PlayStation Error Code CE-43350-1 — What It Means & How to Fix It

What Does This Error Mean?

CE-43350-1 means your PlayStation failed to install an update for a game or the system software. This usually happens because the download file became corrupted, your storage is full, or there was a connection problem while the update was downloading.

Affected Models

PlayStation 4
PlayStation 4 Slim
PlayStation 4 Pro
PlayStation 5

Common Causes

The update file downloaded incorrectly and is corrupted
Your PlayStation does not have enough free storage space to complete the installation
Your internet connection dropped partway through the download
The game's saved data or installation files are conflicting with the update
A PSN server glitch caused the update package to be delivered incomplete

How to Fix It

Delete the failed update file and re-download it. Go to Notifications > Downloads, find the failed update, press Options and select Delete. Then go back to the game and select Check for Update to download it again.

Corrupted downloads are the top cause of CE-43350-1. Deleting and re-downloading is the fastest fix.
Check your available storage space. Go to Settings > Storage and see how much free space you have. Updates often need extra temporary space during installation — you may need more free space than the update's listed size.

PlayStation updates can need up to double the stated size during installation. Delete unused games or videos if you are low on space.
Restart your PlayStation and try the update again. Hold the PS button and choose Power > Restart PlayStation. Once restarted, go to the game and select Check for Update.

A restart clears any temporary installation errors that could be causing the update to fail.
Try updating from Safe Mode. Fully power off the console, then hold the power button until you hear a second beep. Select 'Update System Software' from the Safe Mode menu to try installing from there.

Safe Mode bypasses many normal system processes that could be interfering with the update installation.
For game update failures, try deleting the game completely and reinstalling it fresh. Press Options on the game tile, select Delete, then reinstall from the PlayStation Store or your disc.

If the existing game installation has a problem that blocks the update, a clean reinstall will fix it.

When to Call a Professional

If this error persists after all fixes and is caused by a specific game, contact the game's developer. For system software update failures, contact PlayStation Support at support.playstation.com. They can walk you through an offline update process using a USB drive.

Frequently Asked Questions

Will deleting the failed update delete my saved game data?

No. Deleting an update file from Notifications only removes the downloaded patch — not your saves. Your saved game data is stored separately. However, if you delete the entire game, your saves may be deleted too unless you back them up first.

How much free space do I actually need for an update?

As a rule of thumb, you need at least double the update file size free on your drive. For example, a 5 GB update may need 10 GB of free space temporarily during installation. Once the update installs, the temporary files are deleted and you get that space back.

Is there a way to update my PS4 without an internet connection?

Yes. You can update using a USB drive. Download the update file from PlayStation's official website on a computer. Copy it to a USB drive in the correct folder structure, plug it into your PS4, then use Safe Mode to install it. PlayStation's support site has full instructions for this process.
