Hey man sorry to bother you, I have just recently learned about these code and I found this guide. I was wanting to give them A try, just from quriosity. But upon me trying even this code I keep getting this message that pops up, saying saying "connection problem or invalid mail code. (For my galaxy s21 ultra 5g.) This also b is not my first obe trying I also had tried another one but it said you may want to try codes for your specific phone. That's what landed me here in the first place. Do you have any idea what I'm doing g wrong? Or is there something something I have to do prior to this?
