I understand. I'm just asking if you really using right boarddiag (thread that I mentioned - willcracker.rar)
Also be sure that you have a phone connected to right port (check it in device manager)

yes im using the r8 port it shows in device manager and in board daig also i gave port 14
before my phone was going to get bricked its battery was low
is it affecting the procedure i think my battery is not charging
when i remove battery and connect to pc phone shows battery not inserted sign when i insert the batery it disappear and no sign of charging
i thought this might help:good:

You have to use the original LG usb cable. Dont try with fake china cables because its a lot possible to have troubles with them.

[Q] P350 fastboot bricked

So I used ROMmanager to get clockwork recovery mode. Now when my phone entered the recovery mode it just say:
"Fastboot mode started"
"udc_start()"
If i connect my USB cable to it it says --suspend--
Now i tried using KDZ_FW_UPD in Emergency mode to restore original firmware but it cant find the phone. The log is:
[R&D Test Tools Log File]
10:50:59 : Launching SW update
10:50:59 : Unpacking KDZ
10:51:14 : KDZ file extraced
10:51:17 : Files were extracted.
10:51:17 : LGMobileDL Load.
10:51:17 : Port = -1
10:51:17 : Connecting to phone
10:51:17 : PHONE WAS NOT FOUND!
10:51:19 : ===FINISHED=== ​
I tried this procedure on 2 pcs but no luck. It seems that my phone can't connect to PC with usb cable.
I installed LG Moblie United drivers and disabled the lg modem thing in device manager. I am using Windows xp Proffesional SP3.
So does anyone has any clue what I am doing wrong ? If u need more info just ask.
Maybe if I try from some linux distro it will detect my phone ? But what tools to use then ?
Use fastboot to recover the phone. Check the wiki at the Troubleshooting section.
---------- Post added at 03:31 PM ---------- Previous post was at 03:12 PM ----------
I recommend using drivers latest version. Last time I checked, United Mobile Driver was version 3.7.2 release 4.9.8.1 and Modem Link Driver was 1.0. I'm providing links for download from my personal Dropbox folder because I don't remember from which LG site I downloaded them from.

i had the same problem few days back... (ROM Manager sucks).... ok.. so.. before connecting the phone to the PC.. remove the battery, press both the volume keys (no need to press the power button)... and connect the usb.. now the cell phone will be in emergency mode.. try launching the software with kdz updater now... it should detect it.. after its detected.. connect back the battery (without disconnecting the USb cord ofcourse)... hope this works.. good luck
Good tip, adding to wiki later...

Didn't I said i did that ? My PC wont recognize my phone in fastboot or emergency mode, with fastboot being stuck at udc_start() and when i connect USB it says "-- suspend --" ,
I tried this guide madmanzrocks still dont see phone.
deleted lg modem, reinstalled all usb hubs, tried 10 versions of LGunited drivers, used both official update tool and kdz nothing works(can't detect phone), and also tried from cmd.
My problem isn't how to unbrick but rather why my pc won't recognize my phone :/
So, no feedback (USB Device connected sound) when conneting the phone? I assume you have tried all ports available.... Long shot, but maybe the phone's USB connector is dead... You have some background on electronics? If so, you can follow the service manual I reposted recently at the General section to check if the connector is gone (p. 113).

yeah tried all ports, I¨ll try on several other pc's. no connection sound, but phone is charging. I have quite some background on electronics so ill check it out when i try this on couple others pc's. Don't want to dissaemble it quite yet and if it rly is dead repair will probably take more money then i spent to buy it(I got it 2nd hand for around 50 $). It happened before that my PC coudn't recognize some devices but never like this. I ussualy get device not recognized, malfuctioned or smthing like that .

as I mentioned the same problem was solved bu connecting the cell phone with the battery removed. But if even that doesnt works for you, then maybe there is a fault in your PC. Does your PC instantly recognizes USB Pendrives? And which OS are you using?

Hey, i have the same problem, and i also can' t fix it, i tried all ways, but my pc dont detect my phone... so i hope that someone will find a way how to fix it... but it' s not normal what is happening with this phone...
Don't know if it helps or you already tried it.
Start fastboot v2 and start the flash so it waiting for device.
Then plug in usb and start phone in fastboot.
That worked for me before.

I can try.
First start fastboot v2 on your computer.
Load the recoveryimage amonra or cwm5 (not cwm6)
Start flash so it say searching for device.(or something like that)
Plug in usb in computer.
Start your phone in fastboot.
Plug in usb in phone.
If that don't work you can try to instead of start phone first start it with usb cable.
Can need to unplug usb and plug it in a few times if the device say suspend.
Hope it helps.

Can you please add the links to this files or the files? I would be very thanksful...
Up to this point i tried all the methods you guys told me and some i found myself. Nothing worked for me as my PC stil won't recognize my phone, I have also tried all this methods on 4 PCs(2 had windows XP Proffesional SP3 with all the updates, and 2 had Windows 7 SP1 with all the current updates installed(note that 1 version was 32-bit and other was 64-bit).
My conclusion is that the USB connector is DEAD, even thought i can still charge my phone trough it. I probably won't be trying to fix this anymore as I've found an 4th gen iPod and i'll be using that from now on.It is true that i can't make calls(at least not the standard way, you know, it doesn't support SIM cards), but i have my old dumbphone phone for that and this will be used for just about anything else.
So thanks to all of you guys that tried to help me but i fear this is unrepairable. If anyone want's this phone I'll give it to you for free so you can have some fun cracking your head to see what is wrong . I only ask that if you find a way to fix it you post it here and notify me about it(send me pm).Otherwise do whatever you with it.
I have solution

D851 Hard Brick

I cannot boot into download mode and cannot boot into twrp. The phone will not boot no matter how long i hold the power button and there is no lights. When connected to the pc it shows up as Qcom Dload. Can someone please create a debrick.img. All you need to do is flash this in twrp and send me the debrick file which should end up on your sdcard.

This has been tried before and it didnt work for the guy. Have you tried flashing a tot? It has the begining of the emmc so same outcome but you can skip all the sd card work. Good luck if the tot fails and no one steps up ill get you that debrick file just to see if your luck is better.

That was a no go i tried the older dll that bypass model checks but still fails. Guess there is a linux method that worked on the older g2 and someone with a g3 reported success so i already extracted the TOT files i need to dd over from linux.

Yeah that's probably your best option I have a partitions dump from the tot if yours are not working for some reason. Instead of installing twrp If I was you I would boot into download mode after and flash the tot. I did do a debrick dump with the script that I can get to you tomorrow some time and if that doesn't work tell me and I can give you a link that has 250-500mb range for the dumps from when I was helping the other guy. They weren't made with a script but with terminal emulator but they should be the same thing just bigger because the smaller dumps weren't working for him. Any way here are the partitions just in case https://www.androidfilehost.com/?fid=23622183712472493

Oh and before I go to bed another thing you can try if you can send the images over but they don't seem to work. Hunt down the fastboot laf.img send that over then do the rest of the partitions via fastboot instead. Good luck!
Dead phone
Dead in the water. Only qpst seems to see it besides device manager (Qualcomm HS-USB QDLoader 9008). The linux method was for people who get the lg logo. I don't get anything but a black screen. Problem is i don't know enough about the qpst software to guide you on making the files. All i can say is try to make a backup using qpst and provide links. Don't know what else to do.

In order to get you the files someone needs to reboot from the hidden menu into somthing I cant remember. Its not mini os and the d851 lacks the option in hidden menu atleast I didnt see it. The d855 hidden menu has the option and I was going to try it but he ended up sending it in before I got around to flashing the d855 rom. If you want to fix it yourself and can do without a cell phone for a few days I can try but might not be able to get you the files until sunday if it works.

QPST
So it looks like i will need a hex file and mbn partition files vs the bin files that come from the tot file. From what i read in the forums lg offers a 1 year warrenty. So i guess as a last resort i could send it in for service but i would rather try to resolve it myself.

Qualcomm MSM8975AC
Hello
I tell them my story, mistakenly doing a ported rom stock LG G3 Marshmallow, I flashed my phone with the stock rom from Marshmallow (model D855) and after that I have bricked the phone. No download mode, no emergency mode, only is recognize for the computer as AndroiNet usb port serial.
Could please you help me to unbrick my lg g3 Phone model d851,t-mobile variant. When I plug in my Phone to computer, this is recognized as lgandroinet port serial but I have made a testpoint (open the mobile) to change the phone mode to Qualcomm HS-USB QDLoader 9008”. I have used tools like boardiag but I get the followin message: “No response from the device. Check PMIC first and if still boot problem, replace AP.” To look at this thread: http://www.androidbrick.com/unbrick-recover-your-dead-lg-g3-g2-all-variants/ ... but report that it is not compatible for ATT and Tmobile variations. I currently have two virtual machines: Window xp 32 bit and Ubuntu 15.04. My client OS is 8.1 Window 64 bit.
I will be very grateful if you can help me to find a solution or can show me which is the correct way. I've been several weeks looking for a solution but I have not been able to fix my cellphone. I hope that my computer still recognizes it.

Hello,
I will try help you, first of all you must to change the Qualqomm mode in your phone, namely change usb LGE Androinet by QDloader 9008. For this you must remove the battery from the phone, open the phone and use copper cable or tweezers and you must to touch two points on the mainboard in order to force Qualcomm mode on your phone. I have attached photos to guide you in this process. You must touch two points (without battery) and connect the usb cable to the computer. You'll hear a sound that indicates that qualcomm is active otherwise could see a battery warning on the screen. If this happens, you must disconnect the usb cable and repeat the process.
The second thing you're going to do is install the drivers appropriate for Qualcomm mode. Please follow this thread: http://www.droidsavvy.com/unbrick-qualcomm-mobiles/
This is the download link for the drivers referred to the post: http://forum.xda-developers.com/attachment.php?attachmentid=3261089&stc=1&d=1428980071
Now your computer will recognize the cellular in the indicated mode (Relink HS-USB QDloader 9008).
The next step is to use the Boarddiag tool in this post but in the root folder, place the file sbl1.mbn which is located in the folder that you extract the file TOT.
I am currently uploading a package that includes bordiag tool, sbl1.mbn file, and TOT file extracted. When the upload is complete, I could tell you what is the download link, this contain the version of Boardiag that will work in our model. Currently my phone lg g3 D851 (chip MSM8975AC) was revived.

Good morning, please try downloading this package;
https://mega.nz/#!5lRGUZqZ!HZXaf4SP_PtuPEkg0ycdWXZP977_lBdVVqkI1P8DVtU
I'm not sure if it will work for your model, please performs the tests at your risk. Let me clarify that this is the same boarddiag version , only I try added the files needed.
Within the. 7z, there is a file called "TOT Extract", please extract it and open application BoardDiag. In the section "Target Dir" choose the path where you extracted the file.
Please inform me as it was with the tests.

Thank you SOOO much for your help so far.
I installed Qualcomm Drivers and touched the points and it connected.
But it says that the Drivers are blocked due to not being digitally signed.
And it's showing up in Device Manager as "Qualcomm HS-USB QDLoader 9008" with an exclamation point.
I am posting screen shots.'
You didn't have this issue?
What steps do I do in the BoardDiag exactly? Just add the directory with the file and hit start?
@mxpxboi it seems you're using windows 8/above, you have to disable driver signature, here is how to do it https://learn.sparkfun.com/tutorial...abling-signed-driver-enforcement-on-windows-8

Does your PC recognize your phone as Qualcomm HS-USB QDLoader 9008 or something else?

If PC doesn't recognize your device as Qualcomm HS-USB QDLoader 9008, you need to JTAG your device, or short pin.
Information about short pin;

Device will not turn on LG G3 D855 32GB

Hello everyone.
I need your help.
My Device: LG G3 D855 32GB
The device does not turn on, the only thing that appears is because when I connect the device to a PC, I see a driver installed:
RELINK HS-USB QDLoader 9008
I read guides on site here, and I'm trying to order
I downloaded the software BoardDiag 2.9
I downloaded the files to the appropriate TOT
I extracted the files by instructors on site.
I opened the program and I followed the guide and it seems to me an error
Download mode is enabled Mode,
I quickly disconnects from the computer and reconnect the computer and then the moment I am unable to do a test and the results are:
AP CHECK START = PASS
EMMC TEST START
FAILED TO OPEN PARTITION FROM EMMC
TEST ABORTED !!
I tried a lot of tutorials but I can not, it always seems the device is in Download Mode
What can I do more?
Please your help,
Eliran
If you go that way, you will need bunch of other stuff. Here is the link
http://open-freax.fr/guide-unbrick-your-lg-g3/
It is a good thing that your PC recognises phone like that.
But first be sure that You can not enter download mode or recovery or even fastboot.
And please say what did you do to make it like that? Wrong flash?
If you CAN enter download mode than you can flash kdz or tot files from there. Easiest way is to use LGUP but you must be careful if you want to try.
The phone fell

I went through all the steps I found at:

I set up the software the guide and I got an error:

I changed the parameter Read / Write »to« Erase
And again I got the error:

Then I try again, click Start, open a window and write in English and Chinese
Device DLOAD mode
device was not found in dload trying flash peogrammer
I click OK, the window closes and then when I press Start again, the window reappears.
Only when I disconnect the USB cable from the computer and the author briefly again then I’m able to do the test, but he failed.
FAIL on the EMMC test
The device always is in Download Mode and appears port:
RELINK HS-USB QDLoader 9008
My component can not be right at all and it always is in Download Mode?
I did not do short the guide, because the computer also detected me.
It has always seemed stuck in a download mode.
There is another option? Short elsewhere as will enable progress?

I am exactly in the same situation. Have you found any solution so far???? My phone suddenly stopped working and didn't boot up at all first and then I used the LG Flashtool to install original TOT file and all went well. I forgot to close LG Flashtool and it started flashing again. LG Flash tool restarts the phone at about 80% and then it failed at that point and since then I am having this issue.................
Any solution???????

1. You need to do is to check the latest version for your phone here by entering your phone's IMEI code.
2. Keep in mind the version and country and download the KDZ file you need.
3. Install LG drivers on your PC.
4. Go to this thread and from the section How to flash ROM KDZ Method start from the 3rd step.
This video shows how to get into Download Mode.
Then you have to root your phone again.
good luck

Hi, mirko0. We have the same problem and we need to do the same procedures to find the solution.
As seen in the following links:
http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
http://arena4g.com/forum/threads/unbrick-hard-unbrick-d855.7/ (Brazilian portuguese tutorial)
http://open-freax.fr/guide-unbrick-your-lg-g3/
You'll have to open up your phone (seriously) and make a short circuit in the board. Than, your PC will recognize as Qualcomm 9008.
Do not forget:
Install the x32 or x64 drives
If x64, do not forget to disable drive check
If windows 10, do not forget to reboot in advanced mode and disable drivers check
Everytime the phone reboot, you'll need to make the short circuit. I know, a pain in the ass.
You'll need the MBN folder of the Lollipop or Marshmallow. This is our actual problem
I haven't found the MBN folder of 6.0(v30) or 5.0 (v20), just v10. We'll need those files to proceed.
I finally had to send my phone for repair and I have repaired under warranty, soon expected to return repaired
