| Symptom | Likely Cause | Solution |
|---------|--------------|----------|
| Device shows "Unknown USB device" | Corrupt driver or power cycle | Reinstall driver, use a different USB port, restart PC. |
| QFIL fails with "Sahara protocol error" | Incorrect driver version for EDL | Use only QDLoader 9008, not Diag port. Try version 1.4.08 specifically. |
| Driver installs but no COM port appears | Device not in correct mode | Enter EDL mode by shorting test points or using EDL cable. |
| Windows refuses to install *.sys file | Driver signature enforcement | Disable signature enforcement as described above. |
| Port appears but disconnects after 10 seconds | Loose USB connection or power saving | Disable USB selective suspend in Power Options > Advanced. |
