The thread you were referring above and its questions are valid for Garmin gps devices, not applicable to a Virb camera.
Btw try this.... take the memory card out and replace with either another freshly formatted one or format the one that was in there.
The software update copies the files to that card and when you switch the VIRB back on it installs from the memory card.
If something failed during the update, may be file is corrupt in sd or not present at all.
Be sure to fully insert usb cord , must force it a bit to fully insert.
