Thanks Everyone I've sorted it. Homebrew is now installed I have a backup of the system. I think it was my internet speed. When I used a phone it worked. I've also used a 32gb SD Card but that failed at first.
If anyone else has this problem you need to set your phone as a hotspot. When you boot into safemode to install CFW you may need to turn the hotspot off and back on (my phone didn't like the fact I tried to reconnect after shutdown... it already thought it was connected).
