SPI flash dump for the Samsung UA23H4003AR television, taken from a Winbond W25Q32 chip; the 4 MB file matches that 32 Mbit capacity. E457 in the name is probably a board or version code but is not certain. A clean image like this is used to fix boot loops, standby faults or a frozen logo by reprogramming the chip with an external programmer. Make sure the board carries a 25Q32-class flash, read and keep the original data, then write and verify before reassembling the set.
