I also would like to patch an HT-F5500W, is there anything to do with F Series? or my destiny is to keep using my D series patched BRplayer for ever?

Thanks

Is it just source ip-addresses or is there some "authentication/signature" etc that is required to fool the device?
Perhaps you don't know...
