What is Bootloader Unlock?

Bootloader unlock is a gateway for Android device users towards its unlimited possibilities of customizations and other features. By unlocking the bootloader, you can root your device (jailbreak), flash custom firmware, kernels, recovery and install third-party modules and apps, etc.

A Bootloader is usually locked on an Android device due to system security or privacy-related measures. As the Android OS is an open-source platform and anyone can do anything with it, the smartphone OEMs always want to stick to their skin and OS version specially developed and designed for their own device models. That’s why most of the OEMs don’t provide an unlocked bootloader out-of-the-box.
