FireCore has released updated Seas0nPass v0.8.2 with firmware stitching which means the install process of old iOS firmware is more easy and simple now.
Official words:
“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.”
You can download Seas0nPass v0.8.2 from source, where you can also find detail tips about Seas0nPass jailbreak tool.
Firecore has released the updated version of Seas0nPass which includes support for an untethered jailbreak for the AppleTV 4.1.1 (iOS 4.2.1) software.
