How can I completely remove/erase/wipe/format my S6 EDGE like removing everything from AT&T?

[AC Question]

I want to have S6 with its OS as if it was just taken from Samsung factury. I don't want to have anything from AT&T at all, not even the start intro thing, like nothing. Does anybody know?

Welcome to the forums!

You can't do that without rooting. The only thing you can do without rooting is to install package disabler pro from the Play Store and disable the AT&T bloat, it won't change the boot animation or the boot sound.

Now even if you root, I wouldn't delete all that, you do not get the space back anyway, I would still disable the AT&T bloat.
