If a TB8163P3 device enters a "soft brick" state (boot loop) or "hard brick" state (black screen, no response), the BSP provides the scatter file and raw images required to restore the device using the Smart Phone Flash Tool (SP Flash Tool). This recreates the partition table and writes valid firmware to the eMMC.
