I've been trying to root for a while now. Every time i get to the 13th step I type chmod 755 exploid it says unable chmod 755 exploid file not found.
I can find the file though so i dont understand why it won't work.
Simple command line issue. You are not in the right directory OR you are not typing the correct filename. Do a list directory 'ls' and double check that filename is there. I am guessing you missed a 'cd' command somewhere. You can find your present working directory with 'pwd'
