I have been lurking for awhile, and have a rooted 1.1 NC. I am having trouble with a few Children's books I bought, so I wanted to make sure it's not me rooting my NC. I have reverted back to stock NC 1.1 and still have the problem ( "Internal error: Reader does not support available file type"). I am thinking of "updating" to 1.2 to see if that helps, but just want to make sure I can go back to my rooted 1.1 via my backup on my bootable CWR SD card before I do. Thanks for appeasing a newbie!
