Sony Xperia Z3 and Z3 compact received the Lollipop update recently by Sony and the latest firmware version is 23.1.A.0.726 with Android Lollipop 5.0.2. Rooting any Xperia device is very simple as you can easily unlock its bootloader but these devices do not come with a dedicated recovery partition, so the boot image is modified to fit in a custom recovery but the boot images are firmware dependent.

But you can get root access and pre-installed recovery on it with the pre-rooted ROMs. Thanks to welshlad (senior XDA member) for providing a flashable stock Android 5.0.2 firmware file (without installing any root file), which is pre-rooted and has dual-recovery installed.
