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:

[Help] LG G4 H815 LGUP failure

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

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

Okay I'll try this but please tell me that
I have to copy lgup_8994.dll from H81520p or use original dll which is installed with the LGUP 8994 installer???

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).

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!

now again I tried H815v29A so it installed after the installation of old original version , now please tell the method of rooting Nougat on H815v29A urgently XDA experts???
also Twrp not installing on H815v29A which was working on marshmallow/////
experts reply???

[SOLVED] LG G4 stuck on Firmware Update screen

Hi all. I'm writing because I didn't find anything useful to me.
My LG is stuck on Firmware Update screen:
https://drive.google.com/file/d/0B2dMoe8S9yx4VGNkR1VtMjVRdkU/view?usp=sharing
(below there are "633A B88 // Modified).
All began when I wanted to re-lock the bootloader. So, I read somewhere that I could do it with fastboot oem lock. I did it and the result was that the bootloader was re-locked. So I rebooted my phone and it stuck at
https://drive.google.com/file/d/0B2dMoe8S9yx4dDR5cDFQT0RIZ2c/view?usp=sharing
and there wasn't "may not work properly" but "it will not boot". So, I entered to download mode and I tried to flash with LGUP V20G kdz (I was on 29A but it's zipped). When it arrived at about 24% it stopped with error 0x2000 (but phone was identified). After this I rebooted my LG and I can access only to download mode. When I turn on the phone there isn't anymore "Your device is corrupt, etc.", directly to download mode. I tried to enter to download mode and recovery mode (but stock can only reset), so if someone knows others hardware button combinations to get other modes, please tell me.
I hope someone can help me, obviously not service.
Thank you in advance.
P. S. Sorry for my bad English

No one?
For me it's enough only a way to force installing firmware on LGUP.

I fixed in this way:
- go to https://forum.xda-developers.com/showpost.php?p=73493577&postcount=78 and download attached file. It contains two DLL that you'll put in C:\Program Files (x86)\LG Electronics\LGUP\model\8994 (deleting other DLL file). Don't worry if they are two DLLs and not one. Then, when you open LGUP you must flash (UPGRADE mode) H81520p firmware (that you can download here: http://storagecow.eu/index.php?dir=Xda/LG+G4/H815/). Then wait and your phone should revive, like mine. I hope it'll work for you as worked for me.
Obvioulsy you must have H815 version (not variant) to do this.
EDIT:
This dll works also for H818P

Same procedure but not same file: in the solution I linked and I used there are two DLLs (and I can see the difference on LGUP, that says "DLL version 0.4.0.0"); instead, in your solution (that I tried before using the one I linked), there's only a DLL and, if I'm not wrong, its version is 0.3.3.23 or something similar. Anyway, it's not a problem, I said it without any aim.

woohoo

Unfortunately didn't work for me. Thank you anyway.
I fixed in this way:
- go to https://forum.xda-developers.com/showpost.php?p=73493577&postcount=78 and download attached file. It contains two DLL that you'll put in C:\Program Files (x86)\LG Electronics\LGUP\model\8994 (deleting other DLL file). Don't worry if they are two DLLs and not one. Then, when you open LGUP you must flash (UPGRADE mode) H81520p firmware (that you can download here: http://storagecow.eu/index.php?dir=Xda/LG+G4/H815/). Then wait and your phone should revive, like mine. I hope it'll work for you as worked for me.
Obvioulsy you must have H815 version (not variant) to do this.
EDIT:
This dll works also for H818P

No problem hope it works out well for you. I had trouble understanding the software but I managed to unbrick my phone with it.

I've a look to the zip file...
The exe file looks "bizarre"
┼¼▒╚ÐÃ╝▒¥╚╣ñ¥▀V1.1.4.exe
The MD5 file is corrupt : "erreur d'entête" in French
I think it is because of the file name. I'll test unzip under linux

Yes mines like that too for me the program name is:Ŭ±ÈÑǼ±¾È¹¤¾ß. Haha.
I literally had to guess what I had to do to get it working the pictures helped a little.

I change the name using Linux Mint.
I'll upload the file in a few days.
I'll have a look the the text files (resources) in order to give some explanations if I can do it.

There's no need to rename the files/folders using linux. Opening the .zip file in explorer (win10) is enough to uncompress it, then tou can rename files/folders as you like.
The software installs and run just fine. Nubia Z17 is supported up to rel. 3.08 (so it seems exploring the "Recovery" folder under C:\Program Files (x86)\nubia\BackupRecoveryTool.
All the recovery files are in .7z format and password encrypted (don't know at the moment if the password is embedded into the recovery tool main program.

Don't have W10
<HS>
I've some problems too to unlock the boot loader.
After unlock it once and flash TWRP, all other attempts are KO (can't flash with adb).
I wanted to flash the "standard recovery" to install the OTA update (modded 3.08) and reflash after TWRP.
I'll test it later

Yes, I did!
I've downloaded this file, extracted the DLL with the KDZ Extractor, moved the DLL to the C:\Program files\LG Electronics\LGUP\model\8994 and then it freezes in 25%.

I've tried in a Windows 7 PC and it worked (???????????)
So, yeah.

What displays LG up at 25%.
For example at 11% there ist GPT compatibility.
Did you replaced the 8994.DLL vor are there two now?
