[Q] Stuck in CWM loop - Barnes & Noble Nook Tablet

Hi,
I have a Nook Tablet in version 1.4.1 reset it back to 1.4.0, root it, tried to put cm9 in it...messed up royally, format a whole bunch of things that I shouldn't.
Now it's stuck in CWM v5.5.0.4
Tried just about everything, but can't get out. can't access adb, not very familiar with it anyway...but downloaded sdk, jkd, etc...but can't see device...tried recovery image also...doesn't work.
Is there any method aside from adb method? Is there an SD method...think I messed up the partitions or whatever...
tried this method:
http://forum.xda-developers.com/showthread.php?t=1555832
but doesn't work...
again can't see devices in adb...tried this & other methods...nothing..
http://forum.xda-developers.com/showthread.php?t=1363652
please help...
I actually have 2 Nook Tablets...one for my kids & another I'll give to a nun friend...1 is correctly rooted & has cm9...can I image one & flash it on another? If so, how?
Thank you & God bless

Have you tried making a bootable CM7 or CWM microSD card?

I have a recovery.img...tried that didn't work
have boot.img tried that...CWM microSD
tried to flash SD_ROOT_NT16gbV4_6 onto microSD, but after that can't add anything else to it...the directions to partition microSD is somewhat confusing to me...don't quite know what to do or where to put boot file, etc...after I partitioned it...any advice is greatly appreciated...

"format a whole bunch of things that I shouldn't." BAD IDEA. Can you tell us what exactly you formatted?
Is always good to have adb working so you should troubleshoot it. In my FAQ there is a link for a how-to i made to install and use adb tool, run the runmefirst.bat from the package i provide is a must.
As an alternative (to non use of adb, etc tools) you can use Adam's total wipe (sdcard), which has been fixed by Adam to not affect serial ID's and MAC address from ROM partition.

I formatted....
bootdata, cache, data, emmc, rom, system, sd-ext....everything with the format in front of it...I did it...I know...not smart...
did the acclaim_update...doesn't work...CWM seems to be working...but just can't install acclaim_update or SD_ROOT_NT16gbV4_6...again can't access adb at all

What does it say when in CWM when you try to flash something?

they won't work because you formatted most of your partitions, use Adam's total wipe as i said before or soshite unbrick method but for that one you need adb working.

If he has cwm he has adb.
Just guide him to install correct drivers for it.

Well, I download the adam's image for windows, but in CWM cannot mount sd card...oddly, when I plug it into my computer, it sees the nook but cannot start adb...tried methods to recognize usb, but can't...
please advise....thank you

Go here, https://github.com/succulent/acclaim_recovery_sdcard
Make a new recovery card from the instruction. Forget your old recovery card.
Install these two,
flash-restore-stock.zip (use it to restore partition 1-6)
flash_stock_1.4.2.zip (use it to restore to stock 1.4.2)
Then install whatever rom you want after.

Thank you, thank you...used only this flash-restore-stock.zip & was able to find my way back... thanks a lot...my friend who is a nun will enjoy this when she goes to Ghana on her mission...she wanted this instead of carrying loads of spiritual books...thanks again... & God bless

I second that succulent with your post I was able to find my way back after flash-restore-stock.zip. My issue was Nook kept on booting CWM. Now I have to figure out how to boot CWM via USB again to flash stock rom. For now it takes me up to B&N member setup page, but only shows error when I enter info

Okay I wiped my internal emmc, so there is no OS. When I turn it on I get B&N stock setup menu. Than after account sign in it gives me error message with device info.
I can boot on SD CWM, but when I try to flash any zip it aborts and also I can't seem to find the right CWM SD that leaves me enough room to copy the OS.zip on the SD.

Fix: How to fix "broken recovery" NT's

First, you need to be sure you install the sdcard version of the recovery, otherwise you won't be able to do this. (You need to goto this thread to install the sdcard version and follow instructions.
First of all, make sure your drivers are setup properly as this is a windows script to fix everything since you can only fix it from a computer. (I CANNOT EMPHASIZE THAT ENOUGH!)
Then you just download this zip, it check's md5 sum on the image before flashing so no worries, and then it flashes. It will reboot when it's finished.
I am in NO way responsible should anything happen, it was your fault for not checking the app's md5 in the first place so if this works for you, openly admit that you could have been better with handling the app's flashing. <-- Required.
I'm having a seperate thread so I can actively update this with anything that may arise since it would make my app's thread cluttered.
Read the whole thread or enjoy a broken Ntab, it's your choice.
Just wanted to say thanks for the dedication to those of us not smart enough to figure things out on our own.
Sent from my BNTV250 using Tapatalk
is this for those nt cannot use sd card recovery or 8 times boot break to restore the originally rom?
Dumb Question
Total noob question. What do you mean by drivers set up properly? I want to try this, but I do not want to screw up again, and I just want to be totally sure I understand this properly. Thanks.

Means that you must have your nook drivers installed and working, if you ever rooted then you should have your drivers working properly.
~ Veronica
Can't get this to work
I have verified that I have the proper drivers (thanks Veronica). I unzip the fix and run the batch file, but the window closes almost instantly. I am using an XP machine, because of installing the drivers when I rooted. I can not for the life of me figure why it wont run. I am booted into the sd card version of CWM. Do I need to mount it some way or just at the home CWM recovery screen. I have been looking for help without asking and bothering, but can't figure it out. Not a noob but totally confused. Any help would be appreciated. Thanks.
Oops! I managed to set the wrong error levels on it, I meant to do 0 and 1, I instead did 1 and 2. Anyway, uploading now.
Still no go.
I got the batch file to run but it does not finish. It starts the Deamon successfully, and it just stays at Deamon Started Succesfully. It has been there for about 45 minutes. Should I wait or can I kill it and start over. Thanks again.
Kill it reboot your machine and start over
Sent from XDA premium using my Nook Tablet
No Go
Thanks Veronica, but the reboot still does the same thing. I just started the Nook&Zergy and the device shows up so I know the drivers are proper, it just stays stuck in Deamon Started Successfully for the fix. I am out of ideas, I fear I have just bricked my first device. I have doing this since the G1, this is sad.
No no, just do:
adb push cwm_internal.img /sdcard/cwm_internal.img
adb shell
then type:
dd if=/sdcard/cwm_internal.img of=/dev/block/mmcblk0p3
First off great work Indirect. This is exactly what I was hoping that image creator would be used for, just working on other things and got preoccupied. I think you might have to do some explaining though.
One thing to note though is that CWM should not be used for any other then rooting your device. As it stands right now there is no reason to flash it to an internal partition, you will only risk messing something up, as it has no gains.
Overview:​In the Nook Tablet world there is a locked bootloader, which requires that there be a Secure Chain from u-boot, to the recovery. With the exploit that bauwks discovered and designed, we are able to flash custom recoveries on to the device. However a recovery must be packed.
Packing Structure:​​There are two ways that we have been able to go about getting around the boot loader, the internal method requires that we use the second U-Boot, with a 256k buffer and then attache the recovery after the buffer.
(0-m bytes) ------> (m-256k bytes) ------> (256k-n bytes)
Bauwks ntBoot Buffer nemiths CWM
The trick is that that 256kth byte must contain the header for the CWM, and this is vital. If that is lost, or something on Bauwks didnt get flashed right, you will enter a boot loop.
FAQ:​
What Is a 'broken recovery' NT?
A broken recovery Nook Tablet is one where either the NT's internal recovery structure was not writen correctly or one where the NT's internal recovery structure is missing bauwks boot.
How can I tell if I have a 'broken recovery'?
Assuming you have not messed with any other partitions if you do either the N + pwr method, or the 8 false boots, you should see it open the BN recovery. If your device constantly turns on and off after one of these two methods, then you have a broken recovery partition.
My Nook just continues to boot into the recovery whats this?
Aha now that is not a 'broken recovery' and is actually quite fixable. In the nook Tablet there are two files that relate to the booting structure, aka the selection of where to boot from. These lie on a partition called bootdata, and are named BCB and BootCnt. If you are running stock on your internal partition, just let the stock recovery run, and it will solve your problem. If you are running CWM, you will have to use the following commands,
Code:
adb shell mount -t vfat /dev/block/mmcblk0p6 /data
adb shell dd if=/dev/zero of=/data/BCB bs=1 count=1088
adb shell dd if=/dev/zero of=/data/BootCnt bs=1 count=1
adb reboot
Aaa this is confusing can't I just put the stock recovery on my NT?
Sure. Hopefully indirect will make a script soon, or I will make one tonight that will put the default recovery img back. If you are feeling lucky you can do the following while on CMW.
NOTE: I AM NOT RESPONSIBLE FOR ANY DAMAGES YOU CAUSE TO YOUR DEVICE. One false move and you will brick your device. HIGHLY UNRECOMMENDED
Code:
adb push recovery.img /data (this is the recovery from the 1.4.0 or 1.4.1 update zip)
adb dd if=/data/recovery.img /dev/block/mmcblk0p3 (THIS LINE IS [COLOR="Red"]EXTREMELY DANGEROUS[/COLOR]. It should only be done as a last resort, and you should only do it if you are willing to take full responsibility.)
Dead End.
I am going to start from the beginning. I flashed CWM using this app and the hit reboot into recovery from the app as well. Went to the cardboard box. I can reboot into CWM using the sd card method but can get no further. I have been trying the fix for two days and cant get it to work. Indirect gave me some ADB commands but I cant get ADB to work either. I have been on this for 2 days and cannot get it going. I really do not know what else to do. I am not a Noob and i know I have the proper drivers, the fix gets stuck though, and with the tablet in CWM from the sd card I just cant get ADB to work. I do not know if maybe because of usb debugging not being checked off, but again I can not boot up to Android, just to recovery from sd card. If I take out the sd card with CWM it boots to the cardboard box, then to black screen, and there it stays. I checked the thread for the app and people are still having this problem. I really do not know what to do. I have followed every instruction I have found or has been given to me, to the t, nothing.
UPDATE - I deleted the sdk and everything that had to do with Android from my pc. Reinstalled drivers using the method in the root thread that is pinned. I ran NOOK&ZURGY just to see my device appear in list of adb devices, which it did. It gave me my serial and it said recovery. I then redownloaded the sdk and did not download the Drivers from SDK manager. I am not sure but that seems to be the key here, to get rid of google drivers that can be downloaded from SDK manager. I then opened a command prompt, adb devices and bam there it was. I used the commands posted by LogLud above my post under "My nook just continues to boot into the recovery, what is this?". ADB Reboot and ****ing worked. THANKS TO INDIRECT, LOGLUD, and LAVERO.BURGOS. Your patience and help is greatly appreciated. I have never really asked for this much help before on XDA, and you guys were on the money, Thank You, Thank You, Thank You. Please PM me so that I can get you guys and girls beers. I will try to figure out how on my own anyways, but you guys deserve a contribution for taking the time out of your day to help me and others. Anyone with this issue and is having problems fixing, please post here or shoot me a PM and I will gladly give you all I can. Thank you again to all and happy flashing.

Oh well you should had started your first post by saying im using SDK and you will have it fixed faster. SDK is not needed in windows, leave that for devs all the necessary stuff that you needed to root is provided in indirects permanent root thread including drivers.

I used Indirects app to install CWM, it seemed to work fine, but when I tried to boot into CWM it flashes the picture of the box, then shuts off. I tried using this method to fix it, but the same thing happens.
What am I doing wrong? Please help. I'd hate to have bricked my nook.

Sorry if I was not clear. Here is the entire process:
1. I have a rooted Nook Tablet.
2. I installed Indirect's One Click App to install CWM
3. I used that app to install CWM.
4. I attempted to boot into CWM, but it flashes the box and then shuts off
5. I came to this thread and began following the instructions to fix it, but the fist set of instructions "First, you need to be sure you install the sdcard version of the recovery, otherwise you won't be able to do this.(You need to goto this thread to install the sdcard version and follow instructions.)
6. I followed those instructions, but I still get the box image then shut down.
7. I can't boot normally or into CWM.
Let me know if you need any other information and I greatly appreciate your help.
What I really need to know is how to create the CWM sdcard on a mac. i.e. I don't have a linux machine with gparted and I can't figure out how to get something like Disk Utility to enable boot and lda flags.
Thanks!
bootable sd card with osx
Lehite, I was having the same problem, i.e. disk utility in osx couldn't do the job for me. I ended up using this method.
Download the “size agnostic” CM7 SD card installer image (v1.3 in my case), then write it to your microSD following the instructions on the before mentioned page. The writing takes a little bit without terminal telling you the progress, after 1-2 minutes it should be done.
After succesfully writing the image to your SD card copy the files from Goncezilla's SD Boot thread (here) to your SD card overwriting files if necessary and follow his further instructions.
On a reboot with the boot SD inside your nook you should get to the CWM menu after seeing the cardboard box. good luck!
I myself am also stuck at the black screen after the box and need to figure out how to get the ADB working on osx to be able to do Loglud's commands...
UPDATE: to get ADB working on osx I used this method. Since I'm not a developer I didn't download the whole SDK package from google but rather just the ADB tools from here.
I then connected the Nook to the mac while in CWM, checked if it was properly recognized but typing adb devices, and applied Loglud's adb commands. BAM! worked! Am back in android Many thanks to all for directions, especially Loglud.
Now a question to Indirect, I downloaded your package just today, while using it it verified the MD5 positively and continued flashing. Why did I get the black screen, and not the CWM?
cheers

Nook won`t boot after cwm failed to install img

Nook tablet 8gb won`t boot after cwm failed to install cm7 img. Cwm version 5.5.0.4, just hangs on me everynow and then. I managed to boot from sd card created with cm7, i can boot on sd, but one large piece of my sd card is not accesable, i can not create partition or increase size of the first partition created by cm7 img. Also i`m trying to use adb to run "parted" script, but lt just wont let me, permission denied, i`ve tried chmod 777 sdcard, and chown root it too...
Ok...because i`m so really tired of f..ing around this that nook and spended too much time on it, instead of being with my family, all i want is to make that big chunk of sd card partitioned and accessable, so i can wath movies and read books, thats all i want after 3 days of torcher...

I have put a procedure for 8GB model, read it up. just try to flash stock recovery then use the stock 1.4.2 update .zip to unbrick and go back to purely stock. Do not attempt to flash CWM until there is a fully working version for 8GB NT model, anyways you can't flash any other ROM so...

partition tool questions, installing to the internal device...questions from the noob

Thanks everyone, i bought a 16bg nook tablet (for the 1gb ram) and booted from the SD successfully. but now have a couple more questions....
1) partitioning, i get, its easy in gparted or the windows manager, but for the life of me i do not see a quick guide on how to partition *correctly*. i see 5 partitions on the sd card, and the guide says to expand 4... but it wont let me. i have not tried gparted yet, but i assume if i cant expanded it now (in windows) that i am doing something wrong and will just bork it up in gparted. so.... any links to working partition guides ?
fyi, the partition tool in cm7 in the "cm7 settings" only gave me the option of "512 megs"... so not sure.. but i think the installer made the wrong partition sizes ? dunno... im new and assuming alot based on alot of windows crap and limited linux interactions...
2) installing TOO the device itself: in the one guide above it does not mention rooting, so i assume when you boot to cm7 off a sd, and then go to "install image" that it will root, lay down the new image and all is well... am i correct in that assumption?
3) recovery, i know i will kill the install eventually. im the kind of guy to tinkers and has to re-install windows and backtrack on a regular basis. what i have not seen is how to restore to factory. is it something like my htc glacier? like this link implies ? http://nooktalk.net/nook-faq/nookco...-how-do-i-do-a-hard-reset-system-restore.html
4) if i unplug the usb cable.... i no longer boot into cm7 on the stick... is there a way to not have this happen aside from writing over the image ?
thank you all for your patience!

[HOW TO] Root/Run from sd/Install CM10

I am now making post that there really shouldn't be any need for, because all that's in here is already covered elsewhere. 100% Apparently not easy enough to find for newcomers, so I'm making an attempt to help info collection.
NOTHING here is my work! All I’ve done is trying to make easy to follow instructions to other people’s hard work. Those people deserve your thanks, not me!
I’m a newbie myself and that’s why I can say that this really is very easy! If I can do it without problems, so can you! I try not to chat away too much in the instructions. Make regular searches, here or Google for more info. I found it, so surely you can too! Any questions? Well, being a noob myself I probably can't answer. Google is a very good friend of mine though...

You need to know how to burn an sd image. Separate instructions to that after the other instructions if you don’t.
Step 1: Establish what it is you want to do! Choose A, B or C
A: You do not want to touch the internals of your NT but want to try CM10 anyway
B: You want to stay in the BN environment but would like to be able to install apps from elsewhere (for example Google Play Store)
C: You want to get rid of BN and install CM10 instead.
A: Run CM10 from sd card – no root required
This should work on 8GB Tablet as well as 16GB
When you boot into the card you’re running Android ICS. Remove the card and you’ll boot to internal BN operating system. (Or keep the card in, boot to Cyanoboot Menu and choose “internal boot”)
Ready-made card image download links to be found here: http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/
It’s a large download (around 500 MB), but it is a ready-made sd card image. As it says in the instructions there, you’ll more than likely want to expand the user partition to take full advantage of the card, but that’s covered in his instructions.
There are other, more manual ways to make these cards as well. Also covered both in that blog and here at XDA! Go search!
B: Root the Tablet
This works on both 8GB and 16 GB Tablet.
“Rooting” is like unlocking your device, giving you access and control over it. You’re still running BN operating system though. Several excellent root guides here on XDA.
For example: http://forum.xda-developers.com/showthread.php?t=1488035
Or http://forum.xda-developers.com/showthread.php?p=21275927#post21275927
The first one (Brian’s) require a 2 GB card the other one (Albert’s) just needs a very small card. (I think 128 MB would do, but I don’t have any that small to try)
Both give good instructions in their topics.
Both install gApps.
If you want to block OTA updates from BN, go to Play Store and find NT Hidden Settings. Even if it got installed with the root it’s probably not latest version and doesn’t have the Block OTA function.
C: Installing CM10 internally
***8GB owners must make sure to use ROM that works with their device!***
Since I’m a noob I look for easy way, and this is very easy and needs very little know-how!
***Warning! CWM is a very powerful tool. Do not "wander around" and "experiment" with stuff without doing proper research! Seriously! DON'T!***
1. You need a bootable CWM card. Instead of making my own I use Albert's root image from B (above) because this image includes CWM 5.x.x. I use this to flash a higher version CWM internally. I erase the zip files from the card to make room for a flashable CWM 6.x.x
2. Find a flashable CWM 6.x.x I found mine through http://forum.xda-developers.com/showthread.php?t=1640958
I use the one named "flash_cm9-10_cwm v6...." Download and copy to your sd card.
3. Boot into the sd-card and it should take you to CWM 5.x.x. environment.
I guess a backup of you current system would be a good thing (even though I admit to skipping that myself). To backup you'll probably need another card if you're using "The Albert Card" now, because I doubt it's enough room on that.
You navigate with the volume rocker, go back to previous menu with “power” and confirm choices with “n”
Choose “install zip from card” – “choose zip from card” – your CWM zip
See warning above!
4. Power off and prepare your sd card for ROM flashing. (If you’re working with just one card you will need to format it with SD Format or similar to get it back to full capacity.) Put your CM10 ROM zip and the appropriate gApps zip on the card.( It doesn’t matter if there’s other stuff on the card, so you don’t have to format it because of that!). I will not link to a specific ROM. Make your own choice but be sure it works for your model and also make sure you use the right gApps!
5. Reboot into Cyanoboot. This took me a couple of attempts to get right.
From powered down device, press power and right after that press and hold "n", You should boot into Cyanoboot and get the boot menu. Choose "Internal recovery" and you should get into new CWM
6. I don’t know how much clearing is needed, but I prefer to clear pretty much everything to make sure of a clean install. Cache and Dalvik I always clear.
***DO NOT format anything unless you knwo what you're doing! *** (See Satan's posts below)
7. Flash ROM and gApps same way as you flashed the CWM 6.x.x (install zip from card – choose zip from card) reboot and go!
How to burn an sd-image:
I use Win32Diskimager. Download link in Albert’s root topic (and numerous other places!!)
Unzip into a folder.
(I also copy my various img files to that folder to have them easily available)
No need to install, just run by doubleclicking the EXE in the folder.
Make sure the device letter really is your sd card.
Click on the blue folder and navigate to your img file, choose it and “write”.
It will take some time if it’s a large img, but that’s what the progress bar is there for, isn’t it?!
Nice work ,
But you should add 'do not format any partition ' warning. Android users coming from other devices might do this by default during flashing rom.
Almost every one with bricked tablets has tried formatting partitions.

Thanks Satan! I did not know that! Will do!

Veronica had made sticky thread to reduce number of bricked tablets, but looks like some people missed it.
To be more specific,
Do not format rom, boot, bootdata, and factory.

Do not format especially the rom partition and, most critically, the factory partition which respectively contain a set of small files with device-specific unique data (not only Serial No. but also MAC address, public/private key certificates, etc.) and the backup archive copy of the same data files (/factory/romdata.zip).
Unfortunately, I've seen some "unbricking" tools (including some that are very frequently cited/recommended on these NT forums) reformat/zero-out and flash over these 2 partitions. The end result being, even in the event the "bricked" NT gets "restored to stock", depending on the specific tool used it could be carrying device-specific data of someone else's (e.g., tool developer's) NT.
EXACTLY!

Help
Im trying to single boot CM10 from sd card without touching nook os. I am using guide (CM10.0 Jellybean SDCard IMG for Nook Tablet (12/31) FINAL)
I have tried for hours using different methods also and cant even get it to boot to CM, no CM logo at all. I have a BNTV250 NT on 1.4.3. I have tried multiple sd cards, I am using a Sandisk 8gb class 6.
In a nutshell all I should have to do is
-Format the card with SD formatter,
-Extract the (Extract cm10_xxxxxx_sd_hd.img from cm10_xxxxxx_sd_hd.7z/rar)
-Use Winimage to write the image to the SD card, correct??
The Nook still refuses to boot into Cyanogen, just boots up normal every time!
same with every procedure i have tried,
Any pointers????
Have you tried putting the sd-catd in the powered down Tablet and then insert the charger cable, connected to the charger?
Many Tablets have difficulties booting into sd other ways,

Any clue of how to get rid of booting that way? I'm not always with a USB cable witj me.

I've never had to do it that way myself so I really don't know. You could try pressing the "n" buttons right after the power button and holding it for a few seconds.
Actually not being able to boot into SD card easily is the reason some install internally instead.

Tried doping that with no luck. After 8 or 10 attempts magically boots todo cm. Thanks.

Alright, just got cwm 6.x installed and now ready to install rom, just wanting to verify that I should still "wipe data/factory reset" and "wipe cache partition"? That is different from "formatting" correct? I don't wanna brick this thing without confirmation. Thanks for the awesome guide!
edit: Ignore the wipe question, found it, thank again for the guide, I will let you know how the install goes!

[Q] NT 16GB always boot to Recovery Mode only

Hello,
I've searched many topics but still didn't work
My NT 16GB worked good till today. Today I want to flash a new ROM (CM10.1 rc5).
I though I made a mistake from here: from ROM Manager, I flashed the CWM to 6.0, but I might flash with Nook Color version :crying: and from this time, my NT is ALWAYS boot into recovery mode.
- I tried press Power and N button or 8 times fail reboots but it still boot into recovery
- I tried flash new ROM from sd card, and the status is shown Installing Update.... and then it shown Install from sd card completed!!! There was no any notification more (as usual). And after "completed" by this way, reboot and still went into recovery mode again
- I also tried flash new cwm version 6.0.x, wipe data, format system, data,.... and flash ROM again from sdcard but still didnt work.
- I also tried reset to factory default http://forum.xda-developers.com/showthread.php?t=1663836 but it still boot into CWM again and again.
- and follow many topics on google search but still no luck
please anyone can give me a hint, let me see the way to escape the recovery screen :crying::crying: thank you so much!
I want to flash a new ROM, a fresh tablet to make a gift for my dad on father's day, but it is brick :crying::crying::crying:
I think using ROM manager to flash recovery may not work with our device (I may be wrong) but we don't have an official build of CWM.
Regardless.... Do you have adb set up? If so, does it recognize your nt?

Ok, no big deal yet. Lets try the following.
First you are going to need an extra SD card, one greater than 2G. Go to this thread http://forum.xda-developers.com/showpost.php?p=21895025&postcount=14 and follow the instructions. This will give you the files and show you how to make a CWM bootable SD card (ignore all the steps about rooting your device in this thread for now). Note that this will repartition your SD card, so you will not be able to use is for much else unless you re-repartition it yourself.
To tell if this is successful or not, note the version of CWM you are now booting into, I am guessing it will be 6.0.3.1 (newest version) since you tried getting this from Rom Manager. If it is booting from SD card it should show up as version 5.0.x.x (I don't remember the exact version but it is older).
If you got it to boot from SD card then lets pull an updated version of CWM from this site http://goo.im/devs/succulent/acclaim/recovery The older version of CWM may not work well with CM10.1. try CWM 6.0.2.9, make sure you download the flashable CWM zip and not the image file.
OK now you will need to put this zip file onto your SD card - there should be just enough room left for it, or you could put it onto a 2nd SD card (easier) Note: while in recovery you can take the bootable SD card out of your NT. Go ahead and flash the CWM zip. You should now have a working recovery. At this point try flashing a ROM of your choice.
Good Luck

Hello DavDic,
Thank you for your help,
I follow your link and I success to boot from SD card, and CWM version is 5.0.5, then I success install the update.zip too, unfortunately after removing the sd card and reboot, it still boot to CWM version 6.0.2.9 - this is the version that I flash from ROM Manager before my NT is bricked (I flashed wrong device when I choose Nook Color in Rom Manager)
So I try to reboot again from sdcard, cwm version 5.0.5, then flash new CM10.1 ROM, and reboot and still go to CWM 6.0.2.9
and again, I boot from sdcard, cwm version 5.0.5, flash to new cwm version 6.0.2.9, flash new ROM and still boot to CWM screen
So, I can create and boot from a Sdcard, But can not boot to OS, always go to cwm 6.0.2.9 screen (that I think the wrong file since I flash from Nook Color file ). Thank you!

I think your problem most likely has to do with BCB/BootCnt not getting reset properly, as described at http://forum.xda-developers.com/showpost.php?p=21381141&postcount=1.
If so, the easiest way of resetting these files is to flash Succulent's flashable_fix_bootloop.zip at his repo http://goo.im/devs/succulent/acclaim/recovery.

You need to try and get an adb connection. I assume you are running Windows, if not............
But, what happens when you plug your NT into your computer. Do either of your drives (Internal/external SD) show up in my computer?

You should have an adb connection then. Before you jump into the total wipe attempt, try getting an adb connection. Use this first and see if it works http://forum.xda-developers.com/showpost.php?p=36650082&postcount=171
You will need the driver files for this though, let me know if you don't have them.

Well this is a start at least.
I think Digixmax may be on to something though.
@digixmax, I am at work and don't have an NT in front of me, do you remember which partition the recovery is in. I wanted OP to see if those two files were even there. He may have gotten rid of them completely inadvertently.

These two files are in the /bootdata partition (see http://forum.xda-developers.com/showpost.php?p=37515697&postcount=31 for a list of the NT partitions and their content).
But if OP's flashing Succulent's flashable_fix_bootloop.zip (which basically re-install a fresh copy of these two files) didn't fix the problem then he might have wiped out some other critical components of the system.
I follow Adam's guide, unbrick my NT, and then flash new CM10.1 ROM perfectly.
Thank you again DavDoc and digixmax for helping me so much! :good:
Glad you got it working again
