The way you do a fakie 360 shove it is by being able to do a regular shove it, either front side or back side, for starters. Now you also need to be comfortable rolling fakie. It's very important that you get a nice, big scoop on that turn, so instead of getting just that 180 degree turn, you get a nice, full 360. As usual, you want to land directly over the board. It's very important that you toss the board enough, so you want to get a nice, big scoop and a lot of pressure.
You wan to keep your back foot back and your front foot forward. So try to do that a few times, just staying on the ground without your board, keeping your back foot back and your front foot forward. If your used to doing shove its, you might want to put a little bit more pressure into your tail, just so you have a better feel for how to do this trick. Same for the 360 no comply or the no comply big spin. You really want to put a lot of pressure into that turn, so that way you can actually get and stick the landing. And that's how you do a fakie 360 shove it.
