Oops..I used electron cash to sweep the uncompressed blockchain.info private key. And I used
https://www.bitaddress.org/ to uncompress that key. Hope this helps.
Wow,sounds like you have complicated the process further ! Let me guide you to a cleaner way,
1.Do you have the uncompressed private key (scannable) from the blockchain.info address ?
2.You can download the coinomi wallet and scan the private key from blockchain.info there.They have a BCC wallet so you shall get your coins.
Seems less complex and trustworthy as I have did the same without any problems.
Considering the process is complete, I think you're the one complicating things.
1. The private key from blockchain.info was compressed, not uncompressed, I had to uncompress it myself.
2. No I couldn't. (Tried that days ago, and it didn't work).
What worked for you, won't work for everyone.
