Hi !
I'm having a big problem right now. Few days ago, I tried to Root my phone everything was fine. The next day I wake up and go on my phone and there is a boot loop when I try to open it and it never ends. It's a loop at the LG life's good logo.
Few things I tried so far before coming here:
1) I tried all this :
http://forum.xda-developers.com/showthread.php?t=2785089
When I do it with LG Flashtool 2014 it goes to 4% then it stops/crash.
When I try with LGFlashTool I get : Model Information: Check FAIL! (but I put the good model in the files)
2) I tried a hard-reset but when I do the hard-reset it goes back right away to the Boot loop.
3) I tried with LG PC Suite, but the it says Mobile Device not found so I can't get it to repair with LG PC Suite.
I don't know what to do anymore.
My phone is a LG G3 D852 (Canadian)
Hopefully you guys can help me out here. Thanks a lot
Well apparently doing it on another computer fixed the problem!

Hello,
can you please help me bring my LG G2 D802 back to life?
I had problems with GPS on LG G2 D802 4.4.2 so i tried to go to 4.2.2.I had some experiences with flashing from previous phones so I though I will be able to perform also this one.
I followed http://forum.xda-developers.com/showthread.php?t=2797190.
I stopped on 61% on mobile and 53% on tool. Then i used official LG tool, to recovery, but it stopped on 31% or so. Then i used different FW - with this i could get on 100% mobile - but only 89% on LG flash tool. Then I download official LG firmware according IMEI, but unfortunatelly I was again not successful and was not able to get into download menu. When i connected my phone to PC, i got many pop up windows asking to format many various disk on phone.I was not able to get into recovery mode to perform HW reset.
So i decided to to use instructions from: http://forum.xda-developers.com/showthread.php?t=2582142 with help of mine who is Linux expert.
After this I again get only LG logo when i start phone, and im able to go to recovery mode. I also can start HW reset, but it is doing nothing, just showing: performing hw reset. When I connect phone to PC even that it is switched off (it looks like that) it starts and stop on LG logo, but PC cannot see it. Also it sems, it cannot be found under linux as well.
Please help me.
Thank you very much
Tomas

Hello Community,
Yesterday my G3 stucked in a Bootloop without changing anything. Than I wanted to repair it with the LG PC Suite. This failed with the message "Assert" multiple times. Now it stucks in the download mode. Can I repair it? More important are the files on the G3. Is there a way to get them?

Try this:
1) Remove battery
2) Hold down the power button for 30 seconds with the battery out
3) re-insert battery
4) Try turning it on again.
If that doesn't work, do a hard reset. You can find multiple posts on how to do it. Hope this helped!
Maybe I can help somebody with the same problem. I solved the problem with the following steps:
I setted up a new Windows 7 x64 PC. It must be Windows 7!!! No Windows 8 or other shiny things.
Installed the driver
Flashed a compleltely new firmware (.tot) over the old (!) FlashTool.
Hi guys. First, sorry my poor english. I'm Brazilian.
I make a firmware upgrade from LG PC Suite, 4.4 KK to 5.0 L. Problem is, the upgrade failed, and now my LG G3 are stuck in download mode. I try make this upgrade from LG Flash Tool but the problem persists, 65% appears in the screen of LG G3 a message "ASSERT" and reboot to download mode screen. Help, please?

Although I have never come across this, using this site to download the right KDZ and using this thread to flash that KDZ may solve your problems. There is no harm done in trying this and you can be sure that it is the right file.
LG G3 Boot problems after download mode
Hello!
Sorry revive the topic but it was the only one who found a similar problem, after searching lot on google.
I have a LG G3 D855P. Yesterday he went out and restarted many times, but worked for a short time.
I can use the BoardDiag, but when I restore the D855P20C_00.kdz .kdz, to reach 36%, the cell phone goes off and does not return. I need to take the battery cable, so that it returns to the download screen, but still, to get 36% he goes again. Have made sure that the .kdz file works properly.
I followed the tutorial presented in this video.

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

My phone was bricked hard and i had to us many tools to unbrick it and it worked and i have opened download mode band started lg flash tool but every time it reaches 100 the screen goes black and lg flash tool fails to flash and the g3 returns to 9008 again and i restart doing it from the beginning for about 7 times.
The problem is at the last time i have unbricked the device with a different .tot i guess and it did the bad thing.
My phone shows the lg logo of boot for a second and turns black. Then comes agin for a second and turns black.
And the sequence have going for about an hour
And the download mode do the same and its not opening even so i guess that the best way to solve the problem is to brick the phone again.
But this time its my choice to.
So i need help
I think you are flashing wrong tot.make sure the model of your mobile and then flash the exact tot.
My LG G3 kinda died in sleep. It powered off during the night and once I woke up, I tried to turn it off but it's now stuck on LG logo screen.
For a month now I've been going through other threads about this, but still can't find solution that works, I'm not sure if I missed anything.
Phone status:
- It won't boot further than LG logo screen
- From recovery mode, there is only 'Factory reset' option, which I've tried several times, but once again it gets stuck on LG logo
- I can go into Download mode but can't get it to work
So far I've tried with TOT files - LGFlashTool (version 1.5 and 1.8)
and KDZ - LGFlashTool 2014
With earlier versions (TOT files) I got message: Model check information FAIL! - Screenshot: i.imgur.com/N6sxbEt.jpg
And with LGFlashTool 2014 (KDZ) I got: Connection with server fail - Screenshot: imgur.com/wD6vWL3.jpg
While I'm not sure I'm using correct TOT files for my device (it's from Switzerland and has 6SW mark so I went with Europien files), I know that KDZ are good (I've used IMEI search option, so that's all good), but that doesn't even matter since it won't even comunicate with the damn server in the first place.
Any suggestions would be highly appreciated, I've lost all hope :/
Thanks,
Matt
hi bro.
try forcing phone to boot in qualcomm 9008.
and unbrick it with board diag.
for booting phone in 9008 mode you should open back of your phone.
google G3 test point)
on xda you can find few thread about unbrick.
if you couldn't repair it send it to LG Services for repair.
