Xiaomi’s mobile devices are famous for their price-performance ratio, but the standard MIUI shell often limits the capabilities of advanced users. Obtaining superuser rights, or Root, opens up access to system files, allowing you to remove preinstalled software, install modified firmware and fine-tune the processor. Owners of the Redmi 9 NFC model often look for ways to activate these functions without using a computer, which makes the process more mobile and convenient.
It is worth noting that the procedure of unlocking the bootloader and implementing administrator rights on modern Android smartphones is a complex technical process, fraught with certain risks. Despite the fact that you can perform all the actions directly from the phone, you will need a stable Internet connection, a fully charged battery and attention to detail. Any wrong action can lead to a loss of warranty or, in the worst case, turn the device into a brick.
In this guide, we will discuss each step in detail, from preparing a Mi Account to the final installation of the Magisk rights manager. NFC-This is a module in this model, as getting Root access often affects the operation of contactless payment. Follow the steps consistently to minimize risks and successfully modify your gadget's software.
Preparation of the device and necessary tools
Before you start any manipulation of the system partition, you need to do a thorough preparation. The first step is to create a full backup of all important data, since unlocking the Bootloader will lead to complete removal of information from the internal drive. Use cloud services or external drive to save photos, contacts and documents.
The second critical point is battery power: the charge level should be at least 70-80% so that during the process of firmware or unlocking the smartphone suddenly turns off, and also make sure you know the password from your Mi Account and Google account, as after the reset, the system will require them to confirm ownership of the device.
You'll need to download and install a few specialized applications directly from the Google Play store or trusted sources, and the main tool will be the Termux app for emulating the terminal, as well as a file manager with access to system folders, without which you can't execute unlock scripts from a mobile device.

- ☁️ Create a full backup of data to an external medium or to the cloud.
- 🔑 Make sure you remember the passwords from your Mi Account and Google Account.
- 📥 Download the necessary APK-Files: Termux, File Manager, Magisk Manager.
⚠️ Warning: Unlocking the bootloader automatically voids the manufacturer's warranty on the device. If your smartphone is in warranty service, think twice before starting the procedure.
Unlock Bootloader bootloader via Mobile Phone
The foundation for obtaining Root rights is an unlocked bootloader. In the Xiaomi ecosystem, this is done officially through the company's servers, but the standard method requires a PC. However, there are workarounds that allow you to send an unlock request using only a smartphone and special utilities that emulate the device. ADB-team.
First, you need to activate the developer mode. To do this, go to the settings, select About Phone, and quickly click on the version seven times. MIUI. Once you have the "You've become a developer" label, go back to the main settings menu, find the "Advanced Settings" section, and open "Developers" section. USB» and «USB-installation».
Next, link your account to your device. In the same developer menu, find Mi Unlock Status and click Add Account and Device. The system will require a Wi-Fi or mobile connection. Once successfully linked, it may take 7 to 168 hours (week to month) before the server allows you to unlock, which is the time required for your device to be secure.
When the waiting time is up, you can start unlocking. Using a terminal emulator, you need to input commands to put your phone into Fastboot mode. Unlike a PC where we use a cable, here we use a software restart. The command looks like an adb reboot bootloader, but it is executed through the terminal on the debugging device itself.
adb reboot bootloaderAfter switching to Fastboot mode, you need to use a specialized Mi Unlock client application adapted for Android, which allows you to send a signal to the unlock server, and if the server confirms the status of the device, the bootloader will be unlocked, and the phone will automatically reset to the factory settings.
Installation of custom TWRP recavator without a computer
Once the bootloader is successfully unlocked, the standard Recovery menu becomes insufficiently functional to implement superuser rights. We'll need to install custom Recovery, and the most popular solution is to use the custom recovery. TWRP (Team Win Recovery Project. ZIP-archives, make full backups and manage the file system.
The process of installing TWRP on Redmi 9 NFC without a PC requires downloading a special.img image adapted specifically for the code name of your model (for example, lancelot). It is important to download a file that corresponds to your version of Android and the type of processor. Trying to install an image from another model will result in a touch screen failure or a complete blockage of the download.
The firmware uses a fastboot command that runs through the terminal, and since the cable is not in use, we use the flash method from inside the system or through recovery mode if it is possible to download the image temporarily.
fastboot flash recovery twrp-3.x.x-x-lancelot.imgHowever, on modern Xiaomi devices with dynamic partitions, a simple flash command may not work. twrp-image.img. After loading into TWRP You must immediately install ZIP-file with the recovery itself to the recovery section to save it after the reboot.If you don't, the standard Xiaomi recap will rewrite it TWRP first-time.
☑️ Pre-firmware check TWRP
Magisk integration for Root rights management
The current standard for obtaining superuser rights is Magisk. Unlike the old methods (SuperSU), Magisk works systemless, which means it does not modifies the system partition directly. This allows you to bypass security checks in banking applications and games that do not like modified devices.
For installation download the current APK-Magisk file and rename its extension from.apk to.zip. Then download to the previously installed menu TWRP. In the main menu, select the item "Install" (Install), find the prepared ZIP-archive and confirm the swipe slider installation.
Once installed successfully, press the Reboot System button. The first boot can start longer than usual, which is normal because system libraries are reassembled. Once turned on, you'll see a new Magisk icon. When you open it, you should see the version of the installed manager, which confirms that you have successfully gained Root access.
| Component | Appointment | Risk of error |
|---|---|---|
| Bootloader | Loads the OS, blocks unauthorized changes | High (brick when failure) |
| TWRP | Average (data loss) | |
| Magisk | Low (can be removed) | |
| ADB/Fastboot | Medium (command error) |
Set up security and work with NFC after rooting
One of the main problems after getting Root on Xiaomi Redmi 9 NFC It's a contactless payment that's gone, and banking apps and Google Pay (or their equivalents) detect the superuser's rights and block the work. NFC-In order to get back the functionality, you have to hide the fact that the rooting is happening.
In the Magisk app, go to the settings (cog at the top) and turn on the Zygisk function. Then look for the DenyList option, which includes all banking apps, Google Pay, and Google Play system services, which will cause Magisk to hide the Root rights for selected programs.
In addition, Universal SafetyNet Fix may need to be installed via Magisk, which replaces the security certificate data to convince applications that the device is not modified, and once the module is installed and rebooted, a SafetyNet verification must be confirmed in the Google Play Services app.
What happens if the NFC stops working?
⚠️ Note: Root concealment modules are not 100% guaranteed. Some banking applications may stop working permanently on a rooted device and can only be returned to work completely by removing Root and returning to stock firmware.
Possible problems and ways to solve them
Redmi 9 users may experience a cyclic bootloop, where the phone constantly displays the MI logo and does not boot further, in which case you need to go to TWRP (pressing the power and volume button) and clean the Dalvik/Cache cache or restore a full copy of the system if it was made in advance.
Another common problem is a broken touch screen in Recovery mode, which indicates that the wrong version of TWRP was installed. The solution is one: find and reflash an image strictly corresponding to the Android version and the region of the device, and there may be problems with Wi-Fi or Bluetooth after installing custom cores, which is solved by returning the stock core (boot.img).
If the device still went into a deep bootloop and does not respond to buttons, the only way to save can remain EDL (Emergency Download Mode), logging into it on Redmi 9 often requires disassembling the case and closing contacts on the board, or using special authorized Mi accounts for firmware through the PC, which again brings us back to the need for a computer.
💡
Tip: Before any experiments, make a full backup of the EFS and Persist partition via TWRP. These sections contain IMEI and sensor calibration, their loss will make the phone unusable for communication.
Concluding recommendations and conclusions
Getting Root rights to Xiaomi Redmi 9 NFC without a PC is a challenge for confident users who are willing to take responsibility for the device. While modern tools allow you to do without a computer, the risk of error remains high, the main advantage of this approach is mobility and independence from having a PC at hand at the right time.
But it's worth weighing the pros and cons. If you want Root rights for just one specific program, consider whether the risk of losing warranty and potential security issues is worth it. For most users, standard MIUI features are enough. But if you're an enthusiast, an unlocked bootloader will open the door to a world of full customization of Android.
💡
The main conclusion: 90% of the success of the operation depends on the exact selection of files (TWRP and Magisk images) for a particular version of the firmware and device region.
Remember that technological progress does not stand still, and methods may change with the release of new versions of MIUI. Always check the relevance of information in the profile forums before starting actions. Good luck in modifying your smartphone!
