make sure to have lg driver installed on your pc
press vol- and connect your phone to your pc, (else try vol+ + power + home and connect your phone to pc)
run KDZ and flash a new firmware
I'm sure that i have installed it... When i try the CWM recovery key combination, it shows me only the LG logo but not disorted like on normal reboot... I also tried to go into Modem Download Mode (Vol-, USB Attach) but it doesn't really work...
I also wanted to repair it by ADB Make Easy... but as i read somewhere else, to make it see my phone connection, i have to turn on USB Debugging... but i can't because i can't boot it :/
New thing... If I plug it into pc without a battery then it is connected (still cant see it) but it turns off after 1-2 minutes... ah and something else... If i plug it in, it shows me only the loading logo, nothing else... please help
I forgot about emergency mode combination and it workes! Tomorrow i will start flashing kdz. Thank you for your help. I appretiate it

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..
Hi
I tried flashing CWM Recovery on my new G2
but after flashing my phone boots and I see on the screen:
fastboot mode started
udc_start()
And it's stuck like that.
I tried downloading SDK and replacing recovery by fastboot commands, but my pc doesn't seem to recognize the phone.
After installing a usb driver I see in device manager that the driver is still not installed correctly.
I guess it's because my phone isn't loading, right? maybe it needs to be installed when Android is running?
I even tried factory reset (boot in recovery - power + vol up) but still no change
Please help me if you have an idea how, I only bought it last week and now it's bricked!
Thanks
additional information
my phone's model: D802
I downloaded the CWM image from here:
http://forum.xda-developers.com/showthread.php?p=46837114
my pc runs windows xp
thanks all

try holding the power down for 15 seconds. phone should be completely of now. now hold volume up while plugging in usb. this should get you in download mode. now read this thread. or maybe read this thread first.

thank you, but my phone is varrient-free, and I don't think any rom will work.don't see anything on the list that seems fit.
also, isn't there a way to only recover boot, and not wipe the rom entirely?
That'sa the reason why. You flashed recovery for Verizon and yours is D802 International. If you can still go to download mode, try here http://forum.xda-developers.com/showthread.php?t=2471370&highlight=brick or http://forum.xda-developers.com/showthread.php?t=2432476.
http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/ Here, choose only D802.

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
Hi, 2 years ago I try to change rom, I enter to recovery and I wipe data, dalvik and flash new rom from sd card as always, but after reboot phone doesn't want boot itself correctly, after show LG logo, phone stuck on black screen, I try enter to recovery and load backup, but I can't.. only black screen, in next 2 weeks I try to safe my phone, but nothing is working(I tried find help on polish websites about android). Today I found this phone in my closet, so now I know English little more so I try here, I plug phone to pc, after instaling drivers system detect "LGE Android MTP Device" and adb detect it as 5e331a device, so phone is not totally died. I search for more information,hard reset(power + vol- + menu) - nope, enter to emergency mode - nope . Its any way to unbrick my phone ?
Ps. I know, my English suck, so if I made any mistake, forgive me
Hi, again, I managed to switch phone intro emergency mode, from this point I can update phone from KDZ Updater. So problem solved
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
