Right now I'm following a guide to unbrick an Optimus G. Downloading the FW is the first step. It doesn't seem so difficult. If I manage to unbrick it, I will share step-by-step guide here.
I'm f***ed up! Nothing works. Who can help me really I want to kill myself.

While pressing both volume up/down together, connect your phone to pc via usb. Open LG Mobile Support Tool. From options, choose upgrade recovery.

As I recall, last time I tried, it can't find my E988 through USB.
I did install driver before I connected the phone.
Any other setting required?

As I told you, you need to be on download mode. Follow these steps:
1) Pull out the battery. Your phone will be turned off
2) Insert the battery but the phone shoud stay turned off. Plug usb cable to the phone but not to the pc
3) While the phone is off and battery is in, press both volume up and down buttons together (Do it with your single hand)
4) While you are pressing the buttons with your hand, plug the usb cable to the pc with your other hand.
5) You should see phone gets into download mode (DOWNLAD will be written on the screen)
6) Now the pc should recognize the phone.
7) Open LG Mobile Support Tool
8) You should be able to see that it recognizes the phone. If it doesn't, repeat the first 4 steps when LG mobile support tool is open.
9) After your phone is seen by the pc, choose Upgrade Recovery from Options.
10) It will check the FW from internet by using the imei Number of the phone or you can enter E988 and your serial number manually
11) Then it will download the FW and recover your phone. It will take time according your connection speed.

Thank you. Finally, Mobile Tool detected my E988 and is downloading the firmware now.
Something wrong with my Win7 , it just can't find the driver for E988.
Then I open XP mode in my Win7 and try again. The phone was detected and Mobile Tool open for action.
Thank you again. My E988 already bricked over a week.
Hello all,
Well, it's here... Unfortunately my phone got bricked last night
Can't boot into main screen and can't go to download mode anymore. The cause is, my phone was stuck when upgrading firmware and there's nothing to do about it except remove the battery, and then, BOOM!... "Secure Booting Error! Cause: boot certification verify"
Any LG G3 users here already experienced this problem?
I followed the solution on LG G2 sub-forum, but my ubuntu doesn't detect the port, although Windows recognized it.
If this happens to your G3 and you solved it, please share your experience
Thanks

Not at all.
Finally, I claimed my warranty with LG, and the motherboard got replaced.
It's all working now
You could have unbricked it... I've done that twice already
im stuck in this, how?
I'm stuck at the same thing since yesterday.
could you tell us the solution @nofait?
I've been researching about this and noticed one thing,
if I hold the lg combo (vol up + usb cable), and keep holding it until it passes the secure boot error and the screen becomes black,
my device (d855) goes to the Qualcomm Download Mode (it's detected as ''Qualcomm HS-USB QDLoader 9008'' on windows 8.1 x64)
Apparently, on that mode we could use Qualcomm tools (QPST) to reflash the bootloader and the matching laf image (the one that brings up the download mode)
so we could then flash any KDZ using LG Flash Tool.
To do so we need to extract the bootloader files, sbl1.bin, aboot.bin, rpm.bin, tz.bin, boot.bin, and laf.bin, from a tot/kdz firmware converting them to mbn format.
Then using QPST eMMC Download Tool, we load the partition table xml and 2 image files: the flash programmer file and the qcom boot image, which I'm still trying to figure out where to get them since I can't dump my own phone, and then we might be able to recover it.
I'm still looking into it and hopefully we can find a way.
I did not send my phone to lg service, yet, because I think they will take too long to fix it.
It happened to me a few days ago, but i had TWRP fully working so i could simply flash a ROM and then recover my things.
That thing about windows recognizing it as a msm8474 was a drivers issue (al least for me), i have a S5 too, i think that when i was tryng to get Heimdall working it changed the drivers (as you may know, s5 and g3 have the same board), so i just simply uninstalled it and then reinstall everything using .exe files from LG's website, after that windows 8.1 recognize it perfectly and i could flash KDZ without problems.
Other experience i had and that may help is what happened to me using an LGOG, couldn't boot, no recovery, no nothing, just trying to turn it on, it managed to get in fastboot mode (but with screen off and red LED all the time),from that point it was just about typing commands and flashing img to get it working

Hi,
You'll need to use a Windows 7 machine and the proper LG USB Driver (first post of this message) and change it to the COM41.
Do a BOARD DL and when the screen comes up and tells you to not touch it, ignore and press OK. Then press the power button and at the same type touch the "Normal +power". It should reboot and everything should be fine
Cheers!

So,
Should I use windows 7 32 bit or is it fine with 64 bit?
Will I need a .TOT file and a DLL for my model ( D855P 16gb ) or can I use a KDZ file?
EDIT: ok so I tried it, but flash tool failed to get model information from the phone.
were you in download mode? I can't get to download mode here.

I send my phone to warranty service, where they changed all the motherboard with new IMEI and SN.
Hope that they don't ask for money to repair the phone.

edit: solved somehow
I tried to flash latest 10L firmware, but I always get the messages Problem with communication between cell phone and PC. I did everything as instructed, selected Normal flash, but it won't work. I installed needed drivers, but when I reboot to Downloading mode, there is Exclamation sign in device manager. What could be the problem?
Did you change the port to com41?
Also are you using windows 8? If you are you need to disable signature verification.
I don't know how to change port to com41. I am using Windows 7.

It's in the guide that you said you followed. Open your device manager in windows and right click on the lg device that shows up. Next hut advanced and change the port to com41 and then click ok.
I did that, and it still shows the same message.

Bump.
Did you install the latest LG drivers for your phone? I don't know why this didn't occur to me earlier but that plays a big part in the PC seeing your phone.
Yes, I have driver. PC Suite works, everything works, but Flash tool doesn't.

You've got to boot into download mode and then use the LG FLash Tool 2014. There's one error stating there is an error with a connection, just ignore it and watch your phone screen! If it tells you stuff like the current version and the version it is about to install, just let it sit and wait till it reboots automatically.
The reason I am saying is because you say "Problem with communication between cell phone and PC" and it looks like the error that is supposed to show up.
Could you please re-do the process, maybe re-install the LG drivers and use LG FLash Tool again. If you encounter any error either make a screenshot or type the EXACT error message in here.
Good luck
I solved the problem.

For all who is experiencing the same thing problem is in 64bit OS but it is not a rule. People reported that they were succesfully flashed their devices on win7 x64. If you want to be sure use x86 windows and it should be working.
I'm in a bit of a pickle...
Phone is dead, I'm unable to wake it using any method, however PC sees the device being connected. I have tried to restore TWRP backup which was completed correctly but then phone stuck and failed to wake up again. I have tried to unbrick it using the LG flash tool and dll +tot files however this method fails each time -with factory model check error - and download fail notification. Right now im waiting for kdz file to download (im using the tool checking my imei to select correct one) but it takes ages with my internet.
Anyone has any ideas? Am i doomed?
Hi
Happened to me also. I got out of it by using LG flash tool and clicking on options and selecting restore recovery. It puts it back to stock and you then need to reroot etc.

Options? On mainstream there isn't any. Is it on the 2nd screen after adding the kdz?
Current progress
Phone:
No download mode
No boot on the phone
Device acts dead - only visible on my pc (serial port LGE)
PID and IMEI not available to read using LG flash tool 2014
Tried
Loading KDZ file - connection failed
using tot and dll with flash tool - Failed to connect to device
Read something about laf.img using adb... Anyone has any other ideas? Funny enough when I was searching forums I was not able to find more info about cases when device is not waking up at all. but now i see few very similar threads around? Possible flaw somewhere?

Thank God it is showing a serial port, try flashing with LG tools 2014, let me find a fix for your download error...
EDIT: Is your phone by any chance plugged into a usb 3.0 port? If yes then please plug it in a usb 2.0 port and try again...
I hope you are right. Screens hots should be updated same link:

It might be the PC (work pc at the moment and some IT limitations on it) however drivers installed ok, software confirms that I have latest software on my device - when phone is connected to the pc. After running Recovery Upgreade, it gets problem with comunication between the pc and mobile. in troubleshooting asks to power on the mobile (which I cannot do) before retrying. Also I have installed LG usb driver from outside as options coming with this software seem to be for really old models?
A thing I tried with another G3 was to connect the phone to the PC without the battery and then insert the battery, disconnect from phone and then remove battery again then insert and hold volume up and connect the USB to the phone again and it went into download mode and allowed the use of LG support tool as before.
Its worth a try!!

No dice... so far. I'm back home in 2 days when i can try all of this again making sure that PC is not restricted from any functionality... although it does sucks to not to have a phone until then. If you get any ideas I'm happy to try it as well.. as not like i have anything to lose at this point.
I decided to downgrade my LG G3 D851 from Lollipop 5.0.1 to the stock firmware.
I followed all of the steps of to downgrade my LG G3 D851 to the tee.
Towards to end, you have to restart your phone at the blue screen, this is what I did by taking out my battery when the big red "3" came up. It looked like it worked fine in the video right? But, to my luck, it just created a boot loop that I cannot get out of.
The reasons that I cannot get out of this boot loop are:
1. Because the LG G3 is so messed up, my computer will only recognize it as an unknown device even with the drivers installed.
2. The only way as far as I can see right now to fix it would be to follow the steps of the SAME video that caused this.
Any solutions guys?
Sorry if I am being vague, I'm kind of new around these parts and to rooting. If you need any answers I can surely provide.
Thanks!
Okay see if you can cancan get ti download mode. Take out your battery, put it back in, then hold volume up and plug in the USB. You should see a firmware update screen. Once there use lg flash tool to flash back to stock via kdz or tot.

Hey! The reason that the boot loop was created in the first was BECAUSE I tried to flash back to stock. Also, even if I did try to do this, the PC would not recognize the device and would register it as an "unknown device" even if I have LG G3 drivers.
Do you mind sending a screen shot of what you see in the computer? Does your phone still go to download mode anyway?

Do you have access to a computer with windows 7 or possibly 8. From what I know WIndows 10 is not supported by lg drivers yet. This could have resulted in your brick, however you can try to uninstall the drivers and re install them.
should try running the lg suite on your win 10 machine in compatibility mode for an older windows
