    • Remove screws.

    • Disconnect connectors for Lens assembly

    • Carefully disconnect the tiny cable

    • Next step is removing the PCB. I made the mistake not to take care about the battery compartment switch. If you are not careful, the black lever will break off. Not a problem though, because then the camera will work also with opened battery compartmen

    • Remove main PCB by slightly bending outward the cover for the jack with fingernail. Now lift the PCB slightly upwards.

    • Look under the PCB, there is a connector that needs to be separated by means of a small screwdriver or spudger.

    • Re-attaching the connector is not easy. I used a small screwdriver to carefully press the connector back in place.

    • This is not the official method to do this. Normally the Top cover and several other parts need to be removed too.

    • Measure continuity with a multimeter on SD-card slot write protect switch.

    • If it is not working, short the two points with a bodge wire, so write lock is disabled

    • Another possible fault is a broken soldering joint holding the case of the SD-card reader in place.
