Garmin Oregon 450t - Firmware Issue “SYSTEM SOFTWARE MISSING”

Post by olaiten » Sat Aug 10, 2019 3:52 pm

My Garmin Oregon 450t has either a wrongly firmware version installed or even missing or broken firmware.

Hitting the power button immediately show “SYSTEM SOFTWARE MISSING” and the Garmin logo below.

Forced USB Mode via USB cable and push/hold power button for several seconds does not work.

Forced Firmware Update/Downgrade via USB with Firmware Utility “Updater.exe GUPDATE.rgn” and push/hold power button for 30 or more seconds does not work.

How would have Garmin installed initially a firmware on a blank device?

Does anyone knows a solution? Many thanks!
