Explanation
What this error means
CE-100002-3 is documented as “failed to update the application.” A game’s patch couldn’t be applied. This is a download-and-install problem — an interrupted or corrupted patch, limited storage, or a stuck queue — not a sign the game or console is broken.

Diagnosis

|---|---|---|
| Patch download corrupted or interrupted | Very likely | Yes — re-download the update |

Repair
How to fix it
Ordered easiest-first. Try the next step only if the error comes back.
-
Retry the update
Highlight the game > Options > Check for Update, and let the patch download again. A second attempt clears most transient failures.
-
Free up space first
Patches need working room. Settings > Storage — clear a few GB if the SSD is close to full, then retry.
-
Restart the console
Power > Restart PS5 resets the download manager before you try the update again.
-
Delete the patch data and re-download
If a half-applied patch is the problem, deleting and reinstalling the game pulls a clean, fully-patched copy. Saves are kept.
-
Rebuild the database
Safe Mode > Rebuild Database clears a corrupted update index without affecting games or saves.
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 update fails for many players on launch day when servers are busy.
- status.playstation.com shows store or content-delivery issues.
- A wired connection with healthy internet still fails — likely a server-side package issue.
Questions
FAQ
Why does updating fail repeatedly?
Usually a corrupted patch download or tight storage. Re-downloading after freeing space, or reinstalling for a clean fully-patched copy, resolves most cases.
Is reinstalling overkill?
It’s the reliable fallback when a patch keeps failing — you get a clean, current copy, and saves are preserved separately.
Could my connection be the issue?
Yes. Patches verify against a checksum, so a flaky link corrupts them. A wired connection is the most reliable way to apply large updates.
