Can I flash Canada Firmware in S23 Ultra (SM-S918B)

[mnijhum]

Hello, 

My device is bought from outside Canada. The 5G bands are locked in Canada so I wanted to flash the Canadian Firmware via Odin. Can I do that in SM-S918B? If yes, which firmware should I flash?

No, you can only Flash the Canadian Firmware on the US SM-S918U / U1 devices. Likewise you can Flash the US U/U1 Firmware on the Canadian SM-S918W.

So, can i flash from S-s910w to US verson? It will wipe all my info, or it's just patch?

No, it's not "just a patch". You are Flashing the FULL US Firmware. 

After you are running the US Firmware, you will need to Flash the Canadian CSC and Modem to get your Carrier services, ie: WiFi Calling etc.

If you Flash the Canadian Home CSC, you might not lose your data, but you may be forced to Factory Reset, so have a RECENT Smart Switch backup.
