Root on Android is one of the most sought after features by users. After having root, one of the biggest impediments to be able to modify our software, is the bootloader. In this way, each brand blocks the smartphone in a different way and therefore each has a way to unlock it. So, today we bring you a complete tutorial in which we will teach you how to unlock bootloader on an Android mobile of any brand.
For those who do not know it, the bootloader is an internal program in charge of loading the operating system at startup completely. Being blocked, this does not allow us to install anything that is not official software. So, today we will learn how to unlock the so-called boot loader.

Because each brand includes a different configuration to its smartphones, we will have a method for each one. In some cases we can do it through an application, in others with commands and the program ADB , but today, the marks leave us “more or less” easy to unlock your bootloader.
