ASRock AB350 Pro4 - Update BIOS to 4.70

I found the issue. The actual download for the BIOS Update was for the wrong motherboard. I had to click on the 'Chinese' Version when it gave the correct download.

Hey There,
I have had a similar problem the only difference being that I cant update my BIOS from 3.40 to 4.70.
I need to update to 4.70 to install my new Ryzen 5 2600.

I just updated it from 2.50 to 3.40 but it seems to be stuck on 3.40

Any suggestions?

Before a month, when I firstly installed the motherboard to my PC case and turned it ON for the first time, the BIOS was at version 3.20. I updated it (via Instant Flash from inside the BIOS menu) to 3.40, as the notes said, because this is a "bridge BIOS". Then after successful update - restart - load defaults - restart again, I updated to the latest 4.60. All works good since this time with the 4.60. Now, I want to update the BIOS to the latest, the 4.70. So, my question is: Shall I update it straight to 4.70 via Instant Flash? Or do I have to follow this procedure?: 1) downgrade BIOS from 4.60 to 3.40 (bridge BIOS) 2) then update the BIOS from 3.40 (bridge BIOS) to 4.70? The notes are not so clear thus I can't understand the 100% correct procedure to update.

Hi there,

I am wondering if you finally updated your BIOS directly from 4.60 to 4.70 version without going to any Bridge BIOS version in between.

I am in a kind of loop here as I have a new 2400G APU and the 3.60 Brigde BIOS version for my mobo (Fatal1ty AB350 Gaming-ITX/ac) do not support APUs. So we need to know for sure if going directly from 4.60 to 4.70 is a real option.

Any update in this kind of situations???

Note: The first BIOS update when the mobo was purchased was conduted by the vendor, I am not willing to take the entire system to the vendor anytime a new BIOS is released...

its very simple
if u have ANY 4.x already, then u can switch between ANY 4.x without bridge bios
bridge bios is needed only when u move from 3.x
same goes for older
going from 1.0 to lets says 3.50 is not possible
3.00 is needed (that is also bridge bios)

but feel free to use bridge bios, its just waste of time
that warning seems to be there to prevent bios brick
