Erase & Deregister Device
The Erase & Deregister feature erases your Barnes & Noble account information from your NOOK and resets the
NOOK to its default factory settings. Deregistration unlinks your NOOK from your Barnes & Noble account.
NOTE: Erasing and deregistering your NOOK does not delete any of the books, magazines, and newspapers
from your Barnes & Noble account. Your reading material, while no longer available on your NOOK, is
still available for downloading and for reading with NOOK applications, such as NOOK for iPhone and
NOOK for Android. In addition, you can re-register your NOOK by following the same steps you used
when you first set up your NOOK. Once you have registered, your complete Library is once again avail-
able on your NOOK.
NOTE: Erasing and deregistering does delete any files you have transferred to your NOOK from your personal
computer. Be sure to back up these files before erasing and deregistering, if you want to have access to
them after deregistering your NOOK.
NOTE: Be very cautious using this feature unless specifically instructed by Barnes & Noble’s Customer Support.
NOTE: You must be connected to a Wi-Fi network to deregister your NOOK.
