What Is a Bootloader

A bootloader is an integral part of a device known as a bootstrap loader or boot program. It is a specially designed operating system software that loads to a computer or smartphone system.
The program is launched by a CD/DVD, hard disk, and smartphones installed in the internal storage.

Why Is a Bootloader Locked

The manufacturers lock the bootloader for specific reasons, and those are:

  1. Prevent unauthorized installation of a new ROM.
  2. Keep the device safe from hacking or cracking.
  3. A locked bootloader doesn’t let you install any custom recovery.
  4. OEM’s lock bootloader so that customers can use their optimized operating system.
