Raw 8 MB binary firmware image whose name offers little detail: HK.T.S2T512CP639 looks like a mainboard or project code, but no brand, model or chip is stated. An 8 MB size corresponds to a 64-Mbit SPI flash, common on TV boards and many embedded devices. Identify the target board from the code printed on the PCB before use. Read and save the original chip with a programmer first, verify the chip is 8 MB, and compare the header against your backup before writing.
