I tried today using QuickCure3, which seemed flash successfully, showing a USB Mass Storage in Device manager, but no sign of a drive anywhere. Then after a minute or so the USB disconnected and the device shutdown.
Now, when I try and flash the firmware it resets as before then shows "software missing" on screen until its restarted.. then its back to freezing on the garmin screen.
I'm fairly sure its a hardware fault.
