Change CSC for S20 Note Ultra 5G - Samsung Galaxy Note 20 Ultra Questions & Answers

I am trying to change the CSC on S20 Note Ultra 5g for the following reasons:
I have T-Mobile service but don't currently get 5g. I am told by T-Mobile support I am not getting 5g because the bands used in UAE and US are different. I'd like to get 5g and am hoping changing the CSC after flashing the ROM is one way. I also would like to get automatic recording with the phone dialer. Below are the details and things I've tried. Any help is greatly appreciated as I am lost.
S20 Note Ultra 5G (SM-N986B/DS)
Has UAE CSC (XSG/XSG)
Multi-CSC ROM - N986BXXU3DUH2
Service Provider Software Version - SAOMC_SM-N986B_OXM_XSG_RR_0009 XSG/XSG, XSG/XSG
OS Android 11 with August 2021 update (and July 2021 update)
I've tried the following:
Flashed the ROM with several of them (UK, INS, Germany, Israel etc). Both HOME_CSC & CSC
Rooted the phone (unlocked boot loader)
Tried *#272*IMEI# - this give the Connection Problem or Invalid MMI Code.
Thank you

Enabling EE VoLTE on BTU S7 6.0.1

Hi Guys,
Does anyone know if it would be possible to flash an EE (EVR CSC) onto my rooted BTU 6.0.1 firmware? The BTU 6.0.1 firmware doesn't support EE VoLTE. I don't want to be on EVR firmware because it messes up my dual sim model (G930FD)
VoLTE became active on my EE G920F (BTU) earlier today. I'd been asking the same question as you for a few days. Was messing in the settings, disabled and reenabled wifi calling and it just happened. Phone rebooted itself and VoLTE was active. Tested with a few 4G calls to confirm.
None of the ims files were changed but there is a new APN named 'ims' in the settings. It isn't selected active but it is there - it wasn't before.
Yes, the phone was bought.from an EE shop and still carries the original IMEI. So I believe as long as your phone was bought from an EE outlet you will definitely be able to use VoLTE sometime soon.
Currently running the CarHDRom V.27

Three & EE VoLTE on S8+ XEU/BTU firmware

Hi,
Has anyone been able to access Three and EE VoLTE on ether XEU or BTU firmwares? I am thinking of getting the S8+ Dual SIM but don't really want to have to flash a 3 branded firmware on a dual SIM model if I can help it.
Thanks.
Can't answer for dual SIM variant, but you can do it in a number of ways, you flash the three firmware and CSC, or you flash the EE firmware and CSC. Both will mean you get OTAs. I however used EE CSC and xeu rest of the firmware. I get the best of both worlds but have to manually update using a hybrid of the EE CSC and xeu rest.
I have flashed BTU firmware before with Three CSC but yes it causes a mismatch and OTA updates no longer work ;-(

Question Flash firmware from other regions & Recieve OTA updates

Dears,
I have S908E 22 Ultra, but my country always get updates very late. So the question is if I flashed other country firmware without changing CSC , will I still get OTA updates ?
Yes you will get but those OTA updates will be from that other region only
Hi, I have S908E 22 Ultra, I want to flash the USA or SM-G9880 firmware (or any snapdragon firmware) is OK ?
Also I changed the CSC code but the last line (country of production not change) example: COO/COO/COO after change CSC: XID/XID/COO. It's possible to change the country of production CSC without root?
Can anyone help with the info if can do it or not, only the last CSC (country of production) other CSC I changed with SamFw FRP Tool but like I said I can change the last 3 letters!
Thank you!

It is not possible to change CSC without tripping Knox. You must unlock the bootloader to change the CSC.

Unlock the bootloader and use Odin to flash OXM firmware. OXM is multi-CSC, so you should be able to change region to India.
Don't forget you can use the Search function to look for solutions to questions that have been asked many, many times before.

If you unlock your bootloader, you can install any CSC you want, so you'd just download INS firmware and flash it using Odin.
Or, you can flash the OXM firmware and simply change the region to India, as I stated in my first reply.
Ok i got that now second major issue is that i cannot unlock my bootloader as my developers option is not showing oem unlocking
no need to unlock your bootloader to change the CSC, just use this application to do so

Can you suggest best US based csc with regular ota updates as i am not getting ota update on gcf....stuck on may security patch update....
Can GCF based devices get ota updates i read it in someone's post that they can be only updated via odin or sideloading
GCF gives more LTE and 5G bands support so maybe that's why your phone has it set on that. You can change it to XAA as it's bloatware free and gets regular updates.

Wanted to ask it just out of curiosity....there is no way to change my csc from USA version to Indain version....by any means?
I don't think this is possible... and that's why Samsung has different variants for different countries ...
Okkk....
But by any chance u get to know that it can be changed to Indian csc please do let me know it will be very helpful
Thinking of flashing this firmware update via odin....device model number : SM-S908UZKEVZW
Region:VZW
OP, Are you sure it is an "unlocked" version? Based on he last three charactors of the model# you provided says it is a Verizon branded phone. Yes, technically it was unlocked after 60 days, but since you are not connected to Verizon's network, that may be the reason you are not getting OTA updates.

As for unlocking the bootloader, none of the US variants' bootloaders are unlockable.
I changed my csc code from GCF to USC and now in sim card manager settings it is showing only sim1 option and esim no sim2 option is available

How To Guide OTA update issue

Hello,
I got a samsung galaxy s22 ultra which is a USA model. I was having a concern as when i change my csc code to XAA or GCF I don't get ota updates i have to manually update my phone via odin or change my csc to carrier based ones like usc or usc then i get ota update...My phone's model number is SM-S908U and whenever i try to check firmware on sammobile for my model number it doesn't shows any firmware for XAA....
I did some research on my end and some people are saying that XAA doesn't belongs to SM-908U series of phones it is for SM-S908U1 model.....
I have attached a screenshot of my model number and csc of my phone, can anyone guide me if the firmware and model number of my phone are corrct according to the csc code n all stuff and is there any solution for that ota update problem
your firmware is correct XAA ( AIO , ATT MVNO )
for new Samsung device , if you change original CSC you will loose OTA update
GCF | USA (WORLD WIDE)
My question is that isn't XAA csc belongs to U1 model rather than U models
And for csc part when i got the phone my csc was GCF/GCF,XAA/XAA
as you can see in the picture , i'm talking abot S918U and not U1
I want to know if there is any way to check wether my device was U or U1 software initially....
Because i am javing doubt that the person who sold me this has changed the software manually
