Cheap cables have high resistance (over 2 ohms). The handshake signal requires stable 1.8V. A bad cable drops voltage below 1.4V, causing handshake failure. runtime
A: No. The MTK Bypass Tool requires a Windows PC. The handshake is a PC-to-phone protocol. Switch to a USB 2
| Symptom | Likely Cause | | :--- | :--- | | Tool says "Waiting for device" then "Handshake failed" | Driver conflict or wrong USB port | | Device connects, disconnects, reconnects rapidly | Broken preloader (boot loop) / battery voltage | | Error appears instantly after clicking "Bypass" | USB cable or motherboard short | | Works on USB 2.0 but not USB 3.0 | Power negotiation failure |
