I am taking the same steps as you described, however I end up with BCC balance of 0. According to blockchair I should have a couple of BCC left as trade of of the hard fork.
Couple of questions (Mnemonic Code Converter):
1) Do you need to change the default 15 words Mnemonic to 12?
2) Do I need to change the default coin from BTC to BCC?
I tried a couple variants, but still end up with zero balance.
Any help, much apriciated.
PS. Before I came across this tutorial I tried just to import the private key provided by Blockchain itself, however electron-cash is than saying: No inputs found. (note that inputs need to be confirmed)
