Hello!
My father has a Samsung Galaxy S4 GT-I9505 and it has modified so he can use not only T-Mobile SIM Card, but also use the Vodafone and Telenor SIM Card. Now he wants me to update his device to its latest version but it cannot update a device that has been modified.
Any solution of how to update a modified device without having to remodify the SIM Card codes?
