After checking with two separate Panasonic part resources, I have now determined that the Panasonic parts department basically has no idea what's what.
I came to this conclusion a long time ago.
They don't seem to have any clue as to the differences between the firmware disk and the recovery disk for the XP30, or even if there ARE two disks. They just keep telling me that the recovery disk for the XP30 is part number RFKZD5TR006 (which is what the service docs say), and generally ignored my questions about the firmware disk.
I traded some emails a few years ago with the service department on this topic -- but unfortunately, that was in an account long gone, so I can't print out the responses. As I remember, they will not provide firmware disks for any of their players (except perhaps to authorized service technicians). They want you to physically bring in the units so they can upgrade the players. They are worried that you will improperly burn the firmware and end up with a brick -- and will expect them to replace the unit. They feel safer performing the upgrade themselves (and presumably have spare eeproms with fresh firmware that they can swap in if something goes bad).
I was hoping that the parts department didn't have a clue and that the firmware might be on one of these recovery disks or service and calibration disks -- but if it isn't, then they aren't going to provide firmware disks. Unfortunately, they seem to have gotten this call right.
One Panasonic rep told me that I would have to check with an engineer, and that they don't have any engineers in the parts department! The paper insert with the recovery disk as received does not even list the xp30 or others with similiar insides, except the rp56. It does probably do the "recovery" process, as I ran it in my "extra" xp30 and it did reset everything back to the factory parameters, but without touching the firmware, which remained at 302 (and without breaking anything, more importantly!).
This is what one might expect a "recovery" disk to do sans firmware -- reload the factory settings -- does the service manual say it should do something more?
So, I have concluded that Sango's info is correct, and that the most current (and likely the final) version of the firmware is on the rp82v302 disk, which is PROBABLY part# RFKZD03R004, which goes for about $33. Due to the age of the machines and the nature of product cycles, I would assume that this file is the last word on this firmware.
Hmm... Well, with the RP91, we had long ago assumed this to be the case, but we have been pleasantly surprised with new firmware versions twice more. I think that they may continue to upgrade firmware as they continue to service units -- probably minor changes that won't greatly effect PQ. The firmware upgrades will only be applied when units are brought in for service.
Why do you think that Sango's disk is RFKZD03R004? Sango, where did this disk come from anyway? An authorized service tech?
