Hello Laurence

The usb I had was a 16gb kingston. I had windows 10 setup files in it. I just copied the bios folder and used m-flash from my previous bios version to enter into bios flash mode. Then I just browsed to the actual bios file and proceeded further. The flashing went just fine, but after it completed it never booted again and only the cpu led is lit constantly. The cpu is whirling at full speed...
Did you wipe the drive and specifically select format with fat 32 before you moved over the bios files?

No.. I didn't do that.. could it be the reason my system doesn't show post?
Could there be a possibility that the bios updated my board for a higher version of ryzen cpu and now it doesn't support my 2700x..?

Your CPU is definitely supported, your best bet now is to contact MSI support. Just tell them you followed procedure but it didn't work.

Oops! I downloaded the BIOS file from mobo's compatibility list. Maybe that explains why the text files are different. Sorry for the "fake news!"

Like Laurence said, better leave it at MSI support. They should know what to do. I'll keep my mouth shut for the time being. ^^

It's all right. We all make mistakes. That's the beauty of being human.. I am really thankful to you for trying to help me sort this out☺

So I think your initial suspicion about cpu incompatibility is probably correct. There are lots of posts for other motherboards with owners having issues after upgrading their BIOS that supports the new CPUs but they themselves did not upgrade the CPU. The disappointing thing, as you mentioned, is that there is no disclaimer on the BIOS file or website that says - if you don't have the newer CPU, there is no reason to upgrade the BIOS. If you didn't browse the forums - you'd think - why shouldn't one update to the latest BIOS, right?

Any way, there is mention of a special utility you could use to downgrade your BIOS (link here) back to the one that best supported the Zen+/2000 series CPUs, but I'd post a question to make sure it will work with your board (though I don't know how it would affect any warranty support if you go that route).

For your particular motherboard and CPU - I think you want 7A38vM4 (link here) and not beyond.
That's the same description for the BIOS on my x470 Board and haven't had any issues.

Hope that helps.

Thank you so much..
Clears some things for me.. Like I don't need to update my bios unless I am going for a cpu upgrade. I was just doing it because my m2 drive ceased to show up in bios and windows setup.. I thought maybe updating the bios would fix the m2 issue.. but landed me into another deeper problem.
All I wish is that you are sure about the proces you mention. Seems about right to me but I am not sure. Do you think my board would read the usb drive at this stage..? The utility you mentioned.., would it work without an OS..? I am really not an expert in this stuff.. hope there was some step by step tutorial or something to help me follow the right steps...
Thank you for the reply.

OP,
You said that your m.2 boot drive isn't/wasn't listed in bios? Could it be that your OS was installed via legacy/UEFI and not straight UEFI? I ask because my BIOS mode is listed as legacy and I recall trying to format my OS drive for a fresh copy of win10 a few months ago. Win Setup said it couldn't format the drive because it was in legacy (or some such). Now I'm scared to update my bios and be in the same boat.

As a matter of principle the latest BIOS should be used. A given board will have compatibility with a stated list of processors, that will not change.

new AGESA updates add processor support

Do you have the non-MAX or MAX version?
The bios file nonmax is about 8mb
The bios file max is about 14mb
Did you lose support for older Zen+ cpu when bios was updated? hard to say for sure.
cpu lists dont show bios version numbers required

If all else fails there is something called boot block recovery method.
It used to work with floppy but has been updated for a fat32 usb drive.
The USB would have to be DOS bootable (freedos) and the old style flasher exe is used
with autoexec.bat file. Usually the boot block stays intact during a flash.

The OP needs to contact MSI support as soon as possible. They need a new board and they might get one if they don't delay.

Yup, tried to flash my mpg x570-Plus this morning. Nearly lost my sh#t when it failed to enter m-flash and just gave me a black screen. Had to reboot twice to get back to OS. I've seen a few posts of people with MSI boards having the same 'black screen when clicking m-flash' issue.

Normally I would agree with that statement, but if you search some of the older posts in these forums - you will see the opposite conclusion.
There was a definite change in the BIOS file sizes from Zen/Zen+ to Zen2 that caused many board manufacturers to increase EEPROMs from 16MB to 32MB (MSI did it with their "MAX" line).

The op reported having a non MAX board and a Zen+ CPU, so in this case - not upgrading BIOS to the latest version would be a recommended course of action.

Perhaps rephrase that to non Beta version of the Bios.

I have samsung evo 970 250gb. It had windows 10 installed on it. Was working fine untill this blue screen came with error message "winlogon.exe" could not be accessible because it is not readable or corrupted, lr something like that. My system was working fine before.. it is this error that made me look my drive in bios and windows 10 setup. In bios the m2 slot said not available. In windows 10 setup, my m2 drive wasn't listed as a normal formatable drive. All this lead me to think maybe upgrading my bios to the latest version would fix this m2 issue. But it made more trouble for me. Now I can't even start my system, neither see any post.. i am sure the bios I flashed was successful..

The file I currently have in my usb drive is about 16mb's. It is max version as per size. The problem is now my system doesn't even read that usb.. I tried unolugging cpu from Mother board and plugging in the usb in hope it might read... But in vain...
