      click on the one that says 2hfs its the largest of all 4 files in size, it should then show a folder, click that, you should then see the ipsw file needed as i just did this by luck. lol

      • iavra says:

        the hfs file is an apple format(from what I just learned), not functional in windows. Any advise on how to convert this format to a windows-friendly one? thanks.

        Nevermind! I just used the same 7zip program and it worked.

        double-click .hfs file INSIDE THE 7ZIP SOFTWARE to explore it further !
