Have you tried removing the batteries for two or three minutes (camera and grip)?
If that doesn't work, what happened when you last tried the firmware update? When you held the menu button down and turned on the camera, did you actually see the "now loading" message and the option to select "yes" using the 4-way controller?
If so, switch to another SD card, download the firmware update again, place the newly downloaded copy of FWDC162B.BIN file on that card, and try the process again. Watch what happens. You should see two steps with the word "complete" at the very end.
Once you see the word "complete," immediately turn off the camera and remove the SD card. Do not reinsert that card until the FWDC162B.BIN file has been removed. Start up your camera and immediately reset everything using the instructions on pages 201 and 202 of the manual. You may also want to remove the batteries again for a few minutes (after turning off the camera of course). Now test the camera again to see if is working.
If that fails, try asking Pentax is there is a hard reset feature on this camera (a series of buttons to press during startup which reloads a very basic set of operating instructions to the camera, for example). You will have to do the firmware update again afterwards. Many devices have a feature like this, which can occasionally work wonders. Manufacturers rarely tell consumers how to do this because it can sometimes do more harm than good, so should be avoided unless absolutely necessary (in your case, it may have reached that point).
If all this fails, you've done just about all you can do. It is time to turn the camera over to the professional repair people. Assuming the problem is just a software issue, it should be a relatively minor repair (costs not too horrible).
