Credit goes to gerdannuckel on another site for supplying the AC:B .GPD :)
Firstly open up modio, drag your profile into modio. Select "File Contents"
Right click in the window that pops up and select "Inject File Into Current Folder" Select the .GPD file provided.
If It says a file with the same name exists would you like to replace it click Yes.
Once you have done the above Rehash and Resign your profile and inject it back to your hard drive/memory card and enjoy your uplay rewards
By the way same method shoud work for all other games with uplay content it's just a matter of getting the .gpd for the game with the uplay rewards all ready downloaded.
