you have to do the simple root.. all you do is download the file on a windows computer HERE IS THE LINK
[Program] Updated: 1 Click SimpleRoot OTA 1.47.651.1 Edition - xda-developers
download run the program and then plug your phone in with usb debugging enabled.. first click the root button then it'll do all this stuff and the command box will turn red and follow the last few lines in the command box.. once thats done let the phone load back to the normal screen (lock screen / home screen). then you hit the 2nd button which is flash recovery. that'll do some more fancy stuff.. once again you'll return to the home screen again and then follow this guide using the 1.32.651.6 version.. just like the other guy said above... worked for me..
