[Q] Please help a noob in need!

Hi everyone! Please help me! I've spent most of the last 18 hours on this, rested, and have come back hoping to start today off positively.
I have a new "blue dot" nook with the new partitioning scheme. Not realizing that, I tried to install CM7 internally using a youtube video from huskermania (sorry, XDAforums will not let me link). All went fine, I assume, except for an error in Clockwork that read: Error: can't format /data" error. I believe, after researching, this is a result of the change in partitioning.
Frustrated that I had bricked my nook, and not really wanting to run an internal anyways so I can revert back to regular ROM if I want, I tried to unroot using directions from huskermania again. I really thought it had worked, but it is now stuck on the rainbow Nook Color screen, which will disappear and come back repeatedly.
Please help. My goal is to reinstall the original ROM, then try to install another using SD, but that's not my main priority right now.

HURRAY!!!!
Ok, success!!!! I cannot believe something finally worked. The 8 step reboot did not work, but using power, home, and +volume did.
I am saving the SD card I used to reboot this. Any thoughts on the best way to root a new "blue dot" nook using external so I don ever have this issue again? I know I need to change the partitioning, but I'm still not sure how, even after reading what Maurice Mongeon has to say in his post "how to repartition a blue dot nook color." Thoughts?

How exactly did you finally get it to work? I've done the exact same thing and I'm not sure what to do next. I have a refurbed NC that came with 1.2 installed and I rooted it with manualnooter and immediately flashed CM7.02 stable from CWM 3.0.2.8. It had all kinds of force close issues so I tried to restore to stock but keep getting stuck on the boot animation. I re-flashed CM7 and it still works but I still have all kinds of force close issues. When I try to format data in CWM it says can't format /data! I'm kind of at a loss right now...
UPDATE: Got it working. I had been using the wrong cwm...

Flashed Honeycomb fine, cant get back to CM7

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.

Trying to unroor.

I have followed all the guides to unroot my nook. I was on cm7. I get to cwm. And format everything the guides say but when I format data. I get error. I then install the nook restore file and all is fine till it gets to nook screen animation then it keeps looping. Maybe thus is normal. Please help

Good luck with the unroor. I've even searched for that and came up with nothing.

I'm wondering if you are running into partition issues...?
I had originally installed CM7 on my NC using eyeballer's guide here, [GUIDE] Install CM7, OC kernel + Clockworkmod to EMMC - ALL NOOKS! (Updated:7/14/11).
It was about this time that I had seen reference to nooks with different partition schemes. I had one of the newer NCs where they (B&N) allocated 5GB of the EMMC to books and apps, etc. and 1GB available to us the users to put music, etc. on.
Previous NC's had the partitions reversed. 1GB available for books, apps, etc. and 5GB available to the users to load their own music, etc.
The second post of eyeballer's guide contains more information regarding the partitions issue.
I had decided that I wanted to go dual boot, leaving my stock B&N ROM on the NC and CM7 on the uSD. So I used eyeballer's guide above to load the stock ROM back onto the NC without issue. I just substituted the stock ROM in place of the CM7 and GAPPS files.
I then used verygreen's guide, [ROM][CM7] [v1.3] Size-agnostic SD Card image and CM7 installer for SD Cards. to set up my dual boot environment.
It was all very straight forward with no issues. In fact, I just upgraded from a uSD of 8GB to 16GB using verygreen's guide once again and using the latest nightly (138). The first time from a new install and was amazed that Google re-sync'd everything! I only had to install a few apps as opposed to all of them! The sync even restored my wallpapers, etc... all automatic!
NOTE: If you decide to use eyeballer's guide AND you choose to use any of the newer nightlies of CM7, Dalingrin's OC utility has been incorporated into the newer nightly builds of CM7 so you do not have to install this separately anymore.
If you choose to use verygreen's guide to opt for a dual boot scenario, you can hold down the "n" button when you first see the green banner/splash-screen (before you see the blue "Loading..." message) to enter an interactive screen to choose whether you want to boot from the device or the uSD.
This interactive boot process exists in the newer CM7 builds independently of which guide you use, so you should be able to achieve a dual boot environment easily... You could leave CM7 on your NC and put the stock B&N ROM on the uSD

First a little clarification. You have not "rooted" the Nook, you replaced the ROM with a custom ROM (CM7). Rooting is simply opening up the stock system without replacing the ROM. So if you followed instructions for un-rooting that was the problem. Unless you have a real need to go back to stock, I would make sure you have the latest version of CWR (v. 3.2.0.1) first and then reinstall CM7. The new version of CWR will prevent that error message you originally got as well as any freezing when trying to wipe the Davlik cache. Once installed, if you still do not want to keep CM7 follow the instruction for restoring the stock ROM, not for "un-rooting".

i did the same as pitmanr2003, but after i encountered this problem i di the 8x reboot, and it proceeded to "installing update", im guessing that worked. Now it says "Read Forever" when i boot up, but i get stuck into a loop at the same stage. Im having a little trouble trying to do what u said to do in post #3 though.

Black Screen after Read Forever on boot

My Nook Color was running the stock rooted 1.4.2 and tonight I decided to install CWM from Rom Manager and backup the rom so I could install CM10. The install of CWM through Rom Manager went well but when I did the backup it rebooted and now I get a black screen after the Read Forever screen.
I've tried the 8 interrupted boots which has worked for me in the past but that doesn't seem to work. I've also tried t use a bootable sd card - uNooter, per the CM10 wiki instructions for Nook Color here: http://wiki.cyanogenmod.org/w/Install_CM_for_encore
I know it's pretty hard to brick this thing, but did this actually do it? Any suggestions?

I was able to get it back to stock with A 15/A 10 of this post. http://forum.xda-developers.com/showthread.php?p=25354258#post25354258
Just follow the directions and then once it's re-flashed I did a reset by holding the n and pressing power. It'll boot back into stock.
Now that I was able to get it back, I just need to find proper directions for installing CM10.

Returning to CM7 and Nook won't access Market

Hello XDA peeps.
I've had my Nook color for about 3+ years. Have had both my wife and mine running old versions of CM7 on the SD card without issue.
I recently dug mine out to set up for the kids (for a trip we're taking starting this weekend) and first installed CM10 (10.3 I think). loaded and was able to get apps running w/o issue but the poor old Nook and CM10 was so sluggish I felt it was just too much for this legacy device, so I reflashed to the CM7.2.0 [stable]
loaded just fine, but when I went to install GAPPS it installed fine, but will not allow me to access my account now.
no matter how many times I try, it tells me the password does not match for my account.
I know for a fact the password is the right one, and I can get on the Play store just fine on my Galaxy S3 using the same credentials.
I even reflashed the GAPPS to an older version and no luck.
Any thoughts? Really stuck here, since we're leaving Saturday morning and I want to have both Nooks up and running current versions of our boys fav games to pass the time. right now it has no app store, so it's pretty much a stripped Android tablet.

You said you were running CM7 on SD. How did you install the CM10? Then what did you do to get back to CM7? What wiping did you do?

I actually have the CM10 on the root of the device. I thought I had put it on the SD card, but didn't. (just found this out by accidentally powering on the tablet w/o the card in it)
So, currently downloading the CM 10.2.1 update (from 10.1.3), and perhaps it will fix the sluggishness.
I have a third stock Nook that I have not touched in years that I'm going to flash on the SD card...see if I can't get it to CM7.2 w/o any issues.
but previously I had wiped the card twice and attempted to Reinstall CM7.2.
I think the fault lies in the steps I was following to burn the SD card.
Told me to add the gapps AFTER installing CM7
I was pretty sure in the past I put both on the same SD at the same time.
or it is possible the Google two-step verification/authorization is not compatible with the older Market app. I can get on the Play store just fine on CM10 (but it did have me open in the browser to verify the device).

I don't think CM10.2 is going to help. CM7 is the best for NC. I would wipe the internal CM10 you have on there and install CM7 to internal. Be sure to put the right gingerbread gapps on there too.

yes, thank you. I feel anything higher than CM7 just boggs the processor on these dated tablets. For a kids' tablet, it's just fine and will run most of their games/books and it remains snappy. CM10 just feels overloaded. It is sluggish and slow to respond. I'll try to get it moved back to CM7.
I've been trying to flash the other Nook, but after much effort, I have not been able to get it to boot into recovery.
I have the same card set-up, but I cannot get it to start with the card....constantly goes to the B&N root.

Sometimes it is difficult to get the NC to boot from an SD. See my NC Tips thread linked in my signature and read section A9.

Thanks Leapinlar,
Still running into issues. now on BOTH Nooks.
I was pretty sure I remember something about an updated B&N ROM that was signaled with a Green sticker on the box, which the troublesome boot one has.
I am using the generic_sdcard_v1.3.img + cm-7.2.0-encore.zip + gapps-gb-20110828-signed.zip all being burned via Terminal on Mac.
The only thing that has changed since I was dabbling with these in the past was the CM release.
I am not able to find my original bookmark of the tutorial I used to use (2+ years ago) so I think there might be a flaw in the instructions I'm following now. (for instance, the instructions I'm following now, the dd= command isn't proceeded by 'sudo' and without the sudo command, it errors out when trying to write the generic SD image to the disc (says disc is not available or locked).
gonna keep trying, because I want to get these up and working for our trip...we have 36+ hours of driving over the course of a week, so I know they'll get bored of looking at sights, reading books, watching DVDs, etc. Mainly for my own sanity, since I'll be driving.
**EDIT* i found the original tutorial I used years ago in my trove of bookmarks. It was the original GlassKeys tutorial. gonna give that a shot and report back with my success/errors.

Well, one thing, if you are going to use that old original image file you need to rename the CM zip to begin with update-. That will not help with the booting issue, but will make it so that image will recognize the CM zip.
I have an updated image zip in my updated instructions for NC SD installs linked in my signature.

Thanks. should have mentioned that I did rename the file to "update"
got my old CM10 to boot into Linux penguin and it seemed to be doing it's thing, after formatting the SD card following the GlassKeys instructions, but it is now booting to CM10 still by default and if I hold the "n" key for the boot menu on Cyanoboot and try to boot from SD card (normal or recovery) it just stays on that screen until I power it down.
as for the second, untouched Nook, I did the GlassKeys instructions to the SD card for that and it loaded to Penguin and went through all the install procedures, but now it still boots to the B&N emm setup screen.
wish I had never taken the other to CM10. now I have two Nooks that aren't acting properly.
thing that bugs me is the first one was running fine, just market wouldn't recognize my sign-in...now both are jacked.:silly:

SUCCESS!!!
So thank you goes out to leapinlar!!!
I dropped what I had been doing on my system as far as the files I was burning and read over all your FAQ and tutorial.
I downloaded the files in your how-to and had the tricky OE ROM flashed in a jiff!
The second one is installing now on the peguin screen and JUST now loaded to the CM7.2 bootloader screen.
Still used the GlassKeys instrucitons on how to burn via Terminal on OS X, but used your files (generic-sdcard-v1.3-CM7-9-10-10.1-10.2-11-largest-Rev8c.zip )
My original issue, I have found through all this, was that the Market wouldn't allow me to sign in...well that is an issue with the 2-step verification for my Google account I had activated (someone tried to hack my account, so I had it on). Once I turned it off, I was able to open the market and sign in.
Thanks again for your help leapinlar....check this one off!
Going to update both tonight with our boys' fav apps and games and get ready to hit the road first thing Sat morning! :laugh:

If you want something newer I found that cm10.0 was pretty fast on nook color. Better than cm7. Anything newer I also found was to slow and laggy 10.1+. If interested the last nightly cm10.0 rom and gapps are over in the development fourm.
