[Request] Thinkpad t450s unlocked BIOS

Hi guys,
The windows of my Thinkpad T450s is corrupted and I don't remember the Supervisor Password which it set earlier. I assume that the password might be removed if I flash the chip with the new clean BIOS ".bin" file. May I ask if someone has a clean T450s BIOS file that can share with?

Thank you so much for your help.
