Unlocking Xiaomi bootloader without PC: all ways and pitfalls

Unlocking the bootloader on Xiaomi smartphones is a must for custom firmware installation, root rights or device recovery after software failures. Most guides on the network require a connection to a computer, but what if there is no PC at hand? Are there working methods to unlock without using a PC?

In this article, we will discuss all the current ways to unlock the Xiaomi, Redmi and POCO bootloader without a computer, from official (with restrictions) to alternative (with risks).
