I'm trying to find out what changed in my Nook Color boot files which is preventing me from booting CM7 from an SD card. What directories, partitions should be on the Nook color eMMC and which ones are responsible for booting?
The boot priority is hardware controlled. Is it possible your card is loose or somehow not making contact? I have to replace a Nook because the spring broke and it would no longer hold the card in place.

OK....I'm not nearly as computer literate as most of you on here so please forgive me.
I have a nook color that I boot with an SD card. I don't know what kind it just says nookie fryo when it boots up (or should I say used to)
When I take the card out it still boots up as a regular nook with no problems. But with the card in the screen will flash....it says loading....then it just says andriod in the top left corner and has a black screen.
I have searched and searched these forums and frankly you guys are speaking greek to me so if you are kind enough to help me out I will take no offense to you explaining this to me like I'm a kindergartner.
Thanks.
If your bootable SD card was working before, and not working now, and you have not changed anything on the card, and your boot from internal memory (stock B&N firmware) still works, I would hazard to guess that your SD card has gone bad. I would get a new SD card, remake the bootable version of whatever you want to run, and see if that fixes the problem.
SD cards arent meant to run Operating Systems. They will go bad.
Hi guys, since a couple days im the proud and happy owner of a Nook color. Before this I had an Archos 70IT, but the nook kicks its ass any day of the week.
But... i am having a bit of a hard time getting familliar with all the terms and policies that come in play when "hacking" the nook.
Mine is rooted using the "burn SD card method". I downloaded a copy of CWM and burned it to my SD, along with the uIMage and uRamdisk files and the latest version of Phiremod. Booted up in recovery, flashed Phiremod and set everything up.
Now, on the forum i see a lot of talk about EMMC and SD cards and running the ROMs from them.
What exactly do these two things mean? Where do I run my ROM from? Which is the preferred/fastest/most stable method?
What is the overall preferred method of flashing/running ROMs?
For example, i cannot seem to boot into recovery anymore because i formatted the "boot SD card" after flashing the ROM. On my phone I am used to just hold vol down and power on to boot into recovery.
This blog may help you sort things out:

EMMC = internal memory ( Electronic Multi Media Card ) it's basically a SD card that's installed inside your device from the mfr. It's the 8GB of memory your Nook color has
SD - is your microSD card
You can run your ROM from either place. Depending on where you have it installed - but the NC - boot priority starts with the SD card - so if you've got a boot ROM installed on your SD - you'll boot from there. Otherwise it'll boot to your NC EMMC - and the SD card will be data.

Right - you booted off your SD card - and then erased it - so now there's no longer a boot file on your SD card - and now run off EMMC for boot ROM.
You can choose which memory to boot from - if you have a quality brand - fast SD card - the speed difference is minimal from what I've read. So far, I've kept the Nook software in tact for Warranty reasons - and it's easy to reformat a SD card if I want to get the memory back after a ROM install makes the drive " TINY " for storage purposes.
Check out the development section if you want to read more about SD card options - or EMMC ROM installs.

It's actually "embedded" multimedia card...but yeah...
I found out my Nook cannot be registered because I live in holland. You need a United Stated IP address to be able to register. Something with license to buy ebooks online.
So the Nook stock software is kinda useless in Dual boot for me.
I burned a CWM recovery SD card, flased the latest Phiremod and formated the SD so I am assuming im running off of the EMMC...

If your machine can boot into Phiremod - with no SD card in your nook - when you power it up - then you're running off the EMMC.
Hi. I am awaiting delivery of a new NC which I ordered after reading about "nooting" and running Honeycomb etc. I am a total noob and trying to get my head round all the different procedures has left me a bit confused! Can someone tell me if I'm right in the following : 1) My new NC should be (or will be after connecting to WiFi) system version 1.3. 2) If it is, and I do not want to mess with the internal ROM/booting/processes, it is possible to install HC on a 4Gb SD card along with an "img" file called phiremod 6.2 (available from :http://forum.xda-developers.com/showthread.php?t=1045018) in order to burn an image to the SD card that can just be stuck in and which will allow me to boot the NC into Honeycomb OR Phiremod depending on how the Nook's start button is pressed. 3) If I just want to use the original system, I can then just remove the SD card before powering on. I.e "Nooting" is not necessary if you go for the dual boot system? If I am right in the above, is there an up to date HC/phiremod image file for the Nook 1.3 as of this month (i'e newer than the one mentioned above) and could someone kindly point me to it?? Many thanks to all in advance, and sorry if this has been asked, but the info here is overwhelming!
That's what I did with mine. I'm running the Dual-Boot Phiremod 6.2 and Honeycomb from the SD card. The nice thing is with that image is the boot menu also gives you the option to boot from eMMC so you don't have to remove the SD card to boot into the stock OS.
Hi,
Having a with a Nook where it will not complete boot of CM7 which is installed on an SD card. Instead it boots into the Nook Color software.
I hold down the power button till I see the green Cyanogenmod logo with the Loading text, which I think means it is booting from the SD card (I can get it to boot into CM recover), then the screen goes blank and something goes wrong and the boot process continous with the 'n' screen and eventually loads the Nook boot animation and ends with the Nook software loaded. The nook software seems to be running fine except I can't get the SD card to boot all the way.
I've tried 2 known good SD cards, which boot without problems on my second nook, so I know it is not the SD card. I suspect something got corrupted with the boot process files, so I have been trying to find a way to overwrite the existing files with a virgin copy.
1) Can't get ADB running, I suspect the ADB route is only possible if I have the nook booting in a rooted CM7 in the first place (if some one could confirm that would help)
2) I have tried the x8 boot fail reset as well as the erase and deregister option in the nook software with no change in the above behaviour.
3) My last hope is to do an update back to stock using the recovery mode of the SD card. I can copy an updater file to the small partition of the SD card that is visible on Windows. I found a 1.2 stock updater, but it is ~200MB which is too big to fit on the SD card. If someone could point me to a smaller updater or a sd image with CWM and >200MB space that would be very helpful. TY!
What exactly are you trying to do? If you are just trying to set up dual-boot of CM off of your SD card, you don't need to do anything to the stock B&N internal install. I've had good luck using the procedure in the [ROM][CM7] [v1.3] Size-agnostic SD Card image and CM7 installer for SD Cards thread.
Are you sure the initial CM install on your SD card went well? It's known to be very particular (see top of that thread) about what SD cards work. The first few times I tried, I didn't realize there were error when CM was initially extracted which led to similar failures. From what you've described, the SD setup is failing. Normally, you don't need to worry too much about what's on the internal emmc setup of the Nook Color.

Hi bobsto, some background. I've been using CM7 on a microSD for several weeks now. I dual boot between Nook SW and CM7 that way. I've been using the link you posted above to create the SD cards and so far I have not had to touch the eMMC files at all.
Then a friend messed around with the Nook I gave them with CM7 on an SD card. I don't what the friend did, but when I got the Nook back it would not boot into CM7. I pulled my SD card from my working Nook and it wouldn't work either. So I'm guessing someone screwed with the Nook internal files. So I am trying the factory restore of the Nook SW to see if that will fix the problem and allow me to load CM7 from the SD card again. Interestingly Nookie will boot from SD and CM7 won't. Still trying stuff to see what will fix the problem. Suggestions are welcome.

Gosh, I wish someone could figure this out.
I restored original stock after a full CM7 root and it went fine but I can NOT get a dual boot sd card to work.
It seems to install but when I reboot it shows CM7 screen briefly then always boots to Nook OS.
Tried many many different cards and image writers and CM7's and even a card from my other Nook which I know works.
It will not boot into the CM7 from the SDcard.
Any help?

Try this for CM7 - http://forum.xda-developers.com/showthread.php?t=1022786
Nookie also works - http://forum.xda-developers.com/showthread.php?t=922324
Not sure what is going on, but it worked for me.

Thanks, the first worked like a charm!
I made a 32gb CM7 sdcard.
Still wish I could have got the size-agnostic card to work, it bugs me when I can't figure stuff out.

I'm in the same boat, but after 1 day of research and trial and error I'm happy it works. Maybe someone smarter will see this and know the answer and solve my problem curiousity.
Hi. I'm trying to fix a nephew's bricked Nook Color.
1. The device shows no obvious signs of damage.
2. I don't know what my nephew was last doing with the device before it bricked.
3. I have rooted phones and tablets of various manufacturers since Froyo. Not a nube.
4. I have used SDFormatter & Win32DiskImager to prep various sized and classed SD cards, but the Nook never reads from the Card.
5. The device will successfully factory reset, but that doesn't fix the boot issue.
6. LeapinLar seems to have the best tutorials. I just need to find a way in to restore what I believe to be a corrupted factory ROM. I'm hoping there is not an actual SD Card hardware issue.
7. Here are just some of the tutorials I have followed with no success:

Well, the first thing to determine is whether you really have a nook color. It might be a nook tablet. If it is a tablet the color SDs will not boot. You can tell by the color of the bezel. The nook color has a black bezel and the nook tablet has a silver bezel. You can also look for the model number on the back.

Well, I can't believe I missed that. I have a nook.
I'm sorry for wasting the post. I will start by trying a Nook Rom instead of Color Rom. It's a bit embarrassing how much time I spent in the Nook Color forums and missed that little obvious piece.
Thanks again for you help and quick response!:good:
