I found this Firmware 1.3 debug unleashed.
[Edit - 15 July]English version of the software found here.
The original problem was that once you upgraded your firmware you lost the ability to do the key press combo to get into debug mode. Debug mode is used to test and adjust some internal settings in the camera like exposure and autofocus. It's a really handy mode to have access to and I don't understand why Pentax changed it.
This program allows us to add a debug mode to the camera's setup menu. It reprograms the menus via the USB cable. Pretty sweet.
The program is in Russian and I do not have the font installed so I see a bunch of ??????????s all over the place. I wouldn't understand Russian anyway even if I could read the font.
OK, after a little experimenting I've figured it out. More in the full post.
OK, here goes. Install the software (the installation is in English) by following the usual MS installation sequence.
1. Start the program. You can start the program before or after the USB connection and camera power on if you want.
2. Connect your Pentax K10D (or Samsung GX10) to the computer with the USB cable that came with your camera. You still have it, don't you?
3. Turn the camera on.
The program should match the image here. If not restart the program and the camera.
4. Press the connect button as shown.
If all went well you should end up matching the image here. If not then the computer is not connecting to the camera properly. Try restarting the camera, program, and reconnecting the USB cable. If none of that works, try MS' solution to everything, reboot the computer and try again.
5. If all is OK so far, select the bottom radio button (debug mode on).
6. Now press the conform button as shown.
7. Now press the OK button.
This will have no visible effect on the camera and the only way you know it may have worked is there are no error messages and the program should match this image.
At this point we want to disconnect the camera and exit the program.
8. Press the disconnect button.
9. Now press the exit button.
10. Turn off the camera and unplug the USB cable from the camera.
11. Turn the camera back on and after the initial display the screen will display Debug Mode in the upper left corner.
Congratulations, your camera is now in debug mode.
What I like about this debug mode over the 1.10 firmware version is, you can use the camera with no interference from the debug mode and there are no special key combos to get into debug mode.
If you want to see the options available in debug mode, press the menu button and scroll 2 to the right to the setup menu. Scroll up once (or down several times) and the debug menu will be visible. There are not as many selections to choose from as the 1.10 FW if I recall correctly, but this makes it easier to use.
Here are some shots to prove this actually works and shows what's available in the debug mode.
The capture/test mode I looked at and I'm not sure yet what it does. I'll experiment at a later date in case I want to kill the cat.
The AF Test is the one I'm really interested in. As soon as I figure out how to do a proper test and adjust I'll post it. I've included some shots of the AF Test menu options.
OK, so now you probably want to know how to get out of debug mode. It's simple as you can probably tell, but since I got you into this maze I'll lead you out.
Follow the steps to start the program and connect the camera as before up through step 4.
12. Select the Debug mode off button.
13. Press the Confirm button.
14. Press the disconnect button.
15. Now press the Exit button.
16. Turn off the camera and disconnect the USB cable from the camera.
When you turn the camera back on the debug mode will not display and the setup menu will be back to normal.
Well, that's all there is to the debug mode. Getting into and out of debug mode is pretty simple and if it wasn't for the program being written in another language this tutorial would not have been necessary.
Until next time, shot something, will ya?
