I am currently working on updating a KM4050 machine, but it seems to keep coming up with an error code stating that the full firmware is not in the flash drive. But I have extracted the firmware into a usb stick, but it still gives me that error. It says that the complete file is not found, but I downloaded that firmware directly from the KYOCERA Australia website through a secure login username and password my boss gave me. It also reads ip server not found. I even tried sending the dimm back to Australia to have it programmed as it was a new dimm, but it still gives me the errors. Need help urgently.
