Help Stuck in boot loop, no root, no recovery.


Hi All,
I'm so excited because I just got my Nexus 7. However, after a few hours of downloading and playing, the device simply turned off and went into an infinite reboot loop where the Google screen and then X screen was shown. Occasionally, it would show about 5 seconds of the lock screen, but you are not able to touch anything. It just goes back to the boot loop. Also, I've tried to go into recovery, it just stays at the black Google screen forever. Any tips? Might the device be DOA/Bricked?:thinking::thinking::thinking::thinking:
Thanks a lot.
