Sometimes it might have happened to you that you have erased your download mode while doing some fun with adb commands and enjoying android development with starter knowledge. In this process you unfortunately destroyed your download mode.
Now you want to go back to stock but your download mode is not appearing only a fastboot mode opening saying some very tensed and confusing things to understands. This is the situation where you are totally messed up and out of mind. Don't know what to do. Tried whole of internet and can't find a solution. Now method is working and you want a fix. Then this thread is gonna help you a lot. You will be very happy to read instructions here cause they are easy and also phone saving too. These instructions can even save your amount to be given to a repairing shop.
So a lot of introduction is done, let's proceed to the process. First of all read disclaimer to avoid any misunderstandings of future.
Code:
Your warranty is void now. I am not responsible for any mistake and wrong thing happens to your device. Always try if you have a good knowledge of that.
These steps are not an official LG  and therefore not endorsed by LG Electronics in any way. As such, this is a 'try-at-your-own-risk' approach. Please make sure to back up your important files when trying this for the first time. I take no responsibility for any undue outcomes resulting from the use of these steps and instructions. And all the best for step.
Things you Need:
1: LG united mobile drivers here. (Skip you have already)
2: adb & Fastboot drivers from here. (To do flashing commands). Minimal Edition.
3: Make sure "USB debugging" is on for you LG G3 device. If not sure check here.
4: laf.img for your device . (Download mode image). Most important thing
Download it from here according to your device variant like as d850, d855 or etc.
Select your variant > Stock partitions > 10D > laf.img ( I prefer 10d laf.img you are welcome to try other ).
5: LG G3 device in fastboot mode by connecting to PC while phone is powered off pressing volume up(+) button.
6: And the most important thing a computer. (I tried it on Windows 10 but will work on 7,8 and others too.

Steps:
1: Install LG united mobile drivers.
2: Install "adb and fastboot mode" drivers. Copy "laf.img" to the directory where you installed them and run "MAF32.exe"
Mine is "C:\Program Files (x86)\Minimal ADB and Fastboot"
3: Connect your LG G3 device while in fastboot mode.(Make sure drivers are installed).
4: Check if connection is right by doing this command
Code:
 fastboot devices
5: If you done right your device might appear. (Sometimes as a question mark too)
6: To flash download mode. Execute these commands in sequence.(Make sure "laf.img" is copied to that folder where you installed the adb and fastboot drivers and is named as "laf.img").
Code:
fastboot erase laf
fastboot flash laf laf.img
fastboot reboot
7: Pull battery of your device and reboot into download mode again if flashing is successful. Download mode might appear as original. If not then you might have not listened to instructions. (If still stuck ask in comments).
If i helped you anyhow press "Thanks"
All the best with process.

Proper fixes
1: Turn on usb debugging.
2: Install driver again or try the procedure on some other computer
(If you can get a computer running Windows 7 32-bit that would be a good choice)

Fastboot doesnt work
Hi there

I hardbricked my phone while reinstalling stock rom when my laptop crashed. Afterwards adb and download mode wouldn't start, only thing now is fastboot.
I tried your solution, but it doesn't seems to be working. The device is showing in CMD (fastboot devices) but further commands arent accepted, they show up at the G3 screen, but afterwards nothing happens. What can i do (I really don't want to try the "short-circut - Qualcom" method).

Drivers and so on are properly installed

Thanks in advance

Can't get to download mode!
I did everything as instructed and the flashing was successful...
But whenever I want to go to download mode, it just shows download mode icon and then goes straight to fastboot!

How can I fix this?

booting to download mode
in adb type

PHP Code:
adb reboot bootloader 
this should get you to download mode......
if you try
PHP Code:
adb reboot fastboot 
or VOL UP+USB
you cannot enter download mode
if you are on a custom rom.
The phone will just reboot.

However
PHP Code:
adb reboot bootloader 
seems to do the trick.

Also I am on LG G3 D858HK with mokee rom 7.1
and this works for me.
