Change CSC AUT (EUY) to XEF (EUX) possible? - Samsung Galaxy S20 FE Questions & Answers

Hi everyone,
I recently bought a Galaxy S20 FE 4G (SM-G780G) in Switzerland. As I am living in France, I inserted my french SIM card, but the phone is still displaying AUT / AUT, AUT / EUY / AUT.
The CSC is AUT (included in EUY group), but I would like to change CSC to XEF (included in EUX group).
It is not really clear for me if this is possible (with Samkey) as the two CSC's are not in the same group. The phone should of course still work 100% after the change and warranty should stay valid.
Thanks in advance for your help.

Yeah you can do that.
Android 12 should roll out soon in our region.. I'm from Germany and use Malaysian firmware, when I flashed I did so without selecting any csc in Odin. And it automatically installed the one I needed I think.
But it will factory reset your phone.

I also installed XME to get Android 12 first. I noticed a worse overall performance though. Are Android 12 ROM running significantly cooler than Android 11 since thermal throttling seems to be an issue to every S20 FE user..? Any CSC that might perform better in this area since some CSCs have regional difference like SER from Russia comes without Bixby?

before you pay out money (I've heard that Samkey told one user our device wasn't supported) maybe the method outlined in this thread is worth a try, but using the pit file from XEF
How to change CSC back to original if you are not able to
So i have a S20Fe exynos and me being impatient installed oneui4 SER version on device thinking that will see whatever happens. I am also developer of Clean OS rom for s20fe so i tried using my csc feature script and it worked flawlessly in SER...
forum.xda-developers.com
if it doesn't work fully then the same method should be able to return it to AUT if needed.
curious how it works out if you do try it.

Do you guys know what countries uses EUY and EUX?
I've got a new phone and i like to use AUT ROMs but so far all we have are EUY and EUX, not AUT

hi ,
i can give you an idea what to do .?
Please note ,this was my experience .
Firstly ,i was originally on CSC XFV/XFV/XFV (Vodacom )
I flashed the United Arab Emirates XSG ,when Pie originally came out, for Note 9.
I did a dirty flash and landed on a CSC XEU ( Ireland )
eg . CSC XEU/ .?.. /XFV
When XFE was available , flashed XFE ( i did a clean install /factory reset) with my
XFV service provider/ sim card in .
I landed on XFE/XFE/XFV
Note that CSC ( 3rd one above,) is your "hardcore " CSC..... xxx/xxx/ XFV
( Does not change if you flash )
When XFV came available ,and as i had no Samsung Pay ,no voLTE ,no inbuilt spam protection ,and i also would not get any OTA from my service provider ,i decided to flash back to XFV etc .
I flashed XFV ( sim card in ,factory reset )
I was back on CSC XFV /XFV/XFV
Everything was working fine eg voLTE ,Samsung Pay etc ....
This was my experience .
I have also noted that a XFA device/sim , when flashing , XFE (a unbranded Samsung CSC , South Africa ) ) does sometimes give slightly different results !
Most probably,
due to your Service Provider, CSC restrictions ?
eg ,
where i had no voLTE ,wifi calling ,Samsung Pay etc ,
a XFA device flashing XFE would have these functions .
I would suggest when flashing XFE ,do a clean install/factory reset with your XFA (MTN sim ) . It might help ..????
Good luck
Posr note.
Just remembered reading in your local
(MMb forum, Note 8 forum) yesterday, that a forum member,
flashing another country (Pie) multi CSC (can't remember which) on their XFA device, also
retained XFA/XFA/XFA.
So different results. as mine .
So it seems normal.
Maybe don't stress, it appears normal /right!
Thanks I may try this.

Hi,
I added a edit Post note comment.
Don't know if you read it.
Re local MMb forum Note 8 forum, where a member that flashed another country Pie multi CSC (cannot remember which country) If you want link to his local MMb post, i can post it when i have time. .?
So,
i would now say..... if you flashed XFE re Odin, and you are still on XFA/XFA/XFA
then it's normal... ok.
It does not mean that your Note 9 can't /does not want to flash XFE.
Anyway i also read on local forum that PIE Note 9, XFA is available .!
You could always Odin, reflash Pie XFA ?
Good luck.
Just hate the vidacom rubbish built in to xfa, and don't think all the health sensors work Spo2 and Stress sensors don't work (i think) i was on xfa then flagged the uae csc then after that flagged xfe and am now on xeu xfe with all sensors working but no volte or down protection in calls. So it's a bit of give and take...

Seeing that Note 9 Pie/XFA is out
why don't you just Odin, flash back to XFA ?
When i was on XFE, with Vodacom device/sim , i had no volte, no wifi calling, no Samsung Pay, No inbuilt Hiya spam protection.... and no Vodacom splash screen!
Yes i could see the relevant settings eg wifi
calling .. greyed out.
Samsung Pay .. not working. etc.
When i flashed back to XFV all was working again.
So these features was "restricted/blocked " in my Service Provider sim.
Only plus i got with XFE, was video calling was available on phone dailer.
On XFV video calling is hidden.
You can receive video calls, but not make them.
Good luck

Can you explain me a little bit your process and what do you mean with no volte or down protection in calls?. I will like to have SP02 and sress sensors on rather than some other functions.
Thanks

Changing multi CSC from OLM to OXM using combination ROM?

Hello all,
I have an S20 FE 5G G781B running the THL CSC, December patch One UI 3.0 (changed from XSA which was original). I'm wondering how do I go about changing the multi CSC to one of the OXM CSCs? I have read it can be done using the combination ROM and at the moment this is possible since the bootloader version is still U1, same as the combo ROM. Does anyone know the exact process to go through to change from OLM to OXM? Thanks

I have also two G781Bs, these are PHE and ATL.
OXM from G781BOXM2CUB5 includes these CSCs:
BTB
BTE
EVR
MEO
SFR
single/EUX
single/3IE
single/AMO
single/ATL
single/ATO
single/BOG
single/BTU
single/CNX
single/CPW

single/VOD
single/XEC
single/XEF
single/XEO
single/XEZ
single/EUY
single/AUT
single/BRI
It does not include THL CSC. THL is included only on OLM firmwares (for example G781BXXU1BUA5_G781BOLM1BTL8_THL).
I think none of these OXM CSCs includes call recording
OLM from G781BOLM1BTL8 includes these CSCs:
single/XME
single/THL
single/XSP
single/MM1
single/SIN
single/STH
single/ATS
single/XSA
single/TEL
single/OPS
single/VAU
THL is not included on the OXM firmwares from S20 FE5G, and I don't know what will happen if you change firmware to OXM.... if you change it please, post results here.
And if you can answer me a question please do it: THL has native call recording on S20FE5G?
Thanks in advance.

Question Changing CSC only with Odin?

Hello
If I want to change my CSC (MID) to another one let's say the UAE one, can I simply flash Home CSC in Odin?
If yes should I follow the same step as flashing an entire FW ?
And can I find the Home CSC alone or I have to download the full FW Zip?

HOME_CSC does not change the CSC code, you would use the other CSC firmware file.
However, mixing firmware files from different versions or regions is not advisable.
Sadly and to the best of my knowlege it is no longer possible to change CSC using ODIN & flashing just a stock Samung FW pack.
You need to buy credits and use an online service (Samkey?) to change CSC on Samsung phones now.
I've changed CSC from VOD (uk) to XID (Indonesia, for native call recording) with Odin without wipe anything. I only flashed stock XID firmware with home_csc and it works without Samkey

Xid is not from multi csc, it's single csc.
But how about to change first to to XID and then to the wanted CSC Region ?

Yes it will work I think. I changed with DBT to XID and today I flash DBT back and I have DBT. So I think different countries should change as follows. And I don't have to use samkey
i have downloaded a full firmware for my s20 plus 5g Korean version, and i also downloaded the full firmware of s20 plus from the Philippines. i want to change my csc to Philippines using Odin. should i check all the file inside the s20 plus firmware from the philippines or just the CSC file only? then the rest is from my s20 plus 5g firmware file

Official Rom for Samsung Galaxy S20 FE 5G SM-G781B/DS 128GB 8GB RAM

The Samsung Galaxy S20 FE 5G SM-G781B/DS came with Android 11 and CSC Region Code is INS\INS,INS\INS (India).
When I flase ILO (Israel) Firmware the CSC Region Changed to XSG\XSG,XSG\INS (United Arab Emirates) instead of ILO?
what's going on?
how to get the ILO CSC?
rom archives are multi CSC so what you downloaded for Israel is gonna cover a few countries in the same region. without you having a SIM card from Israel in the phone I'd imagine it's using some other parameters to guess. the frequency bands you're currently using might determine which CSC you get because it's the closest match for example. I'm guessing there but I can't think of another reason right now.
