Any way to recover lost campaigns? Lost 2 of 3

[Bannukutuku]

I did a factory reset on my Nvidia Shield Tablet (Android Marshmallow 6.0.1) and I lost 2 of 3 of my campaigns.  I had 2 character party (Kyra and Merisiel) that survived.  But my 3 character party (Seoni, Sajan, and Amiri) and my 6 character party (Valeros, Lem, Harsk, Ezren, Seelah, and Lini) both vanished.  All campaigns had progessed through all available content on normal.  I only have hope here because the 2 character party survived and I can't tell what that party had that was relevantly different from the other 2 parties.
