Well, here are some photos of the camera and believe me or not it is working perfectly, manually.
The problem with the aperture was a small spring that keeps the aperture opened that need replacement. And the shutter blocked was just because somebody already tried to repair and putted a long screw instead of a shorter one and this screw was preventing the shutter to work only when it rotates to infinity. This caused the shutter release to be actuated and no further movement was possible. Just a small screw that perhaps disappeared and was replaced by a longer one. One of the two screws that sustains the black waist around the distance crank ring.
