Jailbreak Apple TV 2G 4.2.1 Using Seas0npass for Windows & Mac (Tethered) - {Guides - Download}

NOTE: Seas0nPass provides an 'un-tethered' jailbreak for the latest 4.2.1 (iOS 4.3) AppleTV software. This means the steps found under the "Using Seas0nPass for a tethered boot" section can be skipped.
Seas0nPass troubleshooting tips can be found HERE.

Pre-launch checklist

• Make sure you're running the latest version of iTunes.
• Download Seas0nPass: Mac [10.6 or later] | Windows [XP or later]
• A micro USB cable will be required to complete the jailbreak.
• Disconnect all iPods, iPhones, and iPads from the computer before running Seas0nPass.

Using Seas0nPass to jailbreak the AppleTV:
Step 1: Unzip the 'Seas0nPass.zip' file and launch Seas0nPass.

Step 2: If your AppleTV is not yet jailbroken, select 'Create IPSW'. (if already jailbroken, and you just need to do a 'tethered boot' scroll down).

Step 3: The latest AppleTV software will be downloaded and used to create a custom 'jailbroken' software file.

Step 4: When prompted, connect your AppleTV using a micro-USB cable (leave power disconnected), and hold both the 'MENU' and 'PLAY/PAUSE' buttons for 7 seven seconds.

Step 5: iTunes will open automatically and start the restore process.

Step 6: iTunes will confirm the restore when complete - your AppleTV is now jailbroken!
You will now see the Seas0nPass menu after connecting the AppleTV to your TV.

Using Seas0nPass for a 'tethered boot':
Some AppleTV software versions require a tethered boot. This means the AppleTV must be connected to a computer for a brief moment during startup.
Note: The AppleTV MUST be disconnected from the computer (for at least a brief moment) after restoring in iTunes for the tethered boot process below to work properly.
Step 1: Open Seas0nPass and select the 'Boot Tethered' option.

Step 2: When prompted, connect the AppleTV to your computer via USB. Wait for the rapid flashing light then connect the power. Once both are connected hold both the 'MENU' and 'PLAY/PAUSE' buttons for 7 seven seconds.

Step 3: Seas0n Pass will complete the tethered boot automatically. Once complete, remove the USB cable and connect the HDMI cable.

Note: Timing is key. Once the you receive the success message shown above, the USB cable should be removed and HDMI cable connected before the light on the front of the AppleTV stops flashing. (Don't worry there is ample to do this, so you don't need Superman speed).
Thanks.
