The X579 printer in question didn't have the eMMC when my company inherited it.  I have a replacement eMMC installed and I downloaded the only firmware listed from the support site. When i power on the printer I get the 99.39.67 error. I know it is because it has no firmware on it. Anyway I have tried multiple USBs with the extracted firmware on it, only to get an error message "Download Error Unsupported Bundle".  With no other available downloads what can be done? I have tried USB 2.0 and 3.0 styles and various sizes, so any additional insight would be great thanks.

Confirm that the part number you installed is B5L32-60002  16Gb Emmc. 

 

Service documentation states that for this error, if the download fails, it is due to a faulty Emmc.

 

Have you attempted to clear/erase the Emmc before installing the firmware?
