Looks like that worked! A strange thing happened towards the end of the writing part, as the display on the pedal red "READY" and then "BAD", and I also got an error message on the updater, but then the pedal restarted and it now shows the current FW version reading 5.8.5.
Hard to diagnose just by that. What error message did you see in the Direct Updater?
If you can use your pedal normally and the connect to it without any problems, then it should be good.
