Awesome! As Tallica said, you can use this link from his signature to *UNROOT and get back to STOCK*.
There's a possibility that this *may* not fix your issue, depending on what this guy messed up, but it's likely.
Just read up over there, and if you don't understand anything, ask us first and we'll help you before you flash anything
On the other hand, if you don't wanna unroot...we can get that working for you too!
