So Long Story,
Monday November 24, I Changed Out Battery Go To Restart Phone, Phone Wont Boot Stuck On LG Screens And Constantly Retrying. Tuesday Night November 25, I ReInstall Factory Firmware For G3 D852 – With Success – Phone Working. Wednesday November 26, I Decide To Root & Install TWRP – With Success – Phone Working No Issues. Friday November 28, This Is Where Sh*t Hits The Fan! I Get Crazy & Attempt To Install ChupaChups Lollipop Rom With TWRP – Seemingly Successful Install But After Reboot Wont Boot Stuck In Fast Boot. So I Attempt To Resolve This Following Other Forum Posts Using FastBootOV – WITHOUT Success – Now When Attempting To Boot Phone LG Screen Comes Up Top Left Corner Says “ERROR Boot Certification Verify” Below That Says “590 Secure Booting ERROR!” Then Black Screen With Flashing Red & Blue LED. I Attempted To ReInstall Factory Firmware For D852 With LG Flashtool Attempt Fails Stating Wrong Model Number – Phone States On Screen Near Bottom Now D855 Ver5.0 Below That D85520A.
Finally Success With Phone December 28, After Countless Hours Trying to Find Some Shred Of Info To Resolve This Including Posting Here For Help Without A Response. I Proceed To Attempt To Reinstall Factory Firmware For D852 - Failed Same Result Wrong Model Number D855. Actual Model D852. I Then Decided F**K It Ill Install D855 Factory 32G Firmware UK Version Why Not? At This Point Phones A Paper Weight In This Time Had To Purchase Another Phone (So I Dont Lose My Mind) - All Available Information Points To Send In For Warranty. So I Do So Again Attempting To Install The D855 UK Firmware Failed To Install Using LG FlashTool, This Time Stating Partition Errors. So I Find After Random Searching & Random Reading Of Everything LG G3. I Find A Generic LG G3 DLL File (LGUP_8974.DLL). Using The Generic LG G3 DLL & Factory Firmware D852 With LG FlashTool - This Time Working Up To 89%, Phone Reboots Shows Large 2, Crossing My Fingers Waiting For The Large 3. What Actually Pops Up Is A Large 0. I Attempt To Reboot Phone Goes To Mini OS, Set Phone To Reboot Normally - AND SUCCESS!!!!!! Factory OS Boots Up, The Usual YADAYADA Setup.
So Thats All, A Long Winded Story BUT Now There Seems To A Cure To Flashing WRONG Model G3 Roms To Your Device.
Hope This Works For Everyone - I Have Devoted Coutless Hours Trying to Avoid Sending My Phone In.
Good Luck!!

Man, this was a long story but I am so glad you have posted this. I always wondered what would happen if I by mistake flash the wrong file (diff model), and now I know. Can you please send me the link to the info and the files, just in case I end up where you were (email: elmspace at gmail dot com), I would appreciate it.
Thanks man. I was just wondering what is going to happen to my LG g3 D856 variant if i flash D855 kdz. Now um not gonna do that. Let's not flash any rom. I successfully rooted and am using D858HK twrp ( yeah D858HK) successfully.
hi hi
hi hi same problem after i want to root the phone my LG G3 D852 my phone stuck on fastboot mode blackscreen ,my pc see it like Android bootloader Interface BUT no other programs see it try lg flash tool or lg repair tool or cmd command nothing they don't see my G3 HELP HELP PLEASE
Sorry for the no response on this problem , got the same problem last year by flashing the d850 rom to a d852 model but this solution is not recommended. It works sometimes (was working with mine but I bring it to LG because the motherboard dies for no reason after one month of use lol) but the installation can go wrong and destroy your motherboard.

Holy hell I ran into the same issue and spent countless hours getting my D852 back to life after flashing the wrong ROM. I found this and sure enough it came back!
plss help

Hey!
I guess i just softbricked my phone, by installing a D855 firmware thing, using LGUP, and don't know how to fix this. To be correct, it turns on to the LG logo, and stays there forever. I can use hard reset, and it does the job, but still bootloop thing. I can also get into download mode, but nowhere further than the LG logo screen if i just turn it on or something. Tried to use LG Flash Tool on multiple computers one after another. I followed guides for help with it, and did everything as they described, but the problem with this, is after i use LG Flash Tool with the correct .TOT file, and .DLL file, it will just say "Model Information Chech FAIL.", so i can't fix it by flashing the correct files. I've been trying everything for 2 days, but no luck. Please, can you guys help me? :'( I'm worried.
Update: My phone is now fixed. I don't know how it got fixed. My brother did it, and he doesn't tell me how he did it. :'D Anyways. It's now fixed, so thank you for everyone who messaged me about this with helps. ^^ After 2 days of trying, its finally fixed.
Hi all, I've had some issues with my G3 and have got to the point where I need the advice of wiser heads to try and fix the problem!
The phone seemingly died during an update a few weeks ago, but I was able to fix it using LG's tool and upgrading to Marshmallow. Then a few days ago with no warning the phone froze, and gets stuck in a bootloop at the LG screen, with the flashing LED. If I try to factory reset, I just end up with the Android Droid with a red triangle and I can't get any further. I've tried numerous guides I've found to try and reinstall the stock firmware, all without success. (I haven't tried accessing bootloader as I have download mode available). LG's own tool gets stuck at 4% when I try to recover, and I've tried the LG Flash Tool but get an error at 6% (LAF_READ_GPT_FAILED) using the 8974 dll. I've also tried the LGUP tool but that gets stuck at 6% (Error can't communicate with phone[Kilo Packet]. The phone was not rooted and is a 16GB UK version (model D855). I just seem to be going in circles now trying to find a solution, I suspect somewhere along the line I'm using the wrong combination of programs/TOT/DLL files so I could really do with someone pointing me in the right direction here!
Hey, my Lg G4 H815 is dead. It got a bootloop at the logo. I only one got it to the startscreen but it died again.
I tried every thread offered I found. I ended up with going into download mode and install back to stock. This didnt work with lg flashtool so I tried the method with lgup. Nothings changed. What now happens is that when trying to get into download mode, it says some seconds donload mode and swithes back to the logo. Since then I dont even get into hard reset mode.... So can I through it into my trash can? Or does anyone know how to fix this? I would be thankful for every answer.... have a nice weekend you all
as long as the phone is for your region LG should repair/replace it. I just had the same issue with my H811 and despite it being 1 year and 2 months old they repaired it free of charge.
Hello everybody! I have a problem with my phone(LG G3 beat D722p), well, my phone is stuck on startup/logo screen. When turn on my phone appears LG logo and then appear the logo of my company and here is where my phone is stuck.

I could do a hard reset but if I do that I will lost all my data (and is very important). I need help please! I need recover all that information.
Mmm download mode maybe?
