[REQUEST] Lenovo IdeaPad S300 whitelist removal

Hello!
I wanted to ask if someone could remove whitelist from my bios backup?

Model: Lenovo S300(uses same bios as S400 one)
Bios version: 6DCN88WW(v8.02)
Backup from FTP_BACKUP-BIOS running on Windows 8: http://www10.zippyshare.com/v/62485293/file.html

I also need to know what to do if something goes wrong and my computer will brick after flashing modded backup? Any way to recover it without sending it to RMA?

Merry Christmas Everyone!
