   According to me Yes, you can downgrade the BIOS version using Instant Flash. 
Here i mention you can do this-
You can get the recommended BIOS version from the ASRock website.
Format a USB drive to FAT32 and copy the BIOS file to it.
You can restart your PC and press DEL to enter BIOS setup.
Go to the Tools tab, select Instant Flash, and choose the BIOS file from the USB.
Also you can follow the on screen instructions to complete the process.
Downgrading BIOS can be risky.

	As I said in my last post, ASRock includes that warning to discourage people from needlessly updating. There is no benefit to 4.90 over say 3.50 if you are using an older gen CPU. That said, there is also no issue with using it, especially if that is what your board shipped with. Bare in mind that for motherboard manufacturers the vast majority of returns are as a result of bad BIOS flashes. Discouraging pointless updates saves them money, time and customer dissatisfaction. I would complain about it but in the end, it saves a lot of people heartache and frustration so ultimately, its for the user's own good.

	No, you cannot downgrade BIOS, I'm afraid. Newer motherboards now has flashback capability, but not older ones

	That's I'm saying. In description of 4.90 version says "*ASRock do NOT recommend updating this BIOS if you are going to use Pinnacle, Raven or Summit Ridge CPU on your system." Ryzen 3 2200G is Raven Ridge. In 3.50 version don't says anythink about that. Can I instal 3.50 version with instant flash method? https://www.asrock.com/mb/AMD/B450m%20Pro4/?fbclid=IwAR3aOtL-Fi3d5emQiAHK6DWXwbJ2SMeyZU29UhNbMtqKWjH1o-8oG1OVRvM#BIOS

	The best thing would be to find out if those restarts and "black screens" are related to BIOS/CPU situation, and not a consequence of some other issues :)

	If your system is working, don't do it. The "not recommended for" comment is just ASRock trying to discourage people pointlessly flashing their BIOS.
