Just completed the replacement of my screen. The guide was very helpful as well as watching the video. To keep all the screws organized, I just drew a large picture of the inside of the phone on a piece of paper and made loops of clear packing tape and put them over the areas where I was going to remove parts. That way I could make sure each screw went back into the proper place. Took about an hour from start to finish. One tiny glitch, the screen isn't perfectly snugly down at the top of the phone, there is a little play. It is tight everywhere else. Oh well, no biggie. All good now.
