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.
Here is the log from KDZ:

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

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!

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.

As far as I know, the extracted dz renders bin files for partitions. So how did u flash them using qfil/qpst? Doesn't qfil require mbn and XML files instead?
After being stuck in qloader 9008 mode, I decided to flash the kdz to a micro sd card using eMMC software download as I saw other people do it with their phones and it working fine. However, when I put the sd card into the phone, the screen was still black but this time instead of qloader 9008, it detected as AndrodNet USB Serial Port. When that came up, I thought I could use LGUP but there's a problem with every LG tool I used.
LGUP Would Show unknown model and show a com port number and nothing after it. When I did select that port it would say "you have to select a known model please"
When I used LG FlashTool 1.8.1, every time I would load a firmware and press the yellow arrow, It would say "Failed PreviousLoad()". (I know this software works because I have tried it on different phones and it would work)
When I use LG Bridge, I'd select update error recovery and it would go on "checking device information" and would return back with "connect your mobile device to the USB port. If it is already connected, contact LG customer service.
When I use LG Flash Tool 2014, It would say "problem with communication between cell phone and PC"
Does anybody have any other ideas or tools for me to try? All help I can get is appreciated. Or was it better to be stuck in qloader9008 mode?
My smartphone LG V20 h910
after installed LineageOS android 9
everything was fine, but then I wanted to return the stock Nugat 7.0 back, but in the end now my phone is hanging on the LG splash screen.
Now I don’t know what to do, the computer sees the phone as a COM port, LGUP does not recognize (unknown device).
the uppercut also does not recognize
LG Flash Tool (Commode Fail)
Is it possible that the problem is with the USB Type C?
