Help Can I install KitKat?

[Data Android]

Hello all,
I just bought a Galaxy S4 Active that is unlocked and rooted.
The phone has an ATT backplate and ATT software on it.
I went to metropcs and they verified that it is unlocked and I got my service with them.

However, I would like to get the latest android version on it and have no idea how to do that.
here is some of my phone's info:

Device name: Samsung SGH-1537
Android Version: 4.2.2
Baseband Version: i537UCUAMF3
Kernal Version: 3.4.0-784654
Build Number: JDQ39.I537UCUAMF3

Any help is greatly appreciated.

Thanks
