I used dictutil (Windows, I am not able to to understand how it works on Linux) to insert the dictionary I want instead of the standard dictionary but after synchronization I had again the standard dictionary. Before it I tried to give the read only flag, both Linux and Windows but it did not work.
May be something is changed in firmware? Or I am doing something wrong? But the dictutil told me that it was OK
Code:
C:\Users\paolo\Desktop\Dizionario-italiano\Kobo> dictutil-windows.exe install dicthtml-it.zip
Found Kobo eReader at "F:" with firmware version 4.20.14622.
Installing dictzip "dicthtml-it.zip" (locale: it) as "dicthtml-it.zip" (overwriting_builtin: true) with label "Italiano".
Copying dictzip.
Note: firmware version >= 4.20.14601, so using new method for preventing nickel from overwriting dictionaries.
Wrote dictzip to "F:.kobo\\dict\\dicthtml-it.zip".
Updating ExtraLocales.
No need; replacing built-in dictionary.
Updating database.
Note: the dictionary table is unnecessary and inconsequential in firmware 4.20.14601+ and can be safely removed.
