I recently updated my BIOS version (yesterday). Today, a BSOD appeared, the first in months. I am almost 100% that the reason for it is the BIOS update, as it didn't work out and had another error just after the update. I was wondering whether there is someway in which I can downgrade my BIOS version? I would really appreciate if you can help me. My laptop is Lenovo Z510. Thank you.
