I found that my recent purchased Barnes and Noble color Nook had an update. I had the option to wait for it to roll out or manually install it. I tried the do it yourself method. I went to this web site http://www.barnesandnoble.com/u/Software-Updates-NOOK-Color/379003190/ to get the instructions. I followed the instructions but the device would not install. What I got to work is I went in to look at the contents of my Nook hard drive and found the .zip file. I clicked on it once and it said that the file was not recognized. I finger tapped the file ikon a second time and it began to load. I am not certain this method was designed by the software engineers. I would NOT attempt this procedure until their method fails to work for you. Do try the Barnes & Noble steps first and see if they work for you. All I can tell you is it worked for me after waiting over half an hour for the Nook to do it by itself but utterly failed.
(Following black text, seen below, came directly from the Barnes and Noble web site. I added red text notes.)

8. Once the installation is completed, your NOOK will automatically restart and go to the unlock screen.
9. On the bottom left status bar a green “n” will appear. Tap on it for additional information; the software has been successfully updated. Yes, this did appear but when you finger press this little ikon, it puts up a small screen telling you have completed the update and then the little “n” will disappear.
NOOK Color must remain turned on while the update is being installed. Once the software is installed, your NOOK will automatically restart. To verify you have the latest update, tap Settings from the Quick Nav Bar, tap Device Info, then tap About Your NOOK, and check to see that your software version number matches the number at the top of this page.
NOTE: That zip file will seem to disappear off the Nook hard drive after the installation is complete. I think I did find it moved to “My Downloads” as a “6_Ticket.zip”. I pressed my finger down on the file and I was given only one choice of “Delete”. I chose to delete the file.
