This has been proven to work with lots of genuine users from a very reputable torrent site which i use often and it seems this release is deff what everyone wants. Its tested and proven effective from a 2.0 to a 1.5 fw conversion downgrader. I hope this makes people a bit more relieved that something has finally come to shine on us all.
