Can't find download history

You should be able to find it on your download history, i can't remember how to access download history on my xbox but i think you press the guide button and then go to account setting and find download history. If you can't find your download history on
the xbox you can view it here, you just add the map pack to your download queue and it should auto download when you connect to xbox live next time: https://live.xbox.com/en-GB/Download/History

Where is download history. I can't seem to find anything since the upgrade

Even if it didn't complete it should still show up in the download history. Read this to make sure you're accessing the download history correctly -

support.xbox.com/.../download-content-history

If you still can't find it, call support.

No , you really can't do anything , the offer for the blue flaming helmet is gone. They realesed the helmet for the 10th birthday of Halo and it's no longer available.You can ,MAYBE, find your helmet if you already downloaded it in your download history.

You can't download the blue flame.

You may need to download the games from within the trilogy app. See if there's a way to open it up. If it was never downloaded and you can't find it on your hard drive then go to the download history of the account that made the purchase to redownload.

You can access your purchase history on the dashboard by going to System>Accounts>Download History.
