G505 - Wrong BIOS - need to downgrade

I have a G505-20240. A Lenovo tech updated my BIOS to 82CN27WW(V3.00).  The currently supported BIOS is 82C24WWV.  (a lower version).  I tried to install the correct BIOS, but the utility wouldn't let me as it is a "newer" version.

Any help in downgrading my BIOS (to the correct one) would be greatly appreciated.
