Just tried to JB my first ever AppleTV, to run Plex. Failed at the first hurdle! Followed all the instructions for the latest model at AwkwardTV, used PwnageTool, made an IPSW, did the DFU thing, opened iTunes, tried to restore it using the new IPSW and got an error 21. This happened numerous times. Then I figured it was coz I was using the last beta of iTunes before 10.1, so I updated to 10.1, and got the latest OSX update too, and tried again, same errors. So I tried to just restore back to the original firmware and after it downloaded the file from Apple it failed while preparing the AppleTV for restore, error code 1611, and that's all I get now. Is it dead? How the heck have I managed this!?
