[HOW-TO] Install CWM [VERIFIED][Update 1/22/2012] - Barnes & Noble Nook Tablet

I'm working on this thread to show others how I've gotten CWM running off of my NT.
This will be broken out into 2 sections: SDCard Execution and Internal Installation. I've verified that backup and restore works using both of these methods.
First I would like to thank Bauwks and Nemith who have developed the u-boot crack and recovery.img used in this process. Here are some of the threads that I used for this process:
http://forum.xda-developers.com/showthread.php?t=1440645 - Nemith's CWM recovery.img
http://forum.xda-developers.com/showthread.php?t=1440438 - Next steps and Bauwk's internal image build process
METHOD 1 - SDCARD :
1. Setup SDCard
Using a new SDCard (not one you have info stored on) make a new MSDOS partition table and add a 50 MB FAT32 partition as the first primary partition. Then make sure you enable to boot and lda flags.
Any SDCARD larger than 50 MB should work but I used an extra 2GB laying around. You can add other partitions to the card if you want, but it is not necessary to allocate the entire card. Any added partitions would need to be manually mounted on your Nook anyway.
I used GParted on my Ubuntu machine to do this but any formating tool should work.
2. Copy Files onto SDCard
You can grab the files I used here:
http://www.mediafire.com/?dr6bqau194389te
Just UnZip the files directly to the root of the boot partition you created above (make sure flashing_boot.img, u-boot.bin, and boot.img are on the root not the folder SDCARD)
3. Insert SDCARD into NT
Now, with your NT powered off, eject the SDCARD you just created from your computer and insert it into the tablet. Then just turn it on and VOLA! You should now be in CWM!
You can then insert another (larger, preferably 16 GB +) SDCard and do a full backup.
METHOD 2 - Internal Installation:
ADB REQUIRED!!!!!
Make Sure you have Method 1 working before trying this! It is a good idea to have already backed up your device before proceeding.
Update 1/19/2012: I've modified the internal recovery.img to automatically execute the code in Step 4 which seems to have finally fixed the boot-loop. Now you can use CWM internally without having to be around your computer! Please see Pg 7 for details on how I fixed this issue.
Update 1/22/2012: I'm removing the warnings since this method seem to be verified by a lot of different sources. It looks like Indirect beat me too an APK so please see his thread if you want an easier way to install this:

1. Get Recovery Image
You can use the image I built from Buawks/Nemith source.
http://www.mediafire.com/download.php?yodxftopf5qckgo
The original image I created (with boot-loop) can be found here but is considered obsolete. I'm leaving it here while the new image is tested:
http://www.mediafire.com/?k5azwo6modab9j9
2. Copy Recovery Image to SDCard
You can either push using
Code:
adb push /path/to/irrecovery2.img /mnt/sdcard/irrecovery.img
or just Copy/Paste from a computer.
I recommend using the SDCard but really you can push this file anywhere you can access it from the Nook.
3. Upload Recovery Image to Recovery Partition
Just follow these adb commands exactly!
Code:
adb shell
su
dd if=/mnt/sdcard/irrecovery.img of=/dev/block/mmcblk0p3
Done! You will get into a boot-loop if/when you go into CWM.
You should now be able to fully backup and restore! To get into CWM either adb
Code:
su
Code:
reboot recovery
or power on the device while holding down N+Power (you may need to unplug usb and/or let go of the power button after boot if device keeps turning off).
NOTE: If you are getting a "Error mounting /sdcard" when using backup/restore you just need to remove and reinsert your sdcard.
4. Reboot out of CWM - Optional
If you still end up in a boot-loop just run these commands from adb to reset some security checks and get out of the CWM boot-loop. Check out this thread for an explanation of how this works:
http://forum.xda-developers.com/showthread.php?t=1444630
Follow these simple steps to reboot:
1. Go to "mounts and storage" in CWM menu
2. Select "mount /bootdata"
3. Execute the following code (thanks Bauwks!):
Code:
dd if=/dev/zero of=/bootdata/BootCnt bs=1 count=4
dd if=/dev/zero of=/bootdata/BCB bs=1 count=1088
reboot
You can also just go to "reboot system now" if the last line of code does not work.
Welcome back! Now get to work on some roms!

I can upload an SDImage that you can use. It would be made the same way Nook Color SDcards are made (google around), but this is a much bigger file and it will take me a while to upload.
What issues are you having?

A little harsh but yea... EJECT the sdcard from the computer after you're done partitioning, then INSERT that sdcard into the Nook Tablet's SDcard slot.
It doesn't get any simpler than that

can you post some screenshots or a video or two showing how cwm works on the NT?

Not every user here is at the same level of knowledge. XDA developers is all about sharing and learning, not bashing newbies If you cant respond in a friendly manner, then dont!
Please try to help fellow users, not give them a bashing!
We should all be working together here people!
I have deleted some posts to keep this thread clean!
@OP if you want me to delete more, let me Know
Peace!

Thanks for the steps man. Will give a shot in a minute.

Since this is the way to do CWM for this device, +1 for sticky imo

Write Image?
Can't we just write the image to an SD Card using Winimage?

---

Worked great. Backing up my image now as we speak!
If anyone has any questions doing this from Ubuntu don't hesitate to ask.

Would love to know the exact commands used from an ubuntu terminal and what programs i can use (not familier with ubuntu but i have problems using windows do to drivers being installed prior to root)

As a newbie, what advantages/benefits do I have from installing CWM (ClockWork Mod)?

pffff many things like backup your entire nook (system, data, recovery,cache...) and restore when needed (used when you test other ROMs, or you messed something up), you can wipe/format partitions, flash .zip files (used for patches, fixes, tweaks, etc... you name it) you can fix permissions, wipe battery states, use adb, mount/unmount partitions including sdcard (if you forgot to put the file you were going to flash for example lol) format your sdcard and create ext(used for "apps to sd") and swap partitions.

would be awesome, if somebody who has already done the steps,could post some pictures on how to do this under windows

I used EASEUS Partition Master to create a 50MB FAT32 primary partition on a 512MB SDCARD. Booted into CWM and am making system back now. This is great!!!

You have asked in a previous post, please do not repost. Someone will do this for you if they choose.

Easy and well done. Thanks to all involved in this effort.

Hey, in Ubuntu open terminal, put
sudo apt-get install gparted
Once you've done that plug your SD card into your reader, under system> administration (I'm running 10.10) select gparted.
Select the sdcard in gparted, format it in fat, create a partition in fat32 at 50mb.

For the partitioning, I used minitool partition wizard, easy to use and free. Google it or find it on my site http://www.makingitdigital.net/android/index.html
Cool, now I have not used adb shell or any of that stuff yet, so off to studying before step 2.
