What is Bootloader? Pros & Cons of Unlocking Bootloader

Bootloader:

You may have heard this term quite often. In simple terms, a bootloader is a command which needs to be executed before any Operating System (OS) is booting up. Most of the devices which run on a particular OS have some short of bootloader included. Such as in your PC, your laptop, mobile phones, and any other such devices. The bootloader’s simply packed the instructions to boot an operating system kernel.

A bootloader is extremely processor specific as it’s the first thing that starts up in your device before any software. In the PC world, you can simply understand a bootloader as a Bios, through which you can choose the boot device, Change your stuff and also tinker with the CPUs and GPUs. While in this article we are discussing the Smartphone Bootloader’s or to be more specific Android Smartphone bootloaders. Why are they locked by default? What can you do after unlocking them? What are its pros and cons ?? And many more things.

Bootloader in Android Smartphones

Android devices come with different types of bootloaders for their different devices. As Android is an Open Source you can see it in various forms in various devices running on any SoC available. As I earlier told you, bootloaders are processor-specific and every OEM has its own version of bootloader specific for the hardware present in its environment.

Why OEM’S Lock their bootloaders? 🔒📱

As we all know Android is an Open Source and due to this, you can modify it in every way possible. As we all can see through the two devices running in the same Android version may not have a lot of things in common in terms of UI and sets of features. OEM spend a lot of R&D and efforts to make their devices to Stand out than the crowd in every possible way.

So they do the same with the software. They don’t want you to tinker with the software of your device and what it to use in the way it was intended to. With a locked bootloader, it’s impossible to flash any custom recovery and custom ROMs and even the official fastboot ROMs.

So locking a bootloader is a kind of sense of security for both the OEMs and the devices itself.
