How to Unlock Bootloader of Xiaomi devices?

The owners of the new Xiaomi devices faced an unpleasant problem when trying to install a custom firmware: the bootloader was locked. A reasonable question arises: why does Xiaomi, whose products are in great demand not only in those countries where they are delivered officially, impede the full use of their devices? It turns out the reason is related to ensuring security against theft. Thieves can flash the smartphone and get access to personal information stored on it. However, if the bootloader is locked, they won’t be able to do it, because each Xiaomi device is tied to a personal Mi Account.

How to check whether bootloader is locked?

To check if the bootloader of your Xiaomi device is locked, you need to boot your smartphone into Fastboot mode, and then type the following command:

fastboot oem device-info

The result can be seen on the screen in the second line of the response message. Two options are possible:

  1. Device unlocked: true
  2. Device unlocked: false

It is clear that locking the bootloader imposes some restrictions on user actions. For example, Root access will become unavailable, even if it was gained earlier. To make things go back to the way they were, you need to unlock the bootloader. Below we describe in detail how to do it.
