Modern Xiaomi smartphone users often face the limitations of the standard MIUI shell, which does not allow you to fully unleash the potential of the device. Obtaining the rights of the Root superuser opens up access to system files, allowing you to delete preinstalled software, modify the kernel and install powerful modules through Magisk. However, the process of implementing administrator rights on the Redmi Note 7 requires careful and strict adherence to the algorithm of actions.
Installing Magisk is not just a single program, but a complex procedure that involves unlocking the boot boot boot boot and modifying the boot system partition. Errors at any stage can lead to data loss or even turn the device into a “brick.” In this article, we will detail each step necessary to successfully install your smartphone.
Before you take action, you need to understand the risks. Any interference with the code of the phone removes the official warranty and carries a potential threat to the stability of the system.However, with the right approach and use of proven tools, you can safely get full control of your Redmi Note 7.
Preparation of the device and assembly of necessary tools
The first step is to carefully prepare the workplace and software, and you'll need a computer running Windows, macOS or Linux, and a good computer. USB-A cable that can transmit data, not just charge the device, but you need to install the latest version of the drivers on your smartphone. ADB Fastboot, which is the bridge between the PC and the phone.
Just as important is to back up all the data, the process of unlocking the bootloader, which is a prerequisite for installing Magisk, involves completely resetting the device to factory settings, and all photos, contacts and apps will be deleted without the ability to recover through standard means.
To work, you will need to download the latest version of the Magisk app in APK format from the official GitHub repository. You will also need an exact copy of the firmware (boot.img image) corresponding to the version of MIUI installed on your Redmi Note 7 right now.
☑️ Firmware readiness check
Make sure that the device is debugging USB. To do this, go to Settings → About Phone and click on the build number seven times to activate the developer menu. Then, in the Developer section that appears, activate the USB Debugging slider.
Unlock Bootloader on Redmi Note 7
Xiaomi has implemented strict protection against unauthorized software changes, so a standard installation of Magisk is impossible without an unlocked Bootloader.This process requires linking a Mi Account to the device and waiting for a certain time, which can be from 7 to 168 hours.
Once you have permission from the Mi Unlock app on your PC, you need to turn your smartphone into Fastboot mode. To do this, turn off your phone and press the Down volume and power buttons simultaneously until the image of a rabbit repairing an android appears on the screen. Connect the device to your computer and press the Unlock button in the utility.
⚠️ Note: Once the bootloader is unlocked, all data on the internal drive will be permanently deleted, and some banking applications and Google Pay may stop working as standard, requiring additional security settings.
The unlocking process takes only a few minutes, but it is critical for further manipulation. If the bootloader status has changed to Unlocked, you can proceed to the next step, otherwise the system will give an error, and the procedure will have to be repeated, checking the Internet connection and the status of the acca-unt.
It is worth noting that re-locking the bootloader on an already modified system can cause the device to fail. So if you plan to use Magisk, leave the bootloader open, which will allow you to return to clean firmware at any time via Recovery or Fastboot mode.
Removing and patching the boot.img image
The most important step is to modify the boot image, so you need to find the exact version of the firmware for your region (Global, China, Russia) that is installed on your phone, and you need to extract the boot.img file from the firmware archive and transfer it to the internal memory of the smartphone.
Install the downloaded earlier APK-Magisk file and launch the application. In the main menu, find the "Install" section and click "Select file." In the file manager, specify the path to the copied one. boot.img. The application will analyze the file and suggest starting the patching process.
After clicking the Start button, Magisk will make the necessary changes to the kernel code, adding its scripts to obtain root rights. Upon completion of the process, a new file with a name like the Download folder will appear in the Download folder. magisk_patched_[random].This file must be copied back to the computer.
What if Magisk doesn’t see boot.img?
It is important not to interrupt the patching process and wait for the message "It's ready." If the process fails, the file will be corrupted, and its use in the firmware can lead to bootloop-y. In this case, the extraction and patching procedure must be repeated again.
Firmware of modified image via Fastboot
To write the modified image to the memory of the device again require Fastboot mode. Connect Redmi Note 7 To PC, open the command line or terminal in the tool folder ADB/Fastboot. Make sure your computer sees the device by entering the command fastboot devices.
The basic command for firmware is as follows:
fastboot flash boot magisk_patched_[random].imgWhere? magisk_patched_[random].Img should be the exact name of your file. After successfully executing a command that takes a few seconds, you need to restart the device. 10-15 seconds.
| Fastboot Team | Description of action | The result |
|---|---|---|
| fastboot devices | Connection check | Display of the serial number |
| fastboot flash boot... | Record the image in the Boot section | Successful recording |
| fastboot reboot | Rebooting the device | Android launch |
| fastboot getvar all | Receipt of information | Details on the status of the lock |
The first download after the firmware can take longer than usual, and it's normal behavior, because the system checks the integrity of the changed files, and if the phone boots up and you see the desktop, then the first step is successful.
Installation check and basic Magisk setup
Once you boot, look for the Magisk icon in the application menu. When you first start up, the application may request additional permission and restart to complete the installation.
The main application window opposite the "Magisk" should have "Installed" status with version on it, and if you see the version and code number, root rights are active, so you can install modules that allow you to change system fonts, audio drivers, or hide the fact that superuser rights are in place.
💡
Use MagiskHide (or Zygisk in newer versions) to hide root rights from banking apps and anti-cheat games, and without that, they may not work.
You can use specialized tools like Root Checker to verify that you have superuser rights and send a message, and now your Redmi Note 7 has enhanced functionality.
Problem Solving and Diagnosing Errors
Often, users are faced with a situation where the phone goes into an endless restart (bootloop). If this happened after the boot.img firmware, most likely, the image was damaged or does not correspond to the firmware version, in which case you need to return to Fastboot mode and flash the original, unmodified boot.img.
Another common problem is module failure, often due to conflicting versions of Magisk and Android itself. Always back up through built-in functionality or TWRP before installing heavy modules, if installed.
⚠️ Warning: Never remove the Magisk app through the standard Application Manager if you want to keep root rights. Use the Full Delete feature inside the app itself to remove it completely or scrub through the original image.
If your computer stops seeing your phone in Fastboot mode, try replacing it. USB-cable or switch port on the motherboard (preferably use ports) USB 2.0 at the back of the system unit.You may also need to reinstall Qualcomm or Xiaomi drivers.
💡
The main reason for the installation failure was the use of boot.img from another firmware version, so always check the MIUI build numbers before starting work.
