I have now upgraded my A7IV two versions using the firmware on SD card option that was introduced recently. First from 1.10 to 1.11 and now finally from 1.11 to 2.0.
Before I move on I can confirm I followed the instructions exactly.
I made sure the battery was fully charged and copied the downloaded firmware file to the root of the SD card. No other firmware was present on the card in both instances.
Everything went smoothly until I noticed five slow flashes followed by seven (yes, seven, not six as Sony states is the error "code" when an update fails) quick flashes. I left the camera for another five mins, but no change. I then turned the camera off and removed the battery for approx 30 seconds. I powered the camera back on and the update finished successfully after a few mins. The steps above were required for both version upgrades I have performed on my A7IV.
This experience when upgrading is of course quite alarming. Bricking the camera seemed like a likely outcome both times.
I just want to mention this in case others experience similar problems with their A7IV.
Finally, I have not had the time to shoot more than ten pics or so no info on the experience on the 2.0 firmware.
PS; Only thing that triggers my OCD on 2.0 is that, when powering the camera on, for half a second the green "Auto" LCD screen (happens when using the viewfinder as well) options are shown before loading the options for Manual, or Aperture priority etc.
