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..

[Q] LG Optimus L3 - LG Logo Loop

Salut à tous,
Yesterday, i got a problem with my LG. I wanted to change the Rom and after i finished the procedure, i got and LG Logo Loop
Here a little video a made of the Loop : http://www.youtube.com/watch?v=1ZDgzhDNBb0&feature=youtu.be
Normaly, i can change the Rom again by Hard Reseting, but when i press the 3 buttons, nothing happens.
When i connect the phone to the PC, i don't even got the sound that Win8 does when a phone is pluged in, that means that the phone isn't recongnized by the PC, and i allready installed all the Drivers.
I can't enter Emergency mode, when i press the buttons, nothing happens too.
My phone wasn't rooted so i don't have CWM.
I tried LG Support Tool, KDZ Software update, but as i said, the phone isn't recongnized, so i can't do anything.
Some people on forums adviced Medusa Box, but when i launch the app, i got as a message : Card init failed ..
So this is it.
I hope someone can help me. The phone isn't mine, so i'm little afraid of this loop .. Some people on forums said that this is a Hard Break, others said that this is Soft break, other also said that this is a Dalvik Cache Loop ..
Anyway,
Thanx in advance

mAke sure you have install all LG Software on your computer, like usb driver the important one
then download stock rom for your device
and flash it through KDZ Software update,
Try instaling drivers on some win7 pc/laptop, then try to revive the phone via kdz, because win8 sometimes has problems with drivers etc,
Btw which procedure were you using to change the rom?

Download the stock rom (original) for your phone, must know which version there is a lot of version ( V10C, V10G, V10E ...)
Use Kdz updater, if the App crash check compatibility and choose windows XP, in KDZ updater use the mode 3GQCT and phone mode DIAG, browse for the stock rom in the KDZ FILE and click Launch software update.
When i flashed the stock rom i got the loop, so i tried to hard reset it and it worked for me (power + menu + volume down or up i forgot)
Try to hard reset before flash if it doesn't work, flash it.
Okay Thanx again mate, i'll try it now and tell you
Worked ?
Sent from my HTC Desire S using xda app-developers app
Sorry mate, i was busy all the week, i only had free time today.
Anyway, yes it worked
Thanx a lot !!
You're a life saver

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

[Q] Stuck on Bootscreen after flashing CWM (D802, 6.0.4.7)!

Hi there!
So I rooted my LG G2 (D802, 4.4.2, Stock, used ioroot) yesterday.
I intend(ed) to flash the Optimus G3 Rom, in the start post they recommended to flash cmw/twrp via "Simple Tool 3.2" (http://forum.xda-developers.com/showthread.php?t=2633941). After doing so (I used the automated version, not the manual one) I got STUCK ON THE BOOTSCREEN. There is a notification popping up for a few seconds in the left upper corner which lists several errors occurring:
BOOT CERTIFICATION VERIFY
SECURE BOOTING ERROR;
CAUSE: BOOTCERTIFICATION VERIFY
along with the following numbers listed from top to bottom: 710, 760, 810, 860, 910, 960 (I just noticed, the numbers can vary, but always follow the same pattern...)
after this message, the screen fades to black, I think it it is still running though, since it takes more than 10 seconds to reboot the phone by pressing the power button. I still have access to the button down/power button combo which leads to a factory reset setting, but it doesnt do anything for me since I still get stuck at the lg boot screen.
I
Atm I dont what to do! Enter download mode and flash something? I'm seriously kind lost here. So, thank you for your help!
Cheers
You flashed a custom recovery version thad doesin't match you phone ( example you flashed D801 recovery on D802 phone )

Thanks a ton!! Finally I can put a name on the problem (bricking...)- Ironically I never mangaged to get there in 3years of samsung flashing but got there within 15mins of flashing on the LG G2. I guess it's true what they say about samsung devices, as hard to brick as a brick...
I'll report back if it worked...
Weeell, as it turns out my phone isn't recognized by my pc (Win 7) anymore...I literally can't do anything. Any hints?
I can use the Tool, but it's always trying to connect to my phone without success. But when I connect my phone to the computer it opens a dropbox window (import photos) and several windows partitions, which it tells me to format...

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
