Unlock Bootloader On Xiaomi Smartphone

What is a Bootloader?

In layman’s terms, a bootloader is software that runs before the phone starts. The liaison between the phone and the hardware tells the phone which programs to load. Hence, the bootloader starts the Android operating system when you press the power button on your phone. Due to the security of the bootloader, many manufacturers lock it so that no one breaches it.

Bootloaders also help start the recovery mode, fast boot mode, etc. Recovery mode is the code in the Android smartphone that can rewrite the Android operating system. To a certain extent, the bootloader is an essential part of the Android smartphone, which helps load both software simultaneously. If the bootloader doesn’t execute the set of programs, then the phone becomes useless.

Why Unlock the Bootloader?

Bootloaders are locked to keep the phone’s security intact, and no other operating system can be loaded apart from the one the manufacturer has shipped. When the bootloader is unlocked, the user can install a custom recovery such as TWRP (widely used) that lets users flash custom ROMs, mods, patches, kernels, etc.

Once you unlock the bootloader on your Xiaomi smartphone, you can install an operating system of your choice, such as LineageOS, Pixel Experience, Resurrection Remix, etc., that provides efficient performance and stability over Xiaomi’s stock MIUI operating system.
