Try reflash the phone using the unrooting method mentioned in
thread (LG Optimus L7 Dual P715 (Rooting,Unrooting,Flashing) search for it if you cant find it.
Just download your stock KDZ file via the link in that thread.
Download the software in that thread.
then:
0.Restart phone in emergency mode= hold the volume "down" and insert the USB cable(When phone is off)(Will Have Yellow Screen)
Install msxml
1.LG Drivers MUST be installed.
2.Plug The Phone in Emergency Mode.
3.Open KDZ_FW_UPD.exe
4.In Type Select 3GQCT , In Phone Mode Select EMERGENCY
5.Select the Stock Firmware KDZ and launch update.(Download LINK Given Above)

Did you solve your problem?? I am having a similar problem. I cant see LG logo. All i get is a blue screen which fades away. KDZ program gives an update error.Pls help..

I had the same problem...
1. So first you have to turn the phone completely off.
2. Then hold down the volume down+power until the LG logo is shown, let go and then immediately hold down same buttons.
3. This will bring you to a reset screen. Go through the reset process
4. This will bring you to the recovery
5. I installed a backup or try installing a rom you have on the phone
If any questions just ask. I know how stressful this could be

what is KDZ EMERGANCY MODE?

When you are unbricking it through the method that didn't work for you there is a KDZ Emergency mode that you can check. When I had the same problem as you did I just did the method that I posted above. Not sure what will happen if you do use the KDZ method.

Hi, I'm facing the same problem.
My phone only shows lg logo.
Thanks for your help

Turn off your phone by hold power for few sec. Now hold vol- and power, when device will show you LG logo, then repress power button, but vol- need be hold non-stop . U'll see for a while white screen, and factory reset, now press 3 times power button, it should show recovery. Now search adb sideload and install by sideload philz recovery cwm. If u'll finish, reboot recovery, then wipe data/factory reset and wipe for install clean rom. Now install by adb sideload CM11. After this ur phone should boot, and show system, u should able to plug usb now and put stock rom to sd. Check my solutions. It worked for me and my phone i alive

You had a lot of luck..the first thing you have done is - you flashed the wrong kernel.

No luck, every g2 will stuck by wrong kernel flash, but ofc if it is also for G2 but other variant.

You flashed also the wrong files after

D800 Boot Certification verify

i have an LG G2 D800, sometimes when i plug it to charger it turns on for a few seconds and shows the boot certification verify error along with the LG logo, then the screen goes black and cant do anything, pc doesnt recognize it.
i tried going into download mode (hold vol+ when connecting to pc) but nothing happens, sometimes it just turns on but show again that Boot Certification verify error and then the same black screen... Pc doesnt recognize anything (not even that qhsusb_bulk in device manager)...
what can i do?

Can you get into recovery? I literally had that same error today.

I know exactly what you are talking about hmm...
I was gonna suggest if you can get in recovery you could flash another rom and the problem would be solved, but its different in your case. You said your computer doesn't recognize your phone as well? I would assume you have the proper drivers for your device.
If you are able to get into download mode I suggest you use this guide: http://forum.xda-developers.com/showthread.php?t=2432476 to get back to stock..
I am not sure why you aren't able to get into recovery, but that's my suggestion. What did you do prior to this error popping up?
If all else fails then I would contact LG and try to convince them to send in your phone for repair, just a thought.
I've done a motherboard replacement on my G2 and in that case it was totally hard bricked. It is not a motherboard error so you would not need to go there.

go into download mode and use TOT or KDZ and flashtools. good luck
you said AT&T d800? i used this.
http://forum.xda-developers.com/showthread.php?t=2663369

Okay, heres the thing
I was able to short motherboard and got 9008 mode, used the BoarDiag method and it installed everything. But now, everytime i try to boot into download mode, phone does get into download mode but shuts off after few seconds.. So i cant install ROM from LG Flashtool, what now?
edit: now everytime i disconnect battery, connect it again, and connect it to pc or wall charger, it stays for a moment at LG logo and turns off, but cant seem to get to download mode... tried disconnecting batt and connecting again, then hold vol+ while connecting usb and it stays again awhile in LG logo, but no download mode, it just turns off again...
edit 2: Well, now it doesnt show Download mode for a few seconds... if i keep pressed power button for aroun 30/35secs and connect it to pc, it just shows LG logo for like 10 seconds and turns off, nothing else, not even doing the power button thing and keep vol+ when connecting...

okay, heres the thing now:
i used BoarDiag with d802 files and could get to download mode to flash d802 firmware TOT. it boots to lg logo and shuts down after few seconds.. then i tried the same with d800 TOT, and it does the same...
with d800 TOT sometimes it flashes an android green logo with some loading lines under it for like 3seconds and shuts down

Hello guys.
I was using Fulmics ROM, it was ok, but I wanted to switch it back to LG G6 stock
https://forum.xda-developers.com/lg-g6/development/rom-eu-lg-h870-20a-rom-t3794503
I mistakely went to this page:
https://androidfilehost.com/?w=files&flid=272154
and downloaded all these files, then I put them in SDCard and ran TWRP, then I wiped all and installed each of them. I thought they were android files, but no. My phone is now stucked in "welcome to Fastboot mode:", I can see and controll connected device on Fastboot, but not ADB ("error: no devices/emulators found"). Now I cant run system, cant go to recovery. Im doing that "volume down+power button" then releasing and again pushing power button, it asks to wipe all I choose yes, then again yes, but after that it should boot into TWRP but no, it goes again to "welcome to Fastboot mode:"
I know guys, I'm really nooby...
Please give me your help hand.
Thanks.

Try to enter download mode and flash stock kdz of your G6 model with LG UP and UPPERCUT, or try with the update error part of LG bridge. This should solve the problem. Search a bit in this forum and you will find how to flash with LG UP.

Discharge the phone completely or turn it off and connect to the usb to the pc while pressing volume up button. Is the only way I know now to do it.

I used "TOOL ALL IN ONE" programme, that flashed me a Melina TWRP and it works! I had some errored system and data parititions but I think a repaired them in TWRP, so Im installing back Fulmics. I will write after a minute.
