From time to time Barnes & Noble may release software updates for your NOOK. Your NOOK will automatically install these updates.
Updating software does not delete any of your books, magazines, or newspapers, nor does it delete any of the files you have transferred onto your NOOK from your personal computer. The software update simply installs new NOOK software to give you the latest features available from Barnes & Noble. Your NOOK remains registered to your Barnes & Noble account, and all your reading material remains accessible.
Installing a Software Update over a Wireless Network
When a new software release is available, your NOOK will download it and install it when you next connect to a wireless network. A small NOOK symbol will appear in the far left corner of the Status Bar when a new software release is available. Tap on the NOOK symbol to learn details about the release.
Once the software installation is complete, you can continue reading or shopping or doing whatever else you were doing before the new software was installed.
Determining the Version Number of Your Current NOOK Software
To discover which software release your NOOK is running:
Tap the Quick Nav button to open the Quick Nav Bar.
Tap on the Settings icon.
Tap on Device Info.
Tap on About Your NOOK. You’ll see a screen listing the version number of the NOOK software installed on your NOOK.
