Firmware dump named 450 G2C, fourth copy, an 8.00 MB binary without a file extension. The name gives a model designation only; brand, motherboard number and the meaning of the C suffix are not stated. An 8 MB image matches a 64 Mbit SPI flash chip and can be loaded in any programmer software as a plain binary. Compare the different copies of this dump, verify the board on the bench is the right one, and back up the original chip contents before reprogramming.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
