Today I did a very stupid thing on my S10.
I found an AT&T sim card on my house because my parent bought an iPhone 12 pro max on a trip to the USA and the phone had this AT&T sim card. I inserted it asked me to restart my phone and now I have every app of AT&T and my mobile data button is not located on the notification panel anymore. Is there any option to bring back my old phone? I don't even live in America.
What have I tried so far:
- Factory Reset the phone
- Master Factory Reset
- Flash With ODIN and Samsung Tool Pro tool
When I flash it finishes successfully but when turning on Installing System Update Fails. And takes me to recover mode when I reboot it shows the AT&T logo during boot and it's the same.
Can you help me?
Thank You in advance
That's the first thing I tried and it didn't work and all the pre-installed apps and mobile data option is removed from notification panel its pretty frustrating to be honest
