Any ideas what should I do? Thanks for every help!

I've Tried, tried through LGUP and it showed me unknown model so I couldn't do it with LGUP. Also tried with lg flash tool and had a disconnection with server and couldn't flash...
When I try to flash the 6.0 kdz it has the same message but after a while I press Retry and it flashes the 6.0 kdz.. after flashing the phone will turn on and work for a few minutes (not 100% ok) and then shut down again, with the ability to turn back on after removing and replacing the battery (and the all shut down process continues).

Think you flashed a KDZ that is not for your model.
I thought so too for a while, but i Double checked and I'm flashing the kdz for D855 European Offical (which is what I have)..

Thanks for everything, for now it works. I flashed all over again the marshmallow version and this time it didn't even turned off yet.
so after a day of using the phone is shutting down again and won't boot into recovery (since I have stock recovery) and won't boot into the android system - can only get into download mode. what should I do?
Maybe you have a battery problem, try another battery.

that's what I've been through: kernel crash due to connecting the battery when the phone was connected to pc with usb cable. than after many times I tried flashing through download mode with lg flashtool it worked for almost half a day and then suddenly it crashed again (when I tried to install spotify on my phone). all through the process when I tried to flash a stock rom with LGUP it wasn't possible because of unknown model error. right now I re-flashed the marshmallow version (because for some reason that's the only stock rom which I can flash and it would work from time to time), and it crashes all the time after a few seconds of using it and getting back to boot loop. Mods I can enter: Only download mode (no recovery and crashes when try to turn it on)... Any ideas what my next move should be?

LG G4 Stuck In Firmware Update - Stock Reset?

Hi, recently decided to reset my phone back to stock as I had some trouble with a few programs after resetting my phone. I tried factory reset but the programs didn't work so I decided I would try to just restore to stock and start fresh. I followed a guide on how to do the stock restore using LGUP/LG Flash Tool. I followed the guide and put the KDZ File into the program and pressed cse flash. The program worked till around 12% then it got stuck and just didn't work anymore. It said error so I kept trying over and over as some guides on this problem said to keep trying.
Nothing has happened and my phone is now stuck on firmware update screen. I have taken the battery out multiple times and replaced it back in and turned the phone on but it automatically goes to that screen after showing the lg logo. I have tried the volume down and power button factory reset but that doesn't work and tried getting onto download screen if that was any help but couldn't do that either. Now I'm stuck here... Any help? Don't have any other phone and can't afford to get a new one so I would like to try fix this anyway possible.
After failing the flash update thing the program says failed my phone says 0%. It went to 1% once and then just went back to 0% after it didn't work. So don't know if it's been changed in anyway. All help appreciated.
Did you have LG up set at refurbish or upgrade.....

I did refurbish first as I wanted to start new and it didn't work even though I did it a few times. I tried upgrade after and still nothing. Also have tried Uppercut and that does the same as normal LGUP.
The furthest % it got to was 19 on the computer and 8 on the phone and then it just stopped again. It usually stays between 11-19%. But most of the time 11%-16%
Have you made sure that it is the right region......
Try to down load just tot file and try that....

And what program should I use to do it?

H815, stuck on logo LG, after Hard reset Green screen...

Hi
I have a problem with my H815. In one moment i recognized that my LG G4 shows only LG boot logo.
I will make a hard reset. I have unlocked bootloader and imperium rom and kernel. After hard reset it
shows twrp recovery for a while and then stuck and then only green screen with text (on top - unknown reset)
And now it shows this green screen after a hardreset or during the second half of the hard reset.
Is there any way to try to repair it by myself?
Thanks Ondrej

Best bet would be to start over fresh reinstall firmware with lgup or flashtool and go from there
i cant instal firmware with lgup or flashtool. They didnt recognized the phone. The G4 didnt connect to the PC. Any other suggestions? O
Did you find the solution for this?
I have similar problem now.
I can get into fastboot mode, sometimes into download mode (but can't flash kdz) and TWRP. The problem in TWRP manifests when I try to flash new ROM (or whatever .zip file). I put it in freezer for couple of hours and successfully installed ROM while the phone was cold but didn't manage to boot into it.
Any suggestions?
