Rather than searching for isolated, sketchy .inf files on third-party forums, look for the official (often distributed inside official OEM flashing tools like Xiaomi's Mi Flash Tool or official Qualcomm SDKs).

Without the correctly installed driver, the PC sees an unknown device, and the flashing tool cannot detect the phone, making recovery impossible. When the driver is correctly installed, the device in Device Manager changes from the cryptic "QUSB_BULK_CID" to a recognizable device like "Qualcomm HS-USB QDLoader 9008" (commonly referred to as the "9008 port").
