this is original firmware, so root is not included
tar file (not zip) can be flashed using odin3 (see example on screenshot, wipe phone before/after flashing)

yes, this is 100% original release from samsung, it is offered via Kies for users from Switzerland with SGS under operator Sunrise.
It is not on sammobile because they don't have information about SGS from Sunrise Switzerland (SUN) and some other models.
This is not first time when I post firmware from Kies which is not posted on any other websites.
