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

I think you must not use the US 3.00 but must use the original one. Have you sved the orginal GUPDATE.GDC that was on the device? if so you can open that in RGN tool and save it to a RGN file and use that to flash.

That is what helped me to unbrick it.
But still no luck for me getting to Thai version
