Restart your console

The good old ‘have you tried turning it off and on again’ paradigm works here as well. Restarting your console or just about any device is one of the best ways to fix many seemingly random issues, including the PS4 CE-34878-0 error.


Disable any mods you’re running

If you’re running any mods installed through the Nexus Mod Manager, disabling them will likely resolve this issue. This may not work for you, but it’s worth a try. 


Try reinstalling your games

If you’ve recently changed storage drives on your PS4, the change can trigger the issue. You should try reinstalling the game you’re having issues with before moving on to fiddling around with your storage drives.

Do keep in mind that you’ll have to use PS4’s Safe Mode for this. All you need to do is boot into the console’s Safe Mode and select the Initialise PS4 option.

Rebuild your console’s database

The PS4’s Safe Mode has many handy options that can help resolve several issues with the console. One such option is the Rebuild Database, option five in the Safe Mode menu.

This restructures your drive so that your console can read it just like new again. This option can help you get around a bunch of other storage-related issues as well and potentially fix the error.

Update your PS4’s system software

If the above methods fail to get your PS4 up and running, you’re going to have to take charge and update your console’s software version yourself. There are two ways you can do this.

  • Using the Internet
  • Manually updating using a software file. 

We recommend trying out updating using the internet first, as updating manually requires you to make sure you’ve downloaded the right update file and placed it properly on the installation media.
