Execute the update command via an elevated Command Prompt or by running the utility installation assistant. The software will detect the custom BMP file, compress it into the new BIOS image, and prompt you to reboot to flash the firmware.
The open-source community has developed several powerful tools for Lenovo users seeking to push the boundaries of customization.
Modifying system firmware carries inherent risks. Ensure the machine is connected to a reliable power source. Never interrupt a BIOS flash procedure, as doing so can permanently brick the motherboard. Troubleshooting Common Implementation Issues

Run the flash command with the logo parameter. Depending on the model generation, the command will look like one of the following: WINFLASH.EXE /L LOGO.BMP wflash2.exe /logo:LOGO.BMP
