Krypton automatically installing?

Hello.
How do I prevent Jarvis 16.1 upgrading automatically to Krypton. It does this after a power outage.
If I could install my 16.1 setup/favourites etc. to Krypton then I’d use Krypton but my 16.1 setup doesn’t install and I just get a ‘migrating to’ which never ends.
Can anyone make a suggestion. I’m using a Sony Bravia internet TV.

Thank you.
