What steps did you follow? I use Coinomi but I still have not recovered my BTG. I don't want to compromise myself. I have seen too many horror stories about BTG.
Phalo, the steps for retrieving your Bgold if you already had BTC in Coinomi are different than if you are retrieving it in Coinomi when your BTC was already in Coinomi
Below is the link for retrieving it in Coinomi. All you have to to protect your BTC is move it to another wallet first.
