I think you have copied the swf to wrong place...
you have to copy it in FS/tpa/preset/system/desktop/flash/
now that your phone is dead....'cause you say it wont turn on,
the only way remains is to reflash your phone with another f/w.
dont directly reflash your phone,
but first try to access your phone's FS using FAR.
If you can access it then you might wish to make a backup of your data...
Reply your result..
then i will help you out.
