Root K20 Pro / Mi 9T Pro with Patched Boot Image (Magisk) [MIUI 12]

From this post, you will be able to download the Magisk patched boot image for Xiaomi Redmi K20 Pro / Mi 9T Pro. If you are stuck on TWRP while flashing a Magisk ZIP package on K20 Pro, getting errors like “unable to mount /system/,” this article is a perfect alternative solution for you.

I often faced errors while flashing a Magisk ZIP package on my Redmi K20 Pro in TWRP recovery. So, what I do is rooting via fastboot, which works perfectly without any issues. So, basically, if you want to get root access using Magisk by patching the boot.img file, you can directly get that from the link given below. I patched the MIUI 12 boot.img file for the Xiaomi Redmi K20 Pro / Mi 9T Pro users. You can download it on your computer and flash using fastboot commands. A detailed tutorial is also given below if you don’t know how to root using fastboot commands.

Download Magisk Patched IMG for Redmi K20 Pro / Mi 9T Pro

Download the magisk_patched.img file for K20 Pro / Mi 9T Pro on your computer from the link below. But keep in mind, this patch is created from the latest MIUI 12 ROM. It’s working correctly on MIUI 12 and is not tested on older builds. If you have MIUI 12 on your Mi 9T Pro, you can proceed ahead! We are not sure about the older builds, so be careful.

After downloading, check out the pre-requisites and then the tutorial carefully to root your Redmi K20 Pro / Mi 9T Pro using fastboot.

NOTE

If you have a newer version of MIUI 12 or even a different ROM, the above-linked file may not work on your phone, and it may cause bootloop. In that case, you need to extract the fresh boot.img file from your current ROM ZIP package. Get the one and come back to this tutorial!

If you don’t know how to get the stock boot.img file, you may follow our detailed guide here:

Pre-requisites

  1. Your Xiaomi Mi 9T Pro / K20 Pro must have an Unlocked Bootloader!
  2. Download the latest version of the Magisk Manager on your phone!
  3. Install MIUI 12 if you are still on the older builds.
  4. Set up ADB Drivers on your computer. (Windows / Mac)
  5. Make sure your phone has at least 80 – 85% charge. If not, please do charge it before starting the experiment.
  6. You need to enable the USB Debugging mode to connect your Android phone to the computer. (Settings > About Phone > Build number > Tap it 7 times to become developer; Settings > Developer Options > USB Debugging).

Backup Mi 9T Pro (Warning)

Before starting the tutorial, we suggest you to backup your essential documents from the device and make a copy of it to your computer. On performing our experiment, your device may get wiped, and you may lose everything from the phone. We don’t want that. In that case, we have a list of applications that may help you in creating backups within the phone. Later on, you can copy the files to the computer for a safer side.

Once you are sure that you are done with the backup stuff, please proceed to the tutorial below on How to Root Xiaomi Mi 9T Pro quickly.
