Why Xiaomi is blocking the bootloader and how to get around it
Unlocking the bootloader on Xiaomi smartphones is a must for custom firmware, root rights, or brick restoration, but the company has made it artificially difficult: the official method requires a Mi Account and 360 hours (15 days) of waiting time, which is protection against theft and unauthorized access, but for enthusiasts and developers, this restriction is a serious obstacle.
In 2026, there were workarounds that allowed you to unlock the bootloader in 1-5 minutes without waiting. Methods based on exploiting vulnerabilities in the Mi Unlock Tool authorization protocol and using alternative tools. Importantly, these methods do not violate the law, but can lead to blocking an account with frequent use. In this article, we will discuss 3 proven methods, their pros/cons and step-by-step instructions.
Warning: unlocking the bootloader resets all data on the device (including internal memory) and voids the warranty. If you're not ready, stop right now. For the rest of us, let's start with a detailed analysis.
Preparation of the device: what to do before unlocking
Before you start unlocking, make sure that all the preliminary steps are followed, and ignoring them can lead to permanent brick (irreparable firmware damage).
- π± Check the device model: methods work on the Redmi Note 10/11/12, POCO F3/F4/F5, Mi 11/12/13 and others with Qualcomm chipsets. For MediaTek (e.g. Redmi) 10C) Other tools are needed.
- π Charge the battery to at least 60%, unlocking at low charge may interrupt at a critical stage.
- π Connect the original USB-Cheap cables often don't transmit data in Fastboot mode.
- π₯οΈ Install drivers: download Mi Flash Tool and Qualcomm drivers HS-USB QDLoader 9008 (for disaster recovery).
Also mandatory:
- Enable USB debugging in Settings β About Phone β MIUI version (click 7 times, then go back to Additional β For Developers).
- Attach Mi Account to your device in Settings β Xiaomi Account (unblocking is impossible without this).
- Turn off reset protection (Settings β Password and Security β Reset Protection).
βοΈ Checking before unlocking
β οΈ Note: If you are using a locked bootloader and MIUI China ROM, Some methods may not work, and in this case, you'll need to pre-firmware on the Global/EU ROM via Fastboot.
Method 1: 360 Hours bypassing Mi Unlock Tool (2026 exploit)
This method is based on a modified version of the official Mi Unlock Tool, which bypasses latency testing.It works on most devices with MIUI 14/15 and Qualcomm Snapdragon chipsets.
Steps:
- Download the modified Mi Unlock Tool (version 6.5.224.24 or later).
- Unpack the archive and launch it. miflash_unlock.exe on behalf of the administrator.
- Sign in to your Mi Account (should be linked to your device!).
- Put the phone in Fastboot mode: turn it off, then press Volume down + Power.
- Connect the device to the PC. In the program, press Unlock.
- If a Couldnβt unlock error appears, restart the tool and try again (may take 2-3 times).
If you successfully unlock, you will see the Unlocked successfully message.The phone will automatically reboot and reset to factory settings.
What to do if the Mi Unlock Tool is 86012 error?
| Model of the device | Support for the method | Unlock time. | Risk of blocking an account |
|---|---|---|---|
| Redmi Note 11/12 Pro+ | β Yes. | 1-3 minutes | Low. |
| POCO F4/F5 | β Yes. | 2-5 minutes | Medium. |
| Xiaomi 12T/13 | β Yes (re-start required) | 5-10 minutes | High-pitched |
| Redmi 10C (MediaTek) | β No. | β | β |
π‘
If you unlock your phone and it's stuck on the MI logo, don't panic! Press Volume Up + Power for 10 seconds to force it to reboot. If that doesn't work, run the device through Fastboot using the Mi Flash Tool.
Method 2: Unlocking with EDL (Emergency Download Mode)
EDL (Emergency Boot) mode allows you to unlock the bootloader without waiting, but requires an authorized account with EDL rights. This method is suitable for devices that are not recognized in Fastboot or have corrupted firmware.
Tools required:
- π§ Mi Flash Pro 2026 with support EDL).
- π Stock firmware for your model (choose the Fastboot version).
- π Auth file for your device (can be obtained through donors or services like Telegram bots).
Step-by-step:
- Install Mi Flash Pro and Qualcomm 9008 drivers.
- Put the phone in mode. EDL: Turn off the device. Press the volume up. + Loud down and plug in. USB-Hold the buttons for 10-15 seconds until the display goes out (the device will not display the boot).

β οΈ Attention: Use EDL Without an authorized account, it can lead to a blocking IMEI (If you are not sure about the source of the auth file, you should use the first method.
Method 3: Unlock via Fastboot using ADB (for advanced)
This is a method that works for users who are familiar with ADB and Fastboot, and it relies on sending special commands that reset the wait timer, and it doesn't work on all models, but it has minimal risk of blocking the account.
Requirements:
- π» PC with installation ADB and Fastboot.
- π² Included debugging by USB unlocked OEM Unlock in the Developer Settings.
- π Original. USB-cable (important for stable connection).
Instructions:
- Connect your phone to your PC and make sure it is identified in ADB: Adb devices must display the serial number of the device.
- Reboot your device in Fastboot: adb reboot bootloader
- Check the unlock status: fastboot oem device-info If the answer has the line Device unlocked: false, you can continue.
- Send a command to reset the timer: fastboot oem unlock-go On some devices, an alternative command may be required: fastboot flashing unlock
- Confirm the unlock on the phone (if you receive a request).
If the unlock-go command is not supported, try the combination:
fastboot oem unlock
fastboot flashing unlock_criticalπ‘
The ADB/Fastboot method is the safest for an account, but it doesn't work on all devices. If the unlock-go command doesn't work, try the first or second method.
What to do after unlocking: the first steps
Once the bootloader is successfully unlocked, your device will be completely reset.
- π To apply for custom restoration (for example, TWRP) For further firmware manipulation, download the current version for your model from the official website.
- π¦ Install Magisk for root rights (optional). Use the latest stable version with GitHub.
- π Make a backup of the persist section (responsible for IMEI This will save you from accidental firmware damage.
- π§ Disable forced encryption (if you plan to use it) TWRP). For that, run a patch. disable_forceencrypt.
Warning: After unlocking the bootloader, some features may not work properly:
- Widevine L1 will be downgraded to L3 (no HD support on Netflix, Disney+).
- Some banking applications (such as SberBank Online) can block work on rooted devices.
- Updates to MIUI via OTA will stop coming (you will have to install manually).
π‘
To return Widevine L1, file the WVDFix patch through Magisk. For banking applications, use the MagiskHide Props Config module or Universal SafetyNet Fix.
Risks and how to avoid them: what you can not do after unlocking
Unlocked bootloader opens up opportunities, but also increases risks.
- Remove the persist partition without backup, which will result in loss of IMEI and inability to call.
- Firmware from a different model. Even if the chipsets match (like the Snapdragon 870), different devices have unique configurations of modules (camera, sensors).
- Using unofficial cores without compatibility testing, which can cause the processor to overheat and fail.
- Disabling dm-verity without knowing the consequences, it's protection against damage to system files, and disabling it can lead to a boot cycle.
If you are facing a problem, here is an algorithm of actions:
| Problem. | Reason. | Decision |
|---|---|---|
| Phone not turned on (black screen) | Damage to boot or dtbo partition | Swipe stock firmware through Fastboot or EDL |
| No network (IMEI invalid) | Persistent or modem partition damaged | Restore the backup persist or flash the stock modem |
| Cyclical reboot | Incompatible kernel or modules Magisk | Remove modules via TWRP or flash stock boot.img |
β οΈ Note: If after manipulation with the firmware, the phone stopped being identified in Fastboot and does not respond to buttons, do not try to flash it through Mi Flash without an auth file.
