A new software called Seas0nPass has been released by FireCore, developers of media center software for Apple TV 2G. Just like another jailbreak program, PwnageTool, Seas0nPass lets you create the custom IPSW firmware to jailbreak your Apple TV 2G on iOS 4.2.1 with the Seas0nPass jailbreak.

Still running 4.1 on your Apple TV 2G? Learn how to jailbreak untethered on iOS 4.1 using PwnageTool 4.1 here.

Currently Seas0nPass is a tethered jailbreak, meaning which you are required to connect your ATV 2G to a computer every time you reboot. Also the jailbreak tool works only for Apple TV 2G, and not with any other iOS device, including iPhone, iPod Touch, or iPad.

Mac OS X version of Seas0nPass is available as a free download, while the Windows version is expected soon.

NOTE: Currently the jailbreak for the 4.1.1 (iOS 4.2.1) software is 'tethered'. A tethered jailbreak requires the AppleTV to be connected to a computer for a brief moment during startup.

Seas0nPass makes this as easy as possible, but please do not proceed unless you are comfortable with this process.

What You Will Need:

1. Download and install the latest version of iTunes (check for updates through Software Update located in Apple menu).
2. Download Seas0nPass [Mac only - Windows version coming soon]
3. A micro USB cable will be required to complete the jailbreak.
4. 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. Please proceed to the 'tethered boot' section below.

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 below, 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 time to do this, so you don't need to haveSuperman speed).
