[q] gt-i9505 does not support initialising topic

Hi
I try to update my Samsung S4 using KIES but get the error GTI9505 does not support initialising.

When I dial *#1234#
I get the following version information

AP: I9505XXUDMH8

CP: I9505XXUDMH8

CSC : I9505OXXDMHA

Can you tell me how I can update my phone?
