[Q] Nook Won't Boot Anything off SD

So I have been searching for someone with similar problems for a couple days now and none of the solutions I've found have worked.
My Problem: I had my Nook rooted and had a bootable Nookie card and everything was all good, until I decided that I wanted to mess around a little more and get CWR on it and everything. Well, somewhere along the line things got messed up and I flashed back to stock(8Reboot, along with Power/N data wipe. So I am back to 1.0.1. I have tried re-rooting about 15 times now, both with Auto-Nooter 2.12.25 for 1.0.1 and also with upgrading to 1.1.0 and using AN 3.0. I have tried writing the image both with the Win32DiskImager and also under Linux, using different computers. All of the files are showing up after the write, but when I powerdown the Nook, put the SDCard in and then plug in the Nook cable, it just boots up as normal. I can't seem to figure out what is wrong. All of the other posts I've read have seemed to be fixed by using a different card reader or OS or wiping and starting from scratch at stock, but that isn't working for me. If I missed any details, just let me know.
Thanks so much in advance!

If I were you, I would think there's something going on with the SD card. I would use both of these tools to make sure that I do not have some weird partition setup...
Easeus partition manager (free), to see what weird partitions you may have..
SD Formatter - and do a full wipe
Google for both. Then burn your new image (download it again, or perform a checksum - if provided from your source)
I've had a few seemingly good cards act pretty flukey at times, and I just use those two tools.. with great success.

Thanks BimBoy, I tried using both of the utilities to no avail. No defects found in the Partition Man, and I formatted it with the SD Formatter. Re-Wrote the image, and another straight boot-up. I am using the supplied img out of the original author's post and everything, so I know it's the correct one. It's the same I used a couple months ago.

1 - This is the Development Forum, there is a big Sticky Post saying not to post questions or problems here, but instead to put it in the General Forum. But even better would have been to post in the thread from the "original author's post" that your refer to.
2 - Please post the exact name of the image file you are burning in WinDisk32Imager to create your bootable SD file. The most likely scenario is that it is an SD file, but not a bootable one.
3 - In your original post, you talk about doing things to your Nook and doing things to your SD card. Then after that, you keep using unspecific words like "it" and "that" so no one knows whether you are talking about your Nook or your SD card - for example "put CWR on it" could refer to putting CWR on your Nook or CWR on your SD card.

Please refrain from posting in DEv section if there is no development behind it.
Thanks

What is uNooter?

I just got my Nook Color and am looking into how to go about rooting it for CM7. I checked out CM's Wiki page on it here and it mentioned using uNooter. I haven't read about this tool anywhere else and Google searches for it turn up practically nothing. Is this not the right tool to use? The forums mostly seem to mention ManualNooter, Auto-Nooter, etc. Also is it possible to flash CM7 on the internal memory and avoid using an SD card altogether?

Never heard of unooter and I've been reading theses forums since December. Auto mooter was to root the older firmware 1.0 ,1.01,and 1.1. Manualnooter is for the newer froyo firmware.

Rooting stock is not required to install CM7.
You simply need to create a Clockworkmod recovery microSD card and you can then flash CM7 (which is pre-rooted) from Clockworkmod.

Thanks. I figured this would be relatively easy compared to rooting and putting CM7 on my EVO but reading on here there seemed to be a few different approaches. Will that method allow me to flash CM7 to the eMMC, and after that point will I no longer need the SD card to boot? I ask because I don't have a card on hand and am considering backing up the contents from my phone's card and using that.

Correct.
You only need the SD to install a bootable CWM then you can flash CM7 from that. After words when CM7 is installed to eMMC you are able to use Rom Manager to install CWM to eMMC as well, so everything will be set up on the device's internal memory. SD is needed only for the initial boot of CWM to install CM7.

Thanks. From reading around it seems you can't use a phone or the Nook to mount the card and write the image, so I'll have to buy a reader and might as well get a card for the Nook at the same time. Since I'll be flashing CM7 to eMMC does it really matter if I get a class 4 or above card like many suggest? I'm not sure what's in my EVO but that is my benchmark. Class 2 seems to be what comes up in searches the most.

The general consensus it's to stick with Sandisk SD cards for the Nook. There are others that work as well but Sandisk it's pretty much a guarantee of zero issues. You can usually score an 8 GB class 4 Sandisk at Wal-mart for a Jackson.

I was the one that put together uNooter after being contacted by the individual that maintains the CyanogenMod wiki. They wanted a universal Nooter that would only root the device, install Superuser, ADB, RomManger, and work on all versions of the NC software. They asked that it be called uNooter. It is not released anywhere else, so that is why you did not see any mention of it on a Google search.

That information is really only relevant to running a ROM from the SD card. If you're only using the card for storage, or to get CM7 on eMMC, manufacturer and card class don't matter.

I wrote my image over USB to a card in the NC without a card reader. I've seen wiki guides saying there's a greater chance of the write getting interrupted, rendering the card unusable at least in the short term, but it worked for me. It was only when I wanted to revert the card to storage that I ended up needing a card reader. The links in my sig have a little more info about using the NC as your card reader, but you're probably better off just grabbing one.
Also, while CM7 does not require an SD card, many apps do. Your experience will be somewhat limited without one.

Great to hear directly from the source, thanks! I'm surprised more people don't point to your tool on the forums given that it's right on the CM Wiki. At this point I'm a little confused about the various approaches to do this. Does your tool install ROM Manager directly into the stock Nook interface, and then I flash from there, versus booting CWM off the SD as people mentioned earlier in the thread? Sorry if that's completely off-base.

Yeah, I thought about this as well and figured I'd want a full-time card for the device so I ordered a card with SD adapter. I figured the specs didn't matter at all for a data card but picked up a class 4 Sandisk anyway.

I received notice this past Monday that the cleaned up version of the CyanogenMod wiki was online, so not a whole lot of exposure for people to talk about it. I believe the old wiki had listed the different Auto-Nooter and Manual-Nooter that went with each software version, thus taking up a lot of space and confusion. AN and MN are more tailored to people that want to stick with the stock software, but enable full Android Market access. People that want to go from stock to CyanogenMod don’t need all the extra software that is bundled with AN and MN just to be able to flash CyanogenMod. By eliminating all the version specific software I was able to create a version that would work on all current, and hopefully future, software versions.
Yes, my versions will install Rom Manager directly into the interface. You would then allow Rom Manger to install CWM Recovery, and then you can download and install CyanogenMod from the device. You could also take a full backup of your current stock rom. Using uNooter or bootable CWM will both get you to where you want to go, it is really up to you on how you want to get there.

Instructions for installing CM7 to the eMMC using CWM on a SD card (which can later be reformatted for storage) is in this thread: http://forum.xda-developers.com/showthread.php?t=1030227.

GMPOWER and bigbob23: Thanks for the info, that was exactly what I needed to clear everything up. I suppose backing up the stock ROM would be useful in case I ever needed to restore it for warranty purposes or anything. I'm not sure which approach I'll go with, my SD card came today so I'll be reading over both techniques and giving one a shot!
Thanks again.

I went through the process with uNooter as outlined on the CM Wiki and it went perfectly. The only thing was I had to use SD Formatter and the earliest 0.1 version of Win32 Disk Imager to get the image to write to the SD card. Not sure if that problem is specific to Win7 64-bit but maybe I can mention it on the wiki.

I am glad that you got everything to work right. I think the problems that you might have experienced are more associated with win7 x64. My replacement laptop with win7 x64 will not be here for another two weeks for me to test it on, but in the past I have had to use Unlocker almost every time to unlock the usb drive before I could proceed with flashing using Win32 disk imager. On my current windows 7 x86 setup, I have yet had to use Unlocker to be able to flash an image with the win32 program. HERE is a post with people having problems in the past with win32 disk imager on win7 x64, they took the same path that you did with Panasonic SD Card Formatter to fix it.

uNooter
I guess this worked for the latest firmware of 1.2.0? (I am about to root one soon!) thanks in advance!)

I just got my nook last week so I'm assuming I had the latest factory firmware when rooting, but I didn't check.

If you see "Read Forever" when booting (stock) then "Yes" you have the latest firmware.

ADB after uNooter?
Above, GMPOWER mentioned ADB as one of the items uNooter installed. I've rooted with uNooter in part because *nothing* *else* I could find would actually boot on my NC and in part because I liked the idea of a relatively minimal root. I figured I could then push any apk's I wanted to add with adb.
Unfortunately, that doesn't seem to be working. I used "NookColor Tools -> All Settings -> Development" to enable USB debugging, but 'adb devices' shows nothing. If I plug in my G2 with CM7, adb finds it just fine, so I'm pretty sure I've got the computer side of things working. Any hints about getting the NC to play nice?

[Q] Newbie Nook Color owner needs guidance :-)

Hi all,
After reading all the great stuff about the NC recently, CM7, Phiremod and the honeycomb releases Ive convinced a mate of mine in California who's visting the UK to bring me one over to tinker with..
Now.. After doing some research Im overwhelmed with info and thought Id ask for "up to date" pointers..
1. Is there a straightforward guide to rooting and installing the NC, as I live in the UK Im not fussed about the original NC rom. I've seen Cyanogenmods wiki entry http://wiki.cyanogenmod.com/wiki/Barnes_&_Noble_Nook_Color:_Full_Update_Guide is this the best approach?
2. Which rom is best? Plain CM7, Phiremod or Honeycomb as posted by deeper blue?
3. Any other pointers?
Sorry for such basic questions, im just overloaded and not 100% sure which is the best process to take.
thanks all in advance
Angelo

Take a look in the stickies, there are comprehensive guides to root....just make sure you're using the correct version. If your mate is buying a brand new one for you, you'll most likely need the version for rooting with partitions. I have used all 3 of the roms you mentioned and my personal preference is CM. Phiremod is just a heavily themed version of CM and the honeycomb build is ok, but it lacks some features and is still a bit buggy because the source code has not been released for honeycomb
Sent from my DROIDX using XDA Premium App

If you decide on CM7 (which I personally recommend), I would look for "How to Install CynaogenMod 7 on the Nook Color" (can't post links) on YouTube. I personally found it very useful. If something seems off, make sure you look at the description and read some user comments. With the way this guy explains it it's practically idiot proof and it's unlikely you'll mess anything up.

thanks
Thanks Guys,
I've been doing more reading and yeah looks straightforward..
Considering Im not interested in the core B&N OS, I was thinking of installing CM7 to the internal memory and then perhaps installing Honeycomb (deeperblue version) on a memory stick to "play with".
From what I can tell the HC port is nice as a toy but not robust enough considering HC hasnt been released to AOSP.
Makes sense?

If you are looking to 'play with' honeycomb on a MicroSD install, check out http://forum.xda-developers.com/showthread.php?t=1045018
You get Honeycomb and Phiremod in a dual-boot image tailored for a MicroSD install.
Read through the thread and see if it's to your taste.

For the most usable ROM, go with CM7. Just follow this guide in this post. Very simple.
http://forum.xda-developers.com/showthread.php?t=1030227
The only issue is if you have a "blue dot" with the newer partition. Just read the RED text at the beginning of that post.
After you get this running, you can read up a little more and create a SD card w/ Honeycomb or Phiremod to play around with. But CM7 is the most stable out there (well, I guess Phiremod is good to, because it is a customized CM7).
Good Luck.

Use CM7, it's the best for now.
HC is beauty but still a lot of work to be done.

+1 for this guide!

"The only issue is if you have a "blue dot" with the newer partition. Just read the RED text at the beginning of that post."
For some reason I thought that statement was obsoleted, am I wrong?
It was valid if you have v1.2 NC and flashing with CwM Recovery prior to v3.2.xx.
But since the instructions do indicate using v3.2.0.1 CwM, then why care about blue-dot or not since it has been taken care off unless v3.2.x.x not properly does the job.

Maybe because you have a choice in partition schemes?

You really will want to repartition the new nook. 1 gb is a very small partition for your programs. 5gb works much better and the change is fairly painless.

That's a reasonable reason but again, it shouldn't be highlighted in RED, ORANGE at best
In fact, since it's a choice of good, it should be in GREEN.

thanks guys
Thanks guys, Im in awe with all the feedback and comments this thread is getting..
yes, Ive received the NC today and its charging Also doing loads and loads of reading
My nook does have a bluedot so my partitions are 5gb Data/1Gb Media.
I'll probably leave it like so, considering CWM supports this now its ok, and put most of my media on an external 16gb microsd card..
If Im right I can still install apps into the 5gb partition right?
Also , if I understand it correctly I can actually install CM7 onto a microSD and simply boot from this right ,without rooting/installing CWM... ?

You can still install apps into the /data partition but pls note: if your NC isn't rooted, you can only install apps that offered by B&N. You do not have full access of Android Market.
About CM7, yes, you can run CM7 off uSD and not touching the eMMC (aka internal memory) at all. Be considered getting a Sandisk (class 2 or class 4)

B-i-g thanks
All,
BIG Thanks to everyone,
I've successfully (actually flawlessly), repartitioned my nook to the old standard and installed CM7 into the internal memory..
All flawlessly. Also ordered a sandisk 16gb memory card from amazon.co.uk, so that will hold most of the media..
I was considering making the main partition >1Gb (1.9Gb) but decided to leave it as it is for now.. It was so easy yo tweak I thought Id try it vanilla and then grow if I need to..
Awesome-ness

ok wheres my 5gb?
ok got one question now..
/media is supposed to have 5gb available..
CM7 doesnt appear to allow me to use it as a SD card.. but ive found it mounted as /mnt/emmc
How does one use it ??? I tried downloading pdfs and I was told that an SD card was required for this... :-( when i get home I was going to try mounting it via usb to a computer but is that the only way?

There are 2 things you need to know
1. If you're running CM7, you MUST have a uSD. "MUST" does seem to be a strong word but for some reason, that I still try to figure out, an external uSD is required. W/o it, you can still using it but there's some apps won't run if no uSD plugged. It means the NC works 99.9% w/o uSD. I guess I should take the "MUST" back, ehhh
2. If you're running the recently nightly-build CM7, the USB storage utitlity should already be implemented within the ROM. All you need to do is
1. Connect NC and PC via USB cable
2. by this time, the usb indicator should be appeared on the NC, tab on it
3. Tab on Connect USB to transfer .......
4. Turn USB Mass Storage on
5. by this time, PC should recognize the /media on the NOOK
6. do what you want to do

Hey Angelo, I just wanted to share my experience.
I love gadgets, and tinkering with gadgets. I am an IT manager/minor programmer/webmaster, etc. etc... so no surprise that I feel right at home here BUT, I also love to read and I think that the Nook app for Android is bunk (e.g. "poor") compared to the stock NC experience.
I decided pretty early on that I wanted to keep the NC stock (partially due to warranty) and have a dual boot option for CM7. I had initially installed CM7 on my NC, replacing the stock rom all together. I ended up putting the stock ROM back on.
Here is a post from another thread where I outline that experience...and the guides that I use.
I talk about partitions in that post, since you have a new NC, don't even bother yourself with that...just note the guides there that will get you where you want to go, either way....

Many (older) apps in on Android are designed to ONLY look for storage called "sdcard". So your 5gb of internal (emmc) called "Media" will not be able to be utilized by those Apps.
Apps that are better programmed and designed can access the memory called "Media".

[Q] Old nook user / but now newbie again ..... info needed

I bought the original Nook Color back in Nov. 2010. I went through all the methods back in the day, when guys first started rooting the Nook and all the problems we had back then ... side loading apps ... adhoc issues ... B&N updates ect ... we got CWM recoveries and finally we got fully working froyo's and Gingerbread's. Then CM7's and the Phiredrop's.
I been through it all. I ended up giving my Nook to my son, and he loved it. I got into Android Development Cell (ROMS). I Now got my Nook back from my son. It is working, but I have forgotten a lot about how to mod it .... mainly the partition tables, and how the bootloader runs. Does it look to the eMMC first ? or the SD-Card ? Can we flash from both locations ?
Anyways ... He has it setup weird now. It has a dual boot menu, I can boot into CM7 or CM9, But it is acting up and some stuff doesn't work. He also says it can boot into Stock 1.4.2 somehow *shrug*
I have done some searching here on xda but it is a lot of OLD posts and dead links.
Could you guys help me out with a few questions ?
01) I would like to wipe EVERYTHING from eMMC abd SD-Card and start over. I know I can format the uSD and also format the eMMC, but Can I flash a SD with a CWM image and then install Stock 1.4.2 on the eMMC. Do I even need to install stock first ? What is the best method for this ?
02) Will I need to nooter my nook again at this point if I do that ?
03) Can I run CWM on the SD and run a nandroid backup to that same SD if it is a large SD-Card ? I thought I could since the bootloader looks at uSD first (but I guess it looks at the boot partition huh ? ) my son says NO you can not run CWM and have a nandroid backup on that same SD. Yes or No ?
Bottom line is this is what I’m trying to do……
01a) I could care less about stock B&N.
02a) I just want a Nook that will dual boot into CM7 and / or CM9 preferably from my 16 GIG SD-Card but it really doesn’t matter, as long as I can install app’s to the external SD-Card.
03a) I want a way to backup the entire CM7 or CM9 via CWM to my SD-Card.
NOTE: I have a (1) 16 GIG SD-Card (1) 4 GIG SD-Card and (1) 8 GIG SD-Card.
If you could help me out with any info at all on any of this, please do so. I am mostly Android literate and I have a working ADB on my win7. I just have forgotten exactly how the nook operates at the lowest level, and how the newer CM's are flashed now after a clean format
Thank you for your time and help to any of my questions.
Peace

The Nook Color boots from uSD first... then eMMC if there is no bootable uSD in the card slot.

Only if you want stock to be rooted... not necessary if are going to flash a different ROM to eMMC or don't care about stock root access. If you choose to root stock.... use this thread

03) Can I run CWM on the SD and run a nandroid backup to that same SD if it is a large SD-Card ? I thought I could since the bootloader looks at uSD first (but I guess it looks at the boot partition huh ? ) my son says NO you can not run CWM and have a nandroid backup on that same SD. Yes or No ?

Yes.... I do that frequently.. the thing is... the nandroid backup will be of the eMMC unless you use one of the modified CWM's designed for SD installs.
Additionally... if you are going to run that from a uSD with another ROM on it... you will certainly have to adjust the boot partition on the uSD to be large enough to hold the nandroid you are creating.

Bottom line is this is what I’m trying to do……
01a) I could care less about stock B&N.
02a) I just want a Nook that will dual boot into CM7 and / or CM9 preferably from my 16 GIG SD-Card but it really doesn’t matter, as long as I can install app’s to the external SD-Card.
03a) I want a way to backup the entire CM7 or CM9 via CWM to my SD-Card.
NOTE: I have a (1) 16 GIG SD-Card (1) 4 GIG SD-Card and (1) 8 GIG SD-Card.
If you could help me out with any info at all on any of this, please do so. I am mostly Android literate and I have a working ADB on my win7. I just have forgotten exactly how the nook operates at the lowest level, and how the newer CM's are flashed now after a clean format
Thank you for your time and help to any of my questions.
Peace

So you are saying that I can do it in this order:
1) Format eMMC ( only boot partition right ? )
2) Format uSD ( resize boot partition to a larger size for backups )
3) Create bootable CWM uSB ( any particular one you recommend ? )
4) Put one of the stocks 1.4.x files on the uSB then flash it
5) Put CM7 or CM9 on uSB and flash it
Question: Do I need to flash stock 1.4.x even tho I dont want it ? or can I skip step #4 ?
Thanks

Item 1) highly NOT recommended. There is no point to format /boot.
Item 2) if "uSD" means the external microSD card, then, no, you don't need to format it since it will be done in step 3 of your list.
Item 3) Get the CwMR version 3.2.0.1. And call it "flashable CwMR uSD", not uSB.
Item 4) If you don't want stock, leave it out as no point to touch it.
Item 5) After done step 3 above, put CM7 OR CM9 in there, the CwMR uSD, and flash.
Strongly suggestion: before doing anything. Be sure you know what you trying to do or at least, pls let us know what you try to accomplish. For example, do you try to run CM7 or CM9? Do you want to run it from the external uSD card or from eMMC? Instructions are different.

Hello -
Thank you for the update info. Glad I asked first. Thank you Dizzy for your help, you have been a big help to me in the past also. Votinh thank you for your reply. Looking back at what I wrote I see many mistakes in my process. Thanks for correcting them.
Now ... as to your question Votinh. What is it I am trying to do.
First off this is what I currently have. Nook is working, but not well and just a mess in general. Sometimes it locks up or just runs at a crawl. ( I have CPU oc'd to 1200 ) I have CM7 and CM9 but can't seem to boot into CM9 anymore at all. I also have CWM v3.2.0.1 installed on my external SD-Card with a nandroid backup.
I just want to erase it all and start over : )
I want my Nook to be able to Dual Boot into CM7 and CM9. I would like both CM9 and CM7 on my 16 GiG SD-Card, BUT if that is not easy or possible then I would like CM7 on internal and CM9 on external. I dont need stock.
If all else fails ... or just to complicated I could live with just CM9 (nightlies or stable) with all APPS installed to external SD. and forget about dual boot.
Again thank you .... and please ask me any more questions you might need to help clarify my goal.
Peace

So far, everything you've asked are doable, in fact, a lot of members currently having the same system you describe.
Firstly, "I would like both CM9 and CM7 on my 16 GiG SD-Card" is called "dual-boot, it is a true dual-boot.
Go thank "racks11479" for his tremendous work
Link: http://forum.xda-developers.com/showthread.php?t=1448186
Note: both CM7 AND CM9 are on the external uSD card.
Secondly, "then I would like CM7 on internal and CM9 on external."; since your wish is granted , this is just an option for you. Yes, you can easily install CM7 in eMMC (aka internal memory) and booting CM9 off uSD as you want.
For references:

Ok ... got it. But If I just want to install to SD external ... can I format the internal eMMC ? And my last question .... I see your signature and what you run. You recomend CM7.2RC1 MiRAGE KANG on eMMC and Dalingrins kernel. You like that setup the best ? I think I will try that setup now. What version of CWM should I use for that and were will CWM be eMMC also ? or can I backup to SDCard.
Thanks once again

Once again, NEVER format the eMMC short of a catastrophic event, (sometimes referred to in tech circles as a Mountain Dew Event.)
Mr72 has good instructions for getting 7.2 up and running on eMMC, http://forum.xda-developers.com/showthread.php?t=1443292

Dalingrins would be redundant as it is already part of this build. You *will* want to run the V6 script as it is well worth it.
Once you've got that going well you should have read around enough to be able to load CM9 nightlies on an SD card. You *do* have a Sandisk card, right?

In bold: sure, but what do you try to do? Format the internal so that you can install something else on it?
I currently have CM7.2-RC1 Kang running on eMMC, it is really good.
Booting off uSD is more like for experimental, play it for a while to see if we like it or not. For trying, I recommend using uSD.
I have not spent more time on CM9 since I don't see much of the benefit of it.
Also, MisRy covered pretty well there.

Thanks for the info Misry. I have many sd cards and have used them all will good results. My Sandisk is only 4 gig ... so it was not going to be my first choice. I also have a Class 4 8 Gig Kinston I was thinking of using. Or a Class 10 16 Gig Patriot, which I know people dont like, but it seems to work fine in my phones ....?

Magus-
The difference in the SD card class as far as speed comes down to the size of the information we want to write. The lower classes aren't very fast with the large hunks of info, but excel with the tiny byte exchange used in the ROM. As the speed of your system will really be affected by the slow I/O rates of something like a class 10, compromise on size before class. It may be counter intuitive, but people have given up on cyanogen in general only because they had the wrong sdcard. This is especially true if you have a dual boot and are running the ROM off of the sdcard itself.
Look at the "strange results or how I learned to love cm" or something thread. Google that with xda and nook and you'll find it. That has all the info you'd want and way more.
Do another book with Eddie Campbell and we'll call it square. You know you want to.

Well I was testing a homemade script and I believe I did in fact format eMMC and either scrambled the boot partition or deleted it also on emmc. No mater what I do I can not get eMMC to boot. I can boot cwm from SD-card, but nothing on eMMC.
Advice ?? please be as technical as needed. I do not have Linux right now, but I do have adb on win7 and 3 sd-cards
THanks

Well, let's see what we're working with...
$ su
# fdisk -l /dev/block/mmcblk0
Post the output of the above. It'll show what partitions are left (if any) and then we can take it from there. This can be a hassle indeed, and it will require some research as I have avoided doing this myself. I am hoping your ROM partition is still intact, at least.
Anybody else who can help, please do. I may not be able to respond as often as I would like.

I was gonna suggest 8+1 to see if we can get back to square one.
http://nookdevs.com/NookColor/RestoreToStock

He's gonna need a ROM partition for that to work.
For a long time, 8 failed boots would (as a last resort) result in a working Nook for just about every problem. But, as users are getting more experienced across the board, more advanced and dangerous stuff is being attempted.
When everything goes right, it can be pretty rewarding, but when it goes wrong...well, let's just say the solutions become a lot more advanced as well.
The output of the command will let us know which partitions are erased and if any are still intact. Considering the information we have so far, I am not hopeful. If the emmc was erased and formatted...well, we'll see.

Here's what has occoured:
over-wrote the following partitions with "0":
# 0p7 = /cache
# 0p1 = /boot
# 0p5 = /system
# 0p6 = /data
Then formatted 5-7 ext4. Flashing a ROM with a blank boot partition has been done on another device many times with no issues, for some odd reason this nook responded poorly and I believe the the boot.img never copied over to 0p1.
I am not sure what all he tried but I know he tried the flashable emmc fixer, which didnt' fix it. I am actually concerned that made it worse, but that's my opinion and I don't have my hands on the device. For what ever reason he couldn't get adb working with the device. I found this thread:
http://forum.xda-developers.com/showthread.php?t=919353
And since ADB wouldn't work, I wrote a script and created a flashable zip for him so it would perform the same operation, but it stopped saying bad zip. He tested it with 7zip and there were no errors, I checked my script and I see no errors in it and yes, I used a proper program for it as well, NotePad++. He's a bit frustrated and sending it to me. I am confident that if none of the things he tried didn't completely scramble the internal partitions that I can get it working. But if anyone has any idea as to why the script would fail, let me know.
Edit: And correct me if I am wrong, but it's the lack of a kernel which caused it to respond so badly. A similar thing happened on our phone but was due to powering off with a blank boot partition (not our noob moment but someone else's), but being that it's a tegra 2 system we have Nvflash and all is easily rectified. My theory is that there's something, most likely memory, which is loaded by the kernel and is required for a recovery to run.
He tried the 8 failed boot and it did bring up something which ended with an error about no boot partition, I'll try to get the picture he showed me later, I need to run off to work right now.

... Nevermind

First, why in heaven's name would you purposely want to write zeros on the boot partition?
Second, adb was not working because there was no kernel or ramdisk on the boot partition since you had him zero it out. Adb needs both.
If he was trying to flash your zip with CWM from a bootable SD card, then the zip needs to be properly signed before CWM will flash it. You can have CWM toggle off that check, but I doubt he did that. Hence the bad zip error.
Also if he has his CM7 SD card still working, he can repair the emmc partitions using the terminal emulator from CM7. All the adb type commands can be run from there.
The boot partition probably needs to be reformated to vfat before it can accept any files from a CWM restore.

[Q]

Hey First post here, but I must first say thank you to all who have shared your knowledge about rooting a nook.
I have a nook color along with a 16gb sdcard.
I really enjoy how through the home interface, you can switch back and forth from nook to android.
Now initially I was plagued with the dreaded 1gb B&N partion, but once again by using instructions found here was able to repartition and get a larger partition for B&N content.
My question is when I download something from the android market (google play) does it download to the nook partion or to the sdcard.
Also is there a setting that I can tell the nook where to download stuff from google play
Another question, being that my nook color is rooted, how do I backup all my settings and apps so that in case it is reset or there is a problem that I can just restore everything.
The reason I ask is because yesterday after rooting and down loading apps and getting the right live wallpaper, i decided to see if through nook color tools I could find a setting for down loading.
I do not know what I pressed but all of sudden the nook started to reset itself and I had to redo everything all over.
Thanks in advance

No, there is no setting for Google Play to install to different places. It downloads the apk file temporarily to /cache (which is shared by both emmc and SD installations) then installs it to the system you are booted to (emmc or SD).
You can backup your stock setup using either CWM or TWRP recovery. You can either use the recovery from emmc if you installed it there, or a bootable recovery SD. Go to my tips thread linked in my signature and I have recoveries there you can use.

So if it installs to emnc that would be the nook color internal storage. Would that be considered the B&N storage area and if so should I use the 5gb partition zip file to get the maximum space available ????

The terminology is confusing. On emmc (internal) there is /data (called internal memory sometimes) that is used for storing the installed apps and settings. And there is /media (sometimes called media or emmc) that is used for storing media data files from apps, like books, pictures and movies and other downloaded files.
The original Nook Colors came partitioned so that it had 1 GB /data and 5 GB /media. The newer Nooks have it reversed, 5 GB data and 1 GB media. That's is what that repartitioning thread you used was all about. And when you say maximum available, it depends on which partition you want to be maximum for what purpose.
When you create a bootable install SD, it has its own /data and /media (called SDCARD). And it uses those when booted to the SD. So installed apps get installed to the /data on the SD.
