I just got the SGS2 today and am trying to connect with Odin, however the drivers won't install and the ones I got from Samsung's site aren't working. If it helps I'm using a virtual win 7 on a Mac.
I got the drivers working now, but when I try to upload recovery with odin, Odin crashesI was able to get the correct drivers by installing the Kies software. You should be able to find it doing a search.
