I just got my Z3c over the weekend, and since it was working perfectly on AT&T with LP 5.0.2 I was reluctant to do the whole downgrade/unock/relock/root/flash/upgrade/etc. root method.
Fortunately the latest version of Kingroot will root the phone with OTA Lollipop upgrade working and unlocked bootloader. I have 23.1.A.1.28 rooted without even having to enable ADB or do anything but install and run the Kingroot app.
EDIT: Editing here by request on this thread. There is another thread on this forum dealing with Kingroot in detail. Some suggest that the Kinguser app transmits the phone's IMEI and this introduces some risk. For me, I managed to get rid of the Kinguser app and install SuperSU instead. My phone works fine, rooted, with SuperSU (which was installed via recovery/flash method). I have no comment about how risky Kinguser app is, whether anyone is trying to steal something from you, or what your risk level might be with Kingroot method. Buyer beware.
I would say, if Kingroot can do this without the downgrade/unlock/relock/upgrade method then so can non-KR devs.
