So the story goes as this:
ATT G3 accidentally flashed a D851 rom... phone rebooted now its a hard brick
I have tried every method to restore it to stock (lg flashtool 2014 and old flash tool method, tried enter TWRP nothing happened)
My phone is detected as it were in Download mode, but it doesnt let me flash anything.
I downloaded the "generic" LGUP8794.dll and tried to flash stock D850 and stock D851, jeez I even tried to flash LS990 stock rom... same error every time.
Downloaded stock D850PR20A_01.kdz and tried to flash it through Flashtool 2014 and just getting error...
I'm really out of options now.
I dont have warranty so its out of question the "return my phone" thing.
Thanks in advance for any reply or suggestion.
PD: I get no "QHUSB" or "fastboot" mode either.
Try using a different usb port. LG flash tool hates USB 3.0 so use USB 2.0

I have tried with 3 different computers, one with XP, Win7 and win8.1
I never use USB3.0 unless its with a memory stick
Can you go into download mode??

No, No Download mode, but my phone is connected as it were in download mode.
My screen is good, I know cuz when i connect the usb without battery it lights up and shows an image of "missing batt"
No TWRP either
Any update on this? I just rooted my D850PR and then used AutoREC to install TWRP, then I turned it off to reboot but it never booted...it also lights up the display when connecting the USB cable without the battery but that's all it does

i cant believe there is no clear solution for the LG G3 brick.
There is a solution
I have faced this issue with my LS990. accidentally flashed D855 ROM then bricked. THere is a unbricking method which is very hard and you have to do it with patience.
Try this
http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091
You might want to short 2 pins of G3 motherboard. message me if this method didn't work.
Good luck matehttp://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091
I had that problem, flashed d855 rom on a d850pr, and it went into bootloop, but I just went into recovery, flashed a D850 rom and everything worked fine. I did have your problem once, but with a LG Optimus L2, I tried on windows 8 and 7 but the LGflashtool always stop with errors, until I tried on XP, i could restore it. (sorry for the english)

Hi im new to XDA Developers Forum, i just tried this Solution( http://forum.xda-developers.com/lg-g3/help/help-secure-boot-error-trying-to-boot-t3054977 ) and my LG G3 D855. Is in the same state as from User "DonnieDoezoe"
"Totally bricked my phone with these instructions Won't turn on anymore. Tried everything...only shows a trinagle if I connect to usb without battery."
Before i tried this. I had already rooted the LG G3 D855, and after these instructions i tried to reboot into recoveryTWRP( wich i flashed with flashify) i tried to reboot with Quick Boot (Reboot ).
After this my Phone doesnt work anymore and is just like in the state of a blacksreen( the phone is visible as LGE AndroidNet USB Serial Port(COM41), the only thing that shows is a triangle if I connect to usb without battery.
I searched for solutions the whole day and tried to unbrick it with the LGFlashTool by flashing the .tot file and .dll, but wont work because i cant enter to the Download mode.
I Hope some one gives me hint in the right direction on how to fix this problem, would much appreciate it.

Hello , I watched all the tutorials unbrick lg g3 with boarddiag , flashtools ..
But I can not repair my phone (probably because I suck :silly If I do this is to recover my data. My smartphone does not start anymore "boot verification failed" but it is recognized when I connect with USB ( Qualcomm ) . If anyone can help me in private or in any other way it would be very nice . thanks:good:

please help me cant start my lg g3 d855 32gb at boot its says "boot verification failed cause different hash" cant even go to download mode after some lg animation then notification lights are switching. this issue manly occured due to usb disconnected between kdz firmware flashing process.i used lg flash tool 2014 and mm kdz firmware any help appriciated and sorry for my bad english
Like a lot of people I have the eu version of the h815 and managed to bootloop it after following the garbage methods online for rooting .. I came here for help and found all the methods listed... lg up, lg flashtool 2014 etc.. the problem was that my phone just wasn't recognized by the computer, it charged well but that was it, lg bridge, lg up, lg flashtool.. none could find my phone.. I thought I was doomed to a soft bricked paperweight and even began contemplating the hundreds of pounds needed to purchase a new phone.. however after hours and hours of tinkering I cracked it and now have a working lg g4 again.
first off download and install lg up dll file
then install lg up but don't open yet
find and make sure u download the correct kdz firmware file ( I needed the h81520d file which I downloaded from storage cow as devtesters didn't work for me)
now head to your computer control panel and delete(uninstall) any lg mobile drivers that you see.
connect your phone through usb into download mode and leave connected
once that's done download the old drivers (4.0.4 I believe) and not the newest 4.1.1 or whatever it is now.
then open lg up and hopefully like me you see your recognized phone.
click upgrade (not refurbish) and click bin.. right of bin is the ... symbol.
hit that, choose your kdz file and voila.. let it work its magic..
DAMN IM HAPPY. HOPE THIS CAN HELP SOME OF YOU LIKE IT DID ME.
Hi guys,
Please bear with me as I'm new to this scene.
My LG G3 Cat.6 (F460L) is currently stuck in bootloop, can't enter recovery mode as well but it can go through download mode but my PC won't recognize it (tried different usb cables and tried it on another PC, still no luck). I made an error when I was trying to flash twrp into recovery but accidentally flashed it to boot (I was quite unsure about what I did but I think I flashed a wrong version of twrp for recovery and tried to reflash the right version but accidentally flashed it to boot, if that made sense). I was able to get into the factory wipe screen and after pressing yes it goes right into bootloop again. Was also able to get into another screen with turn on, turn off and cancel options but I'm not sure what it does because it's all in korean. My PC can't recognize my device right before this happened so I think that explains why it also can't recognize it while in download mode. I saw something about Qualcomm stuff but I'm unsure as to how it is done (the shortpin part) and i don't think my PC would even recognize it as it can't even recognize my device in the first place (faulty micro usb port I guess). Any fix that you guys can think of? Thank you very much!
