Hi I have the OM-D and was using the Olympus updater programme to update the attached Panasonic 45-175 'X' lens to the latest firmware when my computer crashed. It seems like the firmware has been wiped from the lens such that my camera won't recognise the lens now. Reading up on it, it appears that to reinstate the firmware I will have to do it the Panasonic way and attach the lens to a Panasonic body and re-install the firmware from an inserted SD card. You cannot do this with an Oly camera. Hence my request for help! If you can help or know the solution, please can you contact me.
