How to Unbrick your LG G2/G3/Flex from hard brick - G2 Q&A, Help & Troubleshooting

This guide is for an hard brick with these features:
-no download mode
-no recovery
-no fastboot
ONLY STUCK AT LG BOOT LOGO!
THIS GUIDE IS ONLY FOR EXPERT USERS I DON'T WANT ANY RESPONSIBILITY
I followed this guide ( http://forum.xda-developers.com/lg-g2/general/fix-unbrick-lg-g2-stuck-qualcomm-hs-usb-t2933830 ) but it is incomplete, I have found the right method to extract TOT files and to use it for b2bextractor program (in the guide). With that guide i followed you can force your device USB port and at the end the download mode finally (this worked for my LG G2 D802)
If you use different or wrong TOT files the cellphone will be unavaible forever
If you have the same problem with your phone contact me , my email is : [email protected]

Lg g2 broken download mode

guyz i need urgent and seriosu help...im totally helpless
i give my friend g2 f320s..it rooted and updated so its download mode recovery mode all had been corrupt so i revive its phone through Linux Method..
Now again my friend install i dont know g pro recovery or i dont have confirm info but now its phone stuck at Lg boot animation...no recovery only lg Lg Service ..so i tried to flash kdz but strange thing is it only shows download mode first logo not second..im attaching pic if somebody dont understand...so what i have to do..how can i flash it ..waiting for ur reply
install lg flashtool on your pc, download dll and tot filles.then kdz it.

[Alternate solution] Lg g2 vs980 recogniced as model L01F

Yesterday I installed this rom:
http://forum.xda-developers.com/lg-g2/development/lollipop-grola-rom-5-0-1-t3028569
And after it "finished" the phone got stuck in a fastboot screen, and the usb was not working, neither the recovery nor the bootloader.
So I really screwed it up, the I followed a tutorial in youtube to fix corrupted qhsubs , It was awfully hard to make my device to work, so now that I'm finally capable of entering into the bootloader when I use the lg flash tool with kdz, it gets stuck at 2%.
If i try to flash via tot+dll it shows that my lg model is the L01F.
I have read about doing a cross dll editing with a hex editor, but I have tried and I dont get to work neither the dll nor the tot file
***************************************************************************************************************************************
The posible solutions
There are many posts out there to edit with hex editor, in order to trick your phone to install the rom, also there are posts that will indicate you ro reflash all the .img again by killing the bootloader and entering in fastboot mode, but at least for me none of this worked.
The solution that worked out for me (thanks to Ayala's Inc youtube channel)
What you will need:
1-Lg flash tool for TOT files
2-Generic DLL
http://www.mediafire.com/download/vh6y1unm9fq8vtx/LGUP_8974.zip (893kb zip)
3-.tot image file that you are going to flash
http://storagecow.eu/index.php?dir=Xda%2FLG+G2%2FStock%2F
Note, if you are in this post, then you will realize that the .dll that are in the link above are not working for you, you must instead use the generic dll that it's in the zip.
How to flash, now this part is know by almost everyone:
1-Open flash tool.
2-Check the "select manual mode" box.
3-Load the generic .dll in the DLL part.
4-Load your image .TOT in the s/w part.
5-Do not modify anything else here.
6-Connect your device in download mode
7-Go to device manager
8-Scroll down below to Ports (COM and LPT)
9-Right clic to your device and select properties (Lg mobile usb serial port)
10-Clic in the port config. tab, then click in advaced options
11-Set the COM port numer to 41 and accept.
12-Now back again in the flash tool Click in the yellow arrow that is in the top left, and wait, if it doesn't start the process automaticaly, disconect your LG (keeping the download mode) and reconect it to the pc.
13-Wait for the process to finish, after the proccess is over, you will be able to flash any stock rom, your LG g2 will no longer be confused about its model.
*If the kdz lg flash tool stucks at 2%, this will be your solution.
*If the TOT lg flash tool doesn't flash because the rom/dll/phone is diferent this will help you to solve the problem
This might work with all the variants, I haven't tested, but it should because it's the generic dll file.
There it is the video, that helped me out, credits for him, he told me about the .dll solution
I can't visualize the video correctly so here is the link:

[Guide] Save LG (isai vivid V32) from [Security Error Authentication Fail #9]

Hi~ guys, I am an android phone user from China who bought LG G4 Japanese Edition [LG isai vivid V32] last month.
After delete "google play service" in system, then reboot, but the device shows [Security Error Authentication Fail #9]
and automatic started again and again, Ops~ device bricked, GG! :crying:
As we know the resources and softwares are not friendly to LG isai vivid V32, the Firmware is also rare, cos I can't find any tip for LG V32 in XDA,
So it is more difficult for us to save the bricked device.
Due to the [Recovery Mode] still can't solve this problem, here we need to use TOT Firmware to go back to stock,
KDZ is also available to reflash, cos I didn't get the KDZ Files, so I choose TOT to reflash my device.

Replace the old MegaLock.dll file to unlock.

Some Tips for LG G4 Japan aka isai vivid V32
1. ROOT
After reflash TOT firmware,the system is rooted.
so you don't need other app to root it.
If you can't get the access of root, [360 super root] and [KingRoot] would help you.
By the way,a part user of V32 say, they got bootloop after use Kingroot.
and if you load 360super root, then you can't use [Super SU#]
2. Recovery Mode
The correct way to into [Recovery Mode] is:
1) Power off device
2) Press and Hold [Vol - ] and [Power button]
3) When screen shows logo, keep press [Vol - ], release [power button] for one second, then press and hold [Power button]
4)then screen would shows [Factory data reset]
Really appreciate your effort, come from v32 tieba, LOL, wondering why my g4 charges very slow. It only charges at the rate of 0.3a and 4.2v which is unbelievable considering the fact that it supports Quick Charge
still error

STOCK ROM
Hello everyone!
I know this phone barely has stock rom files available for download but I want to know if any of you have the marshmallow version LGV3220g to download.
I'm stuck with 5.1 and I can't even update it on OTA because I'm not in Japan...
