Using a heat gun definitely helps soften the adhesive for pulling off the contacts. When putting it back on, I heated it as well to that it would re-stick better. Used heat gun at 250F for a few seconds only. ALSO when putting back the home button, at first when i tightened the screws on the plate too much the button wouldn't click. I had to loosen the screws and kept testing to see what the right torque is to ensure it would click. I used loctite to make sure these not fully tight screws wouldn't come back out.

The screen that I got had a purple film on the back. Must remove so that the back looks like exactly the same color as the one original one.
