Opened the screen a little too hard and the ribbons ripped. What parts do I need to replace them with?

Usually people rip off one of the screen connectors for the display it’s the 3d touch and home button most of the time. You’ll need to replace the screen to fix that. If the top one got ripped that connects to the front camera the front camera would need to be replaced. Test the phone to make sure what is not working.
