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.

Copy all files and folder(s) from USB to some folder on your PC.
Then format the USB key with Rufus tool:

then copy and paste them back from the folder to the USB key,
then retry.

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.

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 ^^

Hi folks, I have a brand new problem. I have a B350 Tomahawk and an RTX 3050, and yesterday I made the mistake of upgrading the bios from 7A34v1M to 7A34v1Q6 (latest). To my dismay after a successful upgrade process the pc rebooted and it got stuck on 1 long, 2 short beep codes (gpu ez led). It would have been extremely unlikely that the 3050 died just there, but after some testing I got a GTX 750 and it booted, I tried everything, all the ports, disconnecting ssd/hdd/m2/usbs tried the mobo hdmi port (I read it somewhere that you get video there, maybe), and after talking with support today I tried changing the (windows) booting process from CSM to UEFI to no avail. With the 3050 it won't boot, with the 750 it does just fine. So, due diligence today I went to another PC to test the 3050 and it works too, so the gpu works, the mobo works, the PSU works.
To me it's an odd incompatibility between B350 tomahawk, RTX 3050 and this bios version 7A34v1Q6. I'm angry because I can't do a DOWNGRADE that could solve this grave issue AND on the web, refering to this BIOS version the changelog states:

Description:
- Update to AGESA ComboAm4v2PI 1.2.0.7.
- Improve the intermittent performance stuttering issue.
- Change the default setting of Secure Boot.
- Remove the support of AMD Bristol Ridge series APU.

Nowhere it says *WARNING* AFTER UPGRADING WITH THIS BIOS YOU CAN'T DOWNGRADE ANYMORE *WARNING*
It is clear now that I should have never updated, but I'm stuck now with an older gpu or a non-booting mobo. I pasted my experience on reddit and it happened to another customer, and I think many with this combination are bound to happen.

So, the question, I read that this flash tool is kinda miraculous, it may be what I need, but also says that it is NOT for 3XX mobos, like the one I have. So do you have any ideas, should I try to downgrade anyway?
Thanks in advance

You can have a try it, in a worse case can brick it, then you will need a SPI Programmer to restore it.
It's specified for those series that from some specified GSE BIOSes to non GSE flashing was causing the issue.

Sorry, I'm kinda noob in all this mess. How can I know if my BIOS is GSE?
