H811 fried? KDZ won't work - G4 Q&A, Help & Troubleshooting

So I'm pretty sure my phone is fried. Just wanted to double check with anyone before sending it in.
I was driving and streaming music to my car when it stopped, and I noticed my screen wasn't responding. Swapping the battery only showed me the LG splash screen before restarting, showing the splash screen, then shutting the screen off and not responding. No length of time will let it boot.
I have everything on my SD card so no worries, I tried wiping from recovery. TWRP booted, froze, screen shut off and the phone was again, unresponsive.
Last resort, restoring with the KDZ. I got it into download mode, waited to see if the screen shut off again, and went ahead with flashing after I saw it was ok. It finished up and rebooted, and once again all I saw was the LG splash screen. I got to the "Android is upgrading" screen at one point, and it froze and shut off the screen again. It was, again, unresponsive.
tl;dr
Phone crashes, even after KDZ flash and master reset. Is there any hope I can fix it? I have a backup phone in the meantime but it's so horrible, I miss my G4!
Thanks for reading.

Better send it. Got crazy bootloops myself.
At the end even couldn't charge it. After i got it back i asked what was broken, they told me that it was unable to repair mainboard and usb port and they put new.So my advice let it fly to the repair shop.

Non-rooted LG G3 D855 suddenly stuck on boot / can't get into recovery

Last night at a party I go to take a picture by holding down the Volume Down button whilst locked.The camera app didn't pop up and subsequently my phone crashed. I thought nothing of it, but then it wouldn't turn off or recognise anything. Even when I popped the battery out and in. It's stuck on boot. So I let it run out of charge, go home, charge it and the little battery icon animation that goes round once you've turned it on gets stuck, I can't tell what the phone's percentage is - it just stays frozen. Stuck on this now instead of boot.
After about 10 minutes of it being stuck suddenly I got the error message:
[784680] Fastboot mode started
?!?! What gives? I only rooted it once but then flashed it to stock immediately when the phone first came out and I've left it as is since.
Any help is really appreciated. I need my phone for work tomorrow.

My phone did the same last week. Still haven't found a solution. Can't enter Download mode, as it hangs even there.
Same Thing
Bumping for the Guy as the Same thing happened to me.Any Kind of Help would be highly appreciated!
same
This is the same problem I have
Update: I sent it in for RMA. Will be receiving a replacement unit today. Seems like the only way around it, if a swap is the way to "fix" this.

Phone won't boot

Hi All,
My phone will not boot. I have tried soft resets multiple times. It will not even boot after I selected the factory data reset by holding down the volume down and power button since it seems like that requires a full boot to reset. During boot it shows the LG logo and sometimes makes it to the AT&T logo but after that either black screens, back to the LG logo and powers off, or boot cycles and keeps showing the LG logo multiple times. I have taken out the SD card and tried all these steps with and without it. Took out the sim card and reseated it. The phone is stock and not rooted.
Let me know if you guys need more information or have any ideas.
Thank you all and I'm sure this is been solved before, but I'm at work and don't have time to research so thoroughly through all the threads/posts.
if it's not rooted and stock, i'd send it back to lg under warranty

I have already put in a ticket to LG before this post for their return shipping information and repair. I was just hoping by some miracle that someone had a fix besides a factory reset since it won't even boot to allow the factory reset.
Thank you
Ok, sorry for the lacking help! Good luck, hope someone else replies with a suggestion
This just happened to me too.
Shows the lg logo. Sometimes the att logo.
But, just doesnt boot up. All i see is a blank screen :/
From everything i read here on XDA it seems that many of the phones are faulty.
Symptoms are almost identical. Outta no reason reboots and dead phones. Many of them are stock not rooted.
I have still no answer from LG about mine. Hope to hear soon. Something is going on with these phones but what causes it.....that`s the question....
The same thing happened to my H-815 model. I went to bed listening to YouTube and woke up to a dead phone. The LED doesn't come on when charging. Just like you, when I turn it on all I see is the LG boot screen and then it shuts off. The phone repeats this twice and then doesn't turn on again.

LG3 wont boot + Blue screen

Hello, i faced a serious problem this evening, just after i finished a call phone, the screen of the phone went Blue and then it went off, i started to put it on again and then it showed the screen with LG and then it went black no boot at all. i removed the battery and i tried again and still the same, so i tried to remove the battery and put it again and plug it with the computer, it went on with charging battery and then suddenly went to blue screen again.
So i tried to put the recovery mode with power down and on/off and it worked i got the recovery mode screen with factory reset but it was only with factory reset, i tried it and then i put yes and it reboot and then after LG screen, it went black again....
so i tried to put download mode with usb cable but it wont, always i got the blue screen. what should i do, where is the problem exactly for people who had the same problem ? the batterye ? the motherboard ?
anyone to help ? i changed the battery and it wasnt coming from it, and the phone showed others anormalies like sometimes u can charge the battery and you see the % and sometimes it goes blue screen and shut down. anyone had the same issue before ?
My LG G3 randomly started giving this problem for 3-4 days till it went completely bad. It just wouldn't get past the Blue Screen. Since I had to take a backup before taking any further action, I have been able to get it up and running for very short durations by keeping the cell phone in the freezer for an hour or so. Yes. I am not kidding. After it freezes, I can get it up on about 5th or 6th attempt. Sometimes even more. Be mindful that the battery is now showing a red humidity marker due to the freezer.
I am thinking of asking LG to repair it. What a piece of crap. Its only 18 months old for me.

LG G3 unresponsive/extremely slow

Hello there. I have to write this again becuase the last topic I wrote didnt get posted...
I have a big problem with my G3 and I have tried everything I could but nothing helped so I hope you can help me.
First of all my phone is only stock. I didnt try rooting it or installing custom roms on it.
Heres the whole story of what happened:
A week ago my phone started to act strangely. When I tried turning the wifi off it restarted or froze for a bit and then went on normaly as if nothing happened. I didnt even have to input my pin. Then one day I got home and the phone simply started reseting itself constantly. Always loaded up to the pin screen but I didnt even have time to input the pin and it reset it self again. This went on for like 15 reset before I lost patience and pulled the battery which didnt help at all since after being turned back on it went back to the reseting. I found online that it was probably a battery problem but I was impatient (shipping to my country is over 2 weeks and buying a battery in stores here costs twice the normal price of a genuine battery but only for a "fake" battery) so I factory reseted it via power button+volume down. After that it worked normally but I lost all my data.
The day after this I spilled ice tea on the phone. I opened it, cleaned it and let it dry out. Turned it on after an hour of drying and it worked but after maybe 2 hours it began freezing. When I tapped on the screen it didnt react, when I pressed the power button it took more then 10 seconds to react to it. It turned on, didnt react to touch and then in mere seconds it went dark and then turned off. I couldnt even unlock the screen. Tried pulling the battery but then it wouldnt even turn on. It stayed on the LG logo. I left it on the logo and on the charger and after an hour or so it turned on and worked normally so I took it apart and cleaned it once more even under the screws and such and it worked after that. Until today.
The freezing problem returned. I was playing a game on it and chatting via messenger when the phone stopped reacting. I had signal, wifi, I got new notifications and basically everything on it worked but the screen didnt react to touch and when pressing the power button it took over 10 seconds to light up the screen, then it went darker and then it shut down. Couldnt do anything. After I pulled the battery it would get stuck in a boot loop for maybe 10-15 minutes and then load but the phone couldnt be used. Just as before the screen turned on with a delay but no reaction to touch whatsoever.
I tried factory reset, downgrading to a lower android version (from 6 to 4) with LGUP and lg flash tool, and I bought a new battery. Nothing worked. I managed to get it to android 4 but that didnt help either. I though it was a problem with 6 because the problem started after the update, before that I didnt have a single problem with my phone.
Now its in a state where it doesnt work. The phone is running, apps are upgrading after the factory reset and all that but I cant do anything with it. Once in a while it will work normally as if nothing but that is rare.
Could you please help ? I love this phone and I dont want to have to sell it for spare parts.
EDIT: I left the phone running to see what would happen an after several hours an error message appeared saying "Process system isnt responding". After pressing ok it worked fine. How can I fix this. I googled it but all I found was a problem with sd card (none is inside), with battery (I have a new one) and with rooting (mines not rooted).

D855 completely unresponsive, tried countless ROMs, now stuck in a boot loop.

Hi, so a week ago I had this weird problem with my phone. It would just freeze for like 2 minutes, work again for a minute and so on.
Did a hard reset, same problem.
Flashed that 6.0 KDZ, no success. The phone started but I was basically stuck at the lock screen, touchscreen was unresponsive, power menu kept showing up for no reason... couldn't even turn the phone off.
After that, I decided to stop ****ing around with it and send it to a repair store (no warranty). Today, after about 5 days, I picked it up and was told that they tried a ton of ROMs but they have no idea what's wrong with it.
Got home, ran a hard reset again and now I can't even get to the lock screen, phone is basically in a boot loop. LG logo shows up, the "Android is starting... Optimising apps" screen does its thing, restarts and keeps going like this forever.
Is there anything I can do or should I just throw the phone in the garbage and get another one? Any suggestion is appreciated, thanks!
Hi,
Same issue for 2 days...
My G3 was suddently slow and unresponsive so I removed the battery.
I put it back again, as usual, and start the phone. But it get stuck at the LG logo.
Sometimes the animated LG logo shows up, sometimes not.
Sometimes it displays the PIN screen (unresponsive or not), sometimes not.
Sometimes it boots totaly normaly (1% of time) and become unresponsive/buggy after a couple of minutes.
I tried flashing kdz (normal and CSE) 10 times, factory reset, change battery, without success...
Good luck.
