I think I unfortunately broke my Rollei 35 XF. I wanted to load a film but it was really difficult to advance the lever. I think I pushed it too hard and now the lever is loose and it won't advance the camera to take a picture. Is there anyone who can help me with this problem? I also wanted to take of the top part of the camera to see if there's anything wrong but I can't manage to loosen the small circle on top of the advance lever. Any tips or tricks for that? If my explanation isn't clear enough, below a video to show the loose advance lever. Thanks in advance!
