Help Problems after rooting my device

[cookieb24]

Hello,
I have a sprint Samsung s4 SPH-L720. I rooted my phone in October and now I cannot turn on the WiFi. It gives a security message and asks me to reboot. Has anyone heard of this? Someone in one of the other forums suggested to another user to use Odin: Return to Stock, fix soft brick, but it for T-Mobile. Is there one for sprint? Cannot anyone else suggest a fix?
Thanks in advance.

So you rooted 2 months ago and are just now noticing the problem? Are you sure it was not caused by something else in the mean time? Like taking an update, etc?

What software release are you at?
