  • TDK

    When you connect the 4n and press volume up key, The driver instalation starts but @ last it says Driver installation fail.

    And how exactly can the driver instalation location be directed to the “usb driver” folder?

  • ragNoz

    to Install the driver u have to copy

    ; SonyEricsson
    %SingleAdbInterface% = USB_Install, USBVID_0FCE&PID_0DDE
    %CompositeAdbInterface% = USB_Install, USBVID_0FCE&PID_0DDE&MI_01
    %SingleBootLoaderInterface% = USB_Install, USBVID_0FCE&PID_0DDE

    under the [Google.NTamd64] section in the .inf data. Then it will works on a x64 System. Otherwise you cant install the Driver. This is my experience.

    To resolve your issue, follow these steps:
    1) Open Device manager on your computer
    2) Connect the phone and quickly choose to change driver
    3) Disconnect the phone again (because it goes into normal mode).
    4) Choose to install a driver from the computer, choose “All devices” and “have disk”.
    5) Browse to the folder with the .inf file contained inside it (usb_driver).
    6) Now, before clicking Next, connect the phone again and quickly hit Next.
    This will install all the required drivers..
