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 think i bricked my D855.
I was on Lam Hoang 1.8 rom, but i wanted to restore the original firmware v20h.
I've done the same thing i did many times, i tried to use kdz tools to flash the stock rom.
Everything was working fine when i got stuck at 10% in S/W Updating process.
I unplugged my phone after about 30 minutes, then i tried again, with the same result.
So i tried the TOT method, but the problem is the same, stuck at 10%.
It seems to be stuck on modem installation, as the last line in the log is MODEM.
Does anyone know how to fix this?
Thank you.
Resolved.
It was my pc fault.
I'm sorry.
Hello everyone. I am new to Android ROM custom upgrades. Its been around three weeks since I've experimented with my LG G3 D85010F and I would highly appreciate it if I find a useful answer to my query. I wanted to upgrade to Marshmallow so I tried using a CM 13 custom ROM and TWRP. I however ended up hard-bricking my device so I used the BoardDiag tool and I was able to get it out of the hard-bricked situation and then I used the LGFlashTool to flash the TOT file (D85010D, because i could not find the D85010F file) but the phone gets stuck in a bootloop(No Mini OS and FBOOT check ends in failure). I tried flashing the LGD850PR kdz file and the same thing happened. So I reverted back to the D85010D and still the same bootloop. (In case this is relevant I had charged the battery to around 90% before doing the flashing). Now I'm out of ideas and I could not find any solution online. What could be the problem? Thanks in advance folks!!!
Hello, so basically today out of nowhere, i found my lg g3 bootlooping (Lg logo+led blinking) and nothing else, tried hard reset, but got a android on the ground with red triangle, then got to download mode and tried everything that i could find to get it working, but nothing worked.. LG flash tool with dll and tot, other tool with .kdz, but everything fails... i think it might be that im trying not the stock firmware.. I tried all europeans, international versions, with no luck. got the .kdz method getting up to 99% and then the flash tool crashed, and on the phone same bootloop. found my stock firmware by IMEI, but can't download it:
6PL/PLUS_16G(POLAN V30b LGD855
The link for me isn't working:
csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FW299GH752SMAA174B8C7JP/D85530b_00_0927.kdz
I'm literally out of ideas.
i have no warrienty. :/
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
