Create Bootable SDCard with Custom ROM for Nook Tablet (8GB or 16GB)
Update 26/Jan/13 – XDA user Succulent has produced a CM10 (JB) version of the bootable SDCard for the Nook Tablet. It apparently works well and some of our users have tried it with good results. I have not experimented with it but I provide the links here if it is what YOU want to do.

The rest of this article is out-dated.
UPDATE 9/29/12: I no longer recommend this option. For an introduction to rooting and descriptions of other options, see our article… Intro to Rooting & Modding Nook Tablet.
This option still works as well as it ever did but there are now other better options (See our article here: Root for Nook Tablet 1.4.3). Some of the problems with this (no root) option are: 1) No upgrade path for this old alpha ROM 2) No practical way to do backups 3) Loss of all options and data if/when the SDCard fails.
- Micro SDCard. It should be at least 4GB but 8GB or 16GB will enable you to keep more local data available (the card will store both the operating system & all user data). Sandisk (brand) SDCards seem to work best as boot devices in the Nook. The card should be either class 4 or class 6 (larger numbers equal faster cards. Class 2 is too slow and class 10 seems not to work well.)
- USB to MicroSD Adapter. To attach the SDCard to your computer.
- Download the Win32 Disk Imager software here
- Download the CM7a (SDCard version) ROM from this thread on XDA. Direct download of the Team-B-CM7SD-Alpha_final.img.zip (MD5 1e1932c49dda7345a5575de2612af30a) or here.
- Create a folder for the Disk Imager software (does not matter where) & extract the contents of the zip file into it. Optionally, Right-click and drag the Win32DiskImager.exe icon to your desktop. In the menu, select “Create a shortcut here.”
- Extract the *.img file from the ROM file that you downloaded & copy or move it to the folder you created above. Note that the original (zip) file is only 115MB but the extracted image is almost 4GB so be sure you have sufficient space on the drive.
- Insert the MicroSD into the adapter and put it into one of the USB ports on your computer. Windows should recognize it and open a window to display its contents. Make a note of the Drive ID that windows assigned (e.g. “G:/”) If there is any data on the card that you wish to keep, you need to copy it elsewhere because the following process will overwrite any data on the MicroSD Card.
- Execute the Win32DiskImager.exe file. It will open a program window.
- Select the “Image File.” Click on the folder icon next to the field and locate the extracted *.img file.
- Select the “Device.” Click on the dropdown and choose the Drive ID that you noted when inserting the card into Windows.
- Click “Write” & “OK” to begin the process.
- Wait. According to the “Class” (speed) of the SDCard, it will take approximately 20 minutes to complete.
- When the process finishes click “Close”, & SAFELY REMOVE the SDCard (standard Windows process).
Procedure (How to use it)
- The SDCard is ready to use as soon as you safely remove it from your computer.
- Power off your Nook Tablet (this will NOT work in a Nook COLOR!)
- Place the new SDCard in the slot on the Nook
- Power on the Nook (The initial boot will ALWAYS take a long time – 3-5 minutes – just be patient. Later boots will be MUCH faster!)
- Complete the Android Setup & connect to your WiFi
- Use the device as is, add apps, change the wallpaper, save your bookmarks, and change or modify almost anything on the tablet.
- Dual Boot. When you power on the Nook (from an “OFF” state), it will boot from your new SDCard & come up in CM7. If you “REBOOT” from CM7, the Nook will power off and then come back up in the STOCK configuration.
- This is now YOUR PERSONAL device and whatever you do will ONLY change the contents of the SDCard – not the Nook its self. Whatever personalization you do will be retained for the next boot – even if you insert the card in a different Nook.
- For security, you may wish to keep the SDCard in a secure location until you wish to use it next. (It will retain any personal info that you tell Android to save or remember.)
