XFX RX5700 DD Ultra Bios Flashing Issues

TS Rookie
After reading through the Techspot article related to flashing the XFX RX5700 DD Ultra to a RX5700 XT, I attempted to do the same thing with my DD Ultra, but keep on running into a SubsystemID mismatch error when using the AMD Flash Utility. I've tried every version of the XFX 5700 XT Bios listed under the Techpowerup VGA Bios repository as well as the XFX Bios Files listed on the XFX site.

Has anyone been successful in flashing this card as indicated on the Techspot article?

Does the bios flash need to be forced using command line to bypass the Subsystem ID check?

Appreciate the help.
