I have a Verizon branded Nexus 6...I unlocked the boot loader with TWRP (Just to get the tap to unlock feature). I never rooted the phone however. I just received the 5.1.1 OTA update. How do I go about installing this? Is there a way to do it through TWRP? I see the update.zip in /cache, FWIW. Any help would be greatly appreciated. Thanks in advance.
