This was one of the most difficult repairs I have done, but it worked. First off I absolutely could not get anything except a tiny Flathead screwdriver wedged in to the glass to pry it up, which cracked the glass even more than it already was, but thankfully I was replacing the back glass as well. The battery was also glued in unbelievably well, and the battery ended up bending pretty bad when I pried it out, even with a lot of extra heat.
Overall a massive pain in the rear, but I got it all working properly now thanks to the video. I used a Wagner heat gun for this, I don’t think a hair dryer would be sufficient!
