Root Xperia Z Ultra after Lollipop update 14.5.A.0.242


With the New Ansdroid OS, Sony released the Android 5.0 Lollipop update for the Xperia Z Ultra, fondly called XZU, a few days back. If you accepted the OTA, it meant your device was upgraded to Lollipop but you lost root access. Well, we’re sure you’d want to root your Xperia Z Ultra back, on Lollipop, and the good news is that you achieve that easily.

Using the Doomlord’s famous DooMKernel, you can boot into TWRP recovery and root your device effortlessly. Check out below.

This method was tested on the Lollipop update version 14.5.A.0.242, on model no. C6802. It could work very well on other models of Z Ultra, but not GPe edition of the device because it has different variant of DooMKernel.
