Root How do I take my Fascinate back to Stock?

[chicagoland8]

Hey guys,

I bought this phone online and it was rooted and has a custom ROM installed. However, the past few months it's been terribly slow and I was hoping to do a factory reset to speed things up, but I don't think I can do that with my custom ROM. I'm not even sure how I identify which custom ROM I have. Can someone point me in the right direction?

Thanks!

try this. just do the odin steps. Not the root steps. U will have a factory stock phone afterwards.
