• 🔄 Restore firmware if the boot or system partition is damaged;
• 🔧 Bypass locks (for example, if you forget a pattern lock or password);
• 🛠️ Modified firmware (e.g. Global) ROM Chinese version);
• 📱 Restore. IMEI or serial number after discharge.

Difference EDL Fastboot: In Fastboot, the phone bootloader is already partially initialized, while EDL It works at the processor level, ignoring damaged memory partitions, making it the only way out when you have a soft brick (for example, when the phone vibrates when you turn on, but the screen is black).

⚠️ Attention: Activation EDL On current Xiaomi models (released after 2021) it can lock the device through Mi Account server verification, which means that after firmware, the phone will require entering a login and password from the account that was tied before the reset.

Official method: through an authorized service center

The safest, but also the most expensive, method is to contact the official Xiaomi service, employees use special equipment (Mi Authorized Tool) and have access to server keys to unlock. EDL. Advantages:

• 🔐 Guarantee of data retention (if possible);
• 📄 Official guarantee for the work performed;
• 🛡️ There is no risk of blocking the account (unlike the “handicraft” methods).

Disadvantages: the cost of the service can reach 30-50% of the price of a new phone, and the waiting time is up to 2 weeks. EDL: Some are limited to just replacing the fee.

If you decide to use this method, check with the service center in advance if they work with your model. 12T or POCO F4 You may need to send the device to a regional center.

Informal methods of inclusion EDL

If the service is not available, you can try to activate it. EDL There are three main ways:

1. Through a button combination (works on older models until 2019);
2. With the help of testpoint (requires disassembly of the phone);
3. Through ADB/Fastboot (if the phone still turns on).

Let's look at each one in detail.

1. button combination (for older models)

On Xiaomi devices until 2019 (e.g. Redmi Note 5, Mi) A1, Mi 8) EDL could be included in the hardware combination:

1. Turn off the phone.


2. Press the buttons Volume up + Volume down + Power.




3. Connect the USB- cable to the PC.




4. Hold the buttons for 10-15 seconds until Qualcomm HS-USB QDLoader 9008 appears in Device Manager.

On models newer than 2019, this method does not work - the manufacturer turned off hardware activation EDL Protect against unauthorized access.

2.Testpoint (requires disassembly)

The most reliable, but also the most risky way is to close the test point on the motherboard, which is a special contact that, when you close it, turns the phone into a test point. EDL. Instructions:

Turn off the phone and remove the SIM- card and memory card|

Remove the back cover (need a mediator or sucker)|

Disconnect the battery (required!)|

Find Testpoint on the board (see diagrams for your model)|

Prepare tweezers or a needle to close-->

Examples of the location of test points:

• 📱 Redmi Note 10 Pro: Two pins next to battery connector, signed EDL;
• 📱 POCO X3 NFC: contacts under a metal screen, next to the processor;
• 📱 Mi 11 Lite: Testpoint hidden under heat pad.

Process:

1. Close the testpoint with tweezers.
2. Connect. USB-cable to PC (the phone must be turned off!).
3. Hold the circuit for 5-10 seconds until Qualcomm appears in the Device Manager HS-USB QDLoader 9008.

⚠️ Warning: Incorrectly closing the testpoint can damage the fee. If you are not sure about your soldering skills, you should consult a specialist.

3. Through ADB/Fastboot (if the phone is turned on)

If the phone is still loading (albeit with errors), you can try to transfer it to the phone. EDL team-wise ADB or Fastboot:

Method 1: ADB (if USB debugging is enabled)


adb reboot edl




Method 2: Through Fastboot



fastboot oem edl

The success of the method depends on the firmware version and model. For example, on the Redmi Note 9 Pro, the fastboot oem edl team works, and on the Redmi Note, the team runs on the same model. POCO F3 — If the team doesn't work, try the alternative:

fastboot oem select_display_panel

After execution of any command, the phone should be restarted in mode. EDL. Check this out in Windows Device Manager (Qualcomm device should appear) HS-USB QDLoader 9008).

💡

If the adb reboot edl command doesn’t work, try getting root rights through Magisk or a temporary patch first. TWRP. It will increase the chances of success.

The necessary tools to work with EDL

To flash the phone through EDL, You'll need it:

Important: Use only official firmware from Xiaomi’s website or trusted sources (e.g., the official firmware, XDA Developers: Third-party firmware may contain malicious code or be unstable.

Also, check out the Mi Flash Tool version:

• For models up to 2020, Mi Flash 2018 is suitable;
• New devices (e.g. Redmi Note 11) need a 2021 version+.

Step-by-step instructions for firmware through EDL

When the phone is in mode EDL, You can start the firmware. Follow the instructions:

1. Install Qualcomm drivers: Download QcomDLoader.exe from the official website; Disable the verification of the digital signature of drivers in Windows (via gpedit.msc); Connect the phone in mode EDL Wait for the driver to install.
2. Launch Mi Flash Tool: Select the downloaded firmware (unpack the archive into a folder without Cyrillic!); Device field should show up COM-port, COM3); Press Refresh, then Flash.

Wait for completion

• The process will take 5-15 minutes;
• Do not turn off the cable and do not interrupt the firmware;
• At the end of the phone will automatically restart.

If the firmware is terminated with an error (for example, Flash Write Failed), check:

• 🔌 Cable: Use the original cable USB-Xiaomi;
• 🖥️ Port port USB: Connect to the back port of the PC (not via the hub!);
• 📁 Firmware: Download it again (maybe the archive is damaged).
