Question help, PC with M.2 SSD wont boot to widnows or bios

[pao3007]

Hi, I was flashing Bios on my Asrock B450 hdv r4.0 (with ryzen 1200), it was Bios P1.0 so i flashed it to P1.50 and then to 3.10, but after 3.10 flash my PC wont boot to windows or BIOS dont show up... only without M.2 SSD (without drives) i can access BIOS.... and with ssd its black screen, nothing show up at all,

so i switched m2 ssds between this pc and my second PC and both of them are booting, so m2 ssd is not damaged and so m2 slot is not damaged too...

Why did you upgrade bios in first place?

See if you can downgrade bios. If it worked prior to last update, that is the way to go.

cant downgrade, tried all versions, ( i wanted to OC my ryzen 1200 with using offset mode like i did in my another PC, but i didnt find it or something similar to it, so i saw that my BIOS was first release and i thought that it could be added in some of the newer ones...

Ok, that sucks if you cannot downgrade bios. So only solution seems avoiding mobos that have this impediment - or you have to buy another similar mobo and choose to not upgrade the bios if everything works.

Is the bios chip itself easilly replacable ?

well as i said in my second post, my MOBA works fine with my other nvme ssd (Win10 boots up etc.) and my M2 SSD (that which doesnt work with that MOBA after BIOS update) is working in my second PC...
now i tried cleaning that ssd and try to fresh install of win10 bit still no luck only black screen, maybe if i wait maybe 1 hour it will start working xD

maybe some changes are needed in bios... well if nothing works up i will buy new m2 ssd and this one i will send back to shop as i can return it in 14days after package arrived

anybody? fresh windows 10 install didnt work, like I was runnig my second nvme m2 ssd (adata) in the "faulty" pc and easily booted to windows and cam access BIOS, then I turned off PC, un plugged power cable and replaced nvme m2 ssd with the originally used m2 ssd (WD green) with Win10 installed on it and again no windows boot not even starting screen with hints like DEL, f2 to access BIOS, only black screen,

I can't help much more, I suggest you contact Asrock and ask them what to do.

Did you see the warnings about the driver needs for that BIOS and the display recovery SOP if you have issues?
