I downloaded and successfully updated my firmware on my 5201 with the firmware on Pioneer's site for the 5200. After noticing that my Radio Tuner was missing in the source list and my eject functions no longer worked, I back-tracked and realized my mistake. Has anyone else encountered this or have any idea of how to go back? I've been trying to install the proper 1.06 firmware over the currently installed 1.08 and I get the version error message.

or is there a way to force the unit to install firmware on an attached USB drive?
