[Q] Bricked verizon lg g2 by install software update, don't know what to do

Hi guys, I got my LG G2 a few months ago and it was my first android phone. Since I always jailbroke my apple devices I decided to root my lg g2. Everything worked fine until last week when I was prompted to install a software update. I thought this might mess up the phone since it was rooted so I postponed it until later in the day to give me time to research, but I forgot to postpone the update again and it went through at the scheduled time. Now when I turn my phone on, the lg logo is displayed, and then I get a boot certification verify error. I don't really know what that means but I can't do anything, no recovery, no download mode. I started to follow this tutorial but am stuck at what files to download. I do not know if I have the 10b, 11a, or 12b variant, and I can't find a way to check it without turning the phone on, which I can't do. I'm really lost at what to do at this point, I can't follow the only guide that might fix my phone. Is there another way to solve this issue or find which variant I have? Would verizon accept it back to fix or replace it since it's been rooted? I've read some people saying they unrooted their phone and then returned it to the carrier, is it possible to do that in my situation? I really need some help guys.
TBH: I would call Verizon, and tell them the phone was bricked by the update- hope they don't notice it was rooted when they warranty it. Problem is, if they do you get charged full amount for phone. I'd consider if you have insurance to just claim it on insurance.
try download lg support tool from lg website http://www.lg.com/uk/support/software-manuals
plug the device and wait for the software to recognize ur version.
I downloaded and installed it, but it won't recognize by phone. I have installed the drivers for it
ok.
try to follow this guide http://forum.xda-developers.com/showthread.php?t=2681089
and the files download from here:http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware/10B_Partitions
lets try this virsion and see what happend..
download the 10B zip file and the dll file too http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware
now it doesn't boot at all, not even to the lg logo. Additionally the partitions don't show up in ubuntu any more. I guess i'm completely screwed now?

Problem with updating H870DS over LG Bridge

I am trying to update my lg g6 h870ds over LG bridge it is update from 03.08. but i am constantly getting message "the update cannot be downloaded because there was a problem with the server"
Does someone have solution for this problem, thanks in advance.
I have the same problem, I am upgrading via LG Up at the moment. See https://forum.xda-developers.com/showpost.php?p=73288571&postcount=225
Sigh... Another thread on this subject. Really? The solution is that LG fixes their servers. Can anybody here do it? No? Well, too bad. Let's start another thread so that we can discuss it in depth.

adding 203.247.157.64 pkg03.lime.gdms.lge.com to the host file will work.
I tested, but download very slow 200kps for a ~3Gb size. Takes about 5hrs
Other method is using kdz, the link is from here https://www.reddit.com/r/lgg6/comments/6rcn5t/lgh870ds10e_update/
If you have IDM use it , takes about 30'
then use lgup, https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
and undercut https://forum.xda-developers.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295
After install lgup, run undercut, you won't get any error.
Don't forget to choose upgrade option before proceeding if you don't want to loose everything.

LG Bridge Backup does not support my G6

Hello to everyone,
I just wondering why LG software backup does not support my G6 (brand Vodafone).
I can check for updates etc etc but I can't do a backup of the device because software tell me that G6 is not supported!!
Someone can help me to solve this problem?
Thanks in advance.
I have the same issue, any ideas?
Today I guess I found a solution.
I have installed via LGUP the firmware V10t (no brand), made 2 hard reset and magically LgBridge now support my device.
Unfortunately all the bloatware is still present but I am able to do a backup.
I don't know if some hard reset can solve the problem without flashing firwmare .
Try this.https://forum.xda-developers.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295
Thanks for the info but my device has only an issue with LGBridge Backup.
The solution already posted does not seem to work. Today LG Bridge continues to report my G6 as not supported by the software. :/ :/
I think the reason for mine not working is that I removed some of the LG bloatware, probably some of it needed for the communication with LG Bridge when connected to PC.
In my case, I don't think so because I debloated the device and Lg Bridge worked with no issue.

Help needed to flash LG G6 [H87110o]

Hi everyone,
Just a month ago I purchased what seems to be an AT&T branded LG G6 from ebay. The seller assured that despite the latter the device would've been usable in the UK (where I reside) and that is true as I can use my sim and make calls and send SMSs. I lately faced the charging issue due to moisture and fixed it by purchasing a new charging cable, but I the view of that I also want to flash my current firmware to a Uk unbranded version.
I visited the following [wesite](https://lg-kdz-firmware.com/download...10l/18642.html) to download a GB kdz file for my device but I was then taken to this other [website](https://lg-firmwares.com/) where I located an [EU Oreo kdz](https://lg-firmwares.com/downloads/d...477f64fee0d181) file. I then thought I might as well get this one and flash once for good.
I then downloaded LG UP software and tried to flash my device. Initially, I was facing the 'can't load model' error which I then fixed with the [uppercut software](http://www.**********.com/make-lgup-...uppercut-tool/). Once ready to flash and I get an error message reading "error: kdz file is invalid H871 -> h870".
Can anyone help me with this? First of all, I'd like to say, despite all the props to the developers that created these awesome tools, I couldn't find a single official and complete guide on the LG UP tool. Can anyone please provide me with an accurate guide for LG UP?
If the kdz file that I'm using is the issue, can you please provide me with the right firmware files?

H873 still doesn't have Oreo Update?

Hi Everyone!
I recently got an H873 LG G6 but it looks like the oreo update for it has still not shown up. I read online that this model received the oreo update a while back (a few months ago).
I tried using the LG USB Bridge software but it gives me an error.

Note that I have installed the PC drivers. ADB works just fine. USB Debugging is enabled.
Can anyone help me out here?
Here is the link for the firmware, if you have everything working now you should have no trouble loading the firmware https://lg-firmware-rom.com/
