Forerunner 165 screen stuck upside down (all reset options tried)

Hi all,

After I've charged my Forerunner 165 * with its usual charger and original cable * suddenly started showing everything upside down (the whole watch display is inverted).
I’ve tried everything I could find already:

  • Normal reboot / power off/on

  • Forced reboot (holding Light button)

  • Settings → System → Reset → Reset Default Settings

  • Both long-press reset combinations (Back + Light, Back + Up + Light)

  • Checked under Settings → Display (no Orientation / Screen Orientation option)

  • Connected to Garmin Express — no “Reinstall Firmware” / “Reinstall Latest Version” option is available

The screen is still inverted after all of the above.

Is there any other way to exit diagnostic / inverted display mode on the FR165?
Or does this mean it’s likely a hardware issue and needs replacement?

Thanks in advance for any pointers.
