Although no one can buy Xperia Z Ultra but on XDA developers have owned many models are then shared copies of the original FW for other programmers to create a mod delivery area as well as applications for other Xperia models.
The minimum requirement is that you must have the form Xperia HD resolution of 1280 * 720 or higher, have root and running Android 4.1.2 or higher. Basically the new version of this mod is developed, mostly works well but could not avoid a few nasty bugs. You should consider them before installing. The models with lower resolution is to wait for the mod after temporary or download Wallpaper for ground support.
