Xiaomi Redmi Note 4X remains one of the most popular devices based on the Snapdragon 625 processor, and many owners are still looking to expand its functionality. Obtaining superuser rights or root access opens the door to deep customization of the system, removing embedded debris and installing specialized modules. However, the classic method through Fastboot and a computer with Mi Unlock often causes difficulties due to server locks or the absence of a PC at hand.
Fortunately, there are alternative ways to activate the superuser directly on the device itself, using only the capabilities of the Android operating system. In this guide, we will detail how to circumvent the limitations of MIUI and implement administrator rights using proven applications and flashing methods through recovery mode. It is important to understand that the process requires care, since interfering with system partitions always carries certain risks.
Before you take action, you need to understand the responsibility, and you take all the steps to get root rights at your own risk, because this can lead to a loss of warranty, and we'll look at two main ways: using automated utilities like KingRoot for older versions of Android, and a more advanced method with the installation of TWRP and Magisk for modern builds.
Preparation of the device and necessary conditions
The first step is to carefully prepare your Redmi Note 4X for modification. Without meeting the basic requirements, further manipulation may be impossible or lead to errors. Make sure that the battery is at least 60-70%, as a sudden power outage at a critical moment can turn the phone into a brick.
You need to activate Developer Mode. Go to Settings → About Phone and quickly click 7-10 times on MIUI Version. Once the notification "You've become a Developer" appears, go back to the settings menu and select Additional → For Developers. Here you need to enable the option Debugging over USB and, if available, Unlock OEM.
It is also critical to have a full backup of all important data, so when you unlock the bootloader or install a custom drive, all the data on the internal drive will be permanently deleted, use cloud services or copy files to an external medium if you can connect it via OTG.
- 🔋 Charge the device to at least 70% before any work begins.
- 📂 Make a full backup of contacts, photos and documents.
- 🔓 Turn on "Debugging by" USB" developer menu.
- 📶 Make sure you have a stable connection to the Wi-Fi network.
⚠️ Attention: On new versions MIUI (Global 10/11/12 and above) paragraph “Unlocking” OEM" It can be hidden or inactive without first linking your Mi Account through the official Mi Unlock app on your PC. If you can't turn this on, the method without a computer may not work.
Method One: Using KingRoot or KingoRoot Apps
For devices running on relatively older versions of Android (up to 7.0 Nougat inclusive), the use of specialized devices is often effective. APK-KingRoot and KingoRoot applications contain exploit databases that try to find a vulnerability in the system and embed a binary su file.
The process is as follows: you need to download the installation file of the selected snail from the official developer site, since there are no such applications on Google Play. After installation, run a scan of the system. If the utility finds a way to access, it will offer a "Root" or "Try to Root" button. The process takes from 1 to 5 minutes, during which the phone can reboot several times.
However, it is worth considering that on modern versions of MIUI and Android, this method does not work very much due to the enhanced kernel protection. In addition, such applications often contain advertising modules and transmit telemetry. Use this method only if other options are not available, and be sure to check the device with antivirus after the procedure.
What if KingRoot has a 95% error?
Method Two: Install TWRP Recovery through the App
A more reliable and professional way is to install the customized Team Win Recovery Project (TWRP). For Redmi Note 4X (codename mido), there are special versions that allow you to set root rights without using a computer if the bootloader is already unlocked or allows you to flash it back. If the bootloader is locked, this method without a PC is extremely difficult to apply.
There are installer apps like TWRP Installer or customized model-specific APKs that are trying to replace standard recovery. You need to find an APK that is compatible with the Snapdragon 625 architecture. Once you install the application and give it the permissions it needs, it will prompt you to flash the recovery.img image.
Once the TWRP is successfully installed, the phone needs to be rebooted to Restore mode, usually through the reboot menu in the app itself or a combination of the Up Volume + Power buttons. In the TWRP menu, you get full access to the device's file system, which is the key to further action.
- 📲 Download. APK-installer TWRP, Suitable for Snapdragon 625 chipset.
- 🛡️ Provide the application with all requested permissions to access memory.
- 🔄 Press the "Install" button. TWRP" and wait until the process is over.
- 🔌 Reboot to Recovery Mode to Check Out.
⚠️ Note: If you are trying to enter TWRP The phone is immediately loaded into the standard MIUI, So the system automatically replaced the recovery with the original one. TWRP You need to immediately after the first download drag and drop the slider "Keep Recovery Modified" or install a patch that blocks the replacement recovery.
Install Magisk to obtain Root rights
The current standard for obtaining superuser rights is Magisk. Unlike the old methods (SuperSU), Magisk is systemless, which allows you to undergo security checks in banking applications and games. ZIP-archive APK-magisk.
If you already have TWRP installed, the process is as simple as possible. Copy the Magisk.apk file (rename it Magisk.zip if you use an old TWRP, or simply select APK in newer versions) into the phone's internal memory. Go to TWRP, select Install, find the file, and confirm the installation by swipe.
Once you have completed the installation, press the Reboot System button. When you first boot, a window may appear notifying you that Magisk is doing additional setup, wait until the process is complete, then the Magisk icon will appear in the application menu, and the application settings will access the superuser rights.
☑️ Checklist of successful Magisk installation
Method comparison and version compatibility
The choice of method depends on the current version of the operating system and the status of the bootloader of your Redmi Note 4X. Automatic utilities are good for their simplicity, but have a low success rate on new firmware. The method with TWRP and Magisk requires more action, but gives full control and stability.
It is important to understand the differences between the global firmware (Global) and Chinese (China) versions. On the Chinese versions of MIUI, some system restrictions may be tougher, which will require additional steps to unlock. Also worth considering the Android version: on Android 6.0 and 7.0, methods work better than on Android 9.0 and higher.
The table below compares the main characteristics of methods for ease of choice:
| Parameter | KingRoot / KingoRoot | TWRP + Magisk | Official Unlock + Fastboot |
|---|---|---|---|
| I need a PC. | No. | Not (if the TWRP is already worth it) | Yes (required) |
| Difficulty | Low. | Medium | Tall. |
| The risk of blocking | Medium (advertising/viruses) | Low (with the correct TWRP) | Minimum |
| Supporting banks | No. | Yes (with MagiskHide setup) | Yes. |
💡
Magisk is the only solution in 2026-2026 that hides root rights from Google Pay banking applications and services.
Possible problems and ways to solve them
In the process of modifying the Xiaomi Redmi Note 4X, users often experience a cyclic reboot (bootloop).If the phone is stuck on the MI or Android logos, don't panic. Try pressing the Volume Down + Power button to log in to Fastboot, and from there reboot or try to log in to Recovery.
If TWRP doesn't see internal memory, it might be due to data encryption, so in the TWRP menu, you have to select Wipe → Format Data and type in the word yes. This action will delete all data, but it will remove the encryption, after which the file manager recovery can work correctly.
Another common problem is the lack of Internet in Recovery mode, which prevents time synchronization and signature verification. This is solved manually: in TWRP, select Settings → Time and set the correct date and time, or connect to Wi-Fi directly in the recovery menu if drivers are supported.
- 🔄 When bootloop, try resetting your settings via Recovery (Wipe Data).
- 🔒 Format Data is required to decrypt if the memory is not readable.
- 📡 Check the date and time in TWRP network-work.
- 📉 Do not interrupt the firmware process even if the screen goes out.
⚠️ Warning: If after all the manipulations, the phone stopped responding to buttons and did not enter boot modes, the boot partition may be damaged. In this case, without a computer and the Mi Flash utility to return stock firmware to mode EDL (Emergency Download is not enough.
