I have downloaded and installed the intermediary file then followed by https://www.dropbox.com/s/n5nk0fxkhzosvp2/XR500-V2.3.2.134-dumaos33-rc14.img?dl=0
This never worked and got the incorrect firmware notification. So I proceeded to download https://www.dropbox.com/s/mb7hztmwpxnpz2i/XR500-V2.3.2.134-dumaos33-rc10.img?dl=0 and then hopefully upgrade from there.
But no! I'm getting hit with this.
