So I've been using my NC for a while flashing roms no problem. I tried honeycomb emmc and it works but I want to go back to cm7. Didn't make a nandroid backup (wanted to start from scratch on purpose) . I can reflash honeycomb fine. I can also always boot to cwr from my recovery SD I made. What am I doing wrong to prevent cm7 from booting after flashed? I want to continue loading cm7 from emmc, not the SD card. Any ideas?
Should add I've tried cm7 nightly 114 and another 103 I believe, which was working perfectly before I flashed honeycomb. It displays the cm7 boot logo then just an all black but still powered on screen. Never makes it to the boot animation.
Kinda at a loss for ideas here. I'm sure it is something simple that I missed, but I'm not finding anything like this on XDA. Right now my nook is either booting to recovery and sitting there, or just a totally useless paperweight. I know it isn't bricked, I just don't know what else to try to get back to CM7.
shamless bump. I have spare time today to play with this.
Did you wipe /system and /data before you flashed CM7?
Absolutely.

Are there additional steps I'm missing? This is the first issue I've had flashing the nook or any android device.

I seem to recall CM7 not booting for me after one of my play sessions. Although I hadn't loaded Honeycomb. The only way I could get back was to flash Nook 1.2 from a CWR sdcard and start over.
I just flashed nook froyo 1.2 that keeps CWR and still am unable to boot. If it wasn't for booting to my CWR SD, I'd be scared I bricked it.
What are some known good ways to get back to 100% stock? I don't mind re-rooting. Is there a RUU file or something?
I also recall having to remove the emmc CWR that ROMmanager installed (without really asking or making clear what it was doing).
In the DEV section there's a zip that removes the CWR boot and returns to stock boot. I'd try that.
I'm surprised there are no experts on hand to offer more guidance - it's a bit like sleepy hollow here!
I did try that zip if we are thinking of the same thing. IDK what is going on. I can't get it to boot on 1.0.1 BN, 1.2 BN, CM7....I'm really worried now.
Sorry this is not an answer to your question, but I wondered why you didn't like honeycomb and want to go back to cm7?

Honeycomb isn't a complete port... it has no hardware acceleration and doesn't do a lot of things that CM7 can, probably due to the nonavailability of the source code.
Also, OP, try this: http://forum.xda-developers.com/showthread.php?t=914690&highlight=stock

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??
Hello all,
N00b here with a question.
I am running CM7 off an SD card and my stock OS is updated to 1.4.1. Is there a way that I can boot into Stock NC OS while using CM7 (and vice-versa)? I love CM7 but my nook magazine subscriptions only work on the NC stock OS and I don't want to have to take the SD card out each time I want to read one of my magazines. Sorry if this is a stupid question. I looked for the answer for a few times but couldn't find it.
Thanks in advance.
If you have latest version of cm7 you hold down the n key when it reboots and the boot menu comes up choose to reboot into either emmc or sd card.

Thanks, worked perfectly!
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.

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!

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

ive recently purchased a nook color version 1.3 and did all the steps to build cm7 on sd ard inserted it into my nook it downloaded then rebot and seem to come up im cm7 but my touch screen isnt working any suggestions?
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.
