I no longer use this device, so I'm not aware if other users had the same issue like you.
First, did you try searching this forum for similar issues?
If not, it might be a better good place to start.
Second, please explain better whats happening to your phone:
Can you turn it on? If you can, what do you see?
Can you enter recovery mode? (volume down + home + power)
Can you enter emergency mode? (volume up + volume down + power)
Did you try flashing stock firmware with KDZ-flasher?
What ROM did you try to install? Did you check the ROM's page in these forum?

It's very problematic that you can't enter your device into emergency mode.
I think the only option that is left regarding software is to uninstall all of the drivers that are already installed for you device,
installing the latest drivers from the official site, and then try to use LG Mobile Support Tool to flash stock firmware.
Other than that you can only send it for a hardware repair

Maybe try what @kien_vip suggested.
And maybe try flashing the right stock version with KDZ-flasher.

Hey,
When i say download mode i mean (Remove Back Cover and Battery>Plug in USB while pressing Volume Down Key!)
As far as i guess we can enter emergency mod by pressing both the volume keys and power key at the same time.
I tried using KDZ but at some point gives me an error of WParam and LParam as I posted above.

Yes, you're right - to enter emergency mode hold volume up + volume down + power
When you're inside you'll see on your screen "EMERGENCY MODE" on a yellow background.
Only the use KDZ-flasher or the lg mobile support tool.
If you're indeed in this mode, then try what @kien_vip suggested above.

Before entering emergency mode you should remove the battery for a few seconds. Place it back into your phone then enter into emergency mode. Hope this could help you.

Lg update tool uses baseband as the only check whether your device has the latest update. This means you will get the update if you use an older baseband. However, you should try emergency option.

Thanks To All Of You Guys Problem Solved!
Took It To Local Repair Center And Using RIFF BOX JITAG They Solved It!
It Costed Me INR - Rs. 600 Or USD - Around 10 $!

solution I tried:
-factory reset
-ROM reflashing
-clearing data and fix permissions via cwm recovery(this one fix the gapps and com.android force stopped)
any suggestions ....

STUCK at LG Logo, NO Download mode..Please HELP!!

hi all,
I have posted my G2 problem in another thread but was hoping more people can see it and help me...
PHONE Stuck at LG Logo after power up.
NO Download Mode,
here goes..
Believed I was conned... and this could be what happened to my LG G2 'D802':
my mobile is actually a D801 phone (motherboard) NOT D802 but loaded with D802 ROM
Phone was flashed (by me) with D802 ROM to remove error "Unfortunately, the process com.android.systemui has stopped" caused by corrupted Build.Prop system file during some editing.
touch screen error after new ROM was flashed (tried many diff roms), likely due to incompatible phone settings.
unable to flash D801 kdz since the phone was configured to 'D802', incorrect model detected while trying to flash.
managed to get a D801 TOT file that can resolved the incompatible model issue
Flash completed, phone rebooted..STUCKED at LG LOGO!
pressed Vol+ and USB cable, cannot enter download mode...stucked..
Factory reset using hardware keys, same problem..
please help ! any suggestion/s would be greatly appreciated!! thank you!!

His download mode is not functional.
When in factory reset - connect to pc(does it throw errors or add a new device?)
If yes..then - read this
If no then still read it.

Can you plug your phone and check that your phone is not detected in device manager?

Brother I had the same problem yesterday and the pc didnt even detect the lg g2.... The thing is just do like I did listen carefully.
1 / Download LGMobile Support tool and install it quickly
2/ Open that program and click on install drivers ( when drivers are installed just go to the right top corner you will find an " OPTION ' click on it >>> And then click on upgrade recovery and do the process it says until it downloads and finishes )
3/ Go to the phone and enter Dload mode by pressing one the volume UP button and plug the usb cable directly to your device
4/ When the process will be finished you will have your phone healthy ))) and please do not unplug the lg g2 during the process

Ok so what you are going to do is to press the volume up button and connect your usb cable. After that you should be in download mode. Follow the instructions of http://forum.xda-developers.com/showthread.php?t=2432476 and i suggest you would choose the kdz method. Good luck

Holding volume up and power doesn't go download mode? You can try the SRK tool just download it. If it doesn't work you need the boarddiag method just search it here. I hope it'll be fixed soon.

I killed my 802 flashing CM13 onto it.
LG logo would flash up, no download mode but I could boot into recovery. However the phone wasnt seen in windows and did the multiple partitions thing a few have mentioned.
SRKtool fixed it, theres also a guide on youtube on how to use the software.

First of all power of your phone by long pressing power button until screen light goes off completely
Then keep pressing volume + button and connect it to PC via USB cable. [DOWNLOAD MODE]
Now you must be in download mode, simply flash stock firmware.
If you can't enter download mode then you might be in fastboot mode.
here are some threads..find out which one is related to your problem follow instructions carefully.

Thank you my friend for all your answers. In substance;
I can't open my phone. (Staying at LG logo screen.)
I can't do "Hard Reset" with phone buttons. (Because of "boot certification error" screen.)
I can enter "Download Mode" but I can't loading any .KDZ file with Flash Tool. (Stuck at %2)
My computer can't see my phone when I plug that.
Very hard situation. :crying:

I can't open my phone. (Staying at LG logo screen.)
I can't do "Hard Reset" with phone buttons. (Because of "boot certification error" screen.)
I can enter "Download Mode" but I can't loading any .KDZ file with Flash Tool. (Stuck at %2)
My computer can't see my phone when I plug that.
Very hard situation. :crying:

Reinstall LG drivers and PDA
then connect phone with PC in download mode.
open device manager and search for 'COM ports' list if you see your device there then you are ready to go.
If your device is not there then search under 'Other devices' and manually install drivers.
If you can boot into download mode and still you can't see your device in your PC then it's not problem with your G2. It's your PC which is causing it all.
Try another PC.

I reinstalled LG drivers, and i can see "LGE Android MTP Device" in Device Manager and it has no problem. (There is no yellow exclamation mark) But still, my computer can't see my phone. And i tried install stock rom with Flash Tools again but i did not work. Stuck at %2 again.
