I too have had problems after upgrading the firmware on my xe2. I followed all the instructions carefully and after the upgrade the camera worked fine until I turned it off. When I turn it on again it will either do nothing, turn on for a split second (and I believe show a battery exhausted warning?) or actually work. Last night I turned it on and off successfully 3 times before it did nothing. I have checked the batteries and they are fine - charged.
I can take the card out and the battery out and wait a few minutes then put them back in and sometimes it will start but usually not.
The only thing I question at this point is the card. I had it in a Nikon camera and then switched it to this camera. I did format it and reset the resets, etc.
I'm very puzzled to say the least. Any thoughts?
