Wondered if anyone knew how long it roughly takes for the upgrade if you just take the camera to the service center? Can you pick it up same day or 2 days?
It's fast. For the 3.0 4K upgrade, it took about 1 1/2 days. I then went back for the 3.1 firmware update and Sony LA did it in 4 hours.
Also, calling Sony service number gets your nowhere as it's a call center in the Phillipines. I just drive to the Sony LA and they are very helpful and accommodating.
