Initialised usb , (. was looking for Mount manager ) didnt see it , been a while but am sure it used to ask to mount after initialisation .I don't think we need a post mortem, just initalise the usb and run the command line again, takes 10 minutes.
Anyway , ran the script agin , "succesfully flashed box will reboot ib 3secs " , box didn't reboot am still looking at a freeview channel in openatv.
