K100D firmware memory dump?

I’m hoping that somebody here might have experienced the following error screen on a K100D and can offer some advice:

The problem began with what I thought might be the nylon gears jamming in the mechanism that flips the mirror. When I pressed the shutter I could hear the motor whirring, but the mirror didn’t flip and the shutter didn’t fire.

After a couple of weeks when all else had failed, I decided to enter debug mode and try the “RELEASE AGING”procedure. And sure enough, after the camera’s first dozen or so attempts to automatically fire, the mechanism seemed to free itself and the mirror and shutter began working again.

Problem solved, I thought.

So I turned the camera off and on again to re-enter debug and switch off RELEASE AGING. But now, instead of the debug menu, what I get is this error screen. Possibly the firmware preparing a memory dump?

For the record, the method I used to enter debug was AE-L plus INFO, then MENU MENU INFO.

K100Ds are so cheap to replace that it’s not worth spending any money on the problem, but if anyone can offer any suggestions I’d be very grateful.

The WAIT HS. . . screen has now cleared.

But the camera now appears to be stuck in RELEASE AGING, and doesn't respond to the button sequence to go back into debug to turn RELEASE AGING off.

So now I've got a mirror/shutter mechanism that seems to be working again, but a camera that refuses to come out of debug mode and let me start taking pictures again.

Debug mode finally cleared. Full control of the camera restored. Mirror and shutter now operating normally. Firmware re-flashed just to make sure. Looks like I've got a working K100D on my hands again, at least for now.

It was probably corrupt firmware all along, even when I first thought it was the mirror motor jamming.

Please consider this thread SOLVED and CLOSED.
