I bought the LG G2 from a shop which sells refurbished phones in my country.
Knowing that the phone was the D802 model according to the software info in aboout phone and the the writings on the back of the phone, i tried to manually update to Lollipop for D802 which brick my phone.
When i was trying to update to lollipop i had noticed that the phone was rooted, therefore i thought that was what caused the brick.
After alot of tries without result i decided to use the short the capacitors as shown in the guide http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 which enabled me to use the ubuntu commands to send the partition images.
Out of knowledge, i kept sending images for the D802 model which i was able to get into download mode, but when i try updating the phone again with the stock firmware i get a brick again, and had to repeat the process again and again with no luck. at some point the phone did not turn on, it did not charge, it just wasnt booting not even the screen was turning on, but when connected to the pc it was recognised as qhsusb bulk, but didnt respond to the commands in ubuntu.
i ddnt give up, repeated the process of shorting the capacitors and finally it turned on and was recognised in ubuntu.
After all that, i decided to go through the phone and that is when i noticed that it was not a D802 model, infact it was made from different parts from different models as shown in the images below.
i currently have slow connection, later i will download the firmware for the D801 model and try to update as the mainboard is of that model then i will edit this post for feedback.
I guess this post will help those who have bricked phones and have tried to flash different firwares with no luck.
Edit: i tried to flash the stock firmware through the lg flash tool but it failed
At the end i i got my phone fixed by flashing the partition images of the D801 through ubuntu. However, for the boot, aboot and recovery images i used the ones i extracted from one click root for D801 thereafter flashed a debloated stock rom through twrp. Byt after booting up the phone shows as F350k
First thing to do dude is put it all back together and wait for somebody who knows what they're talking about to come by here.
I had exactly the same problem ,flash the firmware for the D801 model, you will be fine .

Dear all,
and thanks in advance to anyone willing to spend some time to help me.
It all started few days ago when I turned off my LG L9 (updated to the last version available for my brand (Italy - TIM), I believe it was Jelly Bean V20C).
When I turned on the phone again, it was stuck on the lg logo.
Then I started to read this forum, and the first thing I tried was the HARD RESET. After that, a sadly image of the android robot with a red triangle lying upon its body appeared.
This image now shows up every time I boot my phone, just after the LG logo.
Then I tried:
- recovery from LG Mobile Support Tool
- followed this guide: [GUIDE] [UNBRICK][ROOT] FLASH Any LG Factory ROM (kdz) WITH OFFLINE FIX
- tried KDZ update tool alone (3GQCT in combination with all modes: DIAG, EMERGENCY, CS_EMERGENCY).
In order to use the Offline fix guide, I run fastboot with option number 2, to upload ICS x-loader and u-boot, otherwise the phone was not recognized by the tool (_IsConnectedPhone(0)).
But in all cases of kdz update, the phone reboots at exactly 90% of the process and after the initial LG logo the red triangle is back again .
Harder reset won't work either after the update.
I tried Italian firmware V10A_00, V10B_00, V10C_00, V20C_00, but none of them works.
I noticed that after the update to an ICS firmware, when I try the hard reset procedure, I can see the android recovery image just one frame before the red triangle appears.
I also tried to install a CWM recovery, but without the bootloader unlocked I got a "security error", that went away with a kdz update.
I searched this forum and I think I can't unlock the bootloader with a bricked phone, am I right?
I plan to make a last recovery with the LG Mobile Support Tool and send it to warranty, so that no trace of fastboot manipulations should be visible (right?).
I have read a lot of threads on this forum (and others) before posting here.
If you know of anything I can try, please let me know.
Thank you!
Absolutely the same...
I have this problem, too. Did you find how to fix it?
What happens during the recovery with the LG tool? I am sure I read about stopping at 90% and a solution somewhere here... search for it, I dont have the time, sorry...

i have the same issue .
at 90% phone reboots and red triangle dead android appears .
i think its a problem with the drivers . tried this on win 8.1 , 7 and xp on 2 different computers . same results .
i got the same with lg recovery and offline kdz method .
would be very nice to find a fix
I brought the phone to the warranty office. They substituted the "pcb main" so I believe it was an hardware problem.
Hello,
I got the same problem. Using the same methods and got no positive results.
Does someone solve this?
hello my friends. have any of you solved this problem?
i did exactly what op did, and no results.
I never had a red triangle issue. This probably neans that the bootloader is kocked AND encrypted. In the beginning this was the case with the US T-Mobile variant, and seemingly for all L9s from the final oroduction run. For other phones you needed to flash a certain stock rom, v10a or the first couple of v20s, then unlock the bootloader.
You should try using the CSE Flash mode from LG Flash Tool 2014.
I have the same problem, the difference is when i try to flash kdz it gives me error at 50%. I tried all the methods that op does but no succes. I also tried flashing img's manually from fastboot, i tried cwm and twrp as recovery.img and even extracted original kdz to img's and flash every partition manually. The system.img is the main problem cause you can't flash such huge file (1gb) through fastboot. Maybe someone have some idea is there any way to unbrick my phone? Bootloader is locked, and device had no root before brick.
If anyone can advise me here I will be very grateful. I have spent several days looking online and reading countless threads here but am still not having any joy. Am a bit of a noob so go easy on me please!
I have a rooted LG D618 running Lollipop (recently upgraded itself from Kitkat). Long story short, I was fiddling around with the bootloader trying to install a custom recovery (ahem... ) and I ended up bricking the phone. I have been trying since then to install the original firmware using LG Flash Tool 2014 and it always stops on the 4% mark whilst extracting the kdz. I have tried this about a hundred times and the same thing happens every time. The phone is completely dead, I can not switch it on and I am unable to boot it into Factory Reset mode using the keys either. But it is still being recognized by the PC (win7 x64) and can enter (what I assume is) download mode. However in Windows the phone is recognized as removable disk containing 2 folders - 'image' and 'verinfo'. Not sure if that is normal or not? I am able to start the kdz flashing process and it goes through the first couple of steps verifying connectivity etc and then stops at the aforementioned 4% during the file extraction process, sticks for a while, and then gives me an error message.
I tried a solution which I found on the forum here, which I think was for the same issue, involving the wx.dll file in C/ProgramData/LGMOBILEAX/phone but this has no effect. I thought it might be related to me installing the KitKat kdx (v10c) onto the phone but I have since tried flashing the stock Lollipop variant (v20b) also and the exact same thing happens so am guessing it is not because of the KitKat wx.dll file causing issues. I am pretty clueless here, all of this is unchartered territory for me and I am out of my depth so if any kind soul here can advise me on any possible solution I am willing to try anything before admitting defeat, and taking the phone to LG to fix under warranty and hoping they don't realize that I broke it. :laugh:
My Lg G5 (Tmobile) keeps on rebooting to recovery mode (TWRP) no matter what rom I flash. I tried using LG Up software but no matter how many times I install the driver phone is not recognized. Firstly I flashed Fulmics ROM then I installed LineageOS (Cyanogenmod) after that phone was working fine for a while till I saw an update and tried updating it to new nightly version. Please help me out if anyone knows how can I fix this issue.
You probably need to put the phone in download mode and then try LG up otherwise try pushing a rom that works through adb

I am sure this method would fix it but I already returned my phone and got new one as I had 1 year warranty. I bought it from T-mobile and I locked the bootloader before turning in the phone so it doesn't look like I was trying anything fishy. Now instead of phone going to twrp each time it goes to boolop saying "device is currupted and won't boot". It won't go to recovery mode no matter what I do and hope I don't get charged from T-mobile saying this and that.
However, I am really grateful to all of you great people who tried their best to help and you sir actually threw me a solution but I was too impatient to wait for it. I know this method will work no matter what as I had been using this tool for my G2 in old days and fixed the worse bricks where I had to openup the whole phone take battery out and stuffs like this. I was looking for this method found everything but LG tool asked me for .dll file which I couldn't find anywhere and decided to give up on it...
Thank you for your help and now I know I am not going to be bricked anymore as I have this method to work with in future issues and am her waiting badly for Xposed to be available for Nougat.

Good to hear that, You are welcome,
And as you mentioned about "device is corrupted and won't boot", that's because you locked bootloader. And as you were using twrp which means modified system partition so phone said that. But you can still go to download mode and use the method to make it live or can try unlocking bootloader to start twrp.
I experienced similar situation. I thought I had to send my phone for repair. As I was able to put the phone to download mode, I used uppercut with downloaded kdz file from LG G5 development thread and restored my phone. I didn't use my phone for four days thinking that I had to take to a phone shop or send to service center. But after careful reading of unbrick tutorials, I brought my phone back to life. Now I can play flashing anything as I am confident that I can easily unbrick my phone.

A few days ago I got my G5 H830 and came with version 6.0.1 h83010i, looking for information on how to install custom rom, I read the post to install the .TOT file to be able to install TWRP and through this the Custom Rom, until there is Everything okay, I did everything right, but then I decided to go back to the Rom stock, on the night of that same day I saw that when I reboot my cell phone it stuck on the LG logo and it had some color pixels damaged (but no screen Damaged, if not because of small brick) then force a restart and continued the same, I did factory reset by stock recovery and then normal start, I went to sleep leaving it in 100% battery, and when I wake up in the morning the cell phone It is off, when I turn it on 5% and I get scared, then I wanted to go back to custom rom to leave those problems behind, but then when I install the TOT again and install the custom ROM it will restart half installed and any rom that installed it would stay Stuck and the LG logo and a bootloop until when it was flash the kdz several times until the cell did not want to ignite more, the pc does not recognize it or anything, I need help with this.
Hello guys and gals, so i just recieved my LG V10 H901 and tried to follow https://forum.xda-developers.com/tm...step-step-guide-rooting-lg-v10-using-t3382631 this guide, but eventually i ended up with a brick after trying to flash the .tot file.
I keep getting
Boot Verification Fail
- cause: MISHMATCH_SIG_LEN
The TWRP recovery i had is now gone, and i can't access Bootloader. I can enter Download though. I read a lot of things around the problem, but i always stuck on various software versions or phone versions i can't really understand. Is there any way to get the phone back working? Before i try any method i just want to be sure i wont mess even worse (if that is even possible).
I tried UnbrickMe thread, but it says only for soft version:h90120j I have soft version H90120c (i haven't performed the update to MM) so i don't wanna try without being sure its going to work.
I m leaving for vacations in couple of days and i don't have a phone :/ please give me your lights.
Also LGUP wont see the phone, the same for ADB.
OK I Fixed it!
I was able to get out of this maelstrom of bootloops and to finaly flash the default ROM (you can find it here https://forum.xda-developers.com/tmobile-lg-v10/general/stock-h90120j000712-kdz-t3436249 )
So what i did is to remove battery for 10 seconds
Put The battery in
Hold volume up button
Plugin the phone to my PC through USB
Then download mode will start
I opened LGUP and fortunately it was able to see my phone.
Then went to Upgrade and flashed the kdz file.
All went smoothly and the phone is back working.
Hello everyone, I have been a fan of your forums for quite a while, you guys have an awesome community. I have been attempting to unbrick my VS990 with no success, I have LGUP and all of the proper dll files in the proper folders, I have two .kdz. One is the stock kdz, I can not get to work at all due to anti roll back (no matter which option I choose) and the other is the current kdz. I got that one to accept using update, but it did not fix my phone, it is still stuck in boot loop. and using refurbish I get an error message saying that it is not supported by that kdz. LG UP is fully recognizing my phone, I found the .kdz files no problem, I believe that I have followed all of the steps here >> https://forum.xda-developers.com/lg-v10/general/guide-lg-v10-stock-firmware-to-stock-t3224170 any help at all would be appreciated. Side note, I have not rooted or installed a custom recovery.
I would also like to add, I can not do a hard reset. Every time I attempt the phone either locks up when I hit the power key on yes to confirm factory reset, or sometimes it reboots to LG splash screen and locks up then. I am starting to wonder if there isnt a hardware problem with the phone instead of software.
