Yeah, I didn't need to, nevertheless, I remember reading somewhere that Samsung actually checks your SIM and changes stuff according to the country it picks from the SIM. I don't actually use Samsung Pay so I really don't know anything about it.

At some point I felt that the phone was draining too fast and factory reset it and everything works now.

You could use CSC and format it and see. If you have already flashed the other files doing a factory reset should do the same as flashing the CSC. I could be wrong though as I was away from Samsung for about 5 years and still catching up on things with flashing and whatnot for Samsung phones.
[Samsung Galaxy S21 Ultra] eyeatoma:
Okay cool, thanks for all the help man!
[Samsung Galaxy S21 Ultra] y2kkingboy:
I was wandering about the late updates and if I did something bad by switching CSCs or maybe just that they are late. Only time will tell.

Hi,

just to give a small contribution.

S21 Ultra UK, Firmware BTU on rev. AUB9

Just installed the AUB9 version of Indonesia firmware (XID). I flashed with Odin 3.14.4 ONLY the file HOME_CSC_...

All my data and apps are as before, no change to the settings, and no other changes.

The only app that does not work is Samsung Pay. Since Samsung removed the MTS capability I was going anyway to switch to google pay, so this is what I am going to do. Of course, If someone could suggest how to restore Samsung Pay it is appreciated.

The call recording is now embedded on the phone dialer. Great!

The nice things is that it works also with bluetooth earbuds, instead all other call recording apps tried before did not work on bluetooth.
[Samsung Galaxy S21 Ultra] zaffar.mughal:
I have the same question, although have the call recording but Samsung Pay is not working anymore. Please do let me know if you find any solution,, cheers,
[Samsung Galaxy S21 Ultra] mabmed:
What about esim? Still there.? Working or no? Thanks
[Samsung Galaxy S21 Ultra] mabmed:
Please, can you share file HOME_CSC from AUB9?

Thank you
[Samsung Galaxy S21 Ultra] GiomiUK:
I don't use esim but the option is still available. I use 2 sims (uk and italian) and they work fine.

The only issue is Samsung Pay but not sure if it is the firmware as the SP indonesian version is a different app drom the UK one and require a local wallet to add cards.

Hi all,

I have an international s21 ultra, on which I have flashed XID csc (only) over UAE firmware to enable call recording and it works fine.

Since Im able to purchase s21 ultra snapdragon version, I was wondering if its possible to flash CSC file from CHC ( China) firmware over BRI/TGY firmware to activate call recording? will this happen? only flashing csc from chc?

Really appreciate your help
[Samsung Galaxy S21 Ultra] Abu-khulzat:
Latest firmware AUB9, old CSC was XSG. after first time the CSC for some reason changed to EUX. Maybe because I was trying to change to INS. Then I turned on AIRPLANE mode and changed CSC again to INU and it worked. Everything works properly. Call recording is available and Samsung pay seems to be working. I registered my cards, but still didn't do any payments.
[Samsung Galaxy S21 Ultra] zaffar.mughal:
are you using UAE cards on Samsung Pay? or India?
[Samsung Galaxy S21 Ultra] Abu-khulzat:
UAE. By the way I have made a payment using SamsungPay, it does work flauslessly
[Samsung Galaxy S21 Ultra] zaffar.mughal:
glad to hear that, i have changed my CSC to INU (India) but Samsung Pay didn't work. Could you please guide me how did you manage to get it work?

I didn't do anything special, just set up sampay as usual

Got call recording via flashing HOME_CSC only from Indonesian rom.
[Samsung Galaxy S21 Ultra] Indi k:
Hi

I have S21 SM-G991B (UK /europe version )

I checked on Samkey and this version is not compatible ,but notice your 998B is not compatible and it still worked .

Do you or anyone here know if the Samkey will still work for G991B..

otherwise have to flash with Indonesan version ,but seems the Samkey maybe easier ..appreciate thoughts .

Only require the call recorder to work ...
[Samsung Galaxy S21 Ultra] Abu-khulzat:
Yes, it was also saying that my version was not compatible, however it did work to change the CSC. I think there is nothing to worry and you can safely try. Just make sure that your multiCSC rom includes the CSC that you want to switch to
[Samsung Galaxy S21 Ultra] Indi k:
Many Thanks for reply ! ...sorry never done this before .. but thinking use INU (same as yours) ..

can you possibly post link/instructions to get INU multicsc rom
[Samsung Galaxy S21 Ultra] Abu-khulzat:
I don't know about Europe, but in the Middle East we get OXM rooms, which include all CSCs of this region. Just Google it, you might have similar in Europe. INU, INS, THL, would work for you for call recording, if your room has these CSCs
[Samsung Galaxy S21 Ultra] Indi k:
Thanks again ..will have a look
[Samsung Galaxy S21 Ultra] Indi k:
Using Samkey ,getting error 'ADB device not found' any ideas as i can see connected in device manager ..Thanks all

I recently found a dailer replacement app that has call recording its True Phone. I have the Note20 Ultra on Android 11 and it works only downside is it doesn't work with bluetooth 😑. There's a thread on XDA for the app if you want to know more https://xdaforums.com/t/app-4-0-true-phone-best-dialer-contact-manager-replacement.2934816/
[Samsung Galaxy S21 Ultra] s3axel:
Over the recent days I tried numerous ways to get access to CSC features on a Bootloader locked/unrooted Device - so far without success.

One idea I'm following is that the CSC features lead to corresponding settings which may be modified by ADB. To follow along this route I need a bit of help from people out here with devices e.g. with Call recording enabled per CSC and/or other CSC features like live network speed...

Would any of you be willing to check whether there are settings in one of the settings locations visible via the Setedit-App (Link to Play Store) ? You would need to look for keywords as in the CSC settings in this list - e.g. " ConfigRecording" or " SupportRealTimeNetworkSpeed".... The only downside is it takes a bit of your time as the app sadly does not allow for searching :(

It would be very interesting if you could find a reference to the CSC-settings in your device settings....

Thanks for your help,

Axel
[Samsung Galaxy S21 Ultra] m046238:
Sir,

I was looking to activate native call recording on my S21U bought recently.

I was from Apple with a lot of burden concerning jailbeak to do that.

I root (or rooted, dont know) my new S21U easily. But not satisfied for call recording and the risk about securities concern.

I find your explanation with your solution.

That's perfect for me. Very thanks for the link in Mega (firmware). I will thank you too much for this sharing.

note : Here, i will protest against for this stupid restriction concerning call recording in many countries.

Stupid, Stupid, Stupid.

TBH ... Boldbeast and cube call recorder work quite well...but neither with Bluetooth.
[Samsung Galaxy S21 Ultra] ido100:
I'm considering buying the SM-G998U1, US Unlocked version

Anyone knows if it comes with call recording enabled?
[Samsung Galaxy S21 Ultra] shanda5303:
I used Boldest for years without issue but recently I had issues with the other caller not being heard & this is w/o Bluetooth. I've tried every suggestion to no avail, which sucks because I hate changing apps. I also tried Cube but had the same issue. I found True phone through a video on YouTube but the developer is a bit of a jacka$$ and there's no Bluetooth 😑.

All i have to do is flash the indonesian home.csc and I will get call recording and hyia call spam protection ? Exynos Variant here.

Do these options (call recording and call spam blocking) stay after reboot ?

[Samsung Galaxy S21 Ultra] neflictus:
Thanks, downloaded, trying now.

OEM lock is ON, FRP Lock is ON.

Is that an issue ? Can i flash HOME.CSC using ODIN ?

Do I have to change something ?

Will it trip Knox ?
[Samsung Galaxy S21 Ultra] neflictus:
Flashed only HOME.CSC, there weren’t any issues. Call recording works, call spam blocking works, stays on after reboot, some Indonesia apps are installed. I uninstalled them, debloated and everything is peachy. 5G stays on, there is Samsung Pay. Software update works.

Cheers and Thanks.

ciao io ho un s21 ultra g998b, se flasho con odin il firmware indonesiano avrò direttamente la registrazione delle chiamate nativa attiva, o devo fare qualcos'altro tipo resettare con la sim thl inserita??
[Samsung Galaxy S21 Ultra] neflictus:
You will have the recording option active (a Button will appear in the call app), so you can manually record. There is also an option to automatically record all conversations in the call settings.
[Samsung Galaxy S21 Ultra] ocaldini:
Exynos Brazil version (SM-G998B) ZTA/ZTO has native call working flawlessly.

I was very suprised cause the old recent mobiles didn't have and I had to change CSC via Odin.
[Samsung Galaxy S21 Ultra] zackleeuk:
Do Brazil have the Samsung Pay?
[Samsung Galaxy S21 Ultra] zackleeuk:
I flashed XID from UK BTU, call recorder/WiFi call/dual sim/hiya working perfectly.

Samsung pay won't work, the Samsung Pay come with XID seems like a local version not the international version Samsung Pay. The spay apk is different.

I tried to change CSC from AUT to XID or INS, both by samkey but without success. At the end samkey shows the CSC changed, but in place of XID or INS there is only EEA.

Any idea hot to fix this?
[Samsung Galaxy S21 Ultra] SHAHRULNIZAM30:
Hi, Following @carlitobahsoun guide, i'm happily to say that ive manage to get the native call recording function.

Except for some scare due to USB port loose during Odin downloading, the process is brief.

Anyway i downloaded the newest Indonesia firmware from Sammobile and flash all the files and use the HOME CSC to maintain all the data.

However i think by flashing all firmware (I'm from Malaysia), i wont get the OTA update later. I've experienced this when i flashed Indian firmware on my Note 10+ (Of course to get the Call Recording function- But not working) and there was no OTA until i checked in Sammobile the Indian firmware already got updated 4 times.
[Samsung Galaxy S21 Ultra] SHAHRULNIZAM30:
Why dont you try as per @carlitobahsoun guide?
[Samsung Galaxy S21 Ultra] SHAHRULNIZAM30:
I think that is Snapdragon, it wont be compatible with Indonesia firmware.

As i have a european s21 plus with exynos can you please tell me how to change to csc of Israel?
[Samsung Galaxy S21 Ultra] Sithlordpt:
I changed mine from MEO (Portugal) to THL (Thailand) with samkey and it was super easy. Got call recording instantly and Samsung Pay.

Just buy some credits in ebay, go to samkey and write THL in CSC. Start, wait and it's done.

Yes, it does.

You can start by reading the last posts of this thread.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Perhaps, I'm being lazy, but I just wanted to know: am I looking to just change CSC or flash new firmware -- what are the general hoops?
[Samsung Galaxy S21 Ultra] Sithlordpt:
If you want call recording, the only thing you need is samkey.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Even on the new S21U USA U1 Unlocked model?
[Samsung Galaxy S21 Ultra] Dave83:
Yes, but after wipe data Samsung Pay doesn't work and maybe something else too
[Samsung Galaxy S21 Ultra] Sithlordpt:
I think it works but you need to clean application data and use VPN. Portugal doesn't have samsung pay so it connects to samsung servers to check if you are in a supported country or not. The trick is similar to what you need so you can use Good Lock.

[Samsung Galaxy S21 Ultra] kkoonrad:
Have you tried Skvalex Call Recorder? Lots of people recommend it, although I haven't decided yet myself.

Can anyone confirm that it actually works properly? Not through the internal microphone. Does it work without root?

If it would work like that then I wonder why so much trouble.

PLS/PLS,PLS/PLS

version number: RP1A.200720.012.N975FXXU6FUCD

Can i flash XID, and activate call recordings? Do you know is XID also single CSC in Note 10+?

And if i will download firmware, i need to put all files to phone, or single HOME CSC via odin?

Thank You.
[Samsung Galaxy S21 Ultra] maxq1:
thank you so much for the tip, guys! went from GLB csc (Philippines/Globe) AUE1 to XID/XTC (Philippines/open line) AUE1. now i have call recording! just had to debloat some Indonesian-specific apps afterwards. everything works and recording is clear from both ends. curiously, i never got the pop-up asking to keep current carrier settings

PS/Btw,

here's a list of XID apps that i uninstalled. perhaps others can add to this

com.samsung.android.rajaampat

com.srin.fakfak

com.srin.indramayu

com.srin.garut

XID home_csc seems a lot smaller (no more than 200mb, iirc) than most of the same base (AUE1, ~1gb). is that all bloat?!?

if you're flashing just the home_csc from XID, i think it's important that the XID FW version you are flashing matches the one on your device. so if you're still on AUDA, it's safer to flash XID AUDA home_csc instead of XID AUE1. would be glad to know if others have successfully tried flashing a newer home_csc to a device with an older FW
[Samsung Galaxy S21 Ultra] denzel09:
Are you sure? What csc you have? Are you rooted?

I have an eu csc, no root, all stock and i have tried both SKVALEX and Call Recorder from Play Store but i can't listen what the other person says, the sound of voice is so so low that it's impossible to hear. What setting do you have used in Skvalex?
[Samsung Galaxy S21 Ultra] denzel09:
UP!
[Samsung Galaxy S21 Ultra] timofonic:
I'm from Spain. I want (and NEED) native call recorder, not annoying software thjat ALWAYS fail in one way or another. I also can't mute my microphone because the other side doesn't get recorded, for example. Bluetooth never worked for me too.

SKVALEX or Cube ACR has issues. No app has no failures at call recording. I tried tons of apps, I'm not a developer but a very stubborn user. Please stop doing astroturfing.

Do I need to install full ROM from Indonesia (XID) only to get full call recording (both manual and automatic)?

Or does it work by only installing home_csc? I see lots of speculation and experimenting, but not a clear answer about this.

Can it be possible to modify my home_csc to support these features?

Do I need to unlock the bootloader to change home_CSC and/or the rest of the ROM?

Does CSC change removes other features such as slower 4G and 5G connections or whatever?

Any brave soul willing to do a proper sticked post about call recording? Even better if other about CSC stuff, it would be greatly appreciated.

Thanks in advance.

I would like to ask the same question. I also have SM-G998U1 which is the international version with SD 888.

coz i cant change csc only via samkey and cant buy credit , that why my only way is to flash XID coz if u flash any multi oxm it detect sim card CSC and wont change , only XID coz its single OLE CSC not multi oxm .
