Well I’ve finally done the untethered jailbreak of my apple tv 2 and I’m really impressed with the results.
The jailbreak wasn’t too difficult (although I still use pwnage tool to get the apple TV 2 into DFU mode as it seems much easier). Once in DFU mode I plugged in the power cable then it’s just a case of running greenpois0n RC6 (mac version) and hitting the jailbreak button. Once it says complete, wait around 40 seconds before removing the usb cable and inserting the HDMI cable. You will have an extra tab on your apple tv called greenpois0n. Click this and click install cydia and it will download cydia from the repository using apt.
