Step 2: Since this utility is based on a restore jailbreak, which means you are required to have a custom built IPSW. Therefore select "Create IPSW" between the two option to continue the step.
Step 3: The Seas0nPass will now download Apple TV firmware and it will then utilize the file to create a custom jailbreak file.
Step 4: Now get your micr-USB cable to plug it into your computer and Apple Tv. However, don't plug into power cable, and then iTunes will be opening, close it right away.
Now put your Apple Tv into DFU Mode -- by holding the Menu and Play/Pause buttons together for about 7 seconds.
Step 5: When Seas0nPass has finished its jobs, now it's time for iTunes restoring the custom IPSW file in automatic manner. Then click yes. This process is fully automatic, just wait until it's entirely finished.
