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

I flashed my LG G3 Because i felt that the sound was not working anymore and that it can be a software issue which it was a hard ware issue ( loud speaker wasnt connected because of screw) Anyways preformed the stock FW Flash following the guide that highonandroid provided to go completely back to a stock rom. After flashing i restart phone and the boot takes forever until it finally hangs on the tmobile screen. there was a point where i left it over night to see if it will turn on but it still hung for a good 8 hours. Ive done everything i can which can be that i preformed atleast hundreds of hard resets but nothing is working.. there was a point where i did manage to turn it on then i tried updating to lolipop and when it reboots the bootloop is back.. Please help!
I assume you opened the back to fix the speaker issue. Did you make sure all connectors are tight?

Hi, i have the same problem on my international D855 variant, wondering if you found a solution as i have been stuck in a bootloop for the last 5 hours :crying: :crying:
thanks in advance for your help.
Use this method for returning to stock...

Same problem here, but here the device is G3 Liger F490L.
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.
So, some time ago I finally gave up on LG providing official nougat update for LG G4 so I decided to flash it and I found an official flash v29a, and everything went well.. except for my GPS. The GPS was not locking on and would take more than 100 seconds sometimes to lock on, I did not had this issue before so I decided to flash my device again hoping it would fix it, but it bricked my phone.
Now I can't reinstall or downgrade, since it would get stuck at 16% when flashing again and downgrade wont work at all. I get error 0x2000 "Invalid command Response". I have been trying to fix it for more than 6 hours now, downloading different KDZ's but it just won't work. I really need help here, I cannot afford a new phone right now. I have LG H818p version. And yes, I was using the correct version for upgrade/downgrade. I tried to hard reset it but it is still stuck on Firmware update. Urgent help is needed, since I don't have another phone to use and I really need this phone, been up all night trying to fix it..
Edit: Fixed it, don't know how tho
Hello, I would like to ask if my LG G3 is softbricked or hardbricked. It has been a long while since it decided to boot loop. I tried to fix it but got no results. I tried to factory reset it, but the next day it didn't turn on anymore and got stuck in the logo. Note : the phone was experiencing some heating issue before it decided to screw itself up. I tried numerous troubleshooting from the net, none worked. I also did try to reinstall the firmware to stock again, it did boot but it can't get to the home screen. I then factory reset it again and tried using another firmware also built for my phone (it's LG G3 D855). It failed again at 33% while it was in the firmware update mode. Now that I have left it for a solid year, I thought that it would be nice to try again. Which I did, but it couldn't charge anymore and it cannot boot to the logo. I tried to go to the download mode but no response. I tried connecting it to my computer, but it only detects my phone as a charge only device, it also detects it on only several random occasion. I hope this is a softbrick and it can be fixed at home so I don't need to go to the store to repair it.
I'm sorry for the long explanation, I had been trying to revive it for months now and had no luck. How do I fix this, at least how do I get to the firmware update download mode again? I really really hope that anyone can help. Thankyou so much in advance.
