To resolve the issue, Sony suggests installing the system software update utilising safe mode. This article will show you a couple of troubleshooting solutions to help you resolve the PS4 error SU-42481-9.

Check PlayStation Servers.

First, you need to download the necessary files to update and ensure that your Playstation is connected to PSN’s servers. If you get error codes while updating the software on your PS4, it could mean there’s a problem with the servers.

To check the current state of their services, go to Playstation’s dedicated page. If PSN is unavailable, the best thing you can do is wait for their team to resolve the issue, as you cannot resolve server-related issues on your own. However, if the Playstation Network servers are working correctly, proceed to the next step.

Power Cycling your PS4

PlayStations have been identified to glitch for a long time. However, it can be easily remedied by power cycling the console. It’s an act of completely shutting down your devices and draining all of the power cables.

It forces the console to start up with all of its default configurations. 

  • First, turn off your PS4 device by pressing the power button on the front of the console.
  • Then, Unplug the power cord from the terminal once the console has been properly shut down.   
  • Now press and hold the PS4’s power button for 30 seconds to ensure that all power cables have been drained.
  • Wait for 4-5 minutes, and then leave it alone. After that, reconnect everything and try running the PS4. 
  • Now you may check the PS4 error SU-42481-9 went away, and then you can reconnect to the PSN network.

Check the Storage Space. 

 Although you won’t be able to update your Playstation 4 if you don’t have enough space in the drive, it’s a good idea to leave a 5GB to 10GB buffer on your hard drive in addition to the actual size of the update.

You can do this by uninstalling any useless software or games and then reinstalling them after the upgrade. You can delete games from your PS4 by following the steps below:

  • First, navigate to your home screen and search for games and applications that you may Uninstall.
  • Then, using your controller, highlight them and then press the Options button.
  • Select the Delete option from the side menu.
  • Finally, confirm your action by pressing the O or X button on your controller.

Now delete every game or application you did not need and after that, go back to check if the issue is fixed. 

Check Network Connection.

Sometimes unstable or slow networks can cause the issue while downloading the update. It may cause issues with the connection between your Playstation and PSN’s servers. Make sure your internet connection is working if you get a SU-42481-9 during an update. 

You can check the connectivity in PlayStation by navigating to Settings and then Network > Test Internet Connection, or you can do an internet speed test.

If the test implies that your network is slow or unstable, reboot your modem or router to re-build the connection with your service provider’s servers. Remove the power wire from your router and leave it unplugged for at least 10 seconds before plugging it back in.

After all the procedure is completed, you can reconnect all the wires and re-test the network test on your PS4 to see the problem is fixed. If the testing fails again, you may contact your internet service provider and ask them to fix it.
