A few minutes ago the FireCore team announced the availability of a new version of Seas0nPass for Mac that brings untethered jailbreak for the Apple TV 4.1.1 – also known as iOS 4.2.1 for all other devices.
All credit for the untethered jailbreak process goes to the Chronic Dev Team. Seas0nPass for Windows is also being finalized with the untether and will be available soon.
The latest Beta3 version of aTV Flash (black) is compatible with Seas0nPass, GreenPois0n and Pwnage Tool jailbreaks.
A previous version of the app with tethered boot option was released in January. There aren’t many tweaks and apps available for the Apple TV yet, so feel free to try this if you’re really willing to experiment with the little black box.
