Using the ADB and Fastboot command (platform-tools), you’ll be able to boot your Android device into the bootloader mode (download mode), which will be easy for you to proceed with further steps. ADB (Android Debug Bridge) creates a connection or bridge between the device and computer to sideload files.
Fastboot is a more advanced command utility tool for Android devices that works with computers. You can download ADB and Fastboot Binaries (Platform-Tools).
Download Xiaomi USB Drivers
A USB Driver is a set of files that allows you to create a successful and strong connection between a mobile device with a computer properly using a USB data cable. It’ll be useful to transfer files between the connected devices, flash files on the handset, and more.
It’s also worth mentioning that mobile devices and other external devices can use and run USB Drivers on a Windows computer. Such as a mouse, keyboard, printer, external hard drives, speakers, USB flash drives, etc. You can grab Xiaomi USB Drivers here.
