In Greece, coamote supports volte but it won't work on my device. I have it enabled from the settings and from the carrier (each person needs to activate it by sending a sms code to the carrier).

Do I need to flash a Greek firmware?

Edit: I tried to DE activate the service (I activated it while I had a non volte phone) and re activated it and it works now.

Hi all, still no news to pass on CSC Xef ?

I search a lot but I can not find anything. Yet I had found a procedure a few years ago with a member of XDA, unzipped the firmware, change the master csc by the desired one and have it compiled again. Nobody with this knowledge on xda or here managed to do it this way ?

I also know that my method is tedious !!!

I asked Samsung who did not even know what a csc was!
[Samsung Galaxy S10 Guides, News, & Discussion] dovedescent7:
So confused. Op didnt say whether this Snapdragon or Exynos.

I have the G970U on the way and am so confused about what i can or cannot do as far as changing csc

and also confused if the snapdragon can even be rooted.

Just posts everywhere with not much context.
[Samsung Galaxy S10 Guides, News, & Discussion] Luke301:
So it's possible!

I'm trying to do the same thing with the ITV csc.

Can't find that procedure anywhere on the Internet though..
[Samsung Galaxy S10 Guides, News, & Discussion] sins07:
the guys at Samkey have added support for this feature to change Single-CSC codes. it doesn't require root and it's cheap.
[Samsung Galaxy S10 Guides, News, & Discussion] Ryan1469:
Really? Have you tried it or anyone here who has done it as i am overseas atm and away from my pc so can't even check it out.
[Samsung Galaxy S10 Guides, News, & Discussion] argenter:
Hi! I tried and works. Downloaded samkey codereader 2.15 from samkey.org, bought 15 credit, 2 needed for csc change. No f.reset, no knox trip, it works just fine within OXM multi-csc. Read all help section!!!

[Samsung Galaxy S10 Guides, News, & Discussion] argenter:
Yes, G973F (Exynos) Dual SIM.

What this mean all I have BTU with EE SIM. If I put second sim from different region will it change?
[Samsung Galaxy S10 Guides, News, & Discussion] orlandson:
You got all 4 CSC codes changed? Did the same, but my last CSC remains unchanged. Now I have ZTO,ZTO,ZTO,UPO.
[Samsung Galaxy S10 Guides, News, & Discussion] argenter:
Last one always remains unchanged, but no problem because that is not the active csc, it just a product sales code, an info, do not worry about it.
[Samsung Galaxy S10 Guides, News, & Discussion] Luke301:
Perfect!

But do OTA updates still work after the change? :confused:

Also could you link me the help section of the tool, I can't find it anywhere, even in the official forum!
[Samsung Galaxy S10 Guides, News, & Discussion] orlandson:
Yes, you will have OTA updates.

You can find the help section inside Samkey software.
[Samsung Galaxy S10 Guides, News, & Discussion] Rexton270:
FYI you have S10+. BTU is unbranded. Why and for what you want to change?
[Samsung Galaxy S10 Guides, News, & Discussion] Nettwerk:
I don't want to change but I asked what does it mean? And it will not change if I put sim2 different country sim or just different operator sim.

[Samsung Galaxy S10 Guides, News, & Discussion] sins07:
this won't work as flashing combination is not allowed through public methods. Single-CSC codes in the OXM group can benefit greatly from Samkey's CSC changer.

---------- Post added at 05:13 PM ---------- Previous post was at 05:03 PM ----------

Samkey is not a shady site, it's been part of the unlock industry for years and has an established community around it. look at their forum.
[Samsung Galaxy S10 Guides, News, & Discussion] Luke301:
Last question: does the phone reset after changing the CSC with this procedure?

Thanks
[Samsung Galaxy S10 Guides, News, & Discussion] orlandson:
No. All my data remains intact after CSC change with Samkey. Did an OTA update minutes after, already with the new CSC code. Some apps will change language, as Samsung Members. Everything is working fine, including Samsung Pay (installed from Play Store).

I'm only thinking if should flash the whole firmware of new CSC with Odin.
[Samsung Galaxy S10 Guides, News, & Discussion] Luke301:
So, after changing the CSC, if you reset the phone via recovery the CSC will be the same or it will revert back at the original state?
[Samsung Galaxy S10 Guides, News, & Discussion] orlandson:
I don't know, but can't see why It will revert back after reset. The new CSC really became the default CSC (you can check it with app Phone Info).
[Samsung Galaxy S10 Guides, News, & Discussion] Luke301:
Ok, I'll try.

Thank you

If u remove your sim card before hard reset, your csc remains intact, if make hard reset with sim card inserted with another region will revert.

You can't.
[Samsung Galaxy S10 Guides, News, & Discussion] Luke301:
Changed CSC with the SamKey Tool, resetted with Sim Card in, csc didn't revert.

All good!
[Samsung Galaxy S10 Guides, News, & Discussion] kris.sg:
I did it too.

But one thing if you change csc, your phone must have firmware

That supports csc

(New one that you set)

Cheers

Kris

P.s. i do it samkey sorry for mistake
[Samsung Galaxy S10 Guides, News, & Discussion] Luke301:
But if you flash via odin the firmware with the CSC file (not HOME_CSC), you must do the procedure again or the default CSC will be the same you set with the SamKey tool?

Wow! It was so easy. Just changed from BTU to XEO in 5 minutes with SamKey.

All I had to do was:

- buy 2 credits from ebay (around $5)

- download samkey

- enter the login details

- disable fingerprints or lock pattern (disable lockscreen completely)

- make sure that you have right connection with the phone by Read Info ADB

- write your desired CSC on the field and click Change CSC

- phone will reboot two times itself and operation will be completed!

My data and configuration were not tocuhed at all! All good

OMG it really worked, soo I bought 2 from eBay but didn’t get them right away so I bought 15 directly form Samkey. I tried to cancel the eBay ones, but if I can’t, I’m willing to sell them really cheap if someone wants them, also I have 13 remaining directly form Samkey is there any way I could divide them so I can give them for free 2 by 2? I’m willing to help the community it’s been 5 months of frustration for me so if I can help I’ll do it

Ps. If I do a factory reset will the csc will stay?
[Samsung Galaxy S10 Guides, News, & Discussion] jabreel.torrin:
After some help and tips from Luke301 and Orlandson I also was able to make it work.

1. Buy 3 credits (can't buy 2) form this seller that Luke301 recommended to me for 6,60 usd total: animeman65

(2. If you don't know how to flash official samsung firmware (which will not trigger KNOX), check: XDA: How to update the firmware on any Samsung phone)

3. Flash official samsung OXM firmware I downloaded with Frija (not sure if necessary but in the Samkey application it says you need to do this first). You can also use sammobile but downloading takes very long (6 hours).

4. Enable developer options on your phone: Settings > About phone > Software Information > Tap "build number" 8 times or until you see a pop-up message that says "Developer mode has been enabled".

5. Turn on usb debugging on your phone: Settings > Developer options > USB debugging > Allow USB Debugging > Tap "OK"

6. Install and open the Samkey application on your computer > Connect your phone to your computer with a usb cable > Login witch the credentials you received from the ebay seller.

7. Insert the CNC code you want into the "Change CSC (Buyer)" field > Click the "Change CSC" button > Confirm that you want to spend 2 credits.

8. Let the application do it's work after which it will reboot and then you're good to go.

Guys, did you tried to downgrade to the original firmware when the the S10 released, i believe this something to do with the latest update, try to downgrade to an older rom via odin and then try to change the CSC using the combination code *#272*imei# , i did not test it as i have a note 10 plus, Let me know if this work for you,

Guys, so if I understand this correctly, using Samkey...

Can I change the CSC from BTU to PHE in my S10 G973F or do I need to flash OXM one first?

And I won't trip knox? No need to reflash?

I want to do it because I don't have Samsung Rewards using BTU (UK) in Spain.

This better work for my SM-N9750. I'm about to reset it for the 4th or 5th time in a week in my quest to change the CSC from BRI to TGY :eek:
[Samsung Galaxy S10 Guides, News, & Discussion] waqqas.khokhar:
Well, I'm glad (and super-relieved) to report that it worked! The only FYI is that the first attempt (after SamKEY rebooted my phone) actually timed out. But without doing anything else, I just hit the "Change CSC" button in the app again and it went through.

The CSC was changed and the desired effects were there: "Places" appeared in the Phone app and I was able to enable the Smart Call options in Phone Settings.
[Samsung Galaxy S10 Guides, News, & Discussion] meowone:
It also gave me a new option to use mobile data on the 2nd Sim Card while the call is on the 2nd Sim. This is better than I thought.

so samkey works on an Galaxy s10 SM-G973f?the phone is listed on 6 credits and i wonder if i can change my csc with this from PAK to PHE?as i have try so many restores using different firmwares and so far nothing is changing it
[Samsung Galaxy S10 Guides, News, & Discussion] orlandson:
Just read previous posts.
[Samsung Galaxy S10 Guides, News, & Discussion] coccco28:
well cheers for the tip didn't go two pages back to check ahahaha.well then will restore and try it see how it goes.
[Samsung Galaxy S10 Guides, News, & Discussion] coccco28:
well for my surprise all worked well.now do you know if i flash the PHE firmware the csc will change back from PHE to PAk?
[Samsung Galaxy S10 Guides, News, & Discussion] Eluryh:
Reading the previous posts, I still have a doubt.

I flashed the PHE firmware using the CSC and, on my S10, it remains as BTU. This is a known problem in spanish community.

My question is: do I have to flash or delete all my data again in order to use Samkey and try to change BTU to PHE? Or should work just enabling ADB in settings?
[Samsung Galaxy S10 Guides, News, & Discussion] coccco28:
samkey will ask you to use the csc and not home csc so when you flashed your phone if you used home csc to preserve your data then yes you will need to flash it again and use the csc and not home csc as i mention on the message
[Samsung Galaxy S10 Guides, News, & Discussion] Eluryh:
When I flashed one month ago, I used the CSC, not the CSC HOME, because there was no data on the phone when I bought it and I flashed the PHE firmware (that remains as BTU) on day one. But now I have all my stuff and data there. Do I have to flash again and delete my data?
[Samsung Galaxy S10 Guides, News, & Discussion] coccco28:
then no.as long as you used the csc and not home csc all should be just fine but make sure to connect your phoen to PC first and have the usb debug on give all the permissions and thats it.i also after change the csc as now i have PHE/PHE/PHE/PAK i flash again my phone with the PHE using the csc to erase everything and for my surprise the csc didn't change back to PAK/PAK/PAK/PAK so all great and now i have samsung pay too
[Samsung Galaxy S10 Guides, News, & Discussion] Eluryh:
That's amazing. So 5 minutes if all is good.

You needed 6 credits for a G973F right?
[Samsung Galaxy S10 Guides, News, & Discussion] coccco28:
well is 2 credits from what i see not sure for what was or what i see on the page 6 credits but toke me 2 credits only well i paid 4 in the end because i didn't set well the permissions between the phone and PC

My phone is on July patch, because my network operator release very slow updates
[Samsung Galaxy S10 Guides, News, & Discussion] orlandson:
What's your actual CSC?
[Samsung Galaxy S10 Guides, News, & Discussion] andQlimax:
TIM (screen attached).

What I want is having the latest firmwares on time via ota, and not having to wait 2 months delay due to my operator
[Samsung Galaxy S10 Guides, News, & Discussion] orlandson:
Just after you change CSC to ITV you will start to receive OTA from ITV, once ITV have TIM as "available CSC".
[Samsung Galaxy S10 Guides, News, & Discussion] andQlimax:
That's cool, so no manual flash required.

I guess I will have to manual flash the branded firmware only in case I wants to revert CSC from ITV (unbranded) to TIM, in case I need to send my phone for assistance
