Recovering tickets from wallet after reset.

Hello, I had World Cup tickets and a boarding pass in my apple wallet, then today something popped up saying if I do not enter my iCloud password, which I forgot, my phone would lock me out. It gave me the option to reset my phone so I did that but I lost the tickets and boarding pass. I tried to redownload the tickets through the ticketing site but it said they had already been downloaded on a different device even though it is the same device. It says I have to delete them from that device which again is the same device to redownload. How can I get these tickets back?
