I am trying to install the original firmware and have not succeeded using
1.LGNPST (bin & dll: E971.E973.E975.F180_Original_TeenyBin-AA.bin file and LGNPST_LS970.dll)
or
2. LGs support tool (kdz: E97510D_00.kdz)
Problems with 1.:
No response when typing my IMEI and SN. Previously I used Teenybin and might have used the wrong .dll and .bin files - could that bethe reason?
Problem with 2.:

Other aspects:
1. If I only let my phone charge, I get a green screen, that indicates 3 ways to move on: Fastboot, Recovery and Download mode, if I press the specific buttons. But if I try to, it doesn´t work.
2. I have also been able to enter TWRP, but cant mount to find a rom to install. It only want to update the partition.
3. My phone is only able to connect to the laptop in Download mode.
I admit I´m a noob, but really think I have been trying to read and do stuff people have suggested.
I need to start a fresh, so if you have any suggestions to what to do, please help me - its already been 4 days now
Thanks!
LGNPST is NOT for E975.I managed to softbrick my phone with it .kdz downloader it's ok.
Do you have written the IMEI?
use KDZ downloader to get proper kdz directly for your phone. I'll attach bellow.
I suggest you charge the phone to full, download KDZ, then flash it with kdz updater in cs_emergency.
LGNPST works with E975. all files are available at team codefire

Now it worked - partly!
I had written the IMEI with the "-"... When I wrote it without, it started to download, the kdz file.
But as I run the KDZ Updater, I get this ERROR:

a "european" version doesnt exist

thx, I was confused by the dll file I use it´s named LGNPST_LS970.dll but I suppose that will work...?
and then I use Teenybins bin file, which should work for various models...
The real problem now is that I am able to get into Recovery mode but can´t flash any of the two roms I pushed to the phone?
the dll for lgnpst for the E975 can you find here:
http://downloads.codefi.re/shelnutt2/optimusg/e975
but ls970 should work too

thx, well, apparantly it doesn´t. I am able to install unti 85% and then I power off and the on and it reaches 100%.
And the I press the Finished (or something) button, but I can´t start it up again... I can only go into download mode (or sometimes TWRP).
I don´t see the LG logo at anytime but only the Google and the open lock?
Any other suggestions?
I know E975 came with JB, but you could try to flash the bootloader again. If this still doesn't work,you have 2 options my friend:
1. hardbrick it and send it to warranty.Tell them the phone just died
2.go to a service to jtag it. but this will void your warranty, since they must open the phone.

oooh, pls dont say that! I already send it to warranty, but I hadn´t hardbricked it so they said it was out of warrenty cause unauthorized software had been installed... will be difficult to send it back now hardbricked!
been on it for weeks, and even though I am just a noob, I have done so much even though I am not a nerd, used kdz downloader and updater and the LGNPST tool, making sure to get the right bin and dll files, LG TOols, , gotten familiar with command prompts, adb sideload irc etc.
but what is jtag???
I just want to feel the victory in finding a solution!!!
BIG SIGH...
JTAG is an interface which allows you to write/rewrite bootloader/software on a device.Unfortunatelly, it's quite expensive keep it home(about 300euros with accesories) so only services have them.Just look around your area and look for a service with JTAG. It will cost you 10-20 euros,but i guess it's better than no working phone .

Here is the proof G can be JTAGed.

thanks man...
difficiult to find here in Copenhagen, but will be going to London next week, hope to do it over there...
I only thought mine was softbricked?? I mean I can still go into download mode - isn´t that an indication of that??
True,if you can get into download mode you can restore it home. But, for some reasons, you are not able to do that.I'm sure if i would've got my hands on your phone i would fix it .
Maybe it's something you are not doing right, something not big, but it's messing up the procedure.

hello, if there is no juice, you can try to do as I did to my D855, I think it is the same, you will need to open your device and make a trick to go to downlaod mode.
IT is very esay that I put my LG G3 in download mode in 3minutes.
---------- Post added at 02:19 AM ---------- Previous post was at 02:08 AM ----------
just go with this guide , it is good.
http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
I did like it said and I got my phone repaired.
But, in step 8, I suggest you to not flash all stuff, because I think It is not necessary, I am pretty sure this was my cause to have the message : "Can't find matched cust for NT-code mcc/mnc"
I hard bricked my phone a second time, but instead of doing step 8 like he says. I just Made SDRAM test also and start. it will flash necessary stuff and reboot phone automatically.
To make a summary of what you need to do:
-- first put your windows in test mode if you have windows 64bits and install drivers
1-put your phone in download mode (screen off and without battery-sort of emergency download mode)
2-run boarddiag by willcracker and extract your Bin file in a folder.
3-choose port and choose folder
4-run the AP check and EMMC test
5-Run AP check, Emmc test and SDRAM test
6-phone will reboot
7-put him in download mode and flash you tot file
Done!

first, just skip steps 8 and 9 and replace it with:
it is a little bit mixed up but this is what he wanted to say:
6- choose port and folder where you extracted TOT file.
7- Check "AP" and "EMMC" and press start
here you finished with the link.
8+9- you need to Check "AP" and "EMMC" and SDRAM , click Start.
10-flash you phone with LGUP using Refurbish and choosing the tot file. (I prefer LG UP)
download here:
http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803 (do not install DLL file from this link)

3: Normally on lg tots the first string is : 4 xVLG-D8xx
4: And replace it as the model that is being detected on your phone
5: The next string you need to modify is: D8xx10c (in the case of the tmobile g3 the last 3 numbers are 10c this changes in every model)
6: Save it
7: Its done!
Flash instructions
1: You will need LGUP Store Framework, thanks to my lg phones.com for posting this tool
2:Connect Your lg phone in dwnload mode and set it on port COM 41
3: Open LGUP

Hello!
I tried to update my Vodafone Branded G4 with the europe not branded version H81520g_00_0720.kdz
The problem ist i just get "error code = 0x2000, invalid command response" from the LGUP software and everytime i start the phone it is in firmware update mode.
Any idea how to fix this?
Greetings
I got this too as I tried to install H81520o_00_0310.kdz then I thought that it is maybe related to the brand. So I download your kdz file and then it was working.
So I would guess try another number is the best what you can do. I believe it is because of selection of "upgrade". If you have a tot file for refurbish, then maybe another is working, but I didn't do this yet.
Probably the problem is the DLL.
Extract the DLL from the KDZ (the one you want to flash) and replace it with the one you have in LGUP (path; C:/Program files/LG Electronics/LGUP/Model/8992).

Hi,
I have LG H811 (T-Mobile) Variant. I receive error from LGUP everytime I try to flash this ROM=h81120x_00_1108.kdz
My LGUP shows COM =COM3 and Version=H81120v
The error is thrown at 9%
Nothing working for me I am very frustrated!!!
PLEASE SOMEBODY HELP ME!
Stuck with LG G4 (H81520i)
Same for me but with LG H81520i. I tried to flash these ROM* with their specific .dll that I extracted thanks to WindowsLGFirmwareExtract-1.2.5.0-Release. Always get "error code = 0x2000, invalid command response" from LGUP. The error is thrown at 16% on the computer, but at 7% on the phone. Now, I'm stuck in download mode. I also tried to change the COM port number, doesn't change anything.
*Europe General H81510B_00.kdz ; Europe OPEN H81510D.kdz ; H81510D_00.kdz ; H81520i_00_0922.kdz ; SEA H81510B.kdz
Only one ROM above matches the LG H81520i (the fourth one).
Informations about my (ex-)android firmware :
- Android version : 6.0 (Marshmallow)
- Kernel version : 3.10.84
- Software version : V20-SEA-XX
PS : H81520i is what is written on the LGUP software
______________________________________________________________________________
I found a solution (after several hours)
Uninstall all your LG softwares (except LG Bridge or others LG backup softwares) and go to 'C:\Program Files (x86)\LG Electronics\' to delete all folders and files.
Go to this link and click on "Download all". Extract the file and follow the instructions :
1) Install "LGMobileSupportTool.exe"
2) Install "LGMobileDriver_WHQL_Ver_4.2.0.exe"
3) Install "LGUP_Install_Ver_1_14_3.msi"
4) Install "LGUP_8994_DLL_Ver_0_0_3_23.msi"
5) Move "LGUP_8994.dll" in the repertory 'C:\Program Files (x86)\LG Electronics\LGUP\model\8994'
6) Open "LGMobile Support Tool" and click on "Install USB driver." to the left
7) Select "LGH815" (or your model) et follow the drivers installation steps
8) Do step 5) again
9) Shut off your LG and plug it to your computer while pressing volume up in order to enter download mode
10) Unplug your LG and the battery
11) Open "LGUP" and close it
12) Do step 9 again (download mode)
13) Open "LGUP", select "UPGRADE" and go select your .kdz file (the ones in the file that you downloaded or another one you have)
14) Click on "Start" and DON'T TOUCH !!!!!!
Big thanks to the people of this reddit post and of this XDA thread
See above

Uninstall ALL your softwares (except LG Bridge or others LG backup softwares) and go to 'C:\Program Files (x86)\LG Electronics\' to delete all folders and files.
Go to this link ( ht tps : / / ya di . sk /d / KIG5F8 2jmXcUR ) and click on "Download all". After downloading the file, extract it and follow the instructions :
1) Install "LGMobileSupportTool.exe"
2) Install "LGMobileDriver_WHQL_Ver_4.2.0.exe"
3) Install "LGUP_Install_Ver_1_14_3.msi"
4) Install "LGUP_8994_DLL_Ver_0_0_3_23.msi"
5) Move "LGUP_8994.dll" in the repertory 'C:\Program Files (x86)\LG Electronics\LGUP\model\8994'
6) Open "LGMobile Support Tool" and click on "Install USB driver." to the left
7) Select "LGH815" et follow the drivers installation steps
8) Do step 5) again
9) Shut off your LG and plug it to your computer while pressing volume up in order to enter download mode
10) Unplug your LG and the battery
11) Open "LGUP" and shut it
12) Do again step 8 (download mode)
13) Open "LGUP", select "UPGRADE" and go select your .kdz file (your one or the ones in the file that you downloaded)
14) Click on "Start" and DON'T TOUCH !!!!!!

Thanks Lucas for your time and help. It didn't work for me. I flashed another ROM named H811V20r_00_0111.kdz and it worked like a charm and it's tested on so many devices afterwards which worked fine without a single issue.
Here is the link to the ROM: https://lg-roms.com/official-firmware/LG G4-LGH811VK/H811V20r_00_0111/
Thanks for the help though.

You need H81520p.kdz to downgrade from Nougat!
You can download from here: https://www.4shared.com/file/hfyqh6iEfi/H81520p_00_0314.html
Can also see here if you need more files: https://forum.xda-developers.com/showpost.php?p=76571471&postcount=23

After install everything, replace the one in "C:\Program Files (x86)\LG Electronics\LGUP\model\8994" by the given one (or extract from the H81520p.kdz file).
See on the picture how your phone should be detected in "Device Manager":

You first start your phone with any sim or sd card?
Try to flash it again with the v20p and restart it without any card on it.
If it doesn't solve the problem, try a v10a. Maybe it works and you can upgrade starting from there.
Good luck!
