Xiaomi Redmi 4X, despite its age, remains a reliable device that often requires interaction with a personal computer to transfer media or backup data. Users face the need to synchronize the gadget with Windows or macOS for various reasons, from simple copying photos to deep debugging of the system. Modern operating systems tend to automatically configure, but in the case of MIUI, manual intervention is often required to activate the desired transmission protocols.
In this guide, we will take a detailed look at all the available methods to connect your Redmi. 4X You'll learn how to set it up correctly. USB-The interface, what drivers might be needed for stable operation and how to use wireless technologies to exchange data. MIUI, Often hides the user’s options.
The right connection is not just about copying files, but also being able to use your phone as a webcam, remote control, or external drive. It's critical to understand the difference between charging and data transfer modes, because by default, the device often blocks access to the file system for security purposes. Let's move on to the technical implementation of these processes.
Physical connection through USB-cable
The most common and quick way to establish a connection between a gadget and a computer is to use it. USB-But if you just put the cord in the port, you'll often see just a charging indication. USB-The port on Android devices is initially set to only power consumption. You need to switch the mode of operation of the interface yourself.
After connecting the devices, pay attention to the smartphone notification panel. There should appear a system message about the new USB-If you don't see any notifications, check the integrity of the cable: some cheap wires only support charging and don't have data lines. Use the original cable or quality analogue labeled (data transfer).
To activate the transfer of files, perform the following steps:
- 🔌 Get Redmi on board. 4X ce USB-port of the laptop with a reliable cable.
- 🔽 Unlock the screen and lower the notification curtain from top to bottom.
- 🖱️ Click on the notification "Charging through" USB" (or similar).
- 💾 In the menu that appears, select the "File Transfer" mode (MTP)".
Once you select MTP, the computer must make a distinctive sound of connecting the new hardware. My Computer or Windows Explorer will have a new drive with your phone's name. You can now move files freely between the device folders and the PC's hard drive. If the system doesn't respond, the computer may not have the necessary drivers.
⚠️ Note: If the computer makes a device error sound when connecting, and unknown hardware with a yellow exclamation mark appears in the Device Manager, you need to manually install drivers. ADB or MTP official website.
Configuring drivers and debugging mode
In some cases, standard Windows tools are not enough to correctly recognize an Android device, which is especially true if you plan to use specialized software to control your phone, take screenshots from your PC, or debug applications.
The Hidden Developer Menu in the MIUI shell is activated by default, but its contents are hidden. To access the advanced USB settings, go to Settings → About Phone. Find the MIUI Version line and quickly click on it 7-10 times in a row. The system will report that the developer mode is activated.
Now, the new option, "Additional" → "Developers" will appear in the settings menu. Inside this section, you're interested in the USB Debugging option. Turn it on with a slider. When you first connect to a computer with debugging enabled, you'll see a request on your smartphone screen for debugging permission from that computer. Make sure to tick "Always Allow" and click "OK."
☑️ Checking the developer's settings
Sometimes, even after debugging is enabled, the computer sees the phone only as a charger, so in the Developer Menu, find the default USB configuration and force the option to transfer files, which will force Redmi 4X to always offer a drive mode when connecting to a PC, ignoring the standard charging protocol.
Use of Wireless Wi-Fi Connection
If the cable is lost or the laptop ports are busy, you can use wireless connectivity. Wi-Fi provides enough speed to transfer documents, photos and even high-resolution video. There are several ways to do this, from built-in MIUI features to third-party applications.
The first method is to use a built-in file explorer MIUI. Open the Explorer app on your phone, go to the Service or Tools tab and select Remote Management (or"FTP"). Press "Run." The system will give you the address of the view. ftp://192.168.1.5:2121.
Type this address into the address bar of any folder on your computer. The phone's file system is now available over the network. The second method is using cloud services or specialized programs like Mi Drop (now ShareMe) or TeamViewer, which allow you to transfer files through a browser or client application without entering complex addresses.
| Connection method | Transmission speed | Stability | Difficulty setting up |
|---|---|---|---|
| USB Cable (MTP) | High (up to 40 MB/s) | Great. | Low. |
| Wi-Fi (FTP) | Mean (5-10 MB/s) | Depends on the router. | Medium |
| Bluetooth | Low (< 1 MB/s) | Good. | Low. |
| Cloud services | Depends on the Internet. | Tall. | Low. |
When using Wi-Fi, make sure that the laptop and smartphone are connected to the same wireless network. If you have a dual-band router, it is better to use 5 GHz for higher speeds, although 2.4 GHz will provide a longer signal range.
💡
For maximum Wi-Fi transmission speed, position your laptop and router in line of sight, avoiding concrete or metal obstacles that shield the signal.
Modem mode: Internet from phone to PC
Frequently connect Redmi 4X You don't need to go to a laptop for files, you need to go to the Internet. 4G/LTE It can be faster and more stable than public Wi-Fi. USB-The modem allows you to broadcast mobile Internet to your computer via cable, while charging the phone.
This function is activated in the settings menu. Go to Settings. → Wi-Fi Access Point (or "More" →"Modem mode. "" Here you'll see the switch"USB-It will only become active once the cable is physically connected to the computer.
Windows will automatically detect a new network connection, a monitor icon will appear in the tray, and in a few seconds the Internet should work, and the advantage of this method is that the connection is more stable and energy efficient than the distribution of Wi-Fi access points, since no battery life is spent on the radio module.
⚠️ Attention: When in use USB-Make sure you have a plan connected with unlimited traffic or a large data package. The computer can quickly consume traffic on background updates to the system and programs.
If the Internet is not available, check in the mobile network settings whether data transmission is enabled. Also in some cases, carriers block the distribution of the Internet; to bypass may require additional settings APN or the use of specialized software that changes the TTL packets.
Photo and video transfer: features of MIUI
Users often want to upload photos and videos from Redmi 4X to their computer. In the Android file system, media files are stored in specific directories, and knowing the path to them will save you time when searching for the right shots among the system debris.
The main folders are located at the root of the internal drive. Camera photos are usually taken from the path of DCIM → Camera. Screenshots are saved to the Pictures → Screenshots folder. If you used other applications to shoot, they could create their own folders, for example, WhatsApp → Media → WhatsApp Images for the messenger.
When copying large video files (4K or FullHD 60fps), the speed can drop, due to the peculiarity of the MTP protocol, which is not designed to stream gigabytes of data as efficiently as a regular flash drive, it is recommended to copy files in small portions or use archiving.
Where is the WhatsApp folder stored?
You can use the built-in gallery tools to quickly sort photos before transferring them. Select the right frames, click Share, and choose the mode of transfer if you don't want to mess with folders. However, for a full backup of original quality without compression by messengers, direct access via USB remains the best option.
Addressing common problems
Even if you follow all the instructions, you can crash: your computer may not see the Xiaomi Redmi 4X, reset the connection or display files with errors, and most often the problem lies in USB 3.0/3.1 ports, which sometimes conflict with old phone protocols.
Try connecting the cable to a USB 2.0 port (usually black, unlike blue USB 3.0) and replacing the cable with a shorter one also helps, as long cords have greater resistance and may not provide the necessary current strength for stable data connection.
If nothing helps, follow the following steps:
- 🔄 Restart your smartphone and laptop.
- 🔌 Use another one. USB-port, preferably on the back of the system unit.
- 🛠️ Remove the device from Windows Device Manager and update the hardware configuration.
- 📲 Check if the "Only Charging" mode is enabled in the developer settings.
In rare cases, the problem may be the damage itself. USB-If the cable wobbles or the connection disappears at the slightest movement, you may need to replace the connector in the service center.
