Many owners of budget smartphones, such as Xiaomi Redmi 9C NFC, sooner or later face the limitations of the standard shell MIUI. The desire to remove system debris, install custom themes or modify the core of the system pushes users to find ways to expand the functionality of the device. Obtaining superuser rights (Root) is the only legal method to gain full control of the Android operating system installed on your gadget.
But the Redmi 9C is a MediaTek processor that makes its own adjustments to unlock and firmware compared to the more popular Snapdragon chipsets. You go from applying for MIUI Unlock Tool to installing a dedicated bootloader, Magisk. It's important to understand that any interference with system files can lead to unstable operation if you do not follow the exact sequence of actions.
Before we get to the practical steps, we need to understand the responsibility: Administrator rights open the door to powerful applications, but also make the device vulnerable to careless handling. In this article, we will take a detailed look at each step to minimize the likelihood of errors and turn your smartphone into a powerful tool in skilled hands.
Preparation of the smartphone and the necessary tools
You should start with a thorough preparation of the workplace and the device itself. You need a Windows computer that is working. USB-cable (preferably original or certified) and stable Internet connection. All available system updates must be installed on the smartphone via the Settings menu → The phone. → Update the system to avoid conflict versions in the process.
A critical step is to create a full backup of the data. When you unlock the bootloader, which is a prerequisite for obtaining Root, all data on the internal drive will be permanently deleted. Save contacts, photos and important documents to the Google Drive cloud or to an external hard drive. Ignoring this step can lead to the loss of personal information.
⚠️ Warning: Unlocking the bootloader officially removes the warranty from the device in most service centers. L1, Streaming services (Netflix, Amazon Prime) can stop playing content in the Internet. HD-quality.
To work, you will need to download and install specialized software on your PC, primarily ADB and Fastboot drivers, which provide communication between your computer and your phone in debugging mode, and you will also need the Xiaomi Mi Unlock Tool to officially unlock the bootloader and an archive with firmware corresponding to your current version of MIUI.
Don't forget to activate the developer mode on the phone itself. Go to Settings → About the phone and quickly click on the build number seven times. Then the "Forward" menu will show a "Developers" item where you need to turn on "Debugging on USB" and "Factory Unlock." Without these settings, the computer will simply not see the device in the right mode.
The procedure for unlocking the bootloader (Bootloader)
Unlocking the bootloader is a fundamental step without which superuser rights are impossible to set up. In the Xiaomi ecosystem, this process is strictly regulated by the manufacturer. Once you have your Mi Account tied to your phone settings, you will have to wait 7 to 168 hours (usually 168 hours, that is, 7 days) before the server allows you to unlock, a security measure designed to protect users from device theft.
After the wait period, you need to transfer the smartphone to Fastboot mode. To do this, turn off the device completely, and then press the volume buttons "Down" and power at the same time. The screen will show a picture of a hare repairing an android, which indicates a successful transition to firmware mode. USB-cable.
- 🔓 Run the Mi Unlock Tool program on your PC and log in to the same Mi Account that is linked to your phone.
- 🔓 Press the Unlock button and wait for the process to be completed, which can take a few minutes.
- 🔓 After successful unlocking, the phone will automatically restart and reset to factory settings (Wipe Data).
The utility can give out various error codes during the unlock process, the most common is “Couldn’t verify device.” It means that the phone is not tied to the account or the necessary waiting time has not passed, in which case you should not try to hack the system using third-party methods, since for the MediaTek processor this can result in complete inoperability (brick).
⚠️ Warning: Do not interrupt the unlocking process or disconnect the cable until a success message appears. Interrupting the recording to the bootloader section can cause the phone to stop loading at all (Hard Brick).
Once successfully unlocked, the bootloader will change its status, and when the phone is turned on, the sign will appear in front of the MI logo, saying "Unlocked" or an image of an open lock, which signals that the first and most difficult stage has passed, and now you can move on to installing superuser rights.
Installation of custom TWRP Recovery
The standard Recovery menu in Redmi 9C does not allow you to install modified system files or Root patches. This requires custom recoveries, and the gold standard here is TWRP (Team Win Recovery Project).
Upload the image file (usually with the.img extension) to the tool folder ADB Put your smartphone in Fastboot mode (down buttons» + «Power") and connect it to the PC. Open the command line in the folder with ADB And you type in the connection check command: fastboot devices. If you see the serial number of the device, then the connection is correctly established.
fastboot flash recovery twrp-lancelot.img
fastboot boot twrp-lancelot.imgThe first command records the TWRP image in the recovery section, and the second command forces the phone to run immediately in recavator mode, which is an important nuance: if you just reboot the phone after the firmware in the usual way, the standard MIUI system can overwrite the custom recavator with its stock counterpart, so you need to log in to TWRP immediately.
In the TWRP menu, the interface will be touch-sensitive. First, swipe for modification permissions. Then, you should backup the current system (Backup section) by selecting Boot, System, and Data sections. This will take a few minutes, but will create a rollback point in case something goes wrong when you install Root rights.
💡
If TWRP asks for a password when you sign in, use your phone's screen unlock password. If the password doesn't fit, it may be that encryption is interfering with the work, and you'll need to format the Data partition, which will delete all files.
Magisk installation and obtaining Root rights
The modern standard for obtaining superuser rights is the Magisk utility. Unlike the old methods (SuperSU), Magisk works on the principle of systemless, that is, it does not make changes to the system partition directly, which allows you to bypass some security checks and run banking applications. APK-Magisk file and rename its extension to.zip for installation via recovery, or use the "Install" function inside the application itself after booting the system.
Consider the installation method through TWRP, As it is the most reliable for initial setup, copy the Magisk installer file (e.g, Magisk-v26.0.apk or.zip) for internal phone memory or connected USB-flash drive (if supported) OTG). On the main menu. TWRP select “Install”, find the Magisk file and confirm the installation of the slider swipe.
- ⚙️ Wait for the firmware process to be completed, the log should say “Done».
- ⚙️ Press the “Reboot System” button to restart to a regular operating system.
- ⚙️ After downloading, find the new Magisk icon in the application menu and open it.
When you first start up, Magisk may request an additional environment recovery (Additional Setup). Accept that, the phone will reboot again. After the second turn on in the Magisk application, the installed version number should be displayed in the Version bar, and the status of the Root should be active. This means that you successfully obtained superuser rights to the Xiaomi Redmi 9C NFC.
☑️ Checking the successful installation of Root
Now you can install modules, block system-level ads, make full application backups of data, and change system files, but remember that with superuser rights, you become the only one responsible for system integrity.
Security setting and working with modules
Root access requires a rethink of security. Any application you give superuser permissions to has unlimited access to all the data on the device. Magisk has a Superuser list where you can see requests and grant permissions. Always check why an application needs admin rights.
One of the main problems for root users is the work of banking applications and Google Pay, which use the service Google Play Protect and check the integrity of the system (SafetyNet/Play Integrity! To hide the presence of Root, Magisk must enable “Zygisk” and “DenyList” in its settings.
⚠️ Warning: The constant battle with the Root detector is an arms race. After another update to a banking app or Android system, the Root hideout may stop working.
You can also install functionality-enhancing modules through Magisk, such as modules to improve sound, change system fonts or overclock the processor. However, on the MediaTek Helio G35 processor installed in the Redmi 9C, you should be careful with performance-impairing modules so as not to cause overheating and trottling.
To manage files with superuser rights, it is recommended to use advanced file managers such as MT Manager or Root Explorer, which allow you to see hidden system folders and edit configuration files, but even here the rule is: do not change what you do not know.
Possible problems and ways to solve them
The process of modifying the system rarely goes perfectly smoothly for all users, and the most common problem is a bootloop, where the phone is endlessly rebooted on the manufacturer's logo, which can happen if the TWRP version does not match the Android version or if an incompatible Magisk module has been installed.
If your phone is in a bootloop, try recovery mode (Up + Power buttons when your phone is off). In TWRP, select Wipe and cache (Dalvik / ART Cache). If that doesn't work, you'll have to do a full reset (Format Data), which will delete all the data, but can bring the system back to life. At the very least, only flashing the stock firmware through the Mi Flash Tool in Clean All mode will help.
| Problem. | Probable cause | Decision |
|---|---|---|
| Phone not visible on Fastboot | Not installed drivers or bad cable | Replace the cable, reinstall ADB drivers |
| Mi Unlock Mi Mi Mi Mistake 10008 | Problems with the server or account | Wait 24 hours, check the Internet, re-link your account |
| Magisk doesn't see Root | Incorrect setting or conflict | Reinstall Magisk, check the status of the bootloader |
| The camera's not working well. | Loss of drivers or software conflict | Make Wipe Data in TWRP or Return Stock Boot |
Another common situation is the loss of broadband connectivity or IMEI after manipulation. On modern Xiaomi devices, this is less common, but the risk of damage to the persist or modem partition exists, which is why it is so important to do a full backup of partitions through TWRP before any action.
What do I do if IMEI is missing?
In conclusion, getting a Root on a Redmi 9C NFC is a great way to extend the life of a device by installing light custom firmware or removing unnecessary software. However, this path requires care, accuracy and a willingness to take responsibility for your actions. If you did everything right, your smartphone will open from a new side.
💡
The key to success is the exact matching of TWRP, firmware and Magisk versions. Never use files that are intended for other Xiaomi models, even if they look similar.
