My dad passed me his old S23 Ultra, which he bought from a local store. When he bought it, he said he checked the IMEI and it was a genuine Samsung one. As i reset the phone when i got it from him, I ran with it for a few days, and noticed Samsung Pass, Wallet and Secure Folder are not working. Knox isn't tripped, it's (0x0). After that, i checked the IMEI and i see it looks like a Sony XZ3 one. This phone had a baltic/british csc(i'm not sure anymore). I changed it to EUX. Do i need to manually flash the newest software with Odin?
