It does work, I'm literally farming the Freiza Event. The update doesn't patch the hack simply only deletes it. Like I said earlier uninstalling and reinstalling will fix the issue. What you said is also rude, I can assure you I did read and I can read.
If you deleted and reinstalled the game and the mod doesn't appear in settings try restarting your phone (may or may not fix the issue)
So the process is go to cydia and remove the hack, this should also respring your device, you may need to uninstall Dokkan ( I did not need to do this). Finally just download the hack again, I personally used the deb file that I already had in my documents on iFile.
So to sum it up:
Cydia -> Installed -> Recent -> Find Dragonball -> Click on it and press remove -> Restart/Respring your iDevice -> Download hack again
