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,

Hello everyone
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
LGE AndroidNet USB Serial Port
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???????

Man, you are not the only one in this situation, I accidentally erased the f*cking 'tz' partition. If you are on linux, connect the phone to USB, the preloader will find that the whole of the data is messed up and put the phone into bulk mode. In bulk mode, the partitions of the phone is exposed as such so you can copy files into it. DONT DO IT WITHOUT RESEARCH. BUT I AM NOT SURE HOW TO RESTORE IT. If I get tz.img instead of tz.mbn, I will be able to 'dd' it. I dont think I can 'dd' a mbn file.

MIflash actually works , just b on new miflash version(which capable of switch 9008-9006 mode)...
it may gives errors many times...
tips to b successfull flash..
1. charge battery with external charger (most imp. )
2.if ur using pc, connect usb to motherboard usb port.( backside ports of cabinet)
3.try changing usb cables (sounds stupid but actually worked for me, as phone wont stay in 9006/9008 mode if usb signal drop)
dd wont work until u have access to fastboot/adb..

another way is make deep flash cable..
dnt wrry its very easy

HELP!!! Hard Brick Hydrogen

My phone is hard bricked. No LCD, no charging LEDs. Only showing up in EDL mode as Qualcomm Hs-USB QDLoader 9008 in the device manager. It happened when I tried to install the latest MIUI 9 weekly rom 7.9.15 from xiaomi.eu. I've spent the last few hours trying everything I could find. I can get MiFlash to see the device but I get different errors depending on the version of Mi Flash. Ive opened the phon eup, tried with/without the battery, tried shorting the two pins on the mobo mentioned in this thread
https://forum.xda-developers.com/showpost.php?p=68205960&postcount=24
I've tried three different computers, windows 10, windows 7 both 64 bit. Disabled driver verification. Tried many different global ROMs but still get the following errors depending on the version of miflash:\
-cannot read from COM port
-Reached the end of the file. (0x80070026: ReadRobust failed)
-cannot receive hello packet
Bottom line is that the phone is in a weird state and doesn't seem to communicate properly with the miflash tool.
Anyone have any clue what else i can try? I hate to lose my beloved mimax!
Thanks guys

I had Nigel's lineage ROM running perfectly on my phone. I got an itch to Try out the new MIUI 9. Downloaded the latest ROM and then the latest Superuser. Installed both of them and tore up. The ROM installed fine without any error messages. While installing SuperSU the phone just died. it was plugged into power so not sure why the screen just went dark.

Is this screenshot real? Why are you using 8675_W00 device firmware files from the guide literally!? Use miui rom link I gave you for hydrogen...

You have a keen eye Nigel. Yes I messed up the first time and used the wrong folder. Afterwards, I tried this with the proper folder with the correct firmware from the link you provided. Tried putting it in root drive and renamed the folders so there were no spaces. Even tried a newer fastboot firmware but still the same result. Looking around on google, apparently the Sahara error is very common and no real solution.
Thanks again for your help Nigel.

Hi Nigel, I'm wondering if you or anyone else who feels up to the challenge would be willing to work on this phone? I can send it to you with a self addressed envelope. I'm willing to pay for your time. I have exhausted all options but nothing has helped. would be great to have my phone back . If anyone is willing to take me up on this, please pm me. Thanks

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.

1- install mi flash tool and Qualcomm driver on your Pc
2- open the phone (just remove the battery connector )
3-plug a USB cable in the device
4- short the jtag pins(you can find their location in this page www mobilerdx com/2018/09/xiaomi-redmi-6-pro-test-point-boot-into-edl-9008-mode.html
7-plug the USB cable in the Pc while shortening the pins
If you do these steps mi flash tool should reconize your device and you will be able to flash it

Thanks man! My phone is working properly again. Let me tell my story in this.
Never opened a device before this. So I decided to take it to the official service. Unfortunately they told me that the mother board was damaged and the cost to REPLACE it is the same as buy a new phone!
So I been forced to try fix it by my self.
A couple of latex gloves XD and don't ask how I did to short the points but it works...
Now I'm using my Daisy again and waiting for official Android Q !!!
