Use SuperOneClick 1.9
z4root did not work for me at all despite all of the hope I got reading that it worked for others.
I used SuperOneClick v 1.9.**
Make sure you have the drivers installed on your computer.
Turn on usb debug. Start the program and plug the phone in when it says waiting for device...
When it says checking mount path...mount the phone it will finish and give you su permissions and says you are rooted.
Took me 6 hours to root my continuum with all the research and trying over and over, my wife got pretty upset but hey that's life.
Hope this will save others some time.
