No clue what it's running for Recovery though but I'm assuming the CM6 rom comes with one? I'm waiting for a response from the seller.
Now I want to buy a new 32GB Class 6 SDHC card for use with this particular phone. But I've noticed that partitioning the card is an important step during the installation of said ROM? How would I go about partitioning this new card without bricking my phone? I don't need any of the files off the new card since the seller mentioned that he had cleared it. What should I partition the card too? I've heard anywhere from 512MB to 1.5GB?
What are some applications that I should be aware of for this particular ROM? I'm very new to all of this and want to keep the phone running decently well. I've heard something about an application with the ability to run apps off the SD card to preserve memory? Would installing such a program be simple for someone as noobish as me? Or should I keep it simple and just install everything onto the phone?

Ok. Well first off you have a lot of reading to do. Hope you like to read. I can tell you that partitioning your sdcard is done through recovery mode. You need to get in there first. Also cm6 is a rom. It does not come with a recovery. That is totally different. It would be good to know what version you have. I assume amon ra 1.7.0 but it will tell you on the recovery screen. What values you set it to are up to you but you can just leave the values alone when your doing it and it will give you a starting point. The rom will tell you how to save your apps 2 sd. You have to read the first post to find that info out. Good luck and welcome to xda

[Q] root/rom question

now I realize I'll prolly get the lynch mob soon after i post this... being that all the research is over in the dev section, but my question is fairly complicated and i cant seem to find a direct answer from my own reading.
now i have root on my NC and i would love to put a custom recovery/rom on my NC. could any one point me in the right direction to get me started loading a custom recovery? i dont want to run froyo off of an SD card i would love to have it just be a giant version of my phone(I'm sorry if that's asking to much)
i learned and pushed myself to do it a while back on my EVO 4g when i saw there was a rom with wimax capability's and that was my first time rooting anything. I do on the other hand work as a sprint instore service and repair tech. so all of this reading isnt completely lost on me.
and my second question. when i booted my nook back up after i let the battery die, all my setting and apps were gone. any one know anything about it?
thank you for any answer, and I'm very sorry about my spelling and grammar, i know it sucks >.<

i think my biggest confusion/hangup so far has been the custom recovery not sure if i have this right or not but. these are the steps (i think) i need to take.
1. aquire root. [check]
2.custom recovery.[?]
3.custom kernel.[?]
4. custom rom.[?]

So what you want to do is flash a custom rom? You would just download a CWM sd card image. Burn that image to your SD card. Then, grab the rom you want, such as nookie-froyo, or whatever. Copy that zip to the SD card.
Put the SD card into your nook, then reboot. It should boot into CWR and from there you can just flash the zip. The same thing with a custom kernel, just copy the zip onto your CWM sd card, reboot, and flash the zip.
I'm not sure if that is what you are asking, though.

I've actually figured it all out finally. is there any way to see what my CPU is running at?

The speed of your NC can be done by downloading 2 free apps in the market:
Linpack for Android
Quadrant Standard
The Linpack app will tell you how many MFLOPS (Millions of Floating Point Operations Per Second) and Quadrant will give you a score to benchmark for CPU, I/O, and graphics. They will also give you as a reference how you compare to other devices.

So I'm new to Nook. In fact it's still being shipped for the wife, lol. Little that she knows, it's getting nootered before it even gets in her hands.
I've rooted phones and flashed custom ROMs.
From what you're saying above, does CWM reside solely on the SD card? That's different than a mobile phone. So any time we need to install a custom ROM (even the first time), we'd have to boot using the SD Card that has CWM, right? Of course I'd have to root the nook first.
following should really go into a different thread:
So whats the best ROM? So many out there. I just want to be able to use all google apps and market (for kindle app).
Thanks in advance.

You can still install Clockwork from the market and it'll run of the NC without an SD card. I've done it. But for the installation of CM7 (something to do with EXT4? I don't even know what that means...) CWM on an SD was necessary.
On what the best ROM is. Well, looking in the general section subsection here it looks like a lot of people are on rooted stock 1.1. I tried Froyo and it was cool and all, but I missed having the full 8GB of storage on the nook. I haven't tried Honeycomb yet, so no idea on that one. I currently have CM7 nightly 8 on my NC and really like it. I may not have all the storage space still (they're working on it) but it's snappy and sleek.

How to Backup Your Stock Nook Color

Hello Folks (Long time no see ... last time I was on here was for windows phone stuff in 2008)
So I got in on the Nook Color BN ebay deal ($199) plus tax ...and I have been reading quite a bit (but barley scratched the surface on all the reading). So I thought I would ask something simple...
I want to backup my Stock Nook Color ...no changes made to it no nothing ...I did root it with a 2g Mico SD card last night that was super slow and the 2 part restore to factory just takes forever in my book (8 reboots with the factory wipe etc).
So here is my question ...Is there a way to backup the stock BN nook color (1.01 firm ware) with all your settings etc so all you would have to do is load that on an SD card put it in hook up the nook to the computer and your done ...basically a reverse auto-nooter-2.12.25 type of file ? with a step by step instructions
Thanks in advance to any one that responds/read ...sorry Im back to being a Noob ...
If an admin reads this and thinks that this is addressed some place else please let me know where and please delete this thread.

Your options as the way I see it:
1. Use a rooted ROM by booting off the SD card and keep the internal (eMMC stock) in tact.
OR
2. In the development section, there should be a thread on the first page about Dual booting. This may require some workarounds but flashing a second partition with a rooted OS through CWM and keeping the first partition stock might be another option. You may need to do this by booting up CWM through an SD because you might not be able to install CWM if you keep the first partition stock.

Thanks for the reply Eddog4DROID
I was thinking more like I have 2 Micro SD cards (2 8gb class 6 Micro SD) and on SD card "A" I would have the stock as I got it from BN and use the technique where one connects it to the PC and let the SD card do its magic for it going back to stock ...SD card "B" would be used for my normal adroid stuff ...so not only dual booting but for applications pictures etc ...basically all that is fun to do with your full android.
I will check out the dual booting thing in the dev thread as you instructed because I see that as a good option ...hopefully I can have it so if the SD card is in then it boots to the hacked android and if the SD card is not in then it boots to normal standered nook color.
The one thing I am still searching for is the HTC Home type of screen (the old school flipping clock with the current time and weather and the windshiled wipers etc) for the Nook Color to display on the lock screen ...but I plan to look for that in the threads later on.

Can't you just flash back to stock with the posted stock ROM?

That i guess would workd but how do I back up my Own rom ? and is the stock rom actually in ROM ? for some reason (and please correct me if I am wrong on this part) I thought that the Sock "rom" was actually on the SD card.
I am basically wanting to do away with the count to 8 before the rom kicks in ....maybe a cool thing would be to have an application that allows you to auto "flash" to the stock "rom" from a rooted machine ...like it would be an option and once done you would just have to manually reboot with out the SD card ( humm for to look more at the devfourms)

Check out MonsterRoot by IOMonster. Using his image, you can boot CWM from the SD card and backup your configuration to the SD. And of course restore.

CM7 SD card Users - How do you Backup?

Guys,
I have been using a micro SD based CM7.0.2 installation for quite a while now using verygreen's size agnostic SD image on a 16Gb card. I'm going to try 7.0.3 and an OC kernel but I want a backup since this uSD has become my main setup.
I figured I could image the disk win32diskimager (which is what I wrote the original image with) but unfortunately that tool seems to have a limit of 4Gb on the image file. So, what tool are 16Gb+ uSD card user using to back up your SD card? I want it to image the entire card with all partitions that way I can just backup the entire OS and all my data in one shot.
Any tips or pointers appreciated!

I've used win32diskimager multiple times to do just that with 16GB Sandisk cards. The image file in my case is 4.1G (as most of it is empty space anyway)
Every one of my SDs is archived this way whenever I update a new build/kernel.
I've never had more than 3G of files on any card so I can't speak to what happens if the actual content is 4G or greater.

My SD card is about 13 to 14Gb full.... my image is coming out @ exactly 4.0gb, I figured there might be some compression going on, but > 3 to 1 struck me as a little too good, so I'm not trusting win32diskimager.

What OS/File system are you using? I seem to recall FAT32 having a file size limit of 4GB. That could be what you are running into.

I'll take a look. It's a Windows Vista desktop PC so I'd expect HDDs to be formatted NTFS but I haven't explicitly checked.
EDIT: It's NTFS. So that's not the issue. Chokes on more than one computer.

If you can not back up the whole disk image,
how about backing up just all your data files with the USB connection onto your pc?
It seems that each app has their own directory for their data.
Those directories can be copied directly with the USB connection.
This way you can have a new build anytime and still have all your data available.

I'm not sure I understand the concept of backup. What exactly are we backing up? I was under the impression that you can go from one CM7 release to another without losing anything.

It is true that one can update the system with old data intact.
But somebody may feel better if they have their data saved somewhere so that if something happen to the system, they can have their data available to them.
This is espicially true if you are using one device and if you have all your data on that device.

Or if you want to boot multiple OSes/mods and have a stable fall back point, or if you think a curious kid may pop your card out of your nook and lose it, or if the device is lost/stolen, or the new version of the OS your using is not so good/stable after all (happened to me w/ CM7 nightlies), or there's a hardware failure (SD cards are fragile and have a limited life), etc, etc, etc, etc.
Seriously, if you care about your data even in the slightest only an idiot would rely on everything working perfectly all the time, especially on a removable media, much less one that is tiny, and not ultra durable. Not mention the funky partitioning etc under windows, such that it is only readable when in the device and booted.
Anyway, winimage works but it p*sses me off since it's not free. Still dunno why the other tool chokes, it's gotta be some "32 bit" thing.

I could never get win32diskimager to image my 8gb or 32gb SD card it would die at about 90%...I may go for win image. I understand what you are trying to do. I use my 8gb as a default to boot into cm7 recovery when all else fails. Right now i just use titanium backup for my data.

[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.

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.

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:

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

Wait a minute. Alan Moore doesn't live in Scottsdale!
Whatever. Swamp Thing is awesome. You can live wherever you want

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
You'll want to use his directions to load the image found in mrg666's thread here, http://forum.xda-developers.com/showthread.php?t=1344873
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.

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.
