Lg G3 stuck on LG logo after Android 6. Cant use FlashTool - G3 Q&A, Help & Troubleshooting

Hi,
So someone gave me a LG G3 which he updated to "D85530C_00_0211.kdz". After that the phone stuck in the LG logo and it rarely loads the phone but it freezes. I can barely unlock the phone sometimes but usually it doesn't recognise the touch.
Neither the PC is recognising the phone.
I tried to use LGFlashTool with TOT file but after "READY" when I unplug and plug again it says "Download Fail".
I also tried with the older LGFlashTool using the KDZ but still didn't work. It only worked with the KDZ above, which is the same software and again it is freezing.
LGUP isn't working too.
Any help/suggestions?
P.S.
Maybe I'm using wrong TOT/KDZ?
-The version he updated and also I was able to install is D855
-Under the battery writes "Made in Korea" which may be a Korean phone but Korea doesn't have D855
-I searched on imei.info the IMEI number and it says Carrier Poland.
-I tried using Poland KDZ, Hong-Kong TOT (because they have d855) and Europe TOT(which also has d855)
-The phone is 16GB

I do believe that your board is not of d855. It happened to me a month ago. When I opened the phone.I saw d850 written on my board.so that might be the problem.

It says D855 behind the phone. Also all parts do write D855 and a number near by. So it must be a D855.

LGD855 Changed to LS990 after flashing wrong rom.and wont go back

Hello Everyone I have a problem with my LG G3 which I have bought it recently was working nice but it had KitKat so I wanted to upgrade to lollipop but didn't know that LG G3 had different variant.
I've downloaded a wrong flash (LS990 sprint) and flashed it. so I lost the network and I noticed that the imei has changed. and I don't have the original IMEI of the phone ( the sticker on the back of phone is for D855 16GB not for D855 32GB).so I think its not the original IMEI.
After bricking the phone I've opened it and noticed that it was D855 written on the motherboard.
when trying to flash the original D855 rom it doesn't work (flashed it using the crossDLL method and using the Hex Method By changing D855 to LS990 to make the flash tool think Its LS990) the flash pass on both methods but i'm stuck on LG logo.
send it to some repairing services here in my country but they didn't fix it they thought its sprint so they flashed PrimeGSM but still no network.
I think I should change the IMEI before flashing D855 or something.
please Help me I've looked all over the NET but find no solution to this problem.
If you need more informations ask me. Help me as soon as possible this is the only phone that I have.
Did you ever figure out how to fix this? I have a ls990 which was flashed with PrimeGSM and is now detected as a d855... I have been trying to get this working for the last two days with no luck

Hello
What is the problem that you are facing ?
Is it a network problem or what ?
Primegsm is ported from d855 so i think it will show D855 on any lg g3 that does'nt mean that your phone detected as d855.
Make sure your phone is ls990 or another variant
And which country and carrier ? So i can help you.
I basically have a soft bricked phone - no OS as all. I am in New Zealand running on the Vodafone network.
I was using PrimeGSM and it was working fine but decided to go back to the stock ZV8, when running through LG Flash Tool I noticed Download mode was showing the model as a D855 and would not accept the LS990 DLL - I then made the mistake of using the generic DLL with a D855 image which started a boot loop - then made more mistakes and ended up with no OS and stuck at the LG logo.
At this stage I am able to get to fastboot and use fastboot boot to get into TWRP but cannot do much from there, I also have to use the D855 TWRP image as the LS990 fails with a device tree issue. fastboot will not erase any partitions or flash any images manually. Using terminal in TWRP I am able to browse the partition though but cannot mount the SD card or use adb to push or pull (fails with error closed)
I stuffed up quite a few times along the way but sure I can recover from it since I still have quite a bit of access to the device...
I managed to get my phone going again by following a guide I found in the forum, I am pretty sure it would solve the ops issue as well.
Really quick and easy, I just bridged the points with a needle and copper cable.

G4 H815 now a H818N after Warrenty Claim, Incorrect Software Version now installed

Hello,
Long story short, I have obtained my phone back from repair in Hong Kong (I am located in Australia). Originally the model of G4 was a H815 using software version H81520D_00_0115 I believe from memory. This phone died because of it overheating causing to do a boot loop/stuck on LG Logo screen.
I ended up getting the phone back from Hong Kong, they replaced the mainboard as I thought and now the model of the phone thinks it is a H818N Dual Sim card LG G4 – Running software version V10c-DS1-HQ, which it clearly is not a dual sim card G4 because there is no additional sim card slot. Anyway, phone seems to be working well except the rear camera does not focus (I have had this issue in the past and I resolved the issue by installing the correct software version, eg 20A, 20C, 20D etc.) Trying to update the phone using software update does not reveal any updates. Using LG Bridge reveals an available update for it, it thinks the software version was 20F or 20H not sure, however when it goes to download it does not get past 0% tested on two PC’s.
I have installed the images I have found for the H818N now which are:
Hong Kong H818N10b.kdz (this one worked the best as it didn’t come up with that error message when you reboot if it’s an incompatible kdz image)
India H818N10d_00.kdz
India H818N 10F.kdz
With no success in fixing the rear camera issue. I have not factory reset though as I don’t think it would have much of an impact.
Have tried to loading: H81520D.kdz image but the LGUP utility (which I have been using for the above process) says KDZ file is invalid, I assume this is because it detects the phone as H818.
Does anyone have any suggestions or locations where I could download more images to try like H818N 10A,B,C etc? Or if there is something I should do cause I have had nothing but issues with these phones
Kind regards

Unable To UNROOT LG G3 Korea, Help!

So I bought a rooted LG G3 Korean version (back then i didn't know it was rooted). MODEL d855.
So I looked it up how to unroot it and I found many solutions on how to unroot it, but most of them used LGFlashTool so i went with that method; had everything downloaded but i couldn't find any firmware documents for LG G3 Korean version, so i used different ones such as: European, Hong Kong and many others that i can't remember but all seem to fail to download, all of them stopped at 6% after my failure I decided not to unroot it. But whenever I turn my phone it goes to download mode/firmware update. I have tried holding multiple buttons and taking the battery in and out but nothing seems to work. So now i'm here with my new phone stuck in download mode.
Can anyone help me Unroot it or find a way to exit download mode? I just want my phone back cuz right now it was a waste of money.

what i know is that D855 is the international version, While korean version have a F400 model number with a suffix base on their service provider in Korea (e. F400L for LG U+)
it seems that you need to flash the correct firmware to recover your phone. (it's important to know what model number you have)

My knowledge on phones isn't that great but before i tried to unroot it i looked up how to find my model number and somewhere in the settings i found that it was the D855 and under my battery it says D855 and under that it says made in Korea.
So the Koreans have the F400 but i have the Korean D855, well now i'm totally confused

I bought the phone from a friend so it has no box
If it's a single SIM and not from America, probably H815.

franken phone.. mean phone refurbished by other variant parts.. even they can edit software .. best thing to do is... open up phone and look at the motherboard model.. what ever the motherboard says thats your variant.. you have to phisically see it with your own eyes.. not by looking in software they also edit that..
Wen i checked the mother board, thr was F100L MAIN

The board version is F500L. But the software is of H818. Therefore flash tools would see the phone as H818 and generate invalid file error for any firmware other than H818. So you can recover it installing different firmwares of H818.
You can get its LP 10e here and 10b here.
By the way, how did you upgrade from LP to MM? Means using which tool?

LG G4 F500S bricked, stuck with download mode.

Hello Members,
I will start with a bit of a back story. I ordered a G4 H815 off ebay and the seller information showed it is coming from Hong Kong. Upon arrival, I checked the phone's hardware using CPU-Z and everything seemed fine. The back plate and the about section of the phone both said the phone is H815 model. The android version of the phone was 5.1 so I tried checking for the phone update through ota but it said there are no updates available. So I started searching on the internet for a H815 image file to update to Nougat but I found that Nougat is not available for the 815 model. So I searched and downloaded MM build for the 815 model (H81520b). I flashed it and then later bricked my phone. Sometimes the display stayed blank, sometimes it worked but the radio of the phone never worked. Now after flashing, the phone's about changed the model number to H818. After extensive research and digging through XDA I found that the phone I got is a F500 version refurb (LG or someone did a big scam here). So I downloaded the F500L20c image and flashed it and it fixed my phone.
Later when I checked with imei tracker websites, I found out that my model is F500S and although the L built worked fine for me, the network was very unstable. In order to fix this I downloaded the nougat built for F500S (F500s30b). It flashed perfectly on my phone but I got many errors on startup, so I decided to flash it again but with the refurbish option on the LGUP. The flash started like normal but got stuck at 38% and gives the error 0x2000. After that my phone only boots up to download mode. I tried many times using the refurbish and upgrade option, with the previous and other different kdz's but no success to any of my tries. Any help here would be appreciated.
