The option to enter superkey will only be shown just one time when you press the start cheat button. If you accidentally enter a wrong key then clear the data of the loader and try again once you enter the key your device will be marked as supported and it will display that Execution mode is set to Apatch.

⚠️ do not panic if it says “Please root your device using APatch”, even though you have already, just press start and enter the superkey.
