Archive for the Samsung SM-J260G, the Galaxy J2 Core smartphone. The name gives only the model code, so it is unclear whether it holds firmware, a repair file, a schematic or other service data, and the contents should be checked after extraction. Samsung firmware and repair files depend on the exact model and binary version, so compare the model code and bootloader revision on the phone before using anything inside. Keep a backup of the device data and partitions before any flashing work.
