PlayStation Error SU-30749-5 — What It Means & How to Fix It

What Does This Error Mean?

SU-30749-5 means a PlayStation 4 system software update failed to install. This can happen during an automatic update or a manual update attempt. The error means the update file was corrupted, the download was interrupted, or the console has insufficient storage space. Your PS4 should still be functional — the old system software remains intact when an update fails.

Affected Models

PlayStation 4
PlayStation 4 Slim
PlayStation 4 Pro

Common Causes

Corrupted update file downloaded due to a network interruption mid-download
Insufficient storage space on the PS4 hard drive to unpack the update
PSN servers experiencing instability during the update download
PS4 hard drive is failing, causing file corruption when writing the update
USB drive used for manual update is formatted incorrectly or has a corrupted update file

How to Fix It

Delete the failed update file. Go to Settings > System Storage Management > System > Update Files. Delete any pending update file stored there.

A partially downloaded or corrupted update file will fail every time it tries to install. Deleting it forces a fresh download.
Check available storage space. Go to Settings > System Storage Management. Make sure you have at least 10 GB free — PS4 system updates require extra space to unpack during installation.

Delete old games, saved data you no longer need, or captured screenshots and video clips to free up space.
Re-download the system update. Go to Settings > System Software Update > Update via Internet. Make sure your internet connection is stable before starting.

Using a wired Ethernet connection instead of Wi-Fi reduces the chance of a download interruption.
If the download fails repeatedly, download the full PS4 update file manually from Sony's PS4 System Software page on a computer. Copy it to a USB drive formatted as FAT32 in a folder named 'PS4/UPDATE/'. Filename must be 'PS4UPDATE.PUP'.

The USB update method bypasses PSN entirely and is more reliable when network download keeps failing.
If SU-30749-5 persists even with a USB update, the PS4 hard drive may be failing. Consider rebuilding the database from Safe Mode first, then attempting the update again.

Boot into Safe Mode by holding the power button until the second beep. Select 'Rebuild Database' and allow it to complete before trying the update.

When to Call a Professional

SU-30749-5 is almost always fixable at home. The most common fix is simply deleting the failed update file and downloading it again. If the error repeats despite good internet and enough storage, the hard drive may be failing — that requires replacement.

Frequently Asked Questions

Will my PS4 still work if I cannot install the update?

Yes, for the most part. Your PS4 will continue to work with the previous system software version. However, some features — and some newer games — may require the latest firmware. You should keep trying to get the update installed.

Can I be banned from PSN for not updating?

No. Sony does not ban accounts for running outdated firmware. However, PSN access may be temporarily restricted if your firmware version is too far behind the current version for security reasons. Keeping your PS4 updated is always recommended.

How big are PS4 system software updates?

Minor updates are typically 200 MB to 500 MB. Major version updates can be 1 GB to 2 GB. The full PS4 system reinstall file (needed for Safe Mode reinstall) is around 900 MB to 1 GB. Make sure you have enough free space before starting any update.
