LG G4 H815L running v20d.
Since V20D is crap, I want to move to V20h (its not my first time going back and forth).
The problem is, this time, that for some reason, when i put my lg g4 into download mode and enter LG UP, its detected, but shows instead of READY or something like that "STANDBY".
And there is no functionality from there. I can't really do anything.
Please help!

Hi,
i having a big issue with my lg g2, i killed my phone , this is what i did :
i have a lg g2 vs980 and another one ls980, so i put on the vs980 the cloudy g3 to get the phone like the lgg3, so i rooted and installed recovery using autorec, and everything it´s perfect in the vs980, but i made the mistake and used the same files to do the same in ls980 after restart phone was stuck at : flashboot mode started udc_start(), then reading some forums i got what i though was a solutions using adb tried to flash a new rom and what i get was everything was deleted from the phone now when i connected to the computer a lot of disk images pop ups, asking to format them, and the phone now it doesnt show even the lg logo. when i press and hold the power key the red light blink but thats all.
can somebody help me please???????:crying::crying::crying:
Go look up the instructions on how to get it into download mode and use the .tot file to restore it to stock.
You will lose absoutely everything on the phone though.
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

Hello Everyone,
i need help reviving my lg g4 and i search all the forms but no avail. I just got a G4 4 days ago only it was running lollipop and working fine i just check for the MM update in phone but there was no update so as i previously own a lg g4 with flumics rom so i decided to flash a kdz with MM update. I see my model no. as h815 so i download H81520h_00_0516.kdz and flashed it through lg flash tool 2014 it flashed without no error but after the flash i got no display in phone just blue led flashes and i hear lg boot sound and then just nothing on phone display it switched off itself. I try to go into hard reset but again no display i try to go into download mode again no display. I attached it to pc it shows LGE Mobile USB Composite Device. Although it shows in lgup tool as H815 and port no. as well.I search my model no. through IMEI i found that it is actually F500L model as i see Korean as it flashed 1st time in download mode. After some research i manage to go into download mode by removing the battery and attaching the phone to pc as it shows empty battery icon so i inserted the battery by pressing the vol up button it goes into download mode. So i try to flash the right firmware which is F500L20u_00_0504.kdz bhut lgup says it invalid kdz i try to flash it through lg flashtool2014 but it says cannot connect to server and failed with contact system administrator. Although it flashes H815_EU_10C_00.kdz and India H818N10d_00.kdz firmware's but those give no display at all i tried it with Lg Bridge as it shows update avalable F500l and it download it but failed to flash it. I try flashing korean tot file LGF500LAT-00-V11d-LGU-KR-SEP-21-2015+0.tot through lgup tool but again it said invalid tot file So friends i am stuck and looking for 5 days to find any solution So anyone can please help me i just used it for 1 day . So can anyone help me.
You have to edit a F500L kdz with a hex editor and replace every F500L to H815 or something that flashes without error
First, if it's H815, you're to flash an H815 kdz with LG up

Put into download mode and refurbish the kdz accordingly.
I have a problem, after starting the LG screen.
It will probably be a software error because it does not have a bootlop. When Factory reset is turned on, it shows up, but it does not respond before the ending.
Download mode works, but LGUP does not open completely and wants to enter the model but where?
I've already explored everything with LGUP, the latest 8994 dll version, but it does not respond.
I also explored LG Tools, that recognizes my model H815, the update will run but always at 16% end.
Does anyone know what to do?
Well thank you.
Hi all,
I was wondering, once I have custom firmware and recovery on my lg g4, will I be able to reinstall the software from LG Bridge. I understand that I could use the kdz downloaded by it in LG UP, but I was wondering, if I put my phone in download mode, could the update error recovery utility in LG Bridge also reinstall it?
Thanks in advance for your help

I tried this recently just to see what it does, but it even didn't recognize the phone. So you probably need to use LGUP (which I used to go back to stock on my G4) or TWRP to flash something else.

I just tried it and interestingly if the phone is in download mode, it does get recognized as an LG device and will initiate an Update Error Recovery
