A copy of the original firmware is stored on the hidden EFI Partition. This partition is created when you reinstall Mac OS X.
To mount this partition:
$ sudo mkdir /efi
This will create the mount point for the EFI system partition
$ sudo mount -t msdos /dev/disk0s1 /efi
You could find it under /efi/EFI/APPLE/EXTENSIONS/Firmware.scap

But now we need to find a way for "EFI Firmware Update.app" to load the original Firmware.
