Connecting a Xiaomi smartphone (including the Redmi and POCO lines) to a computer is a challenge that every user faces. Whether you want to transfer photos, install firmware through Fastboot, or simply manage files, the right connection ensures that there are no errors and data losses. However, many users face problems: the PC does not see the phone, drivers are not installed, or the device is defined as βunidentifiedβ.
In this article, we will look at all the current ways of connecting β from standard USB (MTP/PTP) to wireless protocols FTP/Wi-Fi Direct, as well as common errors and their solutions. Particular attention will be paid to the MIUI settings, which often block the connection by default. If you are using Xiaomi 13 Pro, Redmi Note 12 or older model like Mi 9T, instructions will be suitable for all versions of the firmware (including MIUI 14 and HyperOS).
1. Connection through USB: base-method (MTP/PTP)
The most common way to connect is via a USB-Type C cable (or Micro-USB for older models), Xiaomi uses MTP (Media Transfer Protocol) by default, which allows you to transfer files as a flash drive, but often there are problems with determining the device.
- π Connect your phone to your PC with the original cable (cheap cables may not support data transfers).
- π± On the phone screen, select File Transfer Mode (MTP) plug-in.
- π₯οΈ On PC, check that the device is defined in This computer (Windows) or Finder (macOS).
- π If the phone is not visible, restart both devices and reconnect.
If there's no MTP in the list of connection modes, it means that the developer mode is on, and it's forced to lock, to return the standard options:
- Go to Settings. β The phone.
- Click 7 times on the MIUI version to activate the developer mode.
- Back to Settings β Additionally. β For developers.
- Find the default USB configuration and select MTP.
β οΈ Note: On some models (e.g, POCO F5) When first connecting to a new PC, you need to allow debugging USB If the window doesn't show up, check if the developer mode is on.
2. Solve driver issues (Windows doesn't see Xiaomi)
About 40% of connection problems are due to the absence or incorrect operation of drivers. Windows often automatically installs universal MTP drivers that conflict with the MIUI firmware.
- π§ Remove current drivers: Open Device Manager β Find Xiaomi or ADB Interface β right-click β Remove the device.
- π₯ Download the official drivers from the Xiaomi website (Mi Phone Manager section).
- π Connect your phone in Fastboot mode (clip Volume Down) + Power when the phone is turned off) and wait for the driver installation.
- π οΈ Windows 11 may need to disable driver signature verification (via gpedit.msc).
| Mistake. | Reason. | Decision |
|---|---|---|
| Device not identified (Code 43) | Driver conflict or damaged cable | Remove the driver manually, reinstall the Mi PC Suite |
| MTP-device fails | Protocol failure on the phone | Reboot your phone, change mode to PTP and back |
| ADB does not see the device | USB debugging is not enabled | Activate debugging over USB in the developer settings |
| The phone is charging but not transmitting data. | The cable or port is damaged. | Try another USB 3.0 cable/port |
Critical error: If Qualcomm appears in Device Manager after connection HS-USB QDLoader 9008 is a sign of a "brick" (inoperable firmware). EDL-Mode with the Mi Flash Tool.
3. Connection via Wi-Fi (FTP/HTTP-server)
If there is no cable or port USB It's corrupted, you can transfer files wirelessly. Xiaomi supports built-in FTP-server HTTP-Web interface for accessing files. Instructions:
Connect your phone and PC to the same Wi-Fi network|Make sure there is enough charge on the phone (>30%)|Turn it off. VPN/proxy on both devices|Remember. IP-Phone address (in Wi-Fi settings)
-->
- Download the Mi File Manager app (if you have removed the standard one).
- Open the app β press... (menu) β FTP.
- Start the server and the address will appear as ftp://192.168.x.x:2221.
- On PC, open the Explorer β enter the address in the address bar β Enter the login/password (by default: anonymous/empty).
For HTTP-access (via browser):
- In Mi File Manager, select Web Access.
- Copy the link of http://192.168.x.x:8080.
- Open it in the browser on the PC - the file manager will open with the ability to download / download.
β οΈ Note: When transferring large files (>1 GB) Wi-Fi speed can drop to 2-5 MB / s. To accelerate, use 5 GHz network or connect via the Internet. USB-debugging (ADB).
4.Use of Mi PC Suite (official software from Xiaomi)
Mi PC Suite is a proprietary tool for managing Xiaomi devices from a computer, which allows you not only to transfer files, but also to install firmware, make backups and synchronize contacts.
Advantages of Mi PC Suite:
- π Automatic backup (including: SMS applications).
- π Updating the firmware without the risk of "bricking".
- π± Managing notifications and calls from PC.
- π‘οΈ Built-in virus testing (for APK-file).
How to connect:
- Install Mi PC Suite on PC.
- Connect your phone via USB (MTP or PTP mode).
- On the phone, allow access to the data (notification will appear).
- In the program, select the desired section (for example, Files or Backup).
π‘
If the Mi PC Suite doesnβt see the phone, try connecting in Fastboot mode (clip Volume Down + Power when the phone is off) and then restart the device to normal mode.
5. Connect via ADB and Fastboot (for advanced users)
The ADB (Android Debug Bridge) and Fastboot protocols are used to debug, unlock the bootloader or firmware custom recovery (such as TWRP).
Step 1: Install ADB-driver:
- Download the Google Platform Tools.
- Unpack the archive in the root of the C:\platform-tools disk.
- Add a path to the environment variables (or use the full path to adb.exe).
Step 2: Connect the phone:
adb devicesIf the device is not displayed, check:
- β Whether debugging is enabled USB (Settings β For developers).
- β Do you allow access to your phone (a window will appear with the phone) RSA-key).
- β Whether you use the original cable (cheap cables often don't support data transfer).
For entrance to Fastboot:
adb reboot bootloaderAfter that, you can stitch the device through the commands:
fastboot flash recovery twrp.img
fastboot reboot recoveryWhat if the ADB issues an error called "unauthorized"?
6. Alternative methods: cloud services and third-party applications
If standard methods do not work, you can use cloud services or specialized applications:
- βοΈ Xiaomi Cloud: Automatic synchronization of photos, contacts and notes. Access from PC via web interface.
- π Pushbullet or AirDroid: Transfer files and notifications over Wi-Fi.
- π LocalSend: A free alternative to AirDrop for transferring files between devices on the same network.
- πΎ Termux + SSH: For advanced users, access to phone files via the terminal.
Example of LocalSend settings:
- Install the application on your phone and PC from the official website.
- Connect both devices to the same Wi-Fi network.
- On your phone, select a file β Send β select a PC from the list.
- On the PC, confirm the file's acceptance.
π‘
Cloud services are convenient for backups, but are not suitable for transferring large files (>5GB) due to traffic and speed limitations.
7. Frequent errors and their solutions
Even with the right connection, there can be failures, and let's look at the typical problems and how to fix them:
| Problem. | Probable cause | Decision |
|---|---|---|
| Phone is connected, but files are not displayed | Failure MTP-protocol or damaged SD-map | Restart your phone, try another cable or USB 2.0 port |
| Constantly requesting permission to debug | Developer settings reset | Turn off and turn on the USB debugging again |
| Mi PC Suite does not see the device | Outdated version of the program or firewall blocking | Update Mi PC Suite, temporarily disable antivirus |
| When connected, the phone starts charging, but the PC does not see it. | Cable damaged (power only, no data transmission) | Use a cable from the kit or a certified USB-IF |
| Mistake "USB-Device not "identified" in Windows | Driver conflict or lack of power on USB-port | Connect to USB 3.0 port (blue connector) or use a powered hub |
β οΈ Note: Xiaomi models with HyperOS (e.g. Xiaomi 14) may require additional permission to access files via Settings β Privacy β Special permits β USB-installation.
