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.

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

If PC doesn't recognize your device as Qualcomm HS-USB QDLoader 9008, you need to JTAG your device, or 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 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???????

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)

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.

LG G4 after flashing it went dead.

Hello, Friends, I wanted to unlock an LG G4 T-mobile for a customer with "Device unlock app"
after the flashing using LG Tools from z3x the phone now is a dead black screen. When I plugged into the computer I can hear the sounds it's connected but nothing is showing. Need help to turn it back on thanks. I can't even load in Download mode.
Thanks for any help.

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.
