The handshake error you're experiencing is happening at the preloader/BROM connection stage, before the DA is loaded (my changes fix the DA handshake that happens later). Quick Fix Steps:
Root cause: Device isn't entering BROM mode properly. The "Handshake failed" message means mtkclient can't establish initial USB communication with the bootrom. This happens before any DA loading or my protocol fixes are involved. Note: My changes fixed the DA handshake (READY vs 0xC0), which happens after successful BROM connection and DA upload. You're not reaching that stage yet.
The handshake failure is a BROM/Preloader connection issue, not related to the DA handshake fix in this PR. Quick Fix: Remove the Use this instead: python mtk.py gettargetconfig --loader .\mtkclient\Loader\DA_A15_lamu_FORBID_SIGNED.bin --ptype kamakiri2 --preloader .\mtkclient\Loader\Preloader\preloader_lamu.binOr without preloader: python mtk.py gettargetconfig --loader .\mtkclient\Loader\DA_A15_lamu_FORBID_SIGNED.bin --ptype kamakiri2Complete troubleshooting guide: See
The handshake must succeed before the DA agent is loaded, so this is a device connection issue, not a protocol issue. |

@copilot es posible usar directamente el puerto com sin usbdk |
Sí, es posible usar el puerto COM directamente sin UsbDk usando el parámetro Usando puerto COM (sin UsbDk): # Auto-detectar puerto COM
python mtk.py gettargetconfig --serialport
# O especificar puerto manualmente
python mtk.py gettargetconfig --serialport COM3Diferencias importantes:
Limitaciones del modo Serial:
Para tu caso MT6768 Lamu: # Intentar con puerto COM
python mtk.py gettargetconfig --serialport --loader DA_A15_lamu_FORBID_SIGNED.bin
# Si el dispositivo no responde, debes usar UsbDk (modo USB)
# porque probablemente estás en BROM modeEl modo serial es útil principalmente para dispositivos más antiguos o cuando tienes problemas con UsbDk, pero para operaciones completas (exploits, lectura/escritura flash) es mejor usar UsbDk con conexión USB directa.
Sí, mtkclient ya soporta conexión directa por puerto COM sin necesidad de UsbDk. Usar SerialLib (puerto COM directo): # Especificar el puerto COM directamente
python mtk.py gettargetconfig --serialport COM3
# O en Linux/macOS
python mtk.py gettargetconfig --serialport /dev/ttyUSB0mtkclient detecta automáticamente si usar USB o Serial:
Ventajas del puerto COM:
