Xiaomi bootloader recovery: 5 proven ways (2026)

The bootloader is the first software component that starts when you turn on a Xiaomi smartphone, and it is responsible for initializing the hardware and handing over control to the operating system. If the bootloader is damaged or removed, the device stops booting, getting stuck on the Mi or Redmi logo, or does not respond to the power button at all, a problem that often occurs after a failed firmware, unlocking the bootloader through the Fastboot, or experimenting with custom recapers (TWRP).

Xiaomi bootloader can be restored in a number of ways, from auto-restore via the Mi Flash Tool to manually stitch through the Fastboot or EDL- mode. It is important to understand that the procedure requires strict compliance with instructions: an error at any stage can turn a smartphone into a “brick.” In this article, we will discuss 5 working methods relevant to the 2018-2026 models, including the Redmi Note 12, POCO X5, Mi 11 and others.

Causes of damage to Xiaomi bootloader

The bootloader can fail for several reasons, and understanding them will help you choose the right recovery method.

• 🔧 Failed firmware via Fastboot. If there is a failure during firmware running through the Mi Flash Tool (disabling USB, battery drain, error in firmware files), the bootloader may be damaged or erased.
• 🔓 Unlock bootloader: Officially unlocking through the Mi Unlock Tool sometimes causes crashes, especially if you interrupt the process or use an incompatible version of the utility.
• 📱 Install custom Recovery (TWRP) Incorrect installation or version conflict TWRP may compromise the integrity of the bootloader.
• ⚡ Hardware failure: A sudden power outage during system upgrades or physical memory damage (eMMC/UF) also leads to bootloader problems.
• 🔄 Retrace to old firmware: Trying to flash an older version MIUI than the one installed is often blocked by Anti-Rollback protection, which can damage the bootloader.

Symptoms of a damaged bootloader range from a complete lack of reaction to the power button to a cyclic restloop or errors like Fastboot mode or EDL mode.

• 🚫 Not at all (black screen, no vibration).
• 🔄 Stuck on the Mi/Redmi/POCO logo and rebooted.
• 💻 Only comes in Fastboot or EDL (a screen with a rabbit and the inscription Qualcomm HS-USB QDLoader 9008).

So the problem is with the loader.

⚠️ Warning: If the smartphone is not detected by the computer even in Fastboot/EDL mode, the problem may be in the hardware (damaged USB- port, power controller or memory), in which case diagnostics are required at the service center.

Preparation for loader recovery

Before you start your recovery, you need to prepare tools and files to minimize the risk of errors and speed up the process.

• 🖥️ Windows PC 7/10/11 (for Mi Flash Tool and QFil). MacOS and Linux are not supported by official Xiaomi utilities.
• 🔌 Original USB- cable (preferably the one that came with it) cheap cables can cause data transmission errors.
• 🔋 At least 50% charge. If the battery is dead, plug your smartphone into charging for 10 to 15 minutes before starting the procedure.
• 📁 Firmware for your model. Download it from the official Xiaomi website or from the XDA Developers forum (for custom firmware).
• 🛠️ Drivers: Qualcomm HS-USB QDLoader 9008 (for EDL) and Mi USB Driver (for Fastboot).

Utilities will also be required:

Warning: If you are restoring the bootloader to models with a MediaTek processor (such as Redmi 9A or POCO C3), instead of QFil, you will need the SP Flash Tool.

Method 1: Recovery via Fastboot (Mi Flash Tool)

This is the most reliable method for most Xiaomi devices if the smartphone is determined in Fastboot mode. Suitable for models on Qualcomm Snapdragon and some MediaTek.

Steps:

1. Download the firmware for your model in.tgz or.zip format (e.g. tissot_global_images_V12.0.3.0.PDHMIXM_20210315.0000.00_10.0_global).
2. Unclick it into a folder without Cyrillic characters (e.g., C:\Mi\rom).
3. Install Mi USB Driver drivers and restart your computer.
4. Launch the Mi Flash Tool, press Select and specify the path to the firmware folder.
5. Connect the smartphone off to your computer, holding Volume Down + Power to log into Fastboot.
6. In the Mi Flash Tool, press Refresh – the device must be determined.
7. Select firmware mode: Clean all (deletes all data); Clean all and lock (clean + lock bootloader (recommended for recovery); Save user data (does not always work with a damaged bootloader).

Flash

If the Mi Flash Tool gives an error critical partition flashing is not allowed, then the bootloader is locked. It must be unlocked through the Mi Unlock Tool (see Method 3).

Download the right firmware for your model

Install Mi USB Driver Drivers

Unclose the firmware in a folder without Cyrillic

Charge your phone at least 50%

Connect the original USB-cable-->

Method 2: Firmware in EDL- Mode (Qualcomm)

If the smartphone doesn’t load even in Fastboot, but is defined as a Qualcomm HS-USB QDLoader 9008, it can be restored via EDL (Emergency Download Mode).This method works for devices running Qualcomm Snapdragon chips (e.g., Redmi Note 10 Pro, POCO X3 Pro).

Instructions:

1. Download firmware in.mbn or.elf format (for example, for QFil). Official firmware from Xiaomi for EDL is rarely posted publicly, so you may need to search XDA or forums.
2. Install the Qualcomm HS-USB QDLoader 9008 driver (can be found in the archive with QFil).
3. Start QFil, select Flat Build under Select Build Type.
4. In the Programmer Path field, specify the path to the prog_emmc_firehose.mbn file (it should be in the firmware archive).
5. In Load XML, download rawprogram0.xml and patch0.xml (sequential).
6. Connect the phone to your computer by holding Volume up + Volume down (or use a testpoint if the device is not detected).
7. Press Download and wait until it is completed (the process can take up to 15 minutes).

If QFil is a Sahara Communication Failed or Firehose Config Failed error, try:

• 🔌 Use the other USB-port (preferably) USB 2.0 on the back of the PC).
• 🔄 Reinstall the QDLoader 9008 driver manually through Device Manager.
• 📁 Replace the prog_emmc_firehose.mbn and rawprogram0.xml files with those that are relevant to your model.

⚠️ Warning: Firmware running through EDL without an auth file can result in a hard brick device lock. Newer models (Snapdragon 8 Gen 1/2) require an authorized Xiaomi account or help from a service center.

Method 3: Unlock the bootloader through the Mi Unlock Tool

If the bootloader is locked and you are trying to flash the device, the Mi Flash Tool will give an error, in which case you will need to officially unlock through the Mi Unlock Tool. Note: this process erases all data on the device and requires an association of the Mi Account.

Step-by-step:

1. Download Mi Unlock Tool from the official website and install it on your computer.
2. Sign in to your Mi Account (it should be linked to your device in advance!).
3. Transfer your smartphone to Fastboot (Loudness down + Power).
4. Connect the device to your computer and start the Mi Unlock Tool.
5. Press Unlock and wait until it is completed (usually takes 1-3 minutes).
6. After unlocking, repeat the firmware through the Mi Flash Tool (choose Clean all mode).

Important nuances:

• 🔐 The Mi Account must be older than 30 days, otherwise unlocking will not be available.
• 📱 The device must be linked to the account in the settings (Settings → Mi Account → Devices).
• 🔄 If unlocking fails, try connecting to another Internet connection (sometimes the locks are linked to IP).

⚠️ Warning: Once the bootloader is unlocked, some features may not work properly (e.g., Widevine L1 to view HD- content on Netflix or Disney+ will be downgraded to L3).

Method 4: Recovery via TWRP (for unlocked devices)

If your Xiaomi already has a custom TWRP recavator installed and the bootloader is unlocked, you can try to restore it through the firmware of individual partitions. This method is suitable for advanced users.

Instructions:

1. Download the firmware for your model in.zip format (for example, with XDA).
2. Move the firmware file to the SD- card or to the device memory (if available).
3. Load to TWRP (Loudness Up + Nutrition).
4. Select Install and specify the path to the firmware file.
5. Before you run your firmware, run Wipe → Advanced Wipe and mark Dalvik / ART Cache System Data (if user files are not important)

Sweep through the firmware and restart the device.

If the device loads after firmware but gets stuck on the logo, try TWRP to do:

adb shell


dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc

This command clears the misc partition, which may contain incorrect system state data.

💡

If your phone doesn't turn on after you've run through TWRP, try flashing only the boot section separately. To do this, select Install → Install Image in TWRP and specify boot.img from the firmware archive.

Method 5: Hardware recovery (testpoint and programmers)

If the software methods didn’t help, and the smartphone is not defined in either Fastboot or EDL, then hardware recovery remains, which is an extreme measure that requires disassembling the device and working with testpoints or programmers (UFi Box, EasyJTAG).

Where this may be necessary:

• 🔌 The device does not respond to the power button and is not determined by a computer.
• 🔧 The firmware through EDL ends with the Sahara Fail or Firehose Fail error.
• 💾 Memory damage (eMMC/UF) that blocks partition access.

The process includes:

1. Disassembly of the smartphone and search for test points (for forced entry into the EDL).
2. Connect to the programmer to flash memory at a low level.
3. Restoration of the partition table and firmware of the bootloader manually.

This method requires special equipment and skills, and if you are not confident in your abilities, you should contact a service center, the cost of recovery through a programmer varies from 1,500 to 5 000 rubles depending on the model.

💡

Hardware recovery is the only way to bring a damaged memory (eMMC) smartphone back to life, but it requires professional hardware and can cost more than the device itself.
