Libra 2 Help extracting hyphenation dictionary from Libra 2

I made new hyphenation dictionary by combining few of them together, installed it on Libra 2. Everything works great.

Now i want to upgrade firmware to new version (didn't upgrade for more than a year), problem is hdd on which i had that hyphenation dictionary was stolen, so is there some way to extract it from Libra 2?

Edit: I know hyphenation dictionaries are in "./usr/local/kobo/hyphendicts" directory, but how can i acces that directory?
