Most recent Android devices now come with locked bootloaders, making it difficult for most of these devices to be properly rooted. Sony Mobile, HTC, Nexus, and some other devices have official means of unlocking their bootloader, but most recent devices do not.
If you have searched for an official method to unlock your phone's bootloader without achieving success, you can then try this method. But I advice you verify if there's actually no official means to unlock your bootloader first. If you want I can help you verify this, just ask in comments.
Before attempting to use this guide, I strongly recommend that you backup your phone's firmware first. It is wrong to attempt new stuffs on your device without backups, just in case something goes wrongly your device is bricked.
