No need for Odin. If he got the update via ota as he said, he will continue getting them via ota. After a csc change people should verify they are on correct version for the new csc in order to keep getting ota that's all. If they are on a version that's not supported on the new csc they need to use Odin once to get the current version for the new csc. After that they will get ota as usual.

Cheers.

Guys is there a chance that the CSC change to INS broke my phone? I got CTS profile match fail when running YSNAC and I can't use Google pay cause security reasons. My phone is not rooted the only thing I have done is open the programmer settings but that was a long time ago. Any help would be much appreciated!
[Samsung Galaxy S22 Ultra] billa:
Unfortunately changing the CSC may cause issues depending on the country/region it's being used in.

Instead flash it back with your local CSC firmware, and try a third party call recording app without changing CSC (it may or may not work in all regions).
[Samsung Galaxy S22 Ultra] arpcpro:
@Sherlock29 An independent recording app probably won't work with your local CSC. Just try to clear the user data and cache of the app Samsung Wallet/Pay. If it doesn't work, maybe a factory reset helps. I wonder if YSNAC was working with your original CSC. Did you change the CSC using samfw?
[Samsung Galaxy S22 Ultra] Sherlock29:
I had the same issue 10 months ago, i did everything included factory reset and stock firmware with odin and i still had the cts profile match problem. I ended up going to a samsung store and somehow they fixed it. After they fixed it i changed again the CSC to INS. Everything was working fine until yesterday i noticed i couldn't pay again and i checked YSNAC. I 've tried clearing cache but i have still the same problem. I did change CSC with samfw yes. I tried using CSC EUX and EUY again but that didn't fix the issue ether. I don't know ufnortunatly i have a very rare problem because i can't find anyone else with the same one. Every other guy with CTS profile match is talking about Magysk and rooted devices when i never rooted my device, I changed only CSC. If nothing works i have to go to Samsung again i guess...

About S23 series GPay problem explaind here (and possible sulutions):

S23 - call recording - possibility of changing CSC ?

I know the question is probably too early, but it is essential for my pre-order:D Does anyone know if it will be possible to change the CSC and activate call recording in the S23? (...

xdaforums.com

Someone reported, that Google maybe release a PlayProtect update, but I can not confirm:

try first:

System Google Play update can fix it. Check: Settings > About phone > Software information > Google Play system update

and check with YASNAC if still Fail
[Samsung Galaxy S22 Ultra] Sherlock29:
Thank you for your help! I flashed with odin to XDF (home_csc) cause even though i had EUX CSC I didn't get OTA update. Thank god this time this fixed the problem. I love the call recording feature so I will change again CSC to INS, hopefully it doesn't break again.
[Samsung Galaxy S22 Ultra] ChoSmile:
Yes, callrec/callid/spay/digikey will work if change now to INS. OTA will not work. On next EUX, switch to EUX update OTA and again to INS.
[Samsung Galaxy S22 Ultra] RKSTN:
This trick works only if you switch to one of the CSCs available under a multi-CSC. 👍

A question:

Does anyone know about this CSC?

https://www.reddit.com/r/GalaxyS21/comments/xejddv
[Samsung Galaxy S22 Ultra] ChoSmile:
XAA is USA unlocked (non operator) CSC.

For all US models (SM-****U) there is NO CSC that have "Call Recording" feature enabled. So, can not change/switch/flash to enable it.

Just in case i download sek firmware and I flash via Odin....

although Odin says pass everything goes right the firmware does not change...it stays to Ilo....any idea about this?
[Samsung Galaxy S22 Ultra] gpap2004:
All these firmwares ( ILO, SEK etc ) are part of the same OXM multi-firmware, so csc can't change through ODIN ( you can easy notice the csc with code S908BOXM1AVBF for instance. Any other firmware has the same initials OXM in it.

Only the Indonesian firmware has OLE and only this XID csc could changed via Odin. But now XID firmware is in snapdragon models ..

So , the only way to change the csc is through Samkey.

Be careful, not update to the newer version of firmware S908BOXM1AVBF, before you decide what csc want. Otherwise Samkey may not work to newer firmware.

Now, if you want to change csc with samkey, make a reset and then give it a try again

Anyone tried changing CSC for their US Snapdragon S22 with Thailand or India?

How to find exactly csc SEK for my phone I don't want brick my phone
[Samsung Galaxy S22 Ultra] gpap2004:
You don't need to find any SEK firmware. You only need to choose SEK in Samkey app. You need to be familiar with samkey processes.
[Samsung Galaxy S22 Ultra] tomesiek:
You need to use SamKey it will cost you one credit (you can purchase on ebay). Strongly advice to read how to do this. It take 5 to 10min.
[Samsung Galaxy S22 Ultra] Diac799:
Can some form UK and do this on s22 ultra can guided me🙂 first my attempt is fail because I do something wrong
[Samsung Galaxy S22 Ultra] Diac799:
Thank you so I need to wait , how can I know they update, can I check somewhere information about update Samkey ?

S908BOXM1AVBF this I have
[Samsung Galaxy S22 Ultra] gpap2004:
Hmm, I'm not sure if BF is supported
[Samsung Galaxy S22 Ultra] Walhalla:
Is changing the CSC really supported by Samkey for the S22 Ultra? When I check the model number (S908B) on their homepage it says: "This model is not supported"
[Samsung Galaxy S22 Ultra] gpap2004:
If you search some post back here you can read that although the page says not supported, in fact it is supported. We already did it but with the initial firmware A7. I don't know if the new firmware BF is still working
[Samsung Galaxy S22 Ultra] venki5star:
What will happen to the future firmware updates? Also Samsung Pay & Google Pay
[Samsung Galaxy S22 Ultra] Walhalla:
yeah, sorry @gpap2004 I have just seen the older posts.

my phone displays the following atm:

when I change the CSC with Samkey to EUX the last bit will be changed to EUX and I get the same OTAs as the non carrier version. Is that correct or can the last bit not be changed and I am stuck with delayed updates?
[Samsung Galaxy S22 Ultra] gpap2004:
You can receive OTA updates when there will be a new SEK firmware for update. Google Pay works well. Samsung Pay not supported with SEK firmware (neither EUX )
[Samsung Galaxy S22 Ultra] gpap2004:
It is correct
[Samsung Galaxy S22 Ultra] ratchetrizzo:
This works pretty well on the S22U, it has static at the beginning of the call though and i WISH it wouldn't automatically record every call but let you hit the button after the call starts. (I dont care for the box that pops up before it lets the call go through asking if you want to record the call or not.) Maybe it has to ask before putting the call through to have it work properly but the couple tests calls I made all sounded pretty good with some static. I dunno if it's worth $9.99 though since who knows what will appear since this phone is brand new
[Samsung Galaxy S22 Ultra] Diac799:
Now I don't know what going on , customer service on chat guy say all models all is supported to change csc 🙄 so then why I can't change to SEK

So when I click read info ADB all is OK when I write SEK in small window t chose csc show me error can't read IMEI lol maybe I do something wrong , this soft is not supported, and samkey say is supported
[Samsung Galaxy S22 Ultra] gpap2004:
From my experience, samkey doesn't support all firmware. For the s22 ultra the initial A7 Exynos firmware supported as I already done the procedure. The late B3 or BF may not supported and need to downgrade first in A7 through odin
[Samsung Galaxy S22 Ultra] charoyomisma:
I updated to the new software and samkey tells me that the imei is not accepted
[Samsung Galaxy S22 Ultra] gpap2004:
As I already wrote above , the new firmware for Exynos currently not supported from Samkey. Only the previous one (...A7)
[Samsung Galaxy S22 Ultra] Diac799:
Customer service Samkey say update for s908B coming soon 🙂
[Samsung Galaxy S22 Ultra] ilpincio85:

[Samsung Galaxy S22 Ultra] gpap2004:
For now only EUX csc has got latest March update. We will wait for SEK when the time arrived. Be patient. SEK doesn't takes firmware first but a few days or week later
[Samsung Galaxy S22 Ultra] eddiedimitris:
can anyone please with Sek csc tell me if has take any upgrade after January ?It is stuck there I think
[Samsung Galaxy S22 Ultra] tomesiek:
Hi,

I'm on SEC CSC and never get any update.

I you want you can download EUX firmware and use HOME_CSC to keep SEC in your phone. I did that yesterday. Now got March security patch.

For next update will wait trough OTA update.
[Samsung Galaxy S22 Ultra] eddiedimitris:
Do you think that there is possibility not to take ota update for Sek?
[Samsung Galaxy S22 Ultra] tomesiek:
To early to tell. Still no official firmware for SEK witch march patch.
[Samsung Galaxy S22 Ultra] gpap2004:
I'm pretty sure that there will be a SEK firmware update , maybe in late March. I took a look to SEK firmwares for S21 and S20 and I saw that all the phones updated to latest SEK normally. But as I said before, it can take some time to see the OTA update. First , we see EUX or DBT (Germany) and then all the others. Otherwise, you can download latest EUX and pass csc-home through Odin. Personally, I will wait the SEK OTA update.
[Samsung Galaxy S22 Ultra] nibera:
Hi, I wanted to ask having an s22 ultra with EUX firmware version AF, can I switch via samkey to the CSC SEK? or I must first downgrade to version A7 via ODIN then change the CSC SEK with samkey and then via ODIN always install the EUX A7 firmware by putting the following files in ODIN:

AP_S908BXXU1AVBF_S908BXXU1AVBF_MCL23767760_MQB49504099_REV01_user_low_ship_MULTI_CERT_meta_OS12.tar.md5

BL_S908BXXU1AVBF_S908BXXU1AVBF_MCL23767760_MQB49504099_REV01_user_low_ship_MULTI_CERT.tar.md5

CP_S908BXXU1AVBF_CP21734578_MCL23767760_MQB49504099_REV01_user_low_ship_MULTI_CERT.tar.md5

HOME_CSC_OXM_S908BOXM1AVBF_MCL23767760_MQB49504099_REV01_user_low_ship_MULTI_CERT.tar.md5

by doing so I will have the EUX firmware updated to version A7 with the CSC SEK, right? so I don't lose the phone call registration form, right?
[Samsung Galaxy S22 Ultra] gpap2004:
If Samkey supports your EUX AF CSC, yes you can get the SEK. I don't know it , as I did it with EUX A7 CSC via Samkey.

Give it a try and you see. It won't let your phone damaged, don't be afraid.

No Odin can help to change CSC
[Samsung Galaxy S22 Ultra] charoyomisma:

[Samsung Galaxy S22 Ultra] gpap2004:
You flashed through Odin the EUX home-csc only , right?
[Samsung Galaxy S22 Ultra] ragnarok555:
Hi. Do you mean I can get recording calls by using the old method with Sammobile simply changing the firmware to Ucraine or do I need to go to the method with SamsKeys? Thanks a lot
[Samsung Galaxy S22 Ultra] SgAndrea:
So if I understand correctly, I put the eux firmware and the csc SEK?

I add, what are the differences between these 4 firmware?

EUY,EUX,BTE (uk),BTB(uk)?
[Samsung Galaxy S22 Ultra] gpap2004:
No. IF you have SEK via Samkey, you can flash EUX firmware putting all the files and in CSC you put the Home-Csc of EUX. But first you need to have SEK via Samkey
[Samsung Galaxy S22 Ultra] gpap2004:
Look , you have need to have SEK via Samkey, then you can flash EUX firmware putting all the files and in CSC you put the Home-Csc of EUX. But first you need to have SEK via Samkey. Otherwise, wait for OTA SEK update in a few days
[Samsung Galaxy S22 Ultra] SgAndrea:
Thanks! Can you tell me exactly what's wrong? Samsung pay? Which I don't use. then ?
[Samsung Galaxy S22 Ultra] gpap2004:
As I already wrote about that in a few earlier posts in this thread, SEK is amazing , if you get a reset you won't lose SEK and you will have a totally clean phone , without any bloatware. No Facebook, no Netflix , no Microsoft, you can download all separately if you want.

Google Pay is working.

There is no Samsung Pay for SEK.

If you have a Samsung watch 3 or 4 from EUR you can't use Samsung health monitor app for HCG and Blood pressure. All other watch functions are working well .

Hiya isn't present for spam blocking, you can download it from Play store for free
[Samsung Galaxy S22 Ultra] SgAndrea:
So the best solution is: buy credit from ebay, change csc in SRK with samkey, put EUX firmware with odin. I forgot something? As a watch I have a garmin, so I shouldn't have any problems right? TNX
[Samsung Galaxy S22 Ultra] gpap2004:
Right. But you mean SEK , not SRK , ok ?😀 You don't need to flash EUX with ODIN, because SEK firmware can take updates normally via OTA , little later than EUX , but it's ok. If you are inpatient, you can flash EUX via Odin. But it is not necessary...

The next step is Samkey be compatible with your current EUX firmware... Samkey doesn't support later EUX firmware. I have done the CSC change in my EUX phone when I had the fisrt firmware, A7. Now , with the latest March firmware I don't know if Samkey is compatible. Officially, Samkey is not support the s22 phone in its page. You can try and if the process stopped means that you can wait for Samkey update or downgrade to A7 SEK or EUX firmware..

Hope I helped 😃
[Samsung Galaxy S22 Ultra] SgAndrea:
yes i understand, but i would like to have call recording but immediate updates. So I can put the csc SEK, and putting the eux with odin I will have the registration enabled but the super updated firmware right?
[Samsung Galaxy S22 Ultra] treoking:
Hi!

I'm trying to change my ATL (Vodafone) CSC to the EUX basic CSC, because I want to receive the OTAs without waiting for the carrier.

I have the AVA7 firmware from Vodafone and tried to change in SAMKEY to "EUX", but the operation was not succesful. SAMKEY do the job, but the CSC is not changed. When the phone restart, the software was EUX/-/EUX/ATL.

¿I need to flash AVA7 firmware EUX previously? What CSC do I need indicate in SAMKEY?

Thank you!!
[Samsung Galaxy S22 Ultra] charoyomisma:
samkey is already compatible with the new eux firmware, i have tested it
[Samsung Galaxy S22 Ultra] nibera:
hello, so you can already start with the new EUX firmware with AF final for the change of CSC SEK, right? where can i find samkey credit pack purchases of 4 or 5 credits?
[Samsung Galaxy S22 Ultra] SgAndrea:
HOW MANY CREDITS does it take?
[Samsung Galaxy S22 Ultra] nibera:
I wanted to try, no more than 5
[Samsung Galaxy S22 Ultra] ilpincio85:
you need 1 credit in order to change CSC

At the moment i'm downloading AVBF with SEK CSC see attachment
[Samsung Galaxy S22 Ultra] nibera:
I know, if you want to go back then you need more credit, and so on.
[Samsung Galaxy S22 Ultra] SgAndrea:
perfect therefore, 1 credit to change the csc in sek and then I put the eux as firmware. optimal

Not with SEK. Only as a third party app
[Samsung Galaxy S22 Ultra] eddiedimitris:

Any help would be appreciated.
[Samsung Galaxy S22 Ultra] tomesiek:
With this version is no problem to change CSC with SamKey.

If this is a Snapdragon version you can use THL csc. You not flashing anything, just connect your phone, develop options and debugging on, type needed csc in SamKey and klick change csc. You will need one credit for that.
[Samsung Galaxy S22 Ultra] DeaDman594:
Thank You so much for the help i will try to do it. but I purchased credit from ebay they didn't email me anything. Are they suppose to mail me?

Answering my own question, THL seems to be very consistent on updates.

Just a few questions before flashing OXM on my S90*E using Odin:

1) Samkey is working on AVBF or it is safer to flash AVA7? Just to make sure changing csc is gonna work

2) Google Pay is working on THL?

These are good news but maybe there is a catch: as INS csc is for 908E (snapdragon) , although you did it changing csc for 908B, you may not getting OTA updates anymore. Please inform us when the next update is available.
