Once your custom IPSW file has been created, Seas0nPass will ask you to connect the Apple TV to your computer via a micro-USB cable and use the remote to put it into DFU mode by holding MENU and PLAY/PAUSE for 7 seconds. The power cable should be unplugged during this process. Tip: Connect the usb cable and press the buttons down at the exact same time.
Once your Apple TV has been detected in DFU mode, Seas0nPass will upload some files, ask you if its okay to automatically restore firmware, and then beginning restoring to the new firmware.
That's it! Your Apple TV is jailbroken!
