SU-41350-3
Sony PlayStation
Severity: CriticalWhat Does This Error Mean?
The SU-41350-3 error means the system update file on your USB drive is corrupted, missing, or saved in the wrong location. This error appears during Safe Mode when you try to update or reinstall the system software from a USB drive. It is critical because your PlayStation may not boot normally until the update is applied correctly.
Affected Models
- PlayStation 4
- PlayStation 4 Slim
- PlayStation 4 Pro
- PlayStation 5
- PlayStation 5 Digital Edition
Common Causes
- The update file was saved in the wrong folder on the USB drive — it must be in PS4/UPDATE/ or PS5/UPDATE/
- The update file was renamed incorrectly — it must be named PS4UPDATE.PUP or PS5UPDATE.PUP in all caps
- You downloaded the smaller update file instead of the full reinstallation file when a full reinstall is required
- The USB drive is formatted in the wrong file system — it must be FAT32 or exFAT
- The download was interrupted and the update file is incomplete or corrupted
How to Fix It
-
Format your USB drive as FAT32 or exFAT. On a Windows computer, right-click the USB drive in File Explorer, select Format, choose FAT32 or exFAT, and click Start.
NTFS format will not work. If your USB drive is larger than 32 GB, you may need to use exFAT.
-
Create the correct folder structure on the USB drive. For PS4, create a folder called PS4, then inside it create a folder called UPDATE. For PS5, create PS5 > UPDATE.
The folder names must be in ALL CAPS. The path should look like: USB drive > PS4 > UPDATE.
-
Download the correct update file from PlayStation's official website. Go to playstation.com/support and find the system software update page for your console.
There are TWO different files — a small update file and a large reinstallation file. If Safe Mode asks for a reinstallation, you need the larger file (usually around 1 GB).
-
Save the downloaded file into the UPDATE folder and make sure it is named correctly. PS4 files must be named PS4UPDATE.PUP and PS5 files must be named PS5UPDATE.PUP — all capital letters.
Do not rename the file extension. Do not put it in a subfolder inside UPDATE. It must be directly inside the UPDATE folder.
-
Insert the USB drive into your PlayStation, boot into Safe Mode, and select 'Update System Software' > 'Update from USB Storage Device.'
If the standard update option fails, try option 7 — 'Reinstall System Software.' This requires the larger reinstallation file.
When to Call a Professional
If your PlayStation is stuck in a boot loop and you cannot get Safe Mode to accept any USB update file, the internal storage may be corrupted or failing. A repair shop can replace the hard drive and reinstall the system software for around $80 to $150. You can also try replacing the hard drive yourself with a guide from PlayStation's website.
Frequently Asked Questions
What is the difference between the update file and the reinstallation file?
The update file is small (around 500 MB) and patches your existing system software. The reinstallation file is large (around 1 GB) and completely reinstalls the operating system from scratch. If your console cannot boot, you almost always need the full reinstallation file.
Will reinstalling the system software delete my games and saves?
Yes. A full system software reinstallation erases everything on the hard drive. This includes games, saves, screenshots, and settings. If possible, back up your data before reinstalling. If the console will not boot, the data may already be inaccessible.
Why does the USB drive have to be FAT32 or exFAT?
PlayStation's Safe Mode can only read FAT32 and exFAT file systems. Windows computers often format USB drives as NTFS by default, which PlayStation cannot read. Reformatting the drive erases everything on it, so save any important files first.
