Forum:Mantis XP leg glitch and Title update 5

Has anyone been able to get the Mantis Foreleg XP glitch to work by deleting Title Update 5 on their 360? I've tried it multiple times with no luck. I've tried it with no DLC, with DLC, with no Saves, with the base game, ect. Still not working for me. I've even tried to find a way to transfer Title Update 4 from my PC to 360 to see if that works, but haven't had any luck in doing that. Any help and feedback is appreciated.
