I've made this repair three times so far, and it is only this last time that I realized that step 31 (peeling flex cable from shield) was/is not needed. If you are removing the whole shield anyway and relocating it to your new screen+digitizer, it naturally will come with it.

One word of advice. The magnatized phillips head screwdriver is your friend for removing and installing screws. Using it allows you to pick up and place screws with less chance of losing it. Using tweezers has caused those tiny screws to jump away from me like mexican jumping beans, and they can jump very, very far. There is only one screw that is not magnetic, it's near the compass, and is installed in the square sheild that covers the three flex cables. The screw is located at the north east corner of the shield.

If you have the tools and take your time, and read and watch the videos, this is a fairly easy and straight forward repair.
