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.

Hello everyone,
I've searched everywhere I can think of to figure out how to solve my problem, and I assume the answer is hiding in an obscure part of an earlier thread on these fora. I was able to root my L9 P760 running Android 4.1(Jelly Bean) and from there naively assumed I could flash the recovery using ClockworkMod. After rebooting I've been getting the infamous "Security Error" screen. I've been able to get the "S/W Upgrade" screen, but that's as far as I got. I believe this means the bootloader is locked.
I followed a lot of instructions I found including using fastboot via omap4boot(http://forum.xda-developers.com/showthread.php?t=2119090) and the offline kdz flash(http://forum.xda-developers.com/showthread.php?t=2085344), but without luck. Fastboot would cause the phone to reboot, losing the "S/W Upgrade" screen and the kdz method would stall at 4%, leading me to find out that the phone needs to be in the "LG Update" USB mode, which I can't achieve because it won't boot.
I have two Macs running OS X 10.7 which can dual-boot into Windows 7. All software is up to date. I have experience using the command-line.
I hope there's a solution to this, and I hope that posting this here can help others avoid this problem in future.
Thanks in advance,
Pieter
Edit: I finally managed to flash a stock version of recovery, the x-loader and u-boot for Jelly Bean using the fastboot script from here. For those in a similar situation, I set the driver for the OMAP4xxx device which goes under TI devices(or something like that) and then I had to set the driver for a device called LG P4(or something, I didn't take a screenshot). I was then able to use the stock LG Mobile Support Tool, via the "Recovery Phone" option, to restore the newest version. However, it still won't boot properly. I get the LG logo when turning it on, and then the animation with the LG logo with the shiny effect on the smiley face keeps running in a loop. Is this the boot loop problem I've seen people asking about? How do I access recovery(and would that accomplish anything)? Any help would be appreciated.
Edit 2: I think I fixed it! I'm just documenting what I did to be helpful to other people. I had tried to do a hard reset earlier, but it didn't work. I tried it just now, and it worked, I got an droid with a progress bar underneath. Then it booted, and I heard the startup sound which I didn't know I was missing. I would still like to know in detail what I did wrong, and what I did right, and why it was right. Thanks in advance.
Simple, you probably did nothing wrong. Things just happen. I had this happen to me once. Security Error
However, I didn't install a custom rom or recovery img. All I did was flash a different kdz version (for my device). So my guess is that the boot img or other img, got corrupted.
I fixed my issue by flashing x, u, boot, recovery all in fastboot. Then I ran the flash update program again and it worked

How do you brick your phone. Did you try to hard reset it? Did you try offline flash or LG mobile support tool to recover your phone?
I probably just did something, that is supposed to be impossible. I bricked my LG L9...
I had 20f soft with root and tried to unlock bootloader using some method, that is about flashing KDZ files of V10 and V20 roms using offline mode of LG Support Tool.Well it looks like something is not right. After the whole process, the device rebooted aaaand stuck on the second LG logo, I thought it was fine, just need to hard reset but no. Now, when i try to hard reset i get the "dead android"with the red sign, and every rom i'm trying to flash using this offline support tool gets only to 50% and then says, that the device is no longer connected (?????). I tried to get back to stock rom using support tool recovery but same here. 50% and nothing more. Today, i've bought 910k cable, heard that may help but i'm not sure how to use it.
If anyone is able to help, i would be very grateful. And sorry for all spelling mistakes.

did you try fastboot method? that pretty much will get you unbricked
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 .
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:
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.
