Where do I get a logic board?

I like the tear down specialist. Pretty hands. Voice is very easy to listen to. Easy to follow as she disassembled the iPhone 8 plus. I had a good view of the whole process. Great job.

Not strong enough. Get another piece of drywall and cut it 2" larger than the hole all around . Turn drywall upside down and with a knife score the paper slightly smaller than the hole and bend back the drywall and peel off piece but leave the top layer of paper attached. Do that on all four sides and you will have a two inch flap all around edge of repair with drywall in the middle. Put patching compound on edge of the piece of drywall and flap and some on wall at hole. Place piece of drywall in hole and with a 6" putty knife scrape out excess putty by dragging putty knife from center of repair to outside of damaged area. Continue doing this until paper flap is smooth against wall with no excess in a lump underneath. When dry, add more putty in a circular motion around the paper flap until smooth. When dry you can sand it or use a wet sponge that is wrung out really well and smooth it out with no dust. Now paint it.
