Firmware dump for a Suniya board marked SU-4392, packed as a 9.41 MB RAR archive. The name points to a Macronix MX25L6405D flash chip in an SO8 package, a 64 Mbit (8 MB) SPI part, and the dump is labelled as fully working. Technicians write such images with a CH341A or similar SPI programmer, either in circuit with a clip or after desoldering the chip. Read and save the original contents first, confirm the chip marking matches, and check that the extracted image is exactly 8 MB before programming.
