When your favorite smartphone turns into a useless piece of plastic and glass, it always takes you by surprise: the screen does not light up, there is no vibration, and the connection to the computer causes only the sound of the connection. USB-It's called a brick in enthusiastic circles, and for Xiaomi owners, it's a familiar phenomenon, especially after a failed firmware experiment.
Don't panic and bring it to a service center, where you're going to be asked to do a round sum for flashing it, and in most cases, you can actually revive it yourself using standard tools from the developers, and you just need to understand where the device is going to die, and you need to choose the right algorithm.
Further manipulation requires careful attention, as a mistaken action can lead to complete data loss or, in rare cases, hardware failure. We will look at all the available methods of resuscitation, from simple reboots to deep recovery through EDL Mode.
Diagnostics of the device status: Soft brick and Hard brick
Before you start to act, you need to clearly define the type of malfunction, it directly depends on the choice of software and the sequence of steps, conventionally all problems are divided into two types: software failure (Soft brick) and hardware or critical software failure (Hard brick).
In the first case, the phone is showing signs of life: vibrating when turned on, the Mi logo lights up, the Recovery menu or Fastboot appears, but the operating system does not load, which is the most favorable scenario, which is solved by software methods without opening the case.
The second case, known as the Hard Brick, is characterized by a complete lack of response: the screen is black, the indicators are not on, the computer does not see the device in normal mode, but if the cable connects to the Windows Device Manager port Qualcomm HS-USB QDLoader 9008, then the hope is an emergency boot mode.
- 📱 Soft brick: The phone turns on but cyclically reboots or hangs on the logo.
- 💻 Fastboot Mode: The screen shows a hare fixing an android, the device is determined by a PC.
- 🔌 EDL Mode: Black screen, but computer detects Qualcomm port for deep firmware.
⚠️ Note: If the device is defined as “Unknown Device” or not at all when connected to a PC, the problem may lie in the hardware: a burned-out power controller or a plume break.
Accurate diagnosis will save you time and nerves. Trying to flash a brick in EDL mode with Fastboot methods will only lead to error, and waiting for a battery to be charged in deep sleep mode can take hours.
Preparation of the workplace and necessary tools
The success of the operation depends on 90% of the quality of preparation. You will need a computer with Windows operating system (preferably version 10 or 11), a good service. USB-cable and stable Internet connection for downloading files.
A critical element is installing the right drivers; without them, the computer will not be able to “see” the phone in special boot modes. Standard Windows drivers are often not suitable for Xiaomi protocols, so they must be installed forcibly.
You should also take care of the battery charge. If possible, set the phone to charge for at least 30-40 minutes before the manipulation, even if the screen does not respond. Low charge can interrupt the process of writing system files, which will aggravate the situation.
☑️ Checklist for preparations for recovery
We will use the Mi Flash Tool, the official software that allows you to download system images to the device's memory, and you should only download it from trusted resources or the official Xiaomi forum.
Recovery Methods through Recovery Mode
If your smartphone is still responding to the button combinations, try to enter recovery mode. This is the most gentle method, which does not require a connection to the PC at the initial stage.
In the Recovery menu, you have volume buttons (up/down) and you have power buttons to select. We're interested in Wipe Data. You can select it and confirm the action. This will delete all user data, but it can eliminate the system file conflict that caused the freeze.
If a simple reset didn’t work, you can try reinstalling the system through a local update. To do this, you need to rename the firmware file in.zip format to update.zip and place it in the root of internal memory (if the phone is defined as a drive) or select it through the Connect with MIAssistant menu.
| Action. | Button combination | The result |
|---|---|---|
| Entrance to Recovery | Volume + and Nutrition | Recovery menu (Main Menu) |
| Entrance to Fastboot | Loudness - and Nutrition | Screen with a hare (Fastboot) |
| Forced reset | Food (10-15 seconds) | Vibration and logo |
| Exit from Recovery | Item Reboot | Normal system loading |
⚠️ Warning: Wipe Data permanently deletes photos, contacts and apps. If data is critical, try the Mi Assistant method first.
Recovery is effective in software conflicts after updating or installing incompatible applications, but if the bootloader or system partition is damaged, this method may not work.
💡
If the Recovery menu does not appear, try connecting the phone to your computer via USB-Sometimes the external power will stimulate the transition to recovery mode.
Fastboot and Mi Flash Tool
Fastboot mode is the main tool for deep recovery Xiaomi. If the phone is determined in this mode (the screen with a hare or the port in the Device Manager), the chances of success are very high. You will need a firmware archive that has the extension.tgz, not.zip.
Unpack the firmware archive in the root of the C disk so that the path does not contain Cyrillic and is short, for example: C:\rom\. Run the Mi Flash Tool on behalf of the administrator. Press the Refresh button, and if the drivers are installed correctly, you will see the serial number of the device.
At the bottom of the utility window, there are three firmware options. Clean all is the cleanest and most recommended option. It completely erases memory and installs a fresh system. The Save user data variant tries to save files, but in the treatment of the brick, it often causes errors, as old files can conflict with new ones.

What to do if Mi Flash is making an error?
It’s important to remember about anti-rollback protection. Xiaomi forbids you to roll back on older versions of Android. If you try to flash the old firmware on a new Android, the phone can get a hardware lock that’s hard to unplug.
Emergency Recovery with EDL Mode (9008)
When the phone doesn't respond to buttons or screens, it's EDL (Emergency Download) mode, a low-level mode of Qualcomm processors that lets you write data directly into memory without the bootloader, and entering this mode on modern models often requires disassembling the case and closing test points on the board.
The process looks like this: you remove the back cover, disconnect the battery, find two special points (Test Point) on the motherboard, close them with tweezers and, without opening, connect. USB-In the Device Manager should appear port Qualcomm HS-USB QDLoader 9008.
Mi Flash is also used for firmware in this mode, but there is a caveat: modern phones require an authorized Mi Account with a high level of access. A typical user will not be able to flash the phone to EDL without paid services or accessing service centers that have authorization.
- 🔧 Disassembly: Careful opening of the hull and disconnection of plumes are required.
- ⚡ Short-term connection of test points for entry to 9008.
- 🔐 Authorization: A special account is required to record firmware in EDL.
⚠️ Warning: Self-opening of the phone will void the warranty. If the device is warranty, it is better not to risk and contact the official service.
There are also software methods for logging into EDL via ADB commands, but they only work if the phone is even partially functional, and for a completely dead device, physical circuiting is the only way.
💡
EDL (9008) is the last frontier of salvation when other methods are powerless, but it requires special skills and often paid authorization.
Common Errors and How to Resolve Them
In the recovery process, users often encounter error codes, such as a “Missmatching image and device” error that means you are trying to flash the firmware from another model. Always check the code name of the device (e.g. cepheus, davinci) that must match the firmware file.
The “Anti-rollback check failed” error is an attempt to roll back a version. There is no solution other than to look for firmware of the same or a newer version. Ignoring this rule can lead to irreversible consequences for the bootloader.
If the process is stuck on a certain percentage (for example, 15% or 99%), try changing the process. USB-port (use ports) USB 2.0 on the back of your PC, replace your cable or restart your computer.Sometimes it helps to install an older version of Mi Flash (e.g., 2018 version).
Remember that after a successful firmware, the first download can last up to 10-15 minutes. Don't panic if the phone hangs on the Android or Mi logo for a long time.
