USB Connection Mode: Why Xiaomi is Not Going to File Transfer Mode

Xiaomi's default mode is Charge Only when connecting to a PC, and to transfer files, you need to manually switch to MTP (Media Transfer Protocol) or PTP (for photos), and if you don't, the computer won't see the phone's internal memory.

How to change the regime:

  1. Connect the phone to the PC.
  2. Unlock the Xiaomi screen (important!).
  3. Swipe down the notification panel.
  4. Click on the notification “Charging through” USB» (or «USB-connection»).
  5. Select File Transfer (MTP) or Photo Transfer (PTP).

If no notice appears:

  • 🔧 Go to Settings. → Connections and sharing → USB and select the mode manually.
  • 🔄 Reboot your phone and reconnect.
  • 📱 On some firmware (for example, MIUI 14 for the global version) you must first allow debugging by USB (see next section).

💡

If you connect Xiaomi to a Mac, MTP mode may not work due to macOS features. Use PTP or special programs like Android File Transfer.

⚠️ Attention: On phones with unlocked bootloader (for example, after firmware custom recovery) mode MTP It can be unstable, and then it's going to help you to reflash the official one. MIUI via Fastboot.

3. USB debugging and hidden developer settings

How to enable debugging by USB:

  1. Activate Developer Mode: Go to Settings → About Phone. Click 7 times on the MIUI Version (you’ll see a message saying “You’re a developer!”).
