Patches wont work, SEUS wont update

Hi, I am not new to Flashing and have flashed my w580i a couple of times to install patches and elves. But now I face a problem, the thing is SEUS(sony ericsson update service) wont update my phone. It would recognize my phone & then skip the installation part & move to the "Finished" section saying "Your Already has the latest software instlled."

Well, I wanted to update my phone because now even after flashing my phone's MAIN & FS files & following this tutorial... I phone will not allow patches to work. But,however some patches like bluetooth name patch, Privacy patch do work but patches like "showing the IFS in the file manager" & "to freely move any sorta file anywhere in my phone" & "to edit the extention of the file name" wont wwork. Absolutely no effect.

so, plz help me!
