This guide will walk you through the process of taking the Nook Color from stock to having a custom recovery image and the ability to flash the latest version of CyanogenMod.

Important Notes

The Barnes & Noble Nook Color (aka encore) is a touchscreen tablet manufactured by Barnes & Noble. Official CyanogenMod support for the Barnes & Noble Nook Color was added in CyanogenMod 7.


Setting up uNooter

In order to properly flash an uNooter image to a SD card, you will need to use an USB card adapter or have an internal SD card slot on the computer. Writing the uNooter image to the SD card will wipe it, backup anything of value and/or importance elsewhere.

  1. Download the uNooter image:
    • uNooter: download
      md5: 4e1e7be9939aaef43d3a1d04cb17b2cd
  2. Unzip the uNooter zipfile.
  3. Write the uNooter image to the SD card:

Windows

  1. Due to Windows not having the ability to write images to drives, you will need win32DiskImager to accomplish this. Latest version should be fine.
  2. Insert the SD card you are going to use to write the uNooter image to.
  3. Open win32DiskImager.
  4. Select the downloaded & extracted uNooter image with the folder button.
  5. Select the drive letter for the SD card.
  6. Write the uNooter image.

Linux

  1. Insert the SD card you are going to use to write the uNooter image to.
  2. On the computer, open up terminal and navigate the directory where the extracted uNooter image is located.
  3. Once in the same directory as the uNooter image, type the following commands:
    umount /dev/<sdcard>
    NOTE: <sdcard> is the device file associated with the SD card, e.g., sdc or mmcblk0, and NOT the mount point, e.g., sdc1 or mmcblk0p1.
    dd if=uNooter.img of=/dev/<sdcard> bs=1M

Mac OS X

  1. Insert the SD card you are going to use to write the uNooter image to.
  2. On the computer, open up terminal and navigate the directory where the extracted uNooter image is located.
  3. Once in the same directory as the uNooter image, type the following commands:
    diskutil list
    NOTE: This will help you identify the SD card. Make sure it is the SD card & not one of the hard drives of the computer.
    diskutil unmountDisk /dev/<sdcard>
    NOTE: <sdcard> is the device file associated with the SD card, e.g. disk2.
    dd if=uNooter.img of=/dev/<sdcard> bs=1m
  1. The uNooter image is now setup on the SD card. Continue to the next section.

Gaining Root Access

  1. Power off the Barnes & Noble Nook Color. Also if the device is connected to a computer, disconnect it.
  2. Insert the newly setup uNooter SD card into the Barnes & Noble Nook Color.
  3. Connect the Barnes & Noble Nook Color to the computer. This will trigger the Barnes & Noble Nook Color to power on (the screen will remain off) and allow uNooter to root the device. This screen is black for up to ten minutes.
  4. The computer will see a new USB device.
    • Windows: The computer may complain about missing drivers. Simply cancel through them at this time.
    • Linux: The Barnes & Noble Nook Color will show up the computer as a RNDIS ethernet device. You may ignore this.
    • Mac OS X: The Barnes & Noble Nook Color will show up as an additional Ethernet device. Just cancel when you see the dialog box pop up.
  5. Once this occurs, disconnect the Barnes & Noble Nook Color from the computer. The Barnes & Noble Nook Color may restart itself. If it restarts normal, continue to the next step. If it does not, power it off, remove the SD card & power it back on normal.
  6. At this point the Barnes & Noble Nook Color is rooted. Continue to the next section.

Install a Custom Recovery Image

If the Nook Color already has the ClockworkMod Recovery installed, you may skip this section.

  1. In the Extras menu on the Barnes & Noble Nook Color, launch ROM Manager.
  2. Select Flash ClockworkMod Recovery.
  3. Click on Barnes & Noble Nook Color and then give ROM Manager root permission, if it prompts you.
  4. If it hangs after that and freezes up, just allow the app to Force Close. Then open it back up and repeat steps 2-4.
  5. Once the flash was successful, you should see a dialog box that says "Successfully flashed ClockworkMod recovery!".
  6. Press OK.
  7. The ClockworkMod Recovery should now be installed on the Barnes & Noble Nook Color.

Installing CyanogenMod from recovery

  1. Download the CyanogenMod package for your device that you'd like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  2. Boot to recovery mode, and connect the phone to your computer through USB.
  1. In ClockworkMod Recovery, use the physical volume buttons to move up and down. On most devices, the power button is used to confirm a menu selection, but for some devices a physical home key acts as a selector. Some devices have touch enabled ClockworkMod Recovery, in which case you may be able to swipe to, or touch, menu selections.
  2. Optional (Recommended): Select backup and restore to create a backup of your current ROM.
  3. Select wipe data/factory reset.
  4. You have two options for transferring and installing the installation packages. Both cases require adb to be working in recovery. The sideload method is more universal across devices, whereas the push and install method is more commonly used:
    • Sideload method: select install zip > install zip from sideload. Follow the on-screen notices to install the package. The installer does not necessarily display an "Install complete." message. You can tell the install is complete if there were no fatal error messages and you have regained control over the menu.
    • Push and install method: Open a command prompt (or Terminal on Mac and Linux) and navigate to the directory holding the package(s) you would like to install. On the device, navigate to the mounts and storage menu. If you see /storage/sdcard0 as a mountable volume, go ahead and mount it. If you do not see this directory, then instead mount the /data directory. Take note of which volume you mounted. Now, push the package(s) to your device:
    - If you mounted /storage/sdcard0, then: adb push update.zip /storage/sdcard0/
    - If you mounted /data, then: adb push update.zip /sdcard/0/
    where update.zip should be replaced with the package filename. Go back to the main menu and select install zip. Choose to install from the same directory where you pushed the package(s). If you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it.
  5. Once installation has finished, return to the main menu and select reboot system now. The device will now boot into CyanogenMod.
