1. Turn the device off
2. Touch left top side of the screen and keep touching it.
3. Push the power button and the garmin logo will show.
4. insert the USB cable
5. Drag your original RGN file to updater.exe

now you should be able to select USB in updater.exe and be able to start flashing.
you can now release the left top side of the screen.. this worked for me
