XS++ 3.1 Guide-Flashing, Customizing, Recovering

[FatalSTK]

hey
I have already flashed my phone (W580i) before but had to use the master reset (cant remember y) but then the flash menus and walkman themes got deleted and i tried to get stuff back again but it wouldn't detect the phone
so i tried to flash it again but when i hit the flash button i get this:

22:41:01| Ready for operation!

22:41:05| After making any changes with FSX

22:41:05| you must press the 'Shutdown' button

22:41:07| Sorry, your phone is NOT SUPPORTED

22:41:07| Error: FSX failed.

22:41:07| FSX Shutdown!

22:41:09| Disconnected... Unplug the phone

22:41:19| Shutting down...


can it only be flashed once , or does anyone have any idea why it doesnt wanna flash anymore?
