I'm a
Hen fw 9.00 user with no backport, maybe it's different on the other hen fw and backport file user.
I will give you the steps in outline only.
1. Select which HFW save you want to overwrite. Remember which saves, how long duration (eg autosave1, duration 7 minutes).
2. From the Apollo save tool select that save and then export decrypted.
3. Insert flashdrive containing the checkpoint.dat file.
4. Open ps4 xplorer application > mnt > usb0 > the folder containing the checkpoint.dat file > select copy on the file (checkpoint.dat file only, no need other file/folder).
5. Go back to the data folder > apolo > ID > find the cusa24705 autosave1 folder > paste and overwrite the checkpoint.dat file.
6. Close ps4 xplorer and open apolo save tool again.
7. Select HFW save, make sure autosave1 and the duration is 7 minutes, select import decrypted. A success message will appear.
8. Close Apollo the right way using back button.
9. Open HFW and load save with a duration of 7 minutes.
10. Do a manual save. Done
There is no need to do resign at Apollo, even for
@cyber1000 release CUSA28561 users, because CyB1K release saving data with ID CUSA24705, I don't know why. There may be a glitch when the HFW file is hacked.
If users of the CyB1K release do resign in the Apollo Save Tool, the save data will not be read.
