Successfully done. Wow! Thank you so much. Now on UI 6.1 lastly sir, can I change the CSC from XAA to either THL or INL? So I can enable call recording?
Yes sir. And manually too.
This is how I filled it manually:- Model :- SM-918U
CSC :- XAA
IME :- I inserted the phone ime number.
Still the same error message.
Thanks for all your replies.
