2degrees NZC CSC september security update

Important Announcement

The final feature update for the Galaxy S9/+ has been rolling out globally called OneUI 2.5. It may take extra time for us to get this OTA in New Zealand but if you are comfortable you are able to manually upgrade by downloading the firmware using Samfirm then flashing it in download mode using Odin3 v3.13. Remember to use the HOME_CSC file instead of CSC and download the DBT region firmware from Samfirm as it is OXM compatible with NZC/VNZ/whatever NZ handsets.

And on VF.
