Since the recent firmware update when using thermal now it just shows a blank screen in whatever colour palette is chosen, has anyone else had this problem? I have tried connecting the M300 and H20t to the laptop to downgrade or refresh hardware but receiving errors every time it tries to transmit the firmware to aircraft?? any help would be much appreciated, cheers
