LG H815P FiX Can't find matched cust for NT-code mmc/mnc[], subset[]

[touns_j]

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 fix​

I 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

thanks to @YaDr , @JeremyChen

Hi, NT WRITE CODE to me too, every time (rooted LG G4 815P). Any help? Thanks!

NTCODE WRITE ERROR - every time

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)

Hi, NT WRITE CODE to me too, every time (rooted LG G4 815P). Any help? Thanks!

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 .

Thank you very much! Yes, I have a LG G4 (815P) rooted device, and after delete the cust folder, everything looks great now. My best regards :good:

there's no way of "changing your H815tr into a H815p
' , what you can do it manually flash an unbranded H815

there's no way of "changing your H815tr into a H815p, what you can do it manually flash an unbranded H815 on your device using like the newly released 20h uk firmware here http://forum.xda-developers.com/g4/general/kdz-firmware-v20h-united-kingdom-2016-t3396480

Worked flawlessly on v29a H815, Applied NT code through hidden menu and "NT Code Write OK" Restated and voila..
Thanks.

 

[shahper1]

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?

 

[shahper1]

Whats the firmware ver. you are trying this on..?
