Samsung firmware archive named S310X Plus, 5.39 MB in RAR format, noticeably larger than typical monitor dumps, so it may contain several files or a bigger image. The name does not state the device type, chip or version, so inspect the contents before using them. Flash dumps are normally written with an SPI programmer after reading and saving the original chip. Make sure each image matches the capacity of the target memory and that the board in hand really corresponds to this model before reflashing.
