BSOD after BIOS update.

[venom0706]

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.

Was the bios update fully completed, or were there any interruptions?

It was fully completed, but after it, an error started to occur and I couldn't boot into Windows. I had to switch the boot mode from UEFI to Legacy in order to be able to boot into Windows. Now everything is fine, I even re-installed the OS, but apparently the update stayed, as I tried to install an older BIOS update and it says that a newer version is already installed. I am afraid of the BSOD appearing again.
