How To Jailbreak Apple TV 2G Untethered On iOS 4.3 Build 8F455 Using Seas0nPass [Mac OS X/Windows]

Earlier today we told you that the FireCore development team worked closely with Comex to develop an untethered Jailbreak for the iOS 4.3 (8F455) firmware.

As this is a significant update for Apple TV 2G owners, we have decided to write a how to guide for jailbreaking your Apple TV 2G running the iOS 4.3 firmware untethered on the Mac OS X operating system. In this how to guide you will learn how to Jailbreak your Apple TV 2G untethered running the iOS 4.3 (8F455) firmware.

Note: The jailbreak process is the same for Windows users.

Step 1) – The first thing you are going to need to do is download Seas0nPass for Mac OS X from our downloads section.

Step 2) – Once Seas0nPass has downloaded you may need to extract Seas0nPass if this has not been done automatically (Safari only).

Step 3) – Once Seas0nPass is extracted you will need to double click the Seas0nPass app.

Note: if this is your first time launching Seas0nPass you will need to enable UI scripting.

Step 4) – When Seas0nPass has launched you will notice two options presented to you – Create IPSW and Boot Tethered. The option you will need to click is Create IPSW.

Step 5) – After clicking the Create IPSW button Seas0nPass will begin downloading the iOS 4.3 (8F455) firmware for your Apple TV 2G. After Seas0nPass downloads the firmware file it will begin creating your jailbroken IPSW.

Step 6) – Once SeasonPass has created the custom IPSW you will be prompt to connect your Apple TV 2G into your computer and to put your Apple TV 2G into DFU mode (follow the on-board instructions). Once your Apple TV 2G is in DFU mode Seas0nPass will automatically open iTunes and start the restore process.

Congratulations! You have just jailbroken your Apple TV 2G untethered running the iOS 4.3 (8F455) firmware. Let us know if you have any questions or concerns in the comments section below…

  2. Hi

    My apple TV 2G IOS 4.3.3 is unjailbreak with season Pass, i follow each steps until to restore iTunes last version normally , but my apple TV is always unjailbreak , why i can’t jailbreak 

  3. Same problem as previous comment. Go through all process but the Apple TV2 remains unjailbroken…???? Help

  4. I have the same problem like the comments before.

  5. Actually, I discovered that the new jailbreak does not show Menu option ‘Seas0npass’ on the apple tv, once the jailbreaking process has completed. My Apple TV was jailbroken after all.  Test it out by running ATVFlash Black. If it loads then it’s jailbroken.

    Hope this helps.
