I have the same problem, could you find a solution?

Please help

You need to flash your phone's original Jellybean (4.2) firmware, it is the only way that worked for me.

[Q] Need some help! Bricked phone!

Aw man I need some serious help here! So yesterday I was following instructions on the android forum to get my phone to 2.3.7 and so I downloaded this fastboot ROM and flashed it to my GT540 but I later found out you needed to have a rooted phone in order to get into fastboot and everything in the OS from android forum kept crashing my apps (couldn't get Z4Root), so I decided to try to flash it to 2.1 with the LG Update Tool and it got stuck at 4 percent. I unplugged it and now my phone was stuck at the Vodafone logo. I used KDZ Updater to flash FranceOrangeV20C_Fastboot to it and it didnt work (some parameter error showed up). Now my phone is stuck on the LG logo and it isn't detected by anything! PLLEASE HELP! I bricked my phone!!!!
this happened to me before dont know about you but i would send it to lg.
Figured it out!
OK so in KDZ Updater change the phone mode to CS Emergency and go into Download Mode in the phone and then just flash
This is if you get errorcode: WParam:100 LParam:4008
mine was in a worst condition the phone will not boot in anyway
As your phone turn on there is always a way to save it
Don't worry, we all been there
Follow instructions properly anz don't be smart are solutions to avoid bricking.......now i agree send it to lg if still under warranty.
Sent from my LG GT540 using xda premium
go into download mode
connect it to ur pc
go into device manager and turn off android modem
use kdz updater english version and change type to 3GQCT-Smartphone(WM)
chose ur rom and run
That's what i did when my phone stuck at LG logo and the only thing i could do is go into download mode ^^
Hope it help

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).

Install LG PC Suite, the LG Mobile Support Tool and the LG L7 USB driver. Then try again. Make sure your phone is set on 3GQCT and EMERGENCY on KDZ.
Before you install a ROM, you're recommended to wipe data.
Bootloops can occurs in many ways, if you can logcat your problem, maybe we can help you.

Same happened to me I checked all solution but with no result finally I have to get a new phone but I came across a thread posted recently here is the link http://forum.xda-developers.com/lg-g2/general/fix-lg-g2-recovery-mode-download-mode-t2840458
I have asked the Op if this is possible for D802 international version.
Because most important for any process is that the PC DETECT THE PHONE which is not happening.
If you want can try and let me know as I am at place where i cant buy tools to open the phone.
ALL THE BEST..

Flashed wrong firmware on Lg g2 f320L

Hi,i really need help. My phone was working fine a few days back when i entered the recovery mode in f320L and deleted the system files. After that i saw the flash method and accidentally installed d802 firmware in my lg,not properly though,when the flashing was done on my phone,on my laptop it said "upgrade failed" while my phone was flashed. And now its touch is all messed up and restarts after every 5 seconds. It goes into download mode but not in recovery mode. I tried flashing the proper f320L files but its not working,it says "phone disconnected from PC" at 2%. My phone has been idle and useless for days. I would really appreciate some help. And since I'm from Pakistan i tried paying some geeks to fix it but they couldnt either.
