Original Firmware

• Updates from the manufacturer are supplied as three files which are copied to the player's root directory via USB:
  • YPK5.AUI - This file is identical for all firmware releases of the K5. It probably contains instructions for the boot ROM on how to perform the update. This file is tagged "Telechips AUI Solution".
  • YPK5.ROM - This file is probably the bulk of the firmware.
  • YPK5.IMG - This file probably contains the graphics for the UI.
