy if you want to go straight to cm7 just wipe and flash.
After reading some posts from the nook tablet section, i guess i'm getting a nook color.
what a shame about the locked bootloader :-(
i didnt technically solve the boot loop issue, i just erased everything, but should I mark this as solved and if so how?
The current Nook Color bootloader is not locked. The Nook Tablet's is. I wouldn't necessarily rule anything out, though. The bootloader on the Motorola Droid 2 is also locked, and there's quite an active Cyanogenmod community around it. The only problem is that we're stuck with whatever kernels B&N release, so ICS may be a long way off. I suspect the NC will remain the tuner's machine of choice, but the performance on the NT is very nice. If you can live with a rooted B&N ROM, it's a nice device for now.

No, it seems that some 1.3 based NC units will bootloop if 4.6.16 is used to root them. I'm not sure why. Even after repartitioning to original nook partition sizes, or using CWM 3.2.01 (which supports the new partitioning), it'll still bootloop if 4.6.16 is used. Might be because of the different kernal included, but I'm not knowledgeable enough to know for sure. They root fine with 4.5.18. Haven't tried one with the new 1.4.1 compatible nooters.
To the original poster;
I'm having the same problem here, installed 4.15 successfully, installed 4.16 and am getting stuck in boot loop at the rainbow nook color screen.
I'm not understanding the 8 boot fail procedure though. Is this when you let the boot loop run through 8 times or when you get to the point of when the boot loop starts, shut the NC off and power it back on?
Also, to install cm7, all you did was put it on your sd card, and installed it through cwm?
The 8 boot method if i recall correctly is when you boot the nook and wait until the splash screen shows up immediately hold the power button and shut it down. Repeat 7 more times. If you did it correctly it should take over and do a restore on its own.
If you want to go straight to CM7 I dont think you need to go thru with this procedure because if you create a bootable cm7 card and insert it in your nook while its off then power up, it should boot you into cwm recovery. Once in the recovery you can flash cm7.

Thank you good sir! I was stuck in boot loop forever and couldn't find a clean explanation of the 8 boot fail process. I always tried to turn it off when the rainbow nook color screen came up.
I got it reset, made a flashable CWM SD card with 3.2 and then flashed CM7 on there and it works great!!
That was very frustrating, thank you!
Dont mention it, Glad to here I was able to help you out. I felt the same way when I was in that situation. Lots of googling to get a clearer idea on what that 8 boot method entailed. CM7 really makes it feel like a totally different device.
To all the devs that work on these projects, thank you

Hi all,
I just had a question about upgrading to CM 7.2RC. I am currently running the stable version of CM 7.1. It has been awhile since I changed out the rom. Did I have to do a full wipe of the device before upgrading to the RC? Or can I just wipe the cache and install the update so it maintains everything else on the device.
Any help on this would be appreciated. Thanks.

Just do the second thing. No full wipe.
This thread down in the cyanogenMod forums shows you how to upgrade if you did not know how or want to gleam more information on this. Or for anyone else that is interested. http://forum.cyanogenmod.com/topic/40698-installing-nightly-builds-and-new-71/
Ok, but what do I do if I'm running off a bootable SD card? I was told to just copy the new rom to my F boot, then boot into recovery. I have done this over and over again with no success. I'm sure I'm doing something wrong. if I'm supposed to copy the rom to a specific partition, then Im screwed because I don't know how to do that.lol. By the way, till about 3 months ago I could count on one hand how many times I'd sat down at a computer. Got a nook color as a gift
,and have been in love ever since. I'm running cm7.1 stable, at 1200mhz. I've had to teach myself every step, every step of the way. So if I sound like a idiot, its because I know nothing about computers, but I am learning. Thank you for your patients

You are probably not renaming the zip to begin with update-. You must do that before the installation script will recognize it.

Yes I have renamed it. it was cm-7.2 and I changed it to update-cm-7.2 but still nothing. here's the thing, when I try to format this card on my PC, its saying its write protected, and to switch it off. I assume it means the lock switch on the sd card adapter. If thats the case, something is screwed up, because its not locked. I don't think its my adapter cause its not saying that with other cards. When I copy the cm7.2 it says its copying just fine and I can see it on the card but if I take it out and put it back in, its not there. Sorry for the pain in the butt question, and thank you for your time.

I had the same thing happen to one of my sdcards. I could not format it, or write things to it. I could read it fine, just not change anything. I tried all kinds of readers and software (formatters, partitioners, etc.) It would look like it wrote to it, but take it out of PC and put it back, it was not there. I finally had to throw it away and get a new one. This all happened on my phone, not my nook.
I have followed every SD boot guide on this forum, and watched countless videos on how to do this.
I download the generic and/or CWM IMG, I burn the IMG to a class 4 SanDisk SD card. I copy over the ROM and GAPPS zips. Put it in the powered down Nook and fire it up. Nothing. Not a god damned thing.
I need someone to explain it to me like i'm 5 cause I am clearly not capable of getting this to work. What really pisses me off is that I had this thing rooted way back when I first got it, but have recently restored to factory settings. So I know its been able to boot to SD in the past.... I don't know what could of changed or how to undo it.
Any and all replies appreciated thanks.

I am so embarrassed. Hey thanks for all the work you have done here with the nook color. I just Googled my model number... this is a Nook Tablet... not a Nook Color. /sigh. Off to follow the Tablet instructions.
I've spent hours at this now, and Im kind of wondering if my Nook Color is damaged in a way that it allows CWM to think it's written an image to the EMMC but it is actually failing to write anything.
I still have cyanoboot on the device, it still goes into Cyanogenmod boot screen and sits there indefinitely OR it reboots a couple times and gets stuck loading infinitely.
This is AFTER I have tried imaging it back to stock, CM 11, formatting it's partitions with the images on this site and various other things.
So either there is something common in all these tasks Im just blindly missing each time I try this and read/watch another tutorial that doesn't work out for me.....or something is wrong with my the Nook Color.
Can't even do the 8 failed reboots thing Im ASSUMING because the cyanoboot thing is there catching all the failed attempts.
Hadn't used the Nook Color in awhile because my wireless router died and it was kinda pointless to try to use it...now got a nice new router and the damn Nook is making me want to strangle it. So it was in some state other than stock, and I really don't remember if I was trying something new or if it worked fine when the router died at this point. I am just trying to get it to some point where it boots into some kinda of OS so I got some kind of baseline to start from at this point.
So ideas? I can get more specific if need be on what exactly I tried if it seems relevant, but I pretty much pulled the images and guides off the various posts referenced all over the net back to this forum. Hoping I missed something, going to be rather upset if this device is essentially dead since I haven't used it a whole lot since purchase..
First off, make sure you really have a Nook Color and not a Nook Tablet. The Color has a black bezel and the Tablet is silver. If it is a Tablet, the files on this forum will not work.
If you really have a Color, you need to explain more the steps you have taken to try to revive it before we can help.

It's a Nook Color, I've actually rooted and put it back to stock over a year ago. But even the methods I used then will not remove the Cyanoboot or whatever version of CM it's trying to boot into that never goes anywhere.
I've tried
http://forum.xda-developers.com/showthread.php?t=1759558
To see if it's a partition problem AFTER I tried to rewrite the boot/etc to stock and CM 11 with no luck.
Even went to Youtube to make sure I Was getting the proper screens and responses from the device.
https://www.youtube.com/watch?v=vUEoFPApfeQ To try to restore it.
https://www.youtube.com/watch?v=pj_DGZaKwBw To try to put a different version of CWM on it.
Used this link for GApps http://wiki.cyanogenmod.org/w/Gapps, I tried the "small" version along side CM 11
Tried using http://forum.xda-developers.com/showpost.php?p=22809801&postcount=148 to try to restore it to a Nook Color rom.
Tried following http://forum.xda-developers.com/showthread.php?t=2653483 Which is a collection of help postings on the Nook Color....havent had any luck with anything on there.
http://download.cyanogenmod.org/?device=encore&type=snapshot is where I got my images for the Nook Color Cyanogenmod. I used M12, with no results.
And while Im posting all the stuff I used.... I had http://forum.xda-developers.com/showpost.php?p=50438799&postcount=4 opened if I ever got it to boot into CM to use for further issues....maybe it'll help someone else.
And I can't tell you what order I did them all in at this point because I tried and retried different things. And I still have cyanobootloader coming up, if I select EMMC recovery it goes to what looks like a barnes and noble original screen to me and says "Install failed". If I let it do the standard EMMC bootup it just loads forever.
I HAVE NOT tried to load a bootable SD with the OS, etc on it because I was trying to get the device to work properly on the EMMC first. But if that is something that needs to be done to fix it, I can do that if you point me in the right direction. I'll even try to use ADB on it if I can get some kind of guide to it...most of the ones I found were no longer valid /missing links and other things with just a few random command lines but no images or anything to use and I didn't want to risk screwing the device up even more.
Thanks.
The reason you see "install failed" when trying to go to internal recovery is because you still have stock recovery installed on internal memory.
And after you did the partition repair and you want to install CM11, you must upgrade your recovery to v6045 or newer before flashing the CM11 zip.

Is this referring to the CWM version on the SD card, EMMC or both? I used some of the premade images for booting and they were all older versions of CWM.
I believe I attempted to use "cwm-6.0.5.0-encore-emmc+sd.zip" when I attempted to install CM11. If it wasn't that one it was "cwm-6.0.4.7-encore-signed.zip". It was CM11 Snapshot M12 with gapps-kk-20140105 since it's smaller than 20140606. It did the blue text scrolling install of both, autodetecting gapps and installing it. Then removed both from the SD card when I did it. I didn't catch any errors.
I have not been able to get the Nook Color to enter the CWM version on the EMMC to verify it's version number....but this may be because Cyanoboot is catching it or Im doing something wrong.
If I were going to describe this problem on a PC, I'd say it was pointed at a corrupted boot device and ignoring the one you're trying to use in it's place.

Blue text scrolling means you are trying to install to SD, not emmc.
What are you trying to install, emmc or SD? If trying for SD, you are using files made for emmc.
If you want to go back to stock, go to my NC tips thread linked in my signature and use an older version of CWM to flash the stock zip from item A15 there.

Really Im just trying to get what's on it, replaced with something that is functional so I can tell when Im doing something right or wrong.
I will attempt to do this again and try to document it a little better. I would like the EMMC to be functional at the very least no matter what version it ends up being... I will attempt stock again from your guide which I thought I did right the other night but Ill try it again.
OK.
Using:
NookColor-emmc-format-partitions-5-6-7-8.zip
TWRP-2.1.8-bootable-SD-encore.zip
nookcolor_1_4_3.signed.zip
I imaged the TWRP img onto an SD, copied both zips onto it.
Put it in the Nook Color, powered on and I saw the cyanoboot, then it loaded into TWRP.
From the install menu I installed the format partitions zip. It ran without errors. I wiped the cache/dalvik.
Then went back into the install menu and ran the nookcolor_1_4_3signed.zip. I see this:
-- Install /sdcard/nookcolor_1_4_3_signed.zip ...

Error flashing zip '/sdcard/nookcolor_1_4_3_signed.zip'
I will try it with another microSD card just incase it's defective.......and then see if trying another signed nookcolor might work from the guide.
Tried a different micro sd and used signed version 1.4.1 stock.
Did same steps. It errors, but as soon as it errors, it's like the TWRP resets real fast and gets the blue boot screen, flickers a couple times then rolls back and away to show the buttons again...takes 30 seconds or so.

Try it using the CWM instead of TWRP.

Ok... I'm using CWM 6.0.1.2 from your guide. Format partitions zip and 1.4.3 stock signed that I used prior.
I just got done flashing the format and then stock to the nook color and no errors are reported untill...
I just finished writing Nookcolor_1_4_3_signed.zip...
Finding update packing
opening update package
installing update
boot files...
Install from sdcard complete.
And here's the first errors:
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
I don't know if they mean anything, but something similar popped up in other attempts. I am rebooting device now to see what happens.
Going to EMMC 01 in top left of Cyanoboot screen....blank screen...waiting.
Cyanomod rotating load screen comes up. And if it holds true, it'll do this until the battery dies.
I don't think the stuff is being written to the EMMC. Which...maybe it's damaged or maybe there's some kind of lock out in place preventing it that needs turned off?
If I can get it running off an SD I'll be happy at this point...perhaps it'll be easier to tell if the EMMC is screwed up then.. If you are out of ideas or think it's damaged. Only reasons I can think of since it's been sitting for a couple months is was kind of near a speaker and I know magnets can damage HDs but really strong magnets can fry phones and stuff....so might have gotten the EMMC in some weird way.
Or some sort of power surge got it when I had it plugged in before I stopped using it.
Did you try my partition repair zips from my partition repair thread linked in my signature?

Yes I tried 1-4-5-6-7-8 and the separate 2 one. But if you want me to try again I can.....any specific version of CWM you want me to use?

I've always liked the v5504. If the repairs do not work, something is wrong with the NC.

I figured.......I'll try it a little later and see if any luck with the repair partition zips..but I doubt it.
Meanwhile, I should probably get you to point me to some SD images to see if I can get it to boot up into CM something and work successfully off the SD card.
I'm hoping I can find a way to fix the EMMC once Im able to successfully boot the device....or even with ADB. I dunno. Pisses me off since I never used the Nook excessively and took pains to keep it safe.
Oh and I saw people asking for specific partition repair files (like unique to their device), does that sound like a possibility here?

Go to my NC SD installation instruction thread linked in my signature to install CM to SD. I recommend CM10.1.3 from the CM site.
You can also put stock on SD. See my NC Tips thread, item B11 in the second post there.

So using 5504 of CWM with your partition repairs did nothing...still has cyanoboot and infinite load screen.
Working on SD installation now base on your recommendations.
Is there something you can think of that could be done from the SD boot to diagnose the EMMC more? It doesn't seem like there's really anything coming up on google even remotely similar to my issue.
And I've done this once with a much larger SD card but it had kind of **** transfer speeds so it might be defective... So Im repeating it as I type this.
Generic-sdcard-v1.3......rev8c.zip is what I used to image the card.
Then I used CM-11-20141112-SNAPSHOT-M12-encore.zip
and gapps-kk-20140606-signed.zip
The device ran through all the blue text and turned itself off. Loaded up with Cyanoboot going to SD01 and then it would blank screen for awhile and reboot...and repeat itself.
Now this one just error with not enough space on google apps, but Im going to see if the thing will even attempt to boot up.
Then Ill try your recommended version of CM...I already had all these images and was just hoping to see some results after all this.
OK. Some kind of success....
I actually got it to boot up using your rev8c, CM 10.1.3 and gapps-jb-20130301
BUT it gives TONS of popup errors....I was able to get through the setups somewhat. But once it's at the desktop...
I see
Unfortunately, Email has stopped. ----- Press OK then I get
Unfortunately, Trebuchet has stopped. --- Press OK, back to email.
I can kind of get into the settings and stuff, but with the continuous errors popping up it's hard to do anything productive.
So I'm going to let it sit and see if you have any input on that. I find it weird that it loaded with this version...but not the other.
As soon as I got it connected to the wireless network, a couple errors popped up, screen flashed and it went back to the cyanogenmod loading screen WITHOUT rebooting.
I don't even know what information would be useful at this point, lol.
