Obtaining super-user rights to the Xiaomi Mi 9T Pro is a logical step for those who want to unleash the full potential of their device. The standard MIUI shell, while functional, often limits the ability to deep customize the system, remove pre-installed debris and fine-tune energy saving, a process that is not without risks, but with the right approach allows you to turn the smartphone into a powerful tool under the full control of the owner.
Owners of the Redmi K20 Pro (global version known as the Mi 9T Pro) often face the need to bypass system restrictions to install specialized modules or data backup at a low level. Root access gives privileges that are usually closed by the manufacturer for security reasons. However, before starting any manipulations, it is critical to realize that you take responsibility for the performance of the gadget.
This guide describes the current method of obtaining rights through Magisk, which is today the gold standard in the modification of Android.We will consider not only the technical steps, but also the pitfalls associated with Xiaomi’s policy regarding unlocking downloaders.
Preparation of the device and necessary tools
The first step is to carefully prepare the workplace and the smartphone itself, and you need a Windows computer, an original or quality USB cable, and a stable Internet connection, without these basic components, you can't do this or you can make communication errors with the device.
You need to install all available system updates on your smartphone to avoid driver conflicts. Also, be sure to create a full backup of all important data, since the process of unlocking the bootloader, which is a prerequisite, will completely destroy the information on the internal drive.
⚠️ Warning: Unlocking the bootloader will result in a complete reset of the device (Wipe Data.
To work, you will need the following software components:
- 📱 Drivers. ADB and Fastboot (Platform Tools).
- 🔓 The official Mi Unlock Tool.
- 🛠 Castom Recovery TWRP, adapted for the davinci model.
- 📦 Archive with a patched image of Magisk (file.apk renamed to.zip or img).
Unlocking the Bootloader bootloader
Without an unlocked Bootloader, root rights are impossible. Xiaomi has tight restrictions, so you can't just switch the switch to the menu. You need a Mi Account that must be linked to the device for a certain time.
Go to your smartphone settings, select About Phone, and click on the MIUI version several times to activate the developer menu. Then, in the advanced settings, find Mi Unlock Status and bind the acca.
⚠️ Attention: The waiting period for unlocking can be from 7 to 168 hours (7 days) from the moment of attachment of the account.
After the waiting time has expired, follow the following steps:
- 🔌 Turn off your phone and enter Fastboot mode by pressing the Volume Down buttons + Nutrition.
- 💻 Connect your smartphone to your PC and launch the Mi Unlock Tool under your account.
- 🚀 Press the Unlock button and wait until the process is complete. The device will reset and reset.
Successful unlocking is confirmed by the appearance of a hare icon that says Unlocked when the device is turned on, a critical step, without which the installation of the modified TWRP receptacle will be blocked by the security system.
Installation of custom TWRP Recovery
The squeezed recovery mode does not allow changes to the system partition, so you need to install TWRP. For the Mi 9T Pro model (codename davinci), there are specific versions of the recovery, taking into account the features of memory markup.
Copy the downloaded twrp.img image file into the ADB tool folder on your computer. Put your smartphone into Fastboot mode and connect it to your PC. Open the command line in the tool folder and enter a command to check the connection:
fastboot devicesIf the device is determined, perform a temporary loading of the recaveri command:
fastboot boot twrp_davinci.img💡
Use the "fastboot boot" command instead of "fastboot flash" to first check the TWRP without recording. If everything works, install it permanently through the menu of the recaveri itself.
Once you load into the TWRP interface, the first thing you need to do is allow modifications to the system partition. Swipe Allow Modifications. If you don't, the system will rewrite the recovery with the stock at the first boot, and at this point, it is recommended to back up the Boot and Vendor partitions in case you need to roll back.
Magisk installation and obtaining Root
The final step is to introduce a superuser binary, and modern Magisk is systemless, which allows you to hide rights from banking applications and Google Pay services.
Download the current version of Magisk.apk from the official GitHub repository. Rename the file extension from.apk to.zip (or use the installation function directly from APK in newer versions of Magisk Manager).
From the TWRP menu, select Install, find the Magisk file, and confirm the swipe installation. After the procedure is complete, press Reboot System.
☑️ Checklist of successful installation
Once you boot the system, look up the Magisk app on the menu. If it's installed (sometimes you need to re-install the APK over it), go inside and confirm that you've completed the setup. Now you have full access to the file system.
💡
Magisk Manager automatically manages superuser rights and allows you to hide root from applications that are incompatible with modified systems.
Comparison of methods of obtaining rights
There are several approaches to system modification, and it is important to understand the differences: some users are looking for ready-made firmware with already built-in rights, others prefer a clean installation.
| Method | Difficulty | Security | Flexibility |
|---|---|---|---|
| Magisk (Systemless) | Medium | Tall. | Maximum |
| Ready custom ROMs | Low. | Medium | Depends on the author. |
| Old SuperSU | Tall. | Low. | Weird. |
| KingRoot (online) | Low. | Critical | Absent. |
Using tools like KingRoot or OneClickRoot on modern Xiaomi devices is almost impossible due to the closed bootloader and security patches Android 10/11/12.
Magisk is based on the ability to use modules that change the behavior of the system without flashing it over. OTA-Updates (when configured correctly) and provides better compatibility.
Possible problems and solutions
During the modification of Xiaomi Mi 9T Pro users may encounter a number of common errors, for example, the device can go to bootloop (cyclic reboot) after installing an incompatible module.
If the phone doesn't boot, try entering Recovery mode (clamping Volume Up + Power) and running Wipe Cache/Dalvik. If that doesn't help, you'll need to flash the boot.img stock image over Fastboot.
⚠️ Note: If you receive a “Waiting for device” error in the Mi Unlock Tool, reinstall drivers manually through Windows Device Manager by selecting the Android Bootloader Interface model.
Another common problem is the non-functioning Widevine. L1, resulting in loss HD-quality in streaming services (Netflix) This is due to unlocking the bootloader and changing the keys. DRM. Bring it back. L1 It can only be re-locked with the bootloader and runoff firmware, but on global versions this often blocks the ability to re-unblock.
What if TWRP doesn’t see internal memory?
Also worth mentioning is the proximity sensor problem on the Mi 9T Pro. After customization, calibration may get lost. Use the engineering menu or special sensor calibration apps available in the Play Market to fix it.
