Bricked after ODIN flash

Started out with 5.0.1 rooted. Flashed TWRP and CM 12.1 which went great. Wanted to go back to stock Android so I downloaded 5.1.1 from Sammobile, put my phone into Download Mode (without wiping it) and just flashed it with ODIN. It failed, and now I can't go into recovery, neither start it "firmware upgrade encountered an issue. please select recovery mode in kies and try again". Read somewhere that I could flash a pit file, but I will probably brick it for good if I try that. Does anyone know what I could do?
