Thinkpad X1 Yoga Gen 3 ,How to know if the BIOS is corrupted

[bermo96]

Flash the original bios back and see if it boots ok. Check that the serial number is correct, it isn`t recognised at lenovo support.

Yes the serial number was hard to read on the label.
But I manage to bypass the supervisor password with this patched BIOS.

HI Team.
I have a ThinkPad X1 Yoga 3rd gen that has a SPV password.
I tried unlocking it with the autopatcher, but after flashing the patched file I only got 3 blonks on the power button.
I flashed the original file, buth same effect.
I would appreciate any advice and help.
