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

5.1 update for o2 UK is now live
5.1 or 5.1.1?
Normaly 5.1 ....
Version 5.1 is currently in deployment in EMEA.
5. 1
Hurriedly typed the title.. Woops ?
Its 5.1, takes about an hour (5mins to download the rest to update) and put it somewhere cold as it gets rather warm to the touch..
Otherwise the update was successful. Do not touch the phone as it will reboot several times and appear to be stuck in a boot loop but it isn't!.

Hi
am having a very strange problem with my phone, first it was the sim not working, until I continuously remove an install it again and again,
it was first runing on android 5.0 fully OTA updated.
However in a try to resolve the problem, I connected it to LG pc suite in order to get the android 6 ! it was working for a day, but it suddendly it stopped and went OFF for ever.
Thanks to a thread here in the forum, I Hard bricked it then soft bricked it with kitkat 4.4, it worked without any problem, but when the auto updates went to lolipop 5, it stopped again.
I installed marshmallow 6 with flashtool, the phone is working with the SIM without Internet with no problem, but, when I connect it to the net, and specially when I enter my gmail account it goes to the same loop again, and I have to flash it to return back.
Please Help.
Check which version of gapps your using... That's the only thing I can think of
Hi,
I was using my G4 H815 SEA version last night when it suddenly rebooted, it's been running 20j with Genesys mods for Bootloader locked devices for about 6 weeks with no problems. It now only boots as far as the first LG Logo screen.
I can't reach recovery mode.
I could access download mode, however after trying to re-flash using LG UP, my PC no longer sees a connected device..... same with LG Bridge, same with LG Support tool. USB driver is installed and verified by LG support tool.
I bought this from value basket but live in the UK - to date Valuebasket's customer service has been the worse I've ever known so I don't think they'd be any help in getting this damned thing fixed.....
Any ideas on how to get this thing back to life?
Thanks :good::good:

I have a peculiar problem, somehow my 5Z has stuck on Android 8, problems started when i was trying to install android 10 beta version(phone bricked and i downgraded to 80. version to recover phone) and iam unable to update since then, if i manually put update.zip in root folder. system recognizes and updates the phone but after restart giving update failed error , I lost mobile signal too with any sim. After multiple failed attempts, i decided to root and unlocked the boot loader, now iam getting a red warning whenever i restart my mobile. How to update to latest android version and get back mobile signal. thanks
