$140, I called this morning...
I tried the eos utility. It doesn't bypass the card. It writes to it.then the camera upgrades from the card still.
I appreciate the quick responses, thanks guys.
Was that quote for just cleaning or a problem loading the firmware? There is a difference, because with a cleaning they upgrade the firmware free, but for troubleshooting a problem your going to get a higher quote. Of course if their is a problem that they discover during cleaning and the firmware update, then the price would get higher. But that would also mean there is a problem with the camera that needs fixing.
I doubt you qualify for CPS as mentioned in a post above as you need a certain points total of professional lenses and bodies. But it's only $100 and they include something like 6 cleanings in that price.
Have you done a reset of the camera? If that does not help, pull all batteries, including the little coin battery. Then set the camera date/time and try again.
Another thing to try is to get a hold of the current firmware version and try using that. You should get a message indicating it's up to date. I'm sure that version is available as I've seen some postings on similar stuff for the 5D3. But, do not go backwards as that can and has caused issues reported by someone recently giving that a try.
Also, how are you getting the firmware file onto the CF card? There have been issues with files being corrupted via CF card readers - so maybe another reader?
