Thanks for your post. Do you know if any CSC from the OXM package supports real time network speed on the status bar?
It's this feature below:

<CscFeature_Setting_SupportRealTimeNetworkSpeed>TRUE</CscFeature_Setting_SupportRealTimeNetworkSpeed>

Has Samsung disabled this everywhere? Can we enable it by editing the CSC file without root?

 

[yakapa40]

sorry but i have not extract all cscfeature.xml but for S918B i have not find this option

like i never find how to sign a CSC , i don't know without root , how to modify it

 

[Mozie]

Does changing CSC also help with allowing more bands like 5G and so on?

 

[yakapa40]

sometimes yes , préconfigurations are in cscfeature.xml

 

[ken2028]

Can you make the South American Global unlocked region S23 ultra "B" version (SM-S918BZGUTPA )work at least on the Tmobile / Metro pcs 5G network?

Somehow ATT screwed everyone here, we cant use the B version in North America some report No internet available.
Did they disable the 5G bands?

Is there a mod? The band selection has been disabled. You cant either enable it with the SamFW tool.

Any help or an detailed explanation would help.

Thank you!

Will changing CSC from XSA to INS stop the OTA updates?

 

[yakapa40]

@harry552​

for S918B some people report not

 

[harry552]

Sorry, i didn't understand that some people report that they are receiving OTA updates after changing CSC?

 

[yakapa40]

@ken2028
i don't know , i leave in France

if your CSC is TPA you can try to change to CHO COO EON GLO GTO PEO or ZTO

TPA:

 

[yakapa40]

yes they are receiving OTA updates after changing CSC for S918B and not for older devices
