The PC fails to start following the BIOS upgrade.
Today I attempted to update my MSI MEG B550 Tomahawk BIOS using M-Flash. The update completed successfully at 100%. After restarting, the CPU light stayed red and no progress was made. When I tried flashing again, the process started blinking, power turned on, and the button blinked five times before nothing happened. I've tested multiple USB sticks (six in total), removed everything from the motherboard, and connected only specific ones formatted with Rufus using fat32. I've used different BIOS versions (3.0, 2.0) from various brands like Kingston, SanDisk, A-Data, XPG, and Patriot. All components are installed, but I can't proceed to return warranty service since I'm not in the USA.
