Ok total noob here, sorry.
First android device, ATT S4, SGH-I337. I rooted it, then removed lots of bloatware. Tonight I saw it appeared to be getting an update, and was afraid of losing my root access. So on this forum I found a post to use Titanium Backup to freeze a few things.
1. AT&T Software update Vxx_x_xxxx_x_x
2. FWUpgrade x.x.x
3. LocalFOTA vx_xxxx_x_x
I did not seem to have #2, but I froze the other two. Questions:
1) do I need to do this to keep my root?
2) is disabling these things a very bad idea?
