I realized there aren't any guides [in English] around here to help rooted folks that soft bricked their LG PRO to restore it back to factory settings. This should be useful if you got your phone stuck on the AT&T or the LG logo. Especially now that we don't have an unlocked bootloader or a recovery to reocver our soft brick.
Anyway, to start, a little disclaimer: I hold no responsibility if this method renders your phone completely useless, or burns and makes some nice fireworks. I'm simply writing this to document the process that worked for me. Use at your own discretion.
Dislcimaer 2: this method will wipe out your internal sdcard, apps data, everything! It'll restore the phone back to the way you got it from AT&T. Might even lose your cell unlock status (not verified). so keep these unlock codes handy just in case.
Note to linux users like myself: get your a** on windows or run it from a VM. VirtualBox with Win7 works fine.
Steps:
Download
1. LGFlashTools v1.5. Anything less won't work. Mirror: HERE
2. DLL file for LGE980
3. Drivers
4. The stock image file
Thanks to IOMonster for hosting these biga** files.
Install
1. Install the LG drivers downloaded above.
2. Install LGFlashTools v1.5 (but don't run it)
3. Extract the DLL and the TOT files from above and put them in a nice tidy directory
Drivers initialization
1. Put the phone into download mode. (Turn off device, keep pressing volume down while plugging in the micro usb cable. If this doesn't work, try holding both volume keys instead)
2. Let the phone initialize and install the drivers. Once done, in Device manager, you should see the LG phone listed under COM ports (something along these lines).
3. Find that LG entry in Device Manager, click on Properties, Advanced and then change the COM port to COM41 and close/save.
4. Unplug your phone! Important step.
LGFlashTools
To get this tool to work, you'll need to do a few tricks.
1. Set the computer's date to some time in July 2012 or before.
2. Disconnect the internet
3. Find a serial number or register key from somewhere on the web (a google search for lgflashtools serial will yield some results). Can't help you here and please don't share any keys in this thread or get us in trouble.
4. Execute the LGFlashTools. It should ask you for a key, put it in. Now you should see a dialog where you can load the DLL file and the TOT files that you extracted earlier. Put them both in here. Click ok
Flashing
5. There is a yellow arrow on the top left. Click on it to initialize the process. Once done, it should say "ready/finished" or whatever.
6. Put the phone in download mode again, and plug it into the USB port. LG FLash Tools should start flashing it automatically. When it's done, it'll automatically reboot into your stock AT&T rom and all of your data and internal sdcard files are gone.
Profit

Thanks .... great info!!!!!
Nice. Hopefully they sticky this.
Welp, just bricked the phone again but was able to flash the tot... very simple and quick lol ur the man mac
this worked perfectly fine for me. i 1st tried it on w8 but after plugging in the e980 and letting the drivers and such install, it did not show up under com in the device manager. in fact, there was no com section. it did show up under devices and printers and i tried and could not find a com setting there. i went ahead and tried to flash but since i could not change to the proper port, the flash tool never found my e980.
so instead i just did it all on a w7 box, the device was listed under com, and i went along with the flashing.
thank you.
Think this will fix the bricks that are happening when they try to mess around with the bootloader?

Nope. Mess with the bootloader and you'll risk losing download mode.

My friend just bricked his and the wi9ed the system. I can get ir into download mode for him but thats it. I tried recovery mode but trying to do that or boot regularly it just shows lg the an android with the spinning symbol on it the lg again then lg 2 more times and just stays there. Can this be fixed with only download mode? Again I plugged it in and im not sure its being seen by the computer.
Make sure you have the drivers installed and use pc suite to get back the firmware

it doesn't hurt to try. I'll bet it will because I was left with something similar and this method got me back on stock.

Pc suite? Do you mean lg flash tools? I downloaded it but it wants me to log in to use it. I havent found a log in for it yet.
Download lg pc suite it have lg flash tool in it
Then you search a little in menus for firmware urgence recovery something like that and if it don't work try update in the same menu
And if all of that didn't work I'll find you a link to flash a kdz

I seem to have an issue with my E980, i cant get data my apn directory is empty and cant seem to add an apn it will just not save! anyone else have this issue or know what i can do? thanks!
Reboots to recovery only
Ok, I flashed the recovery in this post using the dd method http://forum.xda-developers.com/showpost.php?p=43460298&postcount=208
The value pack was trying to download on my phone and instead of cancel, I pressed install. Now the phone only boots into that recovery. I have everything from the op downloaded, but instead of download mode it only boots into the recovery, any ideas?
When it boots up, It says the following for a couple of seconds:
Code:
Secure booting error
Cause: Device Unlock, so boot success!!
Edit: Got it into download mode by holding down both volume keys and plugging into usb. Thanks!!

I'm glad you got it resolved! I just edited the OP with this information.
I have the ATT model of LG Optimus G Pro E980.
Today, I rooted my phone and everything went smoothly as it usually does. Everything seemed fine until i tried flashing this http://forum.xda-developers.com/showthread.php?t=2428207
Now I can only boot and get a LG screen and then it just turns black. I got into download mode maybe once or twice but I can't repeat it and the device doesn't seem to show up on my computer either way. I booted into CWM maybe once by smashing keys and it just randomly popped up but its also not repeatable . Any suggestions, I'll honestly try everything.
Thanks

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.

The Support Tool does recognize the phone, but I am unable to upgrade recovery. It goes all the way to downloading software, but the time elapsed stays at 00:00:13 (13 seconds). I do have the firmware installed on my computer though, and I am now able to access CWM. Help?

Stupid question, but are you sure you are doing it right? To enter download mode, first turn the phone off. Then hold both volume buttons, and plug in the USB cable to your computer. Do NOT press the power button. Is this what you are doing?
Also, are you saying you rooted an F180 KitKat with Framaroot?!?! I find that very hard to believe, as it failed for me, and other people also confirmed that it didn't work...

The same thing happened to me .. The phone didn't show DOWNLOAD MODE. ... i still flashed the stock kdz by these steps
1.. switch off ur phone
2.. keep the up and down volume buttons pressed and insert the usb cable
3.. open Kdz updater ..
4 .. click read phone information. .and wait for a minute
5.. if it even shows a slight progress seen in the green bar , then you have a go..
Notes
:1.. if the kdz updater even hangs and stops responding while reading ur phone info.. and takes some time.. ur phone is connected in download mode even it shows the slightest progress in the progress bar ( green coloured)
2... if u cant switch off ur phone due to frequent restarts. . just keep the cable connected and the volume buttons pressed while it is restarting
[you can also see ur computer's device mgr for ur phone connection ]
then just flash the Kdz as you do..
I HAVE DONE IT MYSELF several times when my phone didn't show Download mode on the screen.. but cannot guarantee it'll work for you too.. I I'd recommend you to give it a try as it always worked fir me..
BEST IF LUCK

follow these steps.. :if you have less than 1 gb kdz file
1) Download the latest KDZ from LG's server for your phone via
the app below (kudos to the creator)
http://www.mediafire.com/?cgeb6o5osy2yl9c
2) Make sure you have LG United Drivers already installed,
otherwise download from below
http://www.mediafire.com/?82nt1aeh04aqa3m
3) Download LG KDZ Updater
http://www.mediafire.com/?sj5y073xal03ntw
4) Download the manual adb wipe batch file
http://www.mediafire.com/?ru7erfxsz7p7s3p
5) Put your Optimus G into Download Mode by switching it off,
attaching the usb cable to the phone, holding both the up and
down volume buttons at the same time and lastly inserting the
usb cable into the computer; wait for the drivers to finish
loading if doing it for the first time.
6) Unzip the downloaded updater zip file and run KDZ_FW_
UPD.exe. Use the settings below
Type: 3GQCT
Phone Mode: CS_Emergency
KDZ file: navigate to the folder which you have saved the
downloaded KDZ from the step (1)
Click Launch Software Update and wait for the flash process to
finish
7) Your phone will restart itself when IParam = 90 is displayed
and proceed slower until you see IParam=1 again (which
signals the end of flash, you can safely exit the program then
and remove the cable from the phone). If phone boots up
normally, congrats, skip the steps below and proceed to use the
phone as per normal.
However, this most probably will not be the case for newer
Optimus-es, as the data partition somehow wasn't wiped even
when KDZ-ed, remaining 'dirty', thus causing bootloop or
security infringement.
8) If the phone is stuck at the booting up LG/Telco logo, you
will need to manually wipe the data partition.
9) Force the phone off by holding the power button for appx
15secs.
10) Put the phone into recovery mode by holding the volume up
and home button concurrently, then press the power button. Let
go of all the buttons after you see the LG logo on screen for the
2nd time and the screen goes blank thereafter (backlight may
still be on). The phone will kind of reboot and then enters
recovery mode. Repeat the process if you did not get it the first
time.
11) With the phone in Recovery Mode, connect it to the
computer, wait for the drivers to load (if doing it for the first
time), unzip the wipe batch file downloaded earlier from step (4)
, double click on wipe.bat to execute the wipe command.
12) Your phone will auto reboot when wiped and (hopefully)
boot as per normal.
Hope with this simple guide fellow members will feel safer when
rooting or removing non essential LG wares from their Optimus

Your boot loader is broken. Gonna have to get to the down load mode and reinstall either the or the stock. You can probably flash the recovery with .IMG file with lg flashing tool. Nerdy blond's twrp is one of those files that you can use. You can even try installing it first with the adb shell command, you can get the instructions at the same place where you download.

Also, I cannot use adb commands to force the phone enters into download mode as it shows nothings under "List of devices".
Is there any methods I can go into the download mode???

If your phone shows LG start screen, it should go into Download mode. I had similar problem few days ago while I was testing some kernel patches, it just froze on the LG screen. Solution was to unplug it, remove it's battery, SIM & SD (you don't have to remove SIM & SD, I just work that way) , make sure it's off, return battery back, press Vol + & Vol - at the same time and plug-in the USB cable.
Before that, make sure you have installed LG Unified driver (can be obtained via LG's software from support site), because without that Windows won't recognise your device.
After that, once you make your phone usable with Freegee/whatever you use to install initial recovery, flash official TWRP, because others are too old - that Philz CWM is old but still working with Lollipop but not work good and is tends to lock itself into a bootloop if you use hardware keys to enter; that other one, from GPRO_recovery APK is not supported and not working well (for me since day one), so it should be replaced as soon as possible.
Also, I can suggest you to flash your phone from stock 4.1 (not KitKat), root, flash recovery via freegee and after reboot update to latest official TWRP via Flashify.

The screen is still stuck on LG logo and I cannot find the device in hardware manager (cannot recognize it).
I cannot do anythings until it can recognize it.

Which version of Windows are you using? It should be displayed under Serial ports in Device manager (named something like LGE Serial device) and LGFlashTool should recognise it immediately. I can't make you a screenshot/check for real name because I'm running Linux right now and can't reboot.
Also, try with another cable/port, remove all other android drivers you may have (Samsung's, Google's...) and disable antivirus.

OK, it doesn't enter download mode. So, step by step:
- remove battery and leave it for 15-30 seconds, return battery
- press Vol+ and Vol- at the same time and keep them pressed,
- plug USB cable in while keys are pressed
It should immediately put you into download mode, with no LG screen, just black screen with gray box and red text I've described to you.

I understand what download mode screen is.
I followed your methods, bur I still cannot enter it and the computer cannot recognize that.
Sorry for disturbing :crying:

So, whatever you try to do, phone just shows LG logo, not even a message in an upper left corner?
I'm running out of ideas. I have exact same variant (E988) but only time it didn't want to enter download mode this way was when cable I was using was broken...

Hi guys,
Some people including me faced Hard brick issue with LG G4, which has now two solutions. the first is temporary, i discovered it and it involves using an SD card flashed with Original EMMC dump ( i tested it with H815 ands H811) , the second needs advanced hardware, equipment and soldering skills ( JTAG) .
The solution that i want to explore is trying to revive the phone with the SD card.

http://forum.xda-developers.com/g4/development/unbrick-lg-g4-h815-9008-qualcomm-t3452853
The H811 dump that i made has TWRP recovery and unlocked bootlloader, so if someone know how to help that would be awesome.
How ???, its very simple. I dont have very good UNIX architecture skills , but if the SoC successfully booted from the SD card. We could see if it detects the EMMC memory ( with parted or with LS command). I personally Tried to brow /dev/block directory from TWRP i hoped to find MMCBLK1 or something but that was unsuccessful , im pretty sure the TWRP or the Soc Does not mount it automatically .
I really dont know How , but i'm very Sure that there is a Solution headed that way , So if some one is Good with Unix architecture and can find a way to soft Flash the EMMC from TWRP ( installed in the SD card ) it would be very Nice
hi,i tried the sd card method...it boots but immediately gives me secure boot error (1006).
i have an h815 bl locked

You can fix fastboot mode with this way.
1. First you need to download stock rom that your phone supported. extract laf.img file from rom and copy it into fastboot directory
2. download LG Flash Tool and make it ready
3. open flash tool and load firmware and dll that support your model.
open command prompt and make sure you in fastboot directory where the fastboot and related files are stored.
Run following commands.
fastboot erase recovery
fastboot erase laf
fastboot flash laf laf.img
fastboot reboot

Hurry up, now you need to start flash with lg flash tool, if device does not start into download mode. remove battery and insert again, press and hold Vol Up btn and plug USB cable it will boot into download mode. and your device com port should be 41, if not change it in device manager. and start LG Flash tool to load stock rom. once it finish loading rom your device will start and will show you factory test 1, 2, or 3. if it stuck there more than 3-5 minutes. reboot your phone. now you will have welcome screen.
I hope this will work with supported models.

lol, when you see a screen with 0% and a usb connected image, that mean your battery dead
why not just try to charge your phone? or replace a battery?

Hello, well after what happened I thought the same and went to buy another battery and when they tried it did not work, I repeat, not fastboot, no logo, no recovery, only a small vibration without screen, it is not detected by the PC in any of its modes as dead, the detail is that this happened after restarting when I had flashed bootloader N, rom V30, magiistic, I gave it restart and it did not turn on again, so I discard that it is hardware .
I think the problem was that I flashed the bootloader with full aboot, that gave me hardbrick I was told in a forum in Spanish I leave the link I hope you help me thanks

Hey MichaelCV
I have exactly the same problem with my LG G4 H815p. I was running [ROM][H815] H-ROM G4 NOUGAT [v29a] _ LG G4. The phone was up and running and last night I flashed the "LG-H815_29a_Modem_and_Bootloader.zip" to try resolve an issue I was having with the mobile data indicator not showing. I flashed the zip in TWRP, rebooted the phone and now it is bricked. I have exactly the same symptoms as you. Windows and FWUL does not see the phone, no matter what combination of keypressed etc that I try.
Lets hope we find a solution here for it.
Chris
