ok, i saw this post
[SOLVED] does anyone have k850 startup screen???? - Top Sony Forums
and i thought , it would be cool to have that, so i downloaded the settings file, and didnt know where to put it, so i used XS++, fsx, went around random folders, and decided to put it in this foler
"/tpa/preset/system/settings/"

but now, when i turn my phone on, there is no start up screen (same with when i turn my phone off, no shut down screen) =\ help anyone?
