I tried using coinomis guide here:
https://coinomi.freshdesk.com/support/solutions/articles/29000013719-how-to-get-bitcoin-cash-from-many-wallet-software-services-with-coinomi

but when I use that mnemonic code converter it doesnt give me the specific addresses that held my bitcoin and should have my BTG, it derives I think an infinite ammount of addresses but I can't search through them...

I had the BTC in my mycelium android wallet, I even tried to just restore that in the coinomi android wallet but still it shows 0 BTG

:/


EDIT: when importing my BIP39 12 word mnemonic seed from Mycelium into coinomi (after fresh install > restore wallet) I also inputed my BIP39 passphrase from mycelium and that is why it didnt work.

follow this guide (don't forget step 0) exactly and it will work.
