The lack of explanation for the back glass adhesive is pretty bad. It's a major reassembly step that is just completely skipped over with completely no mention and kind of complicated in comparison to the rest of the process IMO. It really needed to be in here so I've added a comment with regards to it. The generic adhesive instructions that have been posted in the comments aren't helpful for this at all either. Outside of this major instruction flaw the rest was solid and spot on. The phone has been fixed and Is working properly once again for way less than having someone else fix it.

REASSEMBLY ADHESIVE: This is the step during reassembly that you'll want to set the back glass adhesive strip on (before you reattach ribbons). Set the adhesive strip into the body of the phone with the red tabs down (toward the body of the phone, it will simply rest inside the lip of the phone body). Press the back glass onto the adhesive strip to set the strip onto the back glass, lift the back glass back out of the body of the phone. Next reattach the ribbons, test functions, reattach connector covers, peel red adhesive cover off of the adhesive (on the back glass) then set the back glass into the phone lip. This could have been explained far better but was skipped over and the generic adhesive instructions posted in the comments are useless for this.
