What is Bootloader and why is it locked on OnePlus 8/Pro?

If you are a new user on this website or a new Android user then you might not know what bootloader unlock is and why do you need to unlock the same.

To start off with this one you need to understand the booting process on an Android phone. Typically, the startup process of a device is called as boot-up. During this boot-up process, the device is unusable by the user until it boots-up completely.

A boot-loader is a piece of software that loads other software(s) during the boot-up process. In Android, this bootloader is locked to make sure no-one can alter what is being loaded by this bootloader.

So, in simple words the bootloader software is not something that is meant for the user but meant to run the device securely. If not secured, some hacker may alter the boot-up process leaving the device unusable.

Locking the bootloader ensures that the software integrity of the phone is trusted, meaning it has not been modified from the stock and hence used to provide or discard warranty, etc.
