I have a mac and I have followed multiple guides to root my gs4 with motochopper. When I'm connected to wifi motochopper says everything worked but on my phone a security message pops up and says that a application attempted to access my system and has been blocked (or something like that.) then my phone restarts and i have superuser and when i click on it and try to install what it says to do it says there was a error...also Im still not rooted. When I'm not on wifi everything happens the same except the security message don't pop up. What do I do to get my phone rooted? I have a gs4 version 4.3 model i337 baseband version ends with MK2.
