Recently bought kindle fire hd, happy enough only to decide to try to root it and have superuser access; now it has no graphics and runs slow. Its not a good idea i know but can anyone help. I did it by using a small program from the internet root and bin4ry, the program brought up 2 options normal or other i choose normal then on my kindle it asked me did i want to restore or something on a black page it asked me to type in a password then retype it to which i just left blank and went ahead saying ok to it, it then reboot coming up with no background where the slider is and very slow, although it does have the superuser app but again no graphics ? Thnks.
