Hacking Deleting Local PS4 Trophy Data?

[Kururin]

Hello,
I have some fpkg game installed and removed it, and now I would like to remove their trophy data too. Since the stuff isn't synced online how would I go about deleting these trophy data which the game have been removed? I tried ftping and deleting some trophy.trp but it doesn't really remove the entry..
Thanks

Did some digging into PS4 filesystem and figured this out along with how to delete those annoying notifications piled up and error log that's piled up in particular system > error history. For local trophy deletion that's isn't synced to $ony servers, it's the same as PS Vita as you have to modify trophy_local.db.

To delete PS4 notifications:
FTP into ur PS4 and delete the /system_data/priv/mms/notifications.db

To delete the error history that gets saved into System > Error History:
FTP into ur PS4 and delete all the .json files inside /system_data/priv/error/history/ folder

EDIT: Well I played around but I am seem to never allowed to change the ID of the trophy (not the trophy_id but the index - the list number of the trophy in the db)(gives me a error - foreign key violation) and it just fills up the space later with null values. So I partially gave up and not doing the rebuild as I have far too invested to do that although I have app.db backed up.. If anyone can shed light on this go ahead.
