Pocketbook Era - Language Support

Hello everyone,

I have been trying to get Russian–English and Russian–Russian dictionaries working on PocketBook Era PB700 (firmware U700.6.8.4183), but nothing seems to be compatible.. So far I have tried:

1. KOReader ZIPs (including older versions to 2022)

Result: ghost apps @koreader in “Users” but do not launch.

2. KOReader PBI installers/older builds

Same result — launcher refuses to run them.

3. Factory reset/clean install

Same result

4. Manual dictionary install

Tried .dic or StarDict files but the firmware does not recognize them. It seems there is no easy way to add dictionaries to the native system. The OS no longer allows raw StarDict files.



I understand that the firmware might block unsigned apps, and that native dictionary import may be limited. I am looking for a practical solution - thank you in advance for any advice))
