Hi. Just a bit confused about my CSC. Currently my phone is on AP: I9505XXUEMKF with CSC: I9505BTUEMK5. As far as I was aware, this is an unbranded CSC for the UK and Ireland? (I am in Ireland). Now my phone was locked to a network but I got it unlocked and the CSC is now this. According to Sammobile, the latest firmware for BTU is I9505XXUENAA but when I connect my phone to kies, it says i have the latest update? Am I missing something big here?
