ASRock AB350 Pro4 - Update BIOS to 4.70

Hi. I have the ASRock AB350 Pro4 motherboard paired with an AMD Ryzen 5 1600 CPU and G.Skill Flare X 16GB (2x8GB) DDR4-2400MHz RAM.

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.

Are you sure? Because ASRock says "* Before updating this BIOS, please update BIOS to P3.40 firstly.", even in the 4.70 version..!!

Have you done this before?!

ASRock techs visits here are rare. This is a user forum.  If you need official reassurance then you must deal with ASRock directly.
Yes I have updated  both X370 itx and AB350 ITX  from vers 3.0 through to 4.50 within this last month.
Both of these MBs required that I installed the bridge BIOS before attempting to install later updates, once the bridge BIOS was installed I then had no further need to install it to install updated versions as I wished.
You only need to install the bridge version once.

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...
