Step-by-step solutions
Restart PS5 normally
Save progress before ending your game session.
Finish active operations and use Restart PS5 from the power options. Do not cut power.
After restarting, check for pending system software before trying the app update again.
Update the system and retry the app
Do not interrupt an installation in progress.
Apply the system software update from Settings following the PS5 prompts.
Retry the title’s update. If CE-100002-3 returns, note the app and failure timing before reinstalling.
Advanced checks
Continue if the earlier steps did not help. Read each procedure’s precautions first.
Reinstall only the affected app
Confirm you can recover it before deleting it.
Check library access or installation media and protect important saves.
Delete only the app through its options, reinstall it and retry the update. Do not select Saved Data or a PS5 reset.
Still not working?
If reinstalling does not resolve the code, give PlayStation the title, system version and each attempt’s result. Avoid repeating deletion without a change in diagnosis.
