Flash themes for w900i how to?!

Could you please tell me haw can i use flash themes on my w900? I know it's possible as youtube videos...
I tried every way at last the phone says: "the file is corrupted"
I'm really confused...
At first I have a .swf file and I try to uploadit with xs++ v3.1...Here is the first disaster, It does not work properly and when I use phone xs it says "brown phones are not supported"...
second disaster happens when I want to edit .thm files... the first thing is that theme for w850i may not work with w900i because of xml versions in them (4.1 for w900i and 4.5 for w850i).
Backstreet and Avenue themes with flash menue works on w900 as defult...
Even I edited backstreet theme and chenged only file name of .swf but again it dosent work and say what it say always : "the file is corrupted"
I think there is 2 problem one with xs++ and second with xml file...
about the second problem i have to say when I opened my edited theme in sonny erricson thme creator and error revealed about xml version and program told me that it will convert it to proper version, after that it worked on phone but without flash menu...
PLZ tell me anything U know about it
THNX

For now, u simply can't do it.

U'll need to get access to your phone's file system, in order to flash into it the command line for new menu linked to the correspondant theme.

So u have to wait like all of us the release of new xs that will be able to flash single files to file system.

Bye.

yeah no way to do it.. videos on youtube are maybe fake or they juust have a debranded phone with the original flash themes on it.

i want flash menu toooooooooo please help me :cry: and by the way i am new her
i thank all the members her for the good informations
