How To Fix Black Ops Cold War CE-34878-0 Error | PS4 | NEW 2021!

We’ve got reports of some PS4 players experiencing the CE-34878-0 error code when playing COD Black Ops Cold War. If you are also getting the error and you have no idea where to begin your troubleshooting, this guide should help.

What does CE-34878-0 error code on Black Ops Cold War mean?

CE-34878-0 is a common error code in PlayStation 4 consoles and it typically indicates that the game has stopped working unexpectedly. This is a general error so there’s no single trigger for all cases. 

Some PS4 users may encounter this error due to a random game bug while some may have it on their console due to a corrupted software, hard drive, or a malfunctioning hardware.

For many who come across this error, the game crashes but then returns back to normal, usually after an update. 

What are the reasons for Black Ops Cold War error code CE-34878-0?

If you are getting the CE-34878-0 error code when playing Black Ops Cold War, it may be due to one of the factors below.

Game develops an error randomly.

Some games, especially newly released ones, may have an unhealthy dose of bugs. Most of the time, such bugs are fixed as the developer discovers them, or after they’ve been reported. 

If you only experienced Black Ops Cold War error code CE-34878-0 once or twice, it’s probably just a random occurrence. 

What you need to do right now is to ensure that you update the game and the PS4 software.

PS4 software is outdated.

Speaking of PS4 software, some games may crash at random if the console is running an old version. If you are unable to play online or if Black Ops Cold War Multiplayer is not working, the most likely reason is old or corrupted firmware. What you must do is to close the game and manually check if your PS4 needs to update its software first.

Game saves or files are corrupted.

Some Black Ops Cold War players have reported to us that their game started working again after they deleted and reinstalled the game. This suggests that the main reason for their problem may be bad game files. 

HDD issues.

A small number of PS4 users may encounter error code CE-34878-0 on multiple games because of a more serious problem with their storage device. 

You should check the health of your PS4 hard drive if you’ve already checked out the rest of the factors as mentioned in this guide.

How to fix Black Ops Cold War CE-34878-0 error (easy steps)?

Now that you have an idea what the causes are for the CE-34878-0 error, let’s see what you need to do exactly to fix it if it occurs when the console is running the Call Of Duty Black Ops Cold War.

Keep game and PS4 firmware up-to-date.

Installing updates, for both your games and your PS4 software does not take much time and effort. All you have to do is to confirm the prompt to update and you’re good. 

However, you can also check for software updates manually any time if you think that your PS4 may be running an older software version.

Restart your PS4.

Rebooting a problematic system is an effective yet simple way to fix bugs. When a reboot is done properly on a PS4, you can also clear the system cache, which is a collection of temporary files that the system needs to load things quickly. Sometimes, a bad system cache is the root of slow performance or crashing problems when playing.

To ensure that you purge the system cache and force the console to build a new one, follow these steps:

  1. Turn off the PS4 normally using the Power button or the controller.
  2. Unplug the power cable from the power source (outlet or power strip).
  3. Wait for 30 seconds.
  4. Start the console back up and check for the problem.

Repair PS4 database.

For those who may have issues with corrupted game files, there are two things that you can do. One is to delete your game data locally (be sure that you create a back up in the cloud before doing this) and the other is by rebuilding your PS4 database.

How To Fix Corrupted Data Error On PS4

Reinstall COD Black Ops Cold War.

If the error continues at this point and the game has become virtually unplayable because of it, you’ll need to delete and reinstall Black Ops Cold War.

Before you go ahead with this solution, ensure that you keep a copy of your campaign saved files in order not to lose them. If you don’t play the single player campaign mode, then, you can just delete the game and all associated files from the system. 

Use another hard drive.

If you are one of the unlucky players with a bad HDD or hard drive, chances are other games and not just Black Ops Cold War will also crash and show the annoying CE-34878-0 error. 

Some hard drives may fail prematurely due to wear and tear while others may encounter serious file corruption issues. If you suspect that you have a hard drive failure, which can also be indicated by other errors or severe performance issues, try to use another hard drive, or simply replace the current one.

If you are only having an issue with games, try to use an external hard drive and install Black Ops Cold War in that one.
