There are other ways, you can try downloading them from some Russian sites, but I found that method to be a real pain. You can also try requesting a link to download the firmware on this forum, howardforums, se-nse forums, and others.
Another option you have is to use Wotanserver, though it costs $10. It's pretty much foolproof as long as u follow their explicit directions.
I personally don't know of any links to dl's, sorry :(
