Ok, first time rooter here and following these steps from the rooting 3.7 guide posted here. I'm currently on step 8, copied first line "adb shell" and now I've seen what appears to be a dollar sign for maybe 10 minutes or so. Tried hitting enter and dollar sign prompt keeps appearing. Did something go wrong? I've followed it to a "T" so far but now I'm in limbo - please HELP!!!
