Firmware dump for an Iris Sat LED television, model 43E4600, using a mainboard with part code 5800-A6M70E-OP30. The 5800-A6Mxxx numbering is typical of Skyworth-built main boards found in many rebranded sets. The 2.94 MB zip is used to reprogram the board SPI flash when the TV boot-loops, freezes on the logo or stays in standby. Match the full board code printed on the PCB, read and save the existing chip first, and confirm the flash size matches the image before writing.
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.
