Hi,
I just got LG G4 H815T with stock android 5.1 on it.
every thing was working just fine till I decided to force flash Marshmallow and I got the famous error message "NT-Code mcc/mnc...etc"
some people could solve this by editing the "cust_path_mapping.cfg" file using the values in the error message...but in my case I didn't get any values in the error message...just symbols like this [] as well as my Network is not working.
After some research I noticed that this error message and the "cust_path_mapping.cfg" file somehow connected to the NT-Code in the hidden menu (I mean the LG hidden menu which could be accessed by this code *#546368#*815#*) in the hidden menu you you can go in to SVC> Version info... and then you will find NT Code.
the NT code contains long addresses like this: "1","FFF,FFF,FFFFFFFF,FFFFFFFF,11"
And it seems the last two digits refer to the area code, and for fixing the NT Code error message the "cust_path_mapping.cfg" file must contain a code line similar to that one in the NT Code. for example the file should has line like: FFFFFF,11=/cust/OPEN_COM
so the final tow digits in the NT Cod Address is the same in the Line code (which is 11)
So.. My problem is...I still couldn't fix my Netowork issue.. my be this because of my region (Middle East, Cairo). I am not really sure
any one can help me ?? ...especially if you are from the same region so you can send me the line codes for the "cust_path_mapping.cfg" and also the NT Code Address ??
sorry for taking long to explain my problem..I just thought that every detail could help to fix this issue
first of all, H815T is hong kong version
next thing what rom you force flashed on your phone? different phones have different baseband... cross flashing is always risky so you can face such problems ...

Thanks for your replay
First.. I tried the Europe version for marshmallow firmware, but when I faced this issue I tried to go back for lollipop, but nothing changed.
I tried many firmware included the Honk Gong , and Australia because both of them come with H815T version according to this list
http://lg-kdz-firmware.com/lg-g4-firmware/195.html
after all nothing changed and the device still has no service

if you tried europe version first that could be your problem, you flashed fw with different baseband, please describe how are you flashing any fw? with what sw? with what settings?

Ok I will start from the beginning
First I tried to upgrade my phone to Marshmallow, so I went to this link http://storagecow.eu/index.php?dir=Xda/LG+G4/ then opened H815 then went to inside Marshmallow folder and downloaded the Europe version (I don't remember if it was the C or D, but I think I picked the H81520C version )
When I started to flash using LG Flash Tool 2014 the process stopped and it gave me error message (in the flash tool not in the device), and nothing happened to the device of course because this error appeared after checking process for the Kdz file, so every thing was ok.
But I told my self may I can flash the lollipop Firmware for Europe version too, then I'll try to get the OTA update from Marshmallow...and here when every thing started. After successful installing for the Lollipop Europe version (I picked this time the Europe general H815B from the same link) I got the NT Code error message on my device and my device signal is gone, like I don't have operators in my country. I started to research about this error and I noticed then that many people got similar one but with two differences.
The normal error message has values inside it for MCC, MNC and supset the message says "Current Version is not available for user. Can't find matched cust for NT-code mcc/mnc [xxxxx] subset [xx]" and instead of (X) you will find numbers or "F". In my case I got the same message but with empty brackets.
The second deference here is about the network signal, most of people who got the message (with values not empty like me) still have their signal work.. unlike me.
some people could solve the message by editing the "cust_path_mapping" file using the values in the error message as I explained before, but I didn't got any values so I told my self "the new version cause that error and that may be because the different bands"
I tried to search for the default version for my device which was H81510p as I remembered it , but sadly I couldn't find and Firmware versions end with 10P (just to be clear...it's not H815P...but I meant my version was H815T V10P)
I was confused so I choose to try another firmware. I piked this time H815P...that's because H815P used on UAE which considered in the same area here in Egypt and we both use some similar bands, but the problem still there.
In that moment I tried to go back for H815T Firmware with any versions from China (Honk Kong) and Australia, I tried the V10c , V10b and V10h ...and still no improvements.
My last tries was about changing the NT Code inside the hidden menu as I explained too..and I want mention that at the first..when I got the NT Code message with empty brackets..the Address inside NT Code in the hidden menu was like : "0","FFF,FFF,FFFFFFFF,FFFFFFFF,FF"
but when I changed it trying to put my country code like this : "1","FFF,FFF,FFFFFFFF,FFFFFFFF,20" I got the NT Code error message with same values I entered in that long address...so the message changed to "Can't find matched cust for NT-code mcc/mnc [FFFFF] subset [20]"
And here when I noticed the relation between this long address and the NT Code error message besides the cust_path_mapping file
The strange thing is...I couldn't change the address to it's first values..I mean...if I put 0 instead of 1 ...I got "NTCode write error" and nothing changed...but I can easily change the last two digits with any thing and I can go back for example to FF if I want. just the first number won't be changed to 0 again
I think that's all...do you have any conclusions ??
Here is screen shots from my Version info screen....the NT Code is now just "0", because I tried to delete it

After ota update via usb with V20d-eur-xxx on v20e-eur-xxx can no longer via imei check your firmware version.
The phone is manufactured in Hungary, located in Serbia, and not sim lock.
With the old version v10e-eur-hp I update softvare with lg flash tool and everything was nice ok.Telefon and now works just do not understand why I can no longer get when I enter imei stock firmware version.
Updates before he was Suffix: A6HUTN ,and now is A6PSTN.
For now there are no bugs in the work, but to call it a small Bags is that when I enter the mobile Networks menu loaded 3-4 sec, and this happens after update V20A. Why?
So, do you have any problems with phone or ?
It is normal to take few seconds to open network menu. I have that also.

I have no problem with the phone, but I'm interested in why I can no longer unlock through to check the latest version of firmware.
That someone help me? :crying::crying::crying:
I found that my current suffix a6ps from macedonia, and before that was a6hu and that is because the phone is manufactured in Hungary.
Why does it happen and why sites like: devtester, lg-firmware-rom, lg-phone-firmware report IMEI is not valid or no firmware for my IMEI ????:crying:
I was poking around within the settings menu earlier after tapping IMEI SV 5 times under About Phone Status I notice popped up saying SWOV enabled. The only thing I noticed was below IMEI SV appeared a new item - Main software version: V10a-OPT5-SI
Curious if anyone knows what this means or used for?
This one is interesting, as I cannot see anything online about a menu! An SWOV seems to be exclusive to LG based on Software - what it means though is a complete unknown to me.
To be having a SWOV menu, which after a restart you have to activate it, does seem weird when there is no menu to be found... or I am blind and someone will give a clearer answer on this.
*edit*
I might be wrong but SWOV could mean SoftWare O__ Version? I don't know what the O is to save my life but I have a good feeling someone will say what it is xD!
"Main software version " activated under the IMEI SV menu.
for me : " V10a-GLOBAL-COM "
But I do not know what it does.
Just kicking in, even if the thread is really old. But Google didn't find anything so I am here to explain:
SWOV will get activated somehow by clicking several times on an option in telephone-info. Can't explain directly where, but what it does:
SWOV is the "SoftWare Original Version". It displays the version, the telephone was originally shipped with. It's probably hardcoded and can't get changed by software directly. It normally helps to find the correct ROM for your device, if you're curious about. Or where the phone originally was meant to work. For me, it's "V10d-EUR-XX".
For example: "V10a-GLOBAL-COM":
V10d = Shipped with Android version
GLOBAL = Target Operator
COM = (only guessing) Branding?
Anyways: Sorry for gravedigging, but should help some people out I think.
Just unlocked my SWOV accidently now too. Mine says v20d-OPT1-YT
After googling it, I came to this thread.
...Has anyone figured this out yet?

Does it match with the sofware? If not u must had flashed a different csc version of the v20d for e.g TWN ...so the software shows it v20d-twn but originally ur phone v20d-OPT1...its either that or ur phone is repaired or refurbished ...

Yea, your first guess is correct, my handset is orignally v20d-OPT1-YT but I am using your latest v20d-twn because my security patch was last updated in January. Haven't had any updates since my MM update :\

H815P here...
On H815v10e after enabling SWOV menu new option appeared under Developer Options - Enable OEM Unlock. Can I now unlock and relock bootloader in a Nexus way without .bin from LG? It's very interesting.
Mine says V20i-OPT1-HQ
I bought mine new btw
SVOW menu
I also unlocked this on my LG K9. For me it says Vlli-LAO-SI.
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 !!!!
HTML:
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

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...?

Hi guys, I'm having a problem with lg g4 h815t. When I bought this device it was rooted and the update center was disabled. So I thought how would I update this phone, So I decided to flash stock kdz on this device. Even Downloaded a H815T10B.kdz file from storagecow but when I flashed it was giving me error that "couldn't match mmc......." and when I checked the hardware info it shows me H815 instead of H815T I checked my IMEI through the lg stock kdz link it shows me H815T and buyer as HKG (Hong Kong) and another issue which is main issue is now I can't connect to network because when I try to search for network it says "error while searching for network" and when I press on automatic reg then it says "cannot connect to the network" Although other phones works fine in my area but this one gave me a bad impression I have one phone right now So I can't make any call or text to any one......
Please help me or give me some suggestion to fix this problem
at the time when I was flashing stock rom I didn't make a backup of rooted rom so that's was my stupidity......
By the way now I'm on MM V20e-HKG-XX but the problem remains same as above
have you solved the problem?
any progress ? are fix it ?
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.

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.
