WARNING: I almost broke my camera following this step. If you are following these instructions in order to replace your lens, stop now. These instructions are incomplete, and misleading; you don't need to remove this piece in order to complete a lens replacement. What you're looking for instead is this: https://www.youtube.com/watch?v=fLxQC_55...
Mine too, these instructions leave out several crucial steps for making the repair. Step number 7 is not feasible and step number 9 is totally lacking in detail (it doesn't mention the removal of a crucial screw, and doesn't instruct you on how to ACTUALLY make the step). Garbage.... I'm not sure if my camera will ever work again
