How to root Android using Magisk

Magisk is a great alternative for SuperSU and in some ways better than it. Here are a few features of it:

Features

• 100% fully open source and easy to build!
• Magic Mount: 
  Allow you to do any system (vendor) modification without actually tampering the partitions.
• MagiskSU: Open Source Root Solution
  Root your device with MagiskSU, based on phh's Superuser, which is based on CM Superuser.
• Magisk Manager: 
  MagiskSU Root Management, Install / Upgrade Magisk in-app,
  Manage, Upgrade, Download, Install Magisk Modules within a few taps.
• Magisk Hide: 
  Hide Magisk from detection, including SafetyNet, which is used in Android Pay, Pokemon GO etc.
• Resetprop: 
  Allow you to do any modifications to system props (build.prop), including read-only props.
• Multiple Entry Points: 
  Provide several entry points to developers, reliably pausing the boot process before everything is done.
  Include post-fs (cache) mode, which happens even earlier than data is mounted (used to replace Boot Animation etc.)
• Standard Stuffs: 
  Remove dm-verity, forceencrypt; includes a super complete busybox to guarantee consistent behaviour, and can also be toggled to be used universally.

Let's begin with our guide already. So first of all, you'll need to have a custom recovery installed. I recommend installing TWRP for your device.

Step 1:

Download the Magisk Zip from here and place it in your SD card or your device.

Step 2:

Now boot into Recovery Mode and swipe to allow modifications. Then you'll see a screen like below. 

Step 3:

Click on Install and browse for your Magisk Zip in your device that you downloaded earlier. Then click on it and swipe to flash and wait.

Step 4: 

After you're done flashing, reboot your device from the bottom-right option. After your reboot is complete, your Magisk should be completely installed. Download Magisk Manager from Playstore and install it. That's it.
