You skipped the part where you tore the wide lens ribbon from its circuit bard. There is small piece of the ribbon separate from the rest that is soldered to the circuit board preventing the lens from being removed with the ribbon intact. However, if you lift the lens and remove the three screws holding the metal plate to the back of the lens, you can then lift the metal plate and ribbon from the lens. You can leave the ribbon on the camera and the lens can be removed safely without damaging the wide lens ribbon. You could also de-solder the small tab on the ribbon, then remove the ribbon and lens without damaging the ribbon.
Opening cameras is more dangerous than most other electronics. If anyone here is going to do this make sure you know what a capacitor is. The flash capacitor in a camera can store a higher voltage than what comes out of the wall. This voltage remains after the batteries are removed until the capacitor is discharged. The black cylinder at 10:50 is the capacitor. You can get thrown across the room by touching anything in circuit with this capacitor if it is not discharged
