Firecore has released an updated version of Seas0nPass that includes an untethered jailbreak for the Apple TV 2 on iOS 4.2.1 (Apple TV 4.1.1). It’s Mac only for now (OSX 10.6 or later) but according to Firecore, Windows version is also being finalized with the untether and will be available soon. If you’ve already jailbroken with greenpois0n (RC 6 or RC 6.1) you do not need to re-jailbreak – both Seas0nPass and greenpois0n contain the same jailbreak components.
XBMC has finally been released for the new Apple TV. Here you have all the instructions you need to get it working on your device.
NOTE: the following HOW-TO requires you to have Jailbroken ATV2 version 4.1 or 4.2.1.
Here is how to jailbreak your ATV2:
How to jailbreak Apple TV 2 on iOS 4.2.1 with Seas0nPass
How-To: Jailbreak Apple TV 2G on iOS 4.2.1 with PwnageTool
Here are the tips:
1. Some users have reported issues with ‘wifi sync’ enabled. Disabling this (if currently in use) seems to resolve a number of issues related to restoring in iTunes.
Seas0nPass is a new jailbreak tool designed by FireCore specifically and exclusively for the AppleTV 2 (no other iOS devices support). This magic piece of software allows you to jailbreak your atv2 with the latest 4.1.1 (iOS 4.2.1) software by creating custom AppleTV IPSW files and restoring them in iTunes (similar to the existing Pwnage Tool app). It also includes a simple ‘tethered boot’ option which aids in using newer AppleTV firmwares when an ‘un-tethered’ jailbreak is not yet available.
Seas0nPass is available for free, and is open source (the source code is available on Github). It’s Mac only (OSX 10.6 or later) for now but the Windows version should be released soon.
Here are the instructions on how to use Seas0nPass to jailbreak the Apple TV 2:
iOS 4.2.1 brought only some minor bug fixes related to resolution and download problems, so if you updated to 4.1.1 you are still able to jailbreak your Apple TV 2G with PwnageTool. All you’ll have to do is to use new PwnageTool bundle to jailbreak iOS 4.2.1 instead of iOS 4.2 PwageTool bundle. Note that this jailbreak is also tethered, which means you have to connect your Apple TV 2G with PC and use Redsn0w or PwnageBundle to boot it.

This is just awesome: iOS hacker quiqueck made it to install Plex on the jailbroken Apple TV 2. Based on the open-source XBMC, Plex now works as a client for your ATV and lets you stream nearly any kind of video from your server (read your Mac). Plex for ATV2 is just a “proof of concept” so it is still buggy, tricky to install and limited to video playback (no music files, no images, no App-Management) but anyway, this is looking really good for the future of Apple TV2 applications (after the Weather app, this is the second iOS app that works on the new Apple TV).
