I remember that iOS update, SE even released a post telling people to not update it until they had fixed the app. I was one of those that hadn't updated yet so when they fixed it my token app was working just fine after said update.

I always screenshot the emergency key just in case, one can always copy one or two characters wrong by mistake. Have you tried to contact SE support regarding your token? They are probably the only ones that can unlock your old account. I believe there were people that had a similar issue before that managed to get their account back after talking with SE.
