2. Install Magisk Manager and Patching boot image

• Extract boot.img from the official ROM zip you downloaded and transfer it to the phone.
• Open Magisk Manager
• Tap “Install” in Magisk Manager

• Magisk Manager will patch the image, and store it in [Internal Storage]/Download/magisk_patched.img
• The output magisk_patched.img file should be now transferred to your computer. Most appropriately, to the Mi Unlock folder where fastboot.exe is located.
• Reboot your phone to fastboot recovery mode. Open a command prompt in the folder of the Mi Unlock tool and input:

fastboot flash boot magisk_patched.img

This will flash the patched Magisk-enabled bootloader to your phone.

• Reboot the phone and it’s almost done! Verify root status in the Magisk Manager app.

Let the device reboot. The device may force reboot several times, and it’s nothing serious. After completing the initial procedures, install the latest Magisk Manager. The phone will reboot eventually. Once again launch the Magisk Manager, select the “Beta Channel” for updates and enable Magisk Hide. Then all you’ve to do is to reload the Magisk Manager, and check for Safety Net: you should have the green light!
