Xiaomi and Redmi smartphones today have vast amounts of internal memory, becoming full-fledged multimedia centers. However, it is often necessary to quickly transfer gigabytes of photos, videos or documents to the big screen or back up important data. Direct connection to the PC remains the fastest and most stable way to exchange information, regardless of the speed of the Wi-Fi router.
Many users are faced with a situation where, after connecting the cable, the device only starts charging, ignoring data requests. This is standard Android security behavior that requires manual switching of the protocol. USB-In this article, we will discuss in detail the algorithm of actions for activating the drive mode (MTP), Consider the nuances of drivers and offer solutions for common technical failures.
Keep in mind that the proper operation of the interface depends not only on the settings of the phone, but also on the quality of the cable used. Cheap wires often only support charging, physically having no contacts to transmit data, which can be misleading even for an experienced user.
Equipment preparation and cable inspection
The first step before setting up is to physically connect the device. Make sure you are using an original or certified device. USB-It's almost impossible to visually distinguish a high-quality wire from a charging wire, so if the computer doesn't respond to the connection, try replacing the cord with another one that is known to be in good working order.
Connect your smartphone to the free port USB It is better to use the connectors located on the back of the system unit, as they are connected directly to the motherboard and provide more stable power and signal than the ports on the front panel or through the USB-hub.
After connecting, look at the smartphone screen. If the device is locked, the system may not show a connection notification for security reasons. Unlock the screen by swiping the notification curtain down to see the system message about USB mode.
💡
Use short cables up to 1 meter long to connect to a stationary PC. Long wires can cause a voltage drop, which makes it impossible for the computer to identify the device as a storage device.
Activation of File Transfer Mode (MTP)
By default, the MIUI or HyperOS operating system sets Charge Only mode, which is designed to protect data from unauthorized access when connecting to public charging stations, and you need to manually change this setting to see the phone's file system in order for the computer to see it.
Unlock the smartphone screen and lower the top notification curtain.Look for the "Charge through" notification USB» (or «USB-Connection. Click on it to reveal the list of available modes. Select File Transfer or MTP (Media Transfer Protocol).
Once you select the mode, the Windows system tray should hear the characteristic device connection sound, and a new drive will appear in My Computer with the name of your Xiaomi model. If this does not happen, you may need to confirm your permission to access data on the phone by clicking “Allow” in the pop-up window.
☑️ Connection check MTP
Configure debugging over USB for advanced users
If the standard MTP mode is unstable or you need access to system folders, you can activate debugging mode. Go to Settings → About phone and quickly click on the MIUI build number seven times. This will unlock the Developer Menu.
In the menu that opens, find the "Additional" section or "Developers" option immediately. Find the "Debugging by USB" switch and activate it. The system will warn you of the risks - confirm the action. This mode allows the computer to gain advanced access to the file system through special utilities.
⚠️ Attention: Debugging mode for USB Opens deep access to the system. Do not activate this feature on unfamiliar computers or public PCs to avoid identity theft.
When you connect the debugging phone to a new computer, you'll see a request on your smartphone screen for debugging permission from that computer. Be sure to check the RSA keyprint and press "Allow" or you won't have the connection installed. For normal file copying, this feature is redundant, but useful for creating full backups.
What is ADB in the context of file transfer?
Installation and update of drivers in Windows
Windows 10 and 11 usually automatically installs the necessary drivers for Xiaomi devices, but older versions of the OS or using specific models may require manual installation of ADB or MTP drivers.
If the device appears as "Unknown Device" or "Android" in Device Manager, right-click on it and select "Update Driver." Select automatic Internet search. If Windows does not find the driver, download the official Mi PC Suite or the universal Google USB Driver from the developer's website.
Sometimes manual driver installation helps MTP. In Device Manager, select “Update driver» → «Select a driver from the list of available «MTP USB-The device" and click "Next. " The system will force the standard media protocol driver to be installed, which often solves the problem of file invisibility.
| Driver type | Appointment | When to set up |
|---|---|---|
| MTP USB Device | Transfer of media files | To work with photos and videos through the Explorer |
| ADB Interface | Debugging and management | For advanced utilities and firmware |
| Bootloader | Loader | Only to unlock the loader |
| Fastboot | Firmware mode | To restore the system through MiFlash |
💡
The standard MTP driver is built into Windows. The problems are most often caused not by the absence of a driver, but by a faulty cable or the wrong choice of mode in the notification curtain.
Problem Solving: The computer can't see the phone
The situation where the phone is charging but files are not displayed is the most common.Apart from USB mode, the problem can be in the contamination of the connector.A careful inspection of the USB Type-C port for dust and pile, using a wooden toothpick or compressed air, as compressed dirt interferes with the tight contact of data contacts.
Check the Windows Device Manager. If there's a device with a yellow exclamation point, try removing it, disabling the cable, and plugging it back in. USB-Ports, especially to switch from ports USB 3.0 (blue) on USB 2.0 (black) as some older controllers work better with Android devices.
In rare cases, the conflict causes antivirus software or firewall. Try temporarily disabling third-party security programs. Also make sure that the smartphone itself is not on mode «USB-modem that can block access to the file system.
⚠️ Warning: If the computer makes a device connection sound but the driver is not installed, do not connect the phone to other PCs until you know the cause.
Alternative methods of data transmission
If the wired connection is dead or the cable is lost, there are effective wireless methods, and the built-in Mi Share feature allows you to transfer files to Windows computers over Wi-Fi without installing additional software, working on the principle of AirDrop.
You can also use FTP. The standard Explorer app on Xiaomi has a Remote Control feature, and when you run it, you will get an address (e.g., ftp://192.168.1.5:2121) that you need to enter into the address bar of any conductor on a computer on the same Wi-Fi network.
For large amounts of data, cloud storage like Google Drive or Xiaomi Cloud is also a handy option, although it requires a stable internet connection.Folder syncs occur automatically in the background, allowing files to be accessed from any device.
