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

Ok so here's how it all started:
My phone was randomly shutting off and rebooting on its own. At first, I thought it was overheating because the phone was very hot and when it cooled down, the problem was somewhat fixed.
Now, the phone randomly shuts off and reboots 90% of the time and I don't know why. It has a bootloop problem, but for some reason, I can occassional get my phone to load fully if I plug it in to charge, but it goes back into a bootloop after a few minutes or use. I tried a factory reset and it didn't work. In fact, it bricked my phone as it's now in a bootloop.
I tried a normal Flash using LG Flash Tool 2014 but for some reason it always crashes. First, it gives me a "Connection to server failed" error. But for some reason, the LG Tool keeps working as the status bar % goes up during the "upgrading phone" phase. However, when it reaches 99%, the LG Flash tool crashes. I tried both a normal Flash AND a CSE Flash. Both didn't fix the problem. It could be because the Flash Tool crashed, but nowhere on this forum does anyone talk about a fix to the "connection to server failed" error or the LG Tool crashing. Now after the initial flash, however, my phone does turn on and load up, but I get the same issue as before where the phone would crash/reboot after less than a minute of use. Then it bootloops after.
Am I the only one with this problem? If you have a solution, please let me know! My phone's useless at the moment. If I you can figure out why my flash tool crashes, that would be great too because if I can get the tool not to crash, it might flash properly.
Please and Thank you.
I have a LG G3 D855 International (Taiwan Version TW) running Lollipop 5.0
Have you tried the lg flash tool without the 2014 after it? I mean using the dll and tot files?
Usually if one does not work for me the other does. Just depends on how my phone decides to work lol

Sadly, I can't use the TOT method because they don't have my version which is Taiwan TW D855.

hi there. when you turn your phone on does the LG logo just coming in and out slowly? like blinking slowly? if yes, try to buy a new battery. i had that same problem. i cant even use my phone anymore because it just kept on shutting down. i can only use my phone when its plug into a wall charger. when i remove it to the wall charger it shuts down and the LG logo will start to come in and out as if blinking slowly. i tried factory reset a lot of time but didnt solve the problem. so i went to the LG service center and they just put in a new battery and it worked fine after..

I have a G3 D855 taiwan versión, too.
download the latest kdz and flash it. who knows the one you are trying to flash is corrupted.
ignore this message "connection to server failed" .
try to use different usb ports and get a new battery just in case.
Hi...i have the same problem.
Did you find any solutions.
Thanks in advance

Try using a spare battery if you have one, might fix the problem?
Thanks It did solve the problem.

Thats great! Same thing is happening to me, my new battery is on the way. Hopefully it will work
Same symptoms here - started as random reboots under heavy load or using the camera, so tried reflashing from v21a LL KDZ.
Then bootlooping just after the LG logo, occasionally getting as far as fully booted, but then restarting near immediately.
Doesn't happen when connected to power.
Tried a different battery, and no problems.
Tried my battery in another G3 - identical behaviour there.
Note: also happens on Marshmallow.
Solution: New battery!
Thanks to posters above.

You can try....
http://forum.xda-developers.com/lg-g3/help/okay-lollipop-flash-kdz-android-mm-fix-t3283666
you can try rom TOT, you can change ver 10a, or 10b.... then...(if flash success in 10x TOT), kdz again into 20x
I'm from United Kingdom and I have a LG G3 D855 - made in Korea and basically what's happen to my phone is I restarted it and it ended up in a firmware mode and everytime I take battery out and put it back in it sends me to that firmware mode so I gave the phone to the shop to have a look and he says the whole software of the phone has been wiped off, I tried to flash it using your method if my phone gets messed up or something but everytime it would get stuck after 10% so I handed the phone to the shop and basically he put a software on and it says V10J-GLOBAL-SI. But before my phone went messed up it was something like V20I-EURR-XX, I've been searching for files so I could try and get my phone software back but I don't know how too, I heard of 'KDZ' but what is the difference between tot file and a kdz and will the Europe kdz get my phone software back to normal or any method that you know that will get in back,
please reply I've been proper stressed.
Hey!
two days ago, out of the blue, by device restarted it self, and started to to it every few minutes.
after that, it just stuck in bootloop tho it was able to turn on for few minutes once or twice,
I tried to recover to factory settings from the phone, re flash the latest version with LG bridge, and use the flashing tool to reflash the kdz.
it always goes back to booploop(I think)
download mode works and not crushing.
any ideas? I

Unfortunately, the same thing's been happening to a lot of people lately. I'm getting bootloops on my G4 but it hasn't happened enough for it to be a problem. Once it becomes more of one, i'll send it in to LG under warranty. I would suggest you do the same too (LG warranty is 15 months from the month the phone was made - that info can found on the outside of the original box) Good luck!
