The procedure for obtaining extended access rights on budget devices of the Redmi series often raises questions from users who want to squeeze the most out of their gadget. the Redmi 9A model, built on the basis of the MediaTek Helio G25 processor, has its own specific features that must be considered before starting any manipulation with the system partition.
Unlike Snapdragon, it uses slightly different firmware and recovery techniques, which requires a more careful approach to tool selection. Getting root permissions is not just installing one program, but a complex process that involves unlocking the bootloader and implementing a modified boot image.
It should be understood that interference with the structure of the MIUI operating system always carries certain risks, but with all security algorithms, the likelihood of turning a phone into a brick is minimized. Below we will discuss in detail each stage of preparation and implementation of superuser rights.
Device preparation and data backup
The first step is to carefully prepare the workplace and the smartphone itself. You'll need a Windows computer that's working. USB-cable and stable Internet connection. Before starting work, be sure to create a full backup of all important data, since the process of unlocking the bootloader involves completely resetting the device to factory settings.
Charge the smartphone battery to a minimum of 60-70%. Sudden power outage at a critical moment of firmware can damage the system partitions, the restoration of which will require complex hardware intervention.
- 🔋 Charge the Redmi battery 9A above 70% for stable employment.
- 💾 Save contacts and photos to an external drive or to the cloud.
- 🔌 Use an original or quality certified cable.
- 💻 Install the drivers. ADB and Fastboot on your computer.
⚠️ Note: Unlocking the Xiaomi bootloader automatically erases all data from the internal drive.Photos, contacts and applications will be deleted without the possibility of recovery through standard means.
Make sure you're tied up. SIM-card to the Mi Account and included in the developer settings the items "Factory unlocking" and "Debugging by USB". Without these preconditions, further steps will not be possible.
Unlocking the bootloader (Bootloader)
The foundation for obtaining superuser rights is an unlocked bootloader. Xiaomi uses its own Mi Unlock Tool to authorize this process. You need to download the official version of the program from the developer's website and log into your Mi Account on your computer.
Put your smartphone into Fastboot mode, pressing both the power and volume buttons simultaneously. Connect the device to your PC and press the Unlock button in the utility. The official unlock procedure may require waiting 7 to 168 hours from the moment you bind your account, which is the manufacturer's security mechanism.
During the unlocking process, the phone will be rebooted several times. Do not interrupt the connection to the computer and monitor the status in the program window. Successful completion of the stage is confirmed by the corresponding message and a clean Android system after turning on.
Installation of custom TWRP Recovery
To implement access rights, we will need a modified recovery menu. Standard recovery mode does not allow you to install files that are not signed with Xiaomi digital keys. For Redmi 9A (codename dandelion), you need to find a specific TWRP build adapted to the MediaTek processor.
Upload the.img image file to the ADB tool folder on your computer. Open the command line in this folder and enter the command to go to fastboot mode if the device isn't already there: adb reboot bootloader.
Next, the firmware command of the image of the recaveri is performed:
fastboot flash recovery twrp-dandelion.imgIt is important to avoid automatic booting immediately after firmware, as the stock system can overwrite the custom Recovery back to the standard. Use a combination of buttons to log in to recovery immediately after the command is completed or run the fastboot boot twrp-dandelion.img command for a temporary start.
- 📥 Download the current assembly TWRP It's for the dandelion model.
- 🖥️ Check that the device is displayed in the command line.
- 🚫 Do not agree to install system updates in TWRP.
- ✅ Backup the Boot section before any changes.
Magisk installation process for root access
The most modern and secure way to obtain rights is to use the Magisk Manager, which allows you to implement superuser rights in a systemless root, which is important for the operation of banking applications and Google services.
Download the installation. APK-Magisk file and rename it to.zip (or just copy it) APK in memory of the telephone, if TWRP install APK directly, but more reliably use a zip archive or image patch. TWRP.
In the recovery menu, select "Install" and specify the path to the Magisk file. Confirm the installation by swipe. After the procedure is complete, click "Reboot System." The system can update when you first boot, which is normal.
☑️ Checklist of Magisk installation
Once you boot, look for the Magisk icon in the application menu. If the application opens and shows the version and the status "Installed", then the procedure was successful. You can activate additional modules in the application settings to expand the functionality.
License Check and Security Setup
To make sure that the work is correct, install a license checker app, such as Root Checker, run the test and get a status confirmation, and now you can manage system files, delete preinstalled software, and configure the processor.
However, root rights require increased vigilance, and if a malicious user or malware gains access to a superuser, it can cause irreparable harm. In Magisk settings, enable "MagiskHide" (or its new version) to hide rights from banking apps and anti-cheat games.
| Parameter | Prior to obtaining rights | After receiving the Root |
|---|---|---|
| Access to the system | Limited. | Complete. |
| Removal of system applications | Impossible. | Maybe. |
| Work of banking applications | Stable. | Requires concealment settings |
| Manufacturer's guarantee | It's still there. | Cancellation. |
⚠️ Warning: Having an unlocked bootloader and root rights makes the device vulnerable. Do not install applications from unverified sources and read requests for superuser rights carefully.
Possible problems and ways to solve them
In the process of modifying the firmware Redmi 9A Users may encounter a number of typical difficulties, and there is often a problem with MediaTek drivers on Windows 10 and 11. BROM or Preloader, try disabling digital signature check drivers or using another USB-port.
Another common mistake is to “boot” after installing the wrong recovery image, in which case logging into Fastboot mode and running a stock boot or recovery image through the fastboot flash boot.img command will help.
What if Magisk doesn’t see root?
Also worth mentioning is the Widevine L1 issue. Once the bootloader is unlocked, the DRM level often drops to L3, which limits HD-quality content playback in some streaming services. It is extremely difficult, and sometimes impossible, to return L1 on an unlocked bootloader without specific backups.
💡
Save the original boot.img image of the stock firmware immediately after unlocking.This is the only way to easily return to factory status without completely flashing through MiFlash.
Concluding recommendations and outcomes
Getting the root rights to the Xiaomi Redmi 9A opens up broad horizons for customization, but requires the user to be technically literate. You have gained full control of the device, but with it you have taken responsibility for its stability.
Backup important data regularly and keep an eye on the development community updates for your model. The Android world is constantly changing, and what worked yesterday may require a new approach today.
💡
The main conclusion: Root on Redmi 9A is a powerful tool for power users, but it requires unlocking the bootloader, which irreversibly affects the security of data and the operation of some services.
