I bought a bootable sd card from amazon (CyanongenMod 7.0.3). Very pleased with it. But I'm selling my nook color along with the sd card I bought to a friend. I can't find anywhere how I can do a factory reset from within settings. I do a factory reset but it just boots back normal with my account still there and all. I did a factory reset on the nook itself but I just cant figure out how to do it within android. Please help. Thanks.
