#Solution# Flashed Wrong Model Rom To D852.

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

[Q] My LG G Pro (F240K) stuck in the LG logo

Help!!! My LG G Pro (F240K) stuck in the LG logo.
I follow the link below to flash the Lollipop 5.0.1 for LG G PRO F240 K into my LG G Pro(F240K). It finished the update process but now stuck in the LG logo screen. I remember my original version is 4.0.x.. I didn't have a backup of my original kdz....
I just root my device but never flash any Rom before. Is there any problem to flash 5.0.1 into it?
I tried to download a Rom F240K10r_00.kdz to flash again. But still stuck in the LG logo. I don't know what to do now.

"CSE Flash" will wipe all data in your internal storage.
I also had bootloop when downgrade to 4.4 from 5.0 with "Normal Flash", then I tried "CSE Flash" and It worked.

LG Optimus G Pro E988 Bricked Issue
Hi there my friend I have bought LG Optimus G Pro E988 recently but 4G LTE was not working on it so I tried to update its ROM and while doing it unfortunately it bricked. Now when ever I tried to power on my phone it shows LG sign and reboot again and again and nothing pop up i tried many things with download mode but it does not work and it is also not going in recovery mode and I cant find its bootloader. Can you please help me this

Hi all,
Still confuse and not understand. By yesterday night after downgrade my LG OGP F240l (U+ Korea) and successful with Sim Card Disable I leave my OGP on desk until morning and low ?Then i try to OFF then pull out the SimCard and try insert the Simcard and ON my OGP fortunately thw simcard read and have signal but Service disable on screen. I have hope when the signal show. Just check the hidden code set the network show LTE. Try to WCDMA/GSM reboot the phone the issue FIX. Now my OGP fully work with Kikat and try to Flash again to Lollipop and successful my simcard fixed. Correct i am using CSE to flash and its work. I think the phone baseband installed try to stable and optimize it self first to network on my country.
Now my OGP running Lollipop (no root).
Regards,

LG G3 D855 Signal Problem + Cust Error

Hello everyone,
I own a LG G3 D855 and recently I've bricked it. What I wanted to do was to flash official ROM (V30N) with LG Flash Tool 2014 back because I've had LineageOS and it had some bugs. Before Lineage OS there was V30N EUR and everything was working without problems.
The flashing process had problems, it was taking too long. It went to 4% in 30min and then it went to back to 3%. I knew there was no way it will finish so I've unplugged the device and tried to flash again but it didn't boot into Download Mode anymore. The device was turning on with a message: boot verification fail! cause: mismatch_sig_len.
To fix it I've followed this tutorial: https://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
But somehow my IMEI was gone so I fixed it using this tutorial: https://www.youtube.com/watch?v=y2lHFy7AciE&t=472s
(used the IMEI from the back of my phone)
So now this is the PROBLEM:
Everytime I flash V30N i get cust error at start. If I flash V30B global there are no problems with cust BUT:
No matter which one Im using my signal drops every time, especially when I turn my data ON or OFF. Sometimes the phone shows X on top of the signal bar and there is no service or it's endlessly searching for network. If I reboot it the signal is ok for a while.
Now what can I really do? Is there a way to rewrite EVERYTHING with a EUR TOT ROM? I'm downloading TOT files from here: http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/
Thank you, any idea is highly apreciated.
Note: The SIM is OK.
Note2: I've flashed with BoardDiag V10e and V10a, same problem.

im having the same problem. hope you can help me when you find a way to fix this. Thanks!
