I reviewed the excellent fixit instruction on Logic Board Replacement (6s Plus) and decided to give it a try but could not get past step 12. When I tried to lift the screen, the home button and the metal backing for the screen remained stuck in the phone. The home button cable (which is attached to the screen) prevents me from lifting the screen to no more than 1/4 inch. How can I get the home button and the metal screen backing free from the phone? FYI, I did remove the two 3.4mm pentalobe screws.
