How to unlock Xiaomi Mi Max 2: The Complete Guide

Xiaomi Mi Max 2 remains a popular device due to its huge screen and autonomy, but owners often face restrictions imposed by the manufacturer. The most common problem is a locked bootloader (Bootloader), which does not allow you to install custom firmware, obtain Root rights or fully modify the system. The process of removing these restrictions requires care and preparation, as an error can lead to the inoperability of the gadget.

In this guide, we will discuss how to unlock the bootloader officially through the company’s servers, and the nuances of resetting the binding to the account.
