Just got the Nook color and it was updated to the new version. I want to root it but don't know where to go from here. Also, how can I view comics on the nook? I used calibre to convert the cbr to pdf. I think I did it correctly. For some reason, my nook doesn't connect to my computer. Giving me driver issues. I suspect a faulty cable. Therefore, I put the pdf's on a microsd card but it gives me an error when I try to open it. What am I doing wrong?
