How can I get my rooted Moto G to install Lollipop?

[AC Question]

Rooted Moto G Cant install Lollipop Have unrooted using Super Su still no luck

Hi needed to root phone as had replacement screen and needed to disable proximity sensor as didn't work with screen.

Have i think unrooted phone , boot loader still unlocked - system will not install Lollipop.

Have tried searching for how to do - one suggestion was to unroot - this does not seem to work - maybe my phone is not unrooted or I am doing something silly.

Is Lollipop worthwhile ? If so what do i need to do ?

Thanks in advance
