[Android Central Question]

I have an old and new S5 that I want to do a complete transfer of all apps and configuration in particualar, "Beepn'Go" which is no longer registerable and thus unusable but it is still usable on my old S5. I'm hoping to use Titanium backup which requires root access to transfer all of my existing config over like it's the same phone.

I've done some reading on this but have a few questions:

Does rooting the device or something in the process reset it back to factory defaults? This would suck if I wanted to back up my existing config with Tianium backup.

Does it still increase the knox version and thus void warranty. I was wanting to tranfer/save/backup all the config on my old phone, reset it, confirm that the issues are indeed hardware, then do a warranty call on it.

Can I unroot it and restore to factory defaults like nothing ever happened?

Is there any other glaringly obvious flaw in my plan or blazingly simple way to do this?
