I have a samsung epic 4g, rooted with Kernel version 220.127.116.11-gefb31a4. I had someone do it for me. Sorry If this has already showed up but I am desperate. I cannot find the exact problem on this site. I installed PDA net on my phone and on my macbook pro. I see the Icon on the top bar of my mac but there is always a red "X". I clicked debugging and everything the application told me to do on my phone and on my computer but every time I plug it in and press connect, my mac tell me there is no phone connected. I have done all the proper updates. my goal is not to have to always use my wifi tethering.
