Modern smartphones, even budget smartphones, have a huge hidden potential that is often blocked by the manufacturer. Xiaomi Redmi 9C NFC is no exception, offering users an affordable platform based on the MediaTek processor. However, the standard limitations of the Android system do not allow owners to make deep changes to the device, remove system debris or install specialized modules.
Obtaining superuser rights opens the door to full control of the gadget, not only allowing you to remove pre-installed applications that cannot be uninstalled by standard methods, but also running powerful programs to automate, modify the kernel and fine-tune the interface, a process that requires care, because interfering with system files always carries certain risks.
Before proceeding with active actions, it is necessary to clearly realize that unlocking the bootloader and subsequent modification of the system will void the official warranty. In addition, banking apps and services that use Google Pay or Mi Pay can stop working without further manipulation to hide root rights. 9C.
Preparation of the device and necessary tools
Starting any firmware modification process requires careful preparation of the workplace and the smartphone itself. Ignoring the preparatory stage can lead to you being stuck in the middle of the way, unable to roll back the changes. First of all, make sure that your device is charged at least 60%, as a sudden power outage during firmware is fatal.
You will need quality. USB-A cable, preferably original or certified, that is guaranteed to transmit data, not just charge the battery. ADB And Fastboot drivers, without which the PC will not see the phone in boot mode. VCOM, which often have to be installed manually through the Device Manager.
☑️ Pre-launch check
Make sure to back up all your important data, because the process of unlocking the bootloader will completely destroy the information on the internal drive. Copy photos, contacts and documents to an external medium or to the cloud. Without this procedure, recovering personal files after reset will not be possible.
Unlocking the Bootloader bootloader
A fundamental step to obtaining root rights is to unlock Bootloader. While the bootloader is locked, no modified system or recovery can be installed on the device. In Xiaomi smartphones, this process is strictly regulated and requires an account to be linked to the device through an official utility.
First, you need to register with Mi Unlock and apply for unlocking. Once the application is approved (which can take 3 to 15 days), you need to log into the same Mi Account in the phone settings, in the "Developers" section, only after that the utility on the computer will allow the unlock procedure.
⚠️ Note: The process of unlocking the bootloader automatically performs a full data reset (Wipe Data). All your photos, applications and settings will be permanently deleted, so backup is a must.
The process is Fastboot mode. You turn off your phone, press down and power at the same time until the logo of the hare repairing the android appears, and if you connect the cable to your PC, you'll see the status of the device and the Unlock button, which will start the process.
Installation of custom TWRP Recovery
Xiaomi’s standard recovery menu has extremely limited functionality and does not allow you to install third-party zip archives or make full partition backups. To implement superuser rights, we will need a TWRP (Team Win Recovery Project) utility, adapted specifically for the Redmi 9C model (codename: lancelot).
Finding the right version of the recovery is critical. Because the device runs on a MediaTek Helio G35 chip, you need to look for the build for this processor and this model. Installing the wrong image can lead to the device "bricking" so check the sources of the files.
The firmware is run through the Windows command line using Fastboot mode. The command is as follows:
fastboot flash recovery twrp-lancelot.imgIt's important to note that you can't boot into the normal system right after you've run the firmware, because the regular recap will overwrite the custom one, you need to immediately press the button combination to enter recovery mode, usually by pressing the volume buttons "Up" and "Power" at the moment of vibration when you turn on.
What happens if TWRP doesn’t start?
Magisk installation to get a Root
The most modern and secure way to obtain superuser rights today is to use the Magisk manager. Unlike the old methods (SuperSU), Magisk works systemlessly, which allows you to bypass many security checks and leaves the system partition intact.
To install you will need to download the current APK-Magisk file, rename its extension to.zip (in some versions) TWRP It's not required, but for reliability, it's better to have a zip archive and upload it to the phone's internal memory. TWRP, Select the "Install" item, find the file and confirm the installation of the swipe.
The installation process takes a few seconds. Once successful, the green "Success" will appear. Then you click "Reboot System" to restart the device as normal. If successful, the Magisk icon will appear in the application menu.
| Component | Appointment | Post-installation status |
|---|---|---|
| Bootloader | Loader OS | Unlocked (Unlocked) |
| Recovery | Recovery environment | TWRP (Custom) |
| Magisk | Root rights manager | Established and active |
| System Partition | System section | Unchanged (Systemless) |
Magisk setup and bypassing bank checks
After obtaining the rights, many users face a problem: banking applications stop working, citing root rights or a modified system. Magisk has a built-in concealment mechanism that allows you to mask the presence of superuser rights from specific applications.
In Magisk settings, you need to activate the "Zygisk" function (in new versions) or "MagiskHide" function. Once you turn on, you need to reboot. Then you need to find your banking applications (Sberbank, Tinkoff, Google Pay) in the process list and tick them against them, which will hide the fact that they have root rights.
💡
For maximum concealment effect, it is also recommended to rename the Magisk Manager package through the application settings before enabling hiding, as some banks block the very fact of having an installed manager.
It is also worth turning on the MagiskHide Props Config module if applications require a Google Play Integrity certificate or a specific device fingerprint, which will emulate the behavior of a conventional, unmodified smartphone.
⚠️ Warning: The constant fight against root-rights detection is an "arms race": Updates to banking applications can temporarily break the job of hiding, requiring updates to Magisk modules or waiting for patches from the community.
Possible problems and ways to solve them
The process of modifying the Xiaomi Redmi 9C NFC rarely goes perfectly smoothly for all users. Often there are situations where the phone goes into a bootloop (cyclic reboot) or TWRP does not see internal memory. In the case of a bootloop after installing the module, safest mode in Magisk or removing the problem module through the file manager in TWRP usually helps.
If your computer stops seeing your phone in Fastboot mode, try replacing it. USB-cable or switch to another port USB 2.0 (Ports 3.0 sometimes cause problems with old drivers) Reinstallation of MediaTek drivers also helps. VCOM "Debugging by" mode USB".
If the touch screen doesn't work in TWRP, it means you've installed the wrong version of the Recovery, you need to find the build where the touch screen is fixed, or use volume control (volume up/down - navigation, power - selection).
💡
The most common mistake is to run a recovery firmware not designed for your Android version or regional firmware (Global/China/EU), which results in a broken touch or Wi-Fi.
