    2. Hi Andy,
      The above error msg may cause by Android_Gadget_CDC_driver, after I tried to connect it alerted for CDC driver so I installed it and work now.

      I want to know whether it works for Asus Zenfones or not since I browsed via ROOT explore I cannot find MDDB in phone system as I did on Lenovo.

      Could you please advise for any other brand such as Sony Ericsson, Samsung, ASUS Zenfones, etc. Does it work for these models?

      Thanks for your sharing!

    3. no you don't need root. Only need meta mode on your device.
      if you cannot connect it then try again and again connect your device and go to meta mode. first time will be hard but once you can get to meta mode it will easy for you

      Delete
    4. ok, i already see the video, and i think it not on meta mode. because on meta mode your device not known as Lenovo S660 but known as PORT. so it will not show as windows icon. Turn off your device with battery, then connect wait until charger icon disappear then press power button, exact 2 second release power button and your device will be on META mode

    1. wipe system if you install using recovery mode, or flash using zip method.
      if you flash using flash tool that no need to wipe the system or format the system, it automatically wipe by flash tool.
      the result is same wipe or not.
