If u mean this:
, then search on Youtube for Crossfire Superjump, if it's not what u meant, then u probably mean a hack which is patched.
The fly glitch is patched if that's what your wondering about.
The fly hack is not released and/or its patched.
Alternative way to do a "super" jump is basically jumping once straight and before you land hit jump again and you'll have a higher jump on the second bounce.
