Barnes & Noble is providing a free software update for NOOK GlowLight Plus™ devices that provides important new features and enhancements. The software update will be automatically downloaded to devices that are registered and connected to Wi-Fi®, beginning October 21st, 2015. There's no need for you to take any action to receive the update. However, if you'd prefer to update your device immediately, you can manually check from your NOOK for the update over Wi-Fi®.

You can check manually for the software update over Wi-Fi®. Tap the Settings icon on the Quick Nav bar from the Home screen, page to the second Settings screen, then tap on Software. While connected to Wi-Fi®, tap on “Check For System Update”. Your NOOK will check for a new software update and start the download immediately. Your NOOK will proceed to install the update when it goes to sleep.

Your NOOK must remain turned on while the update is being installed. Once the software is installed, your NOOK will automatically restart. When the software has been successfully updated, a dialog should open to tell you more about the update.
