[Guide] Install Xposed on LG G Flex 2

I want to start by saying please forgive me if this already exists on xda, I did search but didn't find.

I've seen this method on a couple of different sites so it's by no means mine but I don't know who to thank for it so I'll thank @Chainfire for Flashfire (and everything else he's done for all of us), @rovo89 for Xposed and @romracer for this specific version of Xposed.

This is so simple I thought it was too good to be true, but all you have to do is

1) Download;
Xposed v71 sdk22 for ARM64 from here
Xposed installer from here
And Flashfire from here

2) Install Xposed Installer and Flashfire

3) Open Flashfire (grant root access) - click the "+" in the bottom right - select "Flash ZIP or OTA" - browse to where you downloaded Xposed v71 sdk22 for ARM64 and select it - ignore the "Auto-mount" option and click the tick in the top right - scroll down and check that "Reboot" is set to "Normal" and click "Flash".

4) Wait for your device to reboot. BE PATIENT! Your screen will go black and it will take a while (possibly up to 30 minutes) so I recommend you put your phone on charge while you wait.

5) Enjoy Xposed!
