You can even log in and ask for firmware and search for firmware, here's how:-

You don't need to pay, but you get "coins" when you post a useful message, there is an English language section where you can ask for firmware and "cheegi" will help.
You will get some free "coins" when you register, which should give you about 5 downloads, so use them wisely.
