Getting root rights to Xiaomi Redmi 9 is a process that opens up hidden Android features but risks turning a smartphone into a brick. This model, launched in 2020 with the MediaTek Helio G80 processor, has its own features of unlocking the bootloader and installing a superuser. Unlike devices on Qualcomm Snapdragon, universal tools like Magisk will not work here without pre-preparedness.
In this article, we will discuss three current methods of obtaining root rights (through official unlocking, patching boot images and alternative firmware), compare them in complexity and security, and discuss in detail the typical errors. We will focus on bypassing the Mi Account lock after a reset, a problem that affects 30% of users when unblocking correctly. If you are a beginner, start with the Preparation section, which lists all the necessary tools and conditions.

β οΈ Attention: Redmi 9 with firmware MIUI 13+ If the phone is stuck on the logo after firmware, you need to roll back to an older version via Fastboot.
Method 2: Install custom recovery (TWRP) without official unlocking
This is a good way to do this if the Mi Unlock Tool refuses to unlock the bootloader (for example, due to regional restrictions).We will exploit a vulnerability in MediaTek that allows you to temporarily access the firmware.
