I have tried to update my galaxys9 using ota but I get the error ‘your current software version isn’t supposed . ‘ visit a service center.
after days of finding solutions I tried to use smart switch but it says my phone is up to date.
the other option I tried was a manual update using odin but I still get auth. ADL errors my phone is sm-g9600 and I am 100 percent sure iam downloading the right firmware what could be the problem.
