If I buy an S7 Edge from a country with a different CSC, is it possible to download the correct latest firmware from sammobile and flash in Odin in order to get full CSC compatibility with my region? and will that change all CSC aspects, both hardware and software (There are 2 CSC, one for device and for ROM, just for clarification of my question)?
yes, you can change the csc or even rom on the phone to comply with your country. Just make sure that the phone is unlocked.
there is only 1 csc which changes the software ware only. Hardware is not changed as there is nothing that is user changable without disassembling the phone.

Somewhere in all my flashing/wiping, I seem to have lost my CSC.
When I install Phone INFO and go to the CSC Code tab, it now says BTU (it should say SPR).
Can anyone tell me how to download and restore the Sprint CSC on my phone?
In particular, I am looking for one that is compatible with CM12.1 (I'm not 100% sure that the CSC is related to the ROM, so that might be irrelevant, but just in case).
Also, is there a specific Bootloader/Modem that you recommend for CM12.1?
Many thanks

It's irrelevant when you use aosp. For you second question: Yes it comes with the rom.
Long time lurker, first time poster. I want to express my thanks to everyone who is making this community so great.
I've purchased a S7 edge recently and I noticed I have the TPH (Portugal) CSC code. I'd hope to change it to a Belgian CSC. Two things come to mind:
1 - When I scoured the sammobile site for a suitable Belgian firmware, the only one I found was PRO, which seems to be linked to the Proximus carrier, which is different from my carrier. Is it safe to assume that the PRO firmware is the only Belgian firmware around and therefore not limited to be used with other carriers? Or should I opt for a Luxemburg CSC instead?
2 - I have been looking at the forums for clear instructions on how to perform this, but haven't found this specifically for the S7 (edge). Could someone explain on what I need to do? I'm assuming I just have to download the firmware and use Odin to flash the 4 files, but do i need to set some specific options on Odin before flashing?
Your input is much appreciated.
totally same question. up
This app should let you to change CSC even without root https://play.google.com/store/apps/details?id=com.zigbrick.galaxyregionunlock
The only way to change the CSC on non-rooted devices is flashing the designated CSC file through ODIN. However, there are limits. In case of Belgium I did only find the version for Proximus, too. But the PRO one is a multi-csc file (VFG Germany) and if you flash this you will end up with Vodafone Germany (VD2), a branded rom. Without root that's the only option you have. If you flash LUX then you have LUX which makes me wonder why you even want to change it as TPH is unbranded and you don't gain anything...
Hey Guys !
So, my phones CSC code is DDE which means Deutsche Telekom. Currently Im using Slovak O2 SIM card so i don't think its carrier locked.
Now, I would like to change my CSC to BTU because theres 0 chance Telekom will update their firmware in this century.
So the question is, can this brick my phone if something goes wrong ? I heard stories about deleting IMEI by changing CSC etc.

Download and install Phone INFO from Playstore. Check under the CSC CODE tab which country service codes are available for your specific model. Reference that with Sammobile and download the latest firmware.
(Continue ONLY if you've confirmed you have multi CSC on your device in other words more than one CSC to change to)
You'll notice there are 2 CSC files in the zip downloaded from Sammobile. Flash the one that starts with CSC and NOT the one starting with HOME. Your phone will then factory reset so make sure you've backed it up.
Ps!!! Warning!!!
Changing the CSC / product code on your Samsung device may invalidate the warranty. It may also invalidate the Samsung Knox warranty for Samsung devices
that support Samsung Knox. Furthermore, there is no guarantee that flashing the new firmware will work, even when you flash valid firmware.
In many cases, flashing the same firmware a second, or third, time may work.

Nevermind try it. You'll see the magic. But be careful unless your phone is sm-g930f you may brick it.
I hace a similar problem, phone info says my csc its from BTU (UK) but I'm in Peru, I cannot make calls, How can I flash the correct csc for Peru?
Hi guys,
Sorry I just need a quick answer to this and I can't seem to find a straight answer anywhere. I have a G935F on 3 UK firmware and I want to change the firmware to either BTU or XEU, as the updates are ridiculously slow on this software version. I have read in multiple places that the CSC code is hard coded and cannot be changed, and then other places say this is merely cosmetic and flashing a new firmware will enable you to get OTA updates from the new desired CSC code.
Please can somebody shed some light on this for me, if I flash BTU or XEU will I be able to get updates as normal, and also which is better to flash XEU or BTU. If anybody can advise would either of these packages allow VoLTE and Wifi Calling to work? 3 supports them on the firmware I am currently on, but I was unsure if unbranded firmwares would support this.
Thanks!

Hi if this is of any help i was on Vodafone and decided i didn't want there bloatware on here so i flashed the latest XEU as it was newer than BTU.
When i go into the phone app it shows me what my old csc was and the active one which is xeu you do get updates plus i got WiFi calling enabled still but had to get vodafone to activate it on my account again.
Hi,
I noticed recently that the Galaxy S10(+) and its firmwares are quite similar, if not coming from a network operator.
To illustrate this, I would say for example BTU which is stock UK has the same PDA and CSC numbers than French stock XEF.
How is this possible?
What's more, the phone seems to automatically know which code to use — after flash it will display on the 'About' tab the code related to your country, independently from what country-related S10 firmware you decided to download.
It can't be fooled anymore because as far as I remember you could flash other firmwares with different country codes so that you would sometimes get updates faster.
Or I might be just wrong.
@ThomasM6
Regardless of the branding, the available network bands are similar, if not exact, through Europe, Middle East, Africa, Southeast Asia and Oceania so that a one size fits all approach works on a hardware-level.
This same methodology is in place when it comes to firmware.
To an extent.
To demonstrate my point, I've attached a file called 'product.map' which I've extracted.
(I had to rename it to 'product.txt')
Inside that file you will see almost every major telecom company across EMEA and APAC listed.
It is using this file, alongside a combination of .info. txt., .dat, .xml and others across the operating system, to isolate the Carrier based on the SIM card inserted.
If it does NOT locate the appropriate telecom, it defaults to native country where it was intended to be sold.

A number of users have stated the software now matches the SIM's CSC so flashing the device is no longer necessary.
Some are still having trouble selecting the correct active CSC in a multi CSC firmware
