Hello guys! My galaxy S4 I9505 is rooted and there's a new version of the stock ROM. I've read a guide which makes use of TriangleAway to temporarily "turn off root", so you can apply the update using OTA. I'm not sure what OTA means so I'm not sure if this works. I wanted to ask you guys if it's safe to "turn off root/SuperUser" and install the update through the device (not kies/odin). Thanks a lot.
