Xiaomi’s modern smartphones have become powerful multimedia centers, where gigabytes of photos, documents and app cache are stored. Sooner or later, every device owner faces the question of how to quickly and efficiently copy data to a computer or free up space by gaining direct access to the file system. Standard methods of connection often work automatically, but situations with damaged drivers or specific MIUI settings can be difficult.
There are several proven ways to establish a connection between a gadget and a PC, starting from the basic one. USB-The choice of the specific method depends on whether the device screen is turned on, whether the Bootloader is unlocked and which version of the operating system is installed. In this article, we will discuss in detail all the current options that will help you manage internal storage and external storage. SD-loss-of-data.
Before you get into the tricky stuff, you need to make sure that the physical connection is working, and often the problem is that the cable is poor, it's just charging, it's not transmitting data, and if you're in this situation, the first thing you do is replace the wire with an original or certified high-speed cable.
Connection through USB-cable MTP
The most common and easy way to access files is to use a full-time USB-When you first connect to your computer, Android defaults to Charge Only, which hides files from prying eyes for security reasons. You need to switch this setting yourself so that your PC sees the device as an external drive.
When you connect your devices, lower the notification curtain on your smartphone screen, and you'll see a USB connection system message. Click on it to open the mode selection menu. To access all folders, including DCIM, Download, and MIUI, you'll need to select the file transfer (MTP) option.
⚠️ Note: If the computer does not respond to the connection even after the mode selection MTP, Try to insert the cable into another. USB-port, preferably located directly on the motherboard, rather than through USB-hub.
In some cases, you need to install drivers, especially on operating systems older than Windows 10. The system can automatically find the necessary components through the update center, but sometimes you have to download Mi PC Suite or universal ADB drivers from the official website of the manufacturer. After successfully installing drivers in My Computer, a new disk will appear with the name of your model.
If the standard method doesn't work, check the debugging settings. Enabling developer mode allows the system to interact more deeply with external devices, especially for older versions of MIUI firmware, where software failures can occur when shaking hands.
Configure the developer mode and debug over USB
Deeper file management and specialized software often require activation of developer mode.This hidden menu provides access to critical features, including USB debugging. Without this step, many advanced data recovery or system cloning programs simply won't see your phone.
To activate the desired mode, go to Settings → About the phone. Find the line "Version." MIUI» And press it fast. 7-10 Once you have a "You've become a developer" message, go back to the main settings menu, select "More" and find "Developers».
In the menu, find the debugging switch. USB And you activate it. You'll get a warning about the potential risks, you'll confirm the action. Now, when you connect to your PC, you'll see a confirmation request on your smartphone screen. RSA-Make sure to click "Allow" so that your computer has permanent access.
- 🔌 Always confirm pop-ups requesting access when you first connect to a new computer.
- 🛡️ Disable debugging when not using it to reduce the risk of unauthorized data access through public charging stations.
- 🔄 Reboot the device after debugging if the computer still doesn’t identify the phone correctly.
It is important to note that new versions of HyperOS or MIUI 14+ You may need to log in to a Mi Account with a phone number attached, which is a security measure that complicates the process, but protects your user data from theft. SIM-card, the system can block access until re-verification.
Why does the developer mode disappear?
Wireless access via Wi-Fi and FTP
When there is no cable or connector at hand USB It's damaged, wireless technology comes to the rescue. MIUI (Or "Conductor") has a convenient function to create FTP-This allows you to access the memory of the phone as a network folder through a Wi-Fi router.
To start the function, open the Explorer app, go to the Service tab or click on the menu (three bars) and select Network Access. Click Start and the system will give you the view address. ftp://192.168.1.XX:XXXX. This address must be entered in the address bar of any folder on the computer.
The main advantage of the method is the lack of wire binding and the ability to transfer files at a speed comparable to USB 2.0, if you use the modern standard Wi-Fi 5 or Wi-Fi 6. However, it is worth considering that the transfer speed depends on the quality of the signal and the load of the channel.
| Parameter | USB Cable | Wi-Fi (FTP) | Bluetooth |
|---|---|---|---|
| Transmission speed | High (up to 480 Mbps) | Medium/High (depending on the router) | Low (up to 3 Mbps) |
| Stability | Maximum | Depends on the signal. | Medium |
| Convenience | Requires cable. | Total discretion | Doesn't require a network. |
| Battery charge | Replenishing. | Spent. | It's slow. |
FTP is especially useful for regular photo and video backups, and you can set up an automatic script on your PC that will pick up new files from your DCIM/Camera folder when you connect to your home network, eliminating the need to manually copy gigabytes of data every night.
💡
For maximum Wi-Fi speed, make sure that both your phone and your computer are connected to a 5GHz network. A 2.4GHz network can significantly limit the speed of copying large files.
Using ADB for Advanced Access
For users who need full control of the file system, including access to system partitions, Android Debug Bridge (ADB) is an indispensable tool, which requires the installation of platform tools on the computer and allows you to manage files through the command line, bypassing the limitations of the graphical interface.
Before starting work, make sure that the minimum set is installed on the computer. ADB-After you plug in the phone with the debugging enabled, USB open the command line (CMD) Or PowerShell in the tool folder. Type in the adb device command to check the visibility of the device. If it's successful, you'll see the serial number of the gadget.
adb pull /sdcard/DCIM/Camera/ photo_backup/
adb push new_video.mp4 /sdcard/Movies/Adb pull copies files from phone to computer, and adb push uploads them back, which is the perfect way to get data from a device that's broken but the sensor is partially working, or when the system is getting stuck during boot. ADB is low-level, often ignoring software locks on the interface.
⚠️ Be careful when deleting files through ADB. Adb shell rm removes data without recovery from the cart, as it bypasses standard Android security mechanisms.
ADB can also make full backups of applications and data, which cannot be done with standard tools without root rights. The adb backup team creates an archive that can be deployed on another device. However, on modern versions of Android, many applications block the creation of such backups for security reasons.
Access to memory when a broken screen
When the screen of Xiaomi smartphone is broken, but the device itself is functioning, is one of the most stressful. If the sensor does not respond, the standard switching of USB modes becomes impossible, in which case external input devices and special adapters come to the rescue.
If your phone supports OTG (On-The-Go) technology, you can connect a normal computer mouse to it via a USB-Type-C adapter. The cursor will appear on the screen (even if the picture is not visible, you can act by touch or projection). With the mouse, you can unlock the phone with a pattern lock and select the file transfer mode.
- 🖱️ Use it. USB-power hub, if you need to connect both a mouse and a flash drive to copy data.
- 🖥️ Connect the external monitor via the Type-C to adapter HDMI, If the phone display is completely black, the system works.
- ☁️ Use cloud services (Mi Cloud, Google Photos) if your phone is connected to Wi-Fi to download data remotely without touching your device.
If the sensor is completely dead, and HDMI-The output is not supported by the model, but we can hope for previously established permissions. USB If you have been enabled in advance, you can try using remote screen control programs such as Scrcpy, which broadcast the image of the phone on the PC and allow you to control it with your mouse.

Frequent problems and their solution
Even if all instructions are followed, users may encounter errors: a computer may only see the phone as a charger, ignore it completely or give out a driver error, most often the problem lies in the physical wear of the port or software conflict.
One common cause is contamination of the USB connector in the phone itself. Pocket pile and dust are compressed at the bottom of the port, preventing the cable from entering the end and closing the data contacts. Careful cleaning of the connector with a wooden toothpick or compressed air often solves the problem instantly.
If the problem is software, try resetting USB. Go to Settings → For developers and find the option “Default USB Configuration.” Set the value “File Transfer.” Also, disabling “Debug over USB” can help, restarting the phone and re-enable this feature.
⚠️ Warning: Do not use damaged cables with bending or bloating insulation.Unstable voltage from poor contact can damage the phone's power controller, leading to costly repairs.
In rare cases, the culprit is an antivirus on your computer or a firewall that blocks an unknown device. Try temporarily disabling the protection or connecting the phone to another PC to rule out the malfunction of the smartphone itself. If the other computer is working, look for a driver conflict in your main machine's Device Manager.
