Unlock Bootloader: Overview

The bootloader is a program that starts whenever a device is powered on to activate the right operating system. It packages the instructions to boot the OS from the kernel. Like a smartphone, tablet, or PC, etc.

A Locked or Unlocked Bootloader is what gives you access to root a device easily. If you root your device, it means you have a superuser or administrator access to the operating system that runs on your phone. Therefore, you can change some of the system settings, manage customizations, tweaks, etc.

Unlocking your Android Device Bootloader may get security issues. Android users often unlock their device bootloaders to root and install Custom ROMs. But it may void your device warranty sometimes. If your device bricked or stuck into boot loops, etc. For the same reason, Android doesn’t come rooted; smartphone OEMs also don’t want to unlock the bootloader or root your device.
