cant downgrade my bios on MSI Motherboard

Go to solution Solved by Beerzerker,

Yes, an external programmer is most likely required because the manufacturer has purposely blocked flashing back to an older file according to the onscreen message.

This practice of blocking a flashback to an older version is done by all makers for various reasons, alot of it just being a load of BS but really to insulate themselves from a world of RMA's.

This is an example (Note it's only an example) to illustrate the kind of tool refered to for reprogramming the board's BIOS chip but note there are different BIOS chip types too.
You'd need to be sure of what the BIOS chip type is on your board to have the correct connector/tool to do the flash with - Not all BIOS chips are alike even if they happen to look about the same.

Just note I'm NOT saying for you to go and do this, there is a real risk of bricking the board anytime a flash is done and if you're not familiar with "How" a flash routine works it's best left as is - At least the board still works and that's the important thing.

Just remember any future BIOS upgrades will push what you've got along even further, locking you out of any versions older than what you had before.
If the board is working without issue there is no need to flash it.

hello, i have an B350 TOMAHAWK motherboard,
I updated my bios 2 weeks ago to the latest Version an i wanted to downgrade it to another version yesterday.

 but somehow it doesn't work as you can see in the picture and I wanted to ask if it works somehow or not

I tried to put versions from 2019, 2018 on it but all didn't work.

Why you want to downgrade the BIOS? It has some kind of issues?

Anyway, as I can see, you are trying to perform the flash in the BIOS it self, check if your motherboard has some software that does the same from inside Windows, perhaps it has some other options to force the flash of the older version.

Desolder bios chip, program on a bios programmer, and resolder is the most obvious way to force flash

 

Though you could try using an engineering version of afudos to force flash bios, maybe look up ways to force flash bios online

 

This thread may be of some help but i am not sure if intel me system tools can flash bios on an amd board, worth a shot ig

Some mobos have a BIOS setting to allow downgrade, can look for that. But if not you're indeed stuck there other than external programming.
