does flashing count as rooting? just asking… new here…
No my friend. Flashing stock firmware on your phone restores it to it\’s original state. Rooting modifies your phone\’s software and voids the device warranty.
You can flash stock firmware to restore the phone to it\’s initial state if you previously rooted it.

Hi! is there a software for mac os?
Not really! You\’ll have to extract and manually flash the IMG files via fastboot/ADB if you want to use Mac OS. At this time, I don\’t think there\’s a publicly available tool, yet!
You have a firmware for my phone MyxI1.
