I had to gravity bleed mine, open the valve all the way, or even take it out. Hold down the pedal(forever) and just keep putting fluid in untill the bubbles stop coming out and you get a steady stream of fluid, then replace the valve and tighten it until it's closed. It takes forever, but it works, this is the only way I could get the piston inside my caliper to even move.
