With the retention ring off, you can advance the cable moulding into the housing, and the entire camera subframe assembly should freely disengage from the outer shell.

The entire cable may then be pulled outward, through the outer housing/shell port where the cable retention clip was fastened. (The white plug can be slightly manipulated to fit through.)

Fixers replacing the entire cable may choose to solder a new JST GH connector to their new cable before disassembly, reducing the time the camera sits in pieces. (Reuse the original ground wire for the cable sheath/shielding.)
