Then I guess you can find the latest BIOS for it here:
Ok a bit of a long shot but. Can i buy the bios chip and then solder it onto my motherboard instead of the oem one?

If you mean to cross-flash at own risk:
You can use SPI Programmer with SOIC Test clip depends what BIOS chip is in there.
Or if you find from somewhere intel fpt tool for proper platform to raw flash the bios.

I've got an Aegis RS 10TD-059US with a BIOS ver: E7C75IZ1.2A1 and I'm trying to flash to E7C75IZ1.2A3.

Mflash gives the "For providing better BIOS functionality and quality, the system will not allow to restore BIOS with older version after flashing this target BIOS" error and will not update. I tried this UEFI Shell Flash tool and it does not recognize the E7C75IZ1.2A3 file.

Any ideas?

Just bought a used B550 Gaming Plus and it came with a B550A-PRO BIOS *facepalm*
I'm trying to use your tool to fix it (v1.17), but I can't get it to work.
My USB Stick (formated as FAT32):

And I get a message saying "There are too many BIOS Files on the storage", which there isn't, there's only one.

As boot selection on Rufus, should I select "Non bootable", "FreeDOS" or "Disk or ISO image (and select something as image)?
And partition scheme should be MBR, GPT or Super Floppy Disk?
Thanks for your response.

What model is shown in BIOS Setup?
Now after I flashed with your tool it's the MPG logo, but is was showing Pro Series logo before.
The model shown in CPU-Z is MS-7C56, which is the same for Gaming Plus as I looked for. I flashed 7C56v1A BIOS version, which is the latest on MSI website.
And the motherboard is in fact a B550 Gaming Plus:

Got it, then you may need to reinstall OS to fix the detection in there ^^
