Finally sorted it! Thanks. Yes, I did follow step 3, but I had to modify it to get rid of an SSL error: openssl enc -d -aes-256-cbc -md md5 -a -in bitcoin-wallet-backup -out decrypted_wallet

Also I had to insert an additional step before step 5 to decrypt the PIN-protection I had set for sending bitcoins on the phone. If you have set a sending PIN on your phone and you don't do this step you won't get your private keys at step 5, only the public keys and initialisation vectors etc. You need to run: ./wallet-tool --decrypt --password= --wallet=decrypted_wallet.

I found the instructions for wallet-tool very helpful also: https://github.com/bitcoinj/bitcoinj/blob/master/tools/src/main/resources/org/bitcoinj/tools/wallet-tool-help.txt

The whole process is a bit long-winded, but it does work and I have finally recovered my Bitcoin Cash from my phone after the split - Whoopee!

Thanks for all your help.
