I've saw a lot of these posts and I also had the same Issue.
first of all I'm not taking any responsible for this, but it worked for me so.. you can at least try if you have no option left.
please note thatYOU WILL LOSE EVERYTHING on the internal storage of your LG G3!
IF YOU DON'T HAVE ACCESS TO DOWNLOAD MODE :
Please get yourself the right LAF file for your phone and insert it into the adb.exe and the fastboot.exe folder (if you don't know what I talk about please download Android SDK platform)
press Ctrl+Shift and right click inside the folder and choose Open Command window here (http://img5013.photobox.co.uk/11895...2cd987792512dcafe1c9acf628a3ef5b3a604bc5f.jpg)
Now at the CMD window that opened Type :
fastboot erase recovery
PLESAE MAKE SURE YOU DOWNLOADED THE RIGHT LAF FILE FOR YOUR PHONE before attempting this (at the same android version)
fastboot erase laf
fastboot flash laf laf.img
If you can't find the LAF file for your phone you'll have to Extract it from the KDZ file using this Tool http://forum.xda-developers.com/showthread.php?t=2600575
Now you can accesses the download mode by restarting the phone.
Take the battery and the Sync cable out
while pressing the +Vol button insert the battery and the cable while continuing holding it


IF YOU HAVE ACCESS TO DOWNLOAD MODE :

Please download the TOT and .Dll files specifically for your phone from here: http://downloadandroidfiles.org/Files/LG G3/Stock Files/

after that follow this video and you're all good :

Hi Mate, It's not noobie at all.
You need to download the Android Debug Bridge (ADB) from this Link :http://developer.android.com/sdk/index.html
Ticket the platform-tools you don't need the rest
Or you can have the easy way and Download it from here: http://forum.xda-developers.com/showthread.php?t=2588979

Or maybe you don't know where are the specific folder in which case go to where you installed it. mine is at C:\Users\Sahar\platform-tools

And on the way download the LG G3 drivers from LG download center or from this link: http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425

@SaharLevi
Here's the fix Quick and easy
need to have fastboot, I used ubuntu can install with sudo apt-get install android-tools-fastboot
info on fastboot
[TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer
also need recovery.img, I used the lastest twrp

In terminal
fastboot boot recovery.img

this will boot your phone with the img on your computer.

in recovery restore or install a good boot or kernel.
your phone should be good to go after that.
I had my phone fixed in about 5 min, I really should not play around with boot partition.

Also should be able to flash boot if you have a good one,
fastboot flash boot boot.img

I have a weird problem, i'm in fastboot, and my laptop sees the phone, but none of the fastboot commands work. They get echoed on the screen and appear to be working but they don't do anything. I've tried flashing, rebooting... pretty much everything, and nothing happens.

I navigate into a folder with all my img files and then tried a few things:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot boot boot.img
fastboot flash laf laf.img

I've also tried to erase a few times, and even reboot, and nothing happens, even though it says on the lg screen that it's rebooting.

try

adb fastboot flash recovery [located recovery file]
or
./adb fastboot flash recovery [located recovery file]

I'm assuming you meant just fastboot, adb fastboot just prints out help.

It says:
Code:
target reported max download size of 2147483648 bytes
sending 'recovery' (11496 KB)...
OKAY [  0.362s]
writing 'recovery'...
and on the phone it says [7164300] fastboot: flash:recovery
But nothing happens. It's as if fastboot is broken.

Type from folder with recovery.img

fastboot boot recovery.img

if it a bumped recovery, it should boot into recovery. Then you should be able to restore a backup

I've tried that, i think my fastboot is somehow corrupt, i guess i have a hard-brick, i hope LG will replace it.

Thanks for your help
