Modern smartphones, despite their power, are often limited by the software frameworks that the manufacturer sets. Getting root rights to Xiaomi Redmi 9 opens the door to a world of unlimited possibilities, allowing users to remove system software, overclock the processor and install specialized modules. However, this process requires care, since interference in the system partition can lead to a loss of warranty or inoperability of the device if the sequence of actions is disrupted.
The procedure for obtaining superuser rights is based on the use of the Magisk utility, which is implemented in the boot section of the device. To successfully implement this plan, you will need not only the smartphone itself, but also a personal computer with ADB and Fastboot drivers installed. It is critical to understand that unlocking the bootloader, which is the first mandatory step, completely erases all data from the internal memory of the device.
Before you start technical manipulation, you need to understand all the risks. Xiaomi Redmi 9 is a popular model, and there are many proven methods of modification for it, but the security of your data is now a priority. In this article, we will discuss in detail each step, from applying to the final validation of rights.
Device preparation and backup
The initial phase is the foundation of the entire operation. Without proper preparation, the next steps may become impossible or lead to the loss of important photos and contacts. The first thing you need to do is create a complete backup of all data, since the process of unlocking the bootloader initiates a complete reset of the smartphone to the factory settings.
Use built-in tools MIUI To save data to an external drive or to a cloud storage, also make sure that the battery is charged at least 60% so that a sudden power outage does not interrupt the firmware process at the most critical time. USB-cable you will use to connect to your PC, as poor contact can cause driver error.
⚠️ Warning: Unlocking the bootloader will void the manufacturer's official software warranty.If the smartphone is warranty, think twice before starting the procedure.
Once you create a backup, you need to activate the developer mode. To do this, go to the settings, find the "About Phone" item and quickly click 7 times on the MIUI version. Then, in the "Developers" menu that appears, turn on USB debugging, which will allow the computer to exchange commands with the operating system of your Redmi 9.
- 📱 Charge the battery of the smartphone at least to 60-70%.
- 💾 Make a full backup of your data to your PC or cloud.
- 🔌 Use original or quality USB-linkage.
- 🔓 Link your Mi Account to your phone number in your device settings.
Unlocking the Bootloader bootloader
The most difficult and longest stage for owners of Xiaomi equipment is waiting for permission to unlock. You will need to download the official Mi Unlock Tool utility to your computer and log into your account. After connecting your smartphone in Fastboot mode (clamping down the volume button when turned on), the program will check the status of the device.
If you've recently linked your account, the system will require you to wait a certain amount of time, usually 7 to 168 hours, and this is the company's security mechanism to prevent devices being stolen and flashed, and during this period, don't log out of your phone account and reset your settings, or you'll have to re-start the timer, and successful unlocking will be confirmed by the "Unlocked successfully" message in the utility.
Once you're "Unlocked," the phone will automatically restart and clear the memory, and you'll have to reset the system, restore the data from the backup, and re-enable the USB debugging, and now the bootloader is ready to install the modified backup.
- ⏳ Be prepared to wait 7 to 168 hours after you submit your application.
- 🔒 Do not delete your Mi Account and SIM-card.
- 🔄 After unlocking the phone will be completely cleaned, you will need to re-set up.
Installation of custom TWRP Recovery
The standard recovery menu does not allow you to make changes to system partitions, so you need to install TWRP (Team Win Recovery Project). For the Redmi 9 model (codenamed lancelot), you need to find a stable version of the image. Download the twrp.img file and place it in the folder with ADB tools on your computer.
Put your smartphone into Fastboot mode and connect to your PC. Open the command line in the tool folder and type in the command to check the connection: fastboot devices. If the serial number is displayed, you can start the temporary firmware recovery command fastboot boot twrp.img. This will start TWRP without permanent recording, which is safe for the test.
☑️ Checklist before firmware TWRP
In TWRP, the first thing you need to do is prevent the backup of the firmware from going back to the stock, drag the slider at the bottom of the screen, allowing modifications. If you don't, the first time you reboot, the system will restore the standard menu, and then you can temporarily flash the TWRP permanently, or you can immediately switch to installing superuser rights if you use the boot image patch method.
⚠️ Attention: When installed TWRP Make sure the recovery version is strictly consistent with your Android version and processor model. Using an inappropriate image can lead to a "brick" of the device.
Magisk and Root Rights Installation Process
There are two main methods: firmware ZIP-archive TWRP or patching a boot image (boot.img). The second method is considered more reliable than the current versions. MIUI. You'll need an exact copy of the stock firmware installed on your phone. boot.img And copy it to your phone.
Install the Magisk app (rename the apk file to zip or simply install it as an app). From the app menu, select "Install» → «Select and patch the file" and specify the previously copied boot.img. The program will create a new file magisk_patched.img bootloader.
fastboot flash boot magisk_patched.img
fastboot rebootCopy the patched file back to your computer, put your phone in Fastboot mode, and execute the firmware command above. After the reboot, the Magisk icon appears in the system. If the app shows that Magisk is not installed, click "Additional" and select the full installation, then restart again.
- 📥 Download an exact copy of stock firmware for your version MIUI.
- 🔧 Use the “Patching File” feature in the Magisk app.
- 💻 Sweep the patched image through Fastboot.
- ✅ Check root status in the application or through the terminal.
💡
If the phone goes into a cyclical reboot after installing Magisk, boot to TWRP and make wipe data, or restore the original boot.img via Fastboot.
Comparison of methods of obtaining rights
Users often argue about which way is better: using automated programs like KingRoot or manually installing Magisk. Automatic utilities often contain advertising, transmit user data and do not give full control over the system. Manual method is more complicated, but ensures the purity of the system and security.
The table below compares the characteristics of different approaches to modifying the Xiaomi Redmi 9. This will help you choose a strategy that is suitable for your tasks, whether it is simply removing ads or deep customization of the kernel.
| Method | Difficulty | Security | Full access |
|---|---|---|---|
| Magisk (Manual) | Tall. | Tall. | Yes. |
| KingRoot / OneClick | Low. | Low. | Partial |
| Unlocked BL | Medium | Medium | Only with TWRP. |
💡
Manually installing Magisk via boot.img patching is the only modern way to get hidden root rights bypassing bank application detectors.
Checking rights and possible problems
Once installed successfully, you need to verify the result. Download the Root Checker app from the Play Market or use the terminal. Enter the su command. If the system requests permission to grant superuser rights and issues the # symbol instead of $, then the procedure was successful.
However, users often face problems with banking applications. Google Pay and banking software may refuse to work on modified devices. To solve this problem, Magisk needs to activate Zygisk and enable the hide of the application list.
⚠️ Note: Some banking applications may be permanently blocked on a device with an unlocked bootloader, regardless of root rights.
If after all the manipulations the phone behaves unstable, there are reboots or heating, try to clear the Dalvik cache in the TWRP menu. In extreme cases, you can always return to the factory state by restoring the original boot.img and locking the bootloader back, although the last action on custom software can lead to a complete failure of the device.
