How to unlock Xiaomi Mi 6 Pro: official and alternative ways

Xiaomi Mi 6 Pro is the flagship smartphone of 2017, which is still popular among customization enthusiasts. However, factory lock bootloader limits the ability of users: it is impossible to install custom software, get root rights or even bring the device back to life after a software failure. Unlocking is a must for deep customization, but the process is fraught with risks and nuances, especially for outdated models like the Mi 6 Pro.

In this article, you will find the most current ways to unlock the Xiaomi Mi 6 Pro in 2026, including the official method through the Mi Unlock Tool, workarounds for devices with a tied Mi Account, and solutions for cases where standard instructions do not work.

Why should Xiaomi Mi 6 Pro be unlocked?

Factory bootloader locking on Xiaomi devices is introduced to protect against unauthorized access and malware installation. However, for power users, this becomes an obstacle. Here are the main reasons why Mi 6 Pro owners decide to unlock:

Without the unlocked bootloader, all these manipulations are impossible. However, remember: on the Xiaomi Mi 6 Pro with the unlocked bootloader, the Find Device function stops working, and there may be problems with data encryption and banking applications.
