cant flash mmu 3.0.4 firmware to MMU
I flashed the core one firmware to 6.5.3 and tried to flash the MMU to 3.0.4. If fails the update. I've tried every method to push the firmware that I could find and have had no luck.
Is there a preferred method anyone can recommend? Do I have to down flash the core one to make it work?

I did it by using PrusaSlicer on a computer connected via USB to the MMU3 directly.
