    I was going through the process and I put the overclocking kernel on the sd card. Then selected it through rom manager to use with existing rom, should I have chose to wipe the data instead? because now it will not turn on, it goes to the htc start up screen then restarts every few seconds. When I hold the volume up button it will vibrate a couple times then the phone will stop trying to turn on and I have to take out the battery to get any response. Also the orange light is flashing after the screen turns black.
    I’m worried I screwed my phone for good, voided the warranty my rooting it and I only got it a few days ago.. is there anything I can do?? I’ve tried removing the sim and sd card but there’s no difference.

      The Xoom is not an HTC device. Did you flash it onto a wrong system?
