I completed this repair but would recommend replacing the bracket as well as the lens, really they should be sold bundled since you’ll destroy the bracket to get the lens out.
OK, so I was able to complete this step, but it’s not for the faint at heart. Since the bracket is soldered to the lens cap from opposite sides I had to use a board and vice to attach the bottom of the iPhone to my bench, leaving the corner with the camera exposed and hanging over the edge. The I used a hammer and screwdriver to break the solder and poke the crumpled bracket through the hole with the lens still attached. Once I forced the broken lens out I was able to use tweezers to spectate the bracket from the lens. I salvaged the bracket and bent it back into place enough where it’d fit back into the phone and was able to replace the lens and put everything back together just fine. But it wasn’t nearly as easy as described. That solder is a real bugger.
I was able to complete this step but it wasn’t pretty. The rubber cover of the bracket is glued to the bracket, comes off but it was a bit deformed. The problem is the bracket is soldered to the lens cap, making it impossible to remove either without force. Truly crap design from Apple IMO.
