For some Miss-Understood our annonce WORLD FIRST, 2 SEC Hope you get in mind :

GB-Key SW no Need Update to Support new FW, coz there's no FW depandancy in our FAST and SAFE Unlock process..that means, if in 5 Sec ZTE Release 50 NEW FW of any Model, GBKey SW will still support that FW without Need to Update... , This is Quality !
