What is CSC file doing?

To those who are flashing firmware,
May I know what does the CSC file do? I notice I can flash the firmware CODE and MODEM file with different CSC, looks like my phone is still working.
And different CSC are different in size.
Any idea?

CSC is the Country/Carrier Specific Code (not sure exactly which it is, both kinda make sense). It contains the files for customisation for specific networks, so will have the APN settings, maybe custom ringtones or backgrounds, and can have programs too. Some CSC files contain a lot more than others, hence the file size differences.
Mixing different PDA/PHONE/CSC files is certainly possible, although it might be best not to stray too far on the PDA and PHONE side. The CSC isn't really very important in most cases - at worst you'll probably just have to set up the APN manually.

Thanks for that definition. I am new to Android and very new to Rooting so have been trying to find out why I can't do a backup and the CSC file was a definition I was struggling to find using Google. Just need to find out what XUE is now as Google just tells me it it a Chinese name!.
Thanks again,

XEU is just the csc code for Europe.
Different regions have different codes.

will flashing a european pda and modem with asian csc do harm to the phone?

Nope no harm...

Thanks for the reply. Does that hold true even if the csc is taken from a froyo firmware? Just wanna be sure prior to flashing so i'm asking.

Just to be sure. Csc from asia froyo and pda from gb euro

Will I lose my warranty if I flash with another CSC? I would like to flash to something better, I've found my stock PDA and PHONE files to download but CSC is unavailable ( CSC:I9000GCROJV7). Or Can I somehow extract CSC from my phone to computer?

Of course flashing the phone with Odin makes you lose the warranty on the phone, but sometimes Service Centre don't mind on that if there is a hardware issue. I advise you to read carefully guides before starting any operation

Can anyone explain what a Multi-CSC is (in terms of files) ? Can there be many types of Multi-CSCs also I mean, one Multi-CSCs that covers a certain geography/market & another CSC that covers another geography/market ?

I know I'm 2 months behind on my reply, but your question has been *partially* answered.
CSC stands for "Consumer Software Customization" and can cause loss of service if it is set wrong. In the US, there are both GSM and CDMA networks and are carrier specific. The radio channels are also carrier specific, so there might even be a differemt CSC between commercial and corporate users. Flashing a CSC for AT&T on a Verizon branded phone will (more than likely) break the functionality of LTE capability,calling, text messages, and data usage.
I flashed an outdated ROM on my Note 3 last year and I couldn't access my carrier network until I flashed back to JasmineROM.
Long story short, unless you are changing carrier networks and have a carrier branded phone, it's probably wise not to mess with it. Unlocked SIM card users (NOT unlocked bootloader or rooted; completely different) may get away with flashing the international firmware, but I don't know for sure.

[Q] Can someone explain technically what happen if a different CSC is used?

Hi,
I have tried to look around for an answer to this Q, but none has given a technical answer, just a general "do it, don t worry , don t do it...".As anyone knows, every update Samsung releases is released by Countries or "areas". The CSC defines these areas and throu the correct code it is pushed via kies only to the given Countries.. Now, I wonder what happen if I flash thru Odin a new FW ( say the newest 2.2.1 JS3 that is made by a single tar file including a CSC XEU) to a NON XEU Samsung, my case being italian is ITV ...I know that I should have a working phone, 2.2.1 update , in italian language yet with a CSC XEU....so what? what are the tecnical implications or changes I have? different setting to radio? Swipe not working? Wrong APN...??? DIFFERENT IMEI??the typical known things are that I will not be probably be able to connect thru Kies, and lost my warranty . But ...what else? If these are the only things, If I have to worry about my warranty, then I can always reflash wth the original ITV FW....mmmh, anyone can explain me the associated risks/ pros and cons? thanx a lot

Essentially its the networks local to that CSC .
ITV csc is going to give you your local networks .
SER csc is giving Russian networks
XEU is UK and Ireland
You flash a CSC for your area .
jje

Thanx JJE....but, if I understand well, flashing a FW with a different CSC would NOT give me my local networks and therefore ( this is the point) I should not be able to find them...well, this it seems not to be true. Many users living in different countries have flashed the first 2.2.1 JPY XEU appeared on dec 2010 yet I think they have been able to connect to their networks...I mean, not sure about that biut I guess that if they could have not , they would have noticed....

All a CSC is, is a bunch of text files that tell Android what to set as default when there is no data partition.
It contains your default APN. As well as the default "home" bookmark in the browser, and any other bookmarks that may show up by default. It contains default settings for keyboards, like languages and if click sounds/vibrations are on or off.
Just extract one of the csc *.tar files and open all the files in WordPad or something similar. There's nothing there that can possibly hurt your phone if you go to another CSC. It's JUST settings that can be changed and saved when you're booted into android and have a data partition.

[Q] Manually change CSC

Hi to everyone!.
Like the title says, I want to manually change the CSC of a i9000b to a unlisted one, so after a bit of search I've found this two directories that contains CSC:
-/system/csc/sales_code.dat
-/efs/imei/mps_code.dat
Editing the first one (sales_code.dat) does nothing, and I've fear to edit the second one (mps_code.dat in efs).
So there is any risk of edditing only 'mps_code.dat' and don't mess IMEI number or anything else?
This will change the phone CSC?
With the retail CSC on the phone, I can get a retail firmware update from Kies?
Thanks to all

Have you tried *#272*your imei#
This will give you a selection of csc codes to choose from. If you do pick any of them it will instantly factory reset your phone with no warning.
If you have tried this please explain what you mean by "unlisted" csc code. You mean one that does not have network firmware? If so then CSC will not change your firmware you will have to install another firmware for that (an unbranded firmware).
If you wish to remove the network lock this will not work, you need to get the unlock code, search for that or call your provider and they will do it for you at a cost.
Also i would not advise changing anything in the efs folder, as you mentioned, it could mess up your imei...
Let me know if that helps..

Hi , the point is that I don't have multi CSC (I can't change it by *#272*...*) so I've to change to a 'unlisted' one.
I never say that that will change my firmware, the idea is that with the CSC changed to a retail one, Kies will enable my to update a Retail Firmware to the phone. (or maybe not?, that's the point)

Unfortunately that will not work. If you want retail firmware (unlocked/ non-carrier/ no-network firmware?) then you will have to install that first. If you search for it in the general section you should be able to find it, search for stock firmware. Also you can get it via Sammobile.com Click on firmwares tab (underneath the news link at the top) and follow till you find the stock firmware for you region.

Why it will not work? Can you explain? thanks

CSC i think stands for "country specific code". However even if it doesn't it is a relation to what the code is.
The code identifies the region/country you are in. For example I'm in the UK therefore i have a CSC code of XEU this is a code that is for the EU. Which could affect the signal performance, i may get better or i may get worse or i may get no signal at all. Also I may get 2g signal but no data connection etc. It could also cause issues with receiving SMS messages if the correct or compatible code is not used. For example the time and date may be incorrect, the messages in the list may be out of order (the message you sent is below the reply received).
Therefore it affects your relationship with the carrier and is usually better optimised for your country/region. When you connect to Kies the CSC code is taken into account but so is the actual firmware. By changing the CSC you do not change the firmware to stock firmware it remains carrier/network customised. As such this will be detected by Kies when you connect. If you change the CSC and then connect to Kies I think it does not accept your firmware installed as original authorised firmware, as my CSC was set to KOR after returning from a software reflash from an authorised repair centre. However this may be different for you and I cannot guarantee what will happen but to my knowledge this will not work.
As i mentioned you will need to flash stock firmware yourself or go to a non-carrier authorised repair centre (I used carphone warehouse in the UK) and ask for a software update. You can find your nearest authorised repair centre on the samsung website.
Also if you search you will probably find a better explanation to what CSC is and understand why it won't work, I did my best hope it makes sense

I get your point , instead of CSC I think I was trying to mean Product Code.
By edditing Product Code (and a valid Software revision?) can I cheat Kies to get me a retail update?. Like the old method of editing the registry but on the phone.

Unfortunately I'm not experienced enough to give you an answer on that. But I would think that it would take more than that to trick Kies.
What is holding you back from going to an authorised repair centre or a just using Odin? (Using Odin is actually quite simple provided you follow the steps and have the right files, which Sammobile does provide). You will be left with the retail firmware and Kies will recognise you and provide any updates available.

The problem is that I couldn't find the firmware on samfirmware or any other site. I've found this just now http://forum.xda-developers.com/showthread.php?t=1032437, so maybe I can finally get the official upgrade.

Sorry to bring this back up, but my CSC is blank too.
I typed in the *#272*your imei# and the option for sales code VOD came up. I selected it, but it tells me that "Must be THREE chars". VOD is three characters. Why cant I select it???

Hi
I live in holland, so i don't have the 4.0.4 update yet. If i change my CSC, does it change region so i can download the 4.0.4 update?
thanks in advance

Exynos CSC swap - T-Mobile Wifi Calling and VoLTE adventure

*EDIT 2018 January so you don't need to read 7 billion pages of this thread*
It took 3 months but I finally figured out how to get T-Mobile Wifi Calling to work properly on the N950N's firmware.
Please see this thread for the patch updates: [MOD] Exynos T-Mobile CSC Wifi Calling, VoLTE etc for N950N / N950F
Trying to get wifi calling working with my SM-N950N (South Korean model from SK Telecom) to work on T-Mobile here, and as I understand it we need the proper CSC flashed.
Now, I probably am just overlooking something (hopefully) but can't seem to get this phone to take. I downloaded both firmwares from Sammobile (paid for a month premium membership),
pulled the cache.img.ext4 file out of the TMB CSC tar.md5,
pulled the PIT file out of the Korean CSC .tar.md5,
in the PIT changed the file name from cache.img (original) to match the TMB file name cache.img.ext4 and adjusted the partition size and block value for the CSC partition,
adjusted the block values for the 4 partitions listed after it to account for the double sized new one
built a new .tar.md5 with the modified Korean CSC PIT file, the TMB cache.img.ext4 file, and the omr.img file that was in the original Korean CSC .tar.md5
I tried this with and without Re-partition checked, tried adding the remaining files into each field (BL, AP, etc) along with it, and tried an old 1.87 version of Odin (mainly trying to use 3.12.7 from Sammobile).
No matter what I try Odin errors immediately saying that repartitioning failed.
Any suggestions as to how I can get this to flash?

following, Also have the South Korea version and i want to Change Csc and debrand it

been poking around with a few things at work today, was able to get some settings changed by granting an app secure write permissions over ADB but I am even more convinced that the CSC needs to be flashed somehow. I got into some currently-hidden menus with settings for IMS, VoLTE, and WiFi calling but some of them crash if you try to enable it, others are disabled, and others pretend to be doing something before reverting back to 'off'.

I'll look into this more tomorrow and ask on Sammobile to broaden the knowledge pool.

On the SM-N950N you can only flash -N- firmware!
Don't mess around with other FW's!

I know from experience and XDA that this is false. I'm not sure if you're aware of what we do here on XDA but flashing different and custom firmware is the name of the game.
If you're afraid of that, best stick to your OEM updates and keep misinformed comments to yourself.
Can anyone who knows about this stuff think of what step i may be missing here? I don't understand why it won't repartition in Odin, but as far as I can tell this should be working since i adjusted the sizes in the PIT file to match the larger CSC partition.

Well sir, you are replying to my thread with false information. I am working to flash a USA T-Mobile CSC to my Korean model phone. It can be done, and I am asking for people who know more about this than I currently do for suggestions.
You obviously don't know at least more than me, since you felt it prudent ti post your false claim that only firmware created by Samsung for a specific model can be flashed to that model. I respect your right do do whatever you want with your phone, but your words are not true and you're not helping anyone by posting them in my thread here.
I never said I cared about KNOX (which I don't, I have a phone sold in a country on the other side of Earth, and I am on XDA which generally means I prefer modifying my devices).
Thank you and good day, but please don't post false information. People can flash whatever they want to their phones, regardless of what you or Samsung might wish.

Don't try to be smart...!

It might have something to do with different processor. The US CSC is for snapdragon and the SK CSC for the Exynos. Just a thought.

Yeah, I had suspected that but on the S8 forums someone specifically said that CSC were universal and that you can switch between them on Snapdragon and Exynos models.
In any case, I did finally get it to work via flash able zip but also learned that the CSC on these latest flagship models is just a folder /system/csc/ that you can overwrite the entire contents of with a file manager once you have root.
After that and a reboot, phone info apps now show the correct available CSCs but still show SKC as the loaded one so I'm close but 1 step away. The IMS settings app has all the T-mobile data now, but I still can't confirm VoLTE or wifi calling and that settings app shows no IMS profiles registered still.
Getting close, I just wish one of these smart developers would give me a hand so I knew more what I was doing :good:

per this thread: https://forum.xda-developers.com/showpost.php?p=71192951&postcount=5226
I fixed the folder and file permissions, as well as replaced the OMC folder contents to match a T-Mobile phone as well.
That REALLY made it angry. upon reboot I couldn't get any cell service and it said there was no SIM card installed, on top of other Korean provider apps now appearing (instead of just the SK Telecom apps that were initially visible).
So I'm guessing that these phones go by the OMC rather than CSC but since replacing that made it not work at all I'm a little unsure of how to proceed.
I copied the stock OMC files back over, fixing permissions per that thread, rebooted and now I'm back to where I was before replacing the OMC folder contents. Phone works fine, i get fast LTE but still no wifi calling or VoLTE that I can tell, and the IMS is not registering (which is probably the cause of both).

After reading this thread about the S8's: https://forum.xda-developers.com/galaxy-s8+/help/adding-att-volte-wifi-calling-t3599439/page5
I copied the Tmobile OMC files over again, fixed permissions, and edited /efs/imie/mps_code.dat, and changed it to TMB and rebooted. Got the Tmobile boot screen instead of SK Telecom (along with annoying T-jingle sound), but phone app FQs indefinitely, no network service, and I can't view mobile networks. Trying to view more connection settings closes the settings app.
however, Phone Info app now shows Original CSC: TMB, Firmware CSC: XAA, Active CSC: TMB but Product Code, Available CSC Codes, and Mobile Operator are now blank.
Getting really close here, but it seems like there are probably some other files that need to be copied over, and I am not sure what they are. Thinking perhaps stuff to do with the T-Mobile variant's apps/settings apps.
Thoughts?

Good news - almost everything is working thanks to the good folks in the S8 forums per this CSC changer zip: https://forum.xda-developers.com/ga...lashable-csc-selection-v1-1-0-t3636739/page31
On a hunch I tried to just run it and see what happened. After repackaging his zip after replacing the XAA and TMB omc folders within it from those from an SM-N950U T-Mobile ROM, I used my modified version to update to TMB and this time no crashing on bootup, LTE still working, Wifi still working, and as far as I can tell VoLTE is working because it didn't drop me from LTE to 3g when making a voice call, though I do not see a VoLTE icon or any VoLTE menu options still.
Not sure if working: Wifi Calling, as I don't see an icon or menu options either, but running the Tmobile WFC settings app with a shortcut app showed that it was enabled but the toggle is greyed out, but I made a call with mobile data supposedly turned off and WiFi on and it said it was an HD Voice call in the dialer. Oh and the dialer claims to be new and for video calling, but I don't know anyone on Tmobile with video calling to test that out.
If I can confirm that WiFi calling is somehow working then this solves all the problems for us importing Exynos models.

yeah I am trying to find a way to upload it, even after deleting a bunch of the S8 stuff from it, it's still 361mb. I'll see if I can delete out anything else.
*edit*
Does this Mega link work? https://mega.nz/#!43wERRoQ!0d2AbZzuNtkIJE9k96mq-VAGXc-F_SOa3fX7xQjQQJ0
also - I only put the Note 8 XAA and TMB omc folders in there, so if you pick any other CSC options instead of those I don't think it will even run.

Glad it worked for you. I would love to help the creator of that utility properly add support for our devices so that we have all the menu options, icons, etc.

well I read over that thread again and it said to get Wifi Calling working on Tmobile to first flash the ZTO CSC first, reboot and let the phone finish booting, then go back to TWRP and flash the Tmobile CSC and you should be able to enable wifi calling with a shorcuts app to launch a Wifi Calling Activity action but I still don't think it's working. Also I am looking at the ZTO CSC stuff and not seeing why adding it first would make any difference.
