LG | Cross Firmware Flashing/Downgrading | Error 1002 | 4% Update Fail FIX - LG Optimus L9 P760, P765, P768, P769

This post may be helpful for:​
1. People that are trying to downgrade from firmware they flashed.
2. People who accidentally flashed wrong firmware and now they want to flash the correct one.
3. People who generally want to flash a firmware using the KDZ Updater, ​
AND
Cannot do the things above because the KDZ Update tool shows the "Error 1002" or the update tool stops at 4%.
P.S. 1: I have tried that on Optimus L5 and L9 when I had same problem and it works. Some users also told me it works on L7 too.
P.S. 2: I don't know if it will work for EVERY phone, I'm just saying it worked on mine. Maybe I'm lucky! But if you tried everything and nothing worked, maybe you could also give this a try.
P.S. 3. YOU MUST HAVE A WORKING FIRMWARE(a firmware that can get installed-doesn't matter if it's the right one).
​
Solution
First time I did this was with an Optimus L5 - E615.
In my case,there was only one firmware that worked and got installed with the KDZ Updater tool.(The v20b-for L5 E610 - Europe) which was not for my model and I flashed accidentally. Nothing else worked, no matter which firmwares (From LG site) i tried, compatible or not.
I only managed to fix that when I downloaded the firmware i wanted to install, and "tricked" the PC into, thinking that it installed the 20b.
I don't know if that issue happened only to me only, but IF someone has the same problem another time, it will maybe work for him too. Or maybe it will be possible solution to everyone flashing a wrong Firmware..!
The thing is , I noticed that the KDZ Updater, everytime it wanted to install a KDZ, it extracted it as a .DZ file at the "LGMOBILEAX" folder located in C/appdata folder.
In L9 it's .WDB instead of .DZ files. So I'm changing it to WDB for the solution
To fix the "Lparam 1002 Error"(Stop on 4% of update tool or crash error in KDZ updater ) do the following steps:
1. Install correct drivers from LG mobile tool to be sure my phone was recognized.
2. Move battery out(Optional, by I prefer it if it's possible).
3. Enter Emergency Download Mode(By pressing the Volume-Down button while connecting the phone with the PC).
4. Extract the -workingfirmware.kdz and the firmwareyouwant.kdz with the Rom Converter Tool made by jes0411 (Original Post HERE), and rename the extracted firmwareyouwant.wdb same as workingfirmware.wdb
5. Start the KDZ update, choosing the workingfirmware.kdz, and when the workingfirmware.wdb file is extracted, replace it immediately with the (now renamed as "workingfirmware.dz") firmwareyouwant.dz
EDIT: If you are too scared of replacing files during the procedure, just wait until the update stops and asks you to restart. You can replace them then.
Wierd issue from LG, but it worked for me!
Cheers.

Thank You!! It works!
I can confim it works with LG L7 (P700/P705) too.

L9 does not have any file extracted with e610v20.dz name or any file with .DZ extension. Are you sure this is somewhere related to L9 by any chance?

Check P.S.1 and what I wrote below mate
Every LG firmware (.kdz files) is extracted as a .dz file during Firmware installation via LG update tool or KDZ updater.
About the e615 files, it's because I had this issue on a friend's L5-E615, but I'm also posting here because I've tested this on L9 too and it's working if you have this issue. From pms and posts I got, it seems that this works on most lg devices(L3,L5,L7,L9). I just posted here because I own a P760.. I'm just trying to contribute to the L9 community..!
EDIT: Cmahendra was right, the file extensions in L9 is .wdb. My bad, nevertheless the solution is the same...!
Cheers,

(NOTE: This thread is only for NOOBS like me and for Junior Members.)
ATTENTION: THIS WORKS ON ICS/JELLYBEAN with both locked/unlocked bootloader.
But Go here for FASTER Root L9 JB/ICS on Unlocked Bootloader.
To understand and perform Flashing L9, you should read all following threads carefully before starting.
GUIDE TO NEW ROOT L9 WITH LELUS METHOD AND FLASH L9 (this post)
LELUS THREAD to Root L9 Thanks to Lelus (GUIDEPOST BY ARTIT Thanks to Artit for his preliminary guide)
JELLY BEAN ROOTING FILES BY ANGRYWOLF80's
TUTORIAL ON OFFLINE FIX FLASH METHOD by me << VERY IMPORTANT HERE
COLLECTION OF READY-MADE HEX-EDITED BIN FILES (in second post) by me. BIN files ready to download and flash. Now includes Jelly Bean files too.
MAKE YOUR OWN HEX-EDITED BIN FILE EASILY again by me
If anyone want to learn and still want to make their own HEX EDITED BIN files from their own KDZ, its really very easy. You dont have to download huge files again, and will be able to make your own edited BIN from the KDZ you already downloaded before. To support Rooting L9 with Lelus Method, I am uploading and collecting the readily HEX-EDITED BIN files. Now you dont have to worry for Bricking with wrongly EDITED BIN file. This will AVOID the process of editing HEX file, which may be bit confusing for some noobs like me
============================
SPECIAL THANKS TO LELUS AND ANGRYWOLF80 FOR THEIR TEAM WORK.
LELUS: This Rooting Method is not my original work AND ALL CREDIT GOES TO LELUS WHO GAVE THIS NEW CONCEPT OF HEX-EDITING OF BIN AND A SH SCRIPT TO RUN BEFORE FLASH. Without Lelus this thread might not exist.
ANGRYWOLF80: I am really thankful to him for providing a solution with changes in Lelus's script so the SU is not copied on every boot and also made changes to avoid mounting system in RW mode, keeping original hdcp.sh file without changes. The current improved modified BatchFile is by him. This removes some vulnerabilities.
Also thanks to him for JELLYBEAN ROOTING FILES. Pals, he really worked hard for this. Press THANKS button on his thread.
Adixtra and Unknown_world : Makers of Offline Fix Flashing Method. Without them Flashing Guide was not possible.
GUIDEBOOK STEPS
=============
0) Precautions:
___A) Select "Debugging Mode" as ON (Ticked) in Phone Settings (Developer Section)
___B) Select "Install from Unknown Sources" as ON (Ticked) in Phone Settings (Security Section)
___C) Indian version of L9 does not come with "Lookout Security Antivirus" already installed. But KDZ from other countries may have it already installed, FORCE CLOSE AND UNINSTALL it from app manager. If you cannot uninstall, at least DISABLE it. This program is known to be preventing connection and rooting of device.
___D)OFFLINE KDZ FLASHING DOES NOT LOOSE PHONE DATA, BUT YOU MUST BACKUP YOUR PHONE IN ANY CASE.
1) Download Hex-Edited BIN file and related KDZ file (on same line) in exact combination shown in SECOD POST BELOW. If you already have downloaded exact KDZ from this post, then you dont need to download KDZ again, just download matching BIN file.
2)
FOR ICS Download >>> Root_and_Flash_Guide_byCMahendra(date).zip
FOR JellyBean Download >>> RootJB_and_Flash_Guide_byCMahendra_AngryWolf80(31-Mar).zip
Either choose ICS version or JB and extract in your C-Drive.
Now you will get three folders named "C:\RootLelus" and "C:\RootFlash" and "C:\shttps"
3) Install Drivers: "LG USB Driver (Download 3.8.1 here)"
4) Optional if installed before: Install MSXML 4.0 SP3 Parser by running "msxml.msi" file in "RootFlash" folder.
5) Connect Phone to PC with USB in "MTP" mode, let all drivers install for detected hardware items, then in "Charge Only" Mode, let all drivers install, then in "PTP" mode and let all drivers install, LASTLY connect in "LG SOFTWARE" Mode and let all drivers install. Don't neglect anything, it will save OUR time.
IMPORTANT: Weirdly windows will try to install its own WDM drivers searching online in internet. Do not let it install like that. It will be stuck with longer time or it will just fail to install drivers.
Solution: Always Click the link/button "Skip Obtaining Driver....." shown in this screenshot, so pc will install only original LG drivers for all devices in all usb modes.
6) Keep phone in "LG SOFTWARE" Mode and wait until it is connected. Now at this moment Device Manager should show 3 entries like this. If not, flashing will not work. (This is Important Checklist Step)
7) ADB MODE: Now start Windows Command Prompt with "Run As Administrator" option. Try to ping any website, if you SEE THIS DOS ERROR (SCREENSHOT) you are not in Admin mode and you need to try again. (THIS IS IMPORTANT CHECKLIST)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now pass following commands in lower case as adb command is "case sensitive"
C:\>CD \RootLelus
C:\RootLelus>stuff\adb devices
Click to expand...
Click to collapse
***For Jellybean the folder will be "RootLelusJB" instead of "RootLelus"
Now your device should be shown as "List of Attached Devices" like this result in screenshot. (Important Checklist Step)
This means your device is ready to take ADB Commands. PLZ DONT IGNORE THIS CHECKLIST. If fails, check cables, reinstall drivers, restart pc, connect cable directly on motherboard USB port and try again from first step.
8) This is important root preparation for Rooting before Flashing. Now Run a batch file "RootL9" on command prompt with following commands.
C:\RootLelus>RootL9
Click to expand...
Click to collapse
This simple automated command batch-file (RootL9.bat) will copy necessary files to special locations and will set some necessary permissions.
When done, REMOVE USB CABLE AND POWER OFF THE PHONE.
9) NOW ACTUAL KDZ FLASHING STARTS AND THEN A QUICK MAGIC TRICK IS TO BE PERFORMED.
___9A) Add lines in "hosts" file as mentioned in step 1 of this post.
___9B) Start "SmallServer" as mentioned in step 2 of same post
10) Now follow all steps from all 3 to 10 from this original flashing post. In 11th of original flashing post your have to do following magic.
11) ACTUAL MAGIC:
After LG UPDATE TOOL starts, wait for following message in RED SENTENCE.
When you see this message and update meter reaches to 8%, then
quickly open this folder "C:\ProgramData\LGMOBILEAX\Phone"
and look for extracted bin files, if you see the same name as BIN file you downloded (LGP765_AP[6].bin or LGP765_AP[11].bin), replace it with the one you downloaded earlier (which is already HEX-EDITED).
Press "Continue" if windows asks you for permission to copy and replace.
Folder not found? Workaround: Copy this "C:\ProgramData\LGMOBILEAX\Phone" and paste in windows explorer at top, the folder should open directly, then replace file. In one of the rarest case, in WIN XP machine the folder was found here "C:\Documents and Settings\All Users\Application Data\LGMOBILEAX\Phone" in this post.
Still problems? Check this post too.
Let flashing complete, and you are done. YOU HAVE JUST ROOTED L9!!! Phone should now reboot with working SuperUser. If SuperUser ForceCloses, just restart phone once again.
12) CWM Recovery Installation on ICS: This rooting does not install ClockWorkMod. First run SuperSU and install SUBinary if it asks to install and then visit this thread to install L9 Recovery Installer by Artas182x. First install this app and then run app and install Recovery.
CWM Recovery Installation on Jelly Bean: Please follow AngryWolf80's thread for installing CWM. If you dont find the information, post your question in his thread.
13) BUSYBOX Re-Installation: According AngryWolf80, he found some new vulnerabilities and recommended to uninstall BUSYBOX and REINSTALL it as per this thread and these instructions. Though this is applicable to the Root File released on 6th March, but these instructions by AngryWolf80, can be tried by anyone just to install and update busybox.
========================================
Troubleshooting
1) After step 2: If extracted folders need any permissions, then you should provide in folder security section by adding user "everyone" or "<yourname>" and give full access. (example video) This is Optional and should be done if you have permission errors while flashing. Do it for all three folders.
2) About 11th Step: The most common problem is you may not be able to replace the file in LG folder in quick time. You have to be very quick, so the FOLDER should be open in advance. You can even open the folder in the beginning and minimize until it is required to replace. If you are late, the LG TOOL will flash original file and root will fail. Or you can open the folder immediately when it starts at 4% and keep looking for file to replace. As soon as you see 7th BIN file PASTE it with 6th BIN, you already COPY'ed before.

I checked this link and searched the link inside but did not find any link mentioned by you for Hex-Edited V10GP769 bin file. Please recheck and send exact link or post with link.
When I posted that I didn't have 10 posts yet, so I couldn't post an actual link. Instead, I replaced "." with "[dot]". Anyways, I've just uploaded it to multiupload.nl for you. I've rooted with this on my own P769 and have checked the new checksum with the old one to ensure it hasn't been corrupted since the file was last accessed.

When I posted that I didn't have 10 posts yet, so I couldn't post an actual link. Instead, I replaced "." with "[dot]". Anyways, I've just uploaded it to multiupload.nl for you. I've rooted with this on my own P769 and have checked the new checksum with the old one to ensure it hasn't been corrupted since the file was last accessed.
Update:
Just uploaded the unrooted KDZ for P769BK V10G TMO USA (MD5: f467e9a0d0d4c3880486384b12fb081e), which I originally found in this thread, to multiupload.nl before realizing someone else already did. The official link for the KDZ gives you an HTTP Forbidden (perhaps the LG Upgrade software uses a special user agent, or contains other header info).
You can be sure this is the official and correct URL because they're structured as such: http://csmg.lgmobile.com:9002/swdata/WDLSW/model/authentication/rom/rom.kdz. Everything that's been italicized is changed. You replace it with info from this URL: http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI where IMEI is your IMEI number. The page will give you some information about your phone. Shown on the page, you'll see your IMEI. After that number, you will see your model, the authentication, a number-letter combination I'm unsure of, and then the release date of your phone. Anyways, replace model and authentication appropriately. The name of the rom isn't on that page, but you probably already know the name of the ROM you're looking for anyway. For example, V10g_00. I know all of this from bricking the Optimus S, unbricking it (in fact, I did this several times), and posting a guide over at androidcentral (under a different username).

I didn't use the rom linker because I was detecting spyware from it with several databases. If it used easy-to-read client-side JavaScript rather than server-side ASP or if it came from a website registered by LG, then I'd feel much better about using it. Besides that, I think it benefits everyone to know how stuff works, rather than relying on a tool.
Sent from my LG-P769 using xda app-developers app
EDIT: LG update will not run because it says "Please install CSMG B2C Client Tool" "Select tool ->B2C Client setup menu"
I tried that as well as manually downloading the b2c installer however it does not change anything. Ive also tried compatability mode (win xp sp3) and that didnt help.

I was Searching For The .dll File For Our Device And Found It So Decided To Create A Thread.And Those Who Are Thinking That The Required .dll Is The Same That We Use For LGNPST,NO,This Is A Different .dll
It Did Not Ask For Unlock Code When I Flashed The Stock JB FW.But As Posted By madmack there is A Possibility That It Can Ask For Your Unlock Code.So Proceed With Caution.
Again This Is A Alternate To LGNPST And Only I Have Successfully Flashed The Stock FW.It Is Recommended That Unless It Is Tested By 4-5 Experienced Users,Its A No Go For Noobs/New Users.
And Be Advised That This Process Will Wipe Your Internal Storage.
Enjoy!

Thanks for sharing.
Edit: There are many more things to do in his (madmack) thread... Did u follow them all? Or for us we do not need all those steps? Let us know before someone bricks.. I use LGNPST but if anyone tries this.. at least they have a better understanding. thanks again for sharing.
just a heads up.. TeenyBin does not work in LG Flash. There are extra CRC checks which I haven't been able to bypass yet. This may change in the future.
also, not sure if this version of LG Flash is same as the newer one I use but I have to set the COM port to 40+ for LG flash to see my device.. altho maybe I'm missing something. I have to go into windows device manager and manually change the COM port used for the phone ( its in properties ).
LG Flash is no better or worse than LGNPST in my opinion. On the plus side.. there's no dll to register... and options are good

Download link is missing.
I've try to found the download link for the Lg Flash tool on this page, but i haven't. Can you fix it or explain? Thanks anyway.
Which .TOT and .DLL files will you be providing? I need the .DLL and .TOT file for, of course, the AT&T Optimus G E-970 US version! I flashed my wifes phone cause it boot looped and the .TOT used was SUPPOSED to be this file but it is the Korean FW. Now my wifes phone will not update via OTA because it changed her IMEI number. I need to get her phone back to stock 4.1.2 US VERSION!

Here is the file you need to get her phone back to STOCK U.S: http://downloads.codefi.re/g33k3r/LGE970AT-01-V20j-310-410-MAR-08-2013.zip I'm not sure on the DLL file, I use LGNPST so not sure if they are the same but attached it also just incase you can use it.. stock firmware file above is a .tot file so if you need to you can just change it to .bin if you need to.
Thank you blake but no. That is the fw file that turned her phone Korean. So may people are under the impression this is the stock US fw but it isn't. I even had another person here check their phone and his too in fact says "Lg Electronics Korea".

Where do you go check to see if its U.S or Korean?
All settings--> about phone -->phone Identity.
It's under settings-->about phone-->phone identity.
I had another person tell me that's normal because it's only the "manufacturer" info. Which im told this phone is manufactured in Korea. I don't know. All I do know is everyone is saying this is the stock fw for this phone but my wifes phone has changed. The start up screen is different and so is the shut down screen. Example, when her phone would shut down, she would get the AT&T logo and sound. After flashing this file she gets the blue circle and no sound. I do know that 4.1.2 is different depending on the region the phone is in. I don't know anything else that would explain this. Maybe this FW file WAS a different region but it was stripped out and converted somehow?

After a little checking I found out the same thing, It was normal as it was the place of manufacturer. I'm not sure what the problem might be but as far as I know that's the stock firmware for the phone.. You might try this one out http://www.androidfilehost.com/?fid=22901594685177912 you just boot into recovery do the normal wipes and flash through recovery, its supposed to be stock except for being rooted and as far as I know those are the only two stock files floating around for the phone...
Thanks Blake. Can you confirm for me that this phone will NOT get OTA updates if it's changed in any way, including rooting? It's what I was told by someone else. If that's the case then I guess there really is nothing wrong with the phone except those weird unexplained small changes.
I've got all the correct files download and I made it so far as to try to actually flash the phone, but it fails and gives me a wrong model number message because it's detecting my phone as a E960 (it's an E970). Any ideas? I had installed the latest CM11 ROM over some encrypted data and now I'm locked out (old encryption PIN doesn't work) and I can't restore it to stock.
can someone help me with a .tot or .bin stock for lg l70 d320n? cuz i"ve looked for it everywhere but couldn"t find anything
need help bad.
i got this phone from a friend and it originally had cm11 on it. the phone in question is the lg e970. i wanted to get back to stock. so i downloaded the correct firmware and added it to my external sd card. using twrp before i proceeded to wipe the phone via twrp. when it was finished i restarted the phone into twrp and went to install the stock firmware and i could not find my exsd card. twrp does not recognize it at all. so now im stuck with a phone with no os on it. i can ge into twrp and download mode, and when i just boot the phone it goes to lg logo and stays there. i need help in trying to figure out how to get stock firmware back on phone. i am used to samsung phones and odin. so im a noob when it comes to lg. i am very tech savy when it comes to computers. plzzzzzz any help would be great!!!!!!!! and appreciated

Now I'm trying to unbrick it with this tutorial but I can't find the .tot file for the D802.
http://optimusforums.com/threads/guide-complete-guide-to-unbrick-your-soft-bricked-g2-f320.9232/
The thing is, I have extracted the .kdz and it outputs a .dz and a .dll when I'm trying to start the flash progress, there is a popup wich says "Failed PriviousLoad()... :/
Could someone please help me out?

hi i have LG G2 D802 16gb
last week i flashed kitkat rom, but since most of G2 specific apps are lost, i didnot like it and i want to get back to stock.
i get "stuck at %49 error", "page error", "wparam error", ("whatever you call error") all the time while trying to flash d802 stock rom with "R&D tool", i tried on Win8, WinXP..
I changed the USB com port to 4, to 41.. nothing Worked!!!
and at last!..
I ve found a solution...
here it is...
i found the python script, called "KDZFileTools.py" written by someone (called thecubed) in this forum.
thanks him alot!!! and here is the link;
http://forum.xda-developers.com/showthread.php?t=2483250
to make python script file run in Windows go to http://www.python.org and download python 2.7 (NOT 3.x) and install it..
then put .py script file, .kdz file into "c:\python27\" folder (this folder is created default when you install python)
and in command promt type;
python KDZFileTools.py -f D80210B_00.kdz -x
this commands extracts the required .DLL file from .KDZ file, to "c:\python27\kdzextracted" folder, the extracted.dz file is NOT necessary for this tutorial.
and i found a tot file from this link, http://downloads.codefi.re/autoprime/LG/LG_G2/D802/Stock_Firmware

i used these two files (DLL i extracted from kdz and tot file) with LG Flashtool v.1.5, you can find it here:

.tot file for D80210e_EUR_XX
Are any of .tot files from link above compatible with phone running stock d80210e_eur_xx, so 32Gb version? Or can I just use the one which is for 32Gb version (using .dll from d80210e_eur_xx.kdz and .tot from d80210b_sea_xx) and then use .kdz method with d80210e_eur_xx.kdz to get my carriers official ROM? Thank you in advance!
Worked perfectly

Thanks man, I had some problems with the LG UpTestEX software, and your method worked perfectly !
I made a successful downgrade with a D802 (4.4.2 Vodaphone to 4.2.2 JDQ39B) :victory:
When all else failed... this worked.
With correct dll and tot files... this worked a treat.
Thanks for all the work guys

It was a "bit" long time ago I dont remember exactly what the issue really was. But i think "memory variant" wouldnot be important for dll.. give it a try, it should work..

Thanks for the reply. So should i extract the DLL from the stock KDZ and the flash the 32gb TOT from that link? Are you sure it won't mess things up more?
I badly want to fix this issue or else i would have to pay a hefty amount to my friend. I just want to be sure i dont render it completely dead.
By the way, are those TOTs carrier specific?

VS990 (Verizon V10) 11B Full KDZ, LGUP & Working DLL Download

Hello Verizon V10 Community,
I was able to locate the full KDZ file for the Verizon V10 software version 11B, the latest available for the VS990. I personally have the V10 and it's already on 11B but I have a friend who just received his V10 in the mail today and it had 10B on it so I plugged his into my computer and the Verizon Upgrade Assistant downloaded the 11B KDZ. I have saved it, uploaded it and am making it available anyone who may need it.
You can download it from Android File Host here in a RAR archive: https://www.androidfilehost.com/?fid=24438995911975083
Alternatively, you can download it directly from LG's servers here: http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FW25NOE3325BACQF4BA4K6T/VS99011B_04_ARB00.kdz
MD5 of KDZ file when downloaded from AFH (NOT the rar file): 7f971f72b81945ad1f06df56300b6bae
You will need to use LGUP to flash this KDZ, which you can download from here: https://www.androidfilehost.com/?fid=24459283995297690. After you have installed LGUP, you will need to extract the 'common' folder from the LGUP rar archive and put it in: C:\Program Files (x86)\LG Electronics\LGUP\model. (See attached screenshot) This 'common' folder contains the DLL file that is needed for LGUP to recognize the Verizon variant of the V10. There are other downloads of LGUP in other forums here in XDA which contain other installers in addition to the LGUP installer. The other installers install DLL files for other variants of the V10 which are not needed for the Verizon variant. The DLL I've included in the 'common' folder is all you need for our Verizon variant.
Enjoy
Reserved
And reserved again.
How big is the file size?

The KDZ by itself is 2.2 GB. I'll have the link ready later today as my FTP upload to AFH that I had running this morning failed and I have to start over. :-\
Thank you brother downloading now.

I've not yet tried flashing this KDZ but I'm going to assume we can use the LGFlashTool to flash this as the cool new LGUP program that has appeared recently in the G4 forums does not work with the V10. I tried it and the program won't even open when my V10 is attached to my computer. I'm guessing it needs a DLL file installed to work. If anyone knows where I can find one, please let me know.
I assure you this is not a fake. This is a genuine KDZ file downloaded directly from Verizon Upgrade Assistant. If anyone here decides to flash it, please let me know what program you used and the outcome of the process.

Same process I posted back in Jan about getting the .KDZ and the post to go along with it. I was unable to get the .KDZ file to flash to the phone. The version also had much userdata included in the file which is why I never released the file.
http://forum.xda-developers.com/showthread.php?p=64828296
This thread claims to have the .KDZ file directly from the LG site.

I'm not sure what version I tried but I had many different versions of the software but didn't want to run into a bricked phone and didn't have much time to spend on trying and failing with personal things going on.
LGUP isn't recognizing the KDZ file. It sees the TOT however. Any way to fix this?
EDIT: Just had to choose the Update radial instead of Refurbish.
I believe upgrade is tot only and refurbish is kdz and tot. Or vice versa.
We just got our upgrade to marshmallow is going to be possible to obtain root for it?
http://www.verizonwireless.com/support/lg-v10-update/
Just going to throw this out there. No matter what KDZ file I download, I can't get passed the Google Account setup. There's data on that file that prevents the phone from going forward and constantly loops back to the beginning of entering the Google Account previously associated with the phone before the factory reset.

Lg v1o bootloop
Hi guys, I'm James and I live in mexico. I'm Argentinean. A month ago I bought the LG V10 and then use it normally, one day I restarted the phone all the time and now stays at the logo screen. I know it is operational, the software system. But I took my phone to a technician famous city where I live repair and told me not found support for the cellular putting on new software. You think you can help me? Please . If necessary I will do it myself. What I find something silly and illogical is that he has not found support for the LG V10. Sorry for my English if there are errors. Thank you.

H960A stuck in Splash-screen

Hello,
Today I tried to Root my V10 using this method: http://forum.xda-developers.com/lg-v10/general/root-h960a-tot-add-systemrooted-t3337706
and now it gets stuck while booting. Is there a way to reflash the Original Firmware? (and keep my files)
I tried the "update error Recovery"-Feature in LG Bridge but the download goes really slow and I don't know if it can help me at all.
I hope someone can help me here
~Dekkia
Hi,
you should try to flash the appropriate KDZ file with LGUP. There is also the possibility to upgrade the phone and keep the data. You'll find the KDZ file and the link to LGUP (including description how to flash) in the first post of this thread: http://forum.xda-developers.com/lg-v10/general/kdz-download-lollipop-kdz-10c-lg-servers-t3332348.
Make sure you select the correct KDZ file depending on the version of your phone (H960A for Europe or Middle East).
