What is bootloader & what actually it is?

So, a bootloader is basically the code that is executed before booting up the Operating System. This basic concept is true for any OS on any device and platform. Since this guide is for an Android device, we’ll specifically talk about it. Each Android device has a bootloader that tells the OS kernel to boot. But since Android is an open-source operating system, and many manufacturers have their own variant of it, the bootloader is different too. That means each manufacturer have their own version of bootloader that is unique to the model and the hardware inside it.
