I have a new GS5 t- mobile GM G900T Android Version 4.4.2.
I am a mac user (Mac OS X) 10.9.4.
I downloaded Towelroot, SupuerSU, WiFi Hotspot & Rootchecker. Everything worked great. I was rooted!
Later that day I noticed severe battery drainage and my G5 was warm to the touch. Concerned, I uninstalled everything and attempted to re-enstall all Apps.
Now when I download Towelroot it states that "this devise is not supported". SuperSU now states "There is no SU binary installed, and SuperSU cannot install it. This is a problem!
I would like to be able to root my GS5 again.
