So I followed the instructions on how to create a custom firmware to use on the Apple TV. I even got as far as getting the Pwnage Tool to open iTunes to restore the device. The process comes to a stop during the restore when I get a message that says the firmware is not compatible with the Apple TV. What, if anything, am I doing wrong? I am running the latest version of iTunes and it did download the latest version of the firmware to create the custom firmware with. Thanks.
