I have a rooted Nook Color, and I have been trying to install Thum Keyboard for 3 days now. I also bought Root Explorer to copy files, to the Sym/app and it is there and I still do not show as an option when I try to change to thumb keyboard. It is in my applications, and on my sd card, I also installed both of the NK TKB Installer 1, and 2, still not an option, please help, thanks
