I had a completely cracked screen. No video.
The repair was simple and straightforward using the magnetic mat I purchased. Keeping screws organized is key. However, the part I received did NOT have the two bottom receptacles for the pentalobe screws. I'd be very upset if I didn't have a case to ensure the screen does not come off, and I would typically request another part, but ain't nobody got time for that.
Get the screw mat. Get a good tool kit.
