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.
