(Vivek) Guide] Root Mi Phone with SuperSU without flashing TWRP Recovery.100% working method.

vivek Hello Mi fans,
           If you have been using Android for a few years, you might have heard a term rooting or root permission. Sounds familiar? Today I'm going to teach you all how to root your Mi Phones with SuperSU via TWRP Recovery by not losing your stock recovery. But first, let me tell you all what Rooting is.

What is Rooting?
If you’re unfamiliar with the term, rooting simply refers to the act of obtaining access to commands, system files, and folder locations that are usually locked off for the user. Rooting could be thought of as moving from being a system user to becoming an administrator, with the additional freedom and risks that come from more control over the deeper workings of your device.

Once rooted, users can install and run applications that require special privileges, bypass carrier installed software, and even remove bloat-ware applications added by manufacturers and carriers. Root access is even needed if you want to install trivial things like certain custom fonts and can unlock new features in certain apps and launchers.
The actual method required to root your phone will vary from model to model, so we can’t possibly cover them all. Unfortunately, these can also be patched out by manufacturers and even upgrading your software can cause root exploits and permissions to be lost.
I hope you all have understood what Rooting is. Now, let's start with the procedure to Root your phone.

Pre-requisites:
1. PC or Laptop
2. Unlocked Bootloader
3. Minimal ADB and Fastboot
4. SuperSU

Note:
First boot always take time so have patience.
After flashing any ROM let your phone cool down to normal temperature before you start using it. Please don't complain the phone is heating and lagging. Flashing anything have heavy CPU usage, thus result in heating.
Disclaimer:If anything goes wrong while flashing, don't blame me. It's a risk that you choose to do so whatever happens you are responsible for it and not us.
