- Using FTPiiU Everywhere, navigate to the following location: /storage_slc/rights/ticket/apps
- Here, you will see a list of "000x" folders, with the information from the keys.txt file, the duplicate files are located at "(000x/000000xx.tik@)" navigate to "000x" folder, locate the file "000000xx.tik" and delete.
- Make sure your booted into CFW or else you will not be able to see contents of the "/storage_slc" folder, once the file has been deleted, shutdown your console and wait a few moments before turning it back, funny as it may sounds, sometimes, just rebooting your console will not complete the file delete process, it's best to do a full SHUTDOWN.
So every time a game gets installed, the ticket is stored in the "/storage_slc/rights/ticket/apps" location, so when a game of the same Title ID is installed, the ticket gets merged with the existing ticket, so when your looking at the file size of the ticket, you will notice it is larger than the other tickets that is installed.
FYI:
I have noticed on some occasions with VC injects, when you delete a game from the console using Data Management, sometimes the ticket doesn't get deleted from the system for some odd reason, so the only way to find out if it has is to run the tik2sd app and check the keys.txt file.
