Loss of access to the device, sale of a gadget or a critical system failure are just a few of the scenarios where the user needs to completely clear the internal memory of the smartphone. Unlike a standard reset via a menu, deleting data through a computer gives deeper control over the process and is often the only way to resuscitate the locked device. If your Xiaomi stopped responding to touches or you forgot the pattern lock, the PC becomes the main rescue tool.
Modern cleaning methods involve the use of special utilities and debugging protocols that allow you to initiate formatting of partitions of the system remotely. This action irreversibly destroys photos, contacts, correspondence in messengers and installed applications. So before starting any manipulations, you should make sure that all important files are copied to an external medium or to the cloud storage, since data recovery after formatting through ADB or Fastboot is almost impossible without specialized expensive equipment.
In this article, we will discuss proven ways to clean the memory of Redmi and Poco devices using a personal computer, you will learn how to use built-in debugging tools, official software to unlock the bootloader and third-party tools. Each method has its own application characteristics depending on the state of the operating system of your gadget.
Workplace preparation and necessary components
Before embarking on radical cleanup measures for the file system, it is necessary to ensure a stable connection between the smartphone and the PC. USB-Cheap charging cables often do not support data transmission, which will lead to errors when trying to send a command to reset.
You will need a computer running Windows, as most of the specialized utilities are optimized for this platform, and it is also critical to install the current drivers for your device, otherwise the computer will not see the phone in debugging or boot mode.
- 🔌 Original. USB-cable or certified analogue with data transmission support.
- 💻 PC with Windows 10 or higher and free USB-port.
- ☁️ Backup of important data on an external disk or in the Mi Cloud.
- 🔋 Charge the device at least 60% to avoid sudden shutdown during the process.
⚠️ Warning: Using a faulty cable can short-circuit or interrupt the firmware process, turning the phone into a brick".

Cleaning through ADB (Android Debug Bridge)
The most versatile way to remove all data from Xiaomi phone via a computer is to use the Android Debug Bridge toolkit, which works even if the touch screen is partially non-functioning, but the system is booting. To work, you need to activate the developer mode and allow debugging over USB in the device settings.
Once you connect your smartphone to your computer and install the SDK Platform-Tools, you get access to the command line with administrator rights. By typing in a dedicated command, you initiate a factory reset process that completely clears the /data partition. This is equivalent to a hard reset, but it's done software-wise from an external device.
The process is as follows: Open the command line in the tool folder. ADB and type in the adb reboot recovery command to go into recovery mode, or use a direct reset command if supported by your firmware version. In some cases, root rights are required, but the standard adb shell recovery command is --wipe_data often works on stock assemblies MIUI hyperos.
What if your computer can’t see the device in ADB mode?
Method Two: Reset via Fastboot and Mi Unlock Tool
If the operating system is damaged so much that you can’t log in to settings, Fastboot mode comes to the rescue. This is a low-level protocol that allows you to control the device before the OS boots. The official Mi Unlock Tool utility is usually used to unlock the bootloader, but the unlocking process itself involves mandatory complete cleaning of all user data for security purposes.
To use this method, you need to switch your smartphone to Fastboot mode, holding the power and volume buttons simultaneously, and after connecting to your PC and running the Mi Unlock program, the system will require authorization through your Mi Account account.
The Mi Unlock unlock process automatically formats all memory partitions, one of the most reliable ways to ensure that data is permanently deleted, but there are time constraints to consider: new devices may require waiting 7 to 168 hours after an account is attached.
| Characteristics | Recovery mode | Fastboot mode | ADB mode |
|---|---|---|---|
| Access to the system | Not required | Not required | Phone needs to be turned on |
| Difficulty | Low. | Medium | Tall. |
| Risk of data loss | 100% | 100% | 100% |
| The need for a PC | No (buttons) | Yes. | Yes. |
💡
Before unlocking the loader, be sure to remove SIM-MicroSD card and memory card to avoid accidental formatting or file system damage.
Use of Mi PC Suite and alternative gates
The official Mi PC Suite (also known as Mi Phone Master) is designed to manage content, but in some versions and for certain models it allows you to reset the device. The interface of the utility is graphical and clear, making it suitable for users who do not want to work with the command line.
There are also modified versions of these programs from third-party developers that open up hidden features of the service. However, using unofficial software always carries risks. You can accidentally install malware on your computer or damage the system files of the phone if the utility does not correctly interpret the model of the device.
When working with any software to control the phone, it is important to monitor the status of the connection. If the process is suspended during the loading phase of percent, you should not immediately turn off the cable. Often the system simply waits for confirmation of action on the smartphone screen or the completion of background recording processes.
Remote cleaning through Find Device
In situations where a phone is lost or stolen, physical access to it via cable is impossible, but it is still necessary to delete the data. Xiaomi's Find Device service allows you to remotely initiate a factory reset. This action will also delete all data stored on the device, making it inaccessible to attackers.
You have to go to the official website of the service from any computer, enter your Mi Account data and select a locked device from the list. The cleanup command will be sent over the Internet as soon as the phone is online. This is an effective way to protect personal information, but it requires the pre-activation of the "Device Search" function and the availability of Internet on the smartphone.
It’s worth noting that once cleaned, the device can request a password from a Google or Mi Account the next time you try to turn it on, a standard anti-theft measure known as FRP (Factory Reset Protection), which you can’t get around without knowing the owner’s credentials.
⚠️ Note: Remote cleaning through Find Device is possible only if the phone is connected to mobile Internet or Wi-Fi.
Possible problems and ways to solve them
When deleting data, users often encounter driver errors. Windows Device Manager can display the phone as "Unknown Device" or "Android." In this case, you need to manually update the driver by specifying the path to the folder with ADB or Fastboot drivers, which can be found in the SDK Platform-Tools.
Another common problem is antivirus blocking. Some security programs perceive tools for working with the bootloader as potentially undesirable. Before starting the procedure, it is recommended to temporarily disable the antivirus or add a tool folder to the exceptions.
If the phone goes into an endless bootloop after trying to reset, this may indicate damage to the system partition, in which case simple data cleaning will not help - you will need to completely flash the device through the Mi Flash Tool program using the Fastboot firmware image.
💡
If standard methods don’t work and the phone doesn’t respond to commands, the only solution is to flash through the Mi Flash Tool in EDL mode, which may require an authorized account.
