LGG3 D850 stuck on firmware update screen - G3 Q&A, Help & Troubleshooting

So my mom had an LG G3 D850 from at&t. was totally fine, then she updated whatever she had to 6.0 and it started bootlooping. Tried the LG Flash tool with a tot stock firmware. Went through the whole process got the blue screen with the red 3, it restarted, kept bootlooping. Tried it again but then it got stuck on 5% for like 4 hours, unplugged it and now no matter what i do i cant get into download mode. It shows the LG screen then goes straight to firmware update (even if i dont hold vol up) and it says 910K Bxx QEM (the xx changes) I was able to get into recovery mode, recovered it. same thing. Im losing my mind a little bit here so any advice, or pointing me to a tutorial would be greatly appreciated. Ive looked all over the internet and cant find anything helpful apparently the qualcomm thing where you short the motherboard doesnt work for this phone either?

If it is under warranty .send your phone to at&t to get it fixed.

Its not

i have same

Qualcmomm method you are describing is just to bring your phone into download mode. I have done this to my brother's g3. You have to flash using LG flashtool using different settings and then hard reset your phone. If it doesn't solve your problem.try to replace battery and then use custom rom.

tried that

no matter what settings i set LG flash tool to it doesnt recognize the phone. and no matter what i do the phone jumps to the firmware update screen, it skips the download mode screen. I have two batteries and ive repeatedly switched them back and forth :/ even after reseting the phone with factory reset it goes back go the firmware update screen

totally forgot to switch to com41, did everything exactly like that. got to the red 3, restarted it, and it still bootloops. i guess ill try a custom rom cause this stock one isnt working.

apparently cant do custom roms either, I got it to boot the the set up screen for 5seconds befores it crashed so i guess im throwing it away cause im sick of looking at it.

g3 Stuck in Download mode. Help Please...

I just got a new LG g3 sprint variant yesterday. Worked fine for about an hour. Started crashing. Green Screen with crash handler with options to reboot or dump. It would boot up and then crash again. Also received a Kernel crash black screen. So I decided to flash new dll file and tot file using lg flash tool. Put into stock download mode (firmware update Screen) and started flash. Went to 19% the screen went black acted like it turns off and disconnects and fails. Tried 4 different cords with not very different results. the furthest it got was 49%. Now it is stuck in firmware update screen. I remove battery and turn on phone it goes to lg boot screen and then firmware update. If the phone is off and I plug into wall charger the screen shows battery symbol with spinning thing and then firmware update screen comes on. Please help. Thanks for any input in advance. Posted in Sprint g3 section as well but no answer yet. Thanks

Read it. You might get Download Fail can not restart to download mode a few times. Keep trying, use different usb ports restart computer, try again, restart phone to download mode. I must have got that message 50 times then all of a sudden it worked. Its a pain but see how it goes. There is another way but it is a pain and involves lots of setup.
Be sure to download the right dll and tot files for your model.

Thanks. I have tried few more times and re downloaded files. I have got a little further. 94%
I now have a Factory reset status big red number 2. not 3. I'm only on my 15th try so i'll keep going. thanks for the input.
Return it. You have a hardware problem that no amount firmware flashes will cure.

This will fix your RED 2. I had the same issue.... basically after you load the .dll and the .tot file, in the lower left corner select BOARD DL instead of usb and after it flashes you'll end up at a screen, click on the "yes" then hold the Power button and tap "Normal" on the screen, it'll reboot and your phone is now fixed. No red 2.

I had identical issues on my G2. I had to persevere with firmware flashes to get rid of root. That was simply so that I could return it under warranty. Believe me this is a hardware issue that will persevere through whatever firmware you flash. Your motherboard needs to be replaced. If you are not rooted I would return it now. If you are rooted then you need to carry on until it shows unrooted in the box at the bottom of software update screen. Good luck.

I have not rooted it. bought from individual off the street. The box was sealed and battery sealed. Sprint also said that it had clean esn and had never been activated. Sprint is saying that the Demigod crash handler green screen is a crash due to root and will not return.

If your confident it has never been rooted and it is shown as unrooted I would keep on at them. I've no idea about US consumer legislation but I would guess that they need to provide some evidence that you rooted it.

I have everything ready to flash stock firmware. Now my computer isn't recognizing phone. Says device in USB is malfunctioning and isn't recognized. Have reinstalled drivers from lg site, rebooted, different cords, download lg suite and nothing has worked. So frustrated . debugging mode is enabled. Developer enabled. Must be something on phone as other devices work. I am also able to get phone to boot normally the odd time. This is when computer can't see it. Restarting goes to green screen 90% of the time. Never had problems before with drivers and phone being recognized till green screen 2 days ago.
Update to OP situation?
I have only had my G3 since April 2015 bought it from best buy and today I had a green screen tz crash show up with demigod crash handler. I have never attempted to root or anything with this phone. I was wondering if anyone has an update with this situation. Recently updated gmail through play store maybe 2 hours prior to crash.

It's not something you can necessarily view at will or should want to see again. Maybe try a logcat from adb or get a log report from phone recovery to find more info? I personally haven't had the issue happen since I last posted here. Good luck.

[Q] flashed tmo on att d850 HELP!

I just flashed a rom on my d850 and now the screen wont turn on the phone is completely unresponsive I don't know what to do I can't even get the phone to boot some one help me im sure I just bricked the phone..

First, what rom did you flash and how did you flash it?
Try this as well:
Pull the battery, press the power button for a few seconds. Put the battery back in and press the power button again. Pop the battery out a 2nd time and then put it back in. See if it turns on.
If that doesn't work, pull the battery and hook the phone up (without the battery) to a computer and again see if it turns on and shows up in device manager.
Flashing the wrong rom should only result in a non-booting situation. If you have a custom recovery installed, you should be able to still get into that. The d850 has some serious issues with successfully rebooting in general (which can be resolved by the two suggested procedures above), so I would suspect that before worrying about a brick.
Lastly, the d850 requires bumped ROMs to get by the locked bootloader. The d851 (T-Mobile version) does not have a locked bootloader, so the roms are not bumped and will of course fail to boot.
Once you get back into recovery, just wipe all partitions except for internal storage/sd card and install a correct rom.

When you say you got the phone on, what do you mean?
If it is on and showing up as a phone in Windows, why not just use the LG recovery tool and flash back to stock, then start over?

Give the lg firmware flash and recovery tools a go then. There are several threads on here dealing with unbricking phones that detail what you need to do.

LG G3 Blue Screen

Earlier today I was using my phone I forget what exactly I was doing I think I was using the web browser or opening an app. The phone randomly restarted and after the LG Logo screen appeared I got a blue screen for about 10 to 15 seconds and the screen went off. I pulled the battery to see if that would help but that didn't work. Tried safe mode and even factory reset both times got the blue screen (can get the little menu tho) I then plugged the phone into the computer and initially I could get it into download mode. But after installing the LG drivers, and installing LG Flash Tool I went to flash it back to stock. (My phone has pretty much been stock and unrooted except for the lollipop update. ) When I went to flash the phone screen went blue and the flash tool was unsuccesful at implementing the flash. I also tried the LG Mobile Support Tool. Now intermittently I can get the phone into download mode and get the computer to recognize the phone and LG Flash Tool to the ready stage to flash but after that no luck. Any suggestions? I have not tried fastboot or kdz conversions as I dont think those apply to my problem but I could be wrong

I know this sounds ridiculous but I just did it this weekend and IT WORKS. I pre-heated my oven to 350, removed the motherboard (without sim and/or SD card) and placed it in the middle of my oven on a piece of white paper for EXACTLY 10 minutes. Afterwards, I let it cool and re-assembled. My phone is now working perfectly and I didn't lose any data that was on my phone. I was able to back up my data and am still using it, although I am prepared for it to fail again at any point. I know this sounds absurd but it works. I would post the link but I can't until I've placed 10 posts. I thought this was important enough to share with others and that is why I created an account here. If the moderators look at this please add the link. you can just search Google for "lg g3 blue screen fix oven" and it is the first result right now on forums.androidcentral.com. I'm gonna go ahead and use my phone until it dies again, but for the last 48 hours it has been working flawlessly.

you could do 2 things.. one download KDZ use LGUP flash it and see if it was software related or something went wrong at flash.. if it keeps doing it then it has the bootloop issue.. and need to be sent back for repair....can you provide your first 3 digits of your serial number...?

yes it is its pretty easy... . file is big though... download kdz for you variant.. what android you are using.? MM or were you on stock LP.?
well i think since your phone is from 2015 august. that bootloop was supposed to be fixed by then. but newer phone are still getting hit by the bootloop.. but be aware unlocking the bootloader voids warranty.. some been lucky that phone were repaired some were denied repair..

[PROBLEM] Not Bootloop - Please help [Intesting post]

Good evening everyone,
I come to you guys with a very particular problem. The LG G4 in question is an H815T (Asian variant). Let me clarify right now, it was not bootlooping. This one was getting STUCK at the LG logo, it didn't restart to it multiple times, it just got stuck there one day after turning off by itself. It did go into the download mode, though.
It went into the first part of the recovery, but when you selected that you wanted to factory reset, it got stuck there. The only way to get it out of the logo or the stuck recovery was taking the battery out. Interestingly enough, the phone DID charge at the stuck logo, albeit not so much due to the screen being constantly on at full brightness.
An even more interesting fact... I managed to fix it! I flashed the KDZ corresponding to the latest LP for the H815T, after the process was done, it did bootloop. I found the YouTube video about flashing a certain file to deactivate most of the cores and said "what the hell have I got to lose?"
Flashed the KDZ and.... VOILA! It showed the Recovery Android doing its job at Format Resetting !
Something even crazier... The phone booted into AndroidLP, I was worried about the cores thing, but the phone seemed to work at full speed... I was surprised to run HWmonitor and notice that all of the cores were active. The phone was fully working!!! Or so I thought... Now I have TWO problems:
I cannot update to MM. If I try to update from the phone itself (because it does say there's a new version available) I go back to being stuck at the LG logo.
When I make a call the screen goes off... nothing I do will turn it on, and if the other person does not hang up, the phone will remain locked. However, if I plug in a headset everything works normally.
Is there anything I can do about these two problems? Please, leave your comments and questions, I think this phone is pretty weird and I found nothing else like it on YouTube or here on XDA.
Take care :good:!
Idk for the call but for the mm you could try using something like lg mobile update tool... Something like that.
Be warned cuz i dont know if it will bootloop.

Interestingly enough, the phone DID charge at the stuck logo, albeit not so much due to the screen being constantly on at full brightness.
An even more interesting fact... I managed to fix it! I flashed the KDZ corresponding to the latest LP for the H815T, after the process was done, it did bootloop. I found the YouTube video about flashing a certain file to deactivate most of the cores and said "what the hell have I got to lose?"
Flashed the KDZ and.... VOILA! It showed the Recovery Android doing its job at Format Resetting !
Something even crazier... The phone booted into AndroidLP, I was worried about the cores thing, but the phone seemed to work at full speed... I was surprised to run HWmonitor and notice that all of the cores were active. The phone was fully working!!! Or so I thought... Now I have TWO problems:
I cannot update to MM. If I try to update from the phone itself (because it does say there's a new version available) I go back to being stuck at the LG logo.
When I make a call the screen goes off... nothing I do will turn it on, and if the other person does not hang up, the phone will remain locked. However, if I plug in a headset everything works normally.
Is there anything I can do about these two problems? Please, leave your comments and questions, I think this phone is pretty weird and I found nothing else like it on YouTube or here on XDA.
Take care :good:!

Got it! The sensors thing was definitely it for the screen problem. I also read this is very common with many screen protectors in 5.1.
Do you have any ideas regarding the issue updating to MM?

All good, Willy! Even is you're stuck at the LG logo, take your battery out, or it back in BUT DON'T TURN IT ON... Instead, try to access DOWNLOAD MODE. If you're able to do it, you can flash any KDZ you want, but be careful.

Yes ur right using a heavy screen protector will block all the sensors so ya try removing it... No issues in MM u can try OTA through wifi
