So I turned my softrooted Nook on this evening and left the room for five minutes. When I came back it was in the process of rebooting, having downloaded and installed the 1.5 update. Now when I turn my Nook on, a screen appears where I can choose home or launcher. Home takes me to the newly installed 1.5 OS. Launcher takes me to the softrooted 1.4. everything still works, I essentially have a dual bootable Nook now. What do I do?
