I have made this tutorial due to me not finding any other tutorials on fixing the problem presented in this guide. Dear admins if there is another guide on how to fix this problem please feel free to do what you must to this thread. Thank You
First of all is if you have the security error problem on your phone I can assure you that it is NOT bricked and can be fixed.
Also I am not and will not be accountable if this guide does not fix your phone. I also will not and should not be held accountable if this guide is to further damage anything of your phone.
PROCEED WITH CAUTION; Please Pre-Read this guide and understand it before proceeding.
Okay so I will guide you through on how to fix the security error problem most people have on their LG devices. I had encountered this problem on my friends LG MS769 (Optimus L9 – MetroPCS). This guide should work for mostly any LG phone.
This happened to me when I was flashing a custom recovery for the phone. I had successfully rooted the phone using a guide located at:
androidforums.com/optimus-l9-all-things-root/759935-how-root-metropcs-l9-lgms769.html
By following the above guide you will be able to successfully root and install SuperSU on you LG MS769. But keep in mind that even though it will root the phone is will NOT, I don’t know how to emphasis this as much, it will NOT: Unlock the BootLoader, Flash a custom recovery, or let you install a Custom Rom.
But let us come back the topic at hand. Okay so to fix this problem we will need the following.
LG Mobile Support Tool -- B2CAppSetup.exe -- Attached
A reliable Internet Connection
A computer with Windows XP/Vista/7/8 – (Untested on Windows 8)
TIME and PATIENCE --- We will be downloading a file about 500MB give or take some.
Okay let us begin in our endeavors of fixing our problems.
First use the below download link to download the LG Mobile Support Tool
After downloading that place it on your desktop and run it as administrator
After you run B2CAppSetup.exe it should automatically open the Mobile Support Tool, if not there should be a new .exe created on the desktop called LGMobile Support Tool just double click and open that.
Let the program update and install any necessary files that it requires. (It should automatically start to update and install, it should just prompt you with a UAC window)
Once you see the program open, click on the Install USB Driver button on the top left-hand side
Then a new window will come up asking for you for the phones carrier and the phones model number.
Once you are successfully done installing the drivers, we can proceed to the restoration process of the phone
Okay now we need to put the phone in S/W Upgrade Mode.
a.Remove phone battery, if it does not have a removable battery make sure phone is off
b.While holding down the VOLUME (DOWN or UP or BOTH) BUTTON(S) insert the microUsb in the phone while also having the USB side connected to the computer already. (To enter S/W mode it varies phone to phone which volume buttons must be pressed, try all three options)
Once the phone is in S/W Upgrade Mode the computer will start to install the drivers and the LG Mobile Support Tool will automatically detect it and start the restore process
a.Keep in mind that this process takes its time and should more than likely complete successfully giving you a working phone
b.NOTE: I have read some people calming that the process gets stuck at 4% and does not go on. If it does happen to get stuck at any percentage let it stay there for a while and see if it does go on, if not I would recommend retrying once on the same computer and if it still does not work I would give a second recommendation to try on another computer. Other than that I would suggest you contact you phone carrier or LG.
If all goes well you should have a fully functioning factory restored LG phone. Congratulations!!!!
Hope this guide was of help and I wish you best of luck in your further endeavors. :good:

Security Error corrected!
Thanks for this info! I was able to update the SW from the LG Support Tool program but I had to switch to another computer to do it, and after several tries it finally took.
For this LG-P769 I had to hold the volume up button with the battery out and it went into the SW update mode on the phones screen. The update stopped after 33% update and I had to disconnect and install the battery, start the phone and let the Security Error extinguish, then plugged the USB cord back in and click the retry button of the tool, then it updates. Yes!
Note, wait until the phone reboots to the normal operating screen even though the tool says its done. This tool approx. 2 more minutes.
The phone is no longer rooted but it kept all the original apps except "Superus".
Not working for me, any help?
I have an LG-LS970, and I've made it to the point where the recovery software was downloaded and extracted, but something is causing an error and not letting the process finish. I assume this is the faulty ROM on the phone, since my phone is bricked from rooting and deleting Google Play apps (I was stupid and thought they weren't important to have). Any ideas?
If you had the recovery software installed you could of installed the gaps. Zip files through it.

Please help i've been at this for 2 days
I moved a boot.img file to my Metropcs LG optimus L9 lgms769 and now I am stuck at the security error. I rooted the phone but did not have the bootloader unlocked. I have tried the update tool and it stops at 4%, when I can get it to work. I haven't either understood the other methods mention or something, idk. Anyway, I would really like to get my phone working. Can someone please give me a good way to do this. I have the V10E_00.kdz file already. Thankyou
I already have the latest version but need to repair
Thanks for the instructions! I followed the steps and everything basically works but once the phone is in software upgrade mode, the LG tool just says "Your device has the latest software available from the LG Mobile Support Tool" and it doesn't install anything.
What happened is I rooted my phone and removed one too many system apps, now it won't boot up anymore. How can I get this tool to reinstall the same software I already have? Do I need to wipe it completely? Please help me out, I'm afraid I'll make it worse if I try anything else.

Thank you so much! I totally overlooked the recovery option in the tool. 30 minutes later and I have my phone back working perfectly. So happy! :good:
I took it to the T-Mobile store this morning and all they wanted to do was sell me a new one, saying the phone was dead. I owe you. Can I buy you a beer? Seriously, if you have PayPal I'll do it.

Is it working? My phone is in S/W Upgrade mode, but I don't see any upload bar anywhere
Background:
I originally had CWM and custom rom install on my phone. I decided to install a new rom, but the installation failled and Aroma installer kicked me out of recovery. I have no way re-entering recovery, so I used Smart Flasher and the correct ROM to flash the phone back. And now I'm stuck at Security Error.
Hello to you all I am making this flashing tutorial since I have seen enough people asking how to flash using this tool.
This tutorial will be 100% detalied and noob friendly, with pictures. So fasten your seatbelt and let's go.
1. Disclaimer:
Code:
I am not responsible for bricked devices, dead SD cards, thermonuclear war,
or you getting fired because the alarm app failed. Please do some research if you have any
concerns about all contained in this tutorial before you follow it! YOU are choosing to
make these modifications, and if you point the finger at me for messing up your device,
I will laugh at you. But since i'm a nice dude i will try to guide you anyway:)
2. General info:
This can be used to flash a new firmware that you will download from LG firmware website. You can upgrade/downgrade your current version.
This can be used for every situation that can get you in a working Emergency mode/Download mode.
This will work/not work (I didn't test) on versions grater than Windows 7 both 32 and 64 bit. I am not going to give support to Windows 8/Windows 8.1. If it works for you it's nice. If not I will ignore the posts like "What can I do not working on Windows 8" and so on. Same thing goes for WINE (windows loader for LINUX). Use this with Windows XP or 7.
3. What we need and getting ready:
a. Firstly, we need the Drivers for our Phone. The drivers I am attaching must be universal for LG but if they do not work for you then you need to search the drivers the manufacture made for your device.
Universal Driver for LG (TRY THIS FIRST BEFORE YOU GO AND DOWNLOAD FROM LG WEBSITE): LG Drivers.
Install the driver (the one I provided first). If your phone is not detected then search on LG website.
*If the ones I provided don't work you can fine the ones for your phone here: http://www.lg.com/. Search in the right up corner the model of your device. Select it. At download section (in the right of the mini-phone picture) you will see Software Updates & drivers. Select that and download the USB Drivers for Windows.
b. Secondly, we need the KDZ image that you want to flash. I am not going to provide any; you will download the one that you want FOR YOUR DEVICE (do not use any KDZ not intended for your device) from here: http://lg-phone-firmware.com/.
Press on the phone you have and download the image you want.
c. In the third place you want to download the tool: LG Flash Tool 2014.
*You need Winrar or 7Zip or any unraring program. Unrar it.
4. The actual flashing:
A)YOUR PHONE SHOULD BE IN EMERGENCY/DOWNLOAD MODE. The keys to do this are different from device to device so search the forums for your key combination. I will provide the way to get in Emergency for the L7 II and maybe L5 II and L3 II. Think this is the same for the first gen devices but can't confirm.
*With the phone turned off (I suggest to pull out battery for 5 seconds then put it back to be sure) hold Volume Down button and plug the USB cable that you have in your PC. If this doesn't work try holding Volume Down + Volume Up and plug the USB. If this doesn't work search the forums. You might also have a hard bricked device and this method won't work then.
B)Place the KDZ file you downloaded the 3.b. in the same folder that you unrared at 3.c. and Run as Administrator. (BE SURE TO HAVE THE KDZ FILE IN THE SAME FOLDER AS THE TOOL. The file i took for example is "Stock JB ROM.kdz").
*If you can't open this program then you need to instal this: C++ Libraries.

}
C)This will appear. Leave all the way it is and press the little folder in the right.
D)Select the KDZ you placed at point 4.B. and press Open (DO NOT SELECT RA or RC KDZ).
E)After you pressed Open you are back to the main screen you saw at point 4.C. Good.
Press Normal Flash (the left option) if you want to flash new KDZ preserving data (no data will be deleted). I do not suggest this because you might get a bootloop and you need to hard-reset (will wipe data). Always have all data backed-up.
Press CSE Flash (recommended) if you want to flash new KDZ with full wipe of data.
After selecting what you want you will get this screen.
Press START.
D)After you pressed START you will get this. DO NOT CHANGE ANYTHING, press OK.
E)Another dialog will pop and will flash your phone. First it will check USB connection but you already have USB connected when you got in Emergency so you should be fine. I assume you checked drivers at the Driver step so I assume there will be no problems.
IMPORTANT: DO NOT EVER DISCONNECT THE DEVICE EVEN IF YOU THINK IT'S STUCK, THE WINDOW GOT BLOCKED, IT DOESN'T SHOW ANYTHING OR ANYTHING ELSE. YOU CAN DESTROY YOUR DEVICE DO NOT UNPLUG AFTER YOU PRESSED OK AT STEP 4.D. WHEN THE DEVICE REBOOTS LEAVE THE USB IN FOR 2 MORE MINUTES THEN YOU CAN UNPLUG.
F)In some cases you might get a bootloop after 4.E. is completed. All you have to do is hard reset your device. Search the forum for specific hard-reset procedure. In P710 it's like this: with powered off device hold Volume Down + Home button and press Power. When you see LG logo stop holding Power. Keep other 2 buttons until you see android guy.
That's all folks and now the credits:

Trying to fix my LG Optimus L5 II
Hi guys, i'm having troubles with this method, tried both on win8.1 and 7 and i can't find a solution, maybe my phone is gone forever.
My problem is bootloop, and the phone isn't unrooted or modded in any way.
I'll explain what i tried:
-Hard reset (volume down+quickbutton+powerbutton) -> it only keeps vibrating an never showing the LG logo, when i release the buttons it just starts as normal (obviously bootloops).
-Update recovery with LGMobile Support Tool -> phone connects, firmware finish download, and then when it starts updating it just stops and says update failed for some reason.
-Flashing with LG Flash Tool 2014 -> It crashes after the extraction, maybe when it starts to flash.
thank you so much!!!
okay so, i made an account just so i could thank you for this tutorial and the software.
My LG L5 II (e460) was stuck in a bootloop and a hard reset did nothing for me. When i tried another flashing tut i got an error when the files were extracting in the lg mobile support tool. With yours i got the same error when i tried a flash with a full wipe of data to avoid the now dreaded bootloop. However when i tried a flash without loss of data it did actually do its job well. I work on a 64 bit with windows 8.1 computer btw. Once completed it did not give me a bootloop so it actually turned on, and thats a first in a long time. After that i did do a hard reset and now its as new.
So thank you thank you thank you! Thanks to this tut i am now able to gift my dad my once broken phone as if it just came out of the packaging!

You are welcome my friend. Usually this tool has problems on windows 8.1 (the errors you are talking about). With a Windows 7 machine works from first try. I am satisfied that I made your day. Peace out
Firstly - nice tutorial,really! Secondly - Why "LG firmware Updater Tool 2014" not "KDZ Firmware Updater" ? They are almost the same. And thirdly - from my expirience with KDZ reflashing on P713(was stuck with bootlogo), and also from 4pda comments, it's better to turn Emergency mode on phone(Vol.Down and then insert USB)(e.g. "Bootloader" mode isn't so easy to turn on as "Emergency"), - and Choose "Emergency" or "CS_Emergency" not "Diag" one) on step 4C. Also,if You're goin' to flash NON-cdma phone(as I know usually L7-ll isn't cdma),on step 4C it's better to choose "3gqct" not "cdma". And the last one - it should work on win8,but shouldn't work correctly via Windows 10 or Wine.
Have a nice day))

It is not cdma but doesn't have any impact. I can flash from emergency with Diag Mode also since the LG Modem is picked up in device manager in Emergency, so it should work.. Also I said that phone should be in emergency

Hello mate. Thank you for the tutorial. It's now very easy using LG Flashtool 2014.
All of the instructions worked for my L7 II P714. Now I have a clean stock JellyBean rom without the silly customizations from the Operator.
This L7 II has a very nice camera!
I got the clean JB KDZ from here:

Help me!
so i have an lg optimus l9 2 and it's stuck on boot loop i followed every step carefully but the lg phone software website does not work! i can't search for anything so i can't get the kdz required to fix this problem can anyone provide a link where i can find the right kdz for my lg optimus d605 model from germany? thanks :good:
The tool works 100% on Windows 10 (Pro, 64-bit, Creators Update). You don't need any special drivers, they are built into Windows 10.
There seems to be two problems. But fixing one will fix the other. So I'll go there first.
I can no longer get LGUP to recognize my phone. Fix this and I can reflash LGH962AT-ROOT and start over. My computer recognizes my phone and I can transfer files between them.
It is really hard to get into recovery, but I have through LGUP. My recent attempts shows the dead droid with the red triangle. I think I may have killed recovery and that may be why I can't use LGUP.
My phone otherwise mostly healthy. :good: I can't get Xposed to install and work. I had it working before my last reset. I accidentally killed my Contacts and Dialer. I can't Flashify/FlashFire LGContacts. 20/20 hindsight - I forgot to TB before messing with the Dialer/Contacts.
I am 100% willing to lose everything and start from scratch. If someone could help me get LGUP to work again I will be so grateful.
At least I didn't soft or hard brick it. . . . . . this time. (See my signature)
Can somebody help me to reconnect to LGUP? I have researched and found nothing that worked. (unless I did it wrong)
I'm begging and pleading here.

Seriously guys. I need help. I'll even pay for the help.
I give you my fix cause i had the issue to. 2 things. Lg up and drivers.
1. Download uninstaller from iobit
2. Uninstall lgup and its dll (use batch uninstall to uninstall at the same time)
3.once uninstalled you see an option called powerful scan. Click it and then delete all them files it picks up.
4. Install lgup and its dll file
5. Reinstall the drivers with the phone pluged in
6. Run lgup and it should work. If you need the files. The lgup tool plus dll and drivers i dont mind helping out. I really hope this helps
It almost worked. LGUP couldn't find my phone as usual. Then as I was about to give up, when it asked about Port and Version. As soon as I clicked to continue, it errored. I will try again in an hour. From scratch from your instructions.

2. Uninstall lgup and its dll (use batch uninstall to uninstall at the same time)
3.once uninstalled you see an option called powerful scan. Click it and then delete all them files it picks up.
4. Install lgup and its dll file
5. Reinstall the drivers with the phone pluged in
6. Run lgup and it should work. If you need the files. The lgup tool plus dll and drivers i dont mind helping out. I really hope this helps

I followed it to the letter. I think it might be my phone, not my computer. Again, I will try once more in an hour.

It almost worked. LGUP couldn't find my phone as usual. Then as I was about to give up, when it asked about Port and Version. As soon as I clicked to continue, it errored. I will try again in an hour. From scratch from your instructions.

I got a little hope. I got LGUP to not shut down completely. I am stuck on Model List COM3. Problem is it has Model Unknown.
Also, I am trying to contact LG Service & repair to see if they can save my phone.
Does the lg bridge software recognize it?
Sent from my LG-H901 using XDA-Developers mobile app
The LG Bridge helped a lot. My phone isn't fixed yet, but things are looking much better.
LG Bridge updated my phone to Marshmallow. Lost root of course. But I still don't have the missing programs, LG Contacts and LG Phone.
I uninstalled LGUP and Mobile Driver and then re-installed them. I got an interesting note.
*EDIT re-ran Mobile driver. No errors. I still can't get LGUP to recognize my phone.

When I updated to MM the "same" happened, it didnt install the apps I had deleted or frozen with Titanium Backup. I guess if we choose refurbish instead it will wipe the phone and install all standard apps

LG Bridge installed some of the programs I removed. The Google crap. The phone/contacts was not reinstalled.
Also, LG Bridge has no choice between refurbish or upgrade. LGUP does, but it doesn't recognize my phone. Now if I could get it to, then I could fix it myself.
:laugh: I got LG Phone and LG Contacts back. I did a Factory Data Reset and I got those two critical apps back. Unfortunately, I am still on Marshmallow, that doesn't have root, yet.
I still can't access LGUP. (Yes, going through the whole uninstall - install routine)
Is there another method of rooting / flashing LGH962AT-00-V10b- . . . -ROOT besides LGUP?
*EDIT 1* LG Bridge will let me restore from a backup. *.lbf / *.idx / *.brinfo Does anyone have a a H962 rooted Lollipop file I can use?
*EDIT 2* If I Enable OEM unlock in Developer Settings and remove the battery for a minute. Replace battery and do not touch the power button. Hold the Volume Up button and attach the computer cable and boot into Download Mode. Then open LG Bridge and click on software update. When it says I'm up to date, start LGUP I get . . . Model Unknown / COM6. (I did't do a uninstall - install of LGUP)
I'm getting closer. Tomorrow I'll do a full uninstall - install routine of the LGUP. Maybe I'll get lucky.

Well thats good you got it working. Sucks to be on mm tho.
MM is not bad, I dont miss root as much as I did before I had the LTE bands needed :good:
:laugh: :highfive: I got ROOT!!!! again.
For others here is what I did.
First, LGUP has an update. I downloaded it.
Linky-LGUPnew.zip Normal setup. Move the Common folder to the LGUP folder.
The Mobile Driver stayed the same.
I was on Marshmallow. But H962 doesn't have a rooted MM version. So I used my original rooted TOT. (LGH962AT-00-V10b . . . ) First I Chose UPGRADE in LGUP. I crashed my phone. I did it again but REFURBISH. I backed up everything via LG Bridge first. It worked! I got root, but I must restore my stuff.
LG Bridge did not restore anything for me. I stupidly forgot to also LG Backup via the phone app. It probably failed because I went from Marshmallow to Lollipop. It is worth it to me to BLOCK ALL %&^&#^% ADVERTISING.
DIE ADVERTISEMENTS DIE
So, I have no problem reinstalling everything from scratch. If you do, backup you backup's backup. I do have Titanium Backup of most of my apps/files. I "assume" they will work.
Now I have to patiently wait unit H962 has a rooted Marshmallow. Click thanks if this helped you.
Lord Sekhmet said:
There seems to be two problems. But fixing one will fix the other. So I'll go there first.
I can no longer get LGUP to recognize my phone. Fix this and I can reflash LGH962AT-ROOT and start over. My computer recognizes my phone and I can transfer files between them.
It is really hard to get into recovery, but I have through LGUP. My recent attempts shows the dead droid with the red triangle. I think I may have killed recovery and that may be why I can't use LGUP.
My phone otherwise mostly healthy. :good: I can't get Xposed to install and work. I had it working before my last reset. I accidentally killed my Contacts and Dialer. I can't Flashify/FlashFire LGContacts. 20/20 hindsight - I forgot to TB before messing with the Dialer/Contacts.
I am 100% willing to lose everything and start from scratch. If someone could help me get LGUP to work again I will be so grateful.
At least I didn't soft or hard brick it. . . . . . this time. (See my signature)

Does the LGH962AT use Tungkick's Rooting method?
If so, you could probably do an "Upgrade" while your phone is in Download Mode when rooting with the TOT file. That fixed a lot of issues I had on my phone and I didn't lose my important files, which by the way, I have to transfer to my SD Card.

First, I appreciate your reply . . . But . . . Tungkick uses LGUP, which my phone wouldn't connect to. The latest update to LGUP fixed that recognition problem that and I was able to fix my phone via LGUP.
I will see if I can change the title to SOLVED.

i had some issues with correct drivers. take autoprimes 10c or whatever his last was and reinstall lg up as the test dll file for 10i messes lg up quite a lot.
so I'd suggest cleaning your pc off everything related. and try following autoprime's refurbish process. as long as your device gets recognized it shouldn't be hard bricked.
You can try to use LG Bridge with V10i.
Follow the guide in this link:

I have got same problem. The phone is detected as firmware v10i so you must use dll modify trick from other post in kdz uprade section (there is proper dll file for upgrade to v10i). When you change dll from v10i firmware you choose upgrade (it is important to check option upgrade not refurbished, refurbished you can to after downgrade firmware to v10e) and I choose v10e then you can paste old dll and then you can choose option refurbished now. For me I have the same problem and it was related with dll files in pc and lgup and this procedure help me solve the problem.

Hi,
I was just wondering if you were able to revive your G5? I am in a similar situation. I was running ZV6 on my LS992 and decided to restore it to stock ZV6 but now it's dead, not even the display works(which is very weird). Following is the status of my phone, any help would be greatly appreciated:
1. Device has no display(it was working absolutely fine before I restored it to stock ZV6 firmware)
2. Device was not rooted and was running stock ZV6 before restoration attempt.
3. Even though there is no display, phone when connected to USB shows up as COM port, so I am assuming it is stuck in boot loop and even though I can't see, it goes straight to download mode.
4. LG UP Tool will no longer recognize the phone and detects it as Unknown and won't let me continue past the screen to flash.
5. LG Flash Tool, I think I am missing the LS992 DLL. I tried using DLL from UP tool which doesn't seems to work. H850 DLL doesn't work either.
I have read through the forum and information is mixed and nothing leads to anything helpful.
Flash Tool version: 2.0.1.6
Error: Failed (s)
I have all current drivers, LG Bridge and LAB framework installed.
I am honestly at the point where I want to buy Octopus box and get done with this. Lol.
Any help is greatly appreciated!!

Hello! I had this issue a while ago as well, I downloaded the LG Bridge program and used the software update tab to repair this problem! I had then caused the problem a second time and discovered that clicking "Software update" no longer had any effect on my device. I solved that problem by choosing "Update error recovery" it took a few trys plugging my phone in to have it recognize the phone but I later discovered that was my own fault.

Thanks for replying. I tried that but doesn't seem to work. Could you describe a little more in details on what happened? What baffles me most is no display. I also tried LG mobile support tool, it detects the phone and says software is up to date. When I try to use "Upgrade Recovery" option, it asks me for IMEI which I don't have. I tried a different IMEI for another LS992 and it keeps asking for model and serial no.
Any ideas guys? Still stuck with this thing. Do you think buying a fast charging cable type c- type c will help? I have a aftermarket A to C cable and I am really curious if that could be the reason.
Thanks!

If your looking to unlock H830, it's not yet supported. I think T-Mobile is the only one without direct unlock including H811. I simply love Verizon for this reason. Lol.
Let me know if you have any questions. I might sell this box to you since my goal is now established. Haha.

Cool thanks for the info. You can make pretty much make all your money back and then some. By repairing for people on ebay and other sites. You should keep it for that reason and future brick phones of yours.
I agree LG flash tool being garbage. I've seen others hard brick with that program. Some of even the soft bricks can be a pain in the butt to fix.
Yeah I might be interested if you still end up selling it. I just gotta save a few pay checks up first. Do you have a decent feedback account with ebay or Amazon?

Yep. I agree, it definitely is a very handy tool considering the amount of hrs I have spent since the LG G2 and Samsung Galaxy S2 days, I should have bought this long ago. Haha. I do have a good eBay account, we can pm.
I bought a H873 cheap, $120, off eBay on the last 7.0.
For whatever reason, OTA and LG Bridge couldn't connect to the network to update to 8.0 even though there wasn't any issue with my Win10 laptop on latest updates.
Finally found a working, easy solution to update the firmware anytime to the latest available when ota and lg bridge don't work.
0. Try LG Bridge first.
This is the Official way where you connect phone to PC, then officially update the firmware using LG consumer software.
https://www.lg.com/us/support/product-help/CT10000025-1438110404543-lg-backup-lg-switch
This also ensures you can see your phone when connected to the PC.
You'll want to click the pop-up notification on the LG G6 to switch the usb mode to file transfer mode instead of just charging.
1. Now, if that and OTA didn't work, you'll install Uppercut (a launcher for LG Up to enable compatibility with the G6 and other phones) + LG Up (their firmware flashing program not for consumers).
https://forum.xda-developers.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295
If LG Bridge is already installed and it sees your phone when connected, you don't need the LG USB drivers download. Otherwise, download this, uppercut and lg up (3 total).
2. Install lg drivers (if needed), then lg up.
Unzip uppercut anywhere, run it and it'll start lg up.
Connect phone (make sure usb mode is in file transfer mode) and it should show up in lg up.
Now disconnect the phone -.you've confirmed it'll show up, but will switch to download mode later.
3. Download the kdz (firmware) file of your choice.
https://lg-firmwares.com
There's a ton of places online for this, and I used this one. Just type in your model number, eg "h873", to look for one.
Now, you know the model number of the firmware MUST match (in general) your phone, so check (settings, general, about phone, hardware version). (Yes, there are other ways to cross flash, etc. See other threads).
For the H873, doesn't matter which carrier - rogers, etc - all identical. Otherwise, you'll generally want the same as your current one (e.g. T-Mobile firmware for T-Mobile phone).
4. Switch phone to download mode
Plug a USB cable into your computer (not into the LG G6 yet)
Power down the LG G6.
Press and hold the Volume Up button.
Connect the USB cable to the LG G6.
Continue holding the Volume Up button until it boots into Download Mode.
You'll see a black screen, download mode, box at the bottom for status.
5. Load the kdz in lg up by RUNNING UPPERCUT to start LG UP!
With phone connected, in file manager mode, and lg up running by starting Uppercut, you'll see the phone listed at top (it'll list the current firmware version on the phone - e.g. H87320h).
In the middle, select UPGRADE from the 4 Process options. This will upgrade your phone firmware like an ota, keeping everything.
In the bottom, click on the BIN FILE line once, then click the ... Icon that appears at the end of this line.
Select the kdz file you downloaded in step 3.
6. Make sure your computer is connected to AC and won't go to sleep (keep moving your mouse every minute, or adjust power settings).
Phone should be in download mode.
Click Start in LG Up and you'll see it sending files. The G6 will show progress as well.
Didn't time it, but quick - a few minutes and the new firmware will be loaded, then the phone will auto reboot to update.
...
The downloading and installing of uppercut etc takes a few minutes, kdz depends on server speed, and update just a few minutes, so not hard at all.
Really nothing major to worry about (backup naturally before any firmware update if needed to microsd card), and my H873 is running fine on the last Nov 2018 8.0.0 firmware.
Update: Now running on the latest H87320i_00_OPEN_CA_OP_0204.kdz released in March 3rd, 2019. Remember to do it in UPGRADE mode!
---
If needed, disconnect the phone from USB, press power button a few times quickly to get into Firmware Download mode - waiting. Then, volume down+power until the phone reboots into normal operation/mode.
Hello. It's very long time since I did my last modding operation. I need to re-install the current original firmware on my LG G6 (now I have a custom ROM). Can i use this procedure to do so? Another question: how could I check which firmware is installed on my phone? On lg-firmwares I see a lot of firmwares for Italy no carrier

6. Make sure your computer is connected to AC and won't go to sleep (keep moving your mouse every minute, or adjust power settings).
Phone should be in download mode.
Click Start in LG Up and you'll see it sending files. The G6 will show progress as well.
Didn't time it, but quick - a few minutes and the new firmware will be loaded, then the phone will auto reboot to update.
...
The downloading and installing of uppercut etc takes a few minutes, kdz depends on server speed, and update just a few minutes, so not hard at all.
Really nothing major to worry about (backup naturally before any firmware update if needed to microsd card), and my H873 is running fine on the last Nov 2018 8.0.0 firmware.
Update: Now running on the latest H87320i_00_OPEN_CA_OP_0204.kdz released in March 3rd, 2019. Remember to do it in UPGRADE mode!
---
If needed, disconnect the phone from USB, press power button a few times quickly to get into Firmware Download mode - waiting. Then, volume down+power until the phone reboots into normal operation/mode.

Hello. It's very long time since I did my last modding operation. I need to re-install the current original firmware on my LG G6 (now I have a custom ROM). Can i use this procedure to do so? Another question: how could I check which firmware is installed on my phone? On lg-firmwares I see a lot of firmwares for Italy no carrier

Ought to work since LG UP was designed to load firmwares into their phones. Naturally, can't say for sure since I've never done it myself (my model can't load cfm), so look at similar G7/G8 model threads on going back to the original.

On lg-firmwares, you can pick any firmware for your model to load.
E.g. If it's a uk model, and you pick an Italian firmware, that's fine. However the menus etc may then be optimized for Italian instead of British.
You can load any listed for your model from any carrier, too. Again, it'll have carrier specific optimizations, but otherwise work.
