I am having trouble rooting my Kyros. I watched the video and downloaded each of the files to my SD card but when I try to open the z4root it tells me that it "can not open". What have I done wrong? I'm not very tech savy so it could be something simple. Any ideas? By the way, just downloading the z4root took forever because while on the site I could not figure out how to download. There were many different versions so maybe I got the wrong one. Help!!!
