    To those getting error 3194:
    Go to Windows/sys32/drivers/etc and look for the host file. Open with notepad and copy this:

    Copy and paste what's below to the open host file with notepad and remember to delete all before that it has.


    # Copyright (c) 1993-1999 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
    74.208.10.249 gs.apple.com


    But you have to erase the other stuff first. So essentially it should be already the same thing. I don't know why this worked particularly, but it did. Mostly I guess b/c my host file was a mess.

    Save and close. Restart Itunes and shift + restore and choose the 4.0 IPSW. You might have to restart the whole process over, but it DID work for me. I hope it works for you guys.
    I did this w/ 8gb touch mc model 3g using the 2g firmware. I did the part 2 of the tut and it worked just fine.

    This does not work for the 2G MC MODEL! It will give you a Waiting for iBSS or a Preparing ipod to restore forever looping message.
