The top of the pyramid has cover that can be lifted off
Below is the mirror which is held in by a tab.
Lift the tab with the spudger and pop out the mirror.
If you intend to reassemble the camera make sure the mirror is completely clean without any spots or fingerprints because they will affect the quality of your pictures.
Yes, after step 8 you will have the back case free then in the inside you will see the latches of the plastic plate that holds the strap, pry them carefully are 6, 2 on each side and 2 in the middle, in the middle of doing it myself have stopped since was no need for that so cannot tell you more.
RAW Fish: Get a terminal driver or other thin device, and wedge it where you can see a line between the outer casing and front panel (where it says “Polaroid” with the rainbow logo). This will need a bit of brute force, but you will be able to seperate a right-angle of outer casing, from the back of the flash, and another right angled bit full of electrics and the front panel. DO NOT touch any of this electrical gubbins - discharging the capacitor through your fingers will HURT. From here you can take out the circuit board and do with it what you wish.
Hi ! Thanks for your article ! I just bought a Barbie polaroid 600 ;) but unfortunately the flat wire between the camera the flash is disconnected (it dangles from the camera). I managed to remove the flash, that is no longer connected. Do you know how can I open the flash part to reconnect the wires ? Thanks ;)
