Highly doubting anything can help me unbrick my Nook Color[SERIOUS]

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.

[Q] {Q} trouble with a stock 1.3.0 nook color

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?

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.

@bobstro
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

[Q] Messed up the format of Internal Memory of Nook Color!!! Plz help!!!!

Hello xda experts!!!!! I really need some help!!! The thing is like this : I have installed cm10 alpha 1 for nook on sd card!!! While i was installing it my nook color was also connected to the computer. So in WinImage i accidently chose the 1 gb of nook color instead of the 32 gb sandisk class 10 which i had inserted in pc via card reader. So it began writing on nook color's internal 1 gb memory. More to that, I interrupted this procedure and performed full format in minitool partition manager. i didnt knew the format of internal memory of nook color so i chose fat32 formatting style. But when i rebooted nook color after disconnecting it kept on showing message that system has encountered some issue and it requires the system to restart.But even after reboot the same error kept on showing up!!!!! And since yesterday the stock b&n OS has stopped working completely!!! Doesnt even show the error which it previously used to show!!! Plz resolve this error and help ASAP!!!!!!!!!!!!!!!

Use my partition repair zips in my emmc partition repair thread linked in my signature. Flash with my bootable CWM SD in my tips thread also linked in my signature. Then you can reflash stock back to emmc as also explained in my tips thread.

Bricked while installing TWRP
Hi guys,
sorry to warm up this thread, but I think I have a similar Problem. I was running CMW with CM10.1 and I tried to install TWRP using the manager app, bit I think I chose the wrong model and now I am stuck with a loop of the nook logo at the beginning. I cant even boot from sd card or anything. Does somebody have an idea how to fix this?

You probably messed up you partitions. Go to my NC partition repair thread linked in my signature. But you will somehow have to get the NC to boot to SD. Also make sure you really have a Color instead of a Nook Tablet. Colors have a black bezel and Tablets have a grey one.

Thx leapinlar,
infact I do have an Nook HD+. Problem is I cant get it to boot from SD. I already tried the HD+ bootable CMW-Images u posted in ur other thread, however it never gets out of the nook-logo loop. It seems like the partitions are so messed up that it cant boot from sd... could one somehow solve this by connection the thing to a pc?
Cheers!

Hard Bricked...... in a wierd way.

So guys i have bricked my nook. Doesn't turn on or anything no screen flashing or anything. if anyone could help me on this i would appreciate it.
Well i was on cm 10 and 10.1 for a while and i finally decided to try other roms. i installed every rom on my internal so not my sd card. (my sd is 32 gig sandisk class 10 ultra). so i updated my recovery to flash more roms and when i did cwm didnt read all my backups. cwm only read my cm7 backup and cm10 backup. (using clockwork recovery). So first i installed SCHIZOID p.a.c. rom. But on that rom everytime i wanted to boot up i would have to full wipe + reflash rom without it getting into a bootloop. Then i tried Mirage's cm7.2 rom. When i flashed that rom, the loading bar in cwm would get too about 3 quarters and BAM! My nook would turn off and only load the bootloader. so from the bootloader i opened up cwm recovery and went straight to my backup, and apparently, dumbass cwm says theres no boot.img or system.img and data.img....etc in my cm7 backup. so i went to my cm10 backup and that said md5 mismatch. WTF??? So i tried to reflash Mirage's cm7.2 rom and BAM! same thing happen, but about 7/8ths of the bar was filled before it force shut down by itself. But this time i cant access the bootloader and i have it ultimateley hard bricked.
so please if anyone has any un-hard brick or jtag repair threads or anything i would appreciate it. And would a bootable sd fix this? the screen wont turn on/flash or anything so im not sure if it will load the sd card
Edit: I've found out that plugging the nook to my computer and holding the power button for 20+ seconds makes my computer make a sound that my windows machine recognizes the nook but then it quickly makes another sound and my computer doesn't recognize/thinks the nooks disconnected

Leapinlar has an excellent guide.

Edit: I've found out that plugging the nook to my computer and holding the power button for 20+ seconds makes my computer make a sound that my windows machine recognizes the nook but then it quickly makes another sound and my computer doesn't recognize/thinks the nooks disconnected

The reason it appears to not turn on is your boot files in the boot partition are corrupt.
The way the NC boots is it turns on without the screen on and looks for valid boot files first in the SD and then in the internal boot partition. If it finds some, it turns the screen on and continues the boot. If it finds none, it immediately turn off without ever turning the screen on. That Windows beep is the short turn on/turn off sequence.
So the solution is to make a bootable CWM SD per the thread the last user referenced and boot to that. Then you can flash a valid ROM and it should repair itself. If it does not successfully flash a ROM then go to my partition repair thread linked in my signature and follow instructions there.

how do i boot into cwm? I get a explanation mark in a triangle in a nook saying that it needs to connect to power, I did let it charge and tried holding the power button + nook key + volume up to boot into and when it does i get the sign that says i need to connect to power. Once charged, would it boot me into cyanoboot, and then from there go to cm? (I'm using slow charge since I lost the nook charging kit so I use the nexus 4 or samsung galaxy s2 t989 charger). and I put my cm10.1 may 31st rom on the sd card + gapps, so when I do boot in cwm, can I access it and flash it?
edit:nvm got cwm working. But u cant flash a rom.
I wipe everything (data, cache, system,dalvik) and then when i hit chose zip from sdcard it says:
Finding update package...
Opening update package...
Installing update...
set_perm: some changes failed
E:Error in /sdcard/cm-10.1-20130531-nightly-encore.zip
(status 7)
Installation aborted.

Nevermind i got it working. i have to unmount every partion + turn on 'toggle signature verification' Thank You leapinlar.

cant even boot to bootable sd

Im hoping that you might be able to help me out here. I can not even get the NC to start up with the bootable sd. Am I completely bricked? Ive also tried the partition repair youve referenced to no avail.
edit: Tried eyeballer image and was able to get into recovery but not able to mount any /cache or the sd card to try and install new rom. Any suggestions are greatly appreciated!

How did you try the partition repair if you can't get the bootable SD to boot?
It is very difficult to make a bootable CWM SD that will actually boot in the Nook Color. Look at my NC Tips thread linked in my signature at item A9.
It is likely not bricked, just in need of repair. Make sure you have it charged and follow the steps in A9.

Thanks, going to try now! Now that you've said it, I obviously hadn't tried the partition repair but thought that I had. Do you have a suggestion for which partition to fix? Fingers Crossed!

Tried both of your cwm bootable sd's and I am unable to get either booted. Also, when plugging into pc, get the malfunction error you talked about in one of your tips. I really appreciate your help, any other advice that I might be able to try?

Only what I have in that A9 item about different things to try to make it bootable, like using an external USB card order, etc.

Thanks! Ive been using win32diskimager, perhaps i'll try winimage. I'm not really understanding why eyeballer cwm would work but not yours. Weird. Thanks again!

Well I can get into cwm with eyeballer but it gives me an error stating that it can not mount /cache and it will not mount the sd so that I can't flash any .zip files

Aren't you the one I was helping in another thread sometime back? Did you try the trick of using your PC to copy the uImage and uRamdisk files from my SD to eyeballer's and try booting that?

Nope, not me. New to the NC (have rooted my htc and samsung phones though so not a total noob..lol). I will try what you've suggested. Perhaps some background is needed. I had my NC running smoothly with cyanogenmod 10.1 nightly. Tried updating to RC3 and during flash the screen went black and Im here now trying anything I can.

How do I install CM11?

I followed leapinlar's instructions for installing to a SD card and have that working. I used another SD card and followed their thread for clearing the other partitions. If I try to boot without the SD card the cyanogenmod bootloader screen comes up and then eventually just goes to a back-lit screen, so I assume that means the old CM10 is removed from the system. What I can't figure out how to do is to actually install CM11 "in" the Nook Color instead of on a SD card. I tried this with TWRP but it wants some kind of md5sum files and I don't know what they should be called or the syntax of what they should include (just the md5sum?) so it refuses to install.
Any help would be greatly appreciated!
Thanks in advance!

You need to follow steven676's CM11 thread in the dev section. And he has a new CWM v6048 that must be used. See here:

Thanks for your always excellent help! i'll jump over to that thread now.

I think I bricked my Nook
I checked out the thread you pointed to and saw that cm11 is still "experimental" if you will. With that in mind, I decided to go back to CM10.1.3. I have run into a "slight" problem - my Nook won't power on. I shut it down when it was on the purple "do nothing" screen after I had cleared everything via one of your threads and after booting CM11 from the SD card. I may have tried powering on with nothing in there - where I did get cmrecovery but nothing booted (got in a loop). I then powered if off using the power button. Now it simply won't power on. Did I completely brick this thing? Sorry of the dumb questions, but I really don't know much about all of this.
Thanks again!

The device needs valid boot files installed or it won't turn on. Those boot files can be internal or on a bootable SD. Try making a new bootable CWM SD and see if that boots.

I tried doing that but still no luck - it just doesn't even power on at all. I searched the net and found a thread where someone had to disconnect the battery for a few seconds, connect it again, and then it would boot again (like me, from a SD card).
So....I got the back cover loose - couldn't get it all the way off due the microSD slot. Noticed the battery leads in a cutout in the metal. Could get that dang thing loose, but I did manage to get the ground wire off there for just a few seconds and then put it back. Bingo! Booted a SD with 10.2 and gapps using TWRP and got everything back to normal again. Whew!
I'm quite familiar with electronics, and every piece of hardware on a PC down to the component level doesn't bother me, but I don't know anything about the Nook hardware or software. I feel like I just got very lucky!
Thanks again for your tutorials, scripts and answers here on the forums!
