Another great guide. definitely one of the more difficult repairs that I've done but if yours careful, follow the guide, and isolate your screws and parts, it's simple.
I use a deviled egg travel tray to keep my things divided. it's wide and has a lid if you need to stop in the middle of a repair. keep the animal hair and dust out at least.
Best advise is to disassemble and reassemble. probably just a screen contact unless you ripped a ribbon. never a paper weight. just a learning experience
Great guide. I have no expertise and this took me much less than an hour
it is just a little bumper that goes against the speaker
