hey guys, just recently purchased SE W350a :)
wanted to tamper with it and well as unbrand it so i can use music files as ringtones...
so i downloaded the update service from the Sony web and also XS++

Upon opening XS++ and following the procedure this is what it said:
16:34:48| XS++ v3.1 (Darwin) Ready !

16:34:48| Executed on Microsoft Windows XP

16:34:54|

16:34:54| Attempting to open the interface...

16:34:54|

16:34:54| TURN OFF PHONE!

16:34:54| Hold 'C' button on phone and connect phone NOW.

16:34:54| You have 30 seconds...

16:34:54|

16:35:24| Error: Cannot open phone communication port

16:35:26| Disconnected... Unplug the phone

16:35:30| Shutting down...

I've tried connecting it as the tutorial states and the outcome is always the one above.. any sugeestions?
