Unable to update BIOS with B550 A-PRO
I have attempted to update my BIOS multiple times with different BIOS version. I have three 8GB 2.0 USB sticks, formatted to FAT32 and partitioned to MBR. My current BIOS build is from 2020. I have downloaded five separate version ranging from 2021-2025 on the official MSI website and each time I M-flash, the USB is detected, but the files are no found.
I have also tried to the flash bios button, naming each MSI.ROM separately on different tries. When I do, the BIOS led will blink red a few times, the fans starts, and immediately the led remains red seeming to be either stuck or failed to continue.
I'm not sure what else to do and am stuck. All of this is trying to get TPM 2.0 enabled.
Let me know if there is anything else I can provide to help further troubleshoot. Thank you.
