Before you do anything — Make a backup

Don't forget to back up your data. If you have synced the device with a Google account, then the contacts, calendar, Gmail & select other Google-related data will not be lost and will come back after the next sync. However, you should backup anything you want to keep that is not stored on the SD card:

It would also be a good idea to backup everything stored on the SD card in the rare case the SD card must be formatted to resolve any major problems.

Backup for Root Users is a free application that can assist with backing up your data.

Rooting the Barnes & Noble Nook Color

Prior to rooting the Barnes & Noble Nook Color, it is recommend you register it with the Barnes & Noble.

Warning: Installing ClockworkMod Recovery on the Barnes & Noble Nook Color will void the warranty.

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.
    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.

  2. Select Flash ClockworkMod Recovery.
  3. Click on Barnes & Noble Nook Color and then give ROM Manager root permission, if it prompts you.
