So my Nook Color had been rooted since the beginning. However, I had decided to sell it to my friend, but he wanted the stock firmware (for what reason, I don't know). So I set out to unroot my Nook, but I believe I only half-unrooted it. The reason is because it booted up into the stock firmware, however, I saw remnants of rooted apps that I had installed. Can someone provide a complete tutorial on how to unroot my Nook. I seemed to have followed the instructions wrong and now the instructions that I was using aren't applicable. I just don't want anything to happen to the Nook Color and have my friend be mad at me. Any help is appreciated! Thanks!
