I'm trying to understand the root process as it currently exists.

Keep in mind that my current device is a Samsung Galaxy Tab S 10.5 model SM-T800. It's a wifi device without cellular capabilities, so it is not through a carrier.

My first Android device was an Asus Transformer. I could get root because there were exploits (particularly regarding PDF if I remember right) that could grant root privileges. Of course, OTA updates would undo it and fix the security hole that allowed it.

Currently, it seems to no longer be a feasible method.

To make sure I'm understanding things correctly, please correct my understanding (or lack of) below.

The current preferred root for most devices is cf-auto-root. It will grant superuser (root) privileges and then flash the stock image from the device manufacturer. Alternatively, you can flash a custom recovery image. Do I understand this correctly?

Assuming that is correct, are OTA updates possible? Will those OTA updates break root?
