How to Re-Sign PS4 Saves with Apollo Save Tool

ByAdmin

Re-signing is what makes a save file created on one account or console work on yours. Apollo Save Tool does the whole job on the PS4 itself — here is the workflow for the current v2.4.0 build.

Before You Start

  • Install Apollo on your jailbroken PS4.
  • Back up your own original save first. In Apollo, select your save and choose the export option to copy it to USB — never overwrite your only copy.
  • Understand the two save states: encrypted saves (the format games write, tied to an account) live in PS4/SAVEDATA/<account-id>/ on USB; decrypted saves (the editable form Apollo works with) live in PS4/APOLLO/.

Step 1: Get the Save onto Your PS4

Place the decrypted save in /PS4/APOLLO/ on a USB drive (create the folders if needed) and plug the drive into the PS4. Saves downloaded from Apollo’s built-in Online Database arrive ready for the same process — downloaded saves are locked to the contributor’s account and must be re-signed before any game will load them.

Step 2: Let Apollo Detect Your Account

Apollo automatically detects your User ID and Account ID from the current profile — there is nothing to type in. If you use several profiles, make sure you are signed into the profile the save should belong to.

Step 3: Re-Sign the Save

  1. Open Apollo and browse to the save in the USB saves list.
  2. Select it and choose the option to import / re-sign the save to your account. Apollo updates the save’s param.sfo account information and re-encrypts it for your profile.
  3. Apollo copies the finished save to your console’s save data area.

Step 4: Test in the Game

Launch the game and load the save. If the game reports the save belongs to another user, the re-sign didn’t take — work through account-ID mismatch fixes. If the game calls the save corrupted, restore your backup and see corrupted save after re-signing.

Good Practice

  • Keep decrypted and encrypted copies separate and labelled by game title ID.
  • Re-sign one save, test it, then batch the rest.
  • Apollo can also work in the other direction: decrypt and export your own saves to USB (/PS4/APOLLO/) for backup — see our save backup guide.
