How to Install Android 5.1.1 YROM Custom ROM on Sony Xperia Z3

I have used Xperia Z2 for quite a good amount of time, it wasn’t mine but still i was able to get the max out of it. If I am to judge Xperia Z3 based on what I saw in Xperia Z2, I can pretty much expect a good device. Even on the Stock ROM with all the bloats and other stuff, Xperia Z3 will perform quite fast and smooth. With the help of a custom ROM you can groom that device even more and make it works even faster than usual.

Any Custom ROM based on Android 5.1.1 will work quite better than Marshmallow and we have the best possible Lollipop based ROM for you.
