Hi Guy I'm namterai2003 from XDA . Today I share you the Xperia ROM 4.4.4 and 5.1.1 for Samsung GT-S7580/S7582. 
Enjoy it!
The reason for beign CM based and not stock based is because we have not being able to port the Xperia functions the ROM includes to stock firmware. However stability is decent.
Features
Rooted | Xperia Z5 SystemUI | Xperia Framework | Xperia Phonebook & Dialer
Xperia Small Apps | Xperia Apps | Xperia Cameras | Zipalling
Xperia Interface | Xperia Widgets | Xperia Z5 Bootanimation | Sony Bootlogo
