I really can’t- and don’t want to record how you can do it, because it took me soooo many times and a lot of rage. Don’t wanna go through that torture again. This video might help you guys though:
(Best I could find)
I recommend the following spots to do this:
-The Icon: barrier against villa caruso gate wall next to the trampoline trigger
-Landslide: Rocco apartment/edge of villa caruso gate wall below Rocco apartment
-The Author: edge of villa caruso gate wall below Rocco apartment
If you get stuck inside a wall, try to run towards the mansion. It helps sometimes.
Good luck to all of you.
