So I received a "refurbished" E-M1, yet somehow it only has FW3.0 installed, despite the fact that it's 3 revisions old and the newest edition is 4.1. I've read the instructions, downloaded the newest edition of Olympus Updater, plugged the camera in and it recognizes the current FW (3.0) as well as the newest version (4.1). I got through the process to initiate the FW upgrade, and I see a percentage update pop up on my computer screen. It makes it to about 16% before that screen disappears on my Mac and I'm just left with a screen that say "updating the firmware". My E-M1 rear LCD is just black, it hasn't said "OK" yet, and it's been about 15 minutes since I started the update. This seems excessively long IMO, at least compared to my experience with Panasonic cameras. Speaking of which, why does Olympus insist on this proprietary cable and an internet connection, compared to Panasonic which simply places a file on your SD cars, and it's handled that way? It's much easier IMO. Anyway, how long has it traditionally taken people to update the firmware on their E-M1? Does 15-20 minutes seem excessive?
