[Q] No Root Access after Rooting! WTF!

view story

http://forum.xda-developers.com – I feel like I successfully rooted my Tab2 10.1 GT-P5113 using odin. I have cmw recovery and flashed root file with no errors. After rebooting I have the "#" Superuser app. It says SU binary needs to be updated and when I try it says installation failed! Apps that require root tell me that it cannot access root. Used root checker and it also says I don't have root. What am I missing? (HowTos)
