Hello all,
After updating the bios via msi center application on windows 11 the pc didnt show anything on the monitor. So I followed the instructions in the motherboard manual to flash the bios and didnt work. As you can see the flash button is not flashing and the coms led always on. Please help me I have a lot of work to do :( .
My motherboard is z590 unify
Thanks a lot in advance

The board can be quite picky about which USB sticks it accepts, so try several. FAT32 formatting is a must!
You can 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).

Updating BIOS with Flash BIOS Button
1. Please download the latest BIOS file that matches your motherboard model from the MSI® website.
2. Rename the BIOS file to MSI.ROM, and save it to the root of your USB flash drive.
3. Connect the power supply to CPU_PWR1 and ATX_PWR1. (No need to install CPU and memory.)
4. Plug the USB flash drive that contains the MSI.ROM file into the Flash BIOS Port on the rear I/O panel.
5. Press the Flash BIOS Button to flash BIOS, and the LED starts flashing.
6. The LED will be turned off when the process is completed.

Thanks a lot for the kind replay, in 5. you said LED starts flashing in my case after I did all the above the LED either ON or OFF after flashing for 5 seconds only.
I believe there is something is not normal?!
thanks

Yes, it either didn't like your USB stick or you did something wong (no FAT32 formatting, MSI.ROM not in the root folder, incorrect BIOS update for the board etc.).

First, i would try a bunch of different USB sticks if you can, each prepared the correct way.

Hehe, yeah. Sometimes the USB Flashback function likes the cheapest sticks the best, i don't know why.
