Firmware dump for the LG 49LF540T television, taken from an MX25L8005 SPI flash, supplied as a 176 KB RAR archive. The MX25L8005 is a Macronix 8 Mbit (1 MB) serial NOR chip, so the extracted image should be exactly that size. Flash it with a CH341A or similar programmer when the set fails to boot or loses its settings. Read and save the original contents before erasing. Confirm that the chip on your board carries the same marking, as a mismatched image may not fit or run.
