Explanation
What this error means
SU-41350-3 means “the update file cannot be recognized.” It shows up when updating from USB in Safe Mode and the console can’t read the file you provided — typically the wrong file, an incomplete download, or a USB drive that isn’t formatted or named exactly as the PS4 expects.

| Cause | How likely | Fixable at home? |
|---|---|---|
| Wrong file, or reinstall vs update file mismatch | Very likely | Yes — download the right one |
| USB not FAT32/exFAT or wrong folder path | Likely | Yes — reformat and re-copy |
| Incomplete or corrupted download | Possible | Yes — re-download |
| USB drive not detected by the port | Possible | Yes — try another drive/port |
Repair
How to fix it
Ordered easiest-first. Try the next step only if the error comes back.
-
Use the right file for what you’re doing
Reinstalling in Safe Mode (option 7) needs the larger reinstallation file; a normal Safe Mode update (option 3) needs the smaller update file. Mixing them up triggers this error.
-
Format the USB correctly
Format as FAT32 (or exFAT for the large reinstall file), then create PS4/UPDATE and save the file as PS4UPDATE.PUP — the path must be exactly PS4/UPDATE/PS4UPDATE.PUP.
-
Re-download from playstation.com
Grab a fresh copy of the correct official file and let it download completely before copying it across.
-
Let the copy finish, then eject safely
A half-written .PUP is the usual cause — wait for the copy to complete fully before removing the stick.
-
Try a different USB drive or port
Some drives aren’t reliably detected. A small, plainly formatted stick in a rear USB port is the safest bet.
Escalation
When it's not your fault
Signs the problem is on Sony's side — or in the hardware — rather than anything you can change:
- The official download was briefly incomplete because the server was mid-update.
- The same correctly-named file fails on one USB stick but works on another — a flaky drive.
- A region-mismatched file from the wrong PlayStation site won’t be recognised.
Questions
FAQ
Reinstall file or update file — which do I need?
For a normal update use the smaller update file (Safe Mode option 3). Only use the larger reinstallation file (option 7) if you intend to wipe and reinstall — and back up saves first.
What’s the exact USB path?
PS4/UPDATE/PS4UPDATE.PUP. A PS4 folder, an UPDATE folder inside it, and the file named precisely PS4UPDATE.PUP.
Does this erase my data?
The update file doesn’t. The reinstallation file does — so if you’re using option 7, back up saves to USB or PS Plus cloud beforehand.
