I never used U/U1 phone, all currrect are Europe's B or F models. Even stop rooting them, my last rooted was Samsung Note 5. Thats why I wrote at the end of my previous post: "if there is a way current firmware to be rooted".
[Samsung Galaxy S22 Ultra] dj24:
There is currently no available method to root U/ U1 devices.

Hi ChoSmile,

I'm on Galaxy A54 (A546B) - OXM / EUX version, aiming for the ODM / INS (A546E) version.

1. Can I simply flash the BL AP CP HOME_CSC of the latest A546E version with Patched ODIN?

2. Do I need to backup / Will data be wiped?

3. Do I need unlocked bootloader for this?

4. Will banking apps still work & KNOX remain untouched?

Many thanks!
[Samsung Galaxy S22 Ultra] garfi:
I have TUR (Turkey) CSC,

changed CSC to ILO, INS, THL and SEK

I tried of all them, when dialing someone, his/her numbers does not have space between digits,

example: 0212 5XX XX XX but in all CSC, it shows 02125XXXXXXX

do you know any CSC which has space between dialer digits and also call recording option?
[Samsung Galaxy S22 Ultra] ChoSmile:
No way to flash E fw on B device.
[Samsung Galaxy S22 Ultra] ChoSmile:
No way. Choose callrec or spaces.
[Samsung Galaxy S22 Ultra] RKSTN:
I changed my device CSC from EUX to INS. So, it's still possible to change the CSC on the S23.

I followed this tutorial:

How to Change CSC on Samsung Devices without Root

Here is how to change the CSC of your Samsung Galaxy phone for free without resetting your device and root privilege.

Hello ChoSmile,

I'm from India on Galaxy S23 Ultra SM-S918U1 (12GB/512GB) handset bought in USA.

I use Vodafone(physical SIM) and Jio(eSIM) as my service providers. I don't have 5G services or call recorder facility active on my handset. following are my queries:-

1. How do i change my CSC code XXA to INS without rooting my phone.

2. Do I need to backup / Will data be wiped?

3. Will i receive all the OTA updates whenever they are released for the Indian region? per Indian releases.

Sorry for being ignorant and thanks in advance for all the help and guidance.
[Samsung Galaxy S22 Ultra] ChoSmile:
Sorry, No way for U, U1, W models.

They do not have CSCs with Call Recording enabled feature. Can NOT use firmware from different model.

Better proposition:

Sell your U1 model and buy B model.
[Samsung Galaxy S22 Ultra] Sputnikmp:
Thank you ChoSmile for the prompt reply.

Just a concluding question.

Since it's not possible for me to sell the phone... let's say if I were ready to root my phone (or do anything that is required), is it possible to have native call recording and the 5G services activated.

Thank you.
[Samsung Galaxy S22 Ultra] ChoSmile:
Root is not possible at the moment. Or I do not a working method for The model.

Also after rooting Knox tripped, no warranty, can not be returned ever.

All security apps, bank apps, some games may stop work, like Google Pay. There are methods that may hides "root" but on every firmware update and Google Play Protect update this "hide" may become useless until next "hide update"... so, "cat and mause game".

In my opinion:

It is not good to root even you found way to root.

Hi

Hi my phone is a Samsung s21 fe 5g - SM-G990E_OJM_MID and I don't have a call recording how could I get a call recording?

Can I change the csc without having a problem with my mobile warranty or my mobile update?
[Samsung Galaxy S22 Ultra] ChoSmile:
Option 1

ILO CSC have Call Recording and CallerID features and it is part of same as current OJM MultiCSC (MID CSC), so only SamFw can be used for CSCs change.

Option 2

For others (INS, THL, XXV,...) first need ODIN (BL, AP, CP, HOME_CSC) flash and then SamFw change.

Neither option voids warranty or data loss and OTA updates will work.
[Samsung Galaxy S22 Ultra] boxorprime:
I am a beginner, please tell me a little more about what I should do

That means I can't directly convert CSC to SEK with SamFw to use the call recording feature?

When I bought it, it said Ukraine in the box, but this function is not active for me at all, I don't know why and I don't know what OJM MID means, does it mean to lie to me that this is for Ukraine?

How can I activate this call recording problem now?

Thanks
[Samsung Galaxy S22 Ultra] ChoSmile:
Your model is for Middle East region, MID means Iraq CSC, part of OJM region (MultiCSC).

In same region (MultiCSC) is ILO (Israel), you can change to ILO with SamFw

There are tons of guides how to use SamFw (including here in XDA, even in videos in Youtube).

SEK is CSC for different model SM-990B, your model is SM-990E and can NOT be changed to SEK
[Samsung Galaxy S22 Ultra] SgAndrea:
Hi! Is the same for s22 ultra? B version. Tnx
[Samsung Galaxy S22 Ultra] ChoSmile:
S22 series B model - only SEK,

other CSCs are in E model.
[Samsung Galaxy S22 Ultra] SgAndrea:
Work on s23 plus? Tnx
[Samsung Galaxy S22 Ultra] ChoSmile:
Yes on B models (SM-S916B).

No on U, U1, W
[Samsung Galaxy S22 Ultra] CluelessCorpDrone:
ChoSmile,

Since you seem to be very knowledgeable, would you mind answering a few questions for me?

I am trying get some phones for our staff to record calls with. We are based in the US and use Verizon as our carrier. Most threads indicate that a CSC change is best, but from what I'm reading in your posts is that the USA models I can acquire and use domestically do not allow this?

1. Will using Verizon and being in the USA pose any technical hurdles that would prevent a CSC change?

2. Is the S22 S901u compatible with this method? If not, what in the S22/S23 family do you recommend that I can buy in the US through Verizon? Or what is a suitable modern android alternative you'd suggest?

3. Will we lose OTA? If so, do I have to change the CSCs every month and change them back?

3b. If I need to change CSCs to get an update, will the previously recorded calls get lost when the record option is hidden? Will I have to back the recordings up beforehand?

4. Orders from on top are no rooting or warranty voiding measures if possible, and I am technologically clueless enough that I just don't know what the best option here is.

5. What about apps like ACR w/ the helper phone app, CubeACR, or Skvalex? Are those good options? Clarity of the recording is a high priority, if possible.

Thank you for you time; I appreciate it.
[Samsung Galaxy S22 Ultra] ChoSmile:
CSC change is possible. Just any of the model SM-S91*B (Europe, Asia, Middle east, Australia), SM-S91*U and SM-S91*U1 (USA), SM-S91*W (Canada), SM-S91*0 (China, Hong Kong, Taiwan), SM-S91*N (South Korea) have different CSCs for the region.

For U model available CSCs are: ATT,CCT,CHA,DSA,DSG,DSH,TMB,TMK,USC,VZW

For U1 model available CSCs are: ACG,AIO,ATC,ATT,CCT,CHA,DSA,DSH,FKR,LRA,PCT,TFN,TMB,TMK,USC,VZW,XAA,XAG,XAR,LLA

CSC change can switch ONLY BETWEEN model's CSC.

Can notchange to EUX or SEK ot THL or any other CSC available for B model.

Can NOT change MODEL U to B.

NONE of these U or U1 model's CSC have Call Recording feature.

European users can use their B models (with their SIM cards) in USA. If there is an restriction(s)/allowance to use Verizon SIM in B model - as your operator (Virison).

No. Device will continue have OTA updates then new active CSC update is pushed. But this is again only between (1.) CSCs.

No. Recording are not lost/hidden/deleted when CSC changed. But (1.)

If rooted the recording call can be enabled on any CSC. But waranty void. I'm not sure if there is an working root metodfor U/U1 models.

Recording with extarnal app do not have access to audio stream (after andorid 9), so both sides (your voice and your interlocutor voice) are recorded by you phone's microphone - this requires volume of the interlocutor to be enough high (up) to be captured by your phone's microphone and recorded with less lower volume (compared to your voice), ambient sounds (around you) also recorded.

Just try them and deside by yourself.

Hi, i have BTB, BTE, EVR, MEO, MET, SFR, TSI, BOG, CAU, CPW, EUX, EUY, MOB, MOT, MSR, O2C, PLS, PRT, SEK, SER, SIM, SKZ, SWC, TIM, TOP, VIP, WWA, WWC, WWD. My first csc is EUX i live in Poland. I no need to record call, I only want to call ID and samsung pay. What csc I need to choose?
[Samsung Galaxy S22 Ultra] ChoSmile:
Maybe some UKs (first three) for SPay.

Not sure for Callid.

Only SEK have Call Recording.

Try all via SamFw app (skip WWx) they are demo/test and share results with us for SPay and callid availability. (no data loss, free)

Also share exact model SM-XnnnY!
[Samsung Galaxy S22 Ultra] PriNz@xda:
If i change my CSC Code to enable Call Recoring Feature and i decided to do Hard Reset/Factory Reset, will i do this method again?
[Samsung Galaxy S22 Ultra] ChoSmile:
Yes, unlimited times... unless if Samsung deside I some feature firmware to block CSC switching.
[Samsung Galaxy S22 Ultra] JackFrost6:
I have phone Samsung a34 5G EU.

Test CSC and get info, avaiable CSC is

BTB, BTE, EVR, MEO, SFR, BOG, CPW, EUX, EUY, MET, MOB, MOT, MSR,

O2C, PLS, PRT, SIM, SWC, TIM, TOP, VIP, WWA, WWC, WWD.

I need call recording.

my phone won't let me use anything else. Can you advise me, is one of the selections for recording a call?

or should I not try at all, I have no chance? I want no root.
[Samsung Galaxy S22 Ultra] JackFrost6:
Native Call Recording EU version Motorola One Vision.

Can I easily change to Motorola without root? I have an older phone, I use a third party app, but the record is not good. But I couldn't find out if it has any CSC using SamFW Tool, it can't be read.

is it possible or there is no such chance with a phone like Motorola?
[Samsung Galaxy S22 Ultra] ChoSmile:
No, it is for Samsung only - gives command to switch between existing (inside their firmware) CSCs (Country Specific Code). Different manufacturers have completely different firmware organisation.
[Samsung Galaxy S22 Ultra] ilpincio85:
Has anyone tested whether this method also works with Android 14 One UI 6 stable?

edit:

tried myself. works like a charm
[Samsung Galaxy S22 Ultra] DaOldMan:
Factory reset doesn't change csc unless they changed something lately, it should stay the same as before the reset.
[Samsung Galaxy S22 Ultra] arpcpro:
I cannot change the CSC of XCover6 Pro/SM-G736B to INS. It is not on the list. If I flash the THL firmware, will then allow me to change to INS or INU.
[Samsung Galaxy S22 Ultra] ChoSmile:
This model SM-G736B was not available in India, so there is no INS/INU.

I suppose your current CSC is EUX, so it is part of OXM MultiCSC.

THL is part of OLM MiltCSC, so first you need download full THL firmware and flash with ODIN (BL, AP, CP & HOME_CSC). Then change to THL via SamFw.
[Samsung Galaxy S22 Ultra] arpcpro:
@ChoSmile, correct my firmware is OXM_EUX. SamFW allows me to change to CAU, CPW, EUX, EUY, MSR, SKZ, TOP, TUR. Perfect would be INS, because it has everything.

The THL does not have Samsung Pay according to you ("THL - call rec, call ID/spam, no SPay"). On other pages they claim to have Spay on THL, but I've flashed with THL/XSA firmware and when I launch Samsung Wallet it tells me that my phone is from a country where Wallet is not supported.

XXV Vietnam does not seem to be available for my SM-G736B.

I would prefer to keep SPay and just add call recording at least. Because for the caller id/spam I've read that we could install the Hiya app.

Is there any complete list with all the CSC ids and the features they enable?

So far I've compiled this:

Spoiler content hidden.

Edit: It is strange that Thailand's firmware does not allow Wallet to run because it was launched there: https://news.samsung.com/global/samsung-pay-launches-in-thailand

Edit 2: I saw now that SPay was discontinued on Dec 2021 in Thailand :( This explains why the CSC features do not match for THL. The ones claiming SPay on THL are not up to date.

Guys if i change via samfw from xsg to ins csc will i get ota updates normaly? My model is 908e/ds

Hi, I am in the same situation, I have a S22 ultra Canadian model and I want to find a good solution to record calls 2 ways with clarity and also be able to record over Bluetooth headset.

while I was reading the thread I remark that there is no answer to your original question which is "Solution for Canadian/USA Models".

Anyway. I appreciate if you share with us the solution ( if you found one ).

thank you.
[Samsung Galaxy S22 Ultra] ChoSmile:
The only solution is ROOT, if you find a way to root it and all and all the unpleasant consequences of the roоted device such as manual update only, non-stop looking for way for hiding root to run secure apps, banks and some games because google also serching non-stop way to detect hiding, and if matters: warranty voided.

Other option: get international model B or E.
[Samsung Galaxy S22 Ultra] Lyris113:
Thank for the quick answer.

That really so sad to have such expansive phone and you could not use a basic functionality like call recording.
[Samsung Galaxy S22 Ultra] ChoSmile:
The functionality (basic or not) is forbidden by law in certain countries, so Samsung follows the law and hides this functionality.

Google also follows the laws and forbid access to audio stream in Anadroid 9, leter forbid access to caller id during incoming call.

iOS never had such functionallity.

A workaround also could be using external Bluetooth handsfee with internal recorder, there noone can stop you to record audio stram

bluetooth handsfree with recorder - Google Search
[Samsung Galaxy S22 Ultra] Philip:
But there is nothing in UK law (where I live) to prevent me from recording conversations, so there is no legal reason for Samsung to remove this functionality here.
[Samsung Galaxy S22 Ultra] ChoSmile:
GDPR.

If you are not agree - go argue with Samsung :)

I'm in same "boat" and at the moment use different CSC in my Samsung phones.

Off topic:

Generally, as I know, not sure, officially if in the conversation has 3rd side (person or recording), it have to be announced in the beginig and beeped at least on every minute.
[Samsung Galaxy S22 Ultra] Philip:
I n the UK there is no legislative restriction - GDPR or otherwise - on individuals recording telephone calls, and there is no requirement to inform or to receive the consent of the other party to that conversation.

(The law applying to companies is different, and of course there are restrictions on what you can do with the recording, but there is absolutely no justification for Samsung to remove this functionality on the grounds that it might be used illegally. That would be analogous to a kitchen shop refusing to sell me a knife just in case I chose to stab somebody with it, or a garage refusing to sell me a car just in case I might break the speed limit in it, or...)
[Samsung Galaxy S22 Ultra] ChoSmile:
So, are you ready to file a discrimination lawsuit!? 🤞
[Samsung Galaxy S22 Ultra] Philip:
Not sure that it would meet any of the "discrimination" criteria.

At the end of the day, Samsung are selling a telephone which does not have the ability to record calls. It's entirely up to me, as a consumer, whether or not I buy that product. I can choose not to buy a Samsung handset; I can also choose to buy a handset from a different manufacturer. Either way, mush as I dislike the situation, I'm not being discriminated against.
[Samsung Galaxy S22 Ultra] ChoSmile:
Just out of curiosity is there any brand that officially offers call recording as a core functionality in their devices?
[Samsung Galaxy S22 Ultra] billa:
You could try a third party call recording app, some work better than others depending on the make, model, and firmware version of your phone.

If that doesn't work, you could try a regular voice recording app. Just tap on the speaker-phone during a call, activate the voice recording app in the background which should record both sides of the call (adjusting the volume may be required). While quality may not be the best, at least it should work on any phone. ;)

By the way, while changing CSC on some models enables call recording, it may also affect other functions negatively like disabling other functions and/or limiting certain bands by the CSC's country of origin.... something to keep in mind.
[Samsung Galaxy S22 Ultra] DaOldMan:
Some Chinese mobile maybe. They have other problems with international roms. OnePlus installed now Google dialer that prevents recording in most countries because stupid Google just don't care. They enable recording in two countries and others they send to hell. You can't enable recording unless rooting. At least on OnePlus it's easy to root and unroot, unlike Samsung that disables Knox on first root and it can never be enabled again.

But we on XDA can learn to change csc and enable recording. You need international version for that. USA and Canada don't have this functionality at all. So Samsung for me always records just fine.
[Samsung Galaxy S22 Ultra] ChoSmile:
Yes, I knew the most of them. For me call recorfing is also one of the moest needed and used function when I choose my next phone, my latest ten+ are Samsung brand. A lot of comments/answers for CSC change threads are mine.

The question for "curiosity for others brands" was for Philip and what can or cann't do to make some brand to include or hide functionality. (Never mind.)

If Google don't care or follow/obey some rules/regualtions (or whatever someone call it) are tottaly different discusion which I don't want to be involved.

Nice hollydays to all :)

Hi. My Galaxy S10e (SM-G970U1) bought in the United States and has Android 12

I am currently in Israel and I'm having trouble recording phone calls (I use Cube ACR).

I tried to change CSC few times (with SamFw) to be enabled to do so.

Each time I tried a different code. They all worked but lasted about 24 hours and then it was back to normal, and calls cannot be recorded.

It should be noted that every time I check on the phone under the setting: "Service provider software version" - I get the same number/code and it does not seem to have changed to the new code.

Any Idea what do I need to do in order to be able to record phone calls?
[Samsung Galaxy S22 Ultra] billa:
Sometimes the carrier configuration folder gets corrupted, therefore I'd back everything up to an SDcard using the Samsung Smart Switch app, then do a full factory reset. Set up the phone as new, and try changing the CSC with your sim card inserted before restoring any of your data. Depending on your currently flashed firmware, it may or may not be possible to enable call recording with any of its CSC's. Usually the carrier free firmware "U1" is the best option. Let us know how it went.

Here's the link to the latest "U1" firmware if you'd like to try flashing it via Odin.

[Samsung Galaxy S22 Ultra] DaOldMan:
On new firmwares you can only use CSC that are in the firmware csc folder (some time ago it was possible to change to any csc and it worked). You can't really change it permanently to anything but a USA one (it will revert when rebooting). None of those allow recording. There is no free lunch (ie buying something cheaply on USA contract then using it abroad).

The only possibility to change this is by rooting probably. But that has other problems you need to be aware of.

When you change CSC for 24 hours can you record ? At least they didn't remove recording from the firmware all together....

Sorry mate
[Samsung Galaxy S22 Ultra] ChoSmile:
No option for US an Candada models (U/U1/W), except root but there have different troubles with security, bank, etc. apps :)
[Samsung Galaxy S22 Ultra] soundv:
Thank you for replying my post. after changing CSC code I can record with the "Cube Acr" app and hear the conversation. But it last only one or two days and than when listening to the recorded calls from the Cube app I hear nothing but silence. meaning that the app works and seems like "recording the call" but not really. I can't explain why after a day or two the phone can't record calls again
[Samsung Galaxy S22 Ultra] dr_adam:
I know the question is probably too early, but it is essential for my pre-order.

Does anyone know if it will be possible to change the CSC and activate call recording in the S24 ultra?
[Samsung Galaxy S22 Ultra] DaOldMan:
Probably, unless they have a "little" surprise in oneui 6.1 for us.... But remember you can only change to csc that is available in your rom.
[Samsung Galaxy S22 Ultra] ChoSmile:
Most probably YES for SM-S928B model which is available for pre-order in Europe, Asia, Middle-East, South America regions.

Unless Samsung desided to change csc changing methods or forbid it like N models.

US (U/U1 models ) and Canada (W models) most probably still will not have csc with enabled feature.

For 100% sure for B model, somebody have to receive their pre-order and test. Unless someone how have test device want to test earlier.

P.S. 20240122

There is firmware update for B model EUX ...AWM9 (xaxa... it means 2023, month 13)... inside available CSCs are also INS, THL, XXV, ILO... and etc. so waiting to see id CSC change procedure still works.
[Samsung Galaxy S22 Ultra] stakoz:
Zdrasti, yes I got my pre-order s24 ultra B/DS and the SAMfw tool for change of CSC works, from EUX to THL. Though want to try also another CSC as the G-Pay does not seem to work on THL
[Samsung Galaxy S22 Ultra] ChoSmile:
Did you test GPay on your S24U with THL or just read somewhere that "GPay seems not work in THL" on OTHER device(s)?

Problems with THL (or other CSC) on SOME DEVICE do NOT means that AFFECTS all or ANOTHER device's model(s) the THL CSC (or other CSC).

If GPay do not works (this means that on Google Play Store show Settings > About shows "Device is not cerified" and (for example tested with YASNAC) Google play Safetynet Attestation "CTS prifile match" is Fail) means that the problem EXIST BEFORE CSC CHANGE on EUX (or whatever CSC was before) or something else is installed, unlocked, modified, flashed or rooted ...

Just changing the CSC does NOT break Google Pay!
[Samsung Galaxy S22 Ultra] billa:
There's usually some trade-off when changing CSC's. While it can enable certain features, it may disable others, that's just how Samsung's silly region system works.
[Samsung Galaxy S22 Ultra] ChoSmile:
Google Pay is service that depends on Google's Safetynet and it not conneced by Samsung CSC regions.
[Samsung Galaxy S22 Ultra] billa:
Well, evidently it's not working when changed to your desired CSC manually. Whether it's not supported or some other glitch, the fact remains.
[Samsung Galaxy S22 Ultra] ChoSmile:
Who is the "eyewitness" who provides this evident?

Because the words of "stakoz" are " seem to" based on other devices, where there are different firmware files (more percisely bootloader) in the different CSCs and the problem was unceridied bootloader from Google.

Changing CSC by samfw do not affect Google Pay.
[Samsung Galaxy S22 Ultra] billa:
Gpay may be affected by CSC, not all regions are supported. If that's not the case then obviously changing it manually has screwed up something else in the file system. I would reflash it with full stock and try it again. If it's still happening with the same CSC, then draw your own conclusions.
