Some questions
If I format data do I become decrypted? Or no overity is needed? What encryption exactly format data remove?

If I am decrypted the only way to go again encrypted is to flash stock oxygen os? Not just format data? Why?

I was decrypted on oxygen os, but I then I formated data and flashed a custom recovery. Now whenever I boot I to recovery it sends me on a pin pattern in mount decrypt settings. Why is this happening?
