The signature failure of save re-signing: you do everything “right,” and the game still announces the save belongs to another user. The cause is a mismatch between the account the save was signed to and the account you’re playing on.
How Apollo Decides the Account
Apollo auto-detects the current profile’s IDs — PS4 User ID and Account ID; PS3 PSID, IDPS and Account ID. Re-signing stamps the save with whatever Apollo detected at that moment. Almost every mismatch traces back to the detection context:
- Wrong profile signed in: you re-signed while logged into a different local profile than the one you play on. Sign into the target profile and re-sign again.
- Save was never actually re-signed: copying a decrypted save into place is not re-signing. Run the save through Apollo’s import/re-sign function so
param.sfoand the encryption are actually rewritten for your account. - Downloaded saves: saves from the Online Database are encrypted to the contributor — re-signing is mandatory, not optional.
The PS3 owners.xml Override
On PS3, if auto-detection picks wrong IDs in multi-account setups, you can override them: place an owners.xml file at /dev_hdd0/game/NP0APOLLO/USRDIR/owners.xml with the correct account data, and Apollo will use those values for re-signing instead of the detected ones.
PS4 Notes
- Encrypted saves on USB live under
PS4/SAVEDATA/<account-id>/— if the folder name doesn’t match your account ID, the console won’t associate the save with you. Let Apollo write the folder structure rather than hand-renaming directories. - Offline-activated (fake) Account IDs — which Apollo’s account tools can create — must be consistent between the resign step and the play profile.
Verify the Fix
After re-signing under the correct profile, load the game with that profile. If the message persists on a save that previously worked, restore the pre-edit backup and re-do the edit following the step order in PS4 re-signing or PS3 re-signing.
