Windows 10 and 11 often block these drivers because they lack a digital signature. Open (Run as Administrator). Type: bcdedit /set testsigning on and press Enter.

Verify device state

Windows 10/11 frequently overwrites the correct Qualcomm drivers with generic Microsoft ones. You will see error code or Code 28 . The "Fix" involves disabling driver signature enforcement and manually installing specific OPPO/Vivo signed drivers.

To fix the issue for Oppo and Vivo devices, you must install the Qualcomm HS-USB QDLoader 9008

Windows lacks the correct signed driver, or the system forces a generic USB driver over the Qualcomm port.
