I tried restoring my iPad with a ipsw for iOS 5, but the error message "The iPad could not be restored. This device is not eligible for the requested build." popped up. I was told to go to terminal, and enter a code: sudo nano /private/etc/hosts which i did. then i entered my password. now i was supposed to change a program in terminal, but that program doesnt show up. why isnt it showing up and how can i get it to show up so i can fix my problem?
