How To Unlock Bootloader On Your Android Device

Bootloader is a code which is executed before any operating system starts to run. This is executed before any software on a device. It finds the memory partition where OS is located and tries to boot the OS.

Most android device manufacturers have their own modded versions of Android. For example Xiaomi uses MIUI, Huawei uses EMUI as their custom OS built on top of Android OS.

Every device also comes with its own in-built bootloader fabricated by device manufacturer. These bootloader programs are generally locked in order to prevent installation of any other firmware into the device.

In simple words, Bootloader programs prevent you from changing your in-built OS to another modded OS of your choice. Unlocking bootloader allows you to install custom Firmware on your Android phone, root and install mods.

You may ask “Why do I need to flash custom ROMs?”. Actually, Custom ROMs get earlier updates, can improve battery life and may save your RAM by running less junk apps in background.
