Now that you have fixed the problem, avoid it happening again:

  1. Never mix region updates. If you have a USA console, only install USA updates.
  2. Use "Install and Delete" in FBI. Deleting the CIA after install prevents you from trying to re-install the same file twice by accident.
  3. Do not use Nintendo's "Repair Software" tool on modded consoles. It breaks ticket databases.
  4. Back up your NAND via GodMode9 monthly. If your database corrupts, you can restore a known-good state.
