Frontier’s Edge will not download on Xbox 360

I was having this problem as well, I was only getting 1% download then it was going back to 0%, I then got a message to say that it was not possible to download frontier pack.

I went to my system settings on the dash board and went to download history, I then re downloaded the season pass, went back to the frontier pack and downloaded it again.

This time it downloaded 100%.

Hope this helps others
