For future reference, unless you're returning the device, never relock or go s-on. And I personally don't go s-on for that, especially on T-Mobile. If you ever have issues like this again grab the RUU from HERE
and run it. It'll put your phone back to bone stock firmware and you're still unlocked with s-off.
