Rooting a G2 with the LP firmware still possible.

I love my G2 so much because of the current ROM i am using and for what I use my phone for, I really don't need anything better. The problem is I fool with it so much I am concerned about it wearing out or breaking so I want to buy a backup G2 in case something happens. I imagine a new or used one would problably come with the latest firmware (5.01 or 5.1.1) and I am concerned about being able to root it. It's been so long since I rooted my phone (I think I used ioroot originally) and I haven't kept up with newer root methods so I don't know if they work with the latest firmware or has Verizon closed that door.

Is there still a way to root a G2 VS980 if it comes preinstalled with the latest lollipop updates from Verizon?

I searched through the forums but can't seem to find a definitive answer. Thanks for any advice...
