AppleInsider discoverd a growing thread at the Apple Support Communities website where users report issues after updating their Apple TVs (2nd and 3rd generation) to the latest Apple TV 5.1 software. It looks like many Apple TVs are getting bricked after running the update:
Apple TV hacker and developer nitoTV has recently shared some thoughts on the Apple TV 2 5.0 (iOS 5.1) and Apple TV 3 jailbreak. According to him, without an A5 bootrom exploit being found, an Apple TV 3 jailbreak “will be an uphill battle.” That’s mainly because the “attack surface” on Apple TV is much smaller:
Downgrading to older version of Apple TV 2 firmware just got easier, thanks to a new version of Seas0nPass. Recently released by FireCore, Seas0nPass 0.8.2 uses previously saved firmware signatures (SHSH blobs) to jailbreak and restore an Apple TV version that Apple may no longer be signing.
aTV Flash 1.3 automatically backups Apple TV firmware signatures (SHSH) to the cloud. Backing up firmware signatures allows older Apple TV firmware versions to be reinstalled in the future. According to FireCore, this feature will integrate seamlessly with the upcoming version of Seas0nPass, allowing for one-click restores to the firmware of your choosing.
Apple TV 2 software has been updated to version 4.2 (iOS 4.3), which brings new capabilities to those tiny black boxes that are still not jailbroken or are ready to lose the jailbreak. MLB.TV and NBA Game Time are now available as streaming content options, AirPlay has been updated to support video from iOS apps and websites and the support for Dolby Digital 5.1 on Netflix has been added (the full list of new features is below).
As you already know, if you don’t want to lose your jailbreak (and all the apps/plugins/add-ons you’ve already installed) you can’t update. But if you have SHSH blobs saved you can update to 4.2, check out the new features and then decide whether you stay with these ones or you prefer to go back to your old jailbreakable 4.1.1 (iOS 4.2.1) to enjoy some other great features it offers (XBMC, Hulu, aTV Flash and many more).
