Epson Epson Stylus CX5400

firmware for metal type printhead

I want to fix my old printer Epson CX5400. I bought a new printhead (old one is borken) for it and now im trying to replace HEAD ID with new one, but there is a problem. Printer's firmware "exclusively for driving silicon type head" so i need to replace firmware but i can't find it anywhere. Can someone help me please?
