Verizon VS985 TWRP Boot error

I just rooted my second Verizon G3 that is running 24b. It took several tries to get it done but I finally got root. I then used Flashify to install TWRP. When I reboot into TWRP at the very top of the screen I get a secure boot error message that pops up. Then it goes to recovery and all works normally. When I reboot the system the G3 works fine. Just wondering why I am seeing this error.
I just rooted 2 other G3 phones last week bu they were still on 12b.

Vs985 kk roms...

So after a few months of being without my VS985 I am finally getting a new G3... I have a bunch of the KK ROMs that are no longer available for download for whatever reason on a number of my SD Cards- will be uploading to Mega and compiling a list if anyone is interested in KK Roms or needs assistance with anything G2/G3 related please PM me here or on hangouts derricklaub@gmail.com...

VS985 Can't Root on 5.0.1

:rolleyes::rolleyes:I've tried several different methods for rooting my phone and none of them have been successful.

they all say they're successful but I'm still unable to flash TWRP or do anything that requires root access. I've tried multiple times (each method) with different cables and after rebooting the computer multiple times as well.

I have the Verizon LG G3 (VS985) on Android 5.0.1
