Hi mate! So far there are no any patches for X660. And i guess, won't be as X660 is a Agere model and as you may know Agere models are very hard to reverse. As for service codes, you can refer to this topic http://OldPh.one/index.php?showtopic=582 (but information there is in Russian ) It's better for you to ask here what exactly you need to get by means of service codes
