Hi, some time ago I did S8 G950F U9 single sim to dual sim ,
now I need back to stock for working Google Pay.
If I run Google pay and I want to add card, I get error "this phone can not be used for paying, maybe it is rooted "
My knox is 0X0, phone is not rooted.
Any idea, how to get all back?
BTW,I did all changes with Z3X
