Just wondering if it matters which KDZ file you install into your device or not? I've seen so many people flashing 10L in the past few days, posting links to the cdsmg download, some are international, some are eur, some are for 32GB or 16GB variants. How do I know which one will work with my phone without actually trying it? I've checked on the website where you type your imei number and it says latest version for me is 10J
Note : Do it at your own risk , i am not responsible to any damage you do to your device!!!!
with that being said let's cut to the chase
long story short i got a G4 H815p from South Africa about 3 days ago , it was running on lollipop and i decided to update it to Marshmallow , after reading few thread here on XDA i decided to flash a H815 KDZ seeing people in said thread said it was fine to do so ( and there was/isn't any Marshmallow kdz from South Africa ). I used LGUP and updated to marshmallow and once the device booted and was greeted with the error message Error current version is not available for user can't find matched cust for NT code .
At this point i must admit i was a little bit annoyed and i tried to find a way to get rid of that error message and unfortunately it looked like rooting ( which is not possible on the H815p cos of the lock bootloader) the device and deleting/editing the cust.prop file or finding a kdz that matched my regions were the only way out of my predicament. At that point i remembered facing the same issue some times back when i was using a G2 so with the help of XDA and Google i came up with a fix e for my Device but this Should also work on other H815p
Before you proceed you check out this thread . it has info about LG G3 NT CODE and seems the G3 Code are about the same as the G4 ones
THE NT CODE YOU ARE GOING TO APPLY MUST MATCH YOUR KDZ REGION !!!!

http://forum.xda-developers.com/lg-g3/general/how-to-change-region-t2904951
step one
Know which region your Marshmallow kdz that you flashed is from ( in my case it is the Europe H81520C_00_1218.kdz , got it from http://storagecow.eu/index.php?dir=Xda/LG+G4/H815/Marshmallow+6.0/
step two
Enter LG G4 hidden menu using the correct code for your device . My device the code on marshmallow is *#546368#*815#*, i believe it is the same for all H815P got it from here http://forum.xda-developers.com/showpost.php?p=64142393&postcount=79
step 3
Apply code
enter hidden menu
navigate to SVC menu
Navigate to Version info
Navigate to NT Code , Make a backup of your current code and save it on your sd card just in case ( a screen shot will suffice ) and apply the code from you region , close then reboot your device and voila
Pictures s attached to the post to illustrate what was my NT Code before the fix and what it is after now after the fixI tested the phone for 24 hours after applying the fix and everything work as it should , no network issues , calls, sms ,mms. wifi , bluetooth,Gps all work as they should

which device and firmware have you tried this on? i did this on my South African G4 H815P with the 20C European KDZ and till now i haven't encountered any issue ( i even went from the 20c kdz to the 20d kdz using LGUP and didn't have to do the whole process again)

rooted G4 H815P ??? you don't need this process if you're rooted.. go to root folder , delete cust folder, reboot devices.

I did it also..just delete the cust folder. But if you choose like Genisys Rom you dont have that problem..
Many thanks. This method works for me. I've changed nt code from Poland P4 network provider to open Europe. Flashed V20D Firmware and everything works flawlessly .

Worked flawlessly on v29a H815, Applied NT code through hidden menu and "NT Code Write OK" Restated and voila..
Thanks.
I changed following in hidden menu NT Code, changed as below NT Codes with respect to firmware region... Rebooted after confirmation "NT Code Write OK" message.
V29a Firmware NT Code:
"1","FFF,FFF,FFFFFFFF,FFFFFFFF,11"
V20h Firmware NT Code:
"1","FFF,FFF,FFFFFFFF,FFFFFFFF,51"
Checked in both above firmwares..Worked flawlessly on my h818p...No more annoying message on every boot.
Software Version in about/ settings also changed to region exp. 20h-DS2-XX to 20h-ESA-XX upon reboot.
Is DS2 appears when cust mismatch...?

How you could did it?
When I try to change NTCODE in Service Menu, I always get "NTCODE WRITE ERROR" message. Is your bootloader unlocked?
Whats the firmware ver. you are trying this on..?
i also have a h815 ... locked bootloader
whenever the phone is rebooted i get an error message saying 'current version is not available for user. Can't find mathed cust for NT-code mcc/mnc[FFFFFF], subset[55]'
i'm planning on selling the device and i wish to do so without that problem
software version is V10c-OPT2-HQ
need help really fast
thanks
Did you try using LGUP to flash to stock?
If you didnt, make sure to use an international KDZ, for example the newly released V20G.
Good Luck
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
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.
