The Firecore team has released the updated version of Seas0npass which includes support for untethered jailbreak on iOS 4.2.1 (iOS 4.1.1) Apple TV 2nd generation. Currently, Seas0nPass only supports 2nd-gen Apple TV 2 and is Mac OS specific (Mac: OSX 10.6 or later). 


Step 6: Once in DFU mode, iTunes will open automatically to start the restore process. You will have untethered jailbroken device after the restore process completes. Now remove micro-USB cable and connect the HDMI cable and start installing other apps. Once you are done with the jailbreak, you can install the following apps on your jailbroken 2nd-gen Apple TV.
