When I first got my NC, I installed CM7 on an sd card.. quickly found out that it wasnt stable enough for me and I installed CM7 on emmc. I'm selling my nook to a friend and want to return it to stock with no CWM on it.
Before I installed CM7 on emmc I made a backup of my stock setup. Should I restore this backup or wipe everything and use the zip of 1.2 without CWM (this guide: http://forum.xda-developers.com/showthread.php?t=931720)?
I want to return the nook to how it was on the day I bought it when I first took it out of the box. Are there any other steps I have do to unregister it or anything? He wants to be able to purchase books through B&N with it and all that.
Thanks
The 1.2 .zip is probably simplest. It will definitely leave the NC de-registered without any extra steps.
So I guess I'll follow the guide for a clean 1.2 install. I will then be able to update to 1.3 correct?
Edit: Also, my nook is a blue dot, with the newer partitions. If that matters at all.
Hmm, I'm not sure how the 1.2 image will interact with the newer partitions--that thread you linked and the one with the 1.2 image are both pre-blue-dot, with no mention of how the new partitions interact with those methods. Your best bet may be to clear CWM off eMMC and do 8 failed boots, to be safe.
So instead of messing with the 1.2 zip, should I instead restore the clean stock backup that I made using CWM before I installed CM7 on emmc? If I read correctly, I can unregister the nook in the stock nook settings and then re-register it. I think. Basically I want to make take my personal information off of it and put his on.
I guess I don't HAVE to take off CWM, unless it will cause problems? The person I'm giving the nook to is not very computer literate and I don't want him to have any problems down the road.
My thinking is, if you restore from your back up image (presumably made via CWM on eMMC), it will not remove CWM. The 1.2 image from this thread might install just fine as long as your CWM is up to date (3.2.0.1), but I'm not 100% sure of it. Your safest bet may be to repartition first using this thread: http://forum.xda-developers.com/showthread.php?t=1094371
Unless, of course, someone can confirm that the 1.2 image works with blue-dot NCs. If your friend wants the 5GB /data instead of /media, there's another zip in the repartition thread you can use after you're back to stock.
ETA: the main problem CWM would cause is blocking future B&N updates.
ETA2: if you're a gambler, you could just try the 1.2 image (make sure you have CWM 3.2.0.1). If it won't boot, try 8 failed boots to restore. If it still won't boot, you'll need to make a CWM SD card and repartition anyway.
Just rebooted into recovery and my CWM version is 3.2.0.1. CWM has gotta go then, since I want him to be able to receive all future updates.
You could also just google around a little bit, there's a guide to repartition the NC back to pre-bluedot partitions.
It's pretty simple. I did it to mine prior to installing CM7.
Here's a guide: http://mrm3.net/nook-color-how-to-blue-dot-nook-color/
Also, from my understanding the newer partitions shouldn't affect any roms being loaded... including the stock one. They're all made to fit on the original 1gb partition, so they'll fit fine on the 5gb one.
Here's a similar thread to this though. http://forum.xda-developers.com/showthread.php?t=1125675
Success.
Didn't mess with any partitioning. Put the 1.2 zip without CWM on an sd card, booted into recovery, wiped /system and /data, installed the zip, wiped /cache and dalvik cache. Rebooted into stock 1.3 with zero problems. Downloaded the 1.3 update with zero problems. Loving it.
Thanks all!
Are there any other steps I have do to unregister it or anything?

I know, its not truly bricked. But as of right now it'll only power up if connected to USB power source and will only boot as far as landscape Android text with a blinking underscore. Part of why I didn't get it fixed last night was my unwillingness to leave and aquire a larger micro SD card. I'll be leaving work in a couple hours to go get some stuff to get this thing working again (its 2 days old) heres the recovery plan:
Aquire 4GB + MSD card
Flash a stock 1.1 ROM (the one thats pre-rooted here)
Install (sideload) that stock joint
Read that Elephant book that comes with the Nook because its working again
From there I'm a little confused. Can I flash Clockwork to a MSD and then use that to flash CM7? Or am I oversimplifying here?
From my trial and error the only thing I have gotten to "un-brick" is to boot into monsters pack then switch cards (i used the 128mb version and it removed the rest of the space on my 2gig card) then format cache and system in the mount section of clockwork. then head to install zip and installed a complete restore to 1.0.1. when thats done I head to BN site and got the side load to 1.1.whatever and let it do its thing. From there your up to date and just like new and can then try and "re-brick" it. Ive had mine for less than a week and done this a few times now cause I am never satisfied.........
The nook is never bricked unless it has a hardware failure. One of the great things about the nook is that it has a very early hook in the boot sequence that checks for presence of a bootable SD card. Creating a bootable SD card is easy. Follow the thread which instructs how to make a CWM bootable SD card. You need to choose between the EXT3 or EXT4 version depending on which ROM you will flash. CM7 requires EXT4 version of CWM. If you try to use the wrong CWM version you will get the outcome that you just observed, stuck at android text. If you want to flash the stock 1.1 rom, then you'll need the CWM EXT3 version.
I had the exact same issue. I used this:
The internal CWR workaround is ugly to say the least. So if you NC should refuse to boot or bootloops, which I hope won't, flash this boot repair that I'm adding just in case. Just flash it, no need for formatting.. Use a bootable CWR SD Card.

That makes things much clearer for me. I knew CM7 required EXT4, but was unaware that the CWM flashed MSD would be properly formatted and couldent be bothered to boot in Linux to do it. Blame lack of sleep. Thanks!
I don't know where to turn. I started a thread about my effed up nook but it got deleted (my fault) I'm completely at my wits end here. I had NookFroyo .68 working just fine on mine but like an IDIOT I thought it would be neat to try out CM7. Big mistake would not get past the animated N screen no matter what. I got the SD version of the Customized Nook Froyo to boot up but its very slow and stuff doesn't work. How do I get a ROM back on the eMMC? Some one suggested I get CWR and a ROM on the card and flash it via CWR off the card onto the eMMC. How exactly do I do this? I CANNOT get the winimage method to work no matter what I do and I don't know WHAT I'm doing wrong. Everytime I direct winimage to the place I've downloaded an image to, theres nothing there....
I thought I ALMOST had it a few minutes ago. I can get the CWR to come up and I flashed the flashable eMMC NF. I got my hopes up as it started to boot BUT OF COURSE NOT - went into a boot loop, constantly doing the N screen over and over. WTF.
I'm desperate here. I'm at the point where I'm willing to pay someone a small fee to help me get this sorted out. I'm going to keep on trying....
on win image, when you go to select the file. you must change the file types it see's to everything. that will let you see the .img file you downloaded.
We are talking about Win32disk imager right? It only gives the *img selection.

I'm reading the "Recovery" thread. Should I do the "repartiion" zip file? I'm starting to think that maybe the problem...
EDIT: Tried the Repartion.zip. No change. Still continously reboots.
I just tried the Nook restore file and it still gets hung up on a different N screen (the Nook symbol). What in the HECK! It wont' go into CWR anymore, says there isn't any room on the card. AN 8GB CARD!!!! I put the card back in the computer and it says its only 115MB! WHAT THE HELL IS GOING ON HERE.
EDIT X2: LOOKS LIKE I GOT IT BACK TO STOCK. WHEW! Now I can start over! Tomorrow after I rest a bit. LOL

Hi,
I found this post (in developers/cm7 users thread) very useful for installing
CM7:
http://forum.xda-developers.com/showpost.php?p=11535969&postcount=151
It is a little dated (weeks) but very detailed and should hopefully still all work fine.
Some more general information on:
http://nookdevs.com/Portal:NookColor
I find that I never have enough uSD cards to use - so make sure that
you have several spare. The emmc Androids are still in general expecting
an external SD card for storing data such as ebooks etc. and CWM will
backup to the external cards too.
CM7 and Froyo use different disk format types for various partitions, don't know,
but that may be part of your problem?
Your PC won't normally read some of the linux partitions on the SD card
either - hence only 115MB showing. This is the boot partition, formatted with
FAT32 (a PC related format) In general you don't need to reformat this partition,
just update or change some of the files. (Some of the names of formats used include:
FAT32, EXT3 and EXT4)
CM7/17 and CM7/19 Have both been very stable and easy to use for me. I switched
to CM7 from Froyo 6.8 a week or so ago.
Good luck, the Color Nook is a fun device!
Peter
Thanks all I appreciate the help. I used some HP utility to take care of the cards, worked great.
Ok I've got a NF .68 up and running. Titanium backup worked beautifully. SetCPU is running it at 1.1 interactive..... HOWEVER!....
I flashed it with a another version of the CWM flashable .68 NF that I had previously. I tried to reflash the other version and it went to install then stated "Installation aborted". I tried twice and got the same thing. I guess its no big deal since their the same version just this one thats on there had some more tweaks hence the title "Customized".
My question is why did it do that? My guess I was supposed to format or clear the data/system/caches' in CWR. Is that right? If so, which ones precisly do I clear or format before flashing a new ROM? I'm starting to think thats' what happened when I tried to load CM7 (Yes I had CWR 3010) and go me all borked to begin with....
And if someone would like to answer a quick question. What this EXT4 stuff and how does it pertain to flashing ROMs? Thanks guys... Your advice got me back up and running!

Always format /system, /data, and /cache. Whatever you do DO NOT format /boot.
As to why you may have had an issue on trying the other ROM. My guess is it has to do with what version of CWR you had been using and wha twas on the device prior to flashing it. I've found if you make say a nandroid backup using 3.0.0.6 or earlier, and are currently using CWR 3.0.1.0 they don't mix well. And I think it has to do with the fact the older CWR version only supported ext3, and the newer one has ext3 and ext4 support. So once you install a ROM using CWR 3.0.1.0 that uses ext4, and then you try to go back to a ROM that is ext3 it just doens't work out like planned.
That all said I not longer flash CWR to eMMC, and I have a bootable sdcard running 3.0.1.0 with all my current and old backup files. Make life much much easier IMO seeing as you can always boot to an sdcard, and all backups are in the correct format and will Restore just fine.
Thanks for the info! I'm sure that will make trying to upgrade to CM7 actually work! LOL!
But first can someone explain to me what this EXT3/4 stuff is?
Different filesystems for Linux/Android. Wikipedia has pages for each if you want google them and get too much info
Too much info? No thanks! As you can see I can barely handle the info I'm getting now!
All I see are instructions on how to use ADB or to use CWM to flash to the external SD. Is there a way to use CWM ready CM7 for the internal flash?
Hi,
If I understand your question, you would like to run CyanogenMOD7 off the
internal memory also called emmc, rather than running it off the external
memory or uSD card.
Though a bit dated, I found this walk-through to be very detailed:

Hope this is what you are looking for.

It is helpful, however I am looking for a CWM ready version....so far no luck.
Hi,
The instructions in:
http://forum.xda-developers.com/showthread.php?t=960542&page=16
Are assuming running from uSD version of CWM.
Following other CWM install instructions you can end up with CWM installed
on the internal flash, emmc.
For example:
http://forum.xda-developers.com/showthread.php?t=971197
Minor issue to watch for: the versions of CWM that support EXT4, required
for CM7 also require a different kernel.
I'm not quite sure what you mean by CWM ready version of CM7... the CM7
nightlies are in a .zip file that is flashed by CWM running off the EMMC boot
partition. The first time you install CM7 you also have to use CWM to
reformat some of the partitions on the EMMC (to ext4), but after that you can
use CWM to update the flash each time.
ROMManager can also be used to download ROMS and start CWM.
I am in 'updating' mode, I usually download a recent CM7 nightly and
recent overclock Kernel on PC, then share to Nook using Dropbox.
On Nook, I download .zips from Dropbox and move to root of the data
SD card. I also have latest Google apps (GAPPS) in Dropbox or SD card.
I then use ROMManager to run CWM to backup entire ROM.
Then I use ROMManager to boot into CWM and individually:
Install from .zip: nightlyxxx.zip (Current CM7 version)
Install from .zip GAPPSxxx.zip (Current google apps version)
Install from .zip kernelxxx.zip (Current OC kernel, overwrites the CM7 version)
Then I wipe cache partition.
Then finally wipe dalvik partition - CWM freezes here.
Reboot and wait a while (5 mins) (I assume it is rebuilding dalvik cache here)
Often seem to need another reboot and wait.
Hope this helps...

Thanks, that does clarify things. I'm new at this and do it was a little confusing to me how to do it. In the captivate forum they're a little more forward on how it's done. I appreciate the help. I tried using the rc4 encore signed but it seems to stop at the startup with N color on it. I thought I formatted all the partitions properly. Is there something I did wrong?
Hi,
I haven't had the problem of being stuck at 'N', but I'm sure there are plenty of
others that have... it will be something simple, probably missed one step in install.
Perhaps check through the list you followed and try and remember if you forgot
one step, or didn't understand one of the steps.
My install no longer shows the "N" at all when booting, so I'm guessing that
there is a missing piece somewhere!
I get:
"Touch the Future of Reading"
Brief flash of "Loading"
Few seconds of sideways "android..."
Then an animated CyanogenMOD logo for more seconds.
Here is one (long) thread about booting problems, but there are other ones too.

Got the problem fixed. Had to boot to a different CWM and format as ext4. Now all is well.
Speed Comparison
I have CM7 flashed to a class 4 sd card and it seems a little slow compared to the stock elcair build. Does CM7 installed to the internal memory speed things up a bit or does the system still seem a little slow. I'd like to know before I flash to my internal memory.
It should be faster on the internal, logically speaking, but perhaps with the right SD card you'll get comparable speed.
So I bought a used (barely) nook color off of craigslist today for 200 with a screen protector and 8 GB transcend class 6 microSD. The guy I bought it from had his google account on it though so I tried to remove it. Basically I did the imaging through terminal (i cantp ost a link) and put the new stuff on and now it says my memory stick is damaged (even though it mounts on my computer) and it freezes my NC whenever it is in
I'm basically wonder, HOW CAN I GET MY CM7 2.3 NC to reset itself so I can put my own account on it. I have searched but can't find anything that good, as I have clockwork, but the rom is installed ON the NC internal, not on the microSD...Please help me out in some kind of step by step way. I rooted my droid eris myself, but starting with it pre-rooted has messed me up.
http://forum.xda-developers.com/showthread.php?t=1030227 start with this thread.
You should have ROM manager on there already. Reflash CM7 and wipe data...should take you to a fresh install.
Sent from my NookColor using XDA Premium App
So what step do I start out if I have clockwork mod on there already? I dont have recovery though.
Go into your programs and open ROM Manager (this assumes that you already have clockworkmod installed). Make sure that you have a micro SD card in the Nook with your desired CM7 build (either nightly or stable). Then Click on Install ROM from SD Card. Click on the ROM that you want to flash. It will then give you the option to Backup Existing ROM and/or Wipe Data and Cache. Go ahead and select Wipe Data and Cache. Hit OK and the Nook will do the rest automagically. (ROM Manager may request Superuser status, go ahead and grant it or it will not work). After you regain control, you should have a fresh, clean install of CM7 to work from.
I use the SD card method to have the nook boot into CM7 and when the SD card is pulled, the nook would be stock to be used by my kids. But I think I messed things up and can't restore. Here is what I have done:
1- I tried to update the stock version to 1.3 manually from B&N website but soon realized I could not. It seems like when in CM7, I had tried to flash CWM recovery (which was not needed and is pretty buggy in SD card method for nook). Now the recovery in emmc appears to be CWM.
2-for some stupid reason when I got into CMM recovery, I formatted boot, system,data and cache (not sure if I did boot also or not). My thinking was to flash a stock image and be fixed. But I am now stuck.
Is there a way to go back to stock on the nook? I am still able to boot into SD card and CM7 nightly. Oh ya, I use Linux Ubuntu not windows. TIA
Sounds like you should get the system back to stock before proceeding any further.
Follow the instruction here: http://www.nookdevs.com/NookColor_UnRooting
The problem is that I get into the CWM recovery and not given the reset option following the options on that page. Any idea?
I think my problem is that I'm not really rooted in true sense since I was running off the SD card. Maybe I shoudl root properly, then unroot?
I did kind of the same thing once. I made an Sd card image with CWM on another sd card -- basically as if you are going to install CM7 to emmc. However, once you get to the point where you would flash Cm7, use the stock zip ROM. It will install that to emmc so it will be back to normal. You should then be good to go.

If you follow the instructions you should be left with an unrooted initialized stock Nook Color. Register your account. Then you can wait for the NC to download the 1.3 update, or side load it. Once that is installed you have an unrooted 1.3 stock system.
From there you can try your CM7 card. Don't forget to remove your SD card at the very beginning since like a PC the NC will try to boot off the SD card if it is present.

when I follow the instruction, I am not given the factory reset option. I am stuck at the n screen. It flashed the read forever but then stuck at the n screen. Do I have to wait longer than 5 minutes?
None of this is mine, I owe it ALL to the threads mentioned below.
So as in many posts on XDA say, it's almost impossible to brick the Nook. What a great device. I had to format my SD card to use it to "un-brick" my nook but it was done. I Mainly used the info here http://forum.xda-developers.com/showthread.php?t=949699
Burnt a bootable CWM image onto my SD card. It took a while doing it with dd in Linux. I'm sure it's the same in Windows or Mac. It took about 20-30 minutes. It also took a while to unzip/extract the img file from the downloaded file. Be patient
Then used the CWM recovery remover file from http://forum.xda-developers.com/showthread.php?t=914690 to remove my CWM recovery and used the 1.0.1 file from same thread to flash the stock image onto the nook.
Once the SD card is ready, just drop those files in the root of the sd card. It should have 4 other files in it to boot into CWM recovery from the sd card and let you use the menus to flash those two zip files. It took a while but it's all in those threads. Thanks to the members. Now lets see if I can go up to 1.3 and then root it again.
