How do I update my nook?
Only registered devices get updates over the air. The update should occur automatically (wirelessly). Make sure you have wireless connectivity (Airplane mode should be OFF). Go to "My B&N Library" & press "Check for new B&N content". Your nook will proceed with the update.
You can also "side-load" the udpate via your computer. MANUALLY DOWNLOAD UPDATE HERE, Just put it in the root folder of your nook. Eject your drive(s) and it will do the update! If you have problems make sure the file name doesn't have a -2 or -1 added to it by your browser. It should be singed_bravo_update.dat!
