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.

Yeah i will have to wait then can't afford the $175 deductible right now. Thanks for the help. I don't mind waiting just hope i can find a less costly solution know what i mean?
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;

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

Hi guys,
I made a stupid mistake:
I was overwriting aboot.img from terminal to solve "secure boot failed" error. I didn't have backcase installed and battery fell out.
Now, the phone is bricked or at least the screen remains black, no vibrating, no flashing LED.
Is there anything I can do to revive the phone?
Can you enter anything ? Download mode ?
IF nothing you have to force to qualcomm 9008 mode and use boarddiag to fix the phone
Download-mode (Vol-up while plugging in USB) does not work.
Do you think, I can unbrick it by using willcracker's method?
Is there anything I need to keep in mind? Can you give an estimation whether this approach will solve the issue?
Yes, both willcrackers and the link will fix it
If you somehow fail write here
uhm, it seems as if the archive is protected by password? Any adive on how to get hold of it or any alternative solution?
What's also a little strange: the file "androidbrick_G3_fix.7z" is above 100MB while the download of "BoardDiag v2.99a.zip" is around 7MB...
Do I need to dis-assemble the G3 to short the pins stated here?
I did the EXACT SAME THING. I guess we can be idiots together, right?
Unfortunately, boarddiag refuses to flash with some error about the AP and android_g3_fix fails for me (looks like it's working but does nothing).
If you want to try anroidbrick_g3_fix you can email the author for the password.
I'm at a loss as to what to do, I'm already in qualcomm 9008 mode with drivers...
Follow the steps on this post: http://forum.xda-developers.com/lg-g3/help/fix-marshmallow-autorec-hard-brick-t3284608
After i killed my G3 with TWRP (Autorec for LP) on MM i bring my G3 back to life.
Tip: Use a thin massive copper caple, 0,5mm, and put the other end on the top of the sim-slot for ground.
It´s easier.

I don't have TWRP though, will it work?
Didn't seem to. I've had horrid luck with BoardDiag though...
I'm not sure if it makes any difference, but my phone is a Verizon 32GB LG G3 w/MSM8975AC that came preflashed with 35b 5.1.1 (thanks, ,verizon) and has never seemed to respond to any of the downgrade methods. Hence me playing with partitions, flashing aboot to an earleir version, and getting into this mess by failing to flash sb1.
I'm willing to pay to get this fixed, but unsure where to go or who is reputable.
I have managed to shortcircuit the pins and get my G3 to be listed as "Qualcomm HS-USB QDLoader 9008" and a corresponding COM port.
When I start the "androidbrick_G3_fix" as administrator, the tool shows that "USB Status" is "not ready". In the guide it says:
if your driver is installed you will see your port, if not, youll see “Not ready” in little green window.

EDIT:
I've used BoardDiag 2.99a to flash different partions according to this source extracted from *.tot file.
Now the phone (obviously) does not boot and shows "Security Error".
Trying to enter download mode seems to work though as it shows "Download Mode" followed by "Firmware Update".

You need to do the short and connect the cable with the tool open first. Otherwise for some weird reason it doesn't detect the phone.
It appeared to work for me but did nothing. I hope you have better luck.

Just saw your edit.
If you can enter download mode, you can now flash a tot using any online guide for such, and in theory unbrick your phone.
As for me, still no luck.

Currently, I am flashing a kitkat kdz (D85510f_00.kdz) to the phone using LG Flash Tool 2014.
It seems to takes ages but is progressing nevertheless. After 30 minutes the tool says 14% whereas the phone says 5% on the screen. I hope the process speeds up a little...
Wish me luck

@ R-T-B:
Are you able to get the phone to 9008 mode? Have you tried using the plain BoardDiag 2.99a to extract from *.tot file and flash those afterwards?

But seriously, good luck. Sounds like you are in the home stretch.
EDIT: Yes, I am in 9008. Unfortunately BoardDiag seems to refuse to flash it with AP errors. I think it's an issue with the updated chipset Verizon uses on the 32gb model.

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

Can you boot to recovery? Should be the power + volume down combo until the logo comes up.
Alternatively,
Have you installed ADB and fastboot drivers?
Can ADB see your device when you're plugged into the computer? Perhaps you can get into bootloader mode through ADB if so.
Connect LG G4 to your computer.
On the PC, access the Android SDK folder (download it if you don't have it).
There, open a command prompt window by pressing shift + right click on any blank area.
In the CMD window, execute the command " adb reboot bootloader " without quotes. If you haven't enabled USB debugging, you may be out of luck.
Tried but not working
Hello, Friend Thank you very much for your time and efforts while typing this to help me out. I did but still doesn't recognize took the owner. Technically the phone is dead.

1. Point us to that dubious unlock app please!
2. Very very often an issue occurs because a user do not use the correct commands or important error messages are thrown and the user do not show. So please write EXACTLY what you do. For example the exact command to proof the connection (e.g. "adb devices") and the exact result. easiest and best way is to just make a screenshot of anything.
3. Another example is how to you try to get into download mode? There are some guides which do not work so explain what you do always helps others to help you.
I use the following method:
Pull out battery
Plugin USB cable connected to the pc
Press vol Up and keep pressed while putting battery back in place
4. To avoid driver issues you should consider to use FWUL ( https://tinyurl.com/FWULatXDA ) for anything else then kdz flashing (this requires windows)

Hi, Thank you very much for taking your time and energy to answer me. I used Z3x to Factory the LG G4 (T-Mobile) I wanted to flash it by downgrading before to see if it could work. this is how I break the phone with the downgrading. So now the phone is not recognizing by the computer as Modem when I plugged in, I see it only as External Drive.

I used Z3x to Factory the LG G4 (T-Mobile) I wanted to flash it by downgrading before to see if it could work. this is how I break the phone with the downgrading. So now the phone is not recognizing by the computer as Modem when I plugged in, I see it only as External Drive.

you cannot downgrade h811 it has antirollback. and in autoprime 20i thread says it bricks phone.. if it was on MM and flashed lower antirollback.
what is Z3x.???
So I am completely stumped.. I would like to perform this guide to unlock my bootloader on my LG g8 thinq the only problem i continuously run into is when i put my phone into EDL mode and connect it to my PC I check the device manager and it comes up as qusb_bulk_cid:xxx_SN:xxxxxxx I have tried everything i can think of to fix this issue... I have installed all of the latest qualcomm drivers, ADB drivers, USB drivers and nothing will correct this for QFIL to be able to pick up my phone and a port that gets assigned to it like (COM1) ect ect. I really hope someone could tell me what im doing wrong and or what im missing please. I everyone else get this qualcomm 9008 thing instead and I cant for the life of me figure out what is going on.

Haven't done this part in quite a while, but I think you just need to right click it in file manager, oops I mean device manager of course, and assign the appropriate driver to it.

I have attempted to do this and every time I do it says windows could not install the driver. I’ve also used a driver updating software and it said the driver was missing. Tried to update/install it and it did nothing.. just kept saying the driver was missing.
