I thank you for your efforts and documented guide. I followed it and reflashed modded recovery at 300 mb size.i redid the recovery on my known memory card as well. Despite two cards with modded recovery,it still fails to show up any sign of life. What you suggest,thanks again.

Not really sure what you did by your description. But if you burned a card with one of my CWM images and that card failed to cause the NC to turn on or boot, that may mean the card was not burned properly. There are many things that can go wrong when burning that make the card unbootable. Look at my item A9 in my NC Tips thread linked in my signature.

You are sure it is a Nook Color rather than a Nook Tablet? A Tablet has a silver bezel.

The only way that I know is to get a CWM SD to boot. And you can't seem to get that to happen.
Did you try plugging the USB into your PC while the CWM SD is inserted?

[Q] So I bought this Nook color off Craigslist....

Excited as all outdoors because it was already rooted. Got home, sat down and went to put in my information, hmmmmmm, I got it from a black guy but there's a asian gmail account. :sirens: Maybe he purchased it from the guy just as I've done. I enter my account info and try to remove his, the apps need his so I cant delete him. Nothing a wipe won't fix right? Wrong. So after reading here a very small amount I realize I may need the original owner's B&N account info to resolve this.
Anyone care to chime in on this before I bother this guy for my money back?
Try to do a full wipe and return to original firmware. Then register an account for BN. Flash to cm7 afterwards. Hopefully it will work.

If you use another rom like cm7 you won't have to worry about it. They don't register anything with Barnes and noble.

If you are already at CM7 on the NC, then you will have to delete the old gmail and youtube accounts and sign-in to your own gmail and youtube accounts.
I just did a complete wipe of everything (SD card included) and his information disappeared. Thanks for the replies! Now to really dig into this.

Try to do the 8 failed boots and you shouldn't have to worry about it...
8 failed = system recovery (will take it back to stock)
update to 1.2 if necessary
register with B&N if not going to CM7 (I do it anyway even using CM7)
Root or CM7
Now its how YOU want it... not some asian girl/guy/whatever.

If you are using CM7, the "CyanogenMod 7" logo appears when booted. There is no registration of the NC with CM7. CM7 is not rooting. It is firmware that replaces the B&N firmware.
A rooted NC will initially splash the "Read Forever tm" logo when booted. The older B&N firmware splashed "Touch the Future of Reading" logo, if I remember correctly. A rooted NC is the stock B&N firmware that has been altered to allow (root) access to the Android Market apps and still retain all the original B&N functions/features. A rooted NC does require registering the NC.
If the rooted NC is not registered to your B&N account, then:
1. Touch the "U" with the up-arrow icon, select Settings.
2. In Settings, select Device Info.
3. In Device Info, select Erase & Deregister Device.
4. Touch the Erase & Deregister Device button to start the process.
5. Follow any other instructions to complete the erase and deregister the NC process which may follow.
6. Reboot NC, it should return to stock setup, as when it was new.
7. Follow the instructions and register the device using your own B&N account.
8. Update NC to 1.2.
9. Root NC using ManualNooter 4.6.16. Instructions are here.
10. Enjoy!
I hope this helps.
Thanks for the info Bluepen.....I now have a new issue. Somehow, someway I've managed to be in a boot loop, the funny part is it's flashing between the CM7 splash and ClockworkMod Recovery. I've been searching since last evening to no avail, not one single instance matches this one.
Any help would be greatly appreciated.
I've tried the 8x boot thing, I can't tell if it's even shutting down. Also tried the three finger deal, may need to do more research on that one. I've also formatted my sdcard so basically I'm in route to stock which I don't mind if I can just get there.
Slowly but surely this thing will run like my Shift...!!!!! I got it, basically I'm registered with B&N and on the stock ROM, WHEWWWW!
I went to nookdevs.com ( http://mrm3.net/nook-color-recover-any-bricked-device/ ) along with the help perusing around here I was able to fix.
Cyanogen is up and running again.....

It is good that your NC is back running CM7!
Are you dual booting from/on emmc or booting from the micro sdHC memory card or have you applied CM7 to emmc overwriting theB&N firmware?
Sent from my NOOKcolor using XDA Premium App
I've overwritten the B&N firmware, so I guess out of those three options it would be the latter.

Congrats. Now overclock the **** out of it =D and install the tegra 2 games.
Sooo....I try to to reboot and I get hung up in Recovery. The only way to reboot is to remove the SD card.
Anyone else experience this?

So amongst all my stupor I realize (after reading so much more) that I need to remove the SD card to boot back into cm7 or stock once I'm done in CWM. What a difference that makes. Smh.

Or format the uSD to remove CWM and make it usable to yourCM7 install.

Will that allow me to not have to remove it everytime and what are the chances of getting Nook Stock to boot once its formatted?

The reason I ask that is because I've been stuck on the "N" screen several times to no avail.

I don't know what you mean by factory reset. Do you mean the the 8 failed boot reset? That would be gone because you just wiped your device of everything completely. You were only supposed to do the partition 2 repair. Now you need to finish the process and reinstall stock.
Flash the format zip and go to my tips thread linked in my signature and look at item A15. It tells you how to put stock back on the nook.

Nook Color (Won't Boot/Hold Charge)

Hey guys ,
Just wondering 1st thing does the Nook Color only boot through the sdcard?
and i don't think it will hold a charge, not too sure hasn't been turning on for about 6 months now and i think it's bricked not too sure.
I have it charging right now and the light is orange on the charger so it might be charging. I will let it charge and see what happens.
The nook color is rooted with CWM recovery and wit cyanogenmod ROM just don't know what versions of both if you ask and it's needed.
Any help will be appreciated if you need more information please reply and i will tell you.
Another thing is my nook won't show up on my computer so i can't try and fix it from this thread http://forum.xda-developers.com/showthread.php?t=949699
UPDATE: I guess it's fully charged by the green light on the cord, just still won't boot or connect to my computer so i can get it to boot up, so please help me fix this issue. :crying:

Yeah i tried that last night and i tried again 20 minutes ago, would help if my computer would recognize the nook color.
Had to use an old phone to burn the .img file and put it back into my nook and still won't boot up
EDIT: It booted up so now i am downloading CM 10.2 is that a good ROM to flash?

You say you got it booting, but you do not burn by hooking the device to a computer, you take the SD out and insert into the PC. And any ROM should fix it. Try the same one you currently have installed.

[Q] Help! Cannot upgrade Cyanogenmod.

I have a nook color with CM7 (7.2). I want to upgrade to the new 10.2. How ever I seem to be having issues doing so. I tried going into the boot menu and doing the recovery mode but it never works. Sometimes the Barnes and Noble error comes up and asks if I want to restore to factory and even that brings back the old CM7. So can someone please help me either get this thing back to stock B&N so I can root it again fresh, or is there a way to upgrade this I am not getting? I installed the rom on the eMMC.
Thanks for the help. If this doent make sense or you need more info please dont hesitate to ask. My terminology isnt to sharp on this stuff.

You probably don't have CWM installed to internal memory. That B&N error is the stock recovery. You must make a bootable CWM SD to get CWM. Go to my NC Tips thread linked in my signature and make one per item A10.

After you make the SD, put the CM zip and gapps zip on the SD and boot to it. Then use the CWM to install zip from SD.

It acts like its installing the ROMs but you take the so card out and power on, and it

It is possible that your NC internal memory has become read only. I have seen this happen rarely before. It acts like you are writing to it but nothing sticks. Successfully flashing the repair 14567 zip should have caused it to boot to cwm when you remove the SD. I am afraid your unit is toast.

I finally got everything to work. I was going to throw the NC away, and decided I would try one more time, and it worked. The results were after I flashed the partition 1,etc... and it would not do anything, until I flashed the partition 2, and still nothing, until I flashed the NC stock update.
BUT.... I just posted a new question, about it will only go to Stock 1.2. It will not let me
put 1.4 NC update on it, nor any of the custom Rom's ? Is there anything more I can do?
