if you flash non Indian roms , you will lose native VOLTE calling function.
I wouldn't mind using it, I have the Wi-Fi version so what an effect me. But it probably won't work I have the SM-T830.
Any screenshots?
can i use it with SM-T830 model (WIFI only) ?

Will I still get OTA updates in the future if I flash this region's firmware and will I lose any data
hey all- any reports on whether something like Swift Installer will work on Pie? it does on my Pie on Note 9 but i know it doesn't on the S10.

Probably not, this should be a multi CSC ROM, so unless he change his CSC manually, he will stay on INS (India) CSC

Indian CSC (INU or INS) is not available in the French firmware. So when we flash CSC, it'll change the default CSC to French. This hap to me when I flashed French Oreo rom on my tab. I had to revert back to Indian rom to get the VOLTE call feature back.
Please excuse me if I'm wrong.

I am not sure if the French ROM is multi CSC, if it is, it should include the INS CSC, I flashed my Note 9 with Indian firmware but it was multi CSC, and my phone still have the MID CSC not changed
I didn't have the time to flash my tab yet, I'll do it soon and report if my CSC changed
Flashed my tab, CSC have been changed to XEF but I am using it without a Sim card, I used the home CSC so my data stayed intact without wipe (for testing because I factory reset it manually to avoid bugs)
If you've upgrade can someone see if you are able to downgrade back to Oreo? I am happy with the Oreo rom and hate when they make it so you can flash a lower build incase the new one is not up to par. Its odd that the French version is up before the Korean international version.

Hello,
I try to change my CSC to be able to activate the eSIM and Samnsung Pay,but i'm unable to do that in sdb (it says launch_app csc-manager.csc-pre-configuration that is successful but on my watch it doesn't show the CSC menu).
Is downgrading my only solution and if so , where can i find the firmware because I can't seem to find anything on SamMobile?
Thank you

Phones have USB cable for Emergency Flashing.
Samsung Watches is bigger problem if you kill the """WiFi Security chain"""...
You have not USB cable for easy second attempt.
And the LTE Watches makes more trouble... if you doing something wrong or simple out of luck.

Hi, I have SM-R805F bought in Czech rep. Can I use these instructions for downgrade my firmware to change my region (I want Samsung Pay)? I have saved my eSIM in my watches now - after flashning it will stay there or will be deleted? Thanks a lot
@ohajo3
Yes you can. Do not reset networks after flash during setup. Esim will stay.
I changed my CSC to Australia to get the Samsung Pay but this disabled VoLTE on my watch. I m now not able to call or receive any calls. I m from India. Watch was originally purchased in Australia.
During this process I was prompted for update which I did and now I m stuck with 4.0.0.7 version and no way to change the CSC back to INU using shell access way.
Only way now looks to use the combination firmware and Odin. But not sure where to find the Combination Firmware for SM-R805F LTE version.
Anyone or @adfree can point me to right direction to get the right required binaries ?
My device details
AP : R805FXXU1FSL4
CP: R805FXXU1FSL4
CSC: R805FOXX1FSL4
LTE version.
Can anyone help with the right binary I should use to downgrade?
These are my device details:
AP : R805FXXU1FSL4
CP: R805FXXU1FSL4
CSC: R805FOXX1FSL4
LTE version.
Not able to find combination firmware for this version. Not very sure which one I should use.
Thanks in advance.
@madono
You wish to have India INU?
http://fota-cloud-dn.ospserver.net/firmware/INU/SM-R805F/version.test.xml
IMHO seems INU require OXX package...
Here are 2 OXX packages:
https://forum.xda-developers.com/showpost.php?p=79644543&postcount=1
According to DBT list... they are before Tizen 4.0.0.7
So please try these 2 firmwares... with the old method to change CSC...
So IMHO no Combination Firmware required...
Only downgrade...
Best Regards
Edit 1.
Sorry, my fault...
Links expired.
Edit 2.
Oh, totally forgotten...
Latest FTC1 for OXX region is here:
https://forum.xda-developers.com/showpost.php?p=82893207&postcount=55
INU inside this OXX region.
@adfree Thanks for the links! I m downloading it right now. Speed is slow, not sure if I will be able to download it in one go. Is there any expiry for this download link? If I m not able to download today, will try tomorrow again.
Another question for downgrade, do I have to choose all four files , namely, BL, AP, CP, CSC to downgrade?
I have not done a galaxy watch downgrade before so wanted to be sure not to mess it.
I actually wanted to have Samsung Pay and LTE enabled. It was working fine using Australia CSC code but my Phone operator recently changed calling only on VoLTE. So i was not able to receive calls or call anyone. Only internet was working using AU CSC.
Now it seems I have to choose between calling and Samsung Pay. SP is not officially launched on Galaxy Watch in India. Only on smartphone it is allowed. Not sure why.
Thank you once again!
Regards,
madono
Hi @adfree,
I downloaded the firmware from the link. Today was bit hard day at work so not trying to update watch.
Will try it out with fresh mind tomorrow. Just need couple of things cleared before I try it.
1. In firmware download steps, it is mentioned to only use BL, AP, CSC file?
Downloaded rar has 4 files. Is this fine?
And final one this is my current watch status
AP : R805FXXU1FSL4
CP: R805FXXU1FSL4
CSC: R805FOXX1FSL4
Watch is LTE model.
I m good to go ahead with said firmware?
@adfree please review, don't want to mess this one. I know there is always risk but want to use correct firmware.
Thanks for the help!

Then SDB command to change CSC from AU to India
Thanks to @adfree
One thing I observed that my eSIM was not reset. I was expecting it will be removed when I downgrade. Looks like it is left alone in this process.
Not sure if there is any way to enable Samsung Pay without changing CSC. Missing SP very much in current time.

Did I correct understand:
To change CSC by old method (with SDB) it is needed:
1. Flash with Odin all 4 files (early Firmware)
2. Change CSC with SDB
3. Install Samsung Pay
4. Flash with Odin all 4 files (latest firmware) back to FSL4
and Samsung Pay will stay?
I've tried looking for a bit now and I can't seem to find this anywhere. Looking for the SM-R820 (Galaxy Watch Active2 - WiFi/Bluetooth - US). Can someone point me in the right direction?

Hi guys,
I want to change my GWA2 40mm LTE (Unlocked) US (R835U) Tizen 5.5.0.1 CSC to something working in Canada. In the first step, I need the firmware files. I appreciate it if someone could share them with me and other users. An expert member told me that I need the following files:

or
COMBINATION-FT55_R835USQU1ATJ1 (https://easy-firmware.com/index.php?a=downloads&b=file&id=308035)

Hi Everyone,
I'm from Australia and recently bought a SM-G781B off eBay...
Turns out it was a UAE variant and Samsung Pay is all messed up.
I've flashed the phone a few times now using ODIN, trying to get the right CSC correct for Australia (G781BXXU2CUB5) for either of the following CSC's;
XSA (Generic Australia), OPS (Optus), VAU (Vodafone), or TEL (Telstra).
The issue I have is all the Stock Firmware's I've download and flashed keeps registering my CSC as XME (Malaysia)...
Phone INFO app doesn't even detect any other CSC's in the package
I've tried downloading the correct Firmware packs from the following and none gives me the correct CSC for Australia;
https://samfrew.com/
https://www.sammobile.com/
https://samfw.com/
App: Frija Firmware
Does anyone know why this is happening, or can upload/direct me to correct firmware either XSA, OPS (Optus), VAU (Vodafone), or TEL (Telstra)?
I'm totally at a loss now...
Any help would be much appreciated, thanks heaps in advance.
from what I've read recently Samsung has stopped people being able to switch as of android 11.
maybe... I stress MAYBE according to your countryman Hugh Jefferys, if there's a lower version of firmware on the same binary number you might be able to downgrade and then that might mean you can switch CSC.
this is someone who's never even tried changing CSC telling you this so your own research is obviously the only thing to put some faith in.
good luck
XSG (UAE) firmware is part of the OJM multi CSC, whereas XSA/OPS/TEL are part of the OLM multi CSC. This means that it is not possible to simply flash XSA in Odin as the multi CSCs are different, you would first have to use the combination ROM to change from OJM to OLM and then you would be able to flash any OLM CSC firmware, whether that be Australia, Singapore, Malaysia, or Thailand. I'm an Aussie myself, I got my phone from JB Hi Fi but switched it to Thailand CSC since XSA updates are horrendously slow (Samsung Pay does still work on Thailand CSC as does VoLTE/VoWiFi). For your case though, I'm afraid you are out of luck in terms of changing the multi CSC with the combination ROM, if you are on One UI 3.1 then the bootloader version is U2 whereas the combination ROM bootloader version is U1, so you would not be able to flash it anyway. Also, I tried to flash the combination ROM while my bootloader was still on U1 because I wanted to change from OLM to OXM (Romania CSC) for fastest updates, but Odin was not allowing the flash first because of "please get the approval to flash factory images (pit)" which I fixed, then "please get the approval to flash factory images (abl)" at which point I gave up. So as I said before, sorry but I don't think there's a lot you can do Unless a U2 bootloader version combination ROM is leaked which may or may not happen and you can get around the Odin not allowing you to flash it issues, the phone will unfortunately be stuck on UAE firmware (unless there are other countries part of OJM which you could switch to for faster updates).
Hopefully this helps you.
I have the same model! I changed my CSC but for some reason chat features in messaging app doesn't work now..other than that, all's good..

Your software version is was originally XSA, so you wouldn’t have any issues flashing it with XSA and defaulting to XSA instead of another region. The CSC will automatically default back to XSA.
Mine unfortunately defaults to Malaysia XME when flashed with XSA firmware.

XSG (UAE) firmware is part of the OJM multi CSC, whereas XSA/OPS/TEL are part of the OLM multi CSC. This means that it is not possible to simply flash XSA in Odin as the multi CSCs are different, you would first have to use the combination ROM to change from OJM to OLM and then you would be able to flash any OLM CSC firmware, whether that be Australia, Singapore, Malaysia, or Thailand. I'm an Aussie myself, I got my phone from JB Hi Fi but switched it to Thailand CSC since XSA updates are horrendously slow (Samsung Pay does still work on Thailand CSC as does VoLTE/VoWiFi).

Thanks for the detailed reply.
From what I’ve tested, I have no issues with flashing from XSG OJM Multi to XSA OLM Multi. You can do this provided the FIrmware security number is the same as your current revision. You can’t however flash to a lower security value. See image attached.
The current firmware security value at the moment is “2” running One UI 3.1, Android 11. We can’t downgrade to any security firmware version “1” types with Android 10. If we could, then you can use multiple methods to manually change the CSC .i.e through Google Dialer or IMEI trick.
All the Firmwares at the moment are still Muti regional, unfortunately there doesn’t seem to be a way to change the CSC manually even though they are Multi regional.
All XSA firmwares I’ve downloaded and flashed will keep defaulting to XME as that’s the default unless my original CSC was XSA to begin with for it to detect.
I think the only option at the moment is to use SAMKEY, unless someone comes with with a new Android 11 method...
The other option is to root the phone and ADB to change the CSC, however this would trigger and break KNOX securities.
I did check Samkeys update log and they state it’s supported now, this method wouldn’t trigger KNOX;
VERSION 3.63.9 (PLANET EARTH'S FIRST)
- Added support for G780F (Galaxy S20 FE) ALL BIT
- Added support for G781B (Galaxy S20 FE 5G) ALL BIT
- Fixed FAIL(16) on Slow PC's
- Fixed FAIL(20) on G780F
They’re actually up to VERSION 3.71.9 now.
Might be worth a try.

I can confirm SamKEY works on One UI 3.1, unfortunately it is paid but it does work. You can get an account for cheap from eBay with 1 credit on it which is all you need to do the CSC change. Using it I was able to change from XSA to THL (with no data wipe at all which really surprised me).

Trust me you wouldn't want XSA firmware anyway, the updates are terribly slow for it for the S20 FE 5G (not sure about 4G), it tends to get security patches a month after they should've came out, for example it got the March security patch in April which is pretty awful imo. I think it's the slowest CSC in general for the G781B, if you're on OLM multi CSC you're much better off switching to THL where the updates are a lot faster.

That's interesting, I didn't think it was possible to change between multi CSCs like this without the combination ROM (how you were able to switch from OJM to OLM). If you try to switch to an OXM multi CSC such as DBT or ROM from OLM multi CSC, what happens? Does it work? I'll be honest I never tried it myself but didn't have the motivation to try it anyway as I heard it wouldn't work.

Hi There,
Yes, im sure it works provided the security firmware version is the same as I mentioned above.
I also changed to BTU to test.
I can't test for you any longer as I've returned the device for a refund. Will go buy an AUS XSA Variant.
Attached are the images of my original and changed firmware for your reference.

That's very interesting, when you get the XSA variant can you try and see if you are able to flash a CSC such as ROM or DBT on the phone successfully using Odin? I would love to know if it was possible for this to work or not, I'm on THL myself after changing from XSA and did not think it was possible to switch to a different multi CSC (from OLM to OXM).

Wish I tried it before returning the device. The Australian stock only has 6GB RAM and no dual-sim....

Yeah that's true no 8GB variant sold here as far as I know not even on the Samsung website and we don't even get eSIM support either
Is there an update/workaround on this issue?
are there any methods that work without samKey?
Noticed that the dialer app that was once able to record calls, is now recording only me talking, since the latest OTA updates on the stock firmware (updated to oneUI 3.1 and Android 11).
I'm also on XSG (OJM) firmware and want to change CSC to enable call recording on galaxy S20 FE 5G (model G781B).
Would love to know how can it be done.

thanks!

I'm sure by now you've already sorted this, but this is for future people with a need to change CSC
The SamFW FRP Tool can tell you which CSCs are available on your phone already, and can automatically have the CarrierPreConfig service trigger a CSC update. Only need to enable USB Debugging. No root, no reinstall.
But if your phone doesn't have the CSC you need already, download Frija, or another firmware download tool, you'll be able to download and install an OXM Multi CSC firmware (such as XSA, OPS, TEL or VAU), and install it via ODIN tool.
Be sure to select HOME_CSC to keep your data, and backup first.

Thank you, mate! I have just registered here specifically to thank you You really were the last random post I found in the internet that helped me to solve this unflashable state of my S9. Thank you again! <O
