From what I have read zephyr's server is down making it unusable, but there is some leaked cracked version which is suppose to be the original beta version of zephyr (v1.0.0) or something. Im guessing you don't even have the cracked version of zephyr ViperGTR3g, so really if you cant use zephyr you dont have zephyr. As for FIGJAM it seems like he actually knows zynastor and has been given the latest version of zephyr personally, now that must be hard to get? Last version of zephyr I remember using was v1.0.2
