Apple TV 2G jailbreak using PwnageTool 4.1.2 is almost similar to any iPhone jailbreak with PwnageBundle. The only major difference is that you have to use iOS 4.1 specific for Apple TV instead of iPhone or iPod iOS.
We have already shared the complete tutorial to jailbreak any idevice using pwnagetool in detail here, but we are going to share the procedure again skipping those steps which are not needed in Apple TV 2G jailbreak.
