Hard-Bricked E971, Help?

After flashing the wrong kernel, my Rogers E971 is hard bricked. Cannot access download, fastboot or recovery mode. ADB does not recognize the device. It was showing up in device manager as QHSUSB_DLOAD, I found the drivers and installed them, and now it shows up as Qualcomm HS-USB QDLoader 9008 (COM9). I've tried configuring QPST and using eMMC Software Download App, but everytime I click Download it gives this error: "Image Download Failed. Cookie(if present) not recieved."
Aside from JTAG repair, do I have any options?
Any help would be appreciated.
Thanks

Search for "TeenyBit for Lg Optimus G" in google. Youll easily unbrick your phone there.

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,
Eliran

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???????

LG G3 D851 stocked in HS-USB 9008 after installing D855 KDZ 6.0

I'm unable to enter download mode or turn on the phone after after installing D855 firmware in ma d851, my computer recognizes it as a Qualcomm HS-USB QDLoader 9008 without short circuiting. I tried the BoardDiag method, but I get "Failed during loading flash programmer".
And when I use LG Flash Tool I get "Model Information Check Fail!"
I really need help!

You bricked your phone. You can not flash a different models software. If you flash a ROM it has to be for the d851 not the d855 or any other model as that is the model of your phone (d851).
Lg g3's have different hardware in each model.

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
