After the now-you-see-it-now-you-don't v1.2 firmware for the E-M5, there is a version 1.5 available. If you have firmware v1.0 or v1.1 you need to update to v1.3 first before updating to v1.5. I think that for anyone who successfully updated to v1.2 previously they need to go to v1.4 then v1.5. The two headline features are the enabling of IBIS during video for adapted lenses, and a big reduction in the "hum" that the IBIS makes during normal operation. The old, louder hum now only occurs when the shutter is half-pressed.

From the Olympus Imaging Australia webpage:

I did the update to 1.2 during the window it was available. Not sure why I did it since v1.0 was working okay for me. I still don't get how the bricking happens. I originally understood from the PEN upgrade process that the firmware is downloaded to the tethered PC and, then when completed downloaded from the internet, it is pushed to the camera body. The only problem there was if your USB was disconnected (or USB hub failed, etc.) while the firmware was upgraded on the body.

The bricking that I read about on a couple OM-Ds seemed to indicate that the body upgrade process began before the file was 100% downloaded from the internet, so an interruption in service could cause an issue?

Also, I believe that the update will fail if your internet connection drops out during the download. I think that the download should occur independently of the actual camera firmware update.
