Flash dump for an Iris Sat LCD television, model 24S20, packed in a 3.85 MB rar archive. Neither the mainboard code nor the memory chip is named, so look inside for a readme or chip marking before use. Technicians use such images to rewrite the SPI flash on small LCD TVs that boot-loop, freeze on the logo or lose their settings, using a programmer such as a CH341A with a clip. Back up the original contents first and verify that the chip type and size on the board match the image.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
