I have an unlocked Galaxy Nexus. One of the reasons I rooted it is to use Catlog (as you may know, Catlog requires "super user" priv.). The headache is, every I upgrade the OS on phone (downloaded automatically, then keep asking me to install the upgrade), I have to go through the rooting process again. Does anyone know why the upgrade would undo the rooting? Anyway to avoid it? TIA.
