so I went through the process as described and it seems to have worked, I managed to create the new firmware and then I booted it tethered, or so I am thinking.
Problem is: As a next step I tried to access the aTV via SSH in order to install XMBCC and I get a "connection refused" as an error message, hinting to me that I did not successfully boot?
This is what the debug log shows me:

The device itself works after the boot fine, I can play netflix and access my iTunes, but obviously I wouldn't jailbreak it if that is all I wanted to do with it. Anybody got a tip?
