A pulling technique does fine for one Android things to do before rooting Android gadget, which doesn't mean it works for you. You should think unmistakably about your gadget explicit. As indicated by the gadget explicit, discover a suite establishing technique.

I have a few thoughts about this.

  1. Kind of spammy. So I'll share a few more things.
  2. I haven't had to root for years. You didn't tell us why we want to root out Android phone. Big omission there.
  3. The times I did root it was to disable apps that were locked down by the carrier (Sprint) and even then I found zero difference before and after save a little more free space which in the end wasn't worth the effort.
  4. To root I went to XDA Forums. Much better source than your link.
