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.

Hi,
I rooted my LG Vortex (no recovery installed yet), and deleted bloatwares such as Verizon Navigations and other apps. It was running great for the last two months until I reset my phone. After resetting the phone, I can no longer log in to my phone. After the phone is turned on, it tell me to choose the language and activate the phone. Then, LG Setup screen showed up and when I click next, it says unexpected error occurs and went back to choose language screen. I think I might have deleted something that is required to setup LG welcome screen. Is there anyway I can do to get the phone working? Any advice would be appreciated.
if you really did delete something essential, i think you should start back from scratch. find the kdz file for the lg vortex and flash it using kdz updater (of course, research this stuff first because while kdz updater is used to flash your phone, it can also brick your phone if you're not careful)
btw, heres how to get your kdz file:

Thanks sweetnsour. Unfortunately, I cannot find stock ROM for Vortex there. One more potential problem is that since can't log into settings, I cannot turn on USB debugging mode. I do not know if USB debugging mode has to be enabled to perform KDZ flash.
This is the error message that I received at the welcome screen.
"The application com.android.LGSetupWizard(process com.android.LGSetupWizard) has stopped unexpectedly. Please try again."
i know this reset might be similar to what you did, but i want to try all possibilities of saving your phone before we go into the hard stuff:
turn off your phone, hold the home+vol down+power. it should boot into the stock recovery and do a reset (i believe, at least this is what happened to me)
and if that doesnt work, check your pm.
heres a better guide (i shouldve posted this earlier, sorry), this should clarify some things

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.
Hey guys, I've got a T-mobile v10 (H90120j) on 6.0 and on the most recent update as of 8/22. I tried to root via the LG UP method, but something went pretty wrong pretty quickly(I'm sure I mis-interpereted a step or made some similar rookie mistake). I'm in a boot loop of the "Your device software cannot be checked for corruption" no matter what I try to do. Luckily TWRP installed, but when I tried to reboot to finish the LG UP method it told me there's no system. When I connect it to my computer it shows as v10, but only the TWRP folder is visible on it. I was trying to find just a stock rom zip, but the ones I can seem to find are the ones that use LG UP using tot files, but I can't get the phone to go into download mode. Then I found stuff for the h90120e, which evidently hard bricks the phone. Does anyone on here know anything about this? Its not fully bricked but since it wouldn't mount the system properly, I wiped everything and repaired the system files on TWRP so I'm on a totally clean slate now. ANY help is greatly appreciated
**UPDATE** Tried installing Bliss rom, and had no errors, same with gapps. I'm still stuck in this boot loop though; I cant get past the "your device software cannot be be checked for corruption" screen

Was this thread ever resolved for you k.wise, having the exact same issue just about with my v10.
The problem at least for me is the system partition of memory isnt even mounting and in turn is throwing error 7 and not allowing anything to be installed or read on it.
[SOLVED] My LG v10 is in a bit of hiccup because of this. I have tried multitude of things with still no solution.
I have attempted to go into the mount of menu of TWRP and mount the system, after mounting I have tried everything from reinstalling a rom, wiping it, resizing, restarting to system, a few terminal commands, and they all lead to same exact scenario. The phone restarting, flashing the lg logo for half second than going to "this device software cant be checked for corruption" yellow triangle screen till TWRP comes up.
I have also tried 3 different versions of TWRP, installing kdz files, using an lg bridge/up update, and also some prayer. The only thing that has ever gotten me close to getting this baby back into shape was the lg bridge software update in download mode. Brought it to full startup from system but than ended on a white screen asking for a password 30/30 attempts to get into the phone, and I don't have encryption and even if i did it would be gone after the numerous factory resets and data wipes.
Are there anymore possibilities for me to try? The problem seems to be the system partition not mounting in most cases but I seem to have a reached a dead end.
Edit 1 w/Solution:
What ended up solving the problem (bad firmware, anti-rollback stopped me from going to a good one) was the following post by tungkick (THANKS TUNGKICK), once I got the microsd card ready and in the v10 I than put the phone in download mode (volume up + battery + usb to comp).
From there I used the lg bridge tool to detect the phone and than update back to stock. The key thing is i didn't chose the regular update option I chose the option on the bottom right (of my lg bridge application) that said update without error recovery I believe (sorry updating this away from home so I can't remember exactly). Once the update was done there was no screen with asking for a password, no bootloop, and so far no problems with the stock software.
Hopefully this is helpful one day to someone with a bricked v10 and almost gave up hope like me.
That happened to me when I tried rooting, I flashed the latest official kdz (select update) to get the official stock rom again

Click to expand...
Click to collapse
Tried that and flashing tot files, feel like I cant do much unless I can install the /system partition on start up or get through the anti rollback settings.
As of now I can use twrp fine and get in download mode. But that seems to be it
Dunno what to say, do you have the latest version of lgup?

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.
