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

Thanks for the comment
The phone fell into the vehicle.
I know the phone is always in Download Mode
The software does not let me do anything and making phone download mode
I did not try to install KDZ.
And I can not open a setup KDZ because the device does not rise and there is no open port.
I only have the port I did above.

I went through all the steps I found at:
Now, let’s get the party started
I set up the software the guide and I got an error:
FAIL on the EMMC test
I changed the parameter Read / Write »to« Erase
And again I got the error:
FAIL on the EMMC test
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?
Thank you very much for your help,

Today I tried again to connect the device to your computer, the screen comes on suddenly.
And see the state of battery with a question mark inside a yellow triangle.
I did not realize also saw installed driver

I tried to re-install.
Now again became a black screen and the next thing happens:
When the device without a battery connected to a computer costing me
RELINK HS-USB QDLoader 9008
When I'm with a battery, it registers an unknown device.
When the device without a battery test again tried to do this EMMC component fails.

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???????

Brick - Mobile does not wake up / Black Screen / EDL Mode HS-USB 9008

Hello sirs, I hope you can help me.
I have a mi6 that turned into a brick. Hold the buttons to it to give restart / download mode or put it to load. He does not respond to anything.
However,
By putting it on your computer it recognizes you as Qualcomm QDLoader 9008.
I wonder if I can recover it yet. or unfortunately it turned a paper weight.

I tried to do this form, downloaded all the miui site drivers, adb fastboot and cualcomm driver.
How to run my flash with a last method with the xiaomi global mi6 I got the following error:
"Cannot receive hello packet Xiaomi Device"
The program tried a few more times and nothing more.
What can I be doing wrong? Do you have another option? because he is in what they call DeadBrick (I discovered this term only now, after searching the forums)

I know, i was there. Reboot your computer and start again.

I restarted and tried again.
I formatted and installed only the drivers and the error continues.
I tried with miflash 2015 until version miflash2017

I think, you device isn't in EDL mode. You open back cover of device. Make test point for QDL 9008. Then, you flash fastboot rom by Mi flash tool. It's very simply. I made it for unbrick my Mi6 several times.
See video here.

Is this the only way to put the phone in edl mode?

Yes, it's only way for Mi6, which is locked bootloader.

PLEASE HELP H815 HARD BRICK no fastboot, no 9008 and no recovery USU

Hi People,
I manage to brick my LG G4 H815.
The phone was fine and I flashed this https://forum.xda-developers.com/g4/development/rom-h-rom-g6-port-t3660459 after that my phone simply didn't turn on not even an LG logo only black screen but it does vibrate when I try to power it up. When I plugged it into the PC I get nothing t doesn't detect the device at all.
I tried the 9008 drivers and still nothing.
PLEASE HELP!
*edit: also forgot to mention also download mode doesn't work*

if it's bricked you can force it to qualcomm 9008 mode by shorting the test point pins then use qfil

Question [SOLVED] Bricked OP9Pro, can't get to fastboot, sahara communication failed

Seems like I succesfully bricked my OP9Pro. Tried to restore in MSMDownloadTool v4.0. Oneplus 9 Pro LE2123.
Phone is detected correctly in Windows device manager(QDLoader 9008, I get to EDL by holding Vol+ and Vol- buttons and connecting the cable). When I try to flash, MSM breaks on Sahara communication failed(FH: 258).
Qualcomm drivers are from Windows Update Center(I connect my phone in EDL mode, click Update and in optional updates section there is the needed driver - Qualcomm Incorporated - Ports).
What should I do?
I saw a python EDL workaround script, but I'm not sure if helps me or if it even works (saw it somewhere on xda, the only thing I remember that it was in some of oneplus's devices thread and the sript name was edl.py, sorry
Tried on one laptop(Acer Nitro< none of the ports gave a succesful result). Gonna try on my second(Asus ROG GL702VMK, it seems to have better ports connection). Gonna write an update message.
I can't get to fastboot, recovery, etc. Phone seems to give no signs of life, there is even no charging notification when the cable is connected(but maybe phone isn't turned off actually, not sure)

You need to click the box to "use lite firehose" beforehand running your msm. And change target to OS or EU depending on which one ur using

Thanks for advice, I got further but now it stopped on Param Preload with "Device not match image"
I use MSMDownloadtool for EU and my phone is EU version(LE2123)

So, I am kinda happy cuz I booted to system.
I used this guide(https://forum.xda-developers.com/t/global-us-unbricking-guide.4370463/). Used MSM Download tool with Indian f/w.
Then I tried to return to EU version, but I got the same param preload error. I used this version of MSM and it flashed successfully.
So now I guess the issue is solved. Thanks @Shooter7889 for ur advice with lite firehose

Uncheck "check sha256" for mismatch device issue. Or find correct msm. You're welcome. I had same issue after bricking my 9pro and not being able to run msm successfully.

edl Qualcomm 9008

Hi all
well in a nutshell a friend's good old pixel 2 xl finally had the issue of black screen and only qbulk being detected by the PC.
After a bit of googling i found a Qualcomm loader and some firehose files from github.
However it fails on with error sahara protocol cannot establish connection.
I read that maybe i needed to short pins on the board to go into edl test mode, but dont know which ones i have attached a picture
Any suggestions would help

Can't help you with the pins. I can however tell you that based upon my experiences with my Lenovo tablet, using Xiaomi's MiFlash software proved a lot more reliable than Qualcomm's tools when trying to restore the firmware through the low level interface.

i will give it a try thank you, is it the same way for xiaomi to short pins in order to get to edl test mode ?

I don't know.

Well, there has to be a reason that the phone ended up in this state.
My guess is a hardware fault, and if that's the case, you'll need to replace the motherboard.
Some phones can end up this way if you do something stupid while flashing a rom, but I've never heard about that on a Pixel.

If your device is not properly detected, because it is not properly in EDL mode, then, there's not a tool that can detect it or work with.
When the kernel refuses to start because of a failed upgrade or something, then the device enters automatically to Qualcomm/EDL mode, but the first you'll see, it is detected in device manager as QBulk or Qualcomm HS-UB-Diagnostics 900E, then you have to update the drivers to Qualcomm HS-USB QDloader 9008 to get it.
This is an example of my other device, by fortune my P2XL is working fine besides the bootloader can't be unlocked.

Hello, i think i installed it correctly tried on two different computers with one "unsigned" driver with the windows drive signature turned off and then with a driver from Microsoft's own website which is signed i still gate the same issue.
Tired with couple of version of QPST with the latest i found being QPST_2.7.496, tried with a couple of firehose files there is a github repo with most of them 8916 often pops up in google 2xl topics and one zip which was named 2XL had in it prog_ufs_firehose_8998_ddr.elf not sure if its the correct one :
ERROR: function: rx_data:246 Error occurred while reading from COM port
ERROR: function: sahara_main:982 Sahara protocol error
ERROR: function: main:320 Uploading Image using Sahara protocol failed
So i am stuck to this point now , ANY suggestions will be appreciated

To start with, the correct installation of these drivers is mandatory, otherwise, you can't advance further, if you have a message of success, then it's done, if not, you may redo the steps.
Microsoft doesn't own any of the needed drivers here. All relies on Qualcomm, it contains the lot of variants, from all of them, one is all you need.
If the issue is with QPST, I saw a QPST thread in XDA, just search for it.
