I tried using LG Flash Tool with H90120e_00_0316.kdz... it gave the connecting to server error. I had read that this is normal, that I should wait... I waited twice, overnight, and nothing happened.
Did you have success? if so, which version of Flash Tool did you use, with which specific kdz file? and what is your phone version?
Thank you for your input, I will try again using the KDZ I have.
This happened to me and I was able to unbrick. You have to get into download mode by connecting your phone to your computer and just hold the volume up button before it loops again. Then I was able to re-flash the kmz in download mode with LGUP.
What happened is I forgot to fully unlock the bootloader again after flashing the kmz. You have to do the fastboot portion as well (fastboot oem unlock). Then you can flash the tot file and continue the root process.

Your phone needs to be connected to PC for that to work. Check if you connected directly to onboard USB port and cable is OK. Also, check if you going in it right: full shutdown (preferebly with battery), hold vol-up and connect it to PC while doing it. It should show small frame with "Download mod" and some dots and go to actual download mode after it detectes connection to PC.

Also, you can try holding vol-up again, after download mode screen appeared. What kind of bootloop you area having, by the way? Is it just LG logo or something is writen in red there?

OK, I will start off by saying I have (nearly) completely screwed myself.
I have a P769 (TMO; does this mean BK?).
I followed this (http://forum.xda-developers.com/showthread.php?p=38677123http://forum.xda-developers.com/showthread.php?p=38677123) to root the device and successfully made it through (using V20D KDZ).
Then then tried to flash this ROM (http://forum.xda-developers.com/showthread.php?t=2335984). Unforunately, I did not have an unlocked bootloader and now I am receiving a Security Error at boot. Even more unfortunate is that I did NOT do a backup so I am truly in a bad place now.
I tried to run through the first step of rooting but the software will not detect the phone as being connected and tells me to connect the USB cable. I have installed the drivers that are in that post but admittedly I may have updated them after rooting.
At this point I only have access to fastboot so I am trying that method but I cannot find any system.img files to be able to flash the system partition.
What do I do now? Can anyone help me? I have exhausted every Google search and XDA search. I may be missing something but I feel I am in a very bad place now and need to get this phone back up and running.

I am running 32-bit Windows 7 Professional Service Pack 1. I tried flashing V20D_00.kdz (using the offline flash) as well as the V10G_00.kdz and V10E_00.kdz.
Using the offline flash method I constantly get the error of cannot connect to phone no matter how many times I restart the PC or phone and unplug USB.

All caps, correct.
Should I do fastboot and then run the offline method?
I did do the fastboot then tried the recovery phone option from the support tool.
I did find a recovery I made that included (for some reason) only the recovery and boot.

Don't worry about stock recovery it's useless, just flash ics xloader and uboot http://forum.xda-developers.com/showthread.php?t=2292828 option #5

I'll reboot and then try that again. I'll check back afterwards.
Should I do anything extra like start the offline flash from scratch as far as drivers? I'm not even sure where to begin in regards to what drivers/files to remove.
Thank you! Thank you! Thank you!
Now I just need to figure out the screen calibration.
Also, what can I do with this now? Do I need to unlock the bootloader to load custom ROMs without getting a security error?
Sorry for my lack of knowledge. My last phone was a Bionic and that was the easiest phone to root and add a ROM to.
unfortunately i find myself in this situation
gettin security error after what i assume was me trying to flash on a locked bootloader
anyway, i can't figure this out, the whole flashing fastboot and what not
i read through the readme and installed the drivers for the "other/unknown" device that pops up
this is what i try to do next
open up start.bat
enter 5 and hit enter
remove battery from phone (as instructed) and hit any key
boot phone into sw upgrade (holding vol up and plugging in usb cable)
device seems to be picked up and i see the "wait 5 seconds" (german?) and the image is revered horizontally on my phone
now after 4/5 seconds it says "waiting for device", which then i put the battery in
but NOTHING happens after this, it hangs at "waiting for device"
can someone please tell me what i'm doing wrong?
otherwise i think i'm left with a totally effed lg optimus l9

Odds are, you are doing nothing wrong. Check your android version, if you are on 4.2+ (JellyBean) you can't unlock your bootloader quite yet. Here is the thread you should keep track of at the moment http://forum.xda-developers.com/showthread.php?t=2277639&page=152

I've found that the process completes if you put the battery back in , right after you reconnect the USB.

Nope! I had to do a warranty exchange. I was copying the system image then I thought it finished so I unplugged the phone. May I tried my best to get the phone back but I could only get into fastboot mode, but hey lesson learned. Though I did see this tool that someone here was trying to use to flash bin and fls files in 3 minutes! But it only works for p790 Optimus black. Which sucks because I could get my phone into an inverted S/W upgrade mode (yeah I know it's on the real one) but it only lasted for about 3 minutes then shut down so doing the offline fix just took too long. I would get to about 23% install and the phone would just turn off. . so close! LOL
EDIT: YEAH got the phone to finally work! No exchange now, take that LG! Just kept trying there offline fix

I'm trying to restore my P769 to stock (Stuck LG logo), and getting nowhere.
How did you get the flash to work? What error did you get when the phone would turn off? How did you get the inverted S/W mode?
My phone only got to 17-20% before getting an connection error using the offline booth method, this was with both JB and ICS u-boot/boot/recovery .imgs from the P769 ROMs--should I try the steps in unlocking the bootloader to at least get to a bootable state?

How did you solve this? I am at the same steps, I get into mirrored software mode and then I attempt the offline fix. I have even started the offline fix early to save time. And yet it will only stay on for 2 and a half minutes or so and then shuts off. The farthest i have been able to get it to go is 41%. I have tried fastboot mode to try and send boot.img and it just says that it cannot find the boot partition. So it looks like my only option is the offline fix but it doesn't have enough time to complete. I have tried about 20 or so times how many tries did it take for you? Did you do anything special to get it to finish? any advice on how to get it to finish? Spent about 6 hrs last night trying to get this phone back up and running and this is where i am stuck. Its lame cuz i woke up to the phone like this it was fine when i went to bed. And was for months.
ok, I used pimp my rom and well one little setting in the GPU area caused it to blackscreen.. so I decided to just clear the phone hard reset.. but no luck.
so now im stuck, LG comes up and SW does.. but I can not get the PC to clear the phone it keeps saying usb disconnected please connect.., I was using the Metro PCS rom.. 10D I believe, but anyways anyone that can step me in the right direction would have my gratitude.. ive tried the lelus method.. and just not working right.. maybe its the drivers.. but I made sure all of them are installed..

Leave your phone on while performing the offline flash, don't put it in s/w mode first. Your phone will go into s/w upgrade mode on it's own. Oh and use my modified/hex edited 11th bin

OK. Two options to solve this problem.
1. You can use LG Mobile support tool to recover your phone. Load it from LG website select recover phone from menu.
or
2. Flash ICS u boot & x-loader via fastboot. Please refer to to fastboot tool at http://forum.xda-developers.com/showthread.php?t=2292828 after that your computer should reconize your phone in S/W update mode and you can flash kdz.

I mean in fastboot script by Lelus, there're option to flash ICS u-boot & x-loader. Did you flash it on your phone? Because on JB KDZ flash tool cannot detect our phone. It work fine if our phone have ICS u-boot / x-loader.

thats what i did wrong lol, thankyou so much!, it works again!!
So I recently wanted to load a custom rom on my p769.
Unfortunately, I tried to flash a rom without actually having the bootloader unlocked (thought i did?)
Now i'm forever stuck at the "LG Security Error" screen.
I can't seem to do anything else! :'(
The only other mode I can boot into is S/W update screen (holding volume up and plugging in usb cable).
I tried to get to another mode I read about (vol up + vol down then plug usb cable for "download" mode, to no avail)
Anyway, once I do get it into sw update mode, I can't seem to do anything either way, when i try to list adb devices, none are listed, when i try to use lg mobile tool, it never connects, when i try to use kdz offline update tool, it doesn't see the phone, it just keeps trying to connect, the log freaks out at "_IsConnectedPhone Call", and just keeps trying to "connect" to phone but can't
Am I totally screwed here?
What can I do? Any help appreciated!

You're on JB, right? KDZ offline flash tool cannot detect phone in JB. you have to flash ICS x-loader/u-boot then that tool can detect your phone. please visit http://forum.xda-developers.com/showthread.php?t=2292828
For LG mobile support tool problem, it need to download rom from LG server. Have you remove/comment 1-2 line that you add to hosts file? You said it never connect that mean it don't see your phone?

I've tried this as well, but I don't know if i'm doing it correctly
I installed the 'drivers' it needs (following the readme file) when it shows the "unknown/other" device (the part where you have to catch it in device manager).
After this, I run the start.bat, enter 5 and hit enter, i unplug my phone and hit any key, then i plug it in as it says and it does it's thing, then i wait for 4 seconds when it begins to say "waiting for device", i put my battery in and it just stays there, waiting for device
Can you help me figure this out? Am I doing something wrong?

i think i'm making some progress, thanks for helping so far!
anyway, i'm able to get fastboot on my phone (i think?), the screen on the phone shows the flipped LG logo and at the top right it says 2.0 fastboot (flipped of course)
but, what am i supposed to do here?
i see the 2 omap devices listed on my device manager
whenever i try to run the kdz offline flash tool (if i'm using the right one), it still doesn't detect the phone as connected, doesn't even try, just errors and tells me to connect to usb port and restart or exit
what am i supposed to do once i'm in fastboot recovery for my phone?
should i comment out the 2 listings i added to the hosts file? should i NOT be running shttps app? which kdz offline flash tool should i be using? (currently trying: UpTestEX_mod2_marwin.exe)

You should run start.bat and select flash ICS u-boot/x-loader for P769
When it finish, reboot you phone to S/W update mode and try to use UpTestEX_mod2_marwin.exe to flash your P769 kdz again to restore your phone.
Maybe I miss something about P769 model, please search in FAQ forum many people have this issue, and most of them have fixed it.

you need to start from the very beginning: First install omap4boot and then use Lelus tool to install x and u boot then put the phone in fastboot mode. Then you should be able to s/w upgrade for offline fix.

Did you use Lelus' fastboot to flash u-boot / x-loader? There is P769 ICS version in that script.
Did you try to use LG mobile support tool to recover your phone?

While running the script select fastboot hold the vol + button and immediately put the battery back and close the script(lelus) in ! will boot into S/W and LG device does pick it up now i need to charge the battery :| will report back if everything goes well
That won't work because you should have inverted sw upgrade mode which means you don't have enough time before the fastball ends. Crossing my fingers for you
P769v20h- 'tis the season to give thanks so push the button already!

it worked for me .i do get a inverted sw upgrade mode kdz or the lg support tool picks it up just fine as i cant charge the battery .but its definitely can be revived this way . why does fastboot last only 1 min for this phone tho ?
Were you able to flash it back? Fastboot is only for a few minutes because it's not real fastboot. This is only a mock program that will help temporarily. I don't think you can flash the full ROM with this tool but if you can more power to you!

Hi guys. I got the Tmobile LG G2 and it was running on Android 4.4.2 LG G2 D80110c. Then I changed the dpi by editing the build.prop via root explorer up but when the device reboots, it shows system force close and I basically cannot do anything. I realized that my TWRP recovery hadn't installed successfully and also I think download mode is not working. Computer recognizes the device when it is on... Can someone please tell me how to unbrick my device? Is there a way to install TWRP at the current condition of the phone? I think I cannot use lg flashtool because that requires the phone to be in download mode, while mine can't get in download mode...please help! thank you!
Edit: also when I try to hard factory reset the device it shows: ERROR: boot certification error and it gets stuck in black screen.
What I can think of is a way to manually install TWRP via adb or manually flash a kernel that supports custom dpi, but the only problem is that I don't know how to do that...

theres several things you could do.. try srk tools to try and fix twrp, or fix download mode using nuke download.. i dont know how to i just know theres a way to do it.. if other fails and it doesn not go into download mode then you must short circuit the motherboard.... then look at thread g2 hard brick fix..
here but try other first as this one you have to open phone..

I don't think my phone is hard bricked. USB debbuging is on and computer recognizes the device when it boots up. I simply don't know how to install twrp via adb commands or alternative methods ... or how to manually flash a custom kernel that would allow normal device boot up when dpi is changed.
