I dont know if they have another usb tool , i guess they have live update -usb tool and M-flash .
Are you sure you tried MSI HQ USB BIOS Flashing Tool ,not m-flash

I guess m-flash and MSI HQ USB BIOS Flashing Tool are difeerent things because msi recommends DONT use m-flash while they are proud MSI HQ USB BIOS Flashing Tool had 100% success .But i have not got first hand experience with them and MSI HQ USB BIOS Flashing Tool is hidden to non-members (did not have a chance to loook and dont know how it works )
Edit : Found a guide for MSI HQ USB BIOS Flashing Tool
