Firmware dump for a Federal FD-9075 device built on an MT89J-58 board, intended for an EN25F80 flash chip. The EN25F80 is an 8 Mbit (1 MB) SPI memory, which fits this 909 KB RAR archive. Such dumps are usually written with a programmer such as a CH341A to recover units that are stuck on a logo, boot-looping or completely dead after corrupted firmware. Verify the MT89J-58 marking on the PCB and the chip label, read and keep the original contents, and check that the extracted file size equals 1 MB before flashing.
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 @tamirkaran_chanel. Enginerys does not host this file.
