Root rights to Xiaomi Redmi 9T: a complete guide with analysis of risks and life hacks

Getting root rights to Xiaomi Redmi 9T (codenamed lime) opens up access to hidden Android features, but requires careful attention. This smartphone based on the Snapdragon 662 processor and MIUI firmware has its own nuances: from locking the bootloader to the features of the kernel. Unlike older Xiaomi models, you can’t just “push a button” – the process has become more complicated, but also safer.

Many users want to root to remove embedded applications, install custom firmware, or use Magisk modules to fine-tune the system. However, improper actions can lead to IMEI locking, loss of warranty, or a device brick. This article presents current 2026 methods tested at MIUI 14/15, given the latest Xiaomi security updates.

⚠️ Note: After obtaining root rights, banking applications (Sberbank, Tinkoff) and services with SafetyNet (Google Pay, Netflix) may stop working. To bypass the protection, you will need to additionally configure Magisk with the Universal SafetyNet Fix module.

1. Device Preparation: What to Do Before Unlocking

Before you start unlocking the bootloader and getting root, be sure to follow these steps – they will save hours on data recovery:

• 📱 Make a full backup through Settings → Additionally. → Backup or Mi Cloud. It's especially important to save IMEI, contact SMS.
• 🔋 Charge your phone to minimum. 70% — process 1-2 hours, and the discharge during firmware leads to failures.
• 🖥️ Install it on an Android PC SDK Platform-Tools (includes fastboot and adb). Alternative is Xiaomi's Mi Flash Tool.
• 🔑 Turn on Debugging. USB In Settings → The phone. → Version. MIUI (Press 7 times, then return to Settings → Additionally. → For developers.

Also check the firmware version in Settings → About Phone. Redmi 9T only works with firmware marked "Global" or "EEA." Chinese versions (CN) can cause problems with Google Services once unlocked.

⚠️ Attention: If your Redmi is 9T purchased in 2023-2026, it probably has a new type of bootloader (Anti-Rollback 4)+). Attempting to roll back on the old firmware will lead to irreversible locking of the device.

2 Unlocking the bootloader: official and informal ways

Without an unlocked bootloader, root is impossible to get. Xiaomi offers an official way through the Mi Unlock Tool, but since 2023 the process has become more complicated:

1. Linking your Mi Account to your device: Go to Settings → Xiaomi Account and log in. Make sure your phone is tied to your account for at least 7 days (a new Xiaomi requirement).
2. Unlock Request: Download Mi Unlock Tool, log in to the program and connect your phone in fastboot mode (clip Volume Down + Power).

If the official method is not suitable, there are informal methods (for example, through exploits in the Internet). EDL-but they require soldering equipment or paid service centers. IMEI or lock at the hardware level.

💡

If the Mi Unlock Tool gives you a "Couldn't unlock" error, try using the 5.5.224.30 version of the program, which often works where newer versions fail.

3. Selection of firmware: custom or patch for Magisk?

After unlocking the bootloader, you need to decide what to do next: install custom firmware (for example, LineageOS or Pixel Experience) or patch the regular MIUI through Magisk. The following options are relevant for Redmi 9T:

• 📱 Staff MIUI + Magisk: All Xiaomi features (camera, gestures) are saved, but patches need to be updated regularly.
• 🛠️ Brush firmware: Better performance and no bloatware, but bugs with VoLTE or Wi-Fi Calling are possible.
• 🔄 Hybrid variant: Installation MIUI from third-party developers (for example, MIUI EU) pre-stitched.

For beginners, the first option is a regular firmware patch. Download the latest version of MIUI Fastboot ROM for lime from the Xiaomi Firmware Updater site and check it for integrity (the file should weigh ~2.5-3 GB).

⚠️ Attention: Labeled firmware V13.0.1.0.SJQMIXM And the newer ones have enhanced DM-Verity protection, and they'll require Magisk Delta to patch them, with support for Magisk. init_boot.

4. Magisk installation and root obtaining: step-by-step instruction

When the firmware is ready, we start patching boot.img:

1. Extraction boot.img: In the unpacked firmware, find the file boot.img (It's in the image folder. Copy it onto your phone.
2. Patching through Magisk: 1. Install Magisk Delta on your phone (APK). 2. Open the app. → "Install" → "Select and patch a file". 3. Show the way to boot.img. 4. Wait for the file to be created. patched_boot.img download.
3. Patch boot firmware: Connect your phone to your PC in fastboot mode and execute the command: fastboot flash boot patched_boot.img fastboot reboot

After the reboot, check for root through the Root Checker app. If Magisk is not detected, repeat the steps with the cache clearing (fastboot erase cache).

5. Magisk setup and SafetyNet bypass

Even after successful rooting, many applications (such as Google Pay or Sberbank Online) will not work due to the SafetyNet trigger.

• 🔧 Install the modules in Magisk: Universal SafetyNet Fix (bypass check) MagiskHide Props Config (masking under a certified device)
• 📱 Enable MagiskHide in your settings and add to the list of apps you need to hide from root.
• 🔄 Restart your phone and check SafetyNet status through the app YASNAC.

The Redmi 9T also has a problem with encryption, and if you need a password after you have firmware, you can try:

1. Download to TWRP (if installed).
2. Select Wipe → Format Data (this will delete all data!).
3. Refresh the firmware.

💡

SafetyNet bypasses are not 100% guaranteed to be able to run banking applications, and some services (such as Tinkoff) use additional checks that Magisk cannot bypass.

6. Frequent errors and their solutions

Even with the correct following of the instructions, problems can arise, and here are the most common ways to eliminate them:

After all the manipulations, the phone stopped seeing. SIM-maps, check the integrity of the modem and nvram partitions. IMEI on the Redmi 9T utility SN Write Tool, but it requires authorization in EDL-Mode (requires an authorized Xiaomi account or paid access).

7. Alternative methods: TWRP and custom firmware

If patching boot.img seems complicated, you can go another way, install TWRP and flash Magisk or custom firmware through it. Redmi 9T is available:

• 🔧 Officially TWRP: TeamWin version 3.7.0. supports encryption, but may not work with newer versions MIUI.
• 🛠️ Informal assemblies: For example, TWRP by wzsx150 Risk: possible sensor bugs.
• 📱 Castom firmware: LineageOS 20 (Android 13), Pixel Experience (Android 14), ArrowOS. XDA.

The TWRP installation process:

1. Download. twrp-3.7.0_9-0-lime.img And put it in a folder with fastboot.
2. Download your phone to fastboot and execute: fastboot flash recovery twrp.img fastboot reboot recovery
3. In TWRP, file Magisk (rename the Magisk-apk file to.zip).

⚠️ Attention: MIUI 15 TWRP This can cause data loss due to a modified partition structure. Always backup through adb backup before experimenting!

8 How to Get Everything Back: A Recoil on the Original Firmware

If root rights are no longer needed or problems arise, you can return the phone to its original state.

1. Download the full Fastboot ROM for your model from the official Xiaomi website.
2. Unpack the archive and launch the script flash_all.bat (Windows or flash_all.sh (Linux/Mac).
3. If you want to lock the bootloader back, use the command: fastboot oem lock Attention: This will delete all data and return the phone to factory settings!

After rollback, check the status of the bootloader with the command fastboot oem device-info. If the answer Device unlocked: false, the device is completely back to the drain state.

💡

Recoiling back to the original firmware does not restore the warranty. Xiaomi can determine whether the bootloader has been unlocked by logs, even if it is locked back.
