What is Bootloader on Android?

A Bootloader is a system code that runs on a device when you turn on the device especially on each and every electronic device that runs on an operating system like phone, computer, etc. Before loading the operating system, the bootloader decides whether to boot the device into the system or stock recovery mode. Due to the security purposes, all manufacturers launch their devices with a locked bootloader to stick on the stock ROM and stock recovery.

But in order to install any third-party file on your Android device, you will need to unlock the bootloader at first and yes it’s mandatory.
