Stick with DBT, you will get the same updates as BTU, the onlly difference is the domain language which you cna obviously change .
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Nizam_A:
Thanks. I'll see when the may update rolls around. I've been using DBT or btu software via Odin for a while. It's kinda long tho so I hope it's fixed now. There's no more 3 bloatware. The only place it says 3 or H3G is in that column of service provider. Know why?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] sivuha0101:
The last CSC is always the original CSC that the phone was sold with. You can only change it by roooting the phone, but it doesn't affect the phone in any way, it's more for samsung repair centre etc.

Unfortunately mine is on U2 so I guess I couldn't downgrade it anymore.

Is there another working solution for me?

I'm on a FTM (Orange) firmware and want to switch to an OXM one.

Thanks for your help!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Wendigogo:
Update : I flashed XEF firmware with june security patch with Odin yesterday but no success.

To be more precise, I want to switch from FTM CSC to XEF one. Both are in OXM firmware. Firmwares seems to be exactly the same (build date and changelist) but I can't move on. :(

Maybe it's due to e-sim?

Thanks for your help.

i am on android 11 and the last update for july 2020. is it possible to make it csc branding free? any help are welcome
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] teketake:
Hi there.

Which CSCs are capable of grabbing and communicating with 5G signals in countries other than the country where the SM-N986B/DS (Exynos) is sold?

The SM-N986B/DS (Exynos) cannot change settings related to 5G from Service Mode, so it cannot unlock 5G region lock like the SM-N9860 (Snapdragon).

I want to use SM-N986B/DS (Exynos) in Japan, but the UK and Singapore versions reportedly did not grab 5G from Japanese carriers.

I've seen reports in other threads that rooting your device will allow you to configure 5G settings from service mode.

However, I don't want to root my device if I can help it.

It seems that different countries (CSC) have different settings to 5G, so if you know of CSC that can grab 5G in other countries, please let me know.

Thanks for reading.

please anyone help me to change CSC of latest updated Note 20 Ultra
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jfrm:
Hi all, I'm trying to understand all the threads regarding CSC change because I need PHE to use Samsung Pay in Spain, but do not manage to finally figure if it is possible or not with SamKey.

My rom (android 12) is:

Operator software SAOMC SM-N986B_OXM XEH 12 0004 XEH/XEH,XEH/EUX/XEH

Version N986BXXU3EVA9 / N986BOXM3EVA9 / N986BXXU3EVA9

Security Patch February 2022

I understand that while it is a multy CSC Rom, PHE is not included and that Bootloader is 3, so no way to go back to Android 10 and use the phone app trick...

Will Samkey work for me without installing first a PHE rom?

Will appreciate any help.

Thanks

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ChoSmile:

Hello

Can you pls. guide as to how can we change the firmware version from N986B/DS to that of somewhere I can get in built call recorder?

Pls.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ChoSmile:
Using app in Windows: SamFw (free) or SamKey (paid) - to chaage CSC to XXV, THL or INS.

Hint: do youtube search
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] techie_vintage:
Thanks for the help

I searched in Samfw. I am getting the latest firmware for INS which is of Android 13

Now I just need to flash this firmware through ODIN. Correct?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ChoSmile:
No, no need to flash anything, if current CSC and the new desired CSC are from same MultiCSC - just open SamFw and change CSC. Apps and data are not affected just features allowed in for this CSC configuration are shown or hidden.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
You may use any of the links posted on the first page. Yes, INS if you want call recording. I know a few who lost VoLTE and WiFi calling when they switched to INS. It may vary, depending on your country of residence/service provider.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
You mean you were able to downgrade your firmware via Odin without issues? If that's the case then that's good news indeed!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Ing.King:
Means Sep -> Aug -> Jul or Sep -> Jul directly ?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
Flashing with Odin and the official firmware is almost trouble-free. As long as your phone is part of the OXM firmware you should be good. Using the original cable and a perfectly working PC is always advised.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ikeieva:
If yours is part of multi-csc download this https://samfrew.com/tl/download/Galaxy__Note20__Ultra__/mugv/XTC/N985FXXU1ATGI/N985FOXM1ATGI/ and then change your csc code with csc changer apk

The free download will take hours. If you pay a small fee it will download much quicker
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] arsenalove:
Correct but point to be noted after successful flash via Odin (I choose Home CSC using google drive link firmware) , data will be corrupted and recovery will show option to factory reset. I knew well in advance these things can cause data loss. So backed up all necessary info first and did factory reset. Everything is working as expected. I needed the TEL CSC for RCS to work in Samsung messages. Many thanks

---------- Post added at 06:58 AM ---------- Previous post was at 06:56 AM ----------

From Sep to JUL direct with data loss. Thanks
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
Thanks for confirming. True that, all DATA will be lost. I should add that to the CAVEAT! Thanks!

Where is Samsung Pay available?

It's currently available in 27 countries around the world (deep breath): the US, UK, Australia, Belarus, Brazil, Canada, China, France, Hong Kong, India, Indonesia, Italy, Kazakhstan, Malaysia, Mexico, Puerto Rico, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, United Arab Emirates and Vietnam.

Do you live in any of these countries?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] arsenalove:

¿This tutorial works to change my N986B/DS from Vodafone (ATL) CSC to Spain (PHE) CSC?

¿What ROM do I need to install previously? ¿The XOM file N986BXXU1ATGI will work in my case?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
As long as you have a firmware with 'OXM' in the Service Provider SW version, it will work. Check my attachment for the list of CSC. PHE is there, so you should be good to go.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] treoking:
I was made downgrade and start my phone without SIM or WiFi.

When I try to changeCSC with the app the phone starts Samsung Themes but indicate to me that need an Internet connection and update the app. Is normal? What I did wrong?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
That's normal. You may connect temporarily. After the Store upgrade and the theme is installed, disconnect. Then open your Theme, select the theme. "Try Now" will only appear if you disconnect from the internet. It will not work if it shows "Buy".

Sorry. I'm just trying to remember how I did it. But you should get a similar option.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] treoking:
Many thanks!

The tuto worked for me very well with the help of [MENTION=4994286]BlinkThinks[/MENTION]. Confirmed by me that is possible downgrade from the September Patch (S1) and change the CSC running the step by step.

Now I'm flashing last PHE firmware with CSC to make all wipes.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
You're welcome! I'd highly suggest that you check everything first if the PHE CSC fits your needs. So that you can change your CSC again to something else and don't need to go through the process all over again. :)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] treoking:
Thanks Sir. For me the objective was eliminate the Vodafone software and use the PHE firmware from Samsung in Spain.

All OK, phone configured and working!

Process worked for me from already installed September update. Switched to DBT from german Vodafone.

One last question: is the last step necessary or just an information:• The *#272*IMEI# code works again on my phone on the latest XTC firmware, (see attachment for available CSC codes).

The!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
I'm glad it worked for you! That last step is not necessary. I am just stating that for my phone, which is on GLB / XTC CSC, that code has always worked. Having mistakenly changed my CSC to DBT prior to all these, I lost that option. Hence, this thread.

Cheers! :)

If you can downgrade from your current f/w

Couple of questions before i start

Hey Everyone, does anyone have the working link for change csc app? Every download link on the internet is the same and it is not working. And last question: do you have to update to the latest firmware through Odin in case of successfully changed CSC? Why not to update it OTA through settings? I'm just new here, and I've heard sometimes automatic updates stops working after changing firmware. Will I have to flash through Odin every time update comes out if i change the CSC?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
Here' the LINK for the CSC Changer I compressed it. You need to disable your anti-virus when downloading as it's being tagged as harmful.

Some people prefer OTA I prefer flashing to the latest update upon changing my CSC because it's faster and it fully resets my phone with the new CSC intact. OTA update of course

STILL WORKS and will continue to work.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] marvin6six6:
Also make sure you install it in your drive c: with admin privileges.

[MENTION=4994286]BlinkThinks[/MENTION] mine did accept smart sim in sim1 but requires globe sim in sim1 for it to work. Otherwise it will say unregistered sim. Have you tried in your unit? Thanks
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] GalaxySFUN:
Oh my God that was intense, but looks like I've managed to change the csc, and Samsung pay is working!!! Already added a card, I'll go to the store and by something) thank you so much everyone!!! And thank you to the author of this post) You've made my life so much easier!

The last last question: have everyone tried to update OTA through phone settings after changing csc? Is it possible that this will change my csc back to the original?

P.S. For those who will try this too, the original usb-c cable doesn't work somehow(Odin gets stuck at super.img), had to use usb-c to usb-a cable and plug it in to another port.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
I'm glad you got the features you want. Please don't forget to hit the Thank you button! :)

Yes OTA worked and still works. No, your new CSC will be retained - unless of course, you decided to go through the same process. Enjoy your N20U5G!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
Globe SIM indeed needs to be in SIM1. My Smart SIM was accepted only for a few minutes then the same prompt shows. So my set up is the usual one, Globe in SIM1 and my Smart in SIM2. DATA is working on BOTH SIMs (alternately). At least I get 5G on both SIMs :)

Have you tried getting your eSIM reactivated? (I can't remember if it was you who mentioned who had the eSIM activated). I will try to have my eSIM activated at a Globe Business Center when I have time.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] marvin6six6:
Smart in sim1 data is working, had vowifi & volte but needs globe in sim2 (not sim1 as previously mentioned). If globe is removed in sim1, sim1 is detected as unregistered sim.

I still haven't had the time to go to globe store to request for a new qr code esim.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
Oh wow! It works indeed! My Smart SIM works on SIM1, DATA, VoLTE, VoWiFi, and 5G included! This is a surprise! It's been a while since I used a SIM-locked carrier phone. I thought the carrier SIM card has to be in the SIM1 slot always. I guess as long as a Globe SIM (or eSIM) is active on the phone either SIM slots will accept a non-Globe SIM!

Now I'm happier. Smart has always been my main DATA account and I always put it in SIM1 slots on my previous phones. At least now I get to have my previous setup. Thank you for the heads-up!

After I go to Carrier I only have BTB, BTE, EVR, MEO, SFR, SMP. Rest are all single. Which one should I choose. PLease help Stuck there.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
Which CSC do you need? The ones that show 'single' does not matter even if you have a dual SIM. 'CSC / single' works for both dual or single SIM phones.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] DeaDman594:
Honestly I don't even know which one I need. I am trying to get the Native Call Recording on my Phone.

Thank You for the Help and fast response.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
The INS/single (INDIA) has the native call recording feature.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
I thought they will provide you a QR Code card that you can keep. Perhaps you can take a picture and save for later,

before

you scan. Then just print it out or save somewhere for future use :D Unless of course, it's a one-time, unique QR code that has to be generated each time :confused:

BTW, aside from valid ID's, did Globe ask you any other things? Or you just told them, "I want my number activated on my N20U5G's eSIM."? And they obliged without further ado?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] DeaDman594:
Thank you so much. I have one more question on the video After I click Install the phone restarts. but on the Video it shows little different. After restart I should be good to go or When do I need to click Remove ChangeCSC?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
You can just ignore that as your phone will restart and reset to factory default with your chosen CSC. That step is redundant.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] marvin6six6:
No need for valid id just tell them your postpaid number and account, just had my esim activated yesterday went to globe store. The esim qr code generated is per device meaning you can re-add esim profile on the same phone. Since I changed phone unit from iPhone to Note 20 Ultra, they provided a new qr code. The previous qr code for the iPhone is now invalidated.

Upon esim activation the phone detected an unregistered network on sim1 but continue to provision esim, after restart everything is back to normal.

You don't have to update via ODIN. Matter of fact- I changed my CSC using this method from XSA to TEL and upon restart of my phone and checking OTA Software update. I had the OTA from TEL. No issues at all.Thanks
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] DeaDman594:
Thank you so much. I finally got the Native call recording. And on INS.

I have one last question. If I flash with BTU now via Odin and use Home CSC will I still have the call recording? I already updated to the August Security Patch. Via OTA.

Thank you much appreciated.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
BTU has no call recording. I don't see any reason to flash with BTU as you mentioned you already got the update via OTA. They're from both THE SAME OXM firmware. However if you still want to, just select Home CSC. I read somewhere someone flashed to BTU firmware changed his CSC. Not so sure about that though. You can try it though and keep us posted.

F/DS? Because the firmware posted here is for SM-9

86

B/DS. I can't find your phone's model number at samfrew.com. There are firmware for the SM-N985F/DS though. You should download the JULY firmware.

I just did, but after changing to another CSC (XTC) , not sure if this should have call recording!.

So, you mean there shall some option on call settings to be selected for call recording ?!

BTW: the CSC layout after updating the CSC became like this INS/INS/INS/KSA , the last one is still keeping the original device CSC! ?!

Edit1: I just reinstalled the INS again through the *#272*xxxxx# command and will check it out .... !

Edit2: Yes, I got it in the call settings, Activate "Auto call recording"! - it is working fine!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
XTC does NOT have the built-in call recording. I only know of INS that has one. Of course, that will be the outcome because your phone is meant for KSA since you changed your CSC, (because you wanted native call recording). More info about CSC from this LINK. Kindly read the article for you to get a better idea of CSC.
