Mac Mini (mid 2010) interrupted firmware update. I cant recover

Mi Mac Mini (mid 2010) only blinks rapidly, no slowly, the apple logo and progress bar show up, the bar blinks twice and the mac mini shuts off. I can eject the CDs turning on and pressing the eject key, so i think some BIOS is there... Im trying MacMiniEFIupdate CD 1.5

What am I doing wrong??
