What it means
CE-108889-4 means the console lacks the system software version it needs. Sony gives three routes: update over the internet (restarting network equipment and console if there is an error), download the file to a USB drive from a connected computer, or update from a game disc that holds a newer version, which shows the process on screen. The route depends on whether the PS5 has a connection. The code indicates no fault.
