I, of course, have the same issue. It is still not resolved (see
this thread).
Try turning on live view and see if you get the bouncing picture fault. If that happens then we can see this as a common fault that affects a number of K20d.
I don't think it is the fault of the firmware update itself. It probably is just the update the triggers this fault in a camera that is already faulty.
Good luck having this thing repaired. Apparently the repair needs a really specific piece of software, which only Pentax USA and Pentax Japan have access to
. Please keep up us to date on the progress.
