Firmware dump labelled for a 43E2G television; the name gives no brand, board code or version, but the model fits the IRIS range seen alongside it. The RAR is about 4.96 MB, the same size as the 43E2 dumps for mainboard 5800-A3M12G-0P10, which suggests a related image. Confirm the mainboard part number before use, save a copy of the current flash, and make sure the image matches the chip capacity before writing it with a programmer.
