I need help guys. My s7 edge used to be on the United Kingdom/Ireland XEU firmware with the XEU CSC but recently I deep clean flashed the latest BTU firmware with the PIT file for re-partitioning. However, the Samsung Info app shows my active CSC is still XEU and for that I cannot receive OTA updates on my phone. I flashed the 12th March 2018 BTU firmware and recently a new OTA was available from the 28th March 2018 or somewhere on that date as Sammobile says. How do I go about getting the default BTU/OXA CSC on my phone???
