Hi am first writingHello, I've been using Xiaomi phones for 3 years already, my first phone was mi5s 128gb, I served faithfully and faithfully, and it got old, I bought a new phone ... mi9se, but I ran into a problem, I have a locked bootloader on this phone, how do i need to unblock it so that i can use nfs and all xiaomi buns (when you go to si mi5s account color, and mi9se is black faded color)
