How to flash Xiaomi without unlocking the bootloader: all working ways in 2026

Introduction: Why Unlocking a bootloader Is Not Always Necessary

Xiaomi’s smartphone firmware has traditionally been associated with the need to unlock the bootloader, which requires waiting 7 to 30 days for approval from the company, linking a Mi Account account and risking losing the warranty. However, there are legal and semi-official methods to upgrade or reflash the device without unlocking, which work even on new models with HyperOS.

In this article, we’ll break down 4 proven ways to run Xiaomi firmware without unlocking the bootloader, from standard OTA updates to hidden Fastboot modes and tools like the Mi Flash Tool with workarounds. Importantly, not all methods are suitable for downgrading or installing custom firmware, which we’ll talk about as well.

Before you start, check:

• 📱 Device model (e.g. Redmi Note 12 Pro)+ 5G or POCO F5) — The methods are different for the Redmi series, POCO Xiaomi.
• 🔄 Current version MIUI/HyperOS (In Settings → The phone).
• 🔋 Battery charge (minimum 60% - when the process is interrupted, the phone can turn into a brick»).

Method 1: Official OTA-Update through the Three Points»

The safest method is to use a hidden menu. OTA-Updates that allow you to manually download and install firmware without unlocking.This method works on most Xiaomi devices with a new device. MIUI 12-15 and HyperOS, but not suitable for downgrade or firmware installation from other regions.

Instructions:

1. Download the full OTA (.zip file) package for your model from the official Xiaomi website or resources like Xiaomi Firmware Updater.
2. Rename the file to update.zip and move it to the root folder of the phone’s internal memory (not to folders like Download).
3. Open the Updater app, click on the three dots in the upper right corner and select Select the firmware file.
4. Specify the path to update.zip and confirm installation. The phone will reboot and update automatically.

Limitations of the method:

• ❌ It doesn't work for the transition from MIUI HyperOS (requires full firmware via Fastboot).
• ❌ You cannot install firmware for another region (for example, from Global to China).
• ✅ Suitable for correcting bugs after a bad one OTA-update.

💡

If the Three Dots menu doesn’t have a file selection option, try renaming it. update.zip into miui_OTA_name.zip, where the name is the code of your model, for example, miui_VIVALDIGlobal_OS1.0.2.0.UMBMIXM_20231212.0000.00_13.0_global.zip).

Method 2: Fastboot firmware without unlocking (EDL method)

Emergency Download Mode (EDL) allows you to flash a Xiaomi phone even with a locked bootloader, but requires a special cable (EDL-cable) or short circuit test contacts on the board, a method often used in service centers and suitable for restoring bricks or forced installation of stock firmware.

Step-by-step:

1. Download the Fastboot firmware (.tgz or.zip file) from Xiaomi or Xiaomi Firmware Updater. Unpack it into a folder without Cyrillic characters.
2. Install Qualcomm HS-USB QDLoader 9008 (for Snapdragon processors) or MediaTek Preloader (for Helio/Dimensity chips).
3. Put the phone in mode. EDL: 🔧 For Snapdragon: Click Loudness+ + Loudness− Connect the cable to the PC (you need EDL-cable or closing test points). 🔧 For MediaTek: use the adb reboot edl command (if you have a ADB included).

⚠️ Attention: Firmware through EDL Without an authorized Mi Authorized Account, you may be blocked. IMEI on new models (e.g. Xiaomi) 13T, Redmi Note 12 Turbo Devices 2023-2026 require official access to the EDL, Which is available only at service centers.

Method 3: Local updates via Recovery (for MIUI)

If your Xiaomi is running MIUI (not HyperOS), you can use a local update via Recovery.This method does not require unlocking the bootloader, but is only suitable for installing official firmware in the same region.

Algorithm of action:

1. Download the full firmware (not downloaded) OTA!) It's.zip for your model, like the Redmi Note. 11 Pro+ 5G It could be a file. veux_global_images_V13.0.6.0.SKCMIXM_20221010.0000.00_12.0_global.zip.
2. Rename the file to update.zip and place it in the root of internal memory.
3. Turn off the phone and press Volume++ Power to enter Recovery.
4. Select the language (if required), then go to Install update.zip to System.
5. Confirm the installation and wait until the completion (the process will take 5-10 minutes).

⚠️ Note: HyperOS doesn't use this method, instead of Recovery, it uses a Fastboot with a mandatory unlock. It also doesn't allow installing firmware for other regions (e.g. China). ROM Global, as this will result in the network being blocked.

What if Recovery doesn’t see the update.zip file?

• 🔄 Check the file name (it should be exactly the same). update.zip, numerically or postfixed).
• 📁 Put the file in the root of memory, not in the Download folder.
• 🔧 Try another firmware file (sometimes Recovery doesn't accept it) OTA-packet).

Method 4: Bypassing the unlock through vulnerabilities (older models only)

On Xiaomi devices until 2021 release (for example, Redmi Note 9 Pro, POCO X3 NFC), there are exploits that allow you to temporarily bypass the bootloader lock. One of the most famous is the DirtyCOW vulnerability, which allows you to write data to protected partitions without unlocking.

How it works:

1. Install DirtyCOW Exploit on your phone (available on 4PDA or XDA Developers).
2. Download a modified boot.img for your model (for example, with the Magisk patch for root rights).
3. Run the exploit and specify the path to boot.img. The application will temporarily access the sections and record the image.
4. Restart your phone to Fastboot and run the full firmware through the Mi Flash Tool.

⚠️ Note: This method does not work on HyperOS devices and newer versions MIUI 14+, The DirtyCOW vulnerability has been closed, and it can lead to data loss or Mi Account blocking if misused.

Risks and consequences of firmware without unlocking

Xiaomi firmware without unlocking the bootloader is always a compromise between convenience and security.

• 🚨 Lockdown IMEI (starting MIUI 13 and HyperOS: when unofficial firmware is EDL Fastboot without authorization.
• 🔒 Warranty loss: Even if the bootloader remains locked, firmware traces remain in the logs (efuse).
• 📵 Network problems: when installing firmware from another region (e.g. China) ROM Global device).
• 🔄 Cyclical reboot: if the firmware is incompatible with the phone’s hardware revision.

How do you minimize the risks?

• 📌 Use only official firmware from the Xiaomi site (not custom LineageOS or Pixel Experience).
• 📌 Check compatibility with model code (e.g. veux for Redmi Note 11 Pro)+ 5G).
• 📌 Do backup through Mi Cloud or TWRP (if the loader is already unlocked).

💡

Firmware without unlocking the bootloader is possible, but is only suitable for official updates or restore stock software. For custom firmware, root rights or downgrade, unlocking is mandatory.

Frequent mistakes and their solutions

Even when following instructions, users encounter errors.

If after firmware the phone hangs on the logo or does not load, try:

1. Reset your settings via Recovery (Wipe Data).
2. Repeat the firmware using clean all in the Mi Flash Tool.
3. Check the integrity of the firmware file (compare) MD5-hash).
