Hi. I confirm changing from XSA to INS/ILO/XXV cannot enable SIM2 option, but I did not factory reset. By the way, do you know which CSC can enable 5G SA and VONR option, as Xiaomi can enable these by using dial code.
[Samsung Galaxy S24 Ultra] sealed:
Hello. Does anyone know which CSC can enable 5G SA and VONR option? Xiaomi can enable these by using dial code, I don't know where I can find these options including developer options.
[Samsung Galaxy S24 Ultra] nguyenlucky:
No idea, we don't have VoNR in either Oz or VN 😆
[Samsung Galaxy S24 Ultra] sealed:
Have you ever seen 5G SA in Oz? I noticed Telstra and Optus have 5G SA by searching Google, but I have always seen 5G NSA.
[Samsung Galaxy S24 Ultra] nguyenlucky:
Sorry I'm not sure either.
[Samsung Galaxy S24 Ultra] renek11:
I almost forgot to confirm this information that this app works for me in Europe as well. The disadvantage is that it does not record calls made via bluetooth headset, but the advantage is that it also records calls made via WhatsApp, Messenger etc.
[Samsung Galaxy S24 Ultra] behemot24:
I changed to INS and Samsung Pay does work and everything else also looks fine.
[Samsung Galaxy S24 Ultra] x7nofate:
Good I never had any issue with INS either. Some other user where complaining Samsung pay doesn't work with INS but probably he try to link bank which is not supported by Samsung pay
[Samsung Galaxy S24 Ultra] kingracer:
Hey all, I've read the whole thread and seen some message about disappearing auto-download option from system update menu. Is there any other negative consequences of CSC change that anyone got? Bcuz I want to use ILO CSC, as I was doing on S23U, but here I'm still not sure if it won't break anything... thanks!
[Samsung Galaxy S24 Ultra] DeaDman594:
Thank you So much I did it and it's working fine.
[Samsung Galaxy S24 Ultra] kingracer:
So I've changed csc to ilo and it's really missing auto-download option now in system update menu. And I'm worried if this means that system updates won't come at all
[Samsung Galaxy S24 Ultra] x7nofate:
Change CSC to INS you won't have any problems. I do not understand why people have so much obsession with ILO CSC
[Samsung Galaxy S24 Ultra] kingracer:
Idk, I was using ilo on s23u by recommendation, and it was fine. No 3rd party apps or weird calendars, and call recording+spam detection working. Is it the same on ins? And what about update frequency?
[Samsung Galaxy S24 Ultra] x7nofate:
I had INS for 2 years in my note 9. No issue at all. Everything working. Now I got INS in s24 ultra and again no issue everything working: Samsung health, wallet, Samsung Pay, Dual Sim, spam detector, phone calls recorder etc.
[Samsung Galaxy S24 Ultra] zimmen:
Went from EUX to INS and now single press on words doesn't work so you get information, and sms takes a crazy long time to arrive, also has problems with the coverage sometimes as it doesn't want to stay on 4G, is even so that you can see the 4G icon flashing.

So back to EUX and then try to find another one that has Call Recording working
[Samsung Galaxy S24 Ultra] twinkyz1979:
i can't get the hidden menu to work on my s24 ultra does anyone have a work around?
[Samsung Galaxy S24 Ultra] sebastan:
There are no new rules to enable developer mode. It's been done the same way for years. If you already run it and can't enable USB debugging, turn off "auto lock" in the settings.

Another topic is the choice of CSC. Recently I spent time in an area where 5G in the C band has already been launched. I had CSC ILO running. Telefeon logged in to 5G, but NSA, with speeds of 50-100 Mbps. After changing to EUX, the speeds exceeded 800 Mbps, already in the C band, of course. After changing to INS, about 600 Mbps, but these differences could have been temporary, there was also the C band. Have you noticed any differences in the operation of your phone depending on the CSC?
[Samsung Galaxy S24 Ultra] twinkyz1979:
I found the answer I was looking for here. The only problem is even after doing this method of changing the CSC and rebooting I get prompted with another reboot to switch my provider. After that happens and I check my mtp info I am back on VZW. No matter what i select this is what i always get.

S24 Ultra

SM-S928U1
[Samsung Galaxy S24 Ultra] JustTresk:
I used the youtube video on page 6, and change from EUX to INS.

and call recording works fine now. even with BT headset.

But am i forced to use the original samsung call app only, or is there any other alternatives that will work?

i tryed if Truecallers recording work, but no.

Samsungs call app need to be the standars call app, to get record to work on it.

[Samsung Galaxy S24 Ultra] nguyenlucky:
U/U1 devices change CSC based on your current SIM card, if you live in the US and use US carriers. I'm not sure how to disable that behaviour
[Samsung Galaxy S24 Ultra] sealed:
Hi. Are INS and EUX running on 5G SA?
[Samsung Galaxy S24 Ultra] sebastan:
I think I should clarify, because I should probably use 5G in the C band instead of SA/NSA, and it doesn't necessarily mean the same thing.

From my observations, INS and EUX behaved the same. So in the same place, if the speedtest showed e.g. 800 Mbps on EUX, it did the same on INS, and on ILO e.g. 150.

I haven't had enough time to analyze the frequencies used in detail yet, especially since there is 5G where I live, but not in the C band.

It would be ideal to have two phones with different CSCs, but changing them every now and then, although fast, is not convenient.
[Samsung Galaxy S24 Ultra] x7nofate:
Those who change csc to INS, are you able to receive OTG updates?
[Samsung Galaxy S24 Ultra] jemcik:
I changed my CSC from EUX to ILO when received my Ultra (about 3 weeks ago) and today received an update, everything works fine, call recording too ☺️
[Samsung Galaxy S24 Ultra] melkorbcn:
Can you show me youre app configuration to works well please?
[Samsung Galaxy S24 Ultra] renek11:
Install and use. No special settings
[Samsung Galaxy S24 Ultra] AltairJr:
You have to disable the cidmanager to prevent the CSC auto switch due to sim card.

Open up ADB use the below command.

adb shell pm uninstall -k --user 0 com.samsung.android.cidmanager

I got this info from this reddit post years ago

[Samsung Galaxy S24 Ultra] Berrada005:
Hello everyone!

Is it going to work if you flash a rom stock through ODIN without changing SCS?
[Samsung Galaxy S24 Ultra] nguyenlucky:
No, you need to change CSC
[Samsung Galaxy S24 Ultra] nguyenlucky:
Hi, can you try changing CSC to WWD (demo CSC) and see if SIM 2 is enabled and eSIM is disabled?

I used to owned an Aussie S23U and it behaves like that. Note that OTA will be disabled as well, but everything will be normal when you switch back to a normal CSC.
[Samsung Galaxy S24 Ultra] sealed:
Hi, I tried to change csc to WWD, esim that I previously add still working but I don't know if sim 2 is available because I don't have dual sim slot. Fortunately, s24 xsa support dual esim, better than s23.
[Samsung Galaxy S24 Ultra] nguyenlucky:
yeah, I live in AU but went to an SEA country and get s24 s928b/ds, dual physical sim plus dual esim and full compatibility with aussie networks
[Samsung Galaxy S24 Ultra] sealed:
Maybe in the future I will buy a dual sim slot to save this evil au version. By the way, I also find an interesting thing by using QPST that different CSCs have different band combo restrictions, which may affect support band and CA in 4G and 5G.
[Samsung Galaxy S24 Ultra] rolandyip:
SM-9280 phone supported csc BRI and TGY only , try manually key csc with ILO SamFW tool show successful.

But after phone reboot remain BRI csc. any help without root phone?

Tks.
[Samsung Galaxy S24 Ultra] nguyenlucky:
no you can't use any other CSCs, only these two BRI and TGY.
[Samsung Galaxy S24 Ultra] nguyenlucky:
True, that's what I thought as well, matching CSC to where you live is the best. Even though I lose call recording by using XSA CSC, full network compatibility is more important I guess
[Samsung Galaxy S24 Ultra] xdauser2024:
I think it's ok. I just changed my CSC from KSA to ILO on my S23 Ultra and that option is missing for me as well. A YouTube comment said the same as well.
[Samsung Galaxy S24 Ultra] xdauser2024:
Don't worry. I did this on my S23U and before changing my CSC from KSA to ILO, I had a pending OTA update. After changing my CSC, that OTA update was still detected as available for download. By changing to ILO, my Auto download over wifi option was also gone.

ILO does a couple of more tweaks to System updates like not reminding you every 24 hours if you have a pending update or on every reboot and doesn't show "Update available" at the top of the settings app where "settings" is written in large font. Also, the orange dot to indicate a pending update is not shown on the Update section in settings app.

Personally I like these changes as they make pending system updates much less obnoxious and intrusive.
[Samsung Galaxy S24 Ultra] kingracer:
I forgot to follow up, I've also got 2 updates since csc change to ilo already, so everything seems to be fine :)
[Samsung Galaxy S24 Ultra] klisza1993:
I did change CSC from PLS(poland) to EUX - and I don't receive OTAs...
[Samsung Galaxy S24 Ultra] nguyenlucky:
Non-EUX devices won't have OTA after changing to EUX.
[Samsung Galaxy S24 Ultra] dvhttn:
Is there some more information on changing csc and being able to receive OTA updates anywhere? For those of us that have changed, if we know we will not get OTA updates we won't waste time waiting for them to arrive.

Thanks.
[Samsung Galaxy S24 Ultra] nguyenlucky:
If your device is not EUX from factory, don't bother changing to EUX and expect OTA. There hasn't been a fix yet.

For other regions, you just need to make sure the BL, AP, CP and CSC version on your phone matches with the new CSC (you can check on Samfw)
[Samsung Galaxy S24 Ultra] dvhttn:
My phone is EUX from the factory - just went to an ILO csc for call recording.
[Samsung Galaxy S24 Ultra] sealed:
Hi. I was wondering how many physical sims shows when you remove them (grey) in sim manager.
[Samsung Galaxy S24 Ultra] nguyenlucky:
For Aussie B devices, only one.

For B devices in other regions, two.

The funny thing is, my SEA S24U still retains dual physical SIM (two grey empty sims when removed) even when I change CSC to Aussie unbranded (XSA).

Fk Samsung Australia :mad::mad::mad:
[Samsung Galaxy S24 Ultra] sealed:
yes, it seems there is only one grey sim icon even if I change to WWD. Have you done factory reset after you change?
[Samsung Galaxy S24 Ultra] RKSTN:
I have changed my S2 Ultra's CSC from BTU to INS.

This may help if you are new to this: https://technastic.com/change-csc-samsung-devices/
[Samsung Galaxy S24 Ultra] RKSTN:
Yes, changing the CSC can enable the call recording feature! :)
[Samsung Galaxy S24 Ultra] zimmen:
So i have to use ILO or INS to get the native Call Recorder on EUX? Is there no other way to get?

Missing some things from EUX when I tried
[Samsung Galaxy S24 Ultra] drpo:
Hello. All the manuals I checked say about unlocking CSC using the ADB tab. I don't see it here. Is this a bug or maybe the latest version of SamFwTool has changed the location of this function and it is done using the MTP or ROOT tabs?
[Samsung Galaxy S24 Ultra] dvhttn:
Yeah, I spotted that too. Use the root tab if you're rooted ... otherwise use the mtp tab - worked for me with my unrooted phone.
[Samsung Galaxy S24 Ultra] nguyenlucky:
I don't own an Aussie S24u so I can't try that. However, I did own an Aussie S23u a long time ago, on OneUI 5.1, changing to WWD removes the SIM manager altogether. Dual physical SIM works but eSIM and OTA stops working.
[Samsung Galaxy S24 Ultra] hoss_n2:
One thing I noticed from changing CSC from EUX to INS is 6GHz "Tri band" WiFi hotspot is now gone / Not supported on INS CSS
[Samsung Galaxy S24 Ultra] nguyenlucky:
Indian government hasn't approved 6Ghz yet. Same as XXV (Vietnam). THL (Thailand) has call recording and 6Ghz.
[Samsung Galaxy S24 Ultra] x7nofate:
What 6GHz tri band does?
[Samsung Galaxy S24 Ultra] nguyenlucky:
Sharing wifi in 6GHz mode. Best speed but worst range. However many countries haven't approved 6Ghz yet, including India (INS).
[Samsung Galaxy S24 Ultra] Da170:
I'm in the USA with a S24U, and CSC change button in SamFw tool doesn't list any options with call recording, only USA options.

Can I flash a new firmware that will support it? Mine CSC is VZN. Model SM-S928U.

Also if I do that how can I still receive auto updates?
[Samsung Galaxy S24 Ultra] benice275:
Hi, Anyone using model B in Canada with CSC IND / INS / ILO getting 5G or any issue with 5G on Rogers or Talus ?
[Samsung Galaxy S24 Ultra] gopala krishna:
I am in India with Unlocked US S24 Ultra(SM-S928U1). The CSC list only shows codes for North America.

Is there any way i can change the CSC to INS or any global CSC so that I can have Call recording and Samsung Wallet (Indian version preferably) and OTA, would it work with INS?

Can I just type INS and would it work?
[Samsung Galaxy S24 Ultra] gopala krishna:
Have you changed the CSC? If so, did it work?

I have unlocked version and wanting to change the csc so i can have call recording. But I'm worried if this would trip knox and or brick the device.
[Samsung Galaxy S24 Ultra] nguyenlucky:
No you can't, use ACR from Galaxy Store

No you can't, use ACR or sell it and buy S928B/DS.
[Samsung Galaxy S24 Ultra] gopala krishna:
Thanks for your response. Well ACR is fine for the time being but it won't record when using Bluetooth devices tho.
[Samsung Galaxy S24 Ultra] Vadim1:
Using B/DS version (OWO).

Not getting 5G with any provider tested (Rogers, Telus, Freedom).

I found here https://www.samsung.com/sg/support/...s-that-support-5g-for-samsung-galaxy-devices/

interesting notes

Access to 5G service may not be available when using foreign 5G networks outside the country of initial release.

If I get it right, it means we will not get 5G in Canada no matter which firmware one will use.
[Samsung Galaxy S24 Ultra] nguyenlucky:
Try OXM CSCs like EUX, XXV, THL...
[Samsung Galaxy S24 Ultra] Da170:
Yes this is also my problem with ACR, no Bluetooth recording.
[Samsung Galaxy S24 Ultra] useraa:
I was using SKVALEX previously with my Note 10+ but it doesn't work with S24 Ultra. I changed CSC and enabled call recording but CSC based call recording cannot record VOIP calls so bought ACR and now I can record both normal and VOIP calls. I have reverted back to my default CSC as ACR is working well for me.
[Samsung Galaxy S24 Ultra] efkosk:
ACR Phone or CubeACR please?
[Samsung Galaxy S24 Ultra] efkosk:
Since S20 I have been using the CSC change. I have been switching from EUX to ILO for the last 2 years. Since I have S24 base and S24 Ultra I have a signal problem. People can't call me and I can't call them. It happens to me quite often per day. The phone pretends to have a signal, even 5G is lit.

I have complained 2x about S24 and 2x about S24Ultra.

I am already clueless and I just tried to switch from ILO back to EUX and with 5G I get 5x faster speed on EUX on speedtest at the same place! So I suppose my signal problem will disappear.

Is this a coincidence?
[Samsung Galaxy S24 Ultra] renek11:
CubeACR
[Samsung Galaxy S24 Ultra] efkosk:
And did you change anything in the settings?

Is the sound source a microphone? Recording of the other side will not be very good quality

thx.
[Samsung Galaxy S24 Ultra] useraa:
CubeACR

Left it on default settings of "Voice recognition"

Recordings are pretty good (have not tested bluetooth recording) and best thing is that it can record two way calls from apps like whatsapp, imo, teams, zoom, google meet, etc.
[Samsung Galaxy S24 Ultra] xdauser2024:
I have a question.

If you have native call recording enabled, your calls' audio files are saved to /Internal storage/Recordings/Call. Calls that have been recorded show a small microphone icon next to it in the phone app's call log section.

So if you manually move the file out of that folder and move it back, the microphone icon disappears from the call log for that specific call.

Is there a way to link back moved recorded call files back to their original call log listing? I've cleared cache and restarted the phone app, even restarted my phone but with no luck.
[Samsung Galaxy S24 Ultra] mustakim_1994:
Edit : I got it working. It was my bad that I forgot to enable debugging mode. Once I enable Debugging mode and connected again in PC, samFW showed me the list of all the available CSCs. I selected mine i.e. INS and within 2 mins my phone rebooted and I got mine desired CSC.

Just got my S24 ultra SM-928B/DS. Its from UK and has EUX as Active CSC code.

I downloaded INS firmware with multi-csc OXM version and flashed it but noting change. It is still showing me EUX as active CSC code and also i am not seeing any other CSC in available CSC code. Any help??

P.S. i have flashed CSC and not HOME_CSC file while flashing

What does it say under settings about phone software service provider software
[Samsung Galaxy S24 Ultra] dvhttn:
No need to reload any firmware, download the Samfw tool ( ... https://samfw.com/blog/samfw-frp-tool-1-0-remove-samsung-frp-one-click ...) and follow the instructions to change csc. BUT ... firstly read more threads/posts on here as I'm sure I posted something as I was having problems at first. Works a treat once I got it sorted. Running ILO personally.
