You love NBA and MLB but you haven’t yet updated your Apple TV 2 to iOS 4.3.1 because you love XBMC, Hulu, Couch Surfer, Plex and Remote HD even more? The waiting is over and you can now have it all as iPhone Dev-Team has released untethered iOS 4.3.1 jailbreak for all iDevices (except iPad 2). Just update your tiny black box to 4.3.1 (Apple TV 4.2.1) and then re-jailbreak it with the freshly released PwnageTool 4.3. Note that PwnageTool is Mac only, Windows users will have to wait until redsn0w is updated to support atv2.
untethered jailbreak
Firecore has updated Seas0nPass to support a tethered jailbreak of the new Apple TV 4.2 (iOS 4.3) software. Seas0nPass allows you to jailbreak your atv2 with the latest 4.2 software by creating custom Apple TV IPSW files and restoring them in iTunes (similar to the existing Pwnage Tool app). It also includes a simple ‘tethered boot’ option.
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.
Greenpois0n RC6 has finally been released by the fantastic Chronic Dev Team. This magical piece of software jailbreaks your Apple TV 2 on iOS 4.2.1 (Apple TV 4.1.1) in a flash. And this is untethered jailbreak, meaning you don’t have to connect your atv2 to your mac/pc every time you need to reboot it.
Here is the step-by-step tutorial on how to jailbreak your Apple TV 2 using greenpois0n rc6.
