I noticed you updated your BIOS on the MSI Z490 Gaming Edge Wifi...
Did you touch base with MSI customer service prior to doing so to ensure if it is safe to update to this bios?
I inquired about the safetly of bios v.19 when I noticed it was pulled from the list of bios updates and was instructed, " please do not flash the bios by M-Flash or LiveUpdate, if you want to flash the bios in the future, we can provide you a tool to update the bios".
Instead I was given a google drive link to a copy of AFUWININTEL and told to use this for future bios updates; I was also provided with instructions detailing how to use AFUWIN.

This appears to be a work around for the moment.
I did ask if they plan to utilized M-Flash or Control Center in the future but have not heard back yet.
no shot I'm going to reach out to MSI customer service every time I want to update my BIOS with THEIR publicly posted, non-beta version updates, just to "double check this one won't brick my whole motherboard this time".

I've RMA'd the board since I've only had it for 6 or so months, but I'll be upgrading to a non-MSI board after I've had this one for a year or so

With the Z490 ACE, you have no problem. Just use the Flash BIOS Button to flash an older BIOS version, or flash the current BIOS version until it works again.
My old Asus board from 2012 had the exact same system USB and flash button for bios recovery. I wrongly thought all MB from there had this feature, and that's note the case with the Gaming Edge Wifi I own. Lesson learned, even if all went fine for me so far. I really can't get stuck with my computer at this period of my life...

Format the USB stick as FAT32 non-bootable with the help of https://rufus.ie/en/ (i would use this tool, it has more of chance of working than letting Windows format it).


You don't have to take out any hardware like your CPU for this, it's just a demonstration in the video.
Thank you, it worked for me without rufus (i formatted my usb with windows), thank god there is people like you helping. Anyway, I always do a Mflash, this time i tried their .exe update. I will never try it again. Have a nice day

The BIOS that we have for the latest for the Z490 A Pro is 7C75v2C Is the number you have quoted a typo?

New bios listed for Z490 Unify.
For the Z490 ACE, UNIFY and GODLIKE, this whole problem might as well not exist. They have a Flash BIOS Button and can always recover from a failed flashing process. So whatever BIOS they release, even if the update fails on the first try, on those boards you can just force-flash it again until it works.

As for the "new" update, this is pretty much the same update they temporarily pulled before. According to two users who tried to flash this "new" update on their lesser Z490 models, they got the problem again, so it's not fixed by that update alone.

The most recent sign of MSI working on this issue was this post with the AFUWINx64 method, but surely MSI can't expect lots of people to use command line tools again like 15, 20 years ago.
I'm hoping for genuinely new updates soon that will fix this potential problem once and for all.

But has anyone tried the AFUWINx64 method?
Some expert on the subject can put a tutorial and if this method does not give an error, we use it while they correct the error and we avoid dead motherboard.

Adding myself to the list. Had to RMA. They returned the same physical motherboard to me so they must have a way to unbrick it.

Date of failed flashing: September 7, 2021
Affected board model: MPG Z490M Gaming Edge Wifi
CPU: 10700k
Flashing method used: m-flash
Attempted update to BIOS version: from 2.7 to 2.9
Result: Stuck at EZ Debug LED "CPU" after update.

Date of failed flashing: 08-Oct-2021
Affected board model: MAG Z490 TOMAHAWK
CPU: i7-10700
Flashing method used: Using M-Flash from BIOS (BIOS file was stored on NVMe OS Drive)
Attempted update to BIOS version: Version 7C80v19 to 7C80v1A.
Result: Stuck at EZ Debug LED "CPU" after update
Memory: Corsair Vengeance LPX 32GB (4x8GB) 3200MHz CL16
Overclocked: No

So I've sent the board for RMA and is back and working after 2 weeks.
A very interesting finding is that my Intel NIC now has this MAC Address 88-88-88-88-87-88
I've tried a bootable linux installer and it shows the same MAC so is not spoofed by the OS.

That BIOS does not even show on the support page we have, the latest is 7C75vAA ,and before that 7C75vA8 so it may be one that was taken down .

OK so I am unbricked now using a CH341A USB programmer. It was a bit difficult having never used one before but 2 hours of messing around learning how it works and $15 and I am back in business.

Z490 Tomahawk. I reverted to 7C80v18. I havent tried updating to 7C80v1A again.
