Do u have a bunch of flash menus (.swf) without themes (.thm) , then this is the right place you've come.
Tools required :
Tugzip: Download
Some themes: Download
Step1: Download some themes compatible for your phones.
Step2: Now in pc click start, select control panel, and select folder options and then view.
Now untick the box "Hide extensions for know file types." By doing this we can change file extensions.
Step3: Now rename themes (.thm) to (.tar)
For EG: Like orbit.thm to orbit.tar
Step4: Now u open .tar with Tugzip and u will see bunch of icons alongwith "Themes.xml"
Extract those icons alongwith "Themes.xml" in a folder.
Step5:Now open "Themes.xml" with note pad.
Now below this line : <Sony_Ericsson_theme version="4.7">
Add this line :<Desktop_style Type="File" Source="custom.swf"/>
Note : Here .swf represents your swf file.
For eg : <Desktop_style Type="File" Source="Neon lights.swf"/>
Be careful here and put the corresponding name of .swf exactly as it is otherwise it won't work.
Then close and save it.
Step6: Now right click that folder (folder where icons are extracted and .xml edited) and click " Add to" tar back.
And rename the tar to corresponding .thm
Thats it now u have theme associated with a flash menu!!
