Copy GUPDATE.GCD to the folder ..\garmin on the Edge Touring* while device connected through USB - device will have got a drive-letter.
Disconnect device from PC (advice: using the safe procedure - system tray)
Turn on and it asked "do you really want to update to this old firmware" - pressed Tick!
Done!
This took a bit of trial and error - I get two drives loading when I plug mine in, so have a couple of plain "garmin" folders. Just added it to each one until it worked!
Ps - And to prevent update to version 4.00 again: Every time Garmin Express has synced the device to Garmin Connect there will be a file GUPDATE.GCD in the ..\garmin folder on the device. Just delete it every time before detaching the device from your computer.
I followed these steps:
Download EdgeTouring_290.gcd from http://gawisp.com/perry/edge/ to your PC
Rename EdgeTouring_290.gcd to GUPDATE.GCD
Copy GUPDATE.GCD to the folder ..\garmin on the Edge Touring* while device connected through USB - device will have got a drive-letter.
Disconnect device from PC (advice: using the safe procedure - system tray)
