When it comes to PlayStation, there really is no better place to play. However, you’ll have to think of somewhere else to play if you get the CE-34878-0 error on your PS4! The error displays whenever you experience an issue with the game or application you’re trying to use. Fortunately, there are a few things you can do if you run across this issue. So, let’s go over how to fix PS4 error CE-34878-0.

Fixing PS4 Error CE-34878-0

Should you be experiencing the error on your PS4, try these two fixes to get you back in your game:

  • Update your PS4.
  • Initialize your PS4.

Update Your PS4

To update your PS4, you’ll want to follow these instructions after turning the console on:

  1. Head all the way to the right of the console’s menu, and select the Settings option.
  2. Now, go to the System Software option, followed by the System Software Update and Settings option.
  3. Here, select the Update System software option, and you’ll be notified if there is an update to be made.

Initialize Your PS4

If you need to instead initialize your PS4, then follow these steps:

  1. Make sure you create a backup of your PS4 as initializing it removes all the data.
  2. Once the backup is done, head into the Settings and go to Initialization.
  3. Here, select the Initialize PS4 option.

After following the onscreen instructions, you’ll restart your  PS4 and start it up again as though it were the first day you bought it. These fixes will also work if you are using the PS4 Pro.
