If Error (CE-34878-0) does appear again, but this time it has taken longer than before, it means you’re on the right track and about to figure out why it happens. You’ll need then to turn off PS4 again, but this time wait 5-10 minutes before turning it back on.
Now, look carefully after you turn on the PS4, does Error (CE-34878-0) take an even longer time than before to appear, or nothing has changed?
If it does take longer, it probably means you have overheating issue with PS4.
Solution #2: Move Your Game to the Internal System Storage
If you’re encountering PS4 Error Code (CE-34878-0) on a game/app installed on an external HDD, the problem then might be in the external HDD itself. It’s strongly recommended to move your game to the internal storage of PS4 and try it from there.
Solution #3: Update PS4 System Software
Updating PS4 system software can fix many issues related to the console’s performance. For that reason, it’s imperative to keep your console up to date with the latest version of system software.
To start the process, just do the following:
- Go to the PlayStation home screen, select Settings.
- Choose “System Software Update” to install the most recent update.
- Your PS4 will check for available updates for its system software and install any that are available. Let the console do its thing.
- After the installation is successfully accomplished, restart the PS4 and check that specific game/app that caused the error.
Now, if this has not fixed the error and you still see that annoying message, try the other solutions.
Solution #4: Update the Game/App
Sometimes the failure occurs from the game/app itself due to deficient/improper coded file. That’s why the manufacturers keep releasing updating patches for their games/apps to fix these issues.
To do that, simply follow these steps below:
- Go to the PlayStation Home screen.
- Highlight the game affected by this problem.
- Press the Options button on the controller.
- Highlight and select Check for update to check for game updates for the affected game and install any that are available.
Once the process is complete, try to launch the game/app and see whether the problem has gone or not yet.

If a PS Camera is connected to the system, remove it and reboot the system, then turn off Enable Face Recognition.
- From the PlayStation 4 home screen, select Settings.
- Select User.
- Select Login Settings.
- Uncheck Enable Face Recognition.
Solution #6: Disable Mods
Some gamers confirmed that disabling recently added mods helped them repair this error code. While this solution might not work for all users, it is worth trying it out.
Solution #7: Change PS4 Display Settings
It has been reported by some users that changing the video output settings from Automatic to 720p would fix this problem. Other resolutions may work fine as well. So, try all of them and see what suits you best.
By default, the PlayStation 4 will automatically manage video output settings, but if you want to use a specific video resolution:
- Go to Settings > Sound and Screen.
- Select Video Output Settings > Resolution.
- Select your default resolution:
- 1080p (the default resolution for most PS4 games)
That’s it all.
Solution #8: Check PS4 Hard Drive
As the official fix suggests, if you have recently changed the stock hard drive of PS4 and then started seeing Error (CE-34878-0), try to install the original hard drive and see whether this fixes the error or not. In many cases, this error occurs with the original/stock hard drive of PS4.
If you’re not considering upgrading the PS4 internal hard drive with a more powerful drive any time sooner, or you have already done so but faced Error (CE-34878-0), the hard drive may malfunction and needs service.
The hard drive failure is a common incident that every savvy must have encountered. It happens due to varied reasons, especially the presence of bad sectors that hinder the hard drive to operate properly. Additionally, if the PS4 HDD doesn’t make any kind of noise (clicking/grinding), there’s a big chance to fix it. Check out this article to learn more about PS4 hard drive failure and how to repair it.
The PS4 internal hard drive might be working fine and flawlessly, but there is a sort of power shortage in your PS4 that prevents the hard drive to run properly. The cheapest workaround for this issue is to replace your PS4 HDD with an SSD, because SSDs use less power and are more resistant to power instability.
Solution #9: Rebuild PS4 Database
Sometimes rebuilding the PS4 database can resolve this problem and fix that error. It’s a very easy process to fulfill, but it may take a few hours though.
To successfully rebuild the PS4 database, please follow these steps:
- Turn off the PS4 completely (i.e. not in Rest Mode).
- Once off, press and hold the power button. Release it after you’ve heard two beeps: one when you initially press, and another about seven seconds later. This will boot the PS4 into Safe Mode.
- Connect a DualShock 4 controller with a USB cable and press the PS button on the controller. If the PS4 isn’t recognizing the controller, you may have attached a ‘power only’ USB cable – use the one that came with the controller.
- Select the option Rebuild Database. It will warn you that it may take hours.
Solution #10: Delete The Game and Redownload it
Some of the core files of the game might be corrupted/damaged causing the PS4 system to generate error code CE-34878-0. If you’re getting that error on a specific game whereas other games work flawlessly, then you may want to delete that game and all its saved data and download and install it again.
It’s strongly recommended that you store your game saves and any important data on a USB storage device before carrying out this step.
Solution #11: Factory Rest PS4
To reset PS4 to factory settings, you have to perform PS4 initialization. This feature can resolve so many issues related to the performance of PS4. So, every PS4 user must know how to do it the right way. Just in case.
Before we begin, you should know that a factory reset completely wipes the console’s hard drive and can even remove its system software. In other words, it will delete everything on your PS4 HDD, including your games and PS4 operating system.
It’s the penultimate resort when a software glitch stops your PlayStation 4 dead in its tracks, particularly when booting up or when you want to make sure the console no longer has your data on it.
You should back up any data you want to keep, such as images and video, to an external device or to the cloud. In order to back up data using the cloud, you’ll have to have a PlayStation Plus account.
There are two ways to reset your PS4 — From the console’s dashboard or in Safe Mode if the console is having boot-up issues. For PS4 error (CE-34878-0), you need to choose the full initialization.
Do not turn off your PS system during initialization. Doing this might damage your system.
- Go to PS4 Settings > Initialization > Initialize PS4.
- Select Full.
- Follow the instructions to complete.
- After finishing, restore all your backup data, and reinstall the games and applications.
- Try the games to see if it works now.
Solution #12: Clear the PS4 CMOS Memory

You need at this stage to clear the PS4 CMOS memory in order to set things right. This process might be kind of difficult and time-consuming because you need to open up the PS4 case and carefully remove the PS4 CMOS battery.
