If your device is rootable with CF-Auto-Root there is likely an updated root method available for your device. Today Chainfire released updates to CF-Auto-Root for more than 100 devices. In case you are not familiar CF-Auto-Root allows you to root your device while remaining stock. In other words it doesn't require you to unlock your bootloader, and flash TWRP to get SuperSU installed. You pretty much just run the tool and your phone is rooted. There are a few caveats to using CF-Auto-Root. If you have a KNOX enabled device this will trip the KNOX warranty void status. Also if your phone is encrypted using this tool will wipe your data. Check to see if your device is compatible for what has to be the most simple root method around at the link below.
