LG G3 D850AT Bricked and Reset but continues to become bricked - G3 Q&A, Help & Troubleshooting

I was trying to install TWRP on my LG G3 (D850) and somehow got it so it would only show up as a Qualcomm HS-USB QDLoader9008 Device on my pc with no screen on and no way to get to any DL Mode.
I followed the directions from http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/ and used the LG Smart Boot Diagnosis Tool (1.3.1) to get it back to be able to boot but as soon as I run the LG Flash Tool again and it resets I'm back to the no screen and only being identified as a "Qualcomm HS-USB QDLoader9008 " device via USB. I have done this 3 times now and still getting the same result. I rerun the Anti RollBack software and then try to flash again but it always does the same thing.
Is there something I am missing?
Thanks

LG G Pro E986 Stuck in boot loop, no recovery no download mode, Help

So yesterday i tried flashing super LTE lollipop and being the stupid person that i am i flashed the E980 version instead of the actual version E986 (which i found later by removing the battery :| )
When rebooting the phone the home button is constantly on while the screen backlight turns on and then off again and again.
No lg logo, no recovery and no download mode.
Only when i plug in the phone to my pc it detects it as lg androidnet usb serialport and not Qualcomm HS-USB QDLoader 9008 like in other threads. Can i still get stock rom back? help much appreciated.
Edit: Okay i don't know why but apparently when i pressed vol + and vol - simultaneously and then connected the usb to pc despite showing a black screen it actually was download mode because using Lgflashtools i managed to install stock jelly bean. And i thought i was full hard bricked :/
reserved.
mine is detected as Qualcomm HS-USB QDLoader 9008 but nobody has achived to get live my OGPro...
Have you found the required TOT file and DLL?
I am having the same problem with LG G Pro e98820c after flashing wrong rom and unplug USB during flashing process.
Now the phone is stuck at Brick qualcomm hs-usb qdloader 9008 mode. I have some tools such as Smart diagnosis tool, BoardDiag, Androidbrick, Qfil/QPST ....But I have no proper guide how to use them to unbrick qualcomm hs-usb qdloader 9008 mode.
Have you got a solution for your brick phone.
Thanks , Sho Thant.

If your phone is furbished, you have to confirm your. Model by opening and looking at the board.
You are flashing 855 firmware but that might be any other model.

Hard bricked F400L

Hi all
It all happens after the screen was suddenly froze and having to take the battery out.
When turned on, the phone had a red/blue led problem.
It was first solved using the LGFlashTool V1.8.6.527 to flash in the LGF400LAT-00-V10a-LGU-KR-MAY-18-2014-0 tot. The phone was reverted to the original firmware and was functional.
Then I wished to upgrade to the latest stock fw (F400L30c_00_1217) using LG Tool 2014. Unfortunately this buggy program prompted connection to server failed and the text was messed up with ????? in the pop up LGUserCSTool window. It was force closed by the system so the whole process could not be completed. I pulled out the battery again(which I now think that I shouldn't do) and after restarting the download mode was ruined.
I tried to fix it using the short pin method here and if rescued would re-flash the tot using the LGFlashTool.
The problem is LGFlashTool did not allow me to do it this time with Model Information Check Fail just like others in this forum https://forum.xda-developers.com/lg-g3/help/model-information-check-fail-t3163715
Having received the message "Model Information" fail, I thought it was due to the firmware version mismatch so I decided to give the LG Tool 2014 a try, again.
I was learnt to ignore the connection fail message to let it run in the background.
However, this time it ended up at around 65% and now the download mode has gone.
Each time the power+vol up combination ends up being detected as qhsusb_bulk, a.k.a Qualcomm HS-USB QDLoader 9008
Not sure if the pins were physically damage during the shorting.
I have a thought. Is there any tool to convert kdz -> tot?
I know there is one to extract the bin, dz from kdz but I need tot to use in the boarddiag (as I think maybe the v30c firmware information has written into the phone by LG tool causing the LGFlashTool V1.8.6.527 to reject writing in)
What is the boarddiag for? Is it performing the same as adb/fastboot to erase/flash partition?
Or are there any workouts?
Thanks for reading and helping me.
it's so weird...yesterday it was stuck at qhsusb_bulk mode
so after placing for a day, it was detected as ABD interface today
and it was booted into fastboot mode.
I managed to erase partition but not flash..tried fastboot boot twrp.img
it restarted with a black screen and this time was detected as lge AndroidNet USB Serial Port
have tried the lg flashtool but no luck
Followed by that, I had applied the short pin method to restore the partitions again..
afterwards, i could manage to get in qhsusb_bulk only...
lets see if it could be in ABD interface tomorrow
btw, any ways to fix the download mode by the fastboot method given the bootloader was locked?
I was finally able to reflash using the tot file
but after flashing the phone reboots into black screen with flashing blue/red led just like previously(bricked status)
the phone was unable to connect as LGE AndroidNet USB Serial Port too
therefore, the flash tool could not complete
any idea for a fix?

Nexus 5X Hard bricked?? No bootloader, no startup, Qualcomm HS-USB QDLoader 9008 HELP

Hi,
After I took a picture with my camera, my Nexus started to go into a bootloop. I forced it to shutdown by going to the bootloader and choosing shutdown. I later on wanted to start the mobile, but it would sometimes just crash instantly or show the google screen and crash. I tried flashing a 4 core boot image, as that might solve it, but instead it wouldn't boot either. I also had to flash a TWRP recovery optimized for the 4 core boot image. If I finally got into the bootloader, selecting recovery will just crash after a few seconds. I tried to flash the 1 core boot image, as I hoped that might solve it, but made matters worse. I cannot start it, nor can I get into the bootloader. When I connect the phone however, it shows up as an Qualcomm HS-USB QDLoader 9008. I tried LG UP as suggested, but that doesn't recognize my phone. I decided to try LG Flash Tool, but it will always fail..
I don't know what to do anymore, please help!
