To update to VC, most people are following the instructions in the unroot thread:The phone in question is already rooted.
Do I need to unroot it for the update as it attempted to update once before but failed showing the yellow exclamation point.
Thanks again

Then once they have VC (via LG Software Updater) they are rooting with the new root instructions for VC here:

Depending on what you have installed, there could be other ways you can get to VC in fewer steps but I'd only suggest pursuing that if you know what you are doing.
For example, if you have stock V9 installed along with stock recovery, you could just run the LG Software Updater to get VC.
