CE-100002-3CE-100002-3 indicates that an application update did not install correctly. It does not itself identify a system software fault or a damaged drive. Recording what was updating and where it failed avoids deleting a game when the problem is still at the download stage.

Find your situation
See all the clues. Choose the one that matches what you observe.
Download never completes
Separate transfer from installation before deleting the game.
One app: complete download, failed installation
An isolated failure allows a repair limited to that title.
Several apps, or system software too
One local game installation no longer explains the whole pattern.
Returned after reinstalling
Keep the result and stop repeating deletions.
Diagnostic signals
- ObservationPercentage alone is not a diagnosis
- Record Download or Install, title, version and the full code. A different code changes the diagnostic path.
Step-by-step solutions
Identify stage and scope
Identify what failed without deleting data.
Open Downloads/Uploads and note the failed operation without cancelling an active installation. Check whether other recent updates finished; do not download large games just for a test.
If downloading is incomplete, follow the download branch. If it finished and one title fails to install, follow the app repair. If system software also fails, address its specific error first.
When downloading does not finish
Check the download details and PlayStation status. During a confirmed interruption, wait; reinstalling cannot repair a transfer that cannot complete.
If a space warning appears, review Settings > Storage and manage it using Sony’s guidance, protecting what you need. CE-100002-3 alone does not establish insufficient space. After resolving the download condition, use the available retry; this is different from deleting the installed app.
One title fails to install its update
Save your game, finish active operations and restart PS5 normally once. Do not cut power. This checks whether the failure persists in a fresh session.
If system software is pending, update it through Settings > System > System Software > System Software Update and Settings. Then check the title’s update through its options. If it works, stop; if only that title fails again, consider the limited reinstall below.
If it returns after reinstalling
Do not repeat the same deletion. Give PlayStation the title, system version, storage, exact stage and reinstall result. If the code changes, provide both codes in order.
Recurrence no longer supports a repair based only on replacing that installation. Wait for a specific support-directed test before changing storage or system software.
Advanced checks
Continue if the earlier steps did not help. Read each procedure’s precautions first.
Reinstall only the isolated title
Only if one app still fails after restart and the system check: confirm library or disc access and time to download it again. Verify a recoverable copy of important saves through Sony’s method for PS4 or PS5; do not assume all saves support individual USB copying.
Select that app on Home > Options > Delete. Reinstall and update it once. Do not select Saved Data or Reset PS5. If it works, stop; if the error returns, follow the recurrence branch.
Still not working?
Stop if the error returns without new information. Give Sony the stage, titles, storage and completed tests; do not extend this procedure automatically into system software reinstallation.
