Bios Mods -The Best BIOS Update and Modification Source

Hey there, I would like an unlock (advanced tab) for my BIOS. Is it possible?
Also, please tell me if you give me a link on how to put this bios on my existing one, should I use the lenovo utility?
Thanks in advance!

Thanks!
Can you show me a tutorial on how to flash this?
Thanks in advance

Create boot usb-stick, copy the files there
reboot and run flah.bat

Thanks for the instructions.
When I tried, I got Error 280: Failed to disable BIOS write protection.
Any ideas

As agreed, here are the new attached files (I successfully downgraded my BIOS)

Hi.
Thank for the efforts. However I got Error 28: Protected Range Registers are currently set by BIOS, preventing flash
access.
Please contact the target system BIOS vendor for an option to disable Protected
Range Registers.
I tried to run prr2.exe but it was not successful. Any ideas?
