Firmware archive labelled SF20GM7 with the references 15-AX9-012000 and EJ20GM2 V2.0. The tokens look like project or board identifiers, but the name does not clearly state the brand or model. It arrives as a RAR of about 5 MB. Before flashing, match these codes to the markings on the motherboard, and check that the image size fits the SPI chip fitted. Read and save the original contents with your programmer so you can return to them if the dump proves wrong.
