NE4 MODEM

HI why when I change rom (official or custom ) the base band modem did not change i was on sami nd6 rom with NC2 base band and flashed
new NE4 with NE2 base band SINGAPOUR XSP ROM but after flashing modem remained on NC2 why does it occured ? and how can i solve the problem it is daily problem after any rom flashing from old base band to new one also i need a site address which distributes latest modems for example new NE2.
MANY THANKS
May be due to the way you flashed.
How did you flash the custom rom? Via custom recovery or Odin?
I FLASHED OFFICIAL ROM AS NORMAL WAY BY ODIN RESULT=NO MODEM UPDATE THEN FLASHED CUSTOM ROM BY TWRP RECOVERY
(FLASHED :Mix Rom N9005DXUENE4[N9005 - NE4 THEN FLASHED [05/16][ROM][N9005] XXUENE4 4.4.2 Multi CSC DPI, Ultimate V3 452 Mo BY RAYMAN) MODEM DID NOT UPDATED

Flashing new modem and bootloader

I'm on Towelrooted stock 4.4.2 on N9005.
Is it possible to flash only modem N9005XXUGNJ2 and bootloader N9005XXUGBOA5 from Lollipop without upgrading the firmware, and will it have any advantages over the stock Kitkat modem and bootloader?

Baseband and modem

So let's keep this short.
I want to revert to 4.4.4 stock firmware, coming from SimplRom (lollipop).
So before I flashed SimplRom I had to flash a different baseband and a different modem (BOC3 baseband&modem I believe).
Now I want to revert back to 4.4.4 stock firmware, do I have to flash a different baseband and modem BEFORE I can flash the firmware? Or can I just flash it right away with the BOC3 baseband and modem.
Thanks for everyone helping!

Just choose your stock version for your country in order to avoide the CSC problems, make a backup and flash back via Odin. Good Luck.

modem note 4 for x-note rom

Hi,
I want to flash the x-note rom but I need the new modem and bootloader but the links are broken. Will flashing this stock firmware do the trick? PDA N910FXXU1BOC5
CSC N910FPRO1BOC1
5.0.1 firmware for note 4
Or does someone have a link for the NK4 modem and bootloader?
Thanks!

How To Update Lolipop Bootloader to Marshmallow SM-G900F?

I am trying to update my bootloader from Lollipop G900FXXUU1BOD3 on my galaxy s5 using ODIN V3.12.3, to MARSHMALLOW Bootloader so I can flash a MM rom - Where do I find a bootloader and modem that will work with my device on mm in the UK?
sammobile will have the Marshmallow firmware which includes bootloader and modem. Flash that to be on stock unrooted marshmallow. You will lose your custom recovery if you had one before and will need to flash a new one.
If for whatever reason you want only the bootloader and modem - they can be extracted from the zip file via winrar.
