On method Two I had the same problem what you need to do is first make sure the you burn the download from here http://www.megaupload.com/?d=4T5MBJL7
onto a cd as an Image try roxio they shoud have something there that says burn an Image cd or something like that next when you turn on your z2 wait till it loads press the map button press ok on the disclamer and then insert your cd. That should do the trick.
