Owning a modern Xiaomi smartphone is often fraught with a desire to experiment, but sometimes the user is faced with the need to completely remove the current operating system. The reasons can be different: a critical software failure, infection with viruses that are not removed by standard methods, or the desire to change the firmware region to a global one.
Before you take action, you need to realize that the complete deletion of data is irreversible. All your photos, contacts, correspondence and installed applications will be destroyed without the possibility of recovery through standard Android tools.
There are several levels of depth of intervention in the device's software, from relatively safe resets through the settings menu to low-level reflashing through Fastboot mode using a computer. The choice of the specific method depends on the current state of your gadget: whether it turns on, responds to commands or is in a "brick" state.
β οΈ Attention: Any manipulation of system partitions risks turning the device into a non-functioning device. USB-The cable is good and provides a stable connection.
Preparation of the device and necessary tools
The success of the operation to replace or remove firmware depends on the quality of preparation, you will need not only the smartphone itself, but also a personal computer with the Windows operating system, since most utilities for working with Xiaomi are optimized for this platform. It is also critical to have an original or quality certified USB-A cable that can transmit data, not just charge the battery.
You need to install specialized drivers on your computer, and without them, the operating system can't correctly identify your phone in debugging modes. Most commonly, ADB Drivers and Fastboot Drivers are used. These are the foundations on which the entire process of interacting with your PC with your smartphone is built. If the drivers get incorrect, the commands simply won't reach the device.
βοΈ Firmware readiness check
You also need to activate the developer mode on the phone itself, if it's still available for use. You need to go to Settings β About phone and press the build number seven times quickly. Then you'll see a new option on the menu that contains the switches you want to use. Without activating USB debugging, many of the computer's commands will be ignored by the phone.
Full Reset Method through Recovery Mode
The most affordable way to demolish user data and return the system to factory status is to use the built-in Recovery Recovery menu, which does not require a computer connection and is suitable for situations where the phone is turned on but is not working correctly. The main recovery menu usually supports only English and Chinese, so it is important to know basic navigation.
To enter this mode, you need to turn off the device completely, and then press the combination of the buttons: volume up and power button. Hold them until the Mi or Redmi logo appears. Once you enter the menu, you will see a list of commands. We are interested in Wipe Data. The choice is made by volume buttons, and confirmation is by the power button.
- π± Wipe Data β erases all user data, cache and settings, returning the phone to the state βout of the boxΒ».
- π Wipe All Data β A deeper cleanup, often requiring password confirmation from a Mi Account to protect against theft.
- π Connect with MIAssistant β a mode for connecting to a PC and firmware through an official utility if a standard reset does not help.
Once you select the Wipe All Data, the system will request confirmation, often requiring you to enter a graphical key or password if the lock screen is active, a security measure against unauthorized access, the cleaning process takes one to five minutes, after which the phone automatically restarts, and the first turn on after such a reset will last longer than usual.
β οΈ Note: If the phone was enabled Mi Cloud and the function "Find the device", after reset, the system will require you to enter the username and password from the Mi Account.

Using Fastboot Mode for Deep Cleaning
Fastboot is a low-level protocol that allows you to control the device bootloader directly from your computer. Unlike Recovery, there is no GUI, and all commands are entered through the console or specialized programs, and this mode is where you demolish old partitions before writing new ones, making it an indispensable tool in case of serious failures.
To put Xiaomi into Fastboot mode, you turn off your phone and press down the power and volume buttons at the same time. The screen will show an image of a rabbit repairing an android that says FASTBOOT. Connecting the device to a PC will make you hear the sound of the new hardware being connected. In the Device Manager, it will be identified as Android Bootloader Interface.
This mode is often used by the Mi Flash Tool, which allows you to not only install new firmware, but also clear memory. There are three options in the program interface when you run the firmware, and one of them is clean all. This option forcibly formats all partitions, removing any previous firmware, whether official or custom.
| Mode of work | Essential tools | Level of risk | Data retention |
|---|---|---|---|
| Recovery | The phone. | Low. | No (complete removal) |
| Fastboot (Mi Flash) | PC, cable, drivers | Medium. | No (complete removal) |
| EDL (9008) | Special cable, authorization | High-pitched | No (complete removal) |
It is important to understand the difference between the firmware modes in Mi Flash. The clean all option simply erases data but retains the partition structure. The clean all and lock option does the same, but re-blocks the bootloader, which is necessary to return the warranty or use banking applications that do not work on unlocked devices.

If your computer canβt see your phone in Fastboot mode, try it. USB-port USB 2.0 at the back of the system unit) or reinstall drivers by manually selecting them through the Device Manager.
Firmware through Mi Flash Tool: step-by-step instructions
The process of completely replacing the firmware with memory cleaning requires careful adherence to the sequence of actions. First, you need to download the firmware image with the.tgz extension (for Fastboot) from the official website. The archive must be unpacked into the root folder of the disk so that the path to the files is short and does not contain Cyrillic, for example, C:\ROM\.
Launch the Mi Flash Tool on behalf of the administrator. Press the Refresh button to detect the connected device. If it goes well, the serial number will appear in the list. Now you need to choose the path to the unpacked firmware by pressing the Select button. At the bottom of the window, select clean all mode.
After checking all the parameters, press the Flash button, and a process will start, which is visually displayed by the progress bar and the green success indicator at the end, at which point it is strictly forbidden to turn off the cable or interrupt the power, since the recording goes directly to the memory chips, and any interruption can lead to irreversible consequences.
When the process is complete, the phone will automatically reboot. 10-15 So if you see a language selection welcome window after you download, it means that the old firmware has been successfully demolished and a new one installed.
EDL mode: restoration of the βbricksβ
If the phone doesn't respond to any buttons, the screen is black and the computer makes the device connect sound, but doesn't identify it as Fastboot, most likely the device has gone into EDL (Emergency Download Mode) mode. On computers, this device is defined as Qualcomm HS-USB QDLoader 9008. This is a deep diagnostic and recovery mode.
You can either program (if you have access to ADB) with the adb reboot edl command or hardware. Hardware login often requires disassembling the case and closing special contacts on the board (Test Points) when connecting the cable to the PC. For Xiaomi models with a secure bootloader, logging into the EDL often requires an authorized service center account.
The EDL firmware process is similar to Fastboot via Mi Flash, but requires selecting the appropriate COM port in the settings. The write speed in this mode is lower and the risk of error is higher due to direct memory work. This is an extreme measure when other methods do not help to bring the device back to life.
- π Test Points β special contacts on the board, the closure of which puts the processor in boot mode.
- π» COM Port β the port you need to select in Mi Flash to communicate with your device in 9008 mode.
- π Authorized Account β an account with the rights of a service engineer, necessary for the firmware of many modern Xiaomi models.
β οΈ Attention: Entering mode EDL Xiaomi is often blocked by the manufacturer on new models, and attempts to circumvent this protection by unofficial methods can lead to the final failure of the motherboard.
Frequent mistakes and ways to solve them
When you demolish firmware, users often encounter errors, and one of the most common is Missmatching image and device, which means you're trying to flash a firmware designed for a different phone model. For example, you can't flash Redmi Note 10 with the Redmi Note 10 Pro firmware. Always check the codename of the device, which must match the firmware file name and the phone specifications.
Another common problem is the Flash error or the hanging on a certain percentage, which is often related to quality. USB-Try using another cable, preferably short and without unnecessary bends, and try connecting the phone directly to the PC motherboard without sliding over the phone. USB-hubs and front panels of the body.
If the phone goes into an endless bootloop after firmware, the persist or modem partition may have been damaged. In this case, you may need to re-rout the firmware with full cleaning or restore specific partitions through Fastboot commands. For beginners, the safest way is to repeat the clean all procedure again.

90% of Xiaomi firmware errors are due to the wrong firmware type (Recovery instead of Fastboot) or the use of low-quality firmware. USB-cable.
If you move from Chinese firmware to global, the types of downloaders must match (or be unlocked). Trying to change the region with the bootloader closed often leads to the Can't validate current image error. In such cases, pre-unlocking through the official Mi Unlock website is required.
