When a Xiaomi smartphone stops responding to commands, forgets its lock password, or gets into an endless reboot cycle, many owners are familiar with. Often the only solution is a complete reinstallation of the system or a hard data reset that cannot be performed by the standard means of the device itself, and it is at these moments that a personal computer comes to the rescue, allowing access to deep levels of file system management and service memory parts.
Using a computer to reset gives the user much more options than a simple combination of buttons in the Recovery menu. You get full control of the process, the ability to choose a specific version of the firmware and, critically, access to Fastboot mode, which bypasses most software locks. However, this method requires care, since careless actions can lead to complete loss of data or, in rare cases, to “brick” the gadget if you interrupt the power supply or turn off the cable at the wrong time.
In this guide, we will take a look at all the steps of preparing, installing the necessary software and the process of restoring the health of your Redmi or Poco. We will look at the official Mi Flash Tool, which is the industry standard for devices of this manufacturer. Understanding each step will allow you to avoid common mistakes and bring the device back to life even in the most difficult cases of software failures.
Workplace preparation and necessary components
Before taking action, a stable connection between the computer and the mobile device must be ensured. USB-Cables play a crucial role here: cheap wires often only provide charging without transmitting data, which will lead to connection errors at the most inopportune time. It is recommended to use the original cable, which came in the kit, or a certified analogue with support for high-speed data transmission.
The second critical element is the computer’s operating system itself. While Xiaomi tools can theoretically run through emulators on other platforms, native Windows environment (versions 7, 10 or 11) ensures the best driver compatibility. Make sure that there is enough free space on the hard drive, since firmware images can take up from 3 to 5 GB, and temporary files require additional space during the unpacking process.
⚠️ Warning: Before any manipulations, make sure that the battery charge of the device is at least 60%.A sudden power outage during the recording of system partitions can lead to irreversible damage to the bootloader.
You will also need a Mi Account. In modern versions of security firmware, linking to a company’s cloud service has become mandatory for PC reset operations. If you forget login details, the recovery process can be complicated by having to contact support or provide checks to purchase a device to prove ownership.
☑️ Preparation for discharge
Installation of drivers and tools Mi Flash
The computer will not be able to interact with the smartphone in service mode without special drivers. Standard Windows tools often do not recognize the device in Fastboot or EDL mode, displaying it as unknown hardware. To solve this problem, you need to install the Qualcomm HS-USB QDLoader package and standard Android ADB Interface drivers. Without these components, the flasher simply will not see the connected gadget.
The main tool for this task is the Mi Flash Tool, the official software distributed by Xiaomi for service centers. download the current version is best from proven resources or the official forum of developers MIUI, as older versions may not support new models of smartphones released in 2023-2026.
The process of installing drivers often causes difficulties for beginners. If the automatic installation did not work, you will have to use the Device Manager. Find a device with a yellow exclamation mark in the list, select Update Driver and specify the path to the folder with unpacked drivers. After successful installation in the Device Manager, the Android Bootloader Interface should appear when you connect your smartphone in the appropriate mode.
💡
Use it. USB-ports located on the back of the system unit (direct to the motherboard), as they provide a more stable voltage and signal than ports on the front panel or through the motherboard USB-hub.
After installing all the components, it is recommended to restart the computer, which ensures that all system services responsible for interacting with the computer. USB-The devices will run correctly and capture the new registry settings, and only then you can run the Mi Flash Tool on behalf of the administrator to avoid problems with access rights to system files.
Finding and Choosing the Right Firmware
The key to successful recovery is choosing the right image of the operating system. Firmware for Xiaomi is divided into two main types: Recovery and Fastboot. To reset via PC and Mi Flash, you absolutely need the Fastboot option. It is easy to distinguish it: the archive file has the.tgz extension, while the version for updating through the phone menu has the.zip extension.
Global firmware is labeled Global and has the letter M in its name (e.g. MIUI 14 Global). Chinese versions (China) may not have Google services built-in or have frequency restrictions, but they often update faster. Mix regions when resetting with extended memory clearing is usually possible, but this can lead to a loss of warranty or lock by region.
What is the difference between Clean All and Save User Data?
Upload firmware only from official sources or verified mirrors such as xiaomirom.com or miui.com. Files must be whole; after downloading, it is recommended to check the checksum of the archive to make sure there are no download errors.A damaged archive can lead to a verification error in the firmware process, which will interrupt the process in the middle.
It is important to consider the Android and MIUI versions. downgrade is often blocked by Anti-Rollback protection. If you try to install a firmware with a lower security number than the current one, the device may be permanently locked. Always check the current version and compare it to the one you plan to install.
Enter Fastboot Mode and Connect to PC
To start the reset process, you need to put the phone into a special diagnostic mode. On the device that is turned off, press the volume and power buttons at the same time. Hold them until the image of a hare repairing an android appears on the screen, or the inscription FASTBOOT, which means that the device is ready to receive commands from the outside.
Connect your smartphone to your computer through USB-Windows Device Manager should show new hardware. QHSUSB_BULK If you have an unknown device, the drivers are not installed correctly and you can't continue the procedure.
⚠️ Attention: Do not remove the cable USB During the flashing process, even if the program shows 99% progress, interrupting the recording of the boot sector is guaranteed to turn the phone into a brick, the recovery of which is possible only through paid service software.
Once you've successfully connected, launch the Mi Flash Tool. Press the "Refresh" button in the program interface. The list should show a connected device with its unique identifier. If the list is empty, check the cable, USB port, or re-install the drivers.
Step-by-step reset instructions via Mi Flash Tool
When the device is displayed in the program, we go to selecting a firmware file. Press the Select button and specify the path to the folder where the.tgz archive was unpacked. It is important to choose the folder that contains the images and images files inside. flash_all.bat, It's not the archive itself. It automatically checks the integrity of the files.
At the bottom of the Mi Flash Tool window, there are three options for performing an operation. To completely reset, select the Clean all option. This option ensures that all user data, accounts and settings are deleted, returning the phone to the “out of the box” state. The Save user data option leaves files but may not solve the problem of software errors, and Clean all and lock will also block the bootloader, which is not recommended if you are not sure of the origin of the firmware.
Once you select the settings, press the Flash button, and it will start a recording process that will take 200 to 600 seconds, and the log will show progress messages, and don't be alarmed if the phone reboots several times or the screen goes out, which is normal for partition re-marking.
Below is a table deciphering the main statuses that may appear in the process:
| Status in the log | Meaning | User actions |
|---|---|---|
| send | Transferring data to the device | Waiting, don't touch the cable. |
| receiving | Getting a response from the loader | Waiting. |
| flash success | Successful section recording | The process continues |
| error: can't open image | Error of access to the firmware file | Check the path and access rights |
When the process is complete, flash success will appear in the status, and the phone will automatically go into reboot. The first boot after reset can last up to 10-15 minutes, as the system performs initial application optimization and configuration of file structures.
💡
The main success of the operation is the choice of the “Clean all” mode and the use of stable USB-port without interruption of power throughout the recording process.
Solving common mistakes and problems
In the process, users often encounter a Missmatching image and device error, which means that the chosen firmware is not intended for this model. For example, you try to flash a global version on a Chinese device without properly unlocking the bootloader, or vice versa. The solution is one: find a strictly relevant code model (for example, Global Version for a device with RU or EU code).
Another common problem is the Anti-rollback check failed error, which is, as mentioned earlier, rollback protection, and if you see this error, it means that the device has a newer version of protection than the file you're using, and you need to find a newer version of the software, and it's very risky to try to get around this protection with software at home.
⚠️ Note: If the device after reset requires you to enter the Mi Account that was synced earlier, this is the protection function of the Mi Cloud Lock. Reset this protection through the PC without the owner's password is impossible - this is the level of protection against theft.
Sometimes the program freezes in the writing logo or writing tz stage. This may indicate poor contact in the port or a lack of power. USB-cable, preferably without curves, and connect directly to the motherboard, bypassing hubs and extension cords, and it is also worth checking whether the computer is power-saving mode for the computer. USB-port.
If the phone is not detected in Fastboot mode at all, but is responsive to connection, you can try entering EDL (Emergency Download Mode) mode. This often requires opening the case and closing special contacts on the board (Test Points), which is a complex hardware procedure and requires soldering skills. However, for most software failures, a regular button login is enough.
