Hi Experts

I was trying to root my Samsung S4 GT-I9506 and got this issue. It says Firmware upgrade encountered an issue. Tried Odin Keis , failed. Keis does not list my phone while trying to do emergency firmware thing and Odin does not detect my phone as well ( i think). Can I get some help to fix this issue

Some more information pls.

Official firmware or custom like cyanogenmod?
Custom recovery installed?
Did you try to flash CF-Autoroot?
