How to change CSC on Samsung Galaxy S3?

Samsung Galaxy S III firmware has 3 main components ~ PDA, PHONE and CSC. PDA == build version of the firmware, PHONE == baseband / modem version and CSC == consumer software customization (specified to geographical region and carriers). CSC contains the software packages specific to that region, carrier branding and also APN settings for data connection, MMS for your service provider. You can change CSC if you have Multi CSC packages like below example. By the way, only Samsung Galaxy S3 firmware with correct PDA, PHONE and CSC combo will get updated with Samsung Kies.

Note – This will factory reset your phone. Everything will be deleted. Do backup before perform this task.

  1. meaning some guys didn’t get the update due to wrong CSC??

    AP : I9300XXBLH1

    CP : I9300DXLH1

    CSC : I93000LBBLH1

    is it the latest 1? i heard got another small update for modem.

  2. I purchased my phone samsung s3 in New zealand where it had been imported from france, I didn’t have any issues with it there, but I recently moved to Denmark, and I am having major connectivity issues with the carriers over here, could changing my CSC help fix this? cheers

  3. Juz get back my s3 after front camera from Samsung Service centre. Check with kies, I am no longer supported to update via kies, can you suggest which csc code should I select in order to get the update via kies again?

  4. My Galaxy S3 international unlocked factory has BTU code, I want to upgrade to the official I9300XXDLIB Jelly Bean firmware with Odin. My question is: If is neccesary to change the Csc to the XEO code for apply to the JBean firmware?. And my concern is: the Samsung Kies will recognize my model phone after applied the Jelly Bean update with the modified Csc or not?. Thanks

  5. Hi.. i purchased s3 in china.. its already rooted and i want to change the csc.. but only TLS is the option i am getting.. how to change to poland csc to upgrade to jellybean..

    • Hi Sunny, I am not sure that China I9300 hardware is the same as international I9300 or not. If it is the same, you can install other region firmware directly with Odin. It will change CSC automatically based on the firmware that you installed.

  6. Thanks sir for your quick response.. how to check if its same or no. ? I just want to make sure i not end up messing everything..

    Does this signifies anything.?

  7. guys, I’m really confused, I just moved from the world of iOS to Android, I have Galaxy S3 with CSC code THR, I live in Libya.

    Kies doesn’t show the new JB fw yet, so does it going to change it if I change my CSC via *#272*IMEI# or it is useless? if I could, then which CSC code should I change to?

    my *#1234# info is:

    AP: I9300XXBLFB
    CP: I9300XXLFB
    CSC: I9300OJVBLF3

    I tried Check Fux Downloader 2.1, but it didn’t show up my firmware info.

    this made me so confused.

    when I try to change my CSC I get the following codes:

    so what should I do?

    thank you for your support to a new comer!

    the KIES software is causing me some trouble, i cant backup my phone. any ideas?

  25. Dear Jayce

    This may come as often repeated, boring (and possibly stupid) question to you, apologies if it does.

    My SIII bought in Australia from Hongkong based firm has following information displayed:

    Model no: GT I9300
    Android Version 4.0.4
    Baseband version: I9300XXLH1
    Build number: IMM76D.I9300XXBLH3
    Kernel version:3.0.15-928452 se.infra@SEP – 70#1
    SMP PREEMPT Tue Aug 21 17:04:13 KST 2012

    I was hoping it would come with Jellybean (as on my Nexus 7 tablet)

    Does everything appear okay and should I just wait for update – or am I missing something?

    I will be grateful for your expert opinion.


  26. hi jayce, how can i tell if my CSC code match my firmware? mine is:
    AP: I9300XXBLFB
    CP: I9300XXLFB
    CSC: I9300OJVBLF3
    CSC of AFR

    Thanks in advance! x

  27. Hi dear, i own i9300 s3 an international model with THR (i.e from Tehran Iran), i live in Pakistan and jelly bean is available for Pakistan. My question is that if i change CSC to Pakistan will i be able to get jelly bean? since jellybean status is pending for Iran.

  28. Hi !
    I need help please, i just bought a brand new samsung s3 and i am running ICS 4.0.4 when i go to setting and try to update its says no update available i went to KIES directly and it says That Kies does not support the firmware…….
    I tried updating without wifi using my networks (Three) and nothing.
    I checked versions and it was
    AP: I9300XXBLFB
    CP: I9300XXLFB
    CSN: I9300OJVBLF3
    I want to update to the new jelly bean I live in UK can i do something about this please.

  29. hi i own galaxy s3 titanium grey version i wanna know which region it belong to my code is AP = i9300XXBLH1 , CP = i9300XXLH1 , CSC = i9300OJVBLH1

    i live in pakistan and wanted to update to jelly bean wot can i do ?

  30. Hello Mr. Jayce, I need help please. I have a 32Gb Galaxy S3 with Original ICS firmware which has upgraded Automatically to Jelly Bean 4.1.1 and this is the latest version of android.
    Now its current firmware version:
    PDA: JRO03C.I9300XXDLJ4
    CSC: I9300XXDLJ2 (EUR – England)
    It supported Farsi language and I can read Farsi Messages and see Persian Sites; but unfortunately it has not Farsi selection in System Language and in Samsung Keyboard Input Language. I like have an Original Samsung keyboard supported with Farsi language in addition to English in my device. And I don’t like install and use another keyboard application (for example: Go Keyboard) in my device.
    Therefore I want to change only its CSC with Official IRAN CSC (I9300OJVALE9) by flashing the file (CSC_I9300OJVALE9.7z) by Odin Suftware. But just now I want to know if I change my device Original CSC by this way, would I receive its firmware New Next Updates or Upgrades? Or this file changing would make update problem for my device?
    Best Regards
    Yours Sincerely – Dr. Ghandriz from IRAN

    • Hi Dr. Ghandriz, changing CSC does not give you new keyboard. You need to change whole firmware. And by changing CSC this way, you won’t get official update anymore since it does not match to your firmware.

  31. OK, Thank You. Already I have got matched firmware with IRAN CSC (I9300OJVALE9), but it’s version is ICS 4.0.4.
    Can I downgrade my device firmware from 4.1.1 to 4.0.4? Is this idea right? Or you don’t recommend this way? Really what is your best recommendation?

  32. hi im from singapore. i upgraded my gt n7000 firmware last month via kies. im just curious, why does my kies now says that my firmware is not supported for upgrading via kies?

  33. Hi, I have a S3 with XEH (Hungary) i9300XXBLH1 factory loaded firmware (all untouched) on it, but the JB update is taking forever for this region, How can I get the update now? Do I need to flash another country firmware and change the CSC?

    If this phone has multiple CSC available on the phone, can I just change the CSC to a country that has the update such as BTU or others?
    thank you!

  34. Hi,

    I have a galaxy s3 that was purchased in France. Can I flash it with a firmware of Netherlands?
    I live in Netherlands. What do I have to do? I currently have JB installed.

  35. Hi,
    I am from Kuwait and i have upgraded my GS3 to OFFICIAL JB Poland version through ODIN, now kies doesnt allow me to chk for update it shows

    Yours Device’s Current Firmware Version is Not Supported to update Firmware via Kies

  36. Hi Jayce,

    Im in India at the moment and picked up an S3 here. I’m running 4.0.4 and would like to upgrade to the 4.1. I’m having trouble connecting Kies and when I try an ota update, It says there aren’t any available.
    When I bring up my csc options, India isn’t listed either.
    Would it help flashing the phone with the Indian 4.1 Firmware using odin ?
    Would I have compatibility issues with my csc or would the new firmware over ride it ?

    Thanks in advance.

      • Jayce,

        An update on my issue. I downloaded the India baseband 4.1 version and flashed it sing Odin.

        It worked just fine. Now i’m registered officially on the Samsung India servers. Got 4.1 Running. Kies works just great. And I didn’t even lose any of my saved data. CSC now says India too.

        Hope this helps anyone looking to do the same. Cheers.

  37. hi jayce,

    so i got this sgs3 int’l version gt-i9300 and i flashed it with the ultima rom v5.0.2. how do i go back to stock firmware to get the the premium suite upgrade which has been released recently? thank you very much.

    also, congrats on the awesome site!


  38. Hi,

    I just bought a new galaxy s3 in China which is from China Unicom (Chinese telephone service, I just found out later) and everything is chinese application and there is no play store(I tried installing playstore but once I launch it then it blacks out). So since I will not be using my phone in China can I change the firmware or something? Because Chinese version of 4.1.1 doesn’t allow me to change the CSC. The phone is international version.
    (GTI9300) My Version is:
    AP: I9300ZNDLK4
    CSC: I9300CHUDLK4
    The news I read on the internet is that China Unicom blocks Google and google also blocks china Unicom so I just want to use Play store in other countries not in China. Is there anyway?

    • Hi Osric, I am not sure China SGS3 is using the same hardware as international SGS3 or not. If yes, you can install other region firmware. If no, you can’t do so. Try to consult others at XDA Forum see.

      • Hi Jayce,

        Thank you for your proficient reply I really appreciate it. However I coincidentally found a friend who was using android galaxy note phone for a while so he offered to help root my phone so ones rooted it it was actually really good and able to use playstore without anymore china’s unicom influence. But before that I went to my country Thailand and tried asking their help we went to many stores and many places and waited quite a while no one seems to be able to address the problem until now. I was lucky to find this friend who was super willing to help. But again I really appreciate your reply. If I have any other problems with the china unicom or other android phone I will definitely ask you. BTW I wanted to ask you what are you thoughts on galaxy 4? Since it has many cool features but I heard from friends that it has a problem that it heats up quite fast and many people returned it to the store I do not know whether its true or not but I was actually wanted to buy galaxy 4 but I am hesitating so I would like to know your thoughts and if not galaxy 4 then what android phone would you suggest?

        Thanks again for your help


    • i have the solution for you problem, if you still have it, please contact me. i can help you.
      i have a sgs3 china unicom, and i flash it with china modem, and nordic countrys rom.
      it works so good, i am in mexico, and i use it without trouble.

      • Hi Carlos

        Thank you for your help my problem was already address but if I ever found any other problems regarding to the changing the country of the phone I will definitely ask you about it. I am considering buying a galaxy 4 but my friends said it get hot very easy so they return it to the store since I am in need of buying a new phone soon I don’t know which android phone to buy since iphone likes to move on with their products I don’t want to kept one changing the phone to follow them so do you have any suggestions?

        Thank you again


  39. hi there , i bought an international version of s3 from palestine where i updated it for the first time with no problems , now i moved to egypt and the jellybean update had been here for a month but i didn’t get it and im not receiving any updates even minor ones , i cant even connect to kies where it says :” your phone does not support software updating via kies” and ota naturaly shows no update available
    the question is why cant i update , is it because for some reason my phone is still connected to my carrier in palestine and i only recieve updates when they begin rolling there ?

    and if i used factory reset would my phone begin getting updates and act as a phone in the Egyptian market ?

    i’m so frustrated by this problem i cant believe no one have an idea how to solve this ,
    please help πŸ™

  40. hi!
    u also use JB right?
    i wanna ask, u say that change csc won’t help to get the latest update from other region right?
    so, if i get from sammobile the leaked or not firmware, example from germany, do i need to change the csc of that firmware to match with my country csc code?
    do you have a list of csc code?
    if i don’t change i’ll get the mess on my sim card, affect the signal performance, and etc??.

    or it just need to be changed on custom rom or firmware?

    • and ex :
      I9300XXELL5 Download (Thanks To SamMobile!)
      Base Firmware: I9300XXELL5 (4.1.2)
      Region: Europe
      Country: Germany
      Carrier: Vodafone
      Build Date: 10 December 2012
      Modem: BUELK1
      CSC: VFGELL1
      Change List: 672976

      above is latest,
      my country is indonesian, so i must changed the csc code to indonesia csc code?
      will it make better the signal?
      will it be a problem if the carrier : vodafone used on sgs3 international GT-i9300?

      • sorry, to confuse you, but ‘ll re-ask since i also confused by the answer..
        based from above example of fw,

        first even the csc is difference (stock or custom), i don’t need to change my csc code, since it’s difference? and not changed, also won’t affect signal or other problems.

        and i have search a little about branded and unbranded difference.
        so above is branded, if mine is international version, i can’t used that firmware? since it’s branded for specific provider or server related to SIM card?

        if it’s unbranded, i can flash it to my phone? (though it’s mean free to use any sim card?

  41. no mean not need?
    what i mean is i using the international original from samsung, but i wanna install unbranded firmware?. wait unlock mean international?
    so tat unbranded fw, mean i can use any sim card right?

    Flashe, via odin, a stock rom (BTU) version of 4.1.1 at christmas.But since then my CSC has been KOR though and thus Kies not working.

    Flashed today to 4.1.2 of stock TMU but still CSC is KOR. I am not rooted (and a noob) and just want kies to now recognise my phone

    any help???

      • Nope. Goes to dial and comes up with “Connection problem or invalid MMI code.

        Apparently since I updated last night I dont have any mobile data either now? Maybe that has something to do with it? Still have phone signal but no data

        • the net work issue is no longer a problem, factory rest and its back, but still getting the β€œConnection problem or invalid MMI code”

          Tried a CSC changer off Play Store and it comes up with, “PreconfigUI does not support SIngle CSC”

          • ok. apparently after all this, ive plugged it into Kies this morning (UK), must have done it 6 or 7 times last night, and it apparently is now TMU and works.

            Thank you very much for the help!

  50. I broke my phone and got a replacement handset sent under Orange Care, The phone has absolutely no bloatware but it’s still locked to orange, Another thing my phone has is the option for OTA updates, whereas most orange phones have had that removed from their options. When i click it it instantly comes up with “No Update available”, The ridiculously annoy part is when I plug my S3 into Kies, when it doesn’t come up with the furiously irritating “HardwareID Missing”, It comes up with “This device is not compatible with updating via kies!

  67. hello there. I’m justwacky and i’m curious about how this csc thing works. I know a bit of information thanks to your introduction above. My problem right now is:

    -I want to change the csc code for a Lenovo phone (bought from china). The model is A280. The problem is, I can’t find the malaysian firmware for this. Can you please advice me on what to do? Many thanks.

  68. Hi Jayce I am not new to flashing or any of that stuff, but I do have a question: My phone’s csc is TTT(Trinidad and Tobago ) and I think they lag about 1 month behind of BTU(UK or EURO) firmware on updates. I do have everything I need in the original firmware(TTT), but would you recommed flashing the phone to lets say UK(BTU)? One thing I want to point out is in 4.1.2 Samsung removed few input languages, just don’t know why. I even emailed Samsung and the reply was that indeed some languages were removed. Thanks

      • I don’t really need it, the only thing is that UK’s variant seems to have more updates of some sort. When I check sammobile website I see that UK version had few 4.1.2 updates. May be these are only minor bug fixes….Thanks

  72. If I flash my s3 to a different region, using an official rom, would it update with kies later? And what is the csc for Saudi Arabia? I found two: JED and KSA, whats the difference between the two, which one should I choose?
