How to fix error CE-34878-0 on PS4?

Errors of the PlayStation 4 are little described and often difficult to fix, since the developers from Sony, if they give comments on them, are only brief ones, which do not give an exhaustive picture of the problem. One of these errors is CE-34878-0, which users complain about when launching games or at a certain point in the passage. The problem is unpleasant in that it does not allow you to comfortably use the console for its intended purpose. The good news is that usually the CE-34878-0 error can be fixed in one of the following ways.

Working methods to fix error CE-34878-0 in PS4

We will start with the simplest methods and gradually move towards more complex solutions.

Method 1: update the game and console software

If the game console or the game itself needs to be updated, a similar error code CE-34878-0 may occur. In this case, it is not difficult to fix it, it is enough to check for available upgrades and install them. Initially, we recommend that you complete the PlayStation 4 update procedure.


  1. Open the PS4 console settings.
  2. We go to the tab “System software update”
  3. We are waiting for the completion of the search and confirm the start of the installation.

The update usually takes place without user intervention, but it takes some time. After 10-15 minutes, the console is ready for use again. Now is the time to check if the CE-34878-0 error is still there or if it has already been fixed.

If the solution does not work, you should take care of updating the game. To do this, on the PS4 start screen, select the problematic game and click on the “Options” button. We select the option “Check for updates”. If required software is found, the console will download and install it. It is worth re-checking, often already at this stage the error CE-34878-0 recedes.

Method 2: reinstall the game

Damage to game data can also often cause error CE-34878-0. The most effective method in this case is to delete all of its files and reinstall it. It is only worth backing up your data beforehand (in case of problems with offline play). If we are talking about an online application, all data is stored on the server, so it is not necessary to make a backup. The Copy to USB Drive option is located in Settings on the System page in the Application Saved Data Management subgroup.

Method 3: turn off the PlayStation Camera

The solution is suitable for PlayStation 4 users who equip it with a PlayStation Camera. This accessory sometimes has an undesirable effect in the form of error CE-34878-0. The first step is to disconnect the camera from the console.

  1. Open “Settings” and go to the “Devices” directory.
  2. Select “PlayStation Camera” from the list.
  3. Turn off the ability to recognize faces.
  4. Disconnect the accessory from the console.

If the error persists, then it is not the problem. Is the problem gone? It is worth trying to reconnect it and check, maybe the random failure will no longer appear.

Method 4: change the hard drive

A number of users started to face the CE-34878-0 error after installing a new HDD instead of the original drive in the console. Returning the original disk will help fix the problem. Then you will have to experiment. Perhaps formatting the drive will help.

Method 5: reset the settings to the factory state

If nothing helps at all, you will have to resort to a more radical method – factory reset. All of these parameters will return to the state they were in when they left the factory. This action may lead to undesirable consequences, but it almost always helps to fix the CE-34878-0 error. It does not lead to the deletion of personal data, so you should not worry about information and games.

How to do:

  1. Go to “Settings” in the “Initialization” section.
  2. Click on the “Restore default settings” option and follow the wizard’s guide.

Only as a last resort you will have to initialize the PS4. The procedure will lead to the complete deletion of data. However, most likely it will not come to this and the reader will be helped by one of the methods described earlier.
