Lenovo E470 BIOS Pass

[Elkomaster]

Regards to all folks.
Let me say I locked laptop today. It had a Supervisor password but I didn't know that and I tried to upgrade the bios.
After the reboot I entered the wrong password three times and now it is locked.
Please, if anyone has a desire to help, I would be grateful.

I read everything from the post above but I still have no idea.

I tried to restore the original dump, but I keep getting a black screen. How is it possible?
