CSC files modification - Samsung Galaxy S7 Edge Questions and Answers

Hi Folks
Technically, is it possible to modify the CSC files to add /removes features and then flash the same using ODIN. Needless to say KNOX warranty should not get tripped and Rooting should not be a pre-requisite.
I am trying to enable VOLTE for a particular Indian telecom provider Reliance JIO on a USA snapdragon phone. If i install the XAA firmware i will get all the LTE bands enabled that is used by JIO. I was wondering that if i can modify the CSC files then i could add copy all the JIO related parameters from a genuine INS CSC file and modify my current CSC file and then flash using ODIN.
Thanks

Which CSC can I change to? SM-G935F/SM-G935FD

Hey Guys,
Since my phone was purchased from the UAE, VoLTE is disabled. I would like to change the CSC to any that has VolTE & Wifi calling enabled. The "About Phone" section shows my model to be "SM-G935FD" whereas the PhoneINFO app shows it to be "SM-G935F". Are they the same? PhoneINFO also shows my FW & Active CSC to be XSG & available CSC Codes are:
ACR,AFG,AFR,BTC,DKR,DRC,ECT,EGY,KSA,LYS,MAT,MID,MRT,MRU,MTZ,MWD,PAK,SMG,THR,TMC,TUN,TUR,WTL,XFA,XFE,XFM,XFU,XSG.
Im on 6.0.1 and was wondering if I can change it to the following UK Nougat :

or this Indian 6.0.1 at least:

Thank you
If you need VoLTE and WiFi calling. You need to flash INS csc. Backup your data and make a factory reset and wipe cache. This will also fix the CSC as active which provides VoLTE and WiFi calling.

Thanks for the reply, Siva. So I can flash INS even though it's not mentioned under "available CSC Codes" in my phone? If I wanted to get the nougat, can I flash the UK firmware I have mentioned ?
Thank you

[Q] Flashing different CSC file on J320A

Hi
1. Is it possible to flash J320F(or some other J320 modification) CSC file (for example, GER csc) to J320A(AT&T) ?
2. If yes, do I need to find csc file of a version with the same version/gen. of firmware? (AQA1 from J320(non-A) to J320A with AQA1 firm., and not for an example APJ2 of non-at&t to AQA1 at&t)
Is there is another method to change J320A's CSC ?
Thanks
Never messed around but heres our csc for you to inspect

CSC change - TMobile to INU, INS (SM-N910T to use SM-N910G CSC)

I have a Samsung Note-4 (SM-N910T) from T-Mobile USA. It is paid for already 2 years ago and the warranty is also no more.
I wish to use it and India on the Reliance JIO network, the only one offering VoLTE at the moment.
Because the CSC is of T-Mobile it does not pick up the VoLTE and text services information. However, the data services are available meaning the phone sees the network.
I end up using their proprietary program. In the future I want to use VoLTE as that call is better than a program pushing voice on a LTE.
I downloaded the firmwares for Note-4 for USA and India (INU and INS variants SM-N910G CSC with ODD) from SamMobile.
The phones are identical specs with the difference being in the bands, the Indian Note-4 has Band 3,5 and 40. The USA one only has bands 3,5. The other bands are useless to me so I am not mentioning them.
I WANT TO KNOW: How do I extract the CSC files from the INU, INS firmwares and inject them into the T-Mobile USA for mirror I downloaded.
When I downloaded the Firmware MD5 file, there were no separate BL,AP,CP, CSC files in the archive. I am unable to make them (BL,AP,CP and CSC) myself and the Samsung Firmware Maker does to recognize that file type.
Because bands 3 and 5 are there, I believe the VoLTE will work.
I would appreciate help in the operation I wish to perform.
Thread moved to proper forum.

Flashing G950F CSC to G950FD

I have bought a G950FD dual sim S8 from UAE. In order not to have any limitation from service provider in Turkey (like voLTE, voWIFI or SamsungPay) I am planning to flash G950F CSC. Will there be any complications, what do you think?

Let us all know what happens. I'm curious to see these things on an international level.

Are you sure that your Turkish provider doesn't use the same CSC as the UAE CSC? Most G950F/FD's use the multi-CSC and all you need to do is a factory reset, then put your country's SIM in and it will apply that CSC.
Also, G950F/FD are the exact same firmware/CSC

That is exactly what happened, even better my provider recognized the phone as G950F so there was no need to flash CSC at all.

How to change CSC from XAA to TCE?

I bought a S8 + originally from Verizon. Then installed firmware unlocked (SM-G955U1) then the CSC automatically changed to XAA (usa unbranded).
I am currently using it in Mexico with Telcel. Everything works good, samsung pay does work, but I want to active VoLTE and use carrier ID anti spam there's no option to activate that because my CSC is not TCE, the problem is that the firmware is not SM-G955F (exynos version) that includes TCE (telcel México) CSC which allows to go to a specific setting menu to activate volte and ID anti spam.
I'm almost sure it is not possible changing the CSC because proccesor firmware incompatibility Snapdragon (SM-G955U1) and Exynos (SM-G955F).
The question is, can I change the CSC that comes with firmware U to a CSC that is supposed ONLY included in firmware F (exynos) ?
And how to do that?
