Stuck on eternal bios flash button blinking

Hello to everybody! I would appreciate this very much if someone could give an idea on how this situation may be dealt with. When I populated my new MPG X570S CARBON MAX WIFI with 5950X, Corsair memory module and RTX3060 the POST showed 00 with red CPU in the EZ Debug LED. Thinking the BIOS update to its latest version may shed some light, I relied on the flashback feature. I tried all the variety I could. A dozen of USB USB2.0-3.0 pendrives, all formatted FAT32, MBR, bios renamed to MSI.ROM, precisely as instructed in the manual and numerous youtube videos. The flashing start always goes smoothly. The flash button blinks slowly several seconds then the board turns on and it starts blinking faster but no reading indication from the pendrive. That's it. I tried waiting for minutes, hours to no avail. The button never turns off and the board never reboots. Is that a sign the mb or bios is dead or there is some chance the board can start if, say, put an earlier Ryzen? 3500x, for instance?

The Flash BIOS Button method can simply be very picky about the USB stick. In fact, the old and cheap USB sticks with small capacity seem to work the best for that method, read here or here. You need to find a USB stick / pen drive that the board likes. It needs to flash for about 5-7 minutes and then it will reboot. Anything drastically different (under a minute of flashing, or over 10 minutes of flashing) and the flashing didn't work. Then you need to find the one USB "pendrive" (we call them sticks here) that the board accepts.

Also, it would be good if you could list all your hardware in detail (what RAM, PSU, drives).

Thanks for the reply and for the links!
Yes, I noticed that it's picky indeed. :) Every new stick which fails to flash the BIOS gives a little hope that the next one should definitely be a lucky one. The question is how many of them I have to collect till the moment I can be called a weird stick collector? :) I am not kidding. Every colleague of mine instead of saying hello now meets me with, "No, no, man, you already asked, I don't have any old USB sticks left..." :) I also formatted them with Rufus allegedly the most successful way to prepare. I do consider perhaps an option to try to flash the BIOS with CH431A directly but cannot find location of JSPI1 connector which MSI usually embedded in their earlier mbs.
Sorry, I didn't list my hardware.

MB: MSI MPG X570S CARBON MAX WIFI
PSU: Thermaltake Toughpower GF1 850W
DDR4: CORSAIR Vengeance LPX 32GB 3600Mhz
SSD: SAMSUNG 970 EVO Plus

I also forgot to mention, that I tried flashing the mb completely bare with only PSU 24pin and CPU 8pin connected and fully populated. No visible difference though. All these parts I tested on other main board. They are fully functional
I wonder, maybe someone had some similar experience? Any help is very appreciated.

Your other hardware looks good.

You should have had a USB stick from MSI included with your board (it has some outdated drivers on it). Try with that one.

Yes, the stick was included in the box. What drivers can be useful before I manage to boot the main board? Besides... When I run out of sticks this one was the next candidate to be formatted and put MSI.ROM file on. :) I tried all BIOS versions from v10 till the last v13. Didn't work either...

If you have used USB drives under 32GB both 2.0 and 3.0 etc the Formatting is correct and you have tried several USB Drives already and all give same results and you have tried each several time I would say it is time to to RMA the board.

Try only the latest v141 beta, https://www.msi.com/Motherboard/MPG-X570S-CARBON-MAX-WIFI/support
This is the one you want. It fixes a bug of the v13. Don't be afraid of the "beta" tag.

The drivers on the MSI stick are useless, because they are outdated, you can get newer ones from the support website.
Thank you for the advice! This is exactly what I did today, when I spotted a new update is available. Unfortunately the problem remains. The rapid blinking of the Flash BIOS button had been for an hour after which I couldn't do anything but to turn the PSU off... Looks like to RMA the board is the only option I have left... Thank you, Citay, anyway.

You can abort after 10 minutes. All successful flashing i've heard about took around 5-7 minutes, not much more, not much less.
Maybe there's really a fault with the board, because the 5950X should work even with the factory BIOS.

It would be good if you could test with a different CPU. Let's say your CPU is faulty, then of course you would always get the CPU LED. And because you still haven't found that "magic" USB stick that the board can be flashed with, the flashing doesn't even work without a CPU in the socket. So it confuses which is the real issue: A faulty CPU or a faulty board?
Of course, when you RMA the board, you will get an answer to that. The problem is, what if the new board has the same problem - then you know it was the CPU, not the board...

You are right. I guess, it makes sense to make sure the problem is not in the CPU before RMA the board. If the process of flashing had gone well and I still had the POST 00 with CPU error, then the culprit would have been obvious. So far it is not clear. Thank you!

@solev15a602e1 i have had the exact same problem this morning.

I was re-installing MSI Dragon Center because lately i did not had anything related to my Mystic Light and such. (Running an MSI MPG B550 Gaming Plus, S. AM4 v2)
The installation did not change anything my Mystic Light and such were not there, so i hopped to update my bios as i was running 1.70 and the latest was 1.90.
It updates...
It reboots...
No screen, all black (it's already my second B550)...
Tried to dump CMOS, playing with the pins, nothing ... always the reboot for flashing and the red blinking forever.
it made me crazy...
it logged a ticket but this will be a pain and days of wait i fear.

I feel for your situation if you find a solution hit me up !

I confirm MSI Support is mainly delaying the warranty usage of the pieces we buy from them.
They can't read what we write them, they just reply something useless instead of triggering the warranty and exploring the brick reasons of their motherboards by their own software.

Sad but after discussions at some stores, MSI is not in good shape regarding returns, their product quality is downgrading. They don't even read their own community forums to spot real issues.

To conclude i'm trying to get my motherboard sent to them to justify the brick and replace, but in the meantime i bought another one from a competitor.

Just use the Bios Flashback function

Is why it is on the board to rescue them who use MSI Center to upgrade BIOS

Some directions for you



FOR BIOS FLASHBACK

Following Directions are for windows based OS

Right Click on the Downloaded Bios Zip File, select properties if you see the message this file is blocked by windows tick the box to unblock and click OK.

When in windows File Explorer make sure that you select the View tab and Tick the box Show Hidden Files and File Name Extensions.

Extract the BIOS file from the Downloaded ZIP file Open the folder it was extracted to.

Right click on the BIOS file, select copy and then paste it into a 32GB or smaller USB drive drive Formatted to FAT32.

When in Windows File Explorer make sure that you select the View Tab and Tick the box Show Hidden Files and File Name Extension.

Now rename the BIOS file to MSI.ROM

There should be no other files or folders on the USB drive, just the BIOS file you have renamed to MSI.ROM


FlashBack can be used on a fully assembled PC even if CPU is one of the new 5xxx series.

PC must be turned off for BIOS Flashback to be started do not turn on your PC the Bios Flashback will do it for you




Plug the USB Drive in to the USB port just below the Bios Button,

Do not touch any Jumpers on the Motherboard

Push the FlashBack button and then release it,

About 5 seconds later a led just above the USB port will start to flash, after 15 seconds of so the speed of the flashing light will double this is the writing to the BIOS period.

Once done writing to the it will stop flashing and PSU will turn off

For 16MB BIOS it will take about 4 to 5 minutes, and flashing stops.

For 32MB BIOS it will take 6 to 7 minutes, and flashing stops.

People have said that it may turn back on if so just turn off and unplug the PSU.

And Bios should be flashed.

Failed BIOS flashback is one of three way

One- it never stops flashing
Two- Solid LED no flash and stays on till you power of PC
Three- it flashes four of 5 times and then stops


Successful it will flash for about 15 to 20 seconds it will then it will start flash quicker for 4 to 6 minutes and then turn off.

Are you trolling ? Seriously ? Did you even read the thread "Moderator" ?

We have exactly the same issue, flashing does not work, and blocks in a constant state of red blinking. The Motherboard is bricked, i'll wait for the warranty to be triggered by your support just to prove it to you.

I'm sorry but you just prove my point regarding MSI... Shared on twitter to @msifrance

This post is not a manual to the problem I finally managed to solve, but rather a hint to those who stumbled upon the same problem - constant blinking of FLASH BIOS BUTTON, that happened on my new board. If you tried several USB2.0 sticks with no more than 32Gb capacity, and you had no signs of reading data from the stick, with the POST signaling nothing but 00 with the red CPU led indication, tried different CPUs, waiting for the finish of flashing that never came, then the best solution would be to RMA the board.
If you have no opportunity to do so, then with some additional devices and skill you can do direct flashing BIOS by programming the chip via CH341A programmer, but keep in mind that the process can easily ruin the board unless you understand exactly what you are doing.
Before flashing the latest BIOS image to my 1.8v smoc flash memory chip via programmer, the surprise for me was that the chip was already empty or completely cleared (probably by some accident). I don't know how it could happen but it did. If you still have no way to RMA the board, accept the risk of damaging it but desperate to fix it by your self, then this can come in handy that helped me in my case.


Thanks to everybody who participated in the thread!
