Code:
I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this ROM
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you. 
A lot.
Original Guide

Prerequisites
1.) Download LG Root
2.) Download LG Drivers
3.) A micro USB cable connected to your PC
4.) Your device must be unencrypted
5.) Before you ask a question, make sure you looked at the pictures in the guide.


1.) Download and unzip the LG_Root.zip in your preferred location


I chose the Desktop for my location




2.) Enable ADB debugging on your device

Go to Settings > About Phone > Software Information and tap build number until you are presented with "You are now a developer"
Exit back to Settings main screen
In Developer Options enable USB Debugging (Some devices require enabling PTP for debugging to work)



3.) In the root of LG_Root folder start a command prompt

Instructions may vary based on Window's version
Inside of LG_Root folder hold shift and right click a blank space you should see "Open command window here"






4.) Now that we have a command prompt running in the root of the folder let's get started. (Commands are copy+paste unless specified)

Let's make sure our device is connected
Code:
adb.exe devices


5.) Great! My device is connected let's continue, we need to get the files onto the device used for this root method.

In the same command prompt let's execute another command

Code:
adb.exe push busybox /data/local/tmp/ && adb.exe push lg_root.sh /data/local/tmp && adb.exe push UPDATE-SuperSU-v2.46.zip /data/local/tmp


6.) Well that was easy , let's continue (Now that we have the files on our device we want to put our device is download mode)

(Note this method may vary from device to device)
Power off your device
When the device is powered off, hold volume up and insert a USB cable connected to the PC
Wait for the drivers to install


7.) We're almost done (you've managed to get in download mode)



8.) Let's find which COM port our device is connected to

Double click ports.bat (This will give us the COM port in which our device is connected we are looking for the Diag port)

You may exit this command prompt when you have your COM port number, keep the other command prompt open





9.) Let's Begin! (Keep the device in Download mode)

Let's run Send_Command.exe (It couldn't connect? Make sure you COM port number is correct it varies)
Code:
Send_Command.exe \\.\COM4



10.) Final Step!!!!!! (We must run the root script)

Code:
sh /data/local/tmp/lg_root.sh dummy 1 /data/local/tmp/UPDATE-SuperSU-v2.46.zip /data/local/tmp/busybox




11.) We're done

You may pull the battery to get the device out of Download mode

Devices confirmed working with root method (If your device isn't listed it's most likely still supported)
  • LG F60 (all variants)
  • LG Tribute (all variants)
  • LG G2 (all variants)
  • LG MS395/D393
  • LG G3 (all variants)
  • LG L90 (all variants)
  • LG Transpyre
  • LG Volt (LS740)
  • LG G Flex 2

NOTE: Do not attempt this on devices with 5.1.1 , at the time this method was posted it worked on many firmware 5.0.2 and below. With the current releases from LG, this method has and will brick many users. This can be said for the one click method as well. Failure to read the complete thread may render your device non repairable as the KDZ firmware isn't released for all LG devices.

It works for some devices. It has yet to be confirmed. The confirmed devices are for root only.

After zeroing out the LAF partition the boot loader falls back to fastboot the LAF partition is simply LG's Download mode. Once it falls back to fastboot you can run fastboot commands , but nothing is being replaced it existed it was just a priority LAF over fastboot. If fastboot was removed by LG in your device it wouldn't be replaced.

yes I understand laf and the ends and outs,what I'm saying is fastboot was removed on the Verizon g3 so if I remove laf there will be no fastboot.just confirming this can't replace fastboot that was removed

I guess I should warn people about that thanks, hopefully someone can find a workaround for the secure boot.

Ya definitely ,I know better but guy above may have already gone down that road.Would be nice to replace it somehow..The users may not realize Verizon is the only g3 with no fastboot and removing laf can be very dangerous..
