Turn off Fortnite f2a without code?

I have activated the f2a at fortnite and after a few months I reset my phone so that I can play it smoothly again. But then I had to enter this f2a code but was on the old memory: /. And now I'm not in Fortnite purely, can someone please tell me how I can turn off this code without having to enter it first.

For this you have to reboot your mobile device. Once you have done this, it should work without f2a code. If this is not the case I would format the device.

Reboot?

To do this, press in the system settings and under Formatting on the button function.
