PlayStation Error Code CE-45739-3 — What It Means & How to Fix It

What Does This Error Mean?

CE-45739-3 means your PlayStation 5 failed to install a system software update. The update process started but could not finish successfully. This is a common error and can usually be fixed without losing any data.

Affected Models

PlayStation 5
PlayStation 5 Digital Edition

Common Causes

The internet connection dropped or slowed down during the update download
There is not enough free storage space on the PS5 to complete the update
The downloaded update file is corrupted and needs to be re-fetched
The PS5 was turned off or lost power before the update finished installing
A PlayStation Network server issue caused the update download to fail

How to Fix It

Delete the failed update file. Go to Settings > Storage > Console Storage > System Data, find any pending update files, and delete them. Then try the update again fresh.

A partially downloaded update file can block future update attempts.
Free up storage space. Go to Settings > Storage and check how much space is available. Make sure you have at least 10GB free before attempting a system update.

PS5 system updates require temporary working space beyond the update file itself.
Try updating via a USB drive. Download the PS5 system update file from PlayStation's website onto a USB drive formatted as exFAT, then install it manually through Safe Mode.

This method bypasses the internet download entirely and often works when online updates fail.
Restart your PS5 and router. Turn both off, wait 2 minutes, then turn the router on first, wait for it to fully connect, then turn on the PS5 and try updating again.

A fresh network connection can resolve temporary download failures.
Try updating in Safe Mode. Turn off the PS5, then hold the power button for about 7 seconds until you hear two beeps. In Safe Mode, select Update System Software.

Safe Mode gives the PS5 a clean environment to install updates without background processes interfering.

When to Call a Professional

If your PS5 repeatedly fails to update and none of the fixes work, contact PlayStation Support. In rare cases, a factory reset with a fresh system software install via USB is required. Sony support can walk you through that process step by step.

Frequently Asked Questions

Will I lose my games or saved data if I update via USB?

No — updating via USB only replaces the system software. Your games, saved data, and settings are not affected. The USB update method is safe and officially supported by Sony.

How long should a PS5 system update take?

Most PS5 system updates are between 1GB and 2GB. On a typical home broadband connection, downloading takes 5 to 15 minutes. Installation after the download usually takes another 3 to 5 minutes.

Is it safe to leave my PS5 in rest mode during an update?

Yes — rest mode is actually the recommended way to install updates. The PS5 will download and install the update automatically in the background. Make sure rest mode is set to allow internet connections under Power Saving settings.
