Default [Q] Help! Won't update. Says it's rooted even if it isn't!

Hi, so I rooted my phone a while back and unrooted it right away. I tried to update it but it says it's rooted. I've checked using apps if it was rooted and it said it wasn't. I've tried using the Restore Error via PC Suite but still won't update. Please please please help me!

Keeps saying software update unavailable as well.
