mi unlock status ?

[Endercraft]

Hey,
I've been trying to root my old phone (Redmi Note 4) but when I need to unlock my mi account (the mi unlock status in developer options), I'm totally lost. Some MIUI websites straigt up don't work anymore and I haven't found a clear procedure on how to do so. I see that you have to wait 168 hours for something..
Can anyone show me a guide to follow to do this that's clear ?
Thanks.
