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

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!!

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

hey budy i'm a noob i don't understand what should be needed to delete and replace with what and where is this script make it clearer if that is possible (i don't want to brick my G just want to go back to stock)

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-h811-9008-qualcomm-t3456417
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
Hello

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.

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.

If I remember correctly (please check threads here, it's been a long time since I've used this device, so memories are fading), download mode is activated when you press Volume Up (or both of volume buttons) and insert USB cable. I know that E98x has some strange button sequences, like rebooting to recovery is a two step operation (Volume Up + Power until navbar blinks, then power button twice, that's the only way mine wanted to boot into recovery), so please check around.
As far as USB connection issues, don't use USB3+ ports and if you're on Windows 8.1+ and later, run with Administrator privileges. I never experienced that one (used LGFlashTools from inside VirtualBox running Win XP for all my needs, I'm not a Windows user), so can't really help much but forums are full with explanations how.

Thank you very much...now the phone is back to initial state. This what i've done:
1. Download LG Flash tool from http://lgflashtool.com/
2. Download LG USB Drivers from http://lgflashtool.com/
3. Install LG flash tool and LG USB Drivers
4. Plug usb cable to phone
5. Hold volume buttons and then plug the usb cable to PC (i use win 10)
6. Voila, the Download Mode icon is showed up
7. Run LG Flash Tool (Administrator privilege) & follow the instruction (i use e988 v20c stock firmware)
8. Phone back to normal (only if you use the correct stock firmware)
A very big thanks to ShadySquirrel
Hopefully this thread can also be used as reference for anyone who has the same issue as i had
Hey everyone!
So, I've got a HD1903, 8GB RAM 128GB ROM. I updated to OxygenOS 11.0.02, but it was still buggy as hell, so I decided to downgrade. I also had rooted the phone, and decided to get rid of that too. I went to the stock fastboot roms page, downloaded the 10.0.13 ROM and used 'flash-all.bat' file to clear everything. But halfway, it reboots, goes into recovery, then goes to Qualcomm Crashdump mode. That's it. No code or anything, just Qualcomm Crashdump mode, in Blue and Red letters. I tried to hold vol-up, vol-down and power to get into fastboot, but it just loads the fastboot splash screen, then goes back to the same qualcomm crashdump mode screen. Even if i try to hard reset it, by holding vol-up and power, it still goes to the same screen.
Anyone know what to do? I have no idea how to use the 'MSM tool' that everyone talks about, so any guiding advice would be great!
Thanks!
DM me here - https://www.facebook.com/prantor.khan.16 I'll help

I didn't install TWRP, this was all on stock recovery. I also cannot get into fastboot mode.
Msmtool does not need twrp or fastboot--just the software, rom image, drivers, and button combo pushes and holding
OK, so I got it working again, thanks to the advice of reddit users, discord users and the latest msm tool and some googling. I held the vol-up and vol-down buttons for 30 seconds, then connected it to the laptop, with msm running, to a usb 2.0 port, and pressed start. hey presto, it worked. Thanks guys!!

Hello
Using the MSM tool is very simple, you just have to download it from this link.
https://drive.google.com/file/d/12y3lO0wIgb2_LSDeVw9x_2C_HjbgZlb_/view?usp=sharing
NOTE: only works on Windows PC
1. Unzip the contents of the RAR into a folder.
2. Run the MSM application
3. Click Start.
4. Connect the cell phone in EDL mode (volume up + down button)
5. Wait for the process to finish (it takes a long time, please be patient)
6. The phone will restart automatically and a message will appear informing you that the equipment is damaged (don't be careful).
Note: The phone should automatically boot into fastboot mode and display a menu, but if it doesn't and instead boots to the T-mobile screen, you need to force shutdown with the power button for several seconds and then manually start it in fastboot mode. (volume up + volume down + power button)
7. Now you need to unlock the bootloader with the command from a Windows CMD window, but you need to download this ADB tool first.
https://dl.google.com/android/repository/platform-tools-latest-windows.zip
-Unzip the tool into a folder
-Open a Windows command window, in administrator mode and direct it to the path where you unzipped the ADB tool.
8- Execute this command while the cell phone is connected in Fastboot mode.

9- A question will appear on the phone in which you must allow the unlocking.
-With the volume keys select the option to allow it and press the power button.
-At this time your bootloader will be unlocked.
10. Copy the ADB tool files into the folder where ROM 10.0.13 is and replace everything.
11. With the phone connected to the PC, on the command line, run the flash-all.bat file
12. When the phone restarts and the yellow and white letters appear informing that the phone is not safe because the bootloader is unlocked, repeatedly press the (volume down) button until a menu in Chinese appears.
-PC will detect the phone again in fastboot mode and continue to flash
-Leave the phone and PC still until the process is finished.
-In the command line it will indicate that it cannot find files or partitions (ignore it)
13. Finally, the computer will restart automatically and you will be able to use it normally.
Notes:
1. If the phone after the flashing process with MSM starts up and shows the T-mobile logo, don't worry, just turn it off with the power button and connect it in fastboot mode.
2. Do not try to use it with the firmware that I install with MSM, as it will not work properly.
3. Before locking the bootloader again (if you plan to do so) first update via OTA, to the most recent version of Oxygen, otherwise the system will crash again and you will have to repeat the whole process.

Oh wow that was a long and well defined post. Thank you for taking the time to type it out.
As it happens, I fixed my issue already (IDK if there's a solved flair for XDA or something?). I downloaded the latest (10.0.15) MSM Tool from the XDA page, held the vol-up and vol-down for 30 seconds this time (as per advice from discord users) got the phone into edl mode, connected to a usb 2.0 port and let msm tool do it's thing. Everything is working perfectly now.
I've got the same problem but even with holding vol up+down buttons for 30 seconds I can't get into edl mode. It boots into qualcomm crashdump mode. I don't have fastboot working, I only see fastboot splash screen for a sec and then qualcomm crashdump mode appears. Could someone help?! As soon as usb cable is connected phone boots into qualcomm crashdump mode. no matter what I do.
Also do service centers undertake servicing for such phones which bricked because of badly flashed roms.

If they're going to just change the motherboard, I wonder what the EDL mode is meant for. Anyways, I won't go for motherboard change one can buy a new and better phone at that kinda price.
Anyways, I Fixed it through EDL method, you have to hold vol up and down simultaneously and immediately connect to windows (while still holding both buttons) via original USB cable. Check with Device manager if your device shows up, it's easy enough but you might have to keep trying to you get it right. Thereafter, disable driver verification in windows and if Sahara communications failed message appears in msm tool, turn off phone and repeat the procedure again.
The repair peeps only fix hardware and not software. It's more cost effective for them to swap out hardware faster than messing with msmtool like us

OK, so you won't get any confirmation that you're in EDL modem you just have to wing it. What I did, I first opened the MSM tool on my laptop, connected the USB side to the laptop at a USB 2.0 port, and kept the USB-C side within easy reach. I held the buttons down with one thumb for 30-35 seconds, and while still holding them down with one hand, i connected the cable to the phone and clicked enum in MSM, it showed connected so I let the buttons go, and it didn't restart. I clicked start, and it worked for me.

You don't have to hold buttons for that long, you can immediately connect it to PC. There is usually a sound to indicate that a new device has been connected to windows, you can also keep device manager open for confirmation. This video really helped.
After receiving a " qualcomm crash dump" , I was able to boot into recovery. Then I had done a factory reset.
Phone turns on fine, charges as well.
Although, On my Laptop / Desktop it does not see the phone within MSM, ASs well as ADB, Fastbootd or device manager.
I have the correct drivers downloaded.
Ideas ?

I went ahead and ran another factory reset via recovery, no luck.
New cable, another PC?

Tried both, my desktop would always connect, adb, fastboot, etc.
I had just just freshly installed oneplus drivers including qualcomm on my laptop. Device was not recognized before driver installation or after.
Figure id try on my Mac, and linux laptop. no dice.
ADB is enabled.
Here are the drivers that are installed on my PC ( I enabled hidden devices, in order to see them ) These were recognizing prior to " qualcomm crash dump" . Not phone will not even be seen
