I updated my device to the latest version through Garmin Express, I had to go into MTP mode to be detected by the program, I updated the firmware and disconnected the device, when it restarted first, appeared the Garmin logo and above it said "loader 26.18" and just after that it entered the USB MTP mode again, it is the only thing it does, I can not leave that screen, I have already restarted it about 80 times even pressing Lap/start, letting the battery be discharged or removing certain folders that indicated me in technical support and still not working, does anyone have any solution? For now my Edge 840 is an expensive paperback.
