In order for this to work.
You need to download Bitcoin ABC - then leave your PC on for about 3-4 days, so that the BlockChain information gets downloaded, you would need 130GB of space on a HDD you'd be using.
You also need to have a wallet which where you had BTC in there between 31 July - 1st August. Wallet can now be Empty and you need to be able to Generate Private Keys from that Wallet.
Then using Bitcoin ABC, you need to use the Console to insert the PrivateKey.
I will need to find a link to the tutorial I used which worked. Will link the Youtube video later.
Kind regards,
