Xiaomi, a Chinese based Smartphone manufacturer is a well-known brand for all the Android lovers.

Coming back to the actual story, Xiaomi has locked the bootloaders on the latest releases Xiaomi Redmi Note 3, Xiaomi Mi 4c and Xiaomi Mi Note Pro smartphones.

With the locked bootloader, users are unable to flash the device with custom ROM’s. Redmi Note 3 shipped with a locked bootloader and the other two devices Mi 4c and Mi Note Pro got the locked bootloader after a firmware update. The reason behind the locked bootloaders is that, Xiaomi wants to restrict the installation of any malware into the device by the third-party retailers before it reaches the end user.

So, now all the users of these devices need to follow specific procedure for unlocking the bootloader. As of now, the below guide will work for the MIUI China developer version (6.1.12 or later).
