I have an old Galaxy Tab here that is sitting on Froyo 2.2. What I would like to do is update it to at least KitKat. 
I rooted it with Z4Root, Superuser is installed and checking with Root Checker, it says it is Rooted. 

So now that I am this far, what do I need to do now to install KitKat(apart from finding the Kitkat ROM)? I have Odin ready to go if that is any help. 

I have also tried CWM, but the device isn't listed. Also, how do I check if the bootloader is unlocked? Or does rooting do that already? 

Hopefully someone can help, as currently the tablet is pretty useless with being stuck on Froyo. I have never installed any ROM's before, so hopefully the above is helpful.
