Need help on LG G3 - G3 Q&A, Help & Troubleshooting

So I have a Sprint based LG G3 (LS990) and trying downgrading it to stock firmware on my desktop. However, after following all the steps, it kept saying failed; USB port open. Now I noticed the first screen on the LG Flash Tool called DBMS. I wasnt exactly sure which button to select at first, so I chose the first one. Am I supposed to be selecting China or others?

[Q] LG G3: Flashing Stock Firmware - Errors

My Question: What Am I Doing Wrong?
The Problem:
Yesterday I decided I wanted to Install MIUI 5 on my LG G3 (AT&T, D850). Not realizing that MIUI Doesn't suppport my phone's variant (D850), I proceeded to accidentally install the International version on my phone. (Which is model D855 and Replaced my kernel with the International variant.) When I tried booting it up, all i got was 10 Minutes of the "LG" logo, then a Kernel Panic.
Not worrying about it too much, I knew i had all the tools necessary to Re-Flash stock Firmware.
Wrong.
When I tried re-installing the D850 firmware, I got "Download Failed."
Still not too worried, I decided to download the International Version .tot file, and try flashing that.
This time I got further, but After it reached 6%, I got "Download Failed" again because of a "Partition Change Fa..." (It's cut off, But i'm assuming that last word is 'Fail')
((This "Download Failed" came just after "LAF: Bin_User_mode", If that helps in any way.))
I have no idea what to do. I tried uisng the .kdz Method also, but It failed and then I realized that I was using the LG G2's .KDZ File. Is it worth downloading the .KDZ File for the LG G3 and Trying again?
Please Help!
Thanks! :good:

LG G4 not working with LG Bridge

Hello all. Not been on XDA for a while; but I hope you can help me. I have an LG G4, which I just received yesterday from Vodafone UK. I tried to connect it to LG Bridge today to check for updates, but the Bridge would not work with the phone. The phone name showed up in the bottom left corner of the Bridge screen. It said something about it cannot work with this phone at this time; please try later. I had installed the drivers for the phone, and switched debugging on and off a on again. I tried it with usb set to all the different options; but nothing worked. Have you got any ideas as to how to get this working correctly?
what drivers did you install?
The official WHQL_Ver_4.0.4 from the LG site? (can't link it)
Worked with LG Bridge for me on my stock H815.

I had LG Bridge switched on, and I had the LG drivers from the website. I think the LG Bridge is incompatible with Windows 10, which is what my laptop runs on. However, I did manage to get both my husband's phone, and mine, updated to Marshmallow. I used a program from here on XDA called LGUP, and found the relevant kdz file to run the LGUP program. The phones are both on stock Marshmallow now, with no sign of the Vodafone boot menu. I ran LGUP as an update, so that I was able to keep all my apps, files, etc, as they were before.
Thank you for your help, @Yuuseki, I appreciate it.

Success after supersu bootlooping and non recognized usb on g4

Like a lot of people I have the eu version of the h815 and managed to bootloop it after following the garbage methods online for rooting .. I came here for help and found all the methods listed... lg up, lg flashtool 2014 etc.. the problem was that my phone just wasn't recognized by the computer, it charged well but that was it, lg bridge, lg up, lg flashtool.. none could find my phone.. I thought I was doomed to a soft bricked paperweight and even began contemplating the hundreds of pounds needed to purchase a new phone.. however after hours and hours of tinkering I cracked it and now have a working lg g4 again.
first off download and install lg up dll file
then install lg up but don't open yet
find and make sure u download the correct kdz firmware file ( I needed the h81520d file which I downloaded from storage cow as devtesters didn't work for me)
now head to your computer control panel and delete(uninstall) any lg mobile drivers that you see.
connect your phone through usb into download mode and leave connected
once that's done download the old drivers (4.0.4 I believe) and not the newest 4.1.1 or whatever it is now.
then open lg up and hopefully like me you see your recognized phone.
click upgrade (not refurbish) and click bin.. right of bin is the ... symbol.
hit that, choose your kdz file and voila.. let it work its magic..
DAMN IM HAPPY. HOPE THIS CAN HELP SOME OF YOU LIKE IT DID ME.

LG G4 help to restore to factory ROM (Verizon LGUS991)

Good day, all
I need help to hopefully restore any working ROM to my LG G4.
Album of screenshots: https://imgur.com/a/3afkFbl
The short story is, I originally saw a slightly newer firmware on the LG site https://lg-firmwares.com/. But I may have installed the wrong one since I now cannot get 4G LTE and I now have a 'US Cellular' splash screen at bootup (as opposed to the original LG splash screen). So I got a new LG V20 and it is now having issues. So I decided to try to go back to the LG 4G IF I can get the right firmware on the phone.
I attempted to enable USB debugging, install the LG drivers, DLL and boot into download mode and use the LG UP software to install the firmware US99125a_00_0317.kdz (not SURE if this is the correct firmware or not but I’m frustrated and starting to not care). However, the LG UP software won't recognize my phone (please see screenshots at link below). I also tried the LG Flash Tool and Uppercut (with the request LG UP version) and neither worked (also see screenshots). The phone looks to be kind of messed up when looking at the status section of ‘settings’ and the fact that it won’t connect to 4G LTE and has the ‘us celluar’ splash screen.
Can anyone guide me on how to fix this (hopefully)?

LG G3 D855 EU - Factory Reset Status 2

Hello from Sweden!
I have had an LG G3 for quite a while now just laying around due to issues I ran into with it after unsuccessfully rooting it, those issues specifically was Factory Reset Status 2.
I've been reading around that flashing it with stock firmware can work, and that's something I've tried but haven't seemed to have such success with as I've tried both the KDZ method and TOT method.
With the KDZ method, using the LG Flash Tool 2014 I kept on receiving errors that the tool couldn't communicate with servers and I never seem to run into any success no matter the flash mode I chose (CSE or Normal).
When doing the TOT method, however, I seemed to get a bit further (it felt like at least). When running the LG FlashTool v1.8 I selected manual mode, selected the TOT (LGD855AT-V10e-EUR-16G) and DLL file (LGD855_20140526_LGFLASHv160) I had downloaded for the LG G3 D855, I also made sure that I was using the action mode "UPGRADE DL" and the connection method "USB" in the software.
I click on the yellow arrow to continue and "READY!!" shows up on Port 1 and I then replug the phone and "Waiting for connection" shows up in the box and I wait a few seconds and it begins, but almost instantly ends giving me the error "Model information Check failed!".
Honestly, at this point, I am fully unaware of what to try. I am willing to provide more information if required to get assistance with this, I am willing to try almost anything to get this phone working no matter if I lose all data or not.
I'm thankful for all tips I get provided to attempt to fix this.
