Thanks, I've read this post and I will stop the screen that you place else, as if something was missing in the program or you must connect the g3 via RS232 serial ...

Hi. I just quoted what I read. I `be never been in your situation. I think you should keep searching.

What do you mean by you can't get the driver for Qualcomm 9008 mode?

I have the same problem with my LG. It has red LDI, but I think that's the battery problem. Try to change it.

if you unplug the battery, and put it back in, then hold the up button while plugging in the usb cable, can you get into Qualcom mode? I bricked my phone last week and i was able to get into qualcom mode that way. I then also installed the qualcom drivers and rebooted my pc. I used boarddiag by Willcracker and was able to recover my phone to a boot loop which allowed me to get into Download mode, which I was able to recover the phone back to stock.

Not working for me, still LGE USB Net. When I test point my G3, Windows show notification 'Not recognized'

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.

LG G3 D851 Dead/Bricked help would be grear

Howdy all
So! Like a idiot I flashed a d855 rom on it when twrp was working.
Now I get black screen no download mode no twrp nothing.
The quadcom pin out will not work at all.
The only thing I have working is in device manager it is showing as
LGE AndroidNET USB Serial Port (Com41)
Only phone I have so any help with this dam problem (if anything can be done) would be great thanks.

Do you get any flashing LEDs? up top the display?
At least factory restore works? Vol down + power?
Try to connect USB while holding vol up. If nothing happens but you pc detects it, press vol up about 5 times. It should get a Qualcomm port on device manager. At least for me it did...
Also you might want to install Qualcomm drivers: qualcomm hs-usb qdloader 9008 32/64 bit versions.
I would highly suggest to use a Windows 7 machine because for my d855 everything worked like a charm, unlike 8.1.both fully updated

Bricked my LGG3

Hello everyone,
so here's my problem:
Wednesday morning i took my phone out of my pocket and had a blackscreen. I tried to restart it and took out the batterie but i always got stuck in the LG Logo or a bootloop. Since i had TWRP and lineage OS installed, i tried to go into the twrp menu with the factory mode (power button + volume down) but after the "double yes" i always got a blackscreen.
So i went into the internet to fix it myself. I tried the "LG Flash Tool 2014" with the kdz. reset & the other Flash tool with the tot. reset. Both didnt recognize my phone. At this point, the only thing that worked was the download mode BUT not the recovery mode that usually comes after it. It just showed the download mode for some seconds and then a black screen. Later i noticed that my phone showed as a "qualcomm device" in the device manager, and the internet said that this was bad. So i used "Board diag" and "Smart boot diag" to fix it, but at the point where the device should have restarted, and the download mode should have worked WITH the recovery mode, i always ONLY had the 6 second download mode. After messing a bit with "Board Diag" i even got it to show up as LGE AndroidNet USB Serial Port in the device manager, which apparently was even more bad and only way to go back to qualcomm was to shorten the pins which i did. And it worked BUT now i was back with the qualcomm stuff.
So as you can see, i've prety much run i circles since wednesday... Iam now at a point where 3 different thingscan happen when I try to put my LG into download mode (volume up + usb cable):
1. Its recognized as a unknown device which is constantly connecting and diconnecting, so iam assuming my phone is bootlooping with a black screen.
2. The download mode icon shows on my phone and disappears after some seconds but my pc fails to recognize it.
3. Nothing happens and the screen stays black
When i only connect the usb cable, it shows a stuck charging icon for some seconds and then goes black. Connecting without a battery shows the "missing battery icon". I tried with 2 pc's, both having the LG mobile driver 4.2 and the qualcomm driver installed AND beeing in testmode. Both don't recognize the device. I also tried 2 batteries on my phone but it changes nothing.
I have a D855. And i know that my situation is pretty f*cked but maybe someone i able to help me anyway. Thanks alot.
