Strange you're getting that message, if 41 was protected from copying you'd get this of course:
Parsing "rrgn,41,1:/41.bin"
Error

41 isn't protected in 'normal' 2xx5 and they definitely copy to '1', not '2' as the 2013 devices do.

All 3 commands rrgn/ergn/xrgn are there in fw so i can't understand why you get "Error: invalid command 'rrgn' ".

On another note Angelo, do you happen to still have V2.30 fw to help this guy out?: [Only registered and activated users can see links. ].
