This just in, FireCore has updated the Apple TV jailbreak utility SeasonPass with the version 0.8.2 which includes a stitching feature that lets you downgrade your Apple TV’s firmware to an older version which Apple has stopped signing.
Today we are happy to release a new version of Seas0nPass that simplifies the installation of older firmware versions. This process called ‘stitching’ allows Seas0nPass to utilize previously saved firmware signatures to jailbreak and restore an AppleTV version that Apple may no longer be signing.
Firmware signatures are required to install a particular firmware version onto iOS devices like the AppleTV. When installing the latest version, these signatures will be created in real-time during the iTunes restore process.
