This was my first attempt to root and I'm not sure if I screwed the pooch or what..
I tried to put JB in pretty sure I did it correct but, ever since I tried to load it up it rebooted into the X and hasn't changed.
I had pulled the Battery and held the up/down/pwr and tried all the options either goes back to the X or to the android on his back with the red triangle question mark inside.
I'm on a mac and can not see the nexus something triggers it to let it know somethings there but, say I have to replug in or restart the device...I did get a fastboot command error -2147483647 at one point havent seen it again....then another time it saying Downloading do not change the target or something like that.
I lost and probably screwed ...so if ya got advice...i'll give it a go.
