pollux, If I remember correctly you must have film loaded for the shutter to fire. In the manual was there something about that? I have mine packed away and it's not handy right now. If you have the mirror back in the right position and a new battery load some film and take some photos. I don't think you have a problem that will need a trip to the repair shop. I had a similar situation some few years ago with just about the exact same circumstances. I think in the manual there is a reference to using the same tool that reset the mirror to be able to trip the shutter without film loaded. If you didn't force anything you didn't damage anything. Good luck with it. It's a super fine camera if you have any other questions or need any help just PM me.
