I changed CSC successfully on my S21 from VZW to XAA. Then I was able to install more than one eSIM profiles. Previously Verizon had restricted it to only one profile. BTW, it changed to XAA/ATT from previous VZW/VZW so I am thinking may be originally this was an ATT phone. I had bought it used and transfered my Verizon number to it. Thank you for the tutorial.
thank you so much. This is really helpful. I bought an unlocked S21 from ebay and it does not have wifi calling. it has U1 firmware CSC is TMB/TMB, TMB/VZW. I really want wifi calling due to spoty connection. Following the instruction, I change CSC to XAA, the volte calling option shows up but wifi calling options shows up for a second and disappear.

Very nice video man! I have an inquiry to make you seem like a knowledgeable person: I have an XAA/XAA, XAA/ATT s22ultra which doesn't receive OTA updates where I live outside of the USA. Some guy on reddit said that if I switch to the CSC back to an American one, I should be able to receive OTA updates again. I don't want go risk anything without having a confirmation.
Sorry for the lack of response, i really dont have time to check this stuff very often if you change your CSC to XAA, it should give you the latest updates as soon as they are pushed out for your device. There is no risk in doing this, as the CSC can be changed as many times as you want. By the looks of things, you are already on XAA, but your device was originally from AT&T. This should not affect the updates.

Hi i bought my s22 ultra from india now i am using my phone in canada it doesn't work with 5g and Samsung wallet is also not working what to do without loosing data and please also tell me can change back to indian version
The default/unbranded CSC for phones sold in India is INU. Devices sold outside of the US and Canada likely will not connect to the 5G network here due to the bands being different in the two regions. The phones sold globally vs North America are also different, so the CSCs are likely not compatible.
I read on Samsung Canada members forum that an owner with a Vietnam Galaxy S23 phone changed his CSC from XXV to WWD and then was able to get 5G working on the Rogers network. Perhaps that will work for you? Only issue is updates won't work unless the CSC is changed back to the original.

Follow the tutorial, and make sure to use CSCs that your device supports. US/Canada devices are different from the ones sold elsewhere. You can search online for the CSC you need for your country/region.
if i go through the CSC change process and later need to factory restore my phone, will the CSC be reverted back to its original one or will the CSC change using SamFW be permanent?
no it does not I just did it on my Samsung S23 ultra to get the spam call filter option on it and I did not have to root the phone. You do have to tell you antivirus and firewall to allow this program to run because it does detect it as malware. There is no malware its just that it does not have a digital signature and the scrips it uses are detected as malware. I live in Mexico so I flashed the CSC IUS which is one of the CSC for Mexico and got the feature I wanted.

so my phone is TMOBILE and i found i can flash using stock firmware using odin with the TMobile CSC, but that'll just reinstall all the TMOBILE bloatware with that firmware right? And this method you're showing is to flash the firmware to an unlocked phone, which contains no bloat? Thanks!
This tutorial was done on a carrier device to show the process. It's the same on both carrier and unlocked devices, but XAA requires U1 firmware if you want service to work. U1 firmware by default has no bloat, but the 4G/5G logo is changed, and you lose dialer codes and certain features within the phone app from what i noticed. Carriers also show the 5G logo when you are using LTE, which i dislike. You can just change to XAA once you flash unlocked firmware if you want, and it is identical to a factory unlocked device in the US.
Also note if you want to flash U1 unlocked firmware, you need a patched version of odin, or else it will not flash. You also want to use CSC instead of HOME_CSC in odin. User data has to be wiped when changing firmware to a different model.
