I tried to update the BIOS from my MSI B450 GAMING PRO CARBON AC to the newest one, I downloaded it from the MSI website, I put it in an USB stick and plugged it to the computer, entered m-flash to the bios and everything correct. What's my surprise? When I go to the "new" BIOS I have this.

Which I believe is a very very older version because the one that I had before was much more modern and had a lot of options more than this.
I tried to flash an older version of the BIOS and nothing happens, I mean, it flashes but it keeps the same BIOS, I tried to update it from the MSI Live Update 6 and nothing happens too. I would want to return to the BIOS version of december 2018 or something similar(when I bought the mobo).
Can anyone help me?
Thanks

As of 7B85v17, the BIOS format changes. It's specifically stated on the BIOS page.

Change BIOS UI to click BIOS(GSE-Lite) mode
https://www.msi.com/Motherboard/support/B450-GAMING-PRO-CARBON-AC
https://www.msi.com/page/mb-beta-bios

The ROM size was insufficient to account for code for the 3000 series CPUs, so they had to scale back some BIOS features to ensure it was compatible with newer CPUs.

You're not likely to be able to downgrade after the change - and any microcode updates etc, which you'd want for improved stability, would re-implement anyway.
 
Look around a bit just to make sure the "more settings" aren't still there and look different.

New BIOS flash tend to be larger than the one before. This is why we sometimes see BIOS revisions continue on for (some) manufacturer boards while (others) seemingly within a similar line don't have the update. The chip this is held on is only so big. The graphical interface may have been simplified to allow the new update.
It is not uncommon for a motherboard not to allow reverse BIOS (downgrades) without an intervening program. Often if you read the notes for the revision it will state that you can't go back.

When I tried to flash the older BIOS from the newest one it said something that for better perfomance they didn't allow to do that, but I guess that in case I really wanted the older BIOS I could reset all the BIOS with the Flashback+ or something likr that. Thank you. And I would say thst the "more options" aren't there or they are worse because I used to have graphs to change the fan speed and now they are simplified in numbers withouth graph

Ok, thanks, I will try to downgrade anyway but if all the things are in the new BIOS, I will search for them(eventough I prefer the UI of the older

Functionality should all be there. It should be a matter of the UI, and dropping some support for entry level Athlon's and the like, to ensure there was room for the code for 3000 series CPUs.
