    An unknown error 3194
    Modify C:\Windows\System32\drivers\etc\hosts, you can use Notepad to open.
    Option One: Add 74.208.10.249 gs.apple.com inside
    Option Two: Add #74.208.10.249 gs.apple.com inside
    Option Three: Add the following content inside

    # Copyright (c) 1993-2009 Microsoft Corp.
    #
    # This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
    #
    # This file contains the mappings of IP addresses to host names. Each
    # entry should be kept on an individual line. The IP address should
    # be placed in the first column followed by the corresponding host name.
    # The IP address and the host name should be separated by at least one
    # space.
    #
    # Additionally, comments (such as these) may be inserted on individual
    # lines or following the machine name denoted by a ‘#’ symbol.
    #
    # For example:
    #
    # 102.54.94.97 rhino.acme.com # source server
    # 38.25.63.10 x.acme.com # x client host
    # localhost name resolution is handled within DNS itself.
    # 127.0.0.1 localhost
    # ::1 localhost
    Note: Win7 users may not modify because of a permissions issue, right click on “Properties” of hosts; select your current logged on user, click “Edit”. Select your current user, find the “right” and check all , click application, and then OK. To modify the hosts.

    These three cases can fix the error 1601, you can turn the test, until success, I have not met via these three plans still occur an error 1601.
    Modified complete, please restart the computer and iOS device.
