Is it possible to root the Nook Color 8gb running 1.4.2? I've heard it's not entirely possible. I installed the "Go Launcher Ex" Using an SD card image, but am still unable to install "unknown files." Checking that box in settings doesn't work as it only unchecks again as soon as you leave. Also, the original Nook OS continues to run in the background eating half the RAM. Is this possible to root yet?
