Issues on Sony KD 49XD7005 with Krypton

Owner of Sony KD 49XD700 (the main reason of buying was the android for Kodi), after the upgrade to Krypton the app made unfinished loadings from menu to menu. I made the mistake to reinstall it and now don’t even can connect to Kodi repository in order to download my native language. Everytime I get the message “Could not connet to repository”. I am frustrated should I downgraded to 16.1 basically is this possible or waiting a miracle? Thanks and really amazing work, I am pleased for the Kodi experience.
