4.4.4 theme engine on 4.4.2

Hi,
is there a guide how to get 4.4.4 theme engine on 4.4.2 ROM's. I tried replacing the secthemechooser from a 4.4.4 based ROM but it still does not pick up the 4.4.4 based themes.

Thks in advance.

Can the CM12 theme engine be ported to stock firmware alone?

Guys,

Recently, I am struggling between using cm12.1 and stock .222 firmware foe my Z because they both have something I desire ( system ui and camera for .222 and cm theme engine for cm12 ). My question is can they exist on my phone at the same time? If so, what ROMs or addons should I apply to my phone?

Many thanks!
(Sorry for my poor English)

Samsung Theme Engine

Are there any guides on how to make themes for the Samsung theme engine ?
Or a software to create themes for it?

Bravia engine after bootloader unlock!

So as the title reveals, I have unlocked the BL and tried a few custom roms. Didnt liked any so back to stock. But i just came to know that we loose bravia engine after we unlock the BL. But as I m on stock 4.1.2 I do see the bravia engine on/off toggle. Its quite confusing. Have i really lost bravia engine? Or it just gets restored when we flash stock roms?
Well If i have lost my BE, any way to restore it back? i mean will locking the BL do?

thanks!
