Can't unbrick Optimus l5

Hello, I ran into a problematic brick on my L5...nothing seems to work to unbrick it.
I followed the guides step by step using the KDZ updater and the appropriate firmware for my country, but it doesn't work.
How I bricked it:
I had CM10 installed and perfectly running for a month, so today I decided to attempt an overclock to speed the device up a bit.
So, I downloaded and installed the modded kernel, flashed it using CWM and rebooted the device. After that, the device just keep booting up, showing the LG logo and then a black screen.
Now, after trying to flash the old firmware after going into download mode it just stops on the LG logo with the flare (sun ray effect) spinning around the logo all the time...It's been like that for almost 30 minutes now. I attempted re-flashing it 3 times but nothing seems to work.
What do I do?
Thank you in advance.
It's bootloop. When I had L5 I had the same problem after flashing bricked phone via KDZ.
Do hard reset with key combination. It worked for me. Phone will boot up few minutes.

nop, it's like the device is dead,
Have you tried it:
Hold together volumn (-) + home button, then turn the power on
sorry for the delay, The phone was dead so I send it to the warranty and they send it to LG and then returned working so I just had to reroot it and update it again
so there is no solution to this brick???

This is what I get when I connect the phone by USB.
I just cant get into emergency, DIAG or emergency CS
KDZ the phone connects and then I get a message afterwards PHONE NOT FOUND.
everytime I install the drivers by LG support tool, it keeps giving me the option to install the driver, like I havent done it a hundred times over.
I think there should be a driver somewhere that can be installed but the only people that have this driver are LG tech's. So they can bill you after
send the phone in cause you rooted it. So the one billion dollar question is witch hero will find a way to unbrick this device. We only need a way
to get a driver to install and we are home free. Or maybe the only other option is throwing the phone for sale on internet for spare parts
HELP PLEASE HELP find a way to unbrick this phone. Believe me I flashed and bricked alot of different phones and there was a way out but in
with this phone it seems impossible!!
And there is no mode to put it in in because te volume buttons don't do crap, the home button also, the only time that the phone does show up is when windows tells me it has an unknown device that I for the love of god can't find a driver for. I tried SDK, the LG drivers, but no dice
Did you try emergency mode? (volume up + volume down + power button)
If not, see if you can enter it and then flashing your stock firmware with Software update [KDZ] 1.0.4.4 (KDZ-Flasher).

LG G2 Hard Bricked?

Hello friends.
Just today I tried to flash CM13 on my D802. I did. After that, I pressed reboot system as usual.
This is the weird thing: after pressing that, the phone showed the LG logo for a second then the screen went full black.
Now I can't boot the device. I have download mode available... No download mode though.
When I plug the device to my PC I get a ton of Windows Explorer prompts saying "You need to format the »something« in orded to use it". Like 10 of these.
Please help? I still have download mode available to me.
I already tried LG Flash Tools to return to stock but when it gets stuck on 60%. Then i get the message "the phone is disconnected from PC or USB". When I try the R&D Test Tool i get the message "Port or Serial not found"... Please help...
My Bad
Forgot to install LG drivers...

D802 Bootloop Issue after root [NEED HELP]

Hey guys.
I'm issuing a serious bootloop problem with my D802. I need help.
How things evolved, listen my story.
1- I was using Bliss ROM 6.4 , after a new update my cellular data connection lost. So I back to stock lollipop.
2- I back to D80230c with using LG G2 Stock Firmware (Go Back to Stock) http://forum.xda-developers.com/showthread.php?t=2432476 method. I got a KDZ file and I flash it.
3- Then I used [TOOLS] One Click ROOT+TWRP Recovery for Lollipop Stock Firmware http://forum.xda-developers.com/lg-g2/development-d802/tools-how-to-install-twrp-bump-d80230a-t3072186 to get root and TWRP.
4- Lastly, script broke on somewhere and my g2 stuck at bootloop.
- When I connect the phone to computer with usb cable, I am getting bootloop. [ LG logo keeps appearing in every 2 or 3 seconds. ] and it keep going.
- When I connect the phone to the charger with usb cable, I am still getting bootloop (lg logo thing) 5 or 6 times then I see Firmware update screen. Lastly, phone get stable and it holds firmware update screen as long as it charged.
-When I disconnected the phone from charger and connect to computer, it begin to restarting and bootloop continues.
Most importantly, my phone does not respond, if its not connected to computer or charger. I mean, it should connect to computer or charger with usb cable to respond hardware key commands. ( download mode, recovery mode, or hardware key control mode ) Btw hardware key control mode is korean language)
I tried LG PC Suite resolve update errors , I tried .tot and .dkz method for flashing rom. ( Device goes to bootloop when transferring data begin from computer.) These methods are failed for me. I did not try fastboot mode.
Maybe someone can help mw, I issuing this kind a problem in three years of android user.
Sorry my English :/

Meed help to setup my LG G2 from Scratch

Hello all,
Recently My LG G2 broke for no reason . I was playing music and then it just stopped working. Then it stuck at booting loop logo.
Then I tried LGFlash tools 2014 with AU Vodafone D802T30a_00.kdz. It started firmware update but there was some error came in and asked me to remove battery and connect to micro USB again and retry.
But It did not work and stuck at the firmware upgrade screen.
Then I tried using SRKtools_2.1_droidth.zip, and tried to unbrick it. but I think it did not work properly. I remember my phone is not rooted.
Currently if I try to start my phone I see only LG logo and then it turns off.
If I try to connect it to the laptop, it opens lost of different drives and asks me to format but doesn't allow formatting due to write protection.
I tried to root the device using SRK tools but it is not recongnising device or asks me to select device in manual mode.
Can some one please help me in this situation. I want make my phone back in Life....
THank you
AMoL
