Unlock Bootloader: Overview

The bootloader program is responsible for starting the correct operating system on a device when it’s powered on. It packages the instructions to boot the OS from the kernel. This applies to devices such as smartphones, tablets, and PCs.

Having a Locked or Unlocked Bootloader determines whether you can easily root a device. If you root your device, you’ll have superuser or administrator access to the operating system running on your phone. This means you can make changes to some system settings, manage customizations, make tweaks, and more.

However, unlocking your Android Device Bootloader may pose security risks. Although Android users often unlock their device bootloaders to root and install Custom ROMs, it may void your device warranty and cause problems such as boot loops and bricking. Therefore, smartphone OEMs do not unlock the bootloader or root your device by default. It’s ultimately up to you to decide whether or not to unlock your device bootloader based on your needs and preferences.
