It's clearly not the latest firmware as the update says that the  
version will be MP11.005C.B01 after a successful update.

Are you pressing and holding the power button on the Mac and not the  
keyboard, are you seeing the flashing light and then the progress bar?

Have you tried following the second part of the Note (included below)  
included with the instructions?

Note:
This update requires a Macintosh formatted disk or partition. If you  
are starting up using a RAID (Redundant Array of Independent Disks)  
subsystem, you must attach a Macintosh formatted storage device to  
apply this update.

Some USB and FireWire devices may prevent firmware updates from  
installing correctly. If you are having trouble installing an update  
try disconnecting non-essential devices and use only an Apple branded  
keyboard, mouse and monitor.
