To remove the bumper, you need to remove the grille first (open the hood, 2 screws are on top, 2 are in the grille). Then remove the front signal lamps, in the vid above they remove the marker lights, the bumper is easier to remove if you remove the signal lamp using the same torx screwdriver. Now the bumper is held on by a bunch of plastic rivets, some on top, some on the bottom and some in the front wheelwells. Some of them can be re-used if you are careful when you remove them. The bumper is held on by some clips that stick up under those signal lights, thats why I said to remove em. There is a slot on the top edge of the bumper, that goes UNDER that light that fits into the clip. Yours is broken on one side in the pic, I fixed that with the same 3M structural adhesive. You have to lift the bumper up and slide it off those clips. Removing the black piece that all the lights fit into is a bunch more screws. Its kind of a pain but not really difficult.
