I’d be happy to help you fix this. (It’s still just to cool to see my skin working in a R8!!)
The ProductID message is pointing in a direction which might be not to hard to solve.
During all the ssh commands, have you ever had a wired connection?
Somehow it seems the script can’t generate it’s first params if there never was a wired connection.
Please try to connect to internet via cable and then select the skin again.
If this does not work, could you send me a print screen of your settings menu (I don’t need IP addresses, you could erase them if you want / or send private message).
