[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

I really need help understanding CSCs...

Ok so I understand the basic concept of CSC codes, but their purpose is lost to me.
I bought a Note 8 Duos and it arrived with CHO/CHO/XSG. I live in Canada and I know that I can't get a Canadian CSC since the Duos is not sold here (unless there would be a way to get a 9500, flash a W8 ROM and keep dual sim somehow...?), but I'm also concerned about having CHO (Chile I think) while using the phone here, with things such as updates and all. I tried to flash BTU (UK) but it didn't work - just reverted to CHO.
So, to help me understand, could someone explain the following to me:
1. Does it matter at all which CSC code is on my phone?
2. Could I change the CSC at all and would I benefit from it at all?
3. Am I losing any functionality by having a foreign CSC?
4. Can I force updates on my phone?
5. Is there anything else I should know about playing with CSC?
The one thing I don't get is I cannot, for the life of me, get access to Samsung Pay even if it is available in Canada... I'm assuming it has to do with the CSC but I'm not even sure.
I know this is utmost noobishness, but I really need to get my head around all this, so any info, links, etc would be great.
Thanks
PS: I did do some extensive searching so please don't remind me of the existence of Google... I checked

Flashing SM-N960W Canadian firmware on a SM-N960FD UAE phone for samsung pay?

Hi,
I recently bought a Note 9 (SM-N960FD) from Duabi and went back to Canada. Now Samsung Pay is not working here at all. It gives me an error message that it is unable to connect to server.
I have been looking for solutions around for the past 2 days with no luck.
What I reached is that I have to change the CSC of my phone (which seems to be a much more complicated process than just flashing a firmware with ODIN). And some suggested that this will be of no use as my phone is exynos and Samsung Pass will not work in Canada unless it is a Snapdragon phone!!
Also the model is different here in Canada. It is SM-960W (with XAC as the unlocked version).
What do I do? I want samsung pay to work on my phone. Shall I change the CSC and flash the Canadian firmware? Is it Okay to do that with the Canadian firmware designed for a different model (960W and not the 960FD)
Please advice.
Thanks

sammobile firmware to change csc
hello,
I was in a similar case when i bought my note 9. It was from Taiwan and I am from Spain.
I flashed the spain firmware from sammobile
https://www.sammobile.com/firmwares/recent/
and now my Samsung pay and other apps work natively. I was told by Samsung Taiwan that flashing other csc can cause incompatibility, so take that in mind because although it may not seem real, the different versions of smartphones have different hardware.
Research a little bit from the forums.
I had the sm-n960f/ds and i installed the software from the sm-n960f from Spain.
Also, install cpu-z so that you know well what chip is installed inside and more info that could help you to fix this issue.
This is only informative, I don't take any responsibility of any damage.

unfortunately you cannot flash different model firmware on different chip.
so ure stuck. the only way id see ure spay working again might be using a vpn and choosing one of the region phone is from. but id doubt this would be a good long term solution. but as a proof of concept, it might be nice to try.

Changing CSC to enable VoLTE and VoWIFI

Hi there,
I'm about to order a Galaxy S10 directly from Samsung since they are way cheaper than what my carrier sell them. But, when I do my carrier tells me that VoLTE and VoWIFI will not work on Android phone bought from other than the one they sell...
I've read a little bit and it seems that I'd have to change the CSC of the phone, I've chatted with samkey about the particular model and it's not supported, because of bit 4 or something like that. Anyways, I've downloaded samfirm and found the firmware for my provider "VTR" but it seems that all firmwares from any provider in Canada share the same thing because what is getting downloaded is a "VLS" and the CSC one is "OYV"

I need advise to modify the firmware or options in my new phone to make it look like it's coming from my provider (Videotron) and when I insert the SIM (with NFC+VoLTE) in it I have a chance that the option will be available.
I'm an IT Specialist, I've flashed my old S7 with those files before with no luck. It's the same story with the S7, bought from Samsung, initialized with an other provider SIM though. Then flashed the phone with my provider CSC got a proper SIM card and I had them enable VoLTE on my line, but the option never showed up. I'd like to be able to enable it on my new phone, that's why I'm doing research before getting my hands on it.

Can't you just download the video tron firmware and flash it to the phone with Odin?

I sure can, just wondering if it's gonna work since last time I did that on my S7 it didn't work.
I downloaded the firmware using SamFirm v0.5.0 for 2 providers, VTR (Videotron) and RWC (Rogers) two very different providers and I compared the two CSC files using sha256 and they are both identical (I didn't test the big 5G files though, but they have the same exact file size). So I'm wondering if I'm even downloading the right thing now. It's probably multi CSC. Then does the stock Canadian Samsung firmware the same as the one I'm downloading?

It should tell you on sam firm what firmware you need to download or if you're running the current stock firmware, then just look in settings to see what base band you're on and go from there. I wouldn't flash rogers if you have another carrier, that may cause some issues.

Thanks I'll look into it a little more when I actually receive the new phone from Samsung. I wasn't going to flash a Rogers firmware, I downloaded it to do a compare and check to see if they actually are identical to VTR ones and they seem to be identical, at least the CSC files are.

many folks have found that buying direct from samsung doesn't guarantee the phone will work.
several on xfinity mobile found out the hard way.

Question Change CSC S21 ultra

Hello any solution to change csc on s21 ultra? Samkey not work

it seems there is no way curently

I did this method and it worked https://androidmore.com/change-csc-samsung/
I have a s21 ultra exynos , and a unlock phone , global version
I installed the AUT update via odin and the csc was TPA , so i did the method on the link to change to AUT and it worked but it deleted everything

but what about Carrier blotware?

Which step on the link did you exactly do? There are many options.

Any update on this? I have S21 Ultra with TPA and I want to change the CSC to BTU. I am in Canada and I hope this will help with faster updates. Also I am having problems with slow 4G uploads, and faster updates might be the solution.
Thank you..

If your device is SD then you won't be able to get BTU.
If it is exynos then you can flash the BTU firmware.
Your 4g speeds may be slow if you do not have the correct csc files for your provider. Eg: having BTU for Rogers may not get your the speeds you are looking for.

I used the link in this tread and I selected BTU, but I did not pay attention that it was mentioned that is Single. Now I have BTU, but I have some problems receiving SMS and I cannot go back to TPA. When I try *#272* IMEI# it does not do anything. Any idea what I have to do to go back to Dual SIM?

You will not be able flash Canadian CSC on an exynos device.
First you have to root the device and Either you or some else will have to edit the canadian csc file to make it compatible wtih exynos.
Some one has done for me in the past with note 8 but that dev is no longer in XDA.
The other option is to root and then copy the required csc files.
With this there is a high chance that the imeir related files can get corrupted.

You can flash any other file with multicsc.
There is no reason for you not recieve sms with BTU csc. However, if it does happen fhe csc firmware that is the original one. i.e look at the third tri letter in the csc info.(this third letter never changes , more like hard coded)

I do get SMSs but, I was not able to get one from my bank. The 3rd 3 letters are still TPA. I do not know if it is normal, but the dual sim menu has much fewer options. I can choose from what sim to call only after I dial at least one digit. And When I try to activate Dual sim always on, the toggle still stays off.
For the Canadian CSC, I suspected that it will be impossible to flash. I used to be on TPA and now I am on BTU, I had problems slow upload speed on 4G. Now is a bit better, but the download is staying around 50-75. before I had 160-300 Mbps.
Where I can get Multicsc and do I have to root the phone?
Thank you.

Rooting won't help you much with signal or speed of data, unless you have to flash some modified csc files.
Your problem could also be the absence of the required bands,whuch may be lacking in exynos.
I have a SD version ( decided to go wtih non root this time as most of the things that need root can be done with adb anyways. Also there is root for SD too these days) so cannot help you much.

Chainging csc is easy by flashing the CSC file. Rooting won't affect it. Rooting has its downsides.
Your loss of dual sim fn could be related to csc but BTU should support full dual sim fn.
