Hello,
I have a LG P715, and it is stuck on security error. When i try to switch it on, it displays lg logo for 10 seconds and then the screen flips and i see security error with lg logo.
I tried googling it, i found out i have to use lg mobile support tool. To use it, I need to put my phone in emergency mode, which i cannot do.. All tutorials say to plug in usb while pressing Vol - key, which when i do, leads me to a screen with a blue battery icon with a lightning bolt icon in it.
Any help will be appreciated.

Hello Azim! Are still having troubles with your LG P715? Well! I have done the following:
1 - Downloaded a CIS V10j rom to this model P715
2 - I copied/pasted the 3 adb drivers (Adb, AdbWinApi.dll and AdbWinUsbApi) that I found on Android Multi Tools V1.02b folder (found to download) to the folder C:windows/system32 (My o.s. is Windows 7 x86. if yours is windows 7 x64, you must copy/paste them to C:windows/sysWOW too).
3 - Opened the LG mobile support tool and I chose to install the drivers to the LG P716
4 - Renamed the fold C:LGP716 to LGp715
5 - I ran the "windows enabler" (KDZ FOLDER) as admin and then, I switched it on at the "TRAY" close to the clock. Maybe this has not made any diference. I just have done it. you'll find it searching for kdz update with windows enabler.
6 - Then, I plugged the phone to the pc (while LG mobile support tool was still open) through usb holding vol- and it worked. (LGE AndroidNet Usb Serial Port s been recognized)
7 - So, I closed the LG mobile support tool and I ran the KDZ as Administrador and in compatibility mode to Windows xp sp3 ( right click on kdz icon and check the boxes due to these options at the window COMPATIBILITY).Good luck ! Sorry for my bad English. hug

Almost forgot that the mobile got stuck at LG start windows and I performed a reset and it worked
Flash this boot.img on boot partition first via TWRP 3, then flash any rom (stock rom recommended first).^
[If you don't have recovery then flash modded kdz by maxx_hr.]
OR
Check that it is boot.img and not boot.img.zip or boot.zip.
What rom are you going to use?
Tel me if this helps and click the thanks button.
But to FLASH, he will need to set it on Emergency or Download mode first. Maybe this will fix his trouble it the future, if he ll needs to make the procedure again. ^_^

Maybe he hard bricked his Phone in the past? If he can use adb, then he can restore the emergency partition so he can access emergency mode.

I flashed custom recovery image successfully and after that, when phone has to restart, it just stuck at LG logo.
When I tried to enter in custom recovery menu, but it shows only LG logo.
I tried to connect with PC, but it was unsuccessfully. The PC doesn't recognize the device. (nothing happens).
Can anyone help me?
This happened to me also. I solved it like this:
First thing to do is get sure the LG drivers are installed ( there is a topic in the forum on this also).
Install KDZ ( serch in the forum and download it)
Download a room ( stock or not )
Flash the phone with KDZ ( after the drivers have been installed the phone should be detected on the pc.
After flashing if it does not start up do not fear, get the battery out, re install the battery and do a hard reset power+home+volume down buttons pressed at the same time and it should work.
If its your first time install Stock GB 20E as it is an open room, if not new to this I would suggest CM7.
Hope it helped
Regards
But the PC doesn't recognize the phone.

I had this same issue too, do not worry.
Keep your phone plugged into your computer, and go to Start > Control Panel > System > Hardware > Device Manager > Modems and disable the LG modem.
I am on Windows XP, so it may not be the same steps, but the point is that you have to disable the LG modem in Device Manager.
I had the same problem as well at one point. What operating system are you running on your computer?
I had the same issue, but I could not find the LG modem to disable it, it was just that windows was not detecting my phone at all, or using the drivers I had installed for my P500 to figure out what was connected to my laptop. Bricked phone after a failed ROM flash. Reinstallation of USB drivers for my phone failed to do anything.
Have you used LG Mobile update at all? I got all my drivers through it, rather than useless PC Suite 4.
Download it through HERE
Here's what I did to rectify it (Running windows vista):
DO NOT PLUG IN YOUR PHONE UNTIL STEP 3!
1. Went to system restore in windows(you'll find it under Backup and Restore in the Control Panel) and restore your computer to a state before installing any drivers for your phone.
2. After everything had completed, installed LG Mobile update. There is an option to install general USB drivers for your phone, DO NOT do it! Go to Customer Support > Application, Manual & USB driver download. Input your IMEI number from behind the battery in the back of your phone(or just select the "Read your phone" option if you can get it to read your phone). It will search and return the correct drivers for your exact phone. Download and install your USB drivers.
3. Keep your phone disconnected from your PC, and start up LG mobile update again. Connect your phone, LG mobile update should verify the connection by trying to connect to your phone, checking software versions, etc. It will connect even if you are stuck at the LG screen.
4. If everything checks out run KDZ updater and flash your phone back to original specs.
hey first go to emergency mode by pressing back(return) and volume up
and then in emergency mode use kdz it then only pc will recongnise your phone
believe me this thing also happens with me and I know that time I very scared
that time I used this article

read general thread it has been answered many times,stucking at lg logo is solved by take out battery reinsert and the 3 button combo
have u tried HOME + VOL DOWN +POWER BUTTON,still if it dont,
read downgrading details here http://forum.xda-developers.com/showthread.php?t=1038338
error guide here http://forum.xda-developers.com/showthread.php?t=883314
The same problem. But i solved it.
1) install again the driver using B2CAppSetup
2)This is based by xda forum by: Zecanills with a detailed explanation from my side.
- You need to download the firmware of your device. Download "Orginal LG Firmware" application (search in xda forum). Open it, put your IMEI and you will download the original ROM.
- Download KDZ updater and uncompress it
KDZ_FW_UPD_EN.zip - 4shared.com - online file sharing and storage - download
- Install msxml.msi from the uncompressed directory
3) Remove the battery, put it back and start the phone in emergency mode (actually the only way possible) back+up volume+power
Connect your device and run KDZ_FW_UPD.exe (as administrator). If the phone is not recognized repeat step 3) several times.
Select Type : 3GQCT
Select PhoneMode : DIAG
In KDZ file : Choose the ROM file you downloaded in the step 2)
Press Launch software update and wait (It will be 10 minutes or so).
Wait until it reboots.
After reboot will appear an image as in the following link: http://androidforums.com/getitnowmarketing/330813-all-one-recovery-thread.html
Don't worry. Restart phone again pushing power button (or remove battery, put it back and push power ) and then after few minutes you will have the phone as the begging when you bought it.
Thanks people for helping me. I just put the phone in emergency mode (Volume UP button + Home button), connected to the PC and flashed with KDZ.
After that, the phone works fine.
Thank you again!

No responses to Emergency mode flashing by KDZ?
Try at least with HARD RESET... Hold Power Key + Volumen Down key + Home key
When LG logo appears, release all the keys! Good luck!

First, there is no such thing as hardbrick (not anymore, most modern phones cant be hardbriked )

[Q] How to install a .kdz?
[A] (Tutorial thanks to @[W]ar[H]ead, confirmed working by TaZRAge)
#1) First to get into download mode:
1. Remove battery
2. Put usb to computer and phone (w/o battery)
3. Hold "Vol up" button
4. Put battery back
You will get into download mode (aka emergency mode).
#2) Unpack kdz flasher, and install msxml.msi.
#3) Run KDZ_FW_UPD.exe set "type" to 3GQCT and "phonemode" to DIAG.
#4) Choose the .kdz file to flash. Download link is under the "Downloads"
#5) Click "Launch software update" and wait. Phone must be connected in download mode(!). KDZ installer might get stuck but DO NOT disconnect it. (Unless it stays that way for a hour as a example)
NOTE: .kdz is a .kdz, you cannot extract it. If you get a .zip from the LG .kdz site you did something wrong.

You don't know what you are saying. You can HARDBRICK ANY modern device. By definition hardbrick means phone won't turn on won't respond and in some cases recognized as usb when connected to pc as usb bulk or qcom usb. etc. You damage the second bootloader and tell me what happens. You will see what you get.

first this is offtopic. Second, u are wrong ! Unless the phone is pshisicaly damaged (misfuctioning components or damaged), u cant hardbrick the phone with uploading different soft. on it (unless u change voltages and overclok, if that is possible on the device). Ofecourse they are exceptions, but all major modern manufactors, make hardbrick proof devices. Also, how exactly would u modify the emergency mode, and more important even if you could, why wold u do it !?
More on to the topic, none of the operations of rooting, bootloader installing, kdz install or CMx install , gets near the emergency mode. It remains intact.
Just retry all normal steps for installing kdz or recovery again, check the cables, all drivers on pc, and is best to have a charged phone battery.

I am not gonna reply again but I am just saying you have no idea. Do not talk unless you are sure you can hardbrick any device with just root and just writing on second bootloader partition. Read about it if you don't know. Do not argue about it.

No, no luck yet. Seems to be impossible.
I connect to this post cuz my d605 is also facing a similiar issue, no system, no recovery, no adb, download mode worked only twice, for the rest, only emergency mode works, phone cannot even charge.
Phone is recognized from pc, I uninstalled modem drivers but stays in Emergency only few seconds then it shuts down (not sure if its the battery, since it doesn't charge as well). It shuts down actually at the moment that LG mobile support tool seems to recognize it.
It worked couple of times, phone was keeping staying in emergency mode for the beginning of the procedure but at the moment it need to put the kdz into the phone, the phone die.
The two times download mode worked, same, just shutting down immediately. This with LG support tool or LG flashtool2014.
KDZ_FW_UPD worked the first time after install and then doesn't run anymore, on two different Win10 machines.
I have no idea how to come out of this nightmare, just want to flash it :/

well, sorry for not replying earlier. My phone was on guarantee for about 2 months after I wrote the post. I just send it to LG Hellas via the e-shop I bought it from and in about 2-3 weeks, I had my D605 back like it was brand new. I searched a lot about my D605 hard bricked and I found that it is not fixable. My phone could not go into download mode though, as yours. Hope I helped you even a lil bit. Sorry for my bad English.

(For you guys,there seems to be no options as of now.You will have to replace motherboard or wait for JTAG support.IF any of you need me to try to find a method you are welcome to sent your device to me so i can check it out.) ]
This can occur when flashing wrong images to the partitions when in qhsusb mode.
IF YOU CAN ENTER QHSUSB MODE [BLACK SCREEN BOOT] THEN FOLLOW THIS TUTORIAL

Just FYI - this is an incorrect statement. I myself had a QHUSB 9008 error and it was fixed REMOTELY (using TeamViewer) using a special software called BoardDiag by some members on this board (like Tungkick). It does cost 20-30$ though, but the G2 is one of the most repairable phones I have seen

I had the same problem with my L4 II I had to open LG flash tool like 7 times
Program may crash
It can stop on process
Window can freeze
It can disconnect
Just keep trying it
I read some tutorials and they give some tips:
Here is what i did:
I used windows 7 x64
First thing is to run flash tools as admin
Second is to place your .kdz on the same folder where you have LG flash tool
Third one is to close all your programs and leave only the Flash tool open
Pick your .kdz file and select cdma and diag
Now turn vol + and vol - and connect USB (Screen turns on with logo and says ( ->Download Mode )
Now click on Normal flash, i think CSE erases all your data
Now Read Phone Information window appears just click START
I leave republic of korea and korean on the Country & Lenguaje window; it goes to english automatically
Click OK and LG mobile Support Tool gonna start
leave it there and the second or third step is going to stop and it will say something like reconnect your device
Ignore that and the bar will continue just let the magic happen
It gonna go to the fourth step and your phone is going to reboot and show lockscreen
Then you can close the tools and unplug your usb.
If bar stops and doesn't seem to have any activity then close window and repeat
Remember that with this method you can loose your root access
Hope it works for you friend, and sorry for my english too.
Hay guys,
I got a big problem, yesterday I tryed to downgrade my brothers LG P760 and made a big misstake.
When I tryed to go into 'recovery mode', I just used the wrong keys (VOL DOWN + HOME + POWER ON/OFF). Now my phone doesn't boot up anymore, it just hangs at the LG bootlogo. I can go into 'S/W Mode' and into 'Fastboot Mode', but if I go into 'Fastboot Mode' my decive driver is hangs in a loop. Hanging all day and night to fix this problem, but I can't do anything.... I hope anyone can help me!
Windows OS: Windows 10
Phone: LG P760

Yea, this is the last tool I used and it went fast as nothing else yet, but while flashing the stock firmware it doesn't continue at 60% and saying "Verifying phone connection...".
And does it work with Windows 10?
Thanks for your help!
Fastboot & L9 & Win10 ain't good for me, too.
But D/L mode is more basic and thus more reliable. And there are basically two ways to unbrick, online with the official LG tool, and with LG Flash Tool 2014 and a KDZ image. Only the first option works without problems for me.

Thanks for your time and answere!
Yea, I also think it's the Windows 10 which makes problems, I can't get any driver installed for this P760.
So I can just download the official lg support tool and try it this way?
EDIT: And btw... I did exactly the second step already and had also problems. I didn't did the D/L mode step yet. Can you explain how it works, I don't know how to come into D/L mode.
Thanks!
In da other Thread! In D/L mode the phone should get recognized by LG driver and a virtual com port be installed. LG software only works with LG drivers, and they sometimes don't recognize the phone, except in D/L mode.
Fir other purposes the Google SDK usb drivers are best, but then there's the Fastboot issue. But ADB should work.

The 'LG Mobile Support Tool' says that the right firmeware is already installed and then he is starting to download V20O with 599,15MByte. But the thing is, that the phone will just go out of the S/W mode while the 'LG Mobile Support Tool' is downloading the V20O. After the phone switched off, my driver is looping and always saying it can't recnogrize it. It does it like 20 times and then the phone will go on and LG logo appears. Nothing more.... :/
My P760 never quit D/L mode before or during download. Afterwards LGs recovery may appear, which calls itself something like Service Mode. This is not good, though the stock rom should initially work, but there are problems when rooting etc. In such a case leave phone connected and flash a second time. The phone should reboot to the launcher, if successful.
