I was going to add a response once I had fixed my own repair, but haven't gotten around to it. The heatgun and an exacto and plastic spudger easily took out the broken piece. Unfortunately, it also popped the camera lens cover and part of the flash assembly out with it, which I had to carefully remove and put back in with the new part. I used some 3M ATG tape on the back of the glass, and carefully put it in with the camera/flash parts in place already. Everything went fine except for two things:
- There are now a few dark spots on my pics. I assume there was some dust that got trapped on the lens, so be very careful about cleaning the lens and cover before reassembling!
- The ATG tape is slightly too thick, so the glass part extrudes just a bit from the aluminum it borders on. Not a huge deal, but noticeable.
I am going to order the thinnest ATG tape I can find and heat gun it again eventually to get the dust out of the camera. Hopefully I can get the glass back out without breaking it. :)
