I tried to root my Samsung Note 3 phone with Odin and this cf-auto root file – CF-Auto-Root-hlte-hltexx-smn9005.zip. Unfortunately, it failed. I was getting this error message – Fail (Auth) on Odin Log. May i know what does it mean? Is it some kind of authentication failure? How to fix it? In fact, i want to install TWRP on the Samsung Galaxy Note 3. Before I can do that, the device needs to be rooted.
