Step 3: Install manually via Device Manager (for “SPRD U2S Diag” with yellow exclamation mark)

1. Press Win + X → Device Manager
2. Locate the device – usually under Other devices or Ports (COM & LPT) as “SPRD U2S Diag” with yellow triangle
3. Right-click → Update driver → Browse my computer for drivers
4. Point to the folder containing the extracted driver (look for .inf files like spd_usb.inf or u2s_diag.inf)
5. Click Next – if warned about unsigned driver, choose Install anyway

Troubleshooting "COM 22" Issues

• Driver Signature Error: If you are on Windows 10 or 11 and the driver fails to install, you may need to disable Driver Signature Enforcement before running the installer (Advanced Startup Options).
• Wrong Port Number: If your software requires a specific COM port (e.g., COM 1 to COM 10) but your PC assigned COM 22, go to Device Manager > Right-click the device > Properties > Port Settings > Advanced > Change the COM Port Number manually.
• Bad Cable: If the connection keeps dropping, try a different USB cable. Diag mode requires a stable data connection.
