Bios Mods -The Best BIOS Update and Modification Source

I am getting the same output as jaylee75 while using this guide....

Edit: ok this is embarrassing, apparently there are SPACES in "PHLASH16 /S /X /FORCE" before slashes, whats why it did not worked for the first time. Did not see them at all.

I´m using the original "BIOS Update" guide from the above menu. I already have my mod bios, but when I try to flash it I get the error:

Phoenix Phlash16 Error
Platform Signature Not found in the Interface
PRESS ANY KEY TO REBOOT

The /S /X /FORCE will skip this error? Or will brick my BIOS? tks

Sorry for newbie question.
Can I use Rufus to create free-dos boot pendrive instead MS-DOS?

I also have different image ".usf".
I was flashing yesterday bios in my lenove m57 by bios from lenovo side, but just by creating iso on CD and flashing automatically, using same program Phlash16 and loaded bios on screen was same in .usf.
