Camera after accident question

I have crashed my p2 vision plus, broke the ribbon cable. I have installed a new ribbon cable, made sure the sensor is lined up as per youtube video with a but of glue on the shaft.... The camera is still going crazy.

Now my question what is the correct position of the shaft that is holding the actual camera? There is a screw which holds the camera from sliding off. One side of the shaft is round and the other side is straight. The screw gets screwed into the straight part or the oval part?

What else can make the camera go out of control? I have searched, and seen every possible video online.

I have followed this video and did all steps, now everything lines up. But the camera still goes crazy. https://www.youtube.com/watch?v=Y5tUAy5U...

Please any help will be good.
