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

cant install fastboot drivers windows 10
Hello, Guys. So I did a stupid thing today - I was poking around in the build.prop in my v20d P769. I changed the value of a line concerning the battery, something like "battery_genuine" - My thought was that it was going to enable some sort of alternate battery notification or icon or whatever, I'm not sure what I was thinking.
Anyway, long story short, I rebooted after editing build.prop and now when the phone turns on it just says "use genuine battery - powering off" and shuts off. I had previously uninstalled CWM (getting ready to manually apply v20f) so I can't get to recovery to mount /system. I have been trying all day to get the offline flash method to work and the damn thing won't work half the time. I went through the thread instructions to install small server and edit hosts file - then reboot - when the loopback ip's are in the hosts file the test link on the thread (127.0.0.1:9002) doesn't work and neither LG application will work. If I comment out the loopback lines and restart both of them will open but neither of them will do anything useful. LG Updater tool just says I have the latest software and the UptestEX_mod2_marwin application won't flash anything.
Hoping someone can help me out here so I can recover this phone.
boot the phone in fastboot mode, don't know how to do that with your model though
use fastboot to boot into any custom recovery by typing 'path_to_adb_toolkit_files\fastboot.exe boot your_recovery_image.img'
if fastboot hangs on <waiting for device> install usb drivers
then pull off build.prop, change that field to original value and push it back into the phone
sorry mate, can't explain more detailed
Either flash ICS uboot and xloader in fastboot mode and unbrick it after, or if you can access adb, try sometjing like the following:
cd to your adb directory on your PC
adb pull /system/build.prop (in a command prompt on your PC)
Modify the file (it will be in the adb folder)
adb push pathto/thefile/build.prop > /system/build.prop (again in the cmd)
Hope it helps

Thanks for the reply man - yeah I can't get to adb, that was my first though so i'm going to try fastboot, only problem is, I don't know how to boot fastboot. Is s/w upgrade mode the fastboot screen (volume up + plug in cable)?
Also, would anyone mind explaining why the small server only outputs "file not found" when attempting to start up the flash tool? The only way I can get the flash tool to even launch is to comment out the loopback lines in hosts. lol man it's times like this when I miss motorola!
*Edit - In case anyone wants to help on this front, here is the output I receive from small server when trying to open B2CappClient or UpTest or even hit the test link in the offline flash thread:

I recommended removing all lg drivers and etc. Redownload all files, disable firewall and antivirus. But first you need to install fastboot and flash the u-boot for ice cream.
Inside the fastboot zip by lelus is more instructions on how to set it up. And checkout the original thread about fastbooting the l9
And you might want to try on another PC,
You need a good and clean windows environment for all to work well. This is the problem with many people. Plus a lot of antivirus programs don't like the small server.

well, if you boot into a screen that is neither android nor recovery, it should be fastboot at least this applies to my phone
since the combination is one button + plug in cable i guess it's the right one
does it say fastboot mode in the top of the screen?

Well I managed to get to fastboot with the p940 script. The screen that comes up with "S/W Upgrade Please wait while upgrading...". this may be some sort of fastboot derivative but there's no response to "fastboot devices" at the prompt. Can I flash cwm through fastboot if my bootloader is locked? I had it installed with the bootstrap method.

Hey don't flash ice cream and ect.
All you have to do is flash (in fastboot) the boot.IMG for the kdz you are on, and you're good to go.
Extract the boot.img from the kdz
Look at my guide. Or just wait until later tonight for me to upload it.
To tell you the truth, Lol, I did the same thing you did with the battery. I was fast enough to edit it before it shutoff. I had toolbox lite app installed.
CM 10.1 P769
Finally got it! :laugh: Turns out, the default path for small server is c:\shttps\www - the problem I gave myself is that when I didn't extract to the c root, I copied from my L9 directory - when I copied none of the contents of \www copied with it, once I moved those files to the correct position it all went through as it should!
Thanks for your help guys!!

hahaha I saw this about 10 mins after I got it to boot! lol - oh well, I'm running 20f now, getting ready to root and see about unlocking the bootloader. Now that the flash tool is working correctly, the only thing I have to do is get a feel for the mirrored, wonky screen. I've been researching the bootloader method but could never get that flash tool to work correctly. I'm in the game now! WOOT!

Just be sure you are ready for everything,
I recommended flashing 20d then 20b.
Hold up I'll give you all the help I gave to someone in a p.m.

I didn't have a hard time, but then again I've studied my a** off, and I knew how to fix all problems that popped up. My advice to you is read all the threads about unlocking the bootloader. The video is good but it doesn't break it down enough.
Let me tell you about everything that can go wrong and how to fix it
Problems
1. After flashing the euro kdz your phone won't boot past the logo.
Okay, this problem will make things harder(but do able), because you have to hard reset the device by pressing/holding the vol (-) + home + power (let go of power button when the lg logo comes up)
Plus after a hard reset all data will be wiped and you will have to enable USB debugging on the wonky touch screen.
The chance of this happening is rare because you are not coming from a custom ROM.
2. After flashing you get a security error (or an error during the flashing process).
Now this one sucks because you will need to fastboot and flash the ice cream u-boot. Then put the phone in the s/w upgrade mode and perform the offline flash again.
I had this happen to me once, while flashing the wind kdz. Messing with fastboot is not hard but it takes time to understand it. Get familiar with it first before trying to unlock. I'll send you a link with some more info.
3.After flashing the euro kdz you find out you don't have root.
Sometimes rooting fails (dam computers)
Now I had this happen to me after flashing euro kdz (so no cwm) but I wasn't really worried about that because I had a signal and I could make/receive calls. I had a signal because when I was flashing I swapped out the euro radio (p760.fls) with the metropcs one (lgms769.fls)
Note: you have to extract the radio from the metro kdz and rename it to p760.fls
When flashing replace the 11th bin (with hex edited 11th bin for 20b) & the radio (from metro renamed).
Another thing don't rush the unlock. I waited about 3 to 4 hours before trying, plus I took a couple of calls on the 20b kdz. And I was on wifi.
I flashed the euro kdz at work and when I got home I turned on WiFi and waited another hour.
I'm not to sure about what the video says about turning off and flashing the radio.
When the unlock first came out, the instructions were to not turn off the device before unlocking.
When I flashed the euro kdz I was on the metropcs ROM.
This is what I recommend and did.
Enable USB debugging, show all touches, & allow install from unknown sources.
Leave your phone on normally(don't put it in s/w mode) and flash the euro kdz and hopefully no problems.
After waiting a couple of hours try the unlock command with Adb on your PC.
If all goes good the phone will take you to an inverted unlock screen, just press the volume up (make sure you press the Up button!)
This will take you to the official fastboot (but it's inverted), now in fastboot flash the cwm recovery image.
In cwm flash the touch screen fix and restore a backup.
Another thing make your own backup with the locked bl cwm (just in case you have to erase all data) make backup on external SD. Another thing, Lol ,make sure the backup is good, try to restore it. I have had several corrupted backups with cwm.
I know it's a lot to learn, but then again you want to be prepared.
Think of it like a final exam, Lol and you won't go wrong.
If you get lost just holla at me.

So, I found a solution in XDA (/showthread.php?t=825173&page=3) saying that I should plug my phone in without battery, SD nor chip and disable the "LG Modem" on my Device Manager. Afterwards, start KDZ Updater and configure it to CS_EMERGENCY. Then I should install a 2.1 French firmware and as soon as KDZ finishes I'd plug off my phone, plug it back in and start it in DL mode again, this time flashing a file named "OUT.kdz", which gives back the boot logos.
Problem: KDZ Updater hangs as soon as I press "Start". It simply freezes when it's in CS_EMERGENCY. I have no solution to this whatsoever, and I also have another thread with previous problems I ran into (Soft-Bricked LG GT540 Optimus).
These are the best forums I've found for any kind of phone, so I'm positive I'll get the help I need, even if I might need to wait some time. Kudos to the admins and every member for taking part of such a great community!

Okay guys, I think my phone has a soft brick (no boot logos), so I'm trying to do some restoration... but I'm not having much success.

I've fixed all my issues! I'll paste what I said in another thread. Yay for one-full-year struggles!
Just wanted to leave my 2 cents here, I've been trying to do my best since around august 2014, no success. 2 days ago I retried this, and I DID IT! I will tell everyone what I did very shortly:
My problem that I solved: I can boot, device works like a charm. But: no boot logos, no recovery.
My solution for TL;DR: UNINSTALL ALL DRIVERS FROM DEVICE MANAGER 1ST, then reinstall. After that, flash a fastboot ROM and use it to WIPE ALL THE DATA IN YOUR PHONE! THIS was what I needed and was never explained: you had to WIPE the old data in order to get the boot screens back.
IN THIS ORDER (THANK YOU to those people from previous replies, gathering all your info was of great value):
Uninstall all of your phone drivers from your PC!!! This is what made most of my headaches go away, just use Device Manager and uninstall anything from LGE. After that, plug in your device in your USB ports (always BACK ports, not front ports, important). It should detect all drivers and download them.
IF it fails (it generally does with LGE USB Modem), you can go to Device Manager > Unknown Device (the one that wasn't recognized) > Right Click and Update > Choose 2nd option, then choose "choose from a list of local controllers" (or whatever the button says). After that, scroll down to LG Electronics, Inc. and install what didn't install.
I also found these drivers, but I did not test them: http://www.mediafire.com/download/p693hcz6kkouh19/USB_Driver_LG_GT540.zip
Huzzah!
Now you're set to begin:
FIRST thing you wanna do is a factory reset, this is something I'd forgotten with time, don't make the same mistake as I did. You can do it by turning your phone on and pressing Volume +/- & Home & Quick Search buttons all together for 5 seconds (it works, be patient and wait for it, even if you open the camera or any other stuff).
Download this Google SDK Tools (unzip and put the folder in C:\ drive) and this Fastboot drivers for GT540 (unzip and put the files inside the folder in C:\android-sdk).
Skip this next line if you know your ROM has fastboot.
Now, if you don't have a ROM with fastboot, I recommend you use either European Open+Fastboot or V20C Orange France Fastboot ROM.
Click to expand...
Click to collapse
Since you have Fastboot enabled, now all you need to do is turn off your device (all this with its battery on it, no weird things) and hold the Camera button before turning it back on. This should take you either to a black screen, or simply to no display, like me. Either one will work anyways.
Now press the Windows key > Type cmd and open it with Right Click > Run as Administrator.
In it, type all this, command by command (you can paste by right clicking):
cd C:\android-sdk
fastboot -w
fastboot erase boot
fastboot erase system
fastboot -w
fastboot reboot
Click to expand...
Click to collapse
And now it's go time! Do what everyone else says in here: Take out your phone's battery, SD and SIM cards, fire KDZ Updater up as Administrator (If your KDZ freezes, then it's either faulty or you did not install msxml, look for a good KDZ that comes with that file and delete your current one), choose CS_Emergency PhoneMode and:
1-Plug your phone while holding the volume DOWN button (don't worry! My phone didn't show "Download Mode" either, if you hear the Windows "Somethingpluggedin" Bump noise, it's ok).
2-Flash French V20A
3-Unplug your phone once KDZ says "==FINISHED==".
4-Plug it once again, holding the volume DOWN button.
5-Flash out.kdz (remember! it's CS_Emergency).

THANK YOU XDA!
Recently while flashing alpha version of MIUI marshmallow on my Mi 4w, my phone got completely bricked. Complete brick in the sense, it won't turn on, neither charge nor show any led indication. This guide should work on other phones also.Let's start:-
1) Although it seems like your phone wont turn on, your phone is actually working, it's just it wont show anything on the screen(no display).
Make sure your phone is charged properly(it will charge even if the led doesn't show any indication).
2) Download and install Mi flash tool and then Fastboot file of your device. http://en.miui.com/a-234.html
3) Unzip the fastboot image, a folder containing flash all.bat should appear if not, extract the extracted file again. Winrar should work fine.
4) Now open Mi flash tool(as administrator) and select the fastboot folder from Mi flash using browse option and also select the proper fastboot script according to need.
Note: Flash_all.bat will completely erase your internal storage.
5) Now press volume down(-) and power key to enter into fastboot. Note: it won't show any visual whatsoever but it'll work.
6) Connect your phone to your pc. It should show various flash devices connected to your computer and those devices may continuosly connect and disconnect. If not it'll show QHUSUB_BULK install the driver using device manager.
7) On Mi flash tool, some device name should show on the devices list if not click refresh and try reconnecting the device. Note: If you dont have proper drivers installed on your pc, this procedure won't work.
8) Finally click on flash and flashing will start. It'll take some time. Once done it'll show operation completed successfully.
9) Finally boot your device using power key.
Brick has received QHSUSB_BULK simple. This is the normal and regular encounter. Hardbrick, you must check point.

How do I put the phone into fastboot mode if it is hard bricked? It won't turn on, I get no responce from phone. When I use method connecting test point to metal cover on mother board of phone usb connects to PC and MiFlash recognizes phone. Try to flash though and I get an error message. No matter what ROM I use, zipped, unzipped or tgz file. Can my phone be unbricked? What am I doing wrong? I have a Mi Max 64GB and am using HELIUM Roms. Please help. Error message is:
The filename, directory name, or volume label is incorrect.(0x8007007b: Open programmer "MPRG*.hex").
I have no clue. Not my first time flashing ROMs or unbricking a phone. It is my first time on a Xiaomi. Only done blackberry and samsung before.

Link not working.
Using another mi flash tool also get nothing. How do I know I get into fastboot?
Already pressed volume down and power button but nothing happened. And checking fastboot devices nothing comes up. Also in mi flash tool nothing.
WARNING, THIS GUIDE WILL WIPE ALL THE DATA IN YOUR DEVICE.
!!! Whatever you do, it is at your own risk !!!
This procedure will unbrick any Axon 7, returning it to stock. It fixes any kind of brick as long as your hardware is not damaged. You can't damage your hardware using software so if you have a healthy unit, you can recover it from any flashing "accident".
1. GET THE SOFTWARE
You need a Windows PC, Windows 10 is highly recommended. Do this:
01. Install MiFlash in your PC. It includes the Qualcomm Snapdragon SoC drivers, nonetheless you can always install the latest drivers.
02. Download the EDL flashable stock firmware package for your model:
A2017 (China): B14_MIFAVOR5 Android: 7.1.1
A2017G (Europe): B10_NOUGAT Android: 7.1.1
A2017U (Americas): B35_NOUGAT Android: 7.1.1
03. Unzip the firmware ZIP file to a folder in your hard drive.
2. ENTER EDL MODE
Option A: USING THE REBOOT COMMAND
If you still have access to your system but not to recovery or fastboot, then you just need to install any terminal app, open it and at the app's command prompt enter:
Code:
reboot edl
. You device will reboot into EDL mode. Now you can safely plug your Device to your computer. In your computer right click in the Windows Start Menu icon and select Device Manager. Under Ports (COM & LPT) your device should appear as Qualcomm HS-USB QDLoader 9008 using a virtual COM port. If you can see it, then you can continue to the flash section, step 14. Otherwise, if you do not see anything or a DFU device, then you'll need to explore the next option.
Option B: USING THE BUTTON COMBO
04. Press the VolUp and VolDn buttons in your device and keep them pressed.
05. Now press the power button until the red LED flashes, it does it really quick. Then release the buttons, starting by the power button.
06. Plug the device to your computer.
In your computer right click in the Windows Start Menu icon and select Device Manager. Under Ports (COM & LPT) your device should appear as Qualcomm HS-USB QDLoader 9008 using a virtual COM port. If you can see it, then you can continue to the flash section, step 14. Otherwise, if you do not see anything or a DFU device, then you need an EDL cable.
OPTION C: USING THE EDL CABLE
So, you need to get a Qualcomm EDL cable. With it you can recover from any situation. I use this one, DrakenFX uses this other model. There are cables out there not working properly so do not try to save 4 or 5 bucks and get yours from a reliable source. Alternatively you can solder your own by following this guide. If you are in an emergency (or your patience threshold is very low) and have a thin wire around you, then you can follow this DIY hack video.
Do you already have the EDL cable? then follow these steps:
07. Connect your bricked Axon 7 to your PC using the EDL cable.
08. Press the EDL cable button and keep it pressed.
09. Press the Power button of your bricked unit and keep it pressed too.
10. Wait 20 seconds.
11. Release the power button.
12. Wait 10 seconds.
13. Release the button of the EDL cable.
Voilà, your device is now in EDL mode. The device manager in your PC, under the ports category, should detect it as Qualcomm HS-USB QDLoader 9008. Now you can proceed to the flash section. If this procedure doesn't work, then your unit could have a hardware problem. Your only hope is to dissemble it by following this last resort guide.
3. FLASH FIRMWARE
14. Open MiFlash in your computer.
15. Click Browse button and select the folder you created in step 03 with the stock firmware files.
16. Click Refresh button and your device will appear listed as virtual COM port.
17. Click Flash button and wait for a few minutes until it finishes. Note that the bottom options are not applicable.
18. Now you have a stock Axon 7. Your data partition will still have garbage data, so you should enter recovery by pressing VolUp while rebooting your device with the power button. Release VolUp only when you reach Recovery. Using Recovery do a Factory Reset of your device.
That was the last step. Hopefully now you have a fully functional stock Axon 7.
By the way, this guide can also be used to return to stock any working device for selling or service!!!!
Cheers!!!!
Nice! I just disassembled mine and did it that way the other day.
thank you.
i will save the files and guide for rainy day.
i have A2017 that i converted into A2017U; which file do i need to download?

I don't know what you mean about converting an A2017 into an A2017U. They are the same device except for the radio, that that's a hardware difference. You should always use the right modem firmware for your radio hardware so you should use the A2017 modem firmware. After unbricking your unit, you can unlock it again and flash any universal firmware the same way you did before. It is a long but safe process.
yes, i meant to say that i flashed U radio over my A2017
so China version is for me.

If you flashed the A2017U radio in a A2017 hardware and worked fine for you, then you can use the A2017U B35 stock firmware.
What will be the bootloader status after following this guide? I need my phone with a locked bootloader.

It should be locked. But in case you end up with an unlocked phone, then locking it is very easy. You only need to connect your phone, enter into fastboot mode, download the adb/fastboot tools and execute the command fastboot oem lock from your computer.

I can't get into EDL mode. I hold down volume buttons, then power. When the red led lights up, I unpress power, then the volume buttons, connect the USB cable and nothing happens on my phone (black display) red led still on. On my computer I see ZTE Handset Diagnostic Interface(DFU) (COM3).
Edit: I managed to get into EDL mode thanks to Axon 7 EDL Tool but I got a "File analysis: error" "not important files found" so I went back to MiFlash and also got an error about the files. Will update the post when I get it to work.

xD My phone was bricked. I thought this tutorial was mainly targeted for bricked devices.
Anyway, my phone is working now. The downloaded EDL zip was corrupt so it only had a few files inside.
@Oki
Edit: I have a working phone on Nougat B10. But I can't lock the bootloader because I don't have access to fastboot. My phone's variant is A2017G

Glad to see you solved your issue. I misunderstood your problem. I thought you had access to the system and not to recovery or fastboot. Anyway, this guide is for unbrick or return to stock. I'll investigate the relock problem. Usually clearing devinfo partition should be enough to relock any bootloader.

In order to get access to fastboot I had to use the tool Axon7Toolkit, select "unlock bootloader" option, make sure you have an old version of MiFlash installed (20161212) and then you can select "lock bootloader" on Axon7Toolkit.
Thanks for everything.

Well, I am considering to link the older Marshmallow ROMs since the Nougat ROMs have some issues with fastboot. Anyway. It is going to take some time to test the alternatives. Thanks for letting us know!
Some of the most recent firmware for Axon 7 (@NFound's B12 bootstack, I think) doesn't support the EDL button combo. But if you have TWRP installed, you can boot to recovery, then reboot to EDL from there.
I kept getting the device registering in device manager in DFU mode. But I noticed that it briefly registers as QUSB_BULK before reverting to DFU. So I installed zadig winUSB driver and now it registers as QUSB_BULK when I turn on the device pressing all 3 buttons.
How can I proceed now?
Hi there
Thanks for this guide. I have a 2017U, so I got A2017U_B35_NOUGAT_FULL_EDL.zip file. After unzipping and connecting the phone to the computer it gets properly recognized and i can start the process from the MiFlash program. After reaching somewhere between 30-40% of the flashing process, it goes suddenly to 100% and it says that is finished. When I reboot the phone, it appears as if I was still under an unlocked bootloader (warning message + TUX penguin image) and the phone starts but during the initial setup process, i chose to start as a new phone but it says that "This device was reset. To continue, sign in with a Google Account that was previously synced on this device" and obviously this is not what I am interested for.
How can I get rid of this message and get a full clean install, with bootloader relocked and all that??
Thank you for any help you can provide!

There ate several ways to remove that. One involves TWRP 3.2.1-7 and the other Axon 7 EDL tool, if you dont have TWRP then use the second . Jusy go to the unlock menu and apply the google unlock.
A third way would be to setup the phone with your old google account and do afactory reset from within Android, not from the bootloader. That would remove also the owner safety.
Thank you so much for your guide and software bundle.
I even had to make a EDL cable to restore my device.
After flashing, I do not see vendor as a partition but looks like it is a folder. Is it OK for future ROMs ?
