Effortless Way to Flash TWRP and Root Mi 9 (Codename Cepheus) 1

Some users of Xiaomi Mi 9 become hesitant to unleash its true potential. Some others simply can’t wait for their devices to arrive and immediately unleash the best beneath the awesome Mi 9 body.

The key stage to a success of Mi 9 beast unleashing is a custom recovery. Replacing the stock MIUI Recovery with a custom one allows users to flash almost anything including custom ROMs, Magisk root, tweaks, and mods.

Therefore, you will need a custom recovery to bring your Mi 9 device to a higher level of a flagship phone.

This article will guide you through the steps necessary to flash TWRP recovery and to root Xiaomi Mi 9 (codename Cepheus).

We will use a TWRP installer toolkit. This is to simplify the process of flashing TWRP.

Traditionally, you will need to type some geeky commands which are not fairly easy to remember. This tool requires you to press 1, 2, or Enter keys on your keyboard. No complicated things to remember. Simply follow the on-screen instruction and you are practically done.

Despite this method is easier, we strictly encourage you to create backup of all your crucial data and files. This method needs unlocked bootloader. Its process makes you factory reset your phone and hence you’ll lose your files.


  1. You will need a Windows computer either a PC or a Laptop. Windows 8/8.1/10 64-bit is recommended.
  2. A Type-C USB data cable. Make sure it’s a data cable and not a charging-only cable.
  3. Download ADB Fastboot Driver (zip).
  4. Download TWRP installer toolkit (zip).
  5. Download latest version of Magisk root (zip).
  6. Download Disable Force Encryption (zip).
