In each of the flex ribbons there is a tiny hole just outside of the connector. In stead of possible damage from the tweezers try using a small dental pick to gently pull the ribbon out of the connector. It pulls from the center and didn’t seem to damage the ribbon in any way.

Very useful information and pictures, although with a couple of omissions noted in the comments. (Kind of like getting a recipe from your favorite chef who always seems to leave out one or two of the key ingredients.)

Eventually, if you go slowly, you will get all of the screws out. Just take pictures or make a drawing as you go along so that you know which screws go where when you reassemble. I learned quite a bit about what makes this lens jam and may not have to go quite so deep in to the camera the next time I’m trying to fix a jam.
