Unroot Galaxy Note II, Android 4.3
So I have rooted Galaxy Note 2 Android 4.3 and I learned that I can' t update my firmware through OTA update it says "Your device has been modifies yada yada yada" So I searched on internet how to unroot and it says first use flash counter TriangleAway and then full unroot from SuperSu option.
I read that TriangleAway will possibly brick my phone so to be sure I predicted the future with a Magic 8 Ball and received the answer "Yes Definitely". Lol
So I am asking should I really need to use TriangleAway in order to update through OTA? Can't I just full unroot and do the OTA without using TriangleAway?
I know that it will appear the yellow triangle but I think after the update it will go away.
