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.

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've heard of an 8 boot reset. How does that work?
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!
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.

Create a new bootable CWM recovery uSD and place one of the files from here on it.
Boot into CWM and flash the file you downloaded.

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

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:

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.

Once again, NEVER format the eMMC short of a catastrophic event, (sometimes referred to in tech circles as a Mountain Dew Event.)

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.
THANK YOU IN ADVANCE FOR ANY HELP! I'm dead new with android and just got a Nook HD+ 32gb (groupon deal $130)
anyway, I've done a ton of reading on here and watched a bunch of youtube vids- i don't know if people use overlapping terminology that means the same things or what.. and also seems like theres a lot of opinions in the forums.
I want basically the full android experience and root access- like i said, never used any android, but i like toying around with these things. BUT i also really want a fully stable platform- don't want constant crashing or it reseting on me.
questions i have-
1)the CWM is the "program" (don't know the correct terminology) that basically gives me the access to back up and install new roms, root, etc? TWRP does the same thing- but i understand you don't use that?
2)If i have a BRAND NEW nook HD+ do i need to back it up before messing with it OR are the "stock rom" zips you provided just that?
2) with the SD card image, do i need to put a specific image on the specified sd card. i.e. 4gb SD gets a 4gb image? or is the image universal to whatever size SD card i get?
2a) What problems am i going to run into using my mac to make the SD card, if any? what program do i need to use?
4) when you back up through CWM where does it save it? to the SD card?
4a) this is where i was confused about the image, reading into some of the posts it led me to think the image file took up the entirety of the
SD card.
4b)So in the future i could just boot from the SD card and would have the option to flash the stock rom back on the HD+ if desired? and/or
go back to CM?
5) what is DUALBOOTING? and NANDROID? how do they tie into CWM and CM10. very confused about this.
6) any disadvantage to flashing the EMMC vs booting from SD card every time? I THINK i want to flash the emmc, i don't want to be tied to booting from the SD card everytime- if I'm understanding that correctly.
7)what is this "trim" lag problem? couldn't really figure out what people were talking about.
thanks a ton for any help you can give me- I'm sure you receive a lot of questions!

CWM (ClockworkMod) is a recovery program that allows you to do just what you said. TWRP is also a recovery, but uses the touch screen instead of hardware keys to control it.

You can either use the CWM backup tool to return your device to stock (including any data you have already created, like registration) or the plain stock zips I have will also return you to stock, but the way it was when you got it new before registering.
3) with the SD card image, do i need to put a specific image on the specified sd card. i.e. 4gb SD gets a 4gb image? or is the image universal to whatever size SD card i get?

Since you have a Mac, the best way to do it is the new procedure without burning an image. Since I don't have a Mac, I don't know the exact programs to use. I think SDFormatter comes in a Mac version. And I know there are lots of mac partitioning programs to set the first partition active. And using the procedure does use all of the SD, so it is best to use a relatively small one, 2-4GB.

It saves it either to the SD card or internal memory, you choose.
Yes it uses all of the SD if you use the new procedure. But you need that if you choose to backup to SD. A backup takes about 1.5GB.
And yes, save the SD for future use, like restoring backups or installing new ROMs.
5) what is DUALBOOTING? and NANDROID? how do they tie into CWM and CM10. very confused about this.

Dual booting means having one operating system on internal memory (also called emmc for Embedded MultiMedia Card) and one installed to a bootable SD. Most people that dual boot have stock on internal and CM on SD. They are separate and independent from each other.
Nandroid just means internal memory. So a nandroid backup means backing up whatever you have on internal memory.
6) any disadvantage to flashing the EMMC vs booting from SD card every time? I THINK i want to flash the emmc, i don't want to be tied to booting from the SD card everytime- if I'm understanding that correctly.

The only advantage to booting to CM on SD is it leaves internal memory untouched for warranty reasons. The disadvantage is it runs slower and is less stable.
7)what is this "trim" lag problem? couldn't really figure out what people were talking about.

LAG is a complex issue to explain. If you are used to hard drives getting fragmented and slowing down your system, LAG is similar but a different mechanism with solid state flash drives. TRIM is a process to undo what causes LAG. But some of the solid state chips in these devices have a bug and when TRIM is run, it bricks the chip, making it unusable.
