Hmm... my Blad-totin' friend and I (the more technichally inclined - I think) are in Pondicherry, India, at least five hours from the nearest shop and have a similar problem.
The lens is off and will not mount. If this matters, the lens is an 80mm prime, and after any attempt to rotate the winder on the bottom of it, even several turns, it will snap back to its original, shut position.
The body is jammed - the shutter won't fire. We tried loosening and tightening the silver screw, and it allowed us to fire and, but the lens still would not mount, and we could not fire again after retightening it. Any advice? Try the full process from the link on our own? Trust the instructions to a watch stand?
