Awesom

TWRP is installed.

I simply tried it using the TWRP app first. I backed up the old Recovery.img and Boot.img beforehand (in case anyone reading this wants to follow a similar path). Then, I downloaded the latest TWRP version for my A52 4G and flashed it via TWRP. And that's it. Custom Recovery and Magisk root are on, and they remain even after a reboot and reboot into recovery.

First and foremost, I want to sincerely thank you, "parrots_" !

Even if it might not have been a big deal for you, it was still very important and helpful for me to have something like a guide for all the work. While I do enjoy venturing into such things myself, I probably wouldn't have tried it without someone telling me, "You can do it," for safety reasons. Thank you very much, seriously!

When rooting, I didn't encounter any issues with the Magisk/Topjohn guide (https://topjohnwu.github.io/Magisk/install.html#samsung-devices) anymore. During previous attempts (as mentioned in the earlier posts), either the flashing via Odin would be aborted or, even with successful flash attempts, I couldn't notice any changes after rebooting through Odin (both in the stock recovery menu and after ROM installation.

The system was still usable as usual, but I simply couldn't get root access. I can't exactly pinpoint the cause (probably some errors on my part). But I would recommend everyone to simply follow the guide from Topjohn/Magisk.

Download the latest official firmware, flash it onto the device, then patch the AP files of the EXACT same firmware you previously flashed using the Magisk app, replace the patched AP with the original one during the Odin flash again, and it should work without any issue.

(Of course, the disclaimer applies here too: All at your own risk!)

No problem, I was there at one point too, wanted to make sure I didn't break anything. And after all my research, I tried to unlock the bootloader, and the Android system got corrupted. Good to hear you didn't have the same issues I had with other phones.

I want to ask if anyone knows if the new Samsung S24 series can be changed to CSC for call recording without any problems?
[Samsung Galaxy S24 Ultra] Sk.akram:
Probably yes, but you should wait for some time.
[Samsung Galaxy S24 Ultra] Svettel:
Yes, i did it with Samfrp tool.
[Samsung Galaxy S24 Ultra] Rapier:
I did it on my S23 Ultra with SamFw and should be possible on S24 series too. We will have to wait till someone will get one and test to be sure...
[Samsung Galaxy S24 Ultra] Svettel:
I did it on 24 Ultra. I changed to csc TUR to ILO. I Got the phone already.

EDIT : 5G IS WORKING

Your question made me curious regarding 5G, so especially to test that i went to the area where there is 5G connectivity and i can confirm that after changing CSC from EUX to INS, 5G is working.

P.S. You need to activate Promotional 5G Pack first in Airtel App.
[Samsung Galaxy S24 Ultra] Vadim1:
Both EUX and INS belong to OXM, right?

What is exactly the purpose of this icon?
[Samsung Galaxy S24 Ultra] farhankzs0:
Help...!

Yesterday, I bought S24 Ultra (928B/DS, Singapore, CSC was XSP probably) which didn't have call recording feature. So my friend used Samfw & changed the CSC to XXV (Vietnam) to bring call recording option. Everything looks okay but the April update is yet to arrive. It is showing the last update as march, which came out of the box by default.

Now my question is:

1. Should I go directly from XXV to other CSC (i.e. INS) to get faster updates? Or I must go back to default CSC & then again go for any other CSC?

2. Is there any complications I might face if I repeatedly change CSC?

3. Which CSC is best at this moment regarding network & data connectivity & features?
[Samsung Galaxy S24 Ultra] xdauser2024:
When you tap on it, it opens up a player to playback your recorded voice call from.
[Samsung Galaxy S24 Ultra] nguyenlucky:
You have to flash latest Vietnamese firmware to get OTA afterwards. Even though a lot of regions share OXM multiCSC, some regions have different firmware versions, leading to no OTA if chnaging between their CSC.

For example, your current firmware AXBG does not exist for XXV (they have AXBN instead) hence no OTA.

1. XXV is reasonably fast. Do as above and you will have OTA.

2. Regarding software errors, no, changing CSC won't have any consequences. But changing CSC too many times consecutively will cause you phone to heat up a lot, due to constant reboot and reloading software features, which is certainly not good. Change 2-3 at a time, give it a break before changing again, if you want to experiment with multiple CSCs.

3. No idea, it largely depends on your country and carrier. Best to ask someone with the same phone in your area.
[Samsung Galaxy S24 Ultra] farhankzs0:
Thanks Man...!

Regarding point 1, Do I need to go back to the default CSC from current XXV to change it again? Or I can directly change from XXV to INS (i.e)

Regarding point 3, I'm at Bangladesh (Beside India), should I stay with XXV or move to INS?

& One last thing (as I'm a fast learner but new in this process), can you please share me the process of flashing firmware? (any tutorial or video link would be much appreciated.)
[Samsung Galaxy S24 Ultra] nguyenlucky:
You can change CSC to whatever you want, within OXM actually.

If you're in Bangladesh, probably INS is better.
[Samsung Galaxy S24 Ultra] farhankzs0:
Thank you, brother. You're a life saver. Right now I'm at INS CSC and updated latest firmware with ODIN.

[Samsung Galaxy S24 Ultra] balavigneshyolo:
Changing the CSC on your S24 for call recording is dangerous. It might work, but it could damage your phone. Instead, consider using built-in options, call recording apps, or carrier services.
[Samsung Galaxy S24 Ultra] dvhttn:
Explain why and how this damage can occur....
[Samsung Galaxy S24 Ultra] itad:
Ich habe gestern die CSC geändert und alles TOP man muss natürlich alles genau lesen wie es gemacht werden muss
[Samsung Galaxy S24 Ultra] devaponnadsm:
Wrong information. It is NOT dangerous. Call recording apps are unreliable and might not work always. The best way is to change CSC by just flashing in Odin, just a < 5 mins process.
[Samsung Galaxy S24 Ultra] e.kabashi95:
This is also wrong info, odin itself can't change csc.
[Samsung Galaxy S24 Ultra] devaponnadsm:
Flash new region firmware CSC (not HOME_CSC) using Odin
[Samsung Galaxy S24 Ultra] e.kabashi95:
This will not change csc will ony wipe your data.
[Samsung Galaxy S24 Ultra] devaponnadsm:
Are you sure? Pretty sure I changed it like this in A54 from MEA to INS. In S24U, I flashed Custom ROM.
[Samsung Galaxy S24 Ultra] e.kabashi95:
100% sure, ask others too they will explain.
[Samsung Galaxy S24 Ultra] devaponnadsm:
I flashed the INS complete firmware, this wipes data and changes CSC. I'm sure it was MEA.
[Samsung Galaxy S24 Ultra] e.kabashi95:
Try to change with this method to EUX then you will get a clear answer.
[Samsung Galaxy S24 Ultra] Mon3T3R:
Hello guys

I'm new to this side of things and would like to ask you about what's going to happen to my device, I bought a S24 U with its latest update being S928BXXU1AXCA and changed its CSC to THL, I would like to know if I'm going to encounter any issues regarding OTAs in the future and if I'm going to encounter the said issues, what CSC do you guys recommend? I'm not sure what was my default CSC... I just want to access call recording and have OTPs in the future.
[Samsung Galaxy S24 Ultra] TODI1111:
I switched csc from EUX to ILO and the OTA updates arrive fine.

I got a canada's version mobile S24 with SM-S928W but when i see list at https://samfw.com/firmware/SM-S928W, i could not found any other countries version and so how is it possible to change CSC for call recording ?
[Samsung Galaxy S24 Ultra] Cloud Strife 48:
Man, I feel bad for you guys as ya'll still using Odin just to change CSC. There's much easier way tho and you can do it like in a sec. only. But as long as ya'll successful in changing your CSCs then it's good. Don't worry about OTAs, you should still be able to get them. :)
[Samsung Galaxy S24 Ultra] Cloud Strife 48:
Yes, you are correct. Choosing CSC instead of Home CSC will not only clean wipe all your data but also changes your current CSC to a new one.

Oh, this is really bad. I didn't know about this. I need to tell all my friends not to buy S24 from Canada.
[Samsung Galaxy S24 Ultra] atulhansaliya:
Samsung should activate features based on the chosen region during setup, not based on the manufacturing region.
[Samsung Galaxy S24 Ultra] Denissxx:
Is the call recording on ILO csc automatic or you have to turn it on manually on every call?
[Samsung Galaxy S24 Ultra] TODI1111:
You decide how you set it up. It can be automatic or manual.
[Samsung Galaxy S24 Ultra] nguyenlucky:
Call recording without informing the other party is illegal in some countries, they cannot legally do it.

I have used this guide to successfully change my S24U CSC MID(UAE) to INS.

Call Recording, CallerID and Samsung wallet(SPay) are working.

*No data wipe. It's just 2-3min work.

There's a slight change in software:

For USA folks, ACR Phone works for call recording. It requires the ACR Phone app as well as the ACR Phone Helper, which is available in the Galaxy store.

Been using it for years.

I'm on INS from a long time (S24U, S23U, ...), just check some longer calls (local operator allows up to 60 minutes) - all long recordings are fine (Samsung even enable VoWiFi recording on UI 6.1).

I know for at least 7 S24 (Ultra, S24+ and S24) that was on THL XE4 which report Google Pay "problem" with latest Google Play Update from 1 May 2024, most of them already downgrade to XD5 and wait for next firware (after XE1), most probably it will be XE8 and will be again united for (EUX, THL, INS, XXV, ILO and and other OXM MultiCSC)

You are the only one without "problem".

Are you with latest Google Play Update from 1 May 2024?

Yes, latest google play update as well

Guys just to double check whether INS is OK also with gpay, gp certiified ? For whatsapp recording CubeAcr ? About to purchase s24u, I did this csc change process several times with previous devices but using payed samkey.
[Samsung Galaxy S24 Ultra] ChoSmile:
S24* (SM-S92*B Europe/Asia model)

EUX - XD6 GPay works

INS - XD5 GPay works

XXV - XD5 GPay works

ILO - XD5 GPay works

THL - XE4 GPay not works (for over 7 reports, except for one user that said that works).

S24* (SM-S92*U, SM-S92*U1 US models, SM-S92*W Canada model)

There is no CSC that support Call recording

Samkey (paid) - still works for "CSC change"

SamFw (free) - still works (a lot of virus warnings)
[Samsung Galaxy S24 Ultra] Ing.King:
CSC INS is the way as always :), btw. tried CubeACR but whatsapp recorded only my side clear, other was unusable. Anyone knows what setting to use for "VoIP recording audio source", Voice recognition (software) does not work. I guess it is a lottery, will try to change other options and check which one would work.
[Samsung Galaxy S24 Ultra] diabel78:
Hi

I have the same situation (CSC set to THL, XE4 software and G Pay problem).

What do you suggest in this situation?

Wait for software update/unification/whatever?

Change CSC to INS, or revert to EUX?

I just don't want to mess up more than now ;)
[Samsung Galaxy S24 Ultra] ChoSmile:
Same questions several times - same answers.

Change CSC to ANY CSC will NOT fix GPay.

Flash XD6 or wait for XEA or even most probably XF2.
[Samsung Galaxy S24 Ultra] diabel78:
Thanks for the answer.

As I understand it, it is impossible to say how long I have to wait for suitable software? Weeks? Months?

In case I decide to downgrade to XD6, should I chage CSC, to prevent update back to XE?

And it is possible to flash without data wipe?

I'm sorry for what may be trivial questions, I'm just a new here.
[Samsung Galaxy S24 Ultra] ChoSmile:
No schedule. Normally once a month but there was 3 or 2 in a month or 1 one on 3 months.

In not change - features (call rec) will work. OTA will not work. (if changed - oposite).

READ, READ, READ !!! BL,AP,CP,HOME_CSC do NOT wipe/reset.
[Samsung Galaxy S24 Ultra] redcom7:
i tried to flash xd6 with samfw FRP odin section (odin didnt work...)

and the phone stuck on download mode ... it stuck and fail when AP was on progress...

any ideas ??

my phone seems bricked and stuck on download mode
[Samsung Galaxy S24 Ultra] redcom7:
I flash again and finally my device became alive but wiped off
[Samsung Galaxy S24 Ultra] ChoSmile:
ODIN app and "odin section of samfw" are different tools to flash but better use ODIN app!

If stack on download mode (or other) - phone can be restarted by holding "power" and "vol" dor 7+ seconds.

flashing with BL_, AP_, CP_ and CSC_ files - wipes the phone.

flashing with BL_, AP_, CP_ and HOME_CSC_ files - updates the phone.
[Samsung Galaxy S24 Ultra] redcom7:
That was my mistake...Odin section of samfw was a disaster...and phone could not get out of download mode even by pressing power and voldown...

Odin many times gives "no response" when loading the Ap section...

Anyway my device is fresh and I changed CSC to EUX get the latest update and back to THL... everything works Great now....

Guys anyone with INS CSc has the latest update 1.6. XED ?

I can see available FW in samfw DB but Phone does not offer an update
[Samsung Galaxy S24 Ultra] ChoSmile:
What is your current FW?
[Samsung Galaxy S24 Ultra] Ing.King:
XD6 security 1.5. Original CSc eux

There is no XD6 for INS this May be the problem ? I guess switch back CSc to EUX update to last fw and back to INS ?
[Samsung Galaxy S24 Ultra] Ing.King:
Well done, change to eux update right away then back to ins, another happy customer. It would be nice to avoid such procedure every month although it is matter of 3 mins. Probably flash via odin to INS would make the miracle right ?
[Samsung Galaxy S24 Ultra] x7nofate:
How to check 1.6 XED?
[Samsung Galaxy S24 Ultra] Ing.King:
1.6. - day and month of security update, XED - firmware version suffix.

Full FW : my original (during purchase of device) CSC EUX S928BXXS2AXD6 (security 1.5.)

Latest for EUX: S928BXXS2AXEF (security 1.6.)

Latest for INS: S928BXXS2AXED (security 1.6.)

My assumption, while CSCs are not sharing the same suffixes and you switch to another CSC like I did, I could not expect to get updates as INS does not exist in version XD6, therefore prerequisity / mandatory is not met and there is no way how to upgrade from EUX XD6 to INS XED, only from EUX *XD6 to EUX *XEF.

Correct me If I am wrong.

It is bit weird, in the past I had Note 20 Ultra, S21FE both with changed CSC and this was not the issue there, I got updates without any tweaks. I did small research, both N20 Ultra and S21 FE shared identic FW version for both SEK(Ukraine)/INS(India) and original TMS/TMS CSC. That is the reason why updates arrived without any tweaks.

Hope this help anyone else with delayed / never arriving updates after CSC change.

If you check complete DB of samfw for : S928BXXS2AXEF just filter XEF

you find only CSC (EU countries flags) where call recording is not allowed, means 3 mins every month to obtain latest FW, or persuade myself to ODIN completely INS FW.
[Samsung Galaxy S24 Ultra] x7nofate:
Yes, I have INS CSC and 2 days ago I got software update with 1.6 XED
[Samsung Galaxy S24 Ultra] Ing.King:

This is my first Samsung, I changed the CSC from EUX to THL but I see that both are noted, THL/EUX.

​
[Samsung Galaxy S24 Ultra] ChoSmile:
Download XED INS files and use ODIN to flash with BL_, AP_, CP_ and HOME_CSC_ files - to update (without data loss).

(Using CSC_ instead of HOME_CSC_ in [CSC] will reset it.)
[Samsung Galaxy S24 Ultra] ChoSmile:
First one is important - Active CSC.

Features shown/hidden depends on it.

OTA also comes when released for this CSC.

And because there is no ...XD6 firmware for THL CSC - you will not receive OTA.

(fix it by odin flash with thl files - discussed several times)
[Samsung Galaxy S24 Ultra] NOSS8:
Ok,So it displays the 2 (THL/EUX) and the first corresponds to the current CSC version and the 2nd the original one?
[Samsung Galaxy S24 Ultra] ChoSmile:
Active CSC / SIM 1, SIM 2 / Region / Primary CSC

Only first can be changed and Important!

Next two are switched by phone depending active.

Region and Primary are market dependent by manufacturing.
[Samsung Galaxy S24 Ultra] nguyenlucky:
Last one is important as well. If the last is not EUX from factory, changing the first to EUX will not have OTA even if firmware matches.

ODIN flash with BL, AP, CP and HOME_CSC files from (...XFC) INS, XXV or ILO fw

Also CSC change to one them (they are on same channel), so OTA will work, GPay works too.

3.

Flash with EUX (...XFE) BL,AP,CP,HOME_CSC. No CSC change. It will be on THL channel but with EUX files, so GPay works and no OTA. On next THL must flash again.
