How can I access the components inside my iPhone SE? (Alternate layout

I just unscrewed the bottom of the phone, and popped it open with a suction cup. However when I look at the inside, I don’t have the same layout as can be seen in the videos on this website. Their is a metalic shield plate covering the battery and the mother board, as well as a black border at the top and bottom. There are what seems to be screws but none of the tools I have can turn them. Any guides or info that can used to assist me?

edit: ok, so i found what happened! The lcd screen split in half… the protective shield stayed down with the back of the phone
