Priority #1 should be the wallet.
Can you restore a wallet on coinomi with wallet.dat? If so, how?
Coinomi is a trusted and proven software. Yes you can make back ups, see their website for answers to these questions
When trying to find these things out you always end up in a labyrinth of information inbetween websites, github and a million other places...
It would be highly appreciated for someone to have knowledge about for instance backup on icoinomi, to just simply post a bulletpoint list of what actions to take...

All greatly appreciated!!!
