Primary Causes of the Handshaking Error

To fix the problem, identify your symptom first: The digital silence of the workshop was broken

Step 6: Try Different COM Port

8. Advanced steps (for experienced users)

• Inspect Device Manager while connecting to see the exact driver behavior and error code.
• Use a serial terminal or tools like "MTK Droid Tools" to watch port activity.
• Reflash preloader firmware only if you have the exact preloader binary and understand risks — flashing wrong preloader can brick the device.
• For intermittent connection, try shorting test points (if documented for the device) to force preloader mode — do this only with hardware experience.
