WHAT IS BOOTLOADER AND WHY IT IS IMPORTANT?

FIRST THING, WHAT IS BOOTLOADER?

? In short, A bootloader is a software that runs every time your phone starts up. It tells the phone what programs to load in order to make your phone run

? When you turn on the phone, bootloader do the important job which is starting up the OS.

? And this is the reason why phone keeps their bootloaders stored in stable memory.

?Bootloader has more important functions, Bootloader can start up Recovery Mode, it can execute large pieces of code that totally rewrite the Android Operating System

? The bootloader is important because it loads both of these pieces of software. With a working Bootloader your phone is nothing but just a useless brick

SORRY!! But Yes, a brick but with some buttons

? A locked bootloader means you can't install your own Operating System. It means if you want to install a latest version of any custom ROM with lock bootloader it is impossible!! Sorry but this is the TRUTH!!

? Locking the bootloader is very serious practice with some serious implications. It might be disliked by Android Developers and Enthusiasts who wish to install Custom ROMs or something to change the phone.

WHY BOOTLOADERS ARE IMPORTANT?

? Some Bootloaders, however, contain an extra layer of security that make sure that it only loads Operating System which has its approval.

? The Exact process of checking for unauthorized software varies from phone to phone, but effects are gonna be the same. You can't run any Operating System the manufacture didn't approve.
