USB-cable to wireless protocols, and solve typical driver problems, MTP authorization.
Redmi Note 7 (codename lavender) features in its Qualcomm Snapdragon 660-based hardware platform, which requires specific drivers to work correctly with the PC. In addition, the manufacturer often updates the MIUI firmware, which can affect data transfer protocols. We took into account all the nuances and prepared instructions that are relevant for all versions of MIUI (including global and Chinese) and Windows 10/11, macOS and Linux operating systems.
1. Connection through USB-cable: basic method
The most reliable and quick way is to use the original USB Type-C cable that came with the phone, but even here there are pitfalls: cheap uncertified cables may not support data transfer (charging only), and USB 3.0 ports on a PC sometimes conflict with the MTP (Media Transfer Protocol).

- 🖥️ Connect to the port. USB 2.0 (usually black) - it is more stable for the MTP, blue-port USB 3.0.
- 📱 On the phone when connecting, select File Transfer mode (MTP) notice "USB For....” If the notification does not appear, check the developer settings (more on this below).
If the computer can't see the phone,

Once you activate USB Debugging, you will receive an authorization request when you connect to your PC — be sure to confirm it by ticking the “Always Allow from this computer” box. Without this, many functions (such as ADB or Fastboot) will not work.

Method 1: FTP-server (for experienced users)

5. Solving common mistakes
Even with the right connection, the Redmi Note 7 can refuse to interact with a PC.
| Mistake. | Reason. | Decision |
