actually been to busy to try and since I have other phones that are rooted like my nexus 6 and my Note Edge it keep's my Flashaholic tendencies under control , maybe this weekend ,I've been wanting to try out Viper Rom since my M7 , i'll keep you posted but as far as the rooting tool on this thread goes I'm not so sure the developer never chimed in and it doesn't seem like that many people have tried it , and like I said No One replied so I took that as a Bad sighn , there are more then one way to skin a cat , this will be rooted soon enough , my Note Edge and N6 and Note Pro 12.2 have been keeping me busy...............
