I am happy to report that I was able to do this repair successfully. The hardest parts were removing the glass back (covering the camera) and prying the outside case away from the rest of the phone unit. I definitely purchased the “Technicians Razor Set'“ and am glad I did. I used all the tools listed in the guide (most of which I had earlier from a larger kit). I used the blade that is a rectangle that has a sloping / graded end so that it is real thin at the point of entry and allows you to pry a bit. I tried with the standard “exacto-knife” type end but it didn’t seem to do the trick for me plus I felt it was dangerous to push with force with something that sharp.

Use a heat gun. If you have a hair dryer that gets pretty hot that might work as well. A cheap heat gun makes this SOO much easier. I also happened to have one of those laser surface temperature readers and got the glass up to about 180 Fahrenheit which works well. I got the plastic bottom piece to about 150 to get the glue underneath gooey.

While I performed this step, the three ribbon cables from the next step came up attached to the metal plate.

While I was performing this, the three flat ribbon cables were stuck to the metal plate and came up with it. Watch out for that possibility.
