The thing is XS++ didn't upload any file to your phone,so if you still want to upload flash theme to your phone start XS -> FSX and when XS make your directory tree navigate by yourself to "tpa/preset/custom/desktop/system/flash/ and put .swf files here,than go to
tpa/user/theme/ .thm files here. Use drag'ndrop system to do that and after that click shutdown FSX,pull batery out for few seconds,put it back and turn phone on
