    • Remove the front panel by pulling away from the side with the lever.

    There is another loose part here that can come off on the side of the latch. It's also off in the picture. When reassembling, make sure to reconnect it to the spring as well, otherwise the back panel opening mechanism will not work correctly.

When reassembling, make sure to attach the spring shown in step 8 to the film back release mechanism. I missed this the first time I reassembled the camera and the release/close slide would not automatically close like it did before. I found keeping a finger over the bottom post and using the SIM removal bit to stretch the spring to the top of the slide was very useful. Overall great guide! Thanks for posting!
