Just attempted to root my galaxy s4 tmobile. motochopper method: How to Root Galaxy S4! - YouTube I used the motorchopper method and it installed super user, but super user doesn't work. Super user says : the super user su binary must be updated. then I tried twrp method: when I tried to boot into twrp mode it didn't give me the desired screen (it gave me a list of 5 small blue text options- reboot apply update....etc and there was a picture of a dead android guy with No command underneith, but this wasn't the desired twrp menu). Why doesn't this work? Could it be because I got the update? How do I check if I got the update? Is there anyway I can revert to my stock s4 without all this rooting crap I put on it? I will just stick with it as is for now until someone makes a tmobile rooting tutorial. Thanks.
