The most current version of the NOOK GlowLight 3 software is Version 5.5.
From time to time Barnes & Noble will release software updates for your NOOK. Your NOOK will automatically install these updates.
NOTE: 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 update is available, your NOOK will download it and install it sometime over the course of a couple of weeks after Barnes & Noble releases the update, and while your registered NOOK device is idle and connected to a Wi-Fi hotspot. There is nothing else that you need to do to receive these automatic software updates. Software installations take only a few minutes. Updating your software doesn’t affect the contents of your Library or the titles listed in your Keep Reading list. 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.
You check for the availability of a new release by tapping the Check for System Update button on the Software settings screen, which is described below.
Finding the Version Number of Your NOOK Software
To find which software version your NOOK is running, do this:
1. Tap Settings in the NOOK Navigation menu to open the main Settings screen.
2. Scroll to the bottom of the screen and tap Software.
Your NOOK opens the Software settings screen, which lists the version number of the software release your NOOK is running.
Checking for the Availability of a New Software Update
NOTE: You must be connected to a Wi-Fi network to check for a new software update and to install that update
on your NOOK.
1. Open the Software settings screen, as described above.
2. Tap the Check for System Update button.
Your NOOK checks for the availability of a new software update. If one is available, it begins downloading the update. Your NOOK automatically installs the update after your device next goes to sleep.
