    DISCLAMER:
    Unlocking the bootloader may void the warranty of your device and erase all user data. So, make sure that you are out of the warranty period or you are sure about what you are doing with your device.

    Also, make sure to backup all important data out of the phone.

    What is a Bootloader and why is it locked?

    In computing, the startup process of a device is called as boot-up. During this boot-up process, the device is unusable by the user till 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.

    Usually a user can install a software only after the boot process is complete and when the device is ready to use. So, basically the bootloader software is not something that is meant for the user but to run the device. If not secured, the user 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.
