Getting root rights on Xiaomi smartphones has traditionally been associated with mandatory bootloader unlocking, a procedure that requires waiting 7 to 30 days, binding a Mi Account and risking losing a warranty. However, there is a lot of discussion online about alternative ways to circumvent this restriction, promising to root “without opening” the bootloader. How effective are these methods in 2026? And what pitfalls are hidden behind the promises of “light root”?
In this article, we will examine all known ways to obtain root rights to Xiaomi with a blocked bootloader, from temporary bypasses through vulnerabilities to semi-official methods using service firmware. Particular attention will be paid to models on MIUI 14/15 and Qualcomm Snapdragon/MediaTek chipsets, as well as the risks that “non-standard” solutions carry – from data loss to a complete blink of the device without the possibility of recovery via EDL.
We warn you that none of these methods are completely secure, and the manufacturer deliberately blocks these loopholes, and their use can lead to unpredictable consequences, from denial of warranty service to inability to update the firmware. If your goal is simply to remove system applications or disable ads, consider alternatives like ADB AppControl or Magisk in non-root mode.
Why Xiaomi is blocking the root without unlocking the bootloader?
Since 2018, Xiaomi has tightened its security policy by linking custom firmware installation and root rights to mandatory bootloader unlocking, a decision driven by several factors:
- 🔒 Fraud protection: A blocked bootloader makes it harder to steal data when a device is lost (an attacker will need your Mi Account to unlock it).
- 📱 Stability MIUI: System modifications often lead to failures that users blame on the “curve firmware” from the manufacturer.
- 💰 Warranty obligations: the root automatically cancels the warranty, and unlocking the bootloader serves as “confirmation” that the user was aware of the risks.
- 🔄 Update control: on devices with unlocked bootloader, Xiaomi may limit OTA-Update to avoid conflicts with the modified system.
However, in some regions (e.g. China), it takes only a few hours to unlock the bootloader, whereas for global versions (Global/EEA), the wait time can stretch for months, which has prompted enthusiasts to look for workarounds.
⚠️ Note: All of the methods described below exploit vulnerabilities in the firmware or bootloader. Xiaomi regularly closes them in new versions MIUI, So the way things work is not guaranteed. CVE-2022-2047, allowed to bypass the bootloader check on Snapdragon 865, has been corrected in MIUI 14.0.5.
Method 1: Temporary root through vulnerability in ADB (for MIUI 12–14)
One of the most common ways is to exploit a vulnerability in ADB that allows you to get a temporary root without unlocking the bootloader, which works on devices with Qualcomm chipsets (Redmi Note 9/10/11 series, POCO X3/X4) and requires:
- 📱 Smartphone on MIUI 12.5–14.0.4 (new versions can be paid for).
- 🖥️ Computer with ADB Fastboot (instructions for installation at the end of the article).
- 🔌 The debugging bridge USB Debugging included in the developer settings.
Algorithm of action:
- Connect the phone to your PC and execute the command: adb shell su -c "setenforce 0" If the command returns uid 0 - a vulnerability is present.
- Download the archive with the dirtycow utility (for example, from here) and unpack it on your phone.
- In ADB, do: adb push dirtyc0w /data/local/tmp/ adb shell chmod 777 /data/local/tmp/dirtyc0w adb shell /data/local/tmp/dirtyc0w
- After the reboot, you will have a temporary root (disappears after the phone is turned off).
This method does not provide a permanent root, and does not allow you to install Magisk or modify system files, but is only suitable for one-time actions, such as removing system applications via ADB:
adb shell pm uninstall --user 0 com.miui.analytics💡
Before using dirtycow, back up your data via adb backup – a vulnerability can damage the file system.
Method 2: Install Magisk via a patch of boot image (risky bypass)
A more advanced way is to modify the boot image (boot.img) and then run it through Fastboot without unlocking the bootloader, which works on some MediaTek devices (e.g. Redmi 9A/9C, POCO M3) due to a vulnerability in the signature verification process.
Warning: Incorrect boot.img firmware can cause a full blink of the device without the ability to recover via EDL if the bootloader is locked.The risk is particularly high on Qualcomm models!
- 📌 Step 1: Download the original firmware for your model from the Xiaomi Firmware Updater website.
- 📌 Step. 2: Extract. boot.img from the firmware archive (usually in the image folder).
- 📌 Step. 3: Install Magisk on your phone, open the app and select Install → Select and Patch a File, then point the way to boot.img.
- 📌 Step. 4: Copy the patched magisk_patched.img On PC and run it through Fastboot: fastboot flash boot magisk_patched.img fastboot reboot
If the phone is stuck on the MI logo after the reboot, the bootloader has blocked the modified image, and in this case, only:
- Firmware of the original boot.img via Fastboot.
- Or a full flashing through the Mi Flash Tool (you will need to unlock the bootloader).

Method 3: Use of service firmware (Chinese versions only)
Some Chinese versions of Xiaomi smartphones (e.g. Redmi K40, Xiaomi 11) have the ability to flash the service firmware (Engineering ROM) through Fastboot without unlocking the bootloader. These firmware are designed for testing and often contain a disabled signature verification.
List of models for which working service firmware is known:
| Model | Chipset | MIUI version | Firmware reference |
|---|---|---|---|
| Redmi K40 (alioth) | Snapdragon 870 | MIUI 12.5 Enhanced | Download |
| POCO F3 (alioth) | Snapdragon 870 | MIUI 13.0.4 | Download |
| Xiaomi 11 (venus) | Snapdragon 888 | MIUI 12.5.8 | Download |
Firmware instructions:
- Download the service firmware and unpack it.
- Turn your phone to Fastboot (Power + Vol-) mode.
- Run the command: fastboot flash boot.img fastboot flash system.img fastboot reboot
⚠️ Note: Service firmware often contains debugging code that may disrupt the communication module (e.g., will disappear). 5G They don't get a VoLTE either. OTA-Update, and returning to standard firmware will require unlocking the bootloader.

Method 4: EDL (Emergency Mode) bypass - last resort
EDL (Emergency Download Mode) is designed to restore devices with damaged firmware. On some Xiaomi models (mainly on Qualcomm), you can flash a modified boot.img through EDL without unlocking the bootloader using the Mi Flash Tool utility with signature verification disabled.
However, this method has critical shortcomings:
- 🔧 Authorized account required EDL (You can buy it on forums, but it violates Xiaomi’s rules).
- 🚨 High risk of constant breeze if firmware is selected incorrectly.
- 📵 After the firmware may disappear IMEI Baseband module (no network).
If you do decide, you will need:
- Mi Flash Tool (2018 or older version)
- File. prog_emmc_firehose.mbn For your model (you can find it on the XDA).
- Modified firmware with avb check disabled.
The firmware process through EDL:
1. Transfer the phone to EDL:
- Turn off the device.
Press Vol++ Vol- and connect to your PC (should be defined as Qualcomm HS-USB QDLoader 9008).
2.In the Mi Flash Tool, select the firmware folder and press Refresh.
3. Press Flash and wait until it is completed (don't turn off the cable!).What if the phone doesn’t turn on after EDL?
Risks and Consequences of “Unofficial” Root
Getting root rights bypassing the bootloader unlocking can cause serious problems that don't show up right away.
| Problem. | Reason. | Can we fix it? |
|---|---|---|
| Loss of loss OTA-update | Modified system conflicts with official updates | Yeah, through hand-held firmware. |
| Refusal of banking applications | SafetyNet or Play Integrity Trigger | Partially (via MagiskHide or Universal SafetyNet Fix) |
| Loss of IMEI/network | Damage to the modem partition when firmware | Sometimes (through) QCN-file) |
| Brick on the upgrade | New firmware blocks modified boot | Only through EDL or unlock |
Especially dangerous is the “hard brick” type, when the device ceases to be determined by the PC even in EDL mode. In this case, recovery is possible only with the help of soldering equipment (replacement of flash memory) or through Deep Flash Cable (special cable for forced entry into EDL).
⚠️ Note: If you have modified the boot.img and the phone stopped turning on, don't try to flash it again, this can aggravate the problem. EDL sign-checked.
💡
Any way around unlocking a bootloader is a game of roulette, and even if it works on one model, it can lead to an irreversible breeze on another.
Root alternatives: What can be done without unlocking?
If your goal is not to modify the system in depth, but to solve specific problems (delete advertising, disable system applications), consider alternatives:
- 🧹 Removing Advertising: Use ADB-Disable-services commands: Adb shell pm disable-user --user 0 com.miui.analytics adb shell pm disable-user --user 0 com.xiaomi.joyose
- 🔄 Disabling system applications: through ADB AppControl (does not require root).
- 🔒 Tracking Block: Disable Mi Account → Synchronization → Analytics.
- 📱 Customization: Use launchers like Nova Launcher or themes from the interface MIUI Themes.
For advanced users who need a root to work with TWRP or modify system files, the only reliable way is to officially unlock the bootloader.
