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. Make sure your computer has working adb.
  2. 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.
  3. 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. 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 or /sdcard as a mountable volume, go ahead and mount it. If you do not see one of these partitions, then instead mount the /data partition. Take note of which volume you mounted. Now, push the package(s) to your device (also, see tip below):
    - If you mounted /storage/sdcard0, then: adb push update.zip /storage/sdcard0/
    - If you mounted /sdcard or /data, then: adb push update.zip /sdcard/
    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.

Helpful Tip– SD card folders

CyanogenMod 10.1 and newer have multi-user support (introduced in Android 4.2). If your device has storage on the /data partition, then Android actually looks in /data/media/0/ for the first user's /sdcard/ storage. ClockworkMod recovery symlinks /sdcard/ to /data/media/ though. So, if you are pushing files to internal storage in recovery and want them to be visible in Android, you should push them to /sdcard/0/ or /data/media/0/. Here's the most frequent scenarios:

  1. If you're coming from a ROM with Android 4.1 or older to CyanogenMod 10 or older: adb push update.zip /sdcard/
  2. If you're coming from a ROM with Android 4.1 or older to CyanogenMod 10.1 or newer: adb shell "mkdir /sdcard/0/" followed by adb push update.zip /sdcard/0/
  3. If you're coming from a ROM with Android 4.2 or newer to CyanogenMod 10.1 or newer: adb push update.zip /sdcard/0/

Alternative ClockworkMod Recovery installation

ClockworkMod Recovery installation on Nook Color (encore) does not work through ROM Manager. Last version of Rom Manager and ClockworkMod does not support Nook. It could be checked by observing ROM manager page.

The working solution to the September, 2014 is to download image of ClockworkMod and write it to SD card as described in Setting up uNooter section. Setting up uNoter is not required. Note: this will destroy all information on SD card!!! CWM-6.0.1.2 SD image could be found on xda-developers on the post bottom download

After this step you should install CyanogenMod, as it will install "Universal" bootloader, which can boot to CM or CWM recovery. Stock bootloader ignore any keys combination. It boot from SD card if bootable one available, or from internal memory.

The latest version of ClockworkMod is 6.0.4.8 and is found in this post. link. This one is not a SD image! It could be downloaded to SD card (as a zip file) and installed throw available CWM recovery. Boot to the recovery by pressing nook n key. Than choose "install zip from sd card".

CyanogenMod should be installed through the same "install zip from sd card" method. Download suitable CyanogenMod package and [Google_Apps Google apps] package to the SD card. For CM 11 use 20140105 version, only this one have a "Google Play" service in my case. Alternatively, you can download minimalistic GApps

If your Nook shows SystemUI failed message, boot to the CWM recovery and make a date/factory reset wipe.
