Xiaomi firmware via QFil in mode EDL: Complete guidance with mistakes and decisions

Firmware Xiaomi smartphones through Qualcomm Flash Image Loader (QFil) is one of the most reliable ways to restore a device when standard methods (via Fastboot or Recovery) do not work. This method is used when the phone has turned into a "brick" after a failed upgrade, resetting settings or experimenting with custom firmware. EDL (Emergency Download Mode allows you to directly interact with the Qualcomm processor, bypassing a damaged operating system.

However, the firmware process through QFil requires care: wrong actions can permanently bring the device down. In this article, we will discuss the unique nuances of the firmware of Xiaomi models from 2020-2026, including installing drivers, choosing the right firmware files, and solving typical errors like Sahara Communication Failed or Firehose mismatch.

What is QFil and When to Use It

QFil (Qualcomm Flash Image Loader) is Qualcomm's official firmware utility for devices based on their processors. Unlike the Mi Flash Tool, which runs through Fastboot, QFil communicates with the phone at a lower level through a port. EDL. It allows for that:

• 🔄 Restore the “bricks” after unsuccessful firmware;
• 📱 Devices with a damaged bootloader (bootloop);
• 🔧 Bypass the Mi Account lock (in some cases);

Officially, the utility is distributed through the Qualcomm website, but for ordinary users it is available on the forums:

• 🔗 XDA Developers (search for QFil latest version);
• 🔗 4PDA (The "Firmware" section for your model);
• 🔗 Xiaomi Firmware Updater (tool archive).

2.Selection of firmware for QFil

For firmware through EDL You need a special file. prog_emmc_firehose.mbn (Or.elf for old models. You can find it:

• 📂 In the stock firmware archive (look for the image or firmware folder);
• 🔍 In thematic forums (for example, in the topics about your model on the subject). 4PDA);
• 🛠️ In packages for unlocking the bootloader (for example, Mi Unlock Tool).

Important: The firehose file must match the model and the version of the processor. For example, for the Redmi Note 10 Pro (Snapdragon). 732G) Poco's firehose is not suitable. X3 (Snapdragon 732G revision).

Installation of drivers

Without the Qualcomm driver HS-USB QDLoader 9008 Windows does not recognize the phone in mode EDL. Download the driver from one of the sources:

• 🔗 GitHub (bkerler/edl);
• 🔗 XDA (universal driver).

Installation:

1. Connect the phone to the PC switched off;
2. Hold the volume.+ and Loudness− simultaneously (to enter the EDL);
3. In Device Manager, find an unknown device (QHUSB_BULK);

⚠️ Attention: On Windows 10/11 You may need to disable driver signature verification. To do this, restart your PC in Debugging Mode (click on) F7 When downloading, or use the command in CMD on behalf of the administrator: bcdedit /set Testsigning on After installing the driver, return the settings back: bcdedit /set testsigning off

Step-by-step: how to flash Xiaomi through QFil

When you're done, you can start the firmware. Follow the instructions carefully, because failure at any stage can lead to irreversible consequences.

Step 1: Enter EDL mode

There are two ways to get Xiaomi into the mode. EDL:

1. Hardware method (for working devices): Turn off the phone; Close Volume+ and Loudness−; Connect. USB-Cable to PC; Hold the buttons for 10-15 seconds until Qualcomm appears in Device Manager HS-USB QDLoader 9008.
2. Programming method (through ADB): adb reboot edl only works if the phone is turned on and there is access to the phone ADB.

If the phone doesn't respond, you may need a testpoint, which is a risky procedure, and you should contact a service center.

Step 2: Starting QFil and setting up

Open QFil on behalf of the administrator.

2. In Select Programmer, specify the path to the file. prog_emmc_firehose.mbn;
3. Press Load. XML and select the files rawprogram0.xml and patch0.xml (They should be in the firmware archive).

If there are no.xml files, use the Load option. XML → Browse and manually specify the path to the firmware folder. QFil automatically selects the desired files.

Step 3: Starting the firmware

When all files are uploaded:

1. Press Download;
2. Wait until the utility recognizes the device (Connected to port will appear in the log: COMX);
3. Wait until the process is completed (usually 5-15 minutes).

If the phone doesn’t turn on or is stuck on the logo, repeat the firmware with another version of firehose or check the integrity of the firmware files.

💡

The firmware through QFil erases all the data on the device. If the phone has any response to the connection, first try to save the data through the device. ADB or specialized utilities.

Common mistakes and their solution

Even with the correct instructions, errors can occur, and here are the most common ones and how to correct them:

If QFil is not reporting a Sahara Communication Failed error, try:

1. Disable the antivirus (it can block the utility);
2. Use the other USB-port USB 2.0);
3. Reinstall the driver manually through Device Manager.
