i think is was misinterpreted. its a h815 but a h815t indeed and unlocked mean carrier as you know theres no way to unlock bootloader.. you need to flash the h815T KDZ. i hope that you didnt mess your imei.
inject only works in LP not on MM. also youll need to find out if you can downgrade to lollipop. as this phone have antirollback wich means once you are on a version you cannot go nack or youll hard brick phone.

thank you for the response.im on lollipop right now since ft 2014 doesnt flash MM and lgup and ft 2.0.1.6 stop flashing after checking phone info(they stop flashing as phone shows h818 but kdz is for h815).I flashed h815T kdz multiple times(twice just today)but phone still shows h818 in lgup and in settings.the phone cant be h818 as it only has 1 sim slot.
imei is ok right now.SIM issue happened to be a ****ty sim cut job by the customer service guy.only remaining issue is the wrong version showing up in phone settings. cant flash MM due to that.
also,is there anything good about upgrading to MM???

Actually MM isnt an upgrade. Lollipop is best(maybe nougat will be worth anything). I think you should flash uk v20g kdz with lg up(or LG firware flash 2014). I suggest using LG UP also you can give TOT method a try

Do they check in build.prop? If so just change build.prop value and you're good to go. I think that there is also possibility to fake your software version and then flash anything you want

I got fulmics ROM (MM), I tried to flash with KDZ method but it stuck at %10, i think because i have MM, so i tried TOT method but it says "Device model is different! Check phone or dll, my lasy chance was using LGUP but it says Unknown model maybe because of rom or my device model being D855TR (Turkey), I can't find any TOT files for D855TR, I am now stuck at Download Mode, I need to return to stock because I will send my phone to carrier for yellow screen burn.

I found a solution and fixed it now i can boot up the phone, I downloaded HxD editor, and edited the .tot and .dll file. Open the .dll file with HxD editor and search for word: "d855" and add your carrier's letters, i changed it to "d855TR" it is "d855p" for you, then open the .tot file you downloaded and do the same on it. Worked fine with TOT method. and you also need to do it on windows 7 i think didn't work on my windows 10 always stucked at %10 but i made it on windows 7.
I have two LG g4 . both of them refurbished and korean version ( i've searched iemi and found them, one of is F500k and other is F500s) but flashed as LGH815 rom (rom version lollipop H81510h .)
after flashing H81520j in my F500s model it wont turn on. but i can hear boot sound. also blue LED beeps . if i pressed volume button i can hear sound. I flashed it with LGUP and it flashed perfectly but not booting.
i've flashed the same rom in another device ( which is F500k) and working perfectly.
i've also flashed perfectly other rom version. which are...
1) Europe H815D kdz
2) Europe open H815D kdz
3)H81520i Kdz
4) LGH815AT-00-V10h-GLOBAL-COM-AUG-25-2015+0.tot file
I can not boot my F500s device right now. no download mood. but device manager showed it as LG Androidnet Usb serial port.
also detected by LGUP but trying to flash it via LGUP but it says KDZ file is invalid.Tried same KDZ which flshed earlier but no use . when i open LGUP phone setting option it detects as H818 device .
tried in LG flash tool 2014 . but not working . also tried with connecting LG bridge but MTP mood is disabled .
i think it is not hard bricked. plz help me !!!
Sorry for my bad English
okay guys.... finally my phone is alive..!!!!:laugh::laugh::laugh:
my phone was recognized by LGUP by all af the KDZ were showing error..
so when i saw after clicking phone setting of LGUP that my phone is showing H818 version ( i don't know why the hell is that coz i didn't setup any H818 version rom) i first download a H818 rom . which was a tot file. i installed it. i was amused to see that is was installed where other kdz were detected invalid. but although i setup that phone wasn't booting. so then i edit a H815 rom and setup it .
which was "LGH815AT-00-V10h-GLOBAL-COM-AUG-25-2015+0.tot"
it installed perfectly but my problem still remains.
and then i installed "LGF500LAT-00-V11d-LGU-KR-SEP-21-2015+0.tot" file ( i have to edit it too.)
and horray.....!!! my phone is alive....!!!!!!
but i've to FRP by pass it.
by the way.. i've a question . which one is responsible for network ? " modem, boot or any other image ?
if i extract that img from this korean version and use it to a global version will it work ?
Sir please tell me how you edit LGF500LAT-00-V11d-LGU-KR-SEP-21-2015+0.tot file i have edited it with Hex editor changed model to H815 as i have flashed H815 uk rom on my LG F500L
I want to unlock my LG 500L(I guess everyone wants that right ) which is updated to nougat.
I tried to downgrading using the F500l20u kdz from lg firmware using LGUP but it failed at 11%.
Replaced the .dll file , still no luck.
Tried to go back to LP using the tot but it failed giving the unknown command error.
So if anyone of you who want to support the unlocking of LG g4 F500L with nougat can give me suggestions on how to go back to MM in order to flash the USU.
Flashing back the Nougat kdz works fine though.
Hello and Good Day to everyone.
I have a problem with my LG G4 (H810) . At first it was not booting at all (no power), so i tried the unbricking trick (QFIL+shorting the two points in the motherboard). I got through with it successfully. I then proceeded to the download mode. My next step was to flash an H810 KDZ. First, i used LG UP and got invalid tots on all H810 roms i've tried (Puerto Rico and AT&T). I looked at my phone's screen and i noticed the line "LS991ZVA". I then tried LG FLASH TOOL 2014 it gave a download error saying (LS991-->H810). I also tried LGFlashTool-2.0.1.6 and it still says download error at the end. Is this still repairable?
PS:
There's was one point when i looked at the screen and instead of LS991ZVA at the bottom, it showed H815AT_(i forgot what's next). I tried flashing an H815 kdz and it didnt show that invalid tot but the new error showed "antirollback". I was rushing to work so i wasnt able to download a newer H815 kdz. I tried to recreate that scenario in the office but now i'm stuck in LS991ZVA line again. I don't know what i did made that H815AT_ line show in download mode.
Hope anyone can help. Thank you.

Can I ask how you got the H810? It sounds like you may have a frankenstein device (one model motherboard with a different firmware flashed)
Maybe @steadfasterX knows more

It was sold to me by a friend for 16 dollars because the phone wont turn on anymore. My original plan was to only take the Screen Assembly because I also have a G4 (H818P) but the screen already has bubbles at the sides and sometimes ghost touches happen and also there's that annoying temporary screen burn-in effect everytime i stay on an image for too long. I tried to take everything apart and put my H818 motherboard onto the H810. When i turned it on, the screen don't show anything and the notification led flashes (light blue) and the phone would then turn off. Right now, i'm trying to repair the H810 so that atleast i can make it my main phone.

congrats.. regardless of your real model you converted your device!
QFIL is nothing an average user should ever do as long as not guided by someone..
what you see in download mode, recovery and android is just software so even when you see IOS v22 there it doesnt mean anything.
what u see in fastboot is true, you have converted your device to a LS991
the very first thing before flashing again random stuff or even worse using QFIL again is: identify your real model (even when now converted).
the only way to do so is to disassemble the device and look whats written on the front of the mainboard (sounds harder then it actually is)
https://www.ifixit.com/Guide/LG+G4+Motherboard+Replacement/51202
Then when you KNOW what you really have we can proceed

Okay got it. My original plan was really not to fix it but only to reuse its screen on my H818P (unfortunately, i think it's incompatible). I will look into it (mainboard) when i get home. Thanks Mr. SteadfasterX

yep classical Frankenstein. you have a F500 refurbished with a H810 firmware.
you flashed with QFIL the malware LS991 files (yes its known that they are named for several models but many contain the same files - which converts all to LS991).
LS991 has ARB (atm you have an ARB of 2)
F500 and H815 dont have ARB
you cant flash any firmware lower then ARB 2 and so you can never flash F500, H815 or H812 ROMs anymore! (and do not even think about flashing a firmware with an ARB of 3 or higher!)
For getting mobile network signal you need a successfully loaded modem which will never happen anymore as you increased the ARB. that means even when you get your device back to work you will be only able to use it as a tablet (WiFi, BT etc will do but no calling,sms,mobile internet)
ARB? --> https://bit.do/antirollg4
you can bring back life back to this device by:
1) flashing a LS991 rom (ensure you use ARB 2 only)
2) MAYBE !! flashing a H811 rom (as H810 bootloaders are compatible with h811) but ensure you use ARB 2 firmwares only !
If that works: congrats! you can now unlock by a fastboot command and thats your best chance to maybe even get mobile signal back! (no one ever tested that though)
3) you may try to flash H810 10o which has an ARB of 2 and is also a very good chance to bring back life to your device - maybe well I would say very likely the best one!
4) flashing the partions system , modem and boot of any ROM (yes even of a f500,h810,h815... as these single partitions do not increase your ARB) you like within fastboot (yes you can now flash there bc of .. that would take too long. I know you will be able to do so as I use parts of it in UsU)

Should i try from 1 to 5 sir if which one will work? or Should i try (3) first since it's the best one. Also, which one would i use to flash, LG UP or the lastest LG Flash Tool? Thank you.
Is it also possible sir that an H810 screen is not compatible with my H818? If I wont be able to use it as a normal phone, i might as well use it's screen on my H818P. I did try but there's no image. The notification lights only flashes color light blue and then the phone powers off (takes 15-20 seconds after clicking the power button).

yes. the screen for the h818 is incompatible with the h810 one as the h818 uses a different panel then all other 10 g4 models..

Why not using Wi-Fi? At least for the moment. No you can't flash the f500 modem partition because it has arb of 0

Yes I hexedited the H810 10o tot because it's the only way to flash it in LG UP as LGUP is detecting my phone as H81510C. So i just replaced 1 line in H810 10o into H81510c.
My problem is i need to bypass the email verification screen. I don't know the email that is associated with this phone. Most of the youtube videos i've seen on how to bypass is they use emergency call. When i try it, the phone just says "turning radio on". Any other way to bypass that email verification screen without the use of emergency call? Thanks
@steadfasterX i wasnt able to bypass the email verification but i was able to go to the settings menu. Is it safe to update this phone to marshmallow? It's currently on 5.1 Lollipop. Maybe it will increase ARB so might be a bad idea.
