On the occasion recently bought a very cheap К-50 (the previous owner bought this camera in Japan). There were only two languages in the cell - English and Japanese. I decided to try to make all languages available. I started looking for how to make additional languages available ... and found how to do it...
As a rule, those cameras that are sold on eBay marketplaces have only two languages in the initial settings - English and Japanese. Follow these steps to enable additional languages. Everything turns out to be quite simple. I will try to write in more detail (on the example of K-50):
1) on the computer desktop, right click ... select "create" - select "new - text document" ... create a file, give it the name: 00077750.545
you get a text file with this name: 00077750.545.txt, double click to open it and paste this: [OPEN_DEBUG_MENU] (you can just copy from here, copy the text as is, along with the square brackets)
close, save and rename again: 00077750.545 (already without ".txt")
2) create a second file... on the computer desktop, right click .. select "create" - select "new - text document".. create a file, give it the name:
will be created DEVELOP.MOD.txt... but the extension ".txt" is not needed! need: DEVELOP.MOD (already without ".txt"), the file icon will change..
3) copy both files to SD card.. there may be a folder with photos on the card (this does not interfere) ... and your two files will be next to the folder:
4)Insert the prepared SD card into the camera, then leave the card door open and turn on the camera. The camera will enter debug mode. Immediately after switching on, you will see this picture:
Use the camera joystick to move down to the REGION CODE line.
Set the area REGION CODE to “00” (pushing the joystick left), press the “Menu” button (the screen will turn off) and turn off the camera.
Close the compartment door.
The next time you turn on the camera, additional languages will appear in the language selection:

k-X
MODSET.492 with the line [OPEN_DEBUG_MENU] followed by a space.
turn on the camera with the MENU button pressed and access the lens ROM
K-1
00077970.562 with the line [OPEN_DEBUG_MENU] followed by a space.
DEVELOP.MOD is an empty file of zero length.
K-3
00077760.502 with the line [OPEN_DEBUG_MENU] followed by a space.
DEVELOP.MOD empty file
K-3ii
00077980.570 with the line [OPEN_DEBUG_MENU] followed by a space.

K-5 1.07
00077430.505 with the line [OPEN_DEBUG_MENU] followed by a space.
DEVELOP.MOD empty file
K-5ii
00077681.541 [OPEN_DEBUG_MENU] and a space after it.
00077680.536

P. S. The same principle can be used for the K-70 by creating the appropriate files (00077770.524 and DEVELOP.MOD).
