Referring to this thread https://forum.xda-developers.com/lg-g2/general/mega-tut-how-to-fix-bricked-lg-g2-t3055033
I have found a shorter method of unbricking your LG G2 after troubleshooting uppermentioned method for quite some time with no result.
Your phone is stuck at boot in Dload>Download-Mode>Fastboot, mine is LG G2 D802
Your phone will not do Hard Reset when entering recovery and selecting Yes
Windows 10:
- First Install LG G2 Driver. v4.x works fine, I tried many and didn't have any problems in that regard, drivers all work fine
- Download LG Flash Tool 2014, not the fancy new one, but this old version
- Find the most accurate backup .KDZ file of your phone's OS, mine is EU16GB, and the file that worked for me was D80230d_00.kdz. Flashing the wrong rom will result in bootlooping that can be fixed by restarting the process.
1) USB connect your LG G2 in Dload/Fastboot to your PC
2) Run LG Flash Tool 2014 with DEFAULT SETTINGS, press select KDZ file, find the KDZ OEM ROM you found online that matches your phone perfectly, select Normal Flash and click Start
3) Your phone reboots into Firmware Update
Firmware update is the flashing process happening
If it fails you can try again by restarting your phone, or try another KDZ ROM
4) Once the flashing is done the phone restarts itself and boots into the OEM OS
5*) if unsuccessful try a different .kdz, personally I had to try three of them ,_,
i pulled these steps from my memory, i try updating if something is wrong
If I may ask, what do you mean with "1) USB connect your LG G2 in Dload/Fastboot to your PC"?
Could yoiu please elaborate what "in Dload/Fastboot to your PC" means?

I recently rooted & flashed custom rom (CM 9) on my Optimus L3.Then i wanted to flash it back to stock after i got bored of the ICS rom, and followed a KDZ Updater guide, and now my device is bricked. If i try to turn it on, it will boot loop forever.The KDZ proccess was perfect, i had no errors (atleast i think i dont).I really need help to save my phone.
Used Windows7, had LG PC Suite IV Installed, i disabled LG Modem, I was in Emergency mode, .kdz used *V10H_00*.

I also tried LGMDP, but it doesn't recognize my phone, since i somehow can't manage to install the drivers correctly since it can't boot..
Hello guys.
I've been trying to do this on my LG Optimus L5 II E451g and it doesn't work. I can do the NORMAL FLASH but it didn't fix my problem so I want to do the CSE FLASH (to do a clean install). But I can't do that one.
Everything goes fine until the third step: "Wait until software extraction is complete..." then after a few seconds it crashes "LGUserCSTool LG Mobile has stopped working".
I'm using Windows 7 Ultimate SP1.
I tried different drivers, the old method with the host file automated (says the phone is not connected but it is), LG Update Tool 2014 and KDZ Update but nothing works. This error says the module with trouble is "msvcr100.dll". KDZ file is in the software folder, Windows recognizes the phone when I conect it to enter Download Mode, I installed every Visual C++ package I found, everything seems fine but it doesn't perform the CSE FLASH. It does the NORMAL FLASH so the KDZ is fine.
I'm sick of this. I don't want to buy a new phone. Anybody has any idea???
Regards.
I have EXACTLY the same problem here.
And I can't flash KDZ to at least recover the phone. System got corrupted, so it doesn't boot. Recover doesn't work (just shows the open robot with the exclamation sign). Download Mode works but the tool throws this error.
I have a previously 'security error' P765 phone. Recently,there seem to be easy ways to get rid of that. So,I tried.
I tried this:
[GUIDE] [UNBRICK][ROOT] FLASH Any LG L9 Factory ROM (kdz) WITH OFFLINE FIX
(http://forum.xda-developers.com/showthread.php?t=2085344)
When the phone is flashed and rebooted, I find that the animation was loading too long, so I rebooted the Phone.
I think here is my fault,as I later researching in the forum said I should wait at least 30 min.
I tried the above method again.
It can't detect my phone, isConnectedPhone is 0
So I tried other flashing method,like
P765 Unbrick Using LG Flash Tool 2014(http://forum.xda-developers.com/optimus-l9/general/p765-unbrick-using-lg-flash-tool-2014-t2950433)
It stuck at 50 %
Am I out of luck? Or is fastboot my last method?
Thanks in advance.

try this
1) change usb port
2) change cable
3) Use another pc to flash ( Win7 OS preferred)

Hi, everybody.
Do you think it makes sense to flash some recovery (Eg. cwm) by some means(fastboot?) so that I can flash some rom to my P765?
Unfortunately my boot locker is still locked.
Thanks.
I was running a MarshMallow update for the last 6 months and suddenly today morning I just decided to flash the "rootedsystemh960a.tot" from one of the forums here at XDA. First it did flashed the ROM using LGUP but then the Phone was stuck with LG LOGO for minutes and then I flashed it again with my stock UAE MM 6.0 ROM. It did work. Then I reflashed again hoping for the ROOTED ROM to work on my phone and ever since LGUP is giving me this error code with a message " lgup error code 0x2000 invalid command response" and it keeps crashing. Now I have tried to switch windows and tried to flash many ROMs and it wont stand a chance. Why this error message is coming? Can anyone of you experts figure this out? Even the COM ports are matching at LGUP and in my DEVICE MANAGER. Please help me. I am stuck with this mobile. ...:crying:
Little info about my phone. It is a UAE/DUBAI Variant of LG V10 - H960A, and officially I am not allowed to unlock my BOOTLOADER by the LGE itself. I had tried before bootloader unlock modes.. Anyways its not the point here right now.. The main thing is LGUP is crashing again and again.. Is there any other utility in place of LGUP for flashing LG ROMS ????
Well that .tot file was for Lollipop only that was your mistake in this probably and it has corrupted your system somehow. I'm afraid I have no idea how to deal with this phone as I don't modify this one myself because of the lack of development/devs.
I think there is something called LGFlashTool also.

Hi,
can you enter the download mode on your V10? Then it might be possible to flash a clean (unrooted) MM via LG Bridge. Some time ago I tried to install the latest MM Version V20e on my V10 with LGUP. For some reason that failed and left me with a phone without ROM, too. Afterwards the V10 was not recognized by LGUP anymore.
Luckily I was still able to enter the download mode manually. So I connected the phone to my PC and started LG Bridge which still did recognize it as a V10 H960a. So selecting Firmware update and then clicking in the bottom right corner of the window on a link saying something like "repair flash errors" or "repair update errors" (I'm currently at work and cannot check) did a complete clean install of the latest firmware.
Maybe you're lucky and this works for you too.

Well hello, I found the solution for my problem and I was able to flash the ROM successfully. Its some kind of new utility amalagamated with LGUP and it does flash without any problems. Found out it was related to some corrupt dll file or incompatible file I had in my LGUP library for the ROM FLASHING to fail all the time... You just read this first post on this link and you will be all fine. Trust me ...:highfive::good::fingers-crossed::fingers-crossed:
https://forum.xda-developers.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295
Just dont forget to follow the rules exactly as mentioned and if you can run it in the Virtual Machine I would prefer you to do that but you have to do everything like installing LG DRIVERS + LGUP + LGUP DLL FILE + UPPERCUT as mentioned in this post. Because if you are running antivirus on your PC, it will detect this UPPERCUT TOOL as some trojan horse or some kind of malware. I did that in my VM as I already had my VM configured for my LG V10 Flashing process.
Do it and do let me know should you encounter any problem. May be I can help later on.
I have all day trying to solve this problem, I did an update for the Verizon application and now I am in the download mode, I want to recover it using LGUP but it says that the model is unknown, I used uppercut, installed the different .exe of the dll , and nothing.
I'm about to EXPLODE
AND THE FLASH TOOL LEFT IN PRIMARY GPT AND THEN AN ERROR

uhm, never used LGUP even if I have G2 and G Pad 7 (always used LG Flash Tool but it seems is for international version only), but anyway: guess you installed the right drivers and check if there are errors in Device manager (the exclamation mark in the driver icon)? Usually when LG devices are not recognized by the flashing tools the issue is with drivers, so trying on a different PC may help (you can't imagine how many times worked for my LGs!!).
Also the LG PC Suite (don't know if it's available for you) has an option to restore a bad update (firmware update) and - like LG Flash Tool 2014, too - you have the option to insert the IMEI before attaching the device to the PC, that way you somehow force the tool to select the right firmware to flash, does LG UP has something similar?

Yes, I have the universal drivers, I have tried it on another computer, I will try lg pc suite to see, lg flash tool only works with a single KDZ but it does not install, if I try to put the latest version it says it is not compatible: S

there are different LG Flash Tool tools.. One is LG Flash Tool 2014, requires kdz; one is LG Flash Tool 2.xxx and it requires tot firmware files; and then there's the original LG Flash Tool (used by PC Suite too) and it's the only one that let you enter the IMEI and it dynamically download the original firmware from LG servers.. but this is for my LG devices, G2 and G Pad 7, don't know if they're all good for your VS500..

When I try to use it, the LG flash tool got stuck on PRIMARY GPT 00000, and when I used Verizon S / W it got stuck at 3%.
The page can not provide me with a KDZ file, I have the latest version of this phone (VS50020I and VS500PP8). I'm using LG Firmare to download. I am very frustrated, I am using Lg Flash 1.8.x I need the latest version of this program
