I was trying to access my BCC balance from my now empty of BTC Blockchain wallet using the 12 recovery words from blockchain.info when creating an electron cash wallet. I hope that makes sense.
What would I change the network settings to?
I have also recovered my BCC from blockchain.info wallet using same method you have mentioned above with electroncash.
I think either your electroncash is not synchronized or you might not had any balance during the time of fork.
