I have just upgraded my Note 2 (N7105) with 4.4.2 official stock ROM for Nordic countries. There are two ways to root i.e. CF-Autoroot and Philz Touch + SuperSU. May I ask what is the different between the two? Also, it seems the status becomes custom and OTA is not possible. Managed to get it sorted with TriangleAway, however, OTA will remove root?
