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.

I followed the steps given on that thread
My pc shows new device found ANDROID. Device is not getting detected
But on this step in cmd
fastboot erase recovery
it shows < waiting for device >
i too got such problem.
while holding down back +Vol down connect your phone to pc .It will enter into emergency mode.Then your Computer might detect it.
Can anyone of u help me ???? My phone is still stuck with Fastboot mode
Basically on a windows machine you download kdz updater and uncompress it as it is a zip file.
Download from here.
This is what I did on an xp laptop.
I had to down load the drivers from the official lg site. when here you enter the code that is on the box the phone came in or under the battery.
Chose the your county and laguage from the drop down box at the top right of the dialogue box. Then from the middle you can choose the drivers. For some reason I had to find the files and click on them to install the driver.
Ok once you decompress kdz updater there are three seperate files to work with. 1. windows enabler. 2. msxml.msi 3.KDZ_FW_UPD.exe
You will also need to download the right file to restore with,You can find it with google.
Please check here the The_ERROR thread wich explains it very well:
[ROMS] Original LG Firmware list.
Install msxml now.
Now you have to boot the phone into rescue mode. On Lg Optimus One turn phone off even if it means taking out the battery.
Press power - volume up - back (this button is next to the home button).
Connect to usb now.Computer found new hardware and installed four drivers.
Then open device manager. Left click my computer - properties - device manager. You need to disable the lg modem driver. Left click on it and disable.
Now launch kdz updater. There will be a drop box on left set to 3gspt or similiar. on the right drop box set to diag. The long box just above the info box with a file at the side lets you browse to find restore file. e.g. V10a.00.kdz.
Double click the button below and let it do it's thing. Took 15min. My phone shut down and came up with an error at the last minute. Anyway I rebooted and all was good.
Everything was the way I left it. Just had to re-root.
My only real problem was getting the kdz installer to see the phone.
After installing the drivers restart pc. If it finishes quickly and just before saying finished it says phone not found try removing all phone related drivers including nokia pc suite and the lg suite and remove and reinstall the drivers.
Hope this is of some help to you.
Finally, Recovered my phone by flashing KDZ through Emergency mode.. No other method worked..

I had the same worries coz my pc did not detect my device at all..
I was trying to get pass the Fastboot mode.. But in the cmd when i tried to erase and re-install recovery it said waiting for device.. Luckily and finally after many tries i could enter emergency mode. Only then the phone got detected but fastboot didnot work there.. The Only way out was to Do the KDZ flash. I flashed the indian GB V20b and did a hard reset now. Flashed recovery and for now have left it with the stock rom..
I wonder now this problem arises due to custom roms.

this problem was cuz didn't perform the steps carefully.
This can called bricking but not fully . As it can be recovered.
Bricking is when your phone is as useless as a brick.
I've been trying to flash my p768 for JB V20A VIETNAM. i used V20A TELCEL, MEXICO Before this flashing.
So I started flashing the KDZ file, followed all the necessary steps and finally when the process is at 15 percent, flashing stopped saying there is a problem with communication between cell phone and pc.
So i did the workoaround, remove the usb cable and wait for at least 10 secs and reconnect, then waited for all the drivers to install. After restarting the whole process it got stack still at 15 percent. Now I cannot get out of Software update mode even if I remove the battery and start the device again.
also i use Following method. and it dosent work. and at 15 percent, flashing stopped saying there is a problem with communication between cell phone and pc Again.
method:If you were on JB, the phone won't be recognized on "S/W Update" screen by the offline method. You must use the online method :
- Remove the lines you put in your "hosts" file ("127.0.0.1 csmg.lgmobile.com" and "127.0.0.1 csmgdl.lgmobile.com") then reboot your computer
- Connect your phone (on the "S/W Update" mode)
- Directly start "B2CAppSetup.exe" : it should detect your phone
- Click on "Customer Support" then "Recovery Phone" (see screenshot on http://forum.xda-developers.com/show....php?t=2217710)
- Wait and pray... It can be long because it downloads the last KDZ file from official LG servers.
plz help meeee

The LG Update Tool can install latest drivers for you: did you properly install them ? If your phone can start in "S/W Update" mode, the online unbricking method should work, that's why I think you have a driver issue. Did you also try on another computer with another Windows version ? (the most "driver friendly" version would be a Windows XP at least on SP2).

you need to install fastboot drivers twice, once before you run the omap4fastboot and again after running it when you see that mirrored fastboot text
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.

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.

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

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
Insert battery more quickly

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

If you're running a Windows 8 OS, that's the reason it's not working.

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.
i Was on JB V20A and i installed the root and the CWM and try to put cwm. to check if bootloader was still locked well it does.
and now im stock on L9 Security error.
i can enter on S/W and tryin using the "UpTestEX_mod2_marwin" the Window enabler and the Http.exe to flash it but.
i try phone mode CS_emergency and emergency but when it start to check the phone it stuck on 15% and i can turn on the phone (thats the way i used to bypass the 15% and get with the instalation)
so what now? i can enter on S/W and Recovery Mode LG (This mode is for data backip at service center. after reboting press power key to keep using phone), still can do hard reset pressing volumen less home and power but nothing happen keep with the error.
i know while the phone turn on there's a solution.
my phone is L9 p768g
just don't view the post and ignore. :/
TY for all the view and the 900000 helps. nvm i solved ty to my fb L9 friends so... jodan

This case is very simple to solve. When you try to install a custom recovery with your bootloader locked, the phone system detects it and give you a message of an error in security, like in your case. To solve this, you'll need to reflash your rom. By doing this, the KDZ will reflash the original recovery and you will be able to access your phone/recovery again.
Step by step:
1. You need to install fastboot drivers: http://forum.xda-developers.com/showthread.php?t=2119090
Turn off the phone and remove the battery. Download THIS and exctract it to C:/. Open device manager in windows (Rigt click on Computer > Manage > Device manager) and connect your phone without the battery to pc via USB cable. Look in device manager for a new hardware connected, right click on it and click in update drivers. In the window open, select "Search for software driver in the computer" and in the window open select insert C:\fastboot\usb_drv_windows, tick the option "include subfolders" and advance. A pop up window may appear asking you if you do want to install the driver, choose YES and the drivers will install.
2. Navigate to the folder you extracted (C:/fastboot) and double click on start.bat. It will ask you for administrator privileges, just say yes.
3. Select your phone model (2 for P760, 3 for P765, 4 for P768 and 5 for P769). It will ask you to turn off your phone and remove battery. When you done with that, press enter. It will now ask you to insert USB cable with the phone without the battery and after 4 seconds re-insert the battery. Onde you done with that, it wil return a message to press any key. In this step the fastboot drivers may be installed again. Don't worry, it's normal
4. Remove the battery again, wait a few seconds and re-insert it.
5. Plug the USB cable in the phone with the battery in and let VOL UP pressed. The phone will enter in SW Update mode.
6. Follow THIS to reflash your rom. A list of avaiable official roms of different models is HERE. Remember to only flash roms made for your phone model or you may get some issues.
7. You're all done I recommend using THIS TWEAK, the phone becomes more responsive.
*** If you flashed a JellyBean rom (V20X.kdz) you can easily root with THIS and if you want CWM recovery use THIS ONE ------ REMEMBER NOT TO FLASH ANY CUSTOM ROM WITH THIS RECOVERY BECAUSE I'M CONSIDERING YOUR BOOTLOADER IS LOCKED AND FOR THIS REASON, YOU CANNOT FLASH CUSTOM ROMS WITH CWM, IT JUST DOESNT WORK!!!
Hope it help you
It works!!

Thank you so much. Yes my P769 BOOTLOADER definitely is locked and I can't even root it with all methods provided in xda, I use exactly your method to get my L9 back to life -- although I have to flash it back to original stock but at least it's BACK! Thank you so much. I saw some other people have the same issue but they can't make it work, hopefully your answer shed the light to ALL!
security error just use the lg pc suite and remove the lines or the host put recover via recovery and put your imei and it will start to download the stock Rom

I tried this method and the offline kdz method and here is the trouble I am having.
1. With this method I do everything perfect the device shows up for a couple seconds then it disappears so I cannot go any further.
2. With the offline fix I followed the OP to the letter and when I get to the part where I click on "normal web upgrade" I open it and start the upgrade as stated in the OP and nothing. I get the retry or cancel internet warning and ignore or close it and it will not even try pushing the file.
Anyway I have tried 2 different machines to no avail I am wondering if anyone has had a similar problem and fixed it?

Didn't work for me! But I tried another method and that saved me from a lot of steps.
Just install the driver and the latest LGMobile Support Tool
Start your phone in Software upgrade mode... Power + Vol up
In the LGMobile Support Tool click on Options and then Upgrade Recovery
Put your IMEI in the option that pops up
Wait for the miracle!
It worked for me ... NO MORE LG SECURITY ERROR

Sorry for reviving such an old thread, but oh well...
Your procedure doesn't seem to work with my device. Just to make sure we are using the same driver packages, can you post a link to the fastboot driver you have successfully used?
My L9 is always showing this "partition doesn't exist" error message, no matter what I try. Lelus's script seems to do the job and the phone is detected as a fastboot device, and can even be detected in LG Flash Tool (using a 910K cable), but flashing will stop after a little over 2 minutes, because the phone disconnects. During all of my attempts, the screen stays black.
Any hint?

Can you boot into recovery? We now have a custom recovery for locked bootloaders (and CM roms). If you can get into recovery, I would try some adb commands to mount the partitions.
No, no recovery. Just to make sure that I'm not doing it wrong, what is the key combination to boot to recovery?
I have also tried:
Code:
fastboot boot some_recovery_image.img
It says ok, but the phone just hangs at the black screen and becomes undetectable as a fastboot device, until I pull the battery. So, unless the some_recovery_image.img is unsuitable for my P760 (which may be!), there is something seriously wrong I think.
Or maybe I can try the same command with the custom recovery for bootloader locked phones... Where can I find it?

Your EMMC partition is wiped or fried... you really need a JTAG service or a Box like octopus because your L9 is Hard-bricked...
Thanks for your opinion. Yet, I still want to hear from others.
I'm running into more and more problems with the L9 as their me grows.
-Fastboot doesn't work under Windows 8.1 and 10, but under the now obsolete(for me) Windows 7, unlike my other devices, which are fine with Win 10.
-ADB seems to work, but requiring the device to be still able to boot.
-I always boot to recovery from within Android as long as the L9 ain't bricked. After a failed rom install, during which the sd card failed(could no longer write or be formatted afterwards, the last time stamps of files and folders were set during the failed install) I discovered a problem with TWRP(Artas182x's and Edwin's), which may have been present since a long time: Trying to invoke TWRP via keypress will brick the device!
So, if my P760 no longer boots, there's only download mode available, sort of the final line of defense.
-There's sort of a trick if even download mode fails: After a failed attempt unplug phone, force switch-off, if the phone is in brick state. Then switch on, force switch-off again, and only then attempt download mode again. And have patience while holding down the vol button, it might take up to 20 seconds for the phone to switch itself on into download mode. (A single forced powerdown will cause Fastboot NOT to work the next time)
But I'm absolutely clueless about the recovery issue, for now TWRP is semi-working, can only be accessed via Android, as long as the phone is fully working.
W/o Fastboot, I now have flashed stock rom several times and rooted it with Kingo rooter just to be able to run Flashify to install TWRP. If Flashify is the culprit for the TWRP issues, I could need a recommendation for a better working app.

Tried OMAP flasher ? It needs memory configuration file in order to work with our device
No, I didn't. I have sold the phone for spares.

I never needed the OMAP drivers and tools. As they are ancient, they will probably make even more problems with newer Windows versions.
I could by no means invoke Fastboot on this device with Windows 8.1 and 10, Seven worked. So you had to go for Download Mode instead to recover to stock rom, then root with the Kingo tool, then install TWRP via Rashr or Flashify, the most time consuming way to recover from the frequent bricks.
And the LG Flash Tool 2014 always needed several attempts to get the job done. The latest official recovery tool from LG works in D/L Mode, but will always download the rom image anew.
