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.

G2 stuck in fastboot after update

Recently i installed rooting mods on my g2 d802 and enabled fastboot mode
Just today my phone popped up with software updates from LG and i installed and when it rebooted it now starts only in fastboot mode and i am unable to enter any other modes and i've tried following and looking for similar posts about this problem but nothing seems to be working for me.
Any ideas how to reset my phone to stock or to stop it from starting in fastboot? please help! Im one of those phone addicts and it feels like i've just lost a limb.
Regards.

[Q] Stuck at security error

Hi everybody!
I have Lg g2 D802 Baltics. Yesterday I tried to return to Stock KitKat via Lg mobile support tool and Flashtool, both of them didn't work, they just didn't find my phone in download mode. Then I decided to reroot and reinstall TWRP. The first was done and the second too, but unfortunately my phone restarted and got a Security error and LG logo and can't boot, just permanently restarts. I've already read a hundreds of articles like http://forum.xda-developers.com/showthread.php?t=2432476 . The method written here isn't working for me because the Flashtool just can't find my phone when trying to install a firmware. So, any program like Lg support tool and Flashtool don't find my phone, so I can't do anything with my phone to get it to work. I'm facing i real problem for me and i'm quite shocked. So, please, tell me what to do, how to fix my phone. I tried a lot of thins, nothing helped. What to do?

LG G2 Not Entering DOWNLOAD Mode

Hi,
I recently bought an LG G2 D802 European version. OS Kitkat 4.4.2
Plugged it in to update via LG PC SUITE from 20b - 20D.
After upgrade the device starts and goes baboons... Touch is not working properly, cant get it to factory reset, Cant get into Download mode.
PC does not detect it anymore. Can anyone please help me out here.
Thank you in advance.
Can anyone tell me how to flash fresh KDZ via LG FLASH TOOL without getting into DOWNLOAD MODE?

Problem Going back to stock !

HI There ! I own a LG F320L for sometime now. It came with Kitkat 4.4.2 installed and then i flashed it with CloudyG2 rom and have been using it ever since. For the past 1 month I have this strange touch screen issue with erratic behaviour and phantom touches. It has been addressed as software related issue and going back to stock has fixed some of the users problem.
Now to the main issue, I followed the tutorial of LG FLASH TOOL Method upto the point. Installed drivers and have downloaded the KDZ for stock kitkat but when I enter the download mode and LG flash tool begins to start it doesnt even verify my phone. It keeps stopping at 2% software extraction (sometimes 4%) and then a dialog appears saying Disconnect phone and remove battery and then again put the battery in and connect your phone and try. I have been trying it for many hours but it doesnt make any difference. I have used unrooter tool to unroot my phone for download mode. I have also tried the TOT method for going back to stock but no success. Whenever I plug in my device it appears in device manager but it is not recognized by FLash tool still. Please help me. I have TWRP 2.8.4.0 Recovery installed.
I am running windows 8.1 X64. The drivers install with no problem.
P.S I have searched all the threads regarding flash tool problems and download mode recognition. I didnt find anything helpful.
