Red triangle in recovery

[JohnnApolia Harper]

While flashing fk23 leaked rom my battery died. Now my phone powers on, shows the Samsung logo then the screen goes black and then nothing. When I go into recovery I get a red triangle. When I try to flash anything I get this message, E: signature verification failed. I can get into odin mode but no pc will recognize my phone. reinstalled drivers, switched usb cords no luck. Can anyone help?
