[Request/Help]TOSHIBA Satellite L505-13Z

[simone.pri]

Hi i'm trying to unlock my BIOS for see if is possible to have more settings in it.
My laptop is:
TOSHIBA Satellite L505-13Z
And the bios can be downloaded here:
BIOS Download
or directly here:

  bios.rar (Size: 1.87 MB / Downloads: 16)

Some other info:
BIOS type: Phoenix EFI
BIOS name: Phoenix SecureCore Tiano
BIOS version: 2.1
motherboad: NSWAA

I've tried to download: "Andy P's Phoenix/Insyde SLIC tool", but as I have no experience with BIOS mods, I don't want to do something wrong and brick my laptop.
Can anyone gently help me to archive this mod if is possible?
Best regards,
Simone
