Falcon Avatar prop for xbox 360

I recently got the legendary code for halo reach but when I entered the code I never got the falcon avatar prop. I’ve been looking up how to get it and everyone is talking about how to access it through the old halo waypoint. How do you access it through the new updated halo waypoint? Plus when I re-download halo waypoint and then re-download the legendary code, I exit out of everything then something pops up really fast then goes away before I can even see what it says.

nevermind I got it
