Hi Guys,
I got a zumo 660 that had System Software Missing message.
I used Kunixs cure 3 to get it in Mass Storage mode and deleted all the files that could cause the problem, disconnected the device from the computer to flash the original firmware.
Then start the problem...
Insted of flash the firmware it is behaving like a pen drive. I can not get the firmware running, because it connects to the computer ...
