Literally all I want to know is how to remove phone from my flyme account. I gave the phone to my father and its unusable. He cant even install anything AFTER factory reset, because he cant create new accoutn while the old one is still linked.

So, HOW, do i unlink flyme account from a phone? I tried to follow some post i found on facebook but it is probably outdated. I tried to translate the user managment page: https://i.flyme.cn/uc/webjsp/member/detail

But nowhere does it even mention something like deleting the accoutn or unlinking the phone.
