The official unlock process through the Mi Unlock Tool requires waiting 7-30 days, binding a Mi Account and is often accompanied by errors like βCouldnβt unlockβ or βDevice not bound.β But what if you need to urgently restore the phone after a crash, update outdated firmware or fix a critical error without waiting for unlock?
In this article, we will analyze legal and semi-legal methods of firmware Xiaomi, Redmi and POCO It is important to understand that most methods are based on exploiting vulnerabilities in the system or using service modes, so they can stop working after security updates. We are not calling for breaches of license agreements, but to show the technical capabilities available to users in 2026.
β οΈ Warning: All described methods except for official updates via Settings β About phone β System updates can lead to loss of warranty, device lock or unstable operation. Xiaomi is actively fighting workarounds, so some methods may stop working in new versions of firmware.
If your smartphone is under warranty or you are not sure of your actions, it is better to wait for the official unlock or contact the service center.
1. When firmware is possible without unlocking (and when it is not)
Not all Xiaomi devices can be flashed without unlocking the bootloader, depending on four key factors:
πΉ Firmware version and device release date: Smartphones released before 2019 (e.g. Redmi Note 5, Mi 8, POCO F1), Newer models (e.g. Redmi Note 13 Pro) often have vulnerabilities that allow them to bypass the lock.+ Xiaomi 14 is better protected β the odds are close to zero.
πΉ Firmware type. Stock. MIUI (It is almost impossible to flash without unlocking, but custom firmware (e.g. Pixel Experience or LineageOS) is sometimes installed through exploits in fastboot or EDL-mode.
πΉ Device status: If the phone loads (even with errors), chances are higher if the device is in a "brick" state (not turning on, no button response) - without unlocking or service equipment (Qualcomm) HS-USB QDLoader 9008 is not enough.
πΉ Region and version MIUI. Globally (MIUI Global and European (MIUI EU) Firmware bypass methods work less often than in Chinese (MIUI This is due to differences in security policy.
π Compatibility table of firmware methods without unlocking:
| Method | Suitable devices | Do you need a working condition? | The risk of blocking |
|---|---|---|---|
| Update via System Update | All models. | Yeah (booting) | No. |
| Firmware via fastboot with exploit | Older models (until 2020) | No (fastboot is enough) | Medium. |
| Installation through EDL (9008) | Devices on Qualcomm | No (even brick) | High-pitched |
| Using Mi Flash Pro with bypass | Selective models (list below) | Partially (fastboot needed) | High-pitched |
| Local Update with Update Package | All models (official firmware only) | Yeah (booting) | No. |
β οΈ Note: If your device is released after 2021 year-round MIUI 13/14, The probability of successful firmware without unlocking is less 10%. In this case, it is better to consider alternative options: waiting for official unlocking, contacting the service or buying a device with an already unlocked bootloader.
2. Method 1: Update via local packet (official risk-free method)
The safest and most legitimate way to update your firmware without unlocking it is to use a local service pack, which works on all Xiaomi models, but has limitations:
- You can install only official firmware (no custom recovers or modified versions).
- The firmware version should be newer than the current one (rollback to the old version is blocked).
- The device must be loaded into the system (not suitable for "bricks").
πΉ Step-by-step instruction:
1οΈβ£ Download the correct firmware from the official website:
- π For global devices: MIUI Global Download
- π¨π³ For Chinese devices: MIUI China Download
- πͺπΊ For Europeans (EEA): MIUI EU Download
β οΈ Important: Choose firmware strictly for your model! Installing firmware from another model will lead to a complete loss of performance (hard brick).
2οΈβ£ Transfer the firmware file (.zip format) to the root directory of the phone's internal memory: miui_[Model [VERSION].zip (e.g, miui_VAYUGlobal_V14.0.3.0.TJWMIXM_213a123456_12.0.zip).
3οΈβ£ Run the update:
- Go to Settings β About the phone β System update.
- Click on the three dots in the upper right corner β Select the service pack.
- Specify the downloaded file and confirm the installation.
4οΈβ£ Wait for the end (5-15 minutes). The phone will reboot automatically.

If the update hung during the verification phase, try renaming the firmware file to update.zip repeat.
β Advantages of the method:
- π Completely safe (does not violate warranty).
- π It works even on new models.
- π± Doesn't require a computer.
β Limitations:
- π« There is no way to downgrade the version. MIUI.
- π You can't install custom firmware.
- π οΈ It wonβt help if the phone doesnβt turn on.
Method 2: Firmware through fastboot with exploit (for older models)
This method is suitable for devices released before 2020 It's based on vulnerabilities in fastboot mode, and it allows you to flash a full image of the firmware. ROM) without unlocking the bootloader, but requires a computer with drivers and tools installed ADB/Fastboot.
πΉ What devices are supported?
List of models for which working exploits are known (as of June 2026):
- π± Redmi Note 7/7 Pro (lavender/violet)
- π± Redmi Note 8/8 Pro (ginkgo/begonia)
- π± POCO F1 (beryllium)
- π± Mi 8/8 SE/8 Lite (dipper/sirius/platina)
- π± Mi 9/9 SE/9T (cepheus/grus/davinci)
πΉ What's the matter:
- π₯οΈ Windows computer 10/11 Linux.
- π Cable USB Type-C (original or high-quality).
- π¦ Firmware in fastboot format ROM (You can download the Xiaomi Firmware Updater).
- π οΈ Utilities: ADB & Fastboot, Python 3.x (exploit).
πΉ Step-by-step instructions (on the example of Redmi Note 7):
1οΈβ£ Install drivers and tools:
2οΈβ£ Connect your phone in fastboot mode:
- Turn off the device.
- Press the power button. + volume-cutting button for 10 seconds.
- Connect to your computer β it should be defined as Android Fastboot.
3οΈβ£ Check the connection:
Open the command line (Win + R β cmd) and do:
fastboot devicesIf the device is displayed (e.g, 1234567890abcdef fastboot - can continue.
4οΈβ£ Use the exploit to bypass the lock:
For the Redmi Note 7 (Lavender) is a good exploit fastboot_oem_edit. Download it from GitHub and follow the instructions:
python fastboot_oem_edit.py unlock
fastboot flash [section] [firmware file]5οΈβ£ Firmware via Mi Flash Tool:
- Download the Mi Flash Tool.
- Unpack fastboot ROM in a folder without spaces (for example, C:\ROM\lavender_global_images_...).
- In the Mi Flash Tool, select the firmware folder and click Refresh β Flash.
β οΈ Note: If a "flash not allowed" or "device locked" error appears during firmware, the exploit did not work. Try another method or check whether the vulnerability is relevant to your model.

π‘
This method only works on older devices with a vulnerable bootloader, and for newer models (Redmi Note 12, Xiaomi 13 and later), it is useless due to closed vulnerabilities in fastboot.
Method 3: Firmware through EDL (9008) β extreme case for bricks"
Regime. EDL (Emergency Download Mode is a service mode for firmware devices on Qualcomm chips, which allows you to restore the phone even in a hard brick state (when neither fastboot nor recavers work:
- π Authorized Xiaomi account (for new models).
- π» Special software (Mi Flash Pro, QFil or other software) EDL Tool).
- π Cable with support EDL (Sometimes a soldering iron is required to close contacts).
πΉ How to get in mode EDL?
There are two ways:
- Software: via adb reboot edl (works if the phone is turned on and there is root).
- Hardware: Close contacts on the board (requires disassembly of the device). For most models, these are contacts TEST POINT near-battery.
πΉ Step-by-step (for Redmi Note 10 Pro):
1οΈβ£ Download the necessary files:
2οΈβ£ Put the phone in mode. EDL:
- Turn off the device.
- Connect to your computer by holding the volume buttons (or lock them). TEST POINT).
- The device manager should appear Qualcomm HS-USB QDLoader 9008.
3οΈβ£ Firmware through Mi Flash Pro:
- Run Mi Flash Pro and select the firmware file.
- Press Select and specify the port. COM, plugged.
- Press Flash and wait until it is completed (10-20 minutes).
β οΈ Note: On new models (Xiaomi) 12/13, Redmi Note 11/12) Xiaomi is blocking the firmware through EDL You don't have to log in "SLA Auth Error or Firehose not allowed means you will need an official service center account or a charge-based bypass. EDL Authorized Box (cost) ~$50β$100).

Method 4: Using Mi Flash Pro with a check-bypass (for sample models)
Some Xiaomi models (mostly) 2019β2020 This method is not universal, but it works for Qualcomm Snapdragon chips, and allows you to flash official firmware through Mi Flash Pro without unlocking the bootloader if you use a modified version of the tool or special scripts. 6xx/7xx/8xx.
πΉ List of supported models (according to community data) XDA):
- π± Redmi K20 / Mi 9T (davinci)
- π± Redmi Note 8 Pro (begonia) - only with a patch for the MTK.
- π± POCO X3 NFC (surya)
- π± Mi 10 / Mi 10 Pro (umi/cmi) β partial support.
πΉ What's the matter:
- π¦ Firmware in fastboot format ROM (official only!).
- π οΈ Mi Flash Pro (modified version).
- π§ Script to circumvent verification (e.g, bypass_anti_rollback.py).
πΉ Instructions (by example) POCO X3 NFC):

Method 5: Installation of custom recaveri (TWRP) Unlocked (limited)
Installation TWRP (Team Win Recovery Project, which is only available on older devices with fastboot vulnerabilities or through kernel exploits without unlocking the bootloader, allows you to flash custom firmware, but has serious limitations:
- π It only works on devices until 2020 (Redmi Note 7, POCO F1, Mi A2 etc.).
πΉ Step-by-step (for Redmi Note 7):

β οΈ Note: On new devices (Redmi Note 10 and later) installation TWRP Without unlocking the bootloader will lead to locking (the error "Orange State" or "Device corrupted"). You can restore the workflow only through the Mi Flash Tool with authorization.
7 Risks and Consequences of Firmware Without Unlocking
Xiaomiβs firmware without officially unlocking the bootloader is a security bypass that can lead to serious problems.
π΄ Xiaomi considers any interference with the bootloader to be a violation of the warranty. Even if you restore the stock firmware, the service center can detect traces of changes through the fastboot log.
π΄ On newer models (Redmi Note 11 and later), a failed firmware attempt can result in a permanent lock ("This device is locked") that can only be fixed at the service center.
π΄ Firmware installed to bypass security can be faulty:
- π΅ Network problems (no signal, no signal) 5G).
- π Fast battery discharge.
- π΅ The speakers or microphone are not working.
- π± Accidental reboots.
π΄ Update issues, after unofficial firmware OTA-Updates may not be installed or may cause failures.
π΄ Data leakage: Some workarounds require the use of informal tools that may contain malicious code.
