The refers to the Samsung Galaxy A03 Core. This is an entry-level smartphone that runs on a Unisoc (formerly Spreadtrum) processor, rather than Samsung’s own Exynos or Qualcomm Snapdragon chips. This distinction is crucial because Unisoc-based devices use fundamentally different flashing protocols and file structures than their Exynos or Snapdragon counterparts.

Unlike Samsung’s typical Odin-based firmware (which uses .tar.md5 files), the file format is unique to Unisoc (Spreadtrum) chipsets. PAC stands for "Package" and it is a proprietary, compressed container format that holds all the partitions required to flash a Unisoc device: boot, system, vendor, userdata, modem, and more.
