Hello Guys:

Im new at this. I have the HTC Evo and by mistake I updated the software now I have the 1.47.651.1 version. Ive benn trying to root my phone because Im in a military base right now and we dont have wifi access and I cant install this free wifi hot spot tether in the phone because its not root. Can someone plese tell me what I need to download and do in order to root my phone, i really appreciate if anyone can help with this issue I really need it. And by the way Im kind of dumb at this so the better you guys can explain the better will be for me to do this thing. Thanks and have a great day......
