Hello,
While having bought a PB360° in Germany, I was astonished that there is no DE-RU keyboard layout, allowing to switch between German and Russian keyboards. Thus I created a new keyboard layout specially for this purpose. Also you can use this file as a template for your own keyboard layouts, which PB does not provide (like, for example, French).
The layouts do differ from the official German / Russian layouts in PB360, but I think they are even better, as they contain more special characters. Of course you can adapt them to the official layouts with a text editor (I recommend PSPad as it interprets the encoding correctly).
DE layout:
RU layout:
To select a custom keyboard layout, you need to copy the KBD file into the \system\language\keyboard directory on your PB. Then you can select it in the settings of Pocketbook.
File updated.
