Hello,, I recently got a Galaxy note 2 GT-N7100 and I decide to root it using the following method (http://galaxynote2root.com/galaxy-note-2-root/how-to-root-galaxy-note-2-easiest-method/) and it really works. For example, I saw the installed Supersu app and I am able to use Titanium Backup to restore and backup stuff. However, the supersu app disappears after a while and I the Root Checker app also says that my device is not yet rooted (so I download Superuser instead) but I am still able to use to Titanium Backup app but it doesn't show the "Titanium Backup has been gained Superuser permission" message..How come? Thanks.
