When I tried rooting my brand new LG Motion, It gave me a whole bunch of lines that I wasn't supposed to. After trying 20 times or so, I discovered that you have to do things EXACTLY the way the directions are written out. Don't do something ahead of time while you are waiting. When I finally did it one step at a time, it worked great. Then I had to do my sons phone.
First time it didn't work. The command prompt takes you back to where all you have to do is type 'root' again. I did and it worked perfectly.
I have 10 thumbs. If can do this ANYBODY can!
