Xiaomi Redmi 4X, released in 2017, is still popular due to its reliability and metal body. However, users often have difficulty syncing it with a personal computer to transfer photos, music or documents. Standard charging cable connection is often limited to power supply, leaving the device's file system hidden from the Windows operating system.
The problem is that Android is the default operating system that blocks access to data for security reasons. USB-This is a port so that the computer recognizes the internal memory or memory card as an external drive. In this article, we will discuss in detail all the stages of configuration, from choosing the right cable to installing specialized drivers.
Often, Redmi 4X owners mistakenly believe that a device is malfunctioning unless it is displayed in My Computer. In fact, 90% of the time it is only necessary to switch one option in a hidden menu or update the interface software. Let's look at a step-by-step algorithm that will help you establish a stable data exchange.
Equipment preparation and cable inspection
The first step to a successful connection is to physically verify the components used. Not all Micro-USB cables are the same: many of them, especially those with cheap accessories, are “chargeable” and have no internal data lines. You will need a quality cable that can support communication protocols.
Visually inspect the connectors for oxidation or dust, which is common in older devices. If the phone port is filled with pile from your pocket, contact may not be established even with a serviceable wire. Carefully clean the connector with a non-metallic object, such as a wooden toothpick.
- 🔌 Use the original cable or certified analogue labeled Data.
- 💻 Connect the device directly to the motherboard ports, avoiding USB-hub.
- 🧹 Check the cleanliness of the Micro-USB port on the Redmi smartphone itself 4X.
It is also worth checking the condition. USB-Sometimes the problem is a lack of power on a particular port or a software shutdown in the Device Manager. Try using different connectors, especially if you connect to a stationary PC at the back of the system unit.
If, after you change the cable and the port, the computer still makes the device connection sound, but does not define it as a drive, move to the software setting. Physical health is the base without which further action does not make sense.
Activation of File Transfer Mode (MTP)
After physically connecting your smartphone to your PC, Android defaults to Charge Only, a standard security behavior that prevents unauthorized access to data when you connect to other computers, and you need to manually switch this mode to MTP (Media Transfer Protocol).
Immediately after connecting the cable, unlock the Redmi screen. 4X. Swipe from top to bottom to open the notification bar. You should see the system message "Charge through" USB» or «USB-Connectivity.Click on this notification to reveal the available connection use cases.
☑️ Incorporation algorithm MTP
In the menu that opens, select File Transfer or File Transfer (MTP) and then the computer will hear the characteristic sound of new hardware detection, and a new device will appear in Windows Explorer. If this does not happen, you may not have the necessary drivers installed.
⚠️ Note: If the menu item USB does not appear after connecting the cable, try to turn on debugging USB And that's in the developer menu, which I'll talk about later, and sometimes it's like, "Wake up» USB-controller.
MTP is a universal standard supported by all modern versions of Windows without the need to install additional software, but older versions of the OS or specific configurations may require manual driver updates through Device Manager.
Setting up the menu for developers and debugging
If standard methods don't work, you need to activate advanced system settings. The developer menu in the MIUI shell is hidden by default, so that inexperienced users do not accidentally change the critical settings of the smartphone.
To activate the hidden partition, go to Settings → About the phone. Find the line "Version." MIUI» And press it fast. 7-10 After a series of clicks, a pop-up message will appear, "You've become a developer».
Path to setup: Settings → Advanced settings → For developersIn the menu that opens, find the option “Debug by USB” and activate it with a slider. The system will warn you of the potential risks – confirm the action. Also, this menu may contain the option “Default USB Configuration”, where you can immediately set the MTP mode so that you do not switch it manually every time.
- 🛠️ Activate the developer menu tapas according to the version MIUI.
- 🔓 Turn on the "Debugging by" slider USB».
- ⚙️ Check the configuration settings USB same-menu.
Sometimes after enabling debugging when connecting to a new computer on the phone screen there is a request for debugging permission from this device. RSA-You have to tick "Always Allow" and press "OK" or the connection will be reset.

Installation of ADB and Fastboot drivers
Windows 10 and 11 usually automatically locates the drivers for Redmi 4X through the Update Center, but if you see an Unknown Device or an exclamation point device in the Device Manager, you will need to manually install it.
The most reliable way is to install a universal Google USB Driver package or specialized software from Xiaomi.The official Mi PC Suite tool (Chinese version) contains all the necessary components to work with the file system of older models.
| Component | Appointment | Necessity |
|---|---|---|
| Google USB Driver | Basic support for Android devices | Tall. |
| Xiaomi USB Driver | Specific functions of MIUI | Medium |
| Qualcomm Driver | Loading mode (EDL) | Low. |
| ADB Interface | Debugging and management | Medium |
For manual installation, go to Device Manager, find your device (often marked with a yellow triangle), right-click and select Update Driver. Specify the path to the folder with the drivers unpacked, or let Windows find them automatically on the Internet.
⚠️ Warning: Do not download drivers from questionable aggregator sites. Use only official GitHub repositories or developer site xiaomi.com to avoid malware introduction.
Once the drivers are installed successfully, restart your computer, which is necessary to register new services correctly in the Windows registry, and in most cases, the problem is solved at this stage.
💡
If the driver is installed but the device is constantly reconnecting, try in Device Manager in Properties. USB-Root concentrator disable the option "Allow disconnection of this device to save energy».
Use of alternative methods of transmission
If a wired USB connection causes too much difficulty or the port is damaged, you can use wireless methods. For Xiaomi Redmi 4X, both built-in MIUI tools and third-party applications are relevant.
The built-in MIUI File Explorer has a Remote Management feature that allows you to access your phone files via a browser on a PC from the same Wi-Fi network, which is convenient for quickly transferring documents without finding cables.
You can also use popular cross-platform snails like Send Anywhere or Feem, which work on the principle of P2P and provide high transfer speeds comparable to USB 2.0, which is used in the Redmi 4X.
- 📡 MIUI Remote: built-in function for accessing through the browser.
- 📤 Send Anywhere: Quick Transmission by Access Code.
- 📂 FTP-server: use of Solid Explorer applications.
For activation FTP-In the file manager, click the menu (three bars), select Network Access and start the server. Enter the displayed address (e.g, ftp://192.168.1.5:2121) to the address bar of the Windows Explorer.
💡
Wireless methods are ideal for regular synchronization of small amounts of data, but USB-cable is a no-contest option for backing up the entire system or transferring video to the 4K.
Solving Common Connection Problems
Even if you follow all the instructions, there can be specific errors, and one of the common problems is that the computer sees the phone but doesn't show the memory, often due to file system damage or lack of access rights.
If the device is defined as a “Portable Device” with a yellow icon, try updating the driver in Device Manager by selecting from the list of “MTP Devices” –> “MTP USB-Device.” This will force Windows to use the correct protocol.
In cases where the phone is constantly in charging mode and ignores data commands, it may be damaged firmware or Android system files. In this situation, resetting network settings or, in extreme cases, a complete reset to factory settings (don’t forget to make a backup).
