I got this phone about a year ago unlocked and it came with V20a-EUR-XX. I try and update from the update center and it says I am up to date. When I plug it into my PC and go to LG PC suite it says there is a update but it fails to install it and says to remove the USB and battery and restart and then put it back a try again. I have tried this many times and it hasn't worked. The only thing I can think of is to try and update it with .kdz but I am not sure how safe this is and would it mess up my phone. The phone isn't under warranty any more. I haven't modified the phone in any way like rooting it.
So here are my questions
How safe is it to flash a .kdz and is it likely to mess up my phone?
Do you have any other suggestions?
It is safe as updating the phone the official way. You have nothing to be afraid. Download the latest v30n marshmallow kdz file and flash away. no reason to stay on lolipop. Follow the instructions and make sure you do a full factory reset after.
Tutorial
do you have a link to a good tutorial which guides through the whole process of flashing

So I wanted to root my phone using stump. But with the new Lollipop update or something it is patched. To get around this I found out you can use LGFlashtool to go back to an older firmware and from there be able to root. So I followed a guide on using the flash tool. Everything went great until it finished but I got the Factory Reset Status 2 code. I quickly found out the solution is to use Board DL instead of Upgrade DL in flash tool. When I went back through the steps I found out my phone will no longer enter download mode. No matter what I try, USB ports, Upgrade or Board DL mode, restarting my computer and phone multiple times. Any suggestions on how to fix this?

use http://forum.xda-developers.com/lg-g3/general/d855-one-click-root-twrp-recovery-t3072767 to root on LP. stump is an outdated tool.
don't want twrp? just use http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951
with the download mode issues, try flashing a new rom/software with twrp. that'll reinstall the download mode partition (laf.img i think) and then you'll be able to get back into download mode.
So I rooted my phone by installing the rooted 13b img. And went to install xposed framework and apk. I completed all the steps found here (http://forum.xda-developers.com/g4/themes-apps/guide-installing-xposed-locked-t3181593), and now it is stuck on the android logo....suggestions on what do do from here?
A little more detail: After completing steps verbatim, it would fail to install framework. I then read somewhere else that you need to uncheck not only auto mount but the mount option, as well. I tried that and it seemed like it must have worked as it didn't immediately fail and reboot. However, it got stuck on the android logo and after an hour or so I realized there was problem. I have pulled the battery and rebooted several times. I can boot into download mode, but cannot get it to fully boot. Since I could get it into DL mode, I used LGUP to install the 24C MM update (as I didn't have the 13B on my computer). But the result is the same...stuck on the Verizon logo even after a successful install of 24C.
Is this a case of the hardware failure that others are experiencing or is this software related? I see a lot of people with bootloop issues and mine seems to be similar but different. Mine does get past the LG screen to the next screen, but even installing a stock kdz doesn't seem to help...
UPDATE:
Well I downloaded the stock 13B kdz and flashed it via LGUP and it somehow managed to boot. It looked like it was going to be stuck on the Verizon landing page but after about 10 seconds or so it completed boot up. I have now installed the rooted 13B image and made a backup img. I might try again to install xposed framework - fingers crossed it doesn't screw up this time...
Use hyleton's 'LG G4 Stock Firmware (Go Back to Stock) KDZ & TOT Method' that uses LGFlashTool2014.exe and do a CSE Flash - this will wipe all your data though

Thanks, I'll look into that. I was hoping that using LGUP to reflash to stock would do it...but I guess I have to remove whatever the flash tool put on my phone when trying to install the xposed framework...
The phone automatically started to download an update (even though it was not set to do so) and upon resetting became stuck on a black screen with the notification lights blinking blue and red. I can restart the phone but once I do so the update automatically begins to start downloading the update again; even when I put the phone into airplane mode and disable wifi. I have tried to do a factory reset but that just makes the screen go black and the blue/red notification lights start to blink
I have no installed any custom roms or the like; I just use Kingroot in an attempt to get rid of as much bloatware as possible.
Is their some way of stopping the update from running whenever I boot up the phone so that I don't need to completely wipe everything and loose all my data?
People love to get update specially in case of D850 we get an update and you want to get rid of it. Why don't you simply, first, unroot it. Then get update and enjoy the new features.
By doing so you will also get the (maybe) final update for LG G3 on your d850 variant...

I can't unroot it at this point. I can't even do factory reset. I've tried the method using the LG Flash tool and the LG PC suite but neither works.
Can you explain what actually happens when you try to unroot and go back to stock. Is there any problem with download mode or LG flash tool show some errors while returning back to stock. If yes or no please explain in details

When attempting to use LG Flash too I get "model information check fail" after hitting start and reconnecting the phone
Try doing the process on another PC. Same error also happened to me while unrooting on my windows 10 laptop. Then i tried on other windows 7 pc and it was fixed. You can try for that (if didn't),
Hi,
I have the Verizon LG G4 model. My initial G4 was replaced by LG a few months ago and now this phone is bootlooping as well.
I have tried the Safe Mode, the Factory Reset option in the recovery menu but nothing works. I somehow managed to *ONLY ONCE* normally boot into the phone but it went to bootlooping after a few seconds of normal operation.
I *MUST* wipe the device clean before I send it to LG so I thought I'll try flashing the firmware.
I saw many guides but if someone can direct me to the one specifically for the Verizon model, that would be awesome! Also there seems to be a lot of tutorials but I don't know which ones the most recent.
Also, I went to the download mode and it says 633A B71 modified on the bottom. Is there a specific firmware file I should be downloading? I am downloading the VS98611A_06.kdz from

dont flash it yet.. first make sure what antirollback you are on.. ihave no idea about verizon.. if antirollback is higher youll brick phone...
the oldest firmware must be lollipop and maybe the second one too or marsh mallow.. dont flash it untill you know about antirollback and what version to flash.. or you may brick your pghone ask in the verizon thread.

SO I checked the last update from Verizon was the VS98626A version. So I downloaded VS98626A_00_0615_ARB02.kdz and started the flashing process via LGUP. Everything went smoothly, the phone showed progress and said the firmware was being flashed until it had to reboot the phone. When it reboots, the phone still goes back into boot loop mode.
Any ideas on how to fix this??

Then you have the bootloop hardware problem. you need to send it back for repair to verizon or LG USA..
Hello to all of you,
Thanks in advance for any help you can provide.
I bought second hand a LG G4 H815 with CyanogenMod 14 already installed on it.
Everything was fine until I installed my Ebanking apps, that would not function with an unlocked bootloader. I needed to return to a clean factory safe state...
It was the second time I flashed a rom in my whole life, the first one was a Galaxy S plus years ago.
I followed all the instructions for the KDZ flash in this tutorial but I stumbled upon a "Upgrade stopped due to error" in LG flash tool.
I retried 3 or 4 times but with no luck. I verified that the ROM was correct for my model and it was. European and all...
I tried LGUP but my phone is unknown ( at least it's detected)...
I read some posts and told myself "I probably have messed up something, let's try it again with a fresh thing"... I clicked on the factory reset button and carried on.
There the phone booted on TWRP (That i didn't know existed before this). As I explored the menus with a TWRP google search on the computer, I began to realize that the factory reset was maybe a bad thing to do with a custom rom. I tried to reboot but I always end up booting on TWRP.
I re-tried to flash in download mode, but with always the "Upgrade stopped due to error".
I also tried to flash directly from TWRP a stock rom. Didn't work.
I was beginning to lose it and tried to flash the CM14 version I had before, juste to have a working phone again, but even this didn't work... I'm stuck with a TWRP phone
I need some help there...

uninstall any drive for g4 from pc and reinstall again and lgup. now reboot phone to download mode when lgup is open first check upgrade opsion and when open kdz check refurbish opsion and start. good luck
Thank you for your answer
Still no luck
Uninstalled drivers
Rebooted PC
Reinstalled the drivers
Still unknown device
The best way to flash stock image is to use official LG Bridge app. Download it, turn off your phone, connect it to PC while holding volume up button - phone will go into download mode. Then there is option for software restore in LG Bridge but i won't tell u where exactly. If it won't work i would try on another PC. If it won't work maybe you would be able to flash stock image trough send_command but i won't help you with it.
