I bought one of the refurbished EM5 ii when Olymus was running an extra 20% sale just before Christmas. I kept forgetting about the firmware update but finally thought I would do it this morning. The menu says the camera has the 1.2 version. Do I need to do each update in order to to get to the most current version? I tried connecting my camera using the Olympus cord and get a message that the computer is not recognizing a camera. What am I doing wrong?
