Second 4430S firmware image, marked (2), 4 MB raw binary. The name shows only the model number, with no board number, revision or status. Two separate dumps of the same model let you confirm in a hex compare that a read is consistent before using it for recovery. It fits a 32 Mbit SPI chip and is written with tools such as a CH341A or RT809. Back up the existing chip, write and verify the image, and check that the PCB matches first.
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 @biosfilebins. Enginerys does not host this file.
