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?

This is not working my Samsung galaxy S21+ factory unlocked One UI 4 Beta, what could be the reason? or there is alternative code

Secret codes do not work on Verizon so I guess it don't matter if you own the unlocked phone or not either way you don't really own the phone apparently Verizon thinks they do pretty stupid

Wow, cool post about iothiddenmenu. I’d like to write like this too – taking time and real hard work to make a great article… but I put things off too much and never seem to get started. Thanks though.
