K810i, where's my Layout.xml file and how do I remove my operator logo?

I've seen a tutorial on here:

How to hide (remove) operator logo - Top Sony Forums

And it's basically mumbo jumbo to me, I've never modded a phone before so I don't know what exactly I need to do. Could someone help me out here? Send me in the right direction?

(Sorry if this is in the wrong forum)

you need to download from the download section and then upload after you had finished the modding to tpa/system/layout/
