First off, I want to thank everyone who spends time developing all of this stuff. I can’t imagine the time and thought that goes into it. I have a few nook tablets that have been sitting around my house. I have 4 kids, and their mother decided that they need brand new tablets, which they all got for Christmas. As usual dad (me) get the hand me down stuff. My daughters all have brand new uggs while I have had the same work shoes for 3 years. That being said, here I am.
I have a NT that I just started to modify. I am a noob, but I know enough to make me dangerous. This is what I got so far, and I need help. I started by using this thread-
http://forum.xda-developers.com/showthread.php?t=2037368.
I rooted my NT with CWM 5.0, ,and then halfway through I was going to put in my second card which I copied the rom & gapps to.It kept saying “no zip files found” They were definatley on the sd, I could read it on my PC. I gave up.
I tried this way & it wouldn’t work for me either http://www.youtube.com/watch?v=s4k2pAZuPBQ I could not get it to boot from the card. In that video, he said to just copy the files onto the card, where as the next link I wrote the image to the SD.
After trying a ton of other stuff, I wrote this file to an SD card. http://iamafanof.wordpress.com/2013...id-4-3-for-nook-tablet-imgsdc-boot-09aug2013/
I got it to work, only after and I jump started it with the usb connection. Also, anytime I want to re-boot I have to do it that way, or it boots right to the nook OS. For me that is just OK, but I want better. I either want to get rid of the nook os, so it only boots into CM (maybe internally), but I am not sure, or get 4.4 running. Last night a goo update started downloading for CM11 zip. I stopped it, because I didn’t want to brick my NT, which luckily has not happened yet.
So to recap, I have a rooted NT (with 5.0 CWM), and I use an SD card for CM 10.2. that only boots via usb. I apologize for the rambling on. Can ultimately get this to run 4.4 with no nook OS from an SD card, or am I better off doing it internally?
Sounds like your NT is one of those units (like mine) that only boots off SD from power-off state and upon insertion of powered USB cable. This behavior will remain regardless of the version of CM on the SD card. If this does not suit you, your only choice is to install CM on emmc (see http://forum.xda-developers.com/showpost.php?p=43326042&postcount=123 for pointers/tips on how to install CM10.x on emmc).
Thanks very much for your reply. I actually got 4.4 up and running very well off of an sd card. I am very new at this, but I am starting to feel comfortable. As soon as I get nightlies figured out and streamlined for updating, I will be much more comfortable.
Thanks again for your reply.

Please help a noob out here. I know the answers are out there, but I am not sure which method is best to use. I am familiar with rooting on my android cellphone, but I am not so sure about the methods used to root the nook tablet. They seem a bit more complicated and I want to make sure I have the correct info well explained.
I would like to know the following:
Where can I find the thread concerning installation of CWM/Rooting and how to back up my tablet before I I do anything else? (I have learned this the hard way, once. Never again will I proceed before backing up so I can restore it when I screw it up)
What is the most stable ROM that has been developed for the tablet so far?
Where can I find the instructions on how to install this ROM so that even an idiot (aka, me) can install this?
Maybe I am just skittish, but I hope you understand.
Thanks in advance!!!
Are you looking to root and run your ROM from SD card? Or would you rather install things to internal?
Thanks for replying. If I rooted and ran ROM from SD card, would that leave the Nook with the ability to run as originally designed if I opted to do that? (by basically removing the SD card and letting the Nook boot normally?) I have never used that option on any of my rooted phones. If so, that is probably the way to go. What do you recommend? I know it is a risk either way, but it sounds like running the ROM from the SD card seems safer.

I just bought a 32GB class 4 SD card tonight, so I am ready.....
This thread might be a good place to get you started. Or at least start thinking about how you want to get set up.
http://forum.xda-developers.com/showthread.php?t=1528625
Using this method by albertwertz allows you to put regular root, CWM, and CM7 (most stable CyanogenMod ROM so far) all on an SD card. He even includes step-by-step videos and does a good job explaining. His YouTube channel contains more videos of various ways to root, too.
If you want everything on your SD card and not have to worry about messing with internal, a method like this is probably your best bet.
Thanks. I tried following Alberts method step by step twice now, and everything seems to go right as far as making the SD card, but when I insert it into my 16GB Nook Tablet, running 1.4.2, and partitioned at BN, it will not reboot. The only way it will reboot is if I take the SD card that I made to root the tablet. It will reboot into normal operation mode. I can't figure out what I am doing wrong. I am really getting frustrated.

Try turning your nook off, insert sd card, then plug it in to charger or usb cord. Some model nooks have to plugged in to boot from sd card.
I finally got it to work. Everything went well. CM7 installed, looked great. When I installed Google Apps. It comes up to the registration screen, but when it tells me to touch the android, the tablet does not register my touch and I can't move past the screen
Finally got everything working. I don't know why I got all worried. Had to reinstall a couple of times and fix permissions. Just like always. I must say I really like CM7 compared to the Nook interface. Nice job Devs! Thanks for everyone's help pointing me in the right direction.

Deleted: decided to read a little more, formulate a question and start a new thread.
Ok, I've been at this 3 whole days now and I DO NOT KNOW what I am not doing right.
I have been following the directions that another member on here has been posting on his blog here.
I have been using the updated files from his blog post here and from this thread here.
Anyway. NO MATTER WHAT I DO, I can not get Cyanoboot to load up. I am using the proper tools to format the SD cards, I am creating the partitions correctly. I am making the SD partition bootable or active. I've done it all and to NO AVAIL. I Can't get it working.
Can anyone who has had success (and apparently there are some) doing this PLEASE give me a few steps. I am not Android Retarded, I understand a lot of this stuff, but I am LOST when it comes to this Nook Tablet and getting this to work. It didn't take me this much time to write my rom for my Razr. It's driving me insane.
I don't want to load CWM onto EMMC or flash a rom onto EMMC because this is my girls Nook and she doesn't want it messed with like that, she just want CM9 to boot from SD and to have the regular Nook software on the internal memory for normal bootups.. I know, I know but that's what I have to work with.
Hey, there's no need for profanity. He just wanted to point out something.
I made a boot able CM9 only card not too long ago, just with the instructions from @succulent's blog. It only took me a few minutes without trouble.
Any idea for where you are getting messed up?

I wish I knew. I've been following the directions to a T. Once, only once it booted to the cyanoboot screen and then went to the two android screen and hung. I rebooted the tablet and it booted right into nook software straight away. It's like I have some freak tab that won't take. I've tried 3 different sd cards too.

Well this certainly sounds like the exact problems users have with faulty SD cards. What brands and classes are you using?
And I think XDA has a pretty good reputation...
I've moved and cleaned this thread leaving only the relevant posts. Please do not use profanity against other members however wrong you feel they are. If you feel something is wrong, do not react just use the report button as that's what it's there for.

Stupid question - have you tried booting with the charging cable plugged in? (Or simply plug in the charging cable when Nook is off.) My nook will only reliably boot anything off SD when plugged in.
Apologies if I missed something obvious.
Just a thought...
Are you sure when you extracted from the ROM zip that the entire file was extracted? I had a problem when I made my CM7 card cause I ran out of memory on my hard drive and only part of the file was unzipped. It took me a while to realize this was the problem and I had the same hang symptoms you describe. Of course I have a really old computer with little hard drive and this is probably unlikely for most, but there you have it. Also something obvious and probably not relevent but r u sure you unzipped the ROM zip files before transferring the ROM files to sd card? I noticed in Succulents instructions that he says "copy" ROM to SD without giving specific instruction to unzip then use tool to transfer to SD card, not drag and drop copy....check your ROM file size, should be over or around 4GB, this might determine if you have full ROM file.
Ok, so noobie mistakes but I made them so just in case!
Also, you have to replace a file in the downloaded ROMS to make the ROMS SD compatible.....could your mistake be in that step?
Just some thoughts...hope you get there soon!

Nook Tablet won't read internal. When plugging in usb message screen from microsoft windows pops up and says You need to format the disk in drive I: before you can use it. Do you want to format it? First thought it was the external card but popped it out. Not the case. I'm on 1.4.0 and running cm7b. I have never updated from 1.4.0. Are there any benefits to updating to 1.4.3? Everything works fine just won't read internal. Before installing I used meghd00t Repartition, Reformat, Restore and Rescue SDcard to go back to stock. (Still rooted apparently). So installed cwm recovery, cm7b and gapps. No problem reading external card just keep getting that jacked up windows message wanting me to format my nook. Thanks for any help or fixes.
If I was you, I wouldn't listen to anything that Windows has to say. Especially about formatting, that would just erase all your data.
What happens when you choose not to format the disk? Nothing at all?

Hey Solar.Plexus,
Everything on the tablet works just fine so far. I've been away from it for 3 or 4 months. Seems like this happened to me before when I bricked it. It seems as though something is kicked out of it somewhere. For instance when going back to stock and going thru the whole sign in it won't let me register with b&n. Don't care about b&n so that's not a problem. Just thought that was why I was never able to get updates and still stuck at 1.40. I just bypass it with the volume up and tapping the screen. Would like to be able to run CM9 on eMMC and CM7 from microSD. But if it doesn't show up not sure what to do. Appears as blank drive letters. Oh well! I remember you now solar. Seems that I posted something months back about the benefits to update and old_fart mentioned something about there is a little box called search. It was a good fun banter. Apparently you got a kick out of it if I remember right. So help me out here please. Are you on 1.4.3?
Appreciate your input my friend.
I actually haven't used stock ROM for a really long time. I currently have CM9 on eMMC and different SD cards with ROMs to use. Let me know what exact dual boot setup you'd like to use and we'll see if we can get it to work out for you.
Who knows, flashing the new ROM might fix the unreadable problem. Regardless, you could probably still use ADB to transfer files to and from your /mnt/media partition.

Sounds like a solid dog deal to me!
Let's try your setup for kicks and see if I can follow along. Not real familiar with Cyanoboot but I know how to push buttons. ADB knowledge a bit limited but somehow manage to figure it out eventually. I'll try not to have too many senior moments with you. I'm ready to crack this puppy open.
Dragging right now so catch up with you later.
Thanks major dude!
Since you already have CWM recovery flashed internally, all you have to do is flash the CM9 ROM and gApps from this post right here to set up your eMMC ROM.
Then to make your CM7 SD ROM, follow the directions under the SD VERSION IMAGE section of this post right here.
After that, you can modify the SD card to use CyanoBoot, the 2nd bootloader. So do this:
1.) Download the CyanoBoot file from this post right here.
2.) Navigate to the first partition (boot partition) of the CM7 SD card you have made.
3.) Replace the old flashing_boot.img with the new flashing_boot.img file you just downloaded.
4.) Done.
Now, anytime you boot up from a completely off state, your NT should* boot from the SD card and go to CyanoBoot, where you can choose which ROM you want to boot into.
*You might need to plug your NT into a wall charger in order to get it to boot from the SD card. Only some NTs require this.
i have read several threads. Installe Ubuntu on a laptop and have come to the conclusion.........I have no business rooting, or anything i hav tried several metods to try and restore my 16gb nt and have been unsuccesful. is there any body out there willing to try and restore it for me. i will pay all shipping and will send it with my 8gb class 10 card. I just want it restored to cm7 or something functional HELL even stock would be great at this point. I do not have the skills to do it myself. It has been bricked for over a month now. This was a device used by all of my family members and now they are all upset with me for ruining it. Will B&N take it back and do a restore? anything ANYTHING PLEASE HELP!
Can't you just start by telling us what you have tried?
Have you for example tried the repart.img card already? If so, what happened?
Edit: I checked you previous posts and see that you tried to get Adam's method going.
Before going through the trouble of sending the Tablet around, try the repart.img
http://raywaldo.com/2012/06/how-to-un-brick-a-nook-tablet-8gb-or-16gb/
In short
1. Download, extract zip and save the repart.img in the same folder as you keep your Winimage
2. Open Winimage from within that folder. (Do not "install" and run, just open from the folder!)
3. Choose the "repart.img"
4. Burn it to the card
5. Boot to the card (inserted in Tablet)and wait for green checkmark
6. Turn off, remove card and Tablet will reboot automatically.
If green checkmark doesn't appear after a few minutes and a red cross appears instead, then you're in trouble and nee to try soimething else. But let's hope it deosn't come to that!
o.k.
Thank You! i have followed these instructions. i even started out with a new 8GB SanDisk microSD and a new usb card reader. i was able to successfully create the card. My 16GB NT does boot to the restore screen but I do have the red x in the corner the whole time. When it finishes, i get a the device will shut down in 5 sec. I have tried the re-boot without the card as well as booting with the power button and the cable. i am waiting for a fresh download of adam's file to try that agin. If that does not work I will move onto celtic's instructions.
FINALLY!
Alright! I have returned to stock. courtesy of the AdamOutlerUbuntuTotalReFlash. The problem is the touch screen doesn't work. I will be attempting to restore to a previous cm back up from here. I owe more than thanks to so many people here. asawi, AdamOutler, Albert Wertz, Celtic, indirect. and all who helped. them. I have learned a bit in a minute and have a long way to go. My 16 GB NT isn't fully restored but, it's closer today than 4 -5 weeks ago!
Woohoo!! And I see you already know how to fix the touch. I'm sure you'll do fine, and I hope you come back and let us know about your success!!
not quite
i am pretty happy with my success so far. and it is all due to this forum. I haven't figured out how to fix the touch yet. I have tried to flash a few different things but no success yet.
Have you tried just running CM10 from sd card? I don't know if you can do that and restore original touch firmware, but it's worth a try!
The Touchscreen app is included, so it "should" work...
Here's a link to and easy-peasy versio:
http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/
Download (first download under "Download", ending with SDC-IMG.RAR), extract and put img-file in your Winimage folder, burn to card, pop into Tablet and boot into sd card.
Open the Touch firmware app and go back to original.
Remove card and rebbot into stock and hopefully all is well now!
Since you don't actually plan to run the Tablet that way you don't have to expand the user partition on the card, just run it as it is!
Edit: FWIW, I went and tried to flash touch formware while running CM10 from sd-card, and it seems to work fine. I then took the card out a and rebooted to my "regular" (internal) CM10 and reflashed the touch firmware back to what it was.
(I have no need for 10 touch right now, so I keep it in original until I do),
So you really should be good to go with Succulent's (Iamafanof) ready-made CM10 (or CM10.1) card images!

I think what I am going to try is re-create and boot from the the AdamOutlerCard and see if that clears up the problem. The nook doesn't seem to recognize the sd card or the format? and will not boot to or from the sd card (CWM) . and then I will move on to Succulent's http://iamafanof.wordpress.com/2012/...r-nook-tablet/ .

At what stage of the recovery did you get this error message, e.g., during the process of initial sign-in to B&N?
o.k. I have achieved boot to SD card using sucullent's iamafanof cm10 image as instructed by asawi. my next goal will be researching and flashing the internals again. i suspect my initial problem resulted from having both cwm and cyanoboot resulting in the two arguing for permissions and rights. Additionally flashing the 10 touch which led to an unresponsive screen, which led me too trying to clear the "wrong" boot or mount and leaving me with only the cwm boot. patience!, clear thinking and help from all of you here got this device back in working order. Again I am extremely grateful for all the help!

Yes! Touch is working. I have not completed the registration for B&N yet. It seems that the updates that they push make it more challenging to root and / or flash to internal. I am just running CM off of an 8GB Class 10 micro SD. I don't want to do the B&N registration yet because I haven't 100% decided to flash to internal. Can the updates still be pushed even thogh I haven't registered? I am considering to keep running of an SD and get a 32GB class 6 card to do that. I would like to have the internal flashed because well let's face it the NT really isn't much to talk about until you. Unlock it's true potential. Question this process which I have followed here the repart and return to stock but running CM off the SD is that considered root?
I'm currently running CM 10.1 from an SD card and it does the same thing as internal boot. All information stored on the SD card with root privileges.
Sv: [Q] PLEASE HELP I GIVE UP and throw myself at the mercy of this community
I can't see any reason not to register your device if possible. You can block updates even if you're running stock as long as you're rooted.
It's more convenient running from internal than from SD, but I can't say I noticed much improvement in performance. Stick to class 4 unless you already have the class 6 lying around.
Be prepared that there might be problems registering after running the Ubuntu restore due to serial number possibly having been wiped.
O.K.

Alrighty then. I guess I will stick with just running off the SD card then. If I can't register then I will probably flash to internal. just curious why stick with class 4? Does the class 4 just run better or more compatible with the NT? How can I can confirm root?
SanDisk class 4 is the SD card most often recomended för NT. Runs fast and well and even devices that are fussy boot easily from it. The way data needs to be read for this kind of use isn't any faster on a higher class.

Is it possible or realistic that I can run a different SD card for different people using the tablet? i.e. using an 8 gig card with games and such for my kids to use. another card for my wife and then a card for myself. My fear is that the kids will eject the card or just not really know what they're doing and do something accidentally? (They are kids after all). My wife doesn't like the fact that I keep changing the configurations. Just overall giving everybody the ability to have the apps and configuration they want without encroaching on somebody else's preferences and hogging up all the space available on the card.

Yes that is possible. Just write the SDC version from iamafanof's page onto separate SD card. Recommended to use at least an 8GB Speed 4 microSD.
The other option is to use the profiles/users feature. It might be only CM10.1 builds that have the User capability. You can set up different accounts for yourself, your kids and your wife.
Ok, first off I want to give a big thanks to digixmax for all his help so far! His quick responses have helped me to stay somewhat calm even though I am extremely frustrated right now. I have tried several different ways to root and boot CWM and CM 10.X onto my NT the last few days and nothing seems to be working. I have tried http://forum.xda-developers.com/showthread.php?t=1439630, http://forum.xda-developers.com/showthread.php?t=2098419, http://iamafanof.wordpress.com/2013/01/09/cm10-1-android-4-2-1-jellybean-sdcard-img-for-nook-tablet-0110/, and http://forum.xda-developers.com/showthread.php?t=1529553 all with no success. i have used different cards, usb cables, and ports. i have used mini tool partition manager, acronis, gparted on ubuntu live, and fedora core that i have dual loaded on my laptop. i have downloaded the same files from different sources making sure to keep them separated in case one image is corrupt. and i have tried the preloaded image and built my own files onto a partitioned card making sure the card was set to FAT32 primary active 0x0C LBA and that boot was flagged. if anyone else has a suggestion i am all ears. im not opposed to just rooting into the eMMC either if someone wants to point me in the direction of a link with CM7.X or newer. the last build that i did on my sdcard looked like this (attachment below )
im not sure if anyone will be able to tell me if i did something wrong, maybe by file size? if more info is needed let me know. thanks in advance!
It's unclear to me what you want to do. Do you want to run CM10.x from sd card or install it internally? Or juts root? "Root" does not mea installing an alternative ROM, so it would be good to know what you're after.
If you want to run from sd Iamafanof's images should work. Personally I prefer his Android 4.1. Try it:

If it's not working, come back with more info on what you actually do and what happens (or doesn't happen).
If trying to install internally that image from Iamafanof can be used as a bootable CWM sd card and you can install CM10.x from there.

It's unclear to me what you want to do. Do you want to run CM10.x from sd card or install it internally? Or juts root? "Root" does not mea installing an alternative ROM, so it would be good to know what you're after.
If you want to run from sd Iamafanof's images should work. Personally I prefer his Android 4.1. Try it:

i was trying to root and rom CMsomething. at this point i dont care how it happens so long as something happens. your right i havent tried booting CM 10 and was actually looking for the version you posted. i read it was a good ver of CM to run on the NT. something that just started happening this morning when i use win32diskimager as admin a box pops up saying File error an error occured while accessing the device. This usually means that something else is accessing the device, please close all applications and try again. Error 1. Incorrect function. not sure what this is about. anyways ill try CM10 from that link and let post back later. thanks!
Make sure any file explorer is closed. That's what usually prompts that error for me. (I insert my card adapter, and the file explorer tries to access it.)

ok that helped some. its now saying write successful again. i tried the first link you gave me for iamafanof and that didnt work either, it still booted straight to stock. i guess im going to try flashing it to the internal memory. i cant believe how much trouble this is giving me, ive never had near this much trouble rooting and flashing with any phone ive ever touched. with the phones i may have been down a day or two trying to find a solution but today is going on day 4 or 5 that i have been trying to do this. time to try an alt route i guess. quick q, if i were to try and downgrade firmware from 1.4.3 do you think that that would help? has anyone tried this?
Having it installed internally is so much more convenient!
But before you give up on booting from sd, have you tried turning the NT off, inserting the sd card, and then plug it in to the charger? That usually gets even troublesome devices to boot from sd.
Edit: Version of stock firmaware makes no difference at all.

ok thanks i was hoping it would make some kind of difference. i have tried booting the NT with the power button, with it off insert sd and then jump start it with my stock cable and other usb cables. i have tried different usb ports on my computer with the cables and still nothing. i have been reading for days and trying everything. ive looked on xda, tabletroms, as well as many other sites that have dev support for the NT and rooting. thats why its so frustrating. im done i think with trying to boot off of the sd card. just going to have to start researching doing it by internal memory. i dont really care either way if i keep the stock software i think i would just be happy with even an early version of froyo or eclair at this point lol. if anyone cares to post links on rooting and installing roms on the eMMC or has any other suggestions about booting from the sd im open for suggestions. thanks guys for your help so far.
You say you've tried different ports on the computer but I told you to connect it to the charger. And also, just to make sure, you do use a class 4 card? SanDisk seems to be the preferred brand.
And I've already posted a link to my instructions.
If you can't boot from SD card any modification will be difficult so you need to get that part sorted.
Edit: And I also take it you are absolutely sure you have a Tablet and not a Color? Model 250A. I ask because it's not uncommon people mix them up.
